Bruxismo y su asociación con la disfunción temporomandibular en niños. Revisión de literatura / Bruxism and its association with temporomandibular disorders in children. Literature review

Resumen Introducción: El bruxismo está definido como una actividad oral motora que consiste en el apretamiento o rechinamiento involuntario (rítmico o espasmódico no funcional) de los dientes, con una prevalencia de 5,9% a 49,6% en niños. Lo que podría contribuir a problemas clínicos asociados con la articulación temporomandibular. La asociación entre la disfunción temporomandibular (DTM) y el bruxismo en niños aún no está totalmente establecida. Objetivo: El objetivo de esta revisión de literatura es recopilar información actualizada de estudios que hayan abordado la asociación entre el bruxismo y la disfunción temporomandibular en niños de 3 a 12 años. Metodología: Se realizó una búsqueda en las bases de datos de Scopus, Pubmed y Scielo usando los descriptores "Niño", "Niños", "Preescolar", "Bruxismo", "Bruxismo del sueño", "Disfunción Temporomandibular"; y, "Síndrome de la Disfunción de Articulación Temporomandibular". Fueron incluidos artículos publicados en los últimos 15 años en idiomas español, inglés y portugués. Fueron incluidos estudios transversales, de cohorte, casos controles y ensayos clínicos aleatorizados. Resultados: Se evaluaron 242 artículos, de los cuales solo 11 fueron incluidos de acuerdo a los criterios de inclusión. Entre los estudios incluidos, dos de ellos no encontraron asociación entre DTM y bruxismo, tres encontraron una tendencia o probable asociación y seis encontraron una asociación positiva. Conclusiones: Existen estudios que relatan asociación entre el bruxismo y las disfunciones temporomandibulares en niños de 3 a 12 años, relacionando la presencia de signos y síntomas de la DTM con el bruxismo, pudiendo ser este último, un factor de riesgo para la presencia de DTM.

ABSTRACT Introduction: Bruxism is defined as an oral motor activity that consists of involuntary clenching or grinding (non-functional rhythmic or spasmodic) of the teeth, with a prevalence rate ranging from 5.9% to 49.6% in children, which could contribute to clinical problems associated with the temporomandibular joint. The association between bruxism in children and temporomandibular dysfunction (TMD) is not yet fully established. Objective: The objective of this literature review is to collect up-to-date information on studies that have addressed the association between bruxism and temporomandibular dysfunction in children ranging 3 - 12 years of age. Methods: A search was performed in the Scopus, PubMed and SciELO databases using the descriptors "Child", "Children", "Child, Preschool", "Bruxism", "Sleep Bruxism", "Temporomandibular Dysfunction" and "Temporomandibular Joint Dysfunction Syndrome." Articles published in the last 15 years in the Spanish, English and Portuguese languages were included. Results: A total of seventy-two articles were assessed. Only 11 articles were included according to the inclusion criteria. Among the included studies, two of them found no association between TMD and bruxism, three found a trend or probable association, and six found a positive association. Conclusion: There are studies that report an association between bruxism and temporomandibular dysfunctions in children ranging 3 - 12 years old, relating the presence of signs and symptoms of TMD with bruxism.

Prevalence and Risk Factors of Bruxism in a Selected Population of Iranian Children

ABSTRACT Objective: To investigate the prevalence of bruxism in Iranian children aged 6 to 12 years. Material and Methods: This cross-sectional study was conducted on 600 schoolchildren aged 6-12 years. The questionnaire consisted of two sections: the first section included demographic information, while the second evaluated the occurrence of bruxism. Kruskal-Wallis, Chi-Square, Fisher and Multinomial logistic regression were used. A level of p<0.05 was considered statistically significant. Results: 698 questionnaires were distributed, of which 600 participants were returned. According to Multinomial logistic regression, awake bruxism was associated significantly with the following variables: age, sequence of birth, recurrent headache, gastrointestinal disease, nasal obstruction, neurological disorder, easy child crying, sleep disorders, talking in a dream and snoring and jaw disorder. Sleep bruxism was associated significantly with age, premature birth, allergy, gastrointestinal disease, drooling, mouth breathing, nasal obstruction, oral habit, nail biting, sleep disorder, jaw disorders, and family history. Conclusion: Pre-birth and post-birth factors play an important role in the prevalence of bruxism in society. It is possible to prevent complications of bruxism by informing parents and making a timely diagnosis. Parents should be aware of this occurrence to reduce possible related factors to teeth and the masticatory system.

Tooth wear due to dental attrition among 12-year-old adolescents / Desgaste dentário por atrição entre adolescentes de 12 anos de idade

Aim: To evaluate the prevalence and distribution of tooth wear due to dental attrition among 12-year-old adolescents according to their gender, reports of tooth grinding during sleep/while awake (bruxism), and sleep features related to sleep-disordered breathing. Methods: A cross-sectional study was conducted with 172 adolescents from southeast Brazil. Parents/caregivers answered questions about sociodemographic characteristics; reports of adolescents' tooth grinding during sleep, and sleep features (e.g. sleep duration and position, snoring, drooling on the pillow) in the previous two weeks. Adolescents self-reported the occurrence of tooth clenching/grinding while awake in the previous two weeks. Tooth wear due to dental attrition was assessed by a previously calibrated researcher, using a validated 5-point analogical ordinal occlusal/incisal tooth wear grading scale, with scores ranging from 0 (no wear) to 4 (loss of crown height ≥ 2/3), depending on tooth wear severity. Descriptive statistics and the Mann-Whitney test (p < 0.05) were performed to identify differences in tooth wear due to the distribution of dental attrition, according to adolescents' characteristics. Results: Most adolescents were female (58.0%) and 81.6% of the participants presented tooth wear due to dental attrition within the enamel. Adolescents who snored had a higher number of incisors with tooth wear due to dental attrition (p = 0.035). Females showed a higher number of canines with tooth wear due to dental attrition (p = 0.020). Adolescents whose parents reported tooth grinding during sleep presented a higher number of bicuspids with tooth wear due to dental attrition (p = 0.001). Conclusion:Tooth wear due to dental attrition within the enamel was observed in most adolescents. The distribution, depending on specific groups of teeth, was higher among female adolescents, adolescents' whose parents reported tooth grinding, and adolescents who snored during sleep.

Objetivos: Avaliar a prevalência e distribuição de DDA entre adolescentes de 12 anos de acordo com o sexo, relato de ranger de dentes durante o sono e vigília (bruxismo) e características relacionadas a desordens respiratórias do sono.Método: Desenvolveu-se um estudo transversal com 172 adolescentes do sudeste do Brasil. Seus pais/responsáveis responderam um questionário contendo informações sociodemográficas, relato sobre os filhos rangerem os dentes durante o sono e hábitos do sono dos filhos (duração do sono, posição que dorme, roncar, babar no travesseiro) nas duas últimas semanas. Adolescentes relataram ocorrência de ranger/apertar de dentes durante a vigília nas duas últimas semanas. DDA foi avaliado por um pesquisador previamente calibrado através de uma escala analógica ordinal de cinco pontos de desgaste dentário para faces oclusal/incisal previamente validada, com escores variando de 0 (sem desgaste) a 4 (perda da coroa em altura ≥ 2/3), dependendo da gravidade do desgaste. Análises descritivas e teste de Mann-Whitney (p < 0,05) foram realizados para identificar as diferenças na distribuição de DDA de acordo com as características dos adolescentes.Resultados: A maioria dos adolescentes eram meninas (58,0%) e 81,6% dos participantes apresentaram DDA em esmalte em algum elemento dentário. Adolescentes que rocavam apresentavam mais incisivos com DDA (p = 0.035). Meninas apresentaram maior número de caninos com DDA (p = 0.020). Adolescentes que rangiam os dentes durante a noite apresentaram maior número de pré-molares com DDA (p = 0.001).Conclusão: Desgaste dentário por atrição em esmalte foi observado na maioria dos adolescentes. A distribuição, dependendo de grupos de dentes específicos, foi maior entre meninas, adolescentes que roncavam durante o sono e que rangiam os dentes durante o sono.

Bruxism an issue between the myths and fact / Bruxismo, un problema entre los mitos y los hechos

Abstract Is our goal in this paper to discuss the current concepts about bruxism, a topic that has been a matter of discussion on the dental field for many years. Recent International efforts have been made to challenge bruxism old definitions; this has derivate to a consensus and an actual new concept that defines bruxism as a behavior instead of a disorder. As a behavior, it is explained in this review how it can have negative health consequences, can be innocuous and how new research support that bruxism can even be a protective factor. Different etiological factors are reviewed in this paper as well the influence of external and internal mechanism related to medications, emotional stress, systemic factors, and potential pharmacological pathways. Moreover, it is briefly summarized the role of oral appliances on sleep bruxism. Finally, clinical considerations and recommendation for the dental professional regarding sings that should be notice during the exam are part of this overview.

Resumen Es nuestro objetivo en este artículo discutir los conceptos actuales sobre el bruxismo, un tema que ha sido motivo de discusión en el campo odontológico durante muchos años. Se han hecho esfuerzos internacionales recientes para desafiar las viejas definiciones de bruxismo; esto ha derivado en un consenso y en la actualidad un nuevo concepto que define al bruxismo como un comportamiento en lugar de un trastorno. Como conducta, se explica en esta revisión cómo puede tener consecuencias negativas para la salud, puede ser inocuo y cómo nuevas investigaciones avalan que el bruxismo puede incluso ser un factor protector. En este artículo se exponen diferentes factores etiológicos, así como la influencia de mecanismos externos e internos relacionados como: medicamentos, estrés emocional, factores sistémicos y posibles vías farmacológicas. Además, se resume brevemente el papel de los aparatos orales en el bruxismo del sueño. Finalmente, se presentan consideraciones clínicas y la recomendación para el profesional en odontología con respecto a los signos que deben ser observados durante el examen clínico son parte de esta revisión.

Factores de riesgo relacionados al bruxismo del sueño en niños de 3 a 12 años: revisión de literatura / Risk factors related to sleep bruxism in children: literature review

Resumen Introducción: El bruxismo del sueño (BS) es una actividad del músculo masticatorio durante el sueño que se caracteriza por ser rítmica o no rítmica que no debe ser considerada un trastorno del sueño o movimiento por sí sola. Objetivo: Revisar información de artículos relacionados a los factores de riesgo del bruxismo del sueño en niños de 3 a 12 años. Metodología: La estrategia de búsqueda de artículos fue realizada en las siguientes bases de datos electrónicos: PubMed, Ebsco, Web of Science y Scielo. Los descriptores: niños, pre-escolares, bruxismo, factores de riesgo y bruxismo del sueño fueron utilizados en la búsqueda. Los criterios de selección incluyeron artículos publicados desde el 2009 al 2020 en idioma inglés y español. Estudios transversales, estudios de cohorte, casos controles y ensayos clínicos aleatorizados que reportaron factores de riesgo del BS en niños de 3 a 12 años de edad fueron incluidos. Dos revisores examinaron de forma independiente los títulos y los resúmenes. Luego, los resúmenes considerados relevantes se programaron para la revisión del texto completo. En esta revisión, no existió discrepancias entre los dos revisores. Resultados: Después de aplicar los criterios de inclusión, se incluyeron veintidós artículos. Entre los artículos seleccionados, no hubo asociación entre edad y SB en niños. Conclusiones: De acuerdo con la información disponible, se considera que la genética, sexo masculino, ansiedad, desordenes psicológicos y emocionales, hábitos orales nocivos, el cronotipo del sueño, problemas y/o características del sueño y problemas respiratorios son factores de riesgo relacionados al bruxismo del sueño en niños de 3 a 12 años. Sin embargo, la asociación con maloclusiones aún necesita más estudios.

Abstract Introduction: Sleep bruxism (SB) is an activity of the masticatory muscle during sleep that could be rhythmic or non-rhythmic. Also, SB should not be considered a sleep or movement disorder by itself. Objective: To review information from studies related to risk factors of sleep bruxism in children aged 3 to 12 years old. Methods: The search for literature was performed in the following electronic databases: PubMed, Ebsco, Web of Science and Scielo. The terms children, pre-school, bruxism, risk factors, and sleep bruxism were used to search. The selection criteria included articles published from 2009 to 2020 in English and Spanish languages. Cross-sectional studies, cohort studies, case controls and randomized clinical trials which reported risk factors related to sleep bruxism in children aged 3 to 12 years-old were included. Two reviewers independently screened titles and abstracts. Then, abstracts considered relevant were scheduled for full-text review. In this review, there was no discrepancias between the two reviewers. Results: After applying the inclusion criteria, twenty-two articles were included. Among selected articles, there were no association between age and SB in children. Conclusions: According to the available information, genetics, male gender, anxiety, psychological and emotional disorders, chronotype sleep profiles, oral habits, characteristics and/or sleep problems; and respiratory difficulties are considered as risk factors related to sleep bruxism in children aged 3 to 12 years old. However, the association with malocclusions needs further studies.

Bruxismo do sono e em vigília em adolescentes: prevalência, fatores associados e análise de caminhos / Sleep and awake bruxism in adolescents: prevalence, associated factors and pathways to occurrence

O Bruxismo é um comportamento, com atividade muscular mastigatória, que pode apresentar-se como bruxismo do sono (BS) e bruxismo em vigília (BV). Possui etiologia multifatorial, sendo pouco explorado entre adolescente. Essa tese é composta por dois artigos que avaliam a prevalência, fatores associados e análise de caminhos. O objetivo do artigo 1 (n=403) foi reconhecer os caminhos que influenciam a ocorrência de provável bruxismo do sono (PBS) e provável bruxismo em vigília (PBV) em adolescentes. O artigo 2 (n=342) objetivou avaliar a associação entre PBV e hábitos de morder, satisfação de vida, caracteristicas do sono e perfil cronotipo em adolescentes, por meio de um estudo caso-controle. Com aprovação do comitê de ética institucional, participaram do estudo adolescentes de 12 a 19 anos de idade, regularmente matriculados em escolas públicas e privadas de Belo Horizonte. Os pais/cuidadores responderam a um questionário sobre características do sono de seus filhos. Os adolescentes responderam aos seguintes instrumentos: questionário sobre hábitos de morder, características do sono e relato de bruxismo; a escala "The Circadian Energy Scale" (CIRENS), para mensurar o perfil cronotipo; e o dominio self da versão brasileira da Escala Multidimensional de Satisfação de Vida para Adolescentes (EMSVA). O PBS e PBV foram mensurados considerando o auto relato positivo, somado à presença de desgaste dentário por atrição aferido em exame clinico feito pela pesquisadora previamente calibrada. A análise descritiva foi incluida nos artigos 1 e 2. O artigo 1 usou a análise de caminhos, tecnica que descreve as dependências direcionadas entre um conjunto de variáveis. No artigo 2 foi feita regressão logistica condicional (OR) (p<0,05). Como resultados no artigo 1, verificou-se que 22,3% dos adolescentes apresentaram PBS e 51,1% PBV. As duas manifestações de bruxismo apresentaram associação entre si, com uma correlação moderada e positiva (ß= 0,390). Qualidade do sono e renda familiar tiveram um efeito direto sobre PBS (ß= - 0,138; ß=0,123; respectivamente) e em PBV (ß= - 0,155; ß=0,116; respectivamente), de modo que aqueles com maior renda e com má qualidade do sono tenderam a apresentar provável bruxismo tanto BS, quanto BV. Cronotipo teve efeito direto sobre o PBS, de modo que adolescentes com cronotipo matutino tenderam a ter o comportamento (ß= -0,102). Adolescentes que relataram babar no travesseiro enquanto dormiam (ß= 0,184) e/ou que tinham sono agitado (ß= 0,104) tenderam a apresentar PBS. Já no artgido 2 verificou-se que má qualidade do sono (OR=1,731, IC95% 1,054-2,842, p=0,030), hábito de morder objetos muitas vezes (OR=3,303, IC95% 1,631-6,690, p=0,001), hábito de morder ou apertar os lábios algumas vezes (OR=2,134, IC95% 1,230-3,702, p=0,007) e hábito de morder ou apertar os lábios muitas vezes nas duas semanas anteriores à avaliação (OR=2,355, IC95% 1,203- 4,608, p=0,012) foram associados à ocorrencia de PBV. Concluiu-se com o artigo 1 que o perfil cronotipo, renda familiar e caracteristicas do sono influenciaram no caminho percorrido pelo PBS, enquanto renda e qualidade do sono influenciam o PBV. Enquato atraves do artigo 2, concluiu- se que adolescentes com má qualidade do sono e que apresentam habitos de morder tiveram mais chance de apresentar PBV.

Bruxism is a behavior, with masticatory muscle activity, which can present itself as sleep bruxism (SB) and awake bruxism (AB). It has a multifactorial etiology, and is little explored among adolescents. This thesis is composed of two articles assessing prevalence, associated factors, and path analysis. The objective of article 1 (n=403) was to recognize the pathways influencing the occurrence of probable sleep bruxism (PSB) and probable awake bruxism (PAB) in adolescents. Paper 2 (n=342) aimed to evaluate the association between PSB and biting habits, life satisfaction, sleep characteristics and chronotype profile in adolescents by means of a case-control study. After approval by the institutional ethics committee, adolescents aged 12 to 19 years, regularly enrolled in public and private schools in Belo Horizonte, Brazil, participated in the study. Parents/caregivers answered a questionnaire about their children's sleep characteristics. The adolescents answered the following instruments: a questionnaire about biting habits, sleep characteristics and bruxism report; the Circadian Energy Scale (CIRENS), to measure the chronotype profile; and the self domain of the Brazilian version of the Multidimensional Life Satisfaction Scale for Adolescents (MLSSA). The PSB and PAB were measured considering the positive self-report, added to the presence of attrition dental wear measured in a clinical examination performed by a previously calibrated researcher. Descriptive analysis was included in articles 1 and 2. Article 1 used path analysis, a technique that describes the directed dependencies among a set of variables. In article 2, conditional logistic regression (OR) was performed (p<0.05). As results in article 1, it was found that 22.3% of the adolescents presented PSB and 51.1% PAB. The two manifestations of bruxism showed an association with each other, with a moderate and positive correlation (ß= 0.390). Sleep quality and family income had a direct effect on PSB (ß= - 0.138; ß=0.123; respectively) and on PAB (ß= -0.155; ß=0.116; respectively), so that those with higher income and poor sleep quality tended to show likely bruxism in both SB and AB. Chronotype had a direct effect on PSB, such that adolescents with morning chronotype tended to have the behavior (ß= -0.102). Adolescents who reported drooling on the pillow while sleeping (ß= 0.184) and/or who had restless sleep (ß= 0.104) tended to present PSB. In artgid 2, on the other hand, it was found that poor sleep quality (OR=1.731, 95%CI 1.054-2.842, p=0.030), habit of biting objects often (OR=3.303, 95%CI 1.631-6.690, p=0.001), habit of biting or tightening lips sometimes (OR=2, 134, 95%CI 1.230-3.702, p=0.007) and biting or lip-squeezing often in the two weeks prior to evaluation (OR=2.355, 95%CI 1.203- 4.608, p=0.012) were associated with the occurrence of PAB. It was concluded with article 1 that the chronotype profile, family income and sleep characteristics influence the path taken by PSB, while income and quality of sleep influence PAB. In article 2, it was concluded that adolescents with poor sleep quality and those with biting habits were more likely to present PAB.

Association between self-reported bruxism and academic performance in university students / Asociación entre bruxismo autorreportado y rendimiento académico de los estudiantes universitarios

Objective: To evaluate the association between self-reported bruxism and academic performance in students at a university in Lima, Peru. Material and Methods: A total of 203 students were evaluated in this study, between the ages of 19 and 35 years. Self-reported bruxism was measured using the Bruxism Assessment Questionnaire. Academic performance was evaluated using the Approval Index Scale. In addition, other variables were included such as employment status, socioeconomic level, stress, anxiety, among others. The association of variables were factored in using the chi-square test and the logistic regression presented the unadjusted and adjusted analisis. Results: The frequency of self-reported awake bruxism and sleep bruxism was 53.20% and 36.45%, respectively. Evidence revealed there was a statistically significant association between awake bruxism with stress and anxiety, and sleep bruxism with anxiety. Students with high academic performance (OR=2.36; IC del 95%:1.06-5.23) and low academic performance (OR=5.72; IC del 95%:1.28-25.57) were found to be more likely to have awake bruxism than those with medium academic performance. Conclusion: This study revealed a statistically significant association between self-reported awake bruxism and academic performance. However, in the future it is suggested to carry out a study with focus only on students with bruxism and with a larger sample of participants with low academic performance to confirm the association found between these variables.

Objetivo: Evaluar la asociación entre bruxismo autorreportado y rendimiento académico en estudiantes de una universidad privada de Lima, Perú. Material y Métodos: Un total de 203 estudiantes con edades comprendidas entre 18 a 35 años fueron encuestados en esta investigación. Para la evaluación del bruxismo autoreportado se aplicó el cuestionario 'Bruxism Assessment Questionnaire' en su versión en español. Asimismo, el rendimiento académico se evaluó mediante la escala de Índice de Aprobación (IA). Además, se incluyeron otras variables como situación laboral, estrés, ansiedad, entre otros. La asociación de variables se realizó mediante la prueba chi cuadrado y para el análisis crudo y ajustado se utilizó la regresión logística. Resultados: Se encontró una prevalencia de bruxismo de vigilia de 53.20% y de bruxismo de sueño de 36.45%. Se evidenció asociación estadísticamente significativa entre bruxismo de vigilia con estrés y ansiedad, y bruxismo de sueño con ansiedad. Se halló que los estudiantes con rendimiento académico alto (OR=2.36; IC del 95%:1.06-5.23) y rendimiento académico bajo (OR=5.72; IC del 95%:1.28-25.57) tienen más probabilidades de presentar bruxismo de vigilia que aquellos con rendimiento académico medio. Conclusiones: En el presente estudio se halló asociación estadísticamente significativa entre bruxismo de vigilia autorreportado y rendimiento académico. No obstante, a futuro se sugiere realizar un estudio a los estudiantes con presencia de bruxismo y con un mayor tamaño muestral de participantes con rendimiento académico bajo para afirmar la asociación encontrada entre dichas variables.

Polymorphisms of the serotonin receptors genes in patients with bruxism: a systematic review

Abstract This study aimed to investigate if SNP rs6313, SNP rs2770304, SNP rs4941573, and SNP rs1923884 of the 5-HT2A receptor gene and SNP rs6295 of the 5-HT1A receptor gene are associated with bruxism etiology. Methodology This systematic review was registered in PROSPERO (CRD42018094561). A search was conducted for articles published in or before May 2021. To qualify for eligibility in this review, the studies had to be case-controls, cohort or cross-sectional. The inclusion criteria were the articles with a group of patients with bruxism and a control group in which the presence of these SNPs was evaluated. The exclusion criteria were the investigations of other polymorphisms, the studies that did not consider a control group for comparison, case reports, and reviews. The NOS and JBI were used to evaluate the methodological quality of studies. Results We conducted this study with databases, such as Web of Science, Scopus, Embase, PubMed/MEDLINE, and ProQuest. We considered four studies eligible. A total of 672 participants were included,187 with sleep bruxism, 105 with awake bruxism, 89 with sleep and awake bruxism, and 291 controls. One study found a strong association between the SNPs rs6313, rs2770304 and rs4941573 of the 5-HT2A receptor gene and sleep bruxism. In one study, we considered the C allele of the SNP rs2770304 a risk factor for sleep bruxism. We found no significant results of other SNPs in sleep bruxers compared to controls. We found no positive association concerning the SNPs and groups of awake bruxism and sleep and awake bruxism. Conclusion The different results regarding the SNPs in sleep bruxers could be explained by the genetic distinction between Chilean, Mexican, Japanese, and Polish population. More clinical trials and prospective studies must be conducted with larger sample size and in different ethnicities to confirm the results of this review.

Oral behaviors, bruxism, malocclusion and painful temporomandibular joint clicking: is there an association?

Abstract The present cross-sectional case-control study aimed to determine if there is an association between specific oral behaviors, sleep bruxism (SB), awake bruxism (AB), and painful temporomandibular joint (TMJ) clicking. Ninety individuals were dived into three groups; Group 1 (n = 30): painful TMJ clicking; Group 2 (n = 30): painless TMJ clicking; and Group 3 (n = 30): control group. The following clinical data were studied: oral behaviors (unilateral chewing, gum chewing, nail biting, foreign objects biting, leaning with jaw against the hand, and sleeping in a position that pressures the jaw), SB, AB (including the frequency in 10 days, evaluated by ecological momentary assessment), and malocclusions investigated based on clinical inspections (anterior open bite, posterior cross-bite, abnormal overbite/overjet, occlusal guidance, mediotrusive and/or laterotrusive interferences, retruded contact position to maximum intercuspation slide, missing posterior teeth). All statistical tests (Kolmogorov-Smirnov, chi-square, and one-way ANOVA) were performed with a 5% significance level. Group 1 had the highest frequency of and a significant association with leaning with jaw in the hand, sleeping position that pressures the jaw, gum chewing, nail biting, and AB (p<0.05). Gum chewing, nail biting, and AB were associated with Group 2 only when compared to Group 3 (p<0.05). No significant difference among groups was found for other behaviors (unilateral chewing and foreign objects biting), SB, and all malocclusions (p>0.05). It can be concluded that patients with painful TMJ clicking had a higher frequency of and a significant association with some specific harmful behaviors and AB.

Association of sleep quality and psychological aspects with reports of bruxism and TMD in Brazilian dentists during the COVID-19 pandemic

Abstract Dentists are exposed to contamination by SARS-CoV-2 due to dental interventions, leading to a state of alert and potential risk of negative impact in mental health and sleep quality, associated with Temporomandibular Disorder (TMD) and bruxism. Objective: to evaluate the psychosocial status, sleep quality, symptoms of TMD, and bruxism in Brazilian dentists (DSs) during the COVID-19 pandemic. Methodology: The sample (n=641 DSs) was divided into three groups (quarantined DSs; DSs in outpatient care; and frontline professionals), which answered an electronic form containing the TMD Pain Screening Questionnaire (Diagnostic Criteria for Temporomandibular Disorders - DC/TMD), the Pittsburgh Sleep Quality Index (PSQI), the Depression, Anxiety and Stress Scale (DASS-21), and the sleep and awake bruxism questionnaire. ANOVA test and Mann Whitney post-test were used, with Bonferroni adjustment (p<0.016) and a 95% confidence level. Results: Probable TMD was found in 24.3% (n=156) of the participants, while possible sleep and awake bruxism were diagnosed in 58% (n=372) and 53.8% (n=345) of them, respectively. Among all variables evaluated, only symptoms of depression were significantly greater in the quarantined DSs group when compared to those who were working at the clinical care (p=0.002). Working DSs were significantly less likely (OR=0.630, p=0.001) to have depressive symptoms. Those who were not worried or less worried about the pandemic were less likely to experience stress (OR=0.360), anxiety (OR=0.255), and poor sleep quality (OR=0.256). Sleep had a strong positive and moderate correlation with psychological factors on frontline workers and DSs in outpatient care, respectively. Conclusion: The results suggest confinement may have a more negative impact on the life of DSs than the act of being actively working. The concern about Covid-19 and poor sleep quality was significantly prevalent and may negatively affect the quality of life of DSs. Thus, further research on the topic is needed.

Auriculotherapy for sleep bruxism in children: a series of cases

Sleep bruxism is defined as a behavior that causes masticatory muscle activities during sleep. Sleep bruxism in childhood leads to consequences, which may vary from teeth wear in deciduous dentition to temporomandibular disfunction symptoms. There's no data that demonstrates improvement of children with sleep bruxism during and after auricular acupuncture treatment. Objective: Therefore, this case report series aimed to evaluate the effect of auriculotherapy on children presenting sleep bruxism. Methods: Twelve patients were included in this study, in the mean age of 6,9. The diagnosis was evaluated by the question: "Does your kid grind their teeth while sleeping?". Treatment was performed by an acupuncture specialist in a standardized way. The therapy was given for three weeks and the effect was evaluated through a sleep diary, in which the parents noted whether or not their child grinded teeth while sleeping before (baseline) and during therapy (T1 to T3). Sleep bruxism was categorized as presence or absence of nocturnal teeth grinding and the frequency varied from 0 to 7 (baseline), 0 to 5 (T1), 0 to 7 (T2) and 0 to 4 (T3) between patients. The intensity of the reported sleep bruxism was compared according to the periods by pared T-test ( =0.05). Results: It was observed that the frequency of reports decreased significantly from baseline to T3. Conclusion: These results suggest that ear acupuncture may be an alternative therapy for sleep bruxism in childhood, once it demonstrated to reduce its frequency in this study, although patients may present different effects to therapy due to biological variability.

Introdução: Bruxismo do sono é definido como um comportamento que causa atividades musculares durante o sono. Na infância, leva a consequências que podem variar de desgaste dentário na dentição decídua a sintomas de disfunção temporomandibular. Não há estudos que demonstrem melhora de casos de crianças com bruxismo do sono durante e após tratamento com auriculoterapia. Objetivo: portanto, esta série de casos visou avaliar o efeito da auriculoterapia em crianças apresentando este quadro. Métodos: Doze pacientes foram inclusos neste estudo, com a media de idade de 6,9. O diagnóstico foi avaliado pela pergunta "Seu filho range os dentes quando dorme?". O tratamento foi executado por um especialista em acupuntura de forma padronizada. A terapia foi feita por três semanas e o efeito foi avaliado através de um diário do sono, no qual os pais anotavam se a criança rangeu os dentes enquanto dormia antes (baseline) e durante a terapia (T1 a T3). Bruxismo do sono foi categorizado como presença ou ausência de ranger de dentes e a frequência variou de 0 a 7 (baseline), 0 a 5 (T1), 0 a 7 (T2) e 0 a 4 (T3) entre os pacientes. A intensidade foi comparada de acordo com os períodos pelo teste-T pareado (=0,05). Resultados: Foi observado que a frequência de relatos diminuiu significativamente de baseline a T3. Conclusão: Estes resultados sugerem que auriculoterapia pode ser uma terapia alternativa para o bruxismo do sono na infância, uma vez que demonstrou reduzir sua frequência neste estudo, embora os pacientes possam apresentar efeitos diferentes devido à variabilidade biológica.

Comparison between sleep disorders and polysomnographic records of young adults with and without sleep bruxism: a cross-sectional study / Comparación entre trastornos del sueño y registros polisomnográficos de adultos jóvenes con y sin bruxismo del sueño: un estudio transversal

Objectives: To compare sleep disorders and polysomnographic records among a group of young adults with sleep bruxism (SB) and a control group (C). Material and methods: This cross-sectional study considered a consecutive sampling of students from the target population, searching for cases of SB until 20 individuals with and without SB were obtained. Sleep disorders were determined by applying both medical records and physiological records during sleep which were gathered from a polysomnography exam. To establish the difference of the means according to SB, the T-Student or Mann-Whitney U tests were used, depending on the data. A Logistic Regression analysis was also applied. Results: The study found differences (p-value<0.05) in the variables related to the sleep disorder: the possibility of major depressive episode (SB: 30% - C: 5%), degree of nasal airway obstruction (SB: 20% - C: 10%) and in polysomnographic registers: sleep time stage 1 (SB: 9 min - C: 18 min), Rapid Eye Movement (REM) stage (SB: 123 min C: 93 min ), number of periodic movement of the limbs (SB: 84.2 - C: 49.7), bruxism index (SB: 40.2 - C: 10.1) and average of total arousals (SB: 71.9 - C: 57.5). According to the logistic regression model, the Odds Ratio (OR) of SB, in relation to the periodic movement of the limbs and the degree of airway obstruction, it showed a statistically significant relationship (p-value<0.05). Conclusion: There were significant differences recorded in two sleep disorders between the two groups: the degree of airway obstruction and the possibility of having a major depressive episode. Differences were found in sleep and REM time stages, periodic movement of limbs and bruxism events.

Objetivo: Comparar los trastornos del sueño y los registros polisomnográficos entre un grupo de adultos jóvenes con bruxismo del sueño (BS) y un grupo control (C). Material y Métodos: Este estudio transversal consideró una muestra consecutiva de estudiantes de la población objetivo, buscando casos de BS hasta obtener 20 individuos con y sin BS. Los trastornos del sueño se determinaron aplicando registros médicos y fisiológicos durante el sueño que se obtuvieron de un examen de polisomnografía. Para establecer la diferencia de las medias según BS se utilizaron las pruebas t-Student o U de Mann-Whitney, según los datos. También se aplicó un análisis de regresión logística. Resultados: El estudio encontró diferencias (p<0,05) en las variables relacionadas con el trastorno del sueño: posibilidad de episodio depresivo mayor (BS: 30% - C: 5%), grado de obstrucción de la vía aérea nasal (BS: 20% - C: 10%) y en registros polisomnográficos: tiempo de sueño etapa 1 (BS: 9 min - C: 18 min), etapa de Movimiento Ocular Rápido (REM) (SB: 123 min C: 93 min), número de movimientos periódicos del extremidades (BS: 84.2 - C: 49.7), índice de bruxismo (BS: 40.2 - C: 10.1) y promedio de despertares totales (BS: 71.9 - C: 57.5). Según el modelo de regresión logística, el Odds Ratio (OR) del BS, en relación al movimiento periódico de las extremidades y al grado de obstrucción de la vía aérea, mostró una relación estadísticamente significativa (p<0,05). Conclusión: Se registraron diferencias significativas en dos trastornos del sueño entre los dos grupos: el grado de obstrucción de la vía aérea y la posibilidad de tener un episodio depresivo mayor. Se encontraron diferencias en las etapas de sueño y tiempo REM, movimiento periódico de extremidades y eventos de bruxismo.

Bruxismo nocturno y síndrome de dolor miofascial / Sleep bruxism and myofascial pain syndrome

El bruxismo es un factor iniciador y coadyuvante de alteraciones de la región temporomandibular, entre las que se incluye el síndrome de dolor miofascial. Sin embargo, en los diversos estudios realizados en la literatura científica no hay homogeneidad en los métodos diagnósticos, en la clasificación de bruxismo o en las alteraciones temporomandibulares, lo que no permite asegurar que existe una relación causa-efecto entre el bruxismo y los diferentes desórdenes temporomandibulares. Para intentar aclarar la relación entre el bruxismo y el síndrome de dolor miofascial se realizó una revisión sistemática de la literatura sobre estudios que hayan buscado identificar la asociación entre las dos condiciones. Los estudios que han sugerido una relación causal entre bruxismo nocturno y dolor miofascial han utilizado métodos diagnósticos variables, apoyándose, principalmente, en encuestas de corte transversal, lo cual ha limitado la posibilidad de lograr conclusiones firmes; mientras que aquéllos que usan métodos objetivos, como polisomnografía, no han encontrado una concluyente relación causal (AU)

Bruxism is an initiating and coadjuvant factor of temporomandibular disorders, including myofascial pain syndrome. However, in the various studies conducted in the scientific literature, there is a lack of consistency in diagnostic methods, the classification of bruxism, or temporomandibular disorders, which has prevented to ensure that there are a cause and effect relationship between bruxism and the different temporomandibular disorders. To try to clarify the relationship between bruxism and myofascial pain syndrome, a systematic review of the literature was carried out on studies that have sought an association about these two conditions. Studies that have found a causal relationship between nocturnal bruxism and myofascial pain have used variable diagnostic methods, relying mainly on surveys, which has limited the possibility of reaching firm conclusions; while those who used objective methods, such as polysomnography, have not found a conclusive causal relationship (AU)

Bruxismo en niños y adolescentes: Revisión de la literatura / Bruxism in Children and Adolescents: A Review of the Literature

Resumen: El bruxismo se define como una actividad repetitiva de los músculos masticatorios caracterizada por apretar o rechinar los dientes y/o por golpear y balancear la mandíbula. Es de etiología multifactorial y se considera que existe un bruxismo fisiológico necesario para el desarrollo de la cara de los niños. Estos dos aspectos hacen complicado el diagnóstico que se basa fundamentalmente en un cuestionario a los padres y en el examen clínico del niño. Cuando el desgaste fisiológico no se diferencia a tiempo del desgaste parafuncional, trae consecuencias negativas en el niño que alteran su calidad de vida, necesitando un manejo multidisciplinario adecuado. Considerando que es necesario conocer características fundamentales del bruxismo infantil, el objetivo del presente artículo de revisión es realizar una actualización sobre sus manifestaciones circadianas, clasificaciones, prevalencia, etiología, factores de riesgo, diagnóstico y tratamiento que servirá al odontólogo para una temprana identificación y tratamiento.

Abstract: Bruxism is defined as a repetitive activity of the chewing muscles characterized by clenching or grinding of the teeth and/or by striking and swinging the jaw. It is of multifactorial etiology and it is considered that there is a physiological bruxism necessary for the development of the face of children. These two aspects complicate the diagnosis that is fundamentally based on a questionnaire to the parents and on the clinical examination of the child. When the physiological wear does not differentiate in time from the parafunctional wear, it has negative consequences in the child that alter their quality of life, requiring an adequate multidisciplinary management. Considering that it is necessary to know the fundamental characteristics of bruxism in children and adolescents, the objective of this review article is to update its circadian manifestations, classifications, prevalence, etiology, risk factors, diagnosis and treatment that will serve the dentist for the early identification and treatment.

CONTROLE DO BRUXISMO DO SONO NA INFÂNCIA: REVISÃO DE LITERATURA / CONTROL OF SLEEPING BRUXISM IN CHILDHOOD: LITERATURE REVIEW

O bruxismo em crianças tem se tornado uma preocupação crescente nos últimos anos. É definido como uma atividade involuntária dos músculos mastigatórios caracterizada por apertar ou ranger os dentes e pode ser de dois tipos, do sono (BS) ou da vigília (BV). A prevalência do BS na população infantil varia de 5,9% a 49,6%.Fatores funcionais, estruturais e psicológicos podem estar envolvidos com a presença do bruxismo. O diagnóstico é feito por meio de questionários, exame clínico e exame de polissonografia, que é o padrão ouro. Por ser uma desordem de origem central e não periférica, o BS não tem cura. Logo, faz-se o controle, que abrange prevenção, abordagem e gerenciamento de consequências. Atualmente, são citadas na literatura inúmeras técnicas de manejo para oBS. Este trabalho tem o objetivo de revisar a literatura atual referente ao controle do BS em crianças e confeccionar uma cartilha informativa direcionada aos pais, expondo os benefícios da higiene do sono como controle basal do BS. Conclui-se que a higiene do sono, apesar de baixa evidência científica, é considerada a primeira linha de abordagem para o bruxismo do sono infantil.

Children bruxism has become a growing worry in the last years. It is defined as an involuntary activity of masticatory muscles characterized by tightening or gritting the teeth and can be of two types, sleep (SB) or wake (WB). The prevalence of SB in infant population varies from 5,9% to 49,6%. Functional, structural and psychological factors may be involved in the presence of bruxism. The diagnosis is made through questionnaires, clinical examination and polysomnography, which is the gold standard. Because it is a central and non-peripheral origin disorder, SB has no cure. Therefore, control is made, which includes prevention, approach and consequence management. Currently, numerous management techniques for SB are cited in the literature. This work aims to review the current literature regarding the control of SB in children and to make an informative booklet directed to parents, exposing the benefits of sleep hygiene as basal control of BS. It is concluded that sleep hygiene, despite low scientific evidence, is considered the first line of approach for children sleep bruxism.

Abstract Introduction: According to the scientific literature, sleep bruxism (SB) could produce orofacial muscle, dental, and temporary headaches as well as postural alterations. Objective: To evaluate the stomatognathic system and the posture of an individual diagnosed with sleep bruxism (SB) from an interdisciplinary approach. Materials and methods: Descriptive study of a case report of a female individual. The SB was determined by polysomnography. Static and dynamic inter-occlusal relationships were analyzed by assembling models in a semi-adjustable articulator. An orofacial evaluation was performed by applying myoscanoplasty, dynamometry, and electromyography, and an evaluation of postural alignment and stability was performed using the Romberg index and plantar pressures with baropodometry. Results: In the polysomnography, 132 minutes of MOR stage and 265 of NMOR, 56 events of SB / hour, 86 micro-awakenings, 11 hypopneas, a cardiac rate of 67 l / min, and an oximetry of 95% were recorded. In the mastication, there was activity marked in masseters (Right: 330 uV Left: 452 uV) and temporary Right: 418 uV and asymmetry of temporal (34%) and orbicular (33%). There was a decrease in the contractile force of the masseter (0.3 lb) and compressive force of the orbicular (2.0 lb). Myositis was registered in the orofacial and neck muscles. There was postural involvement of left hemibody, stability during static bipedal position with Romberg Index of 0.99, and greater plantar pressure in the left foot of 68.5% than in the right foot of 31.5. Conclusions: In a case of SB diagnosed by polysomnography, there were alterations of the stomatognathic system at the dental, TMJ, and muscular levels with postural alterations and plantar pressure.

El promedio de la actividad muscular durante la masticación de los maseteros fue (D: 86) (I: 520). El promedio de la actividad muscular durante la masticación de los temporales fue (D: 340) (I: 510). El promedio en los episodios de hipopnea fue de (28,9). El promedio de oximetría fue (NMOR: 93,5) (MOR: 93,8). El promedio de la tasa cardiaca fue (NMOR: 65,4) (MOR: 66,8) latidos/minuto. El promedio de eventos de bruxismo fue (NREM: 135,4) (REM: 120,2).y el índice (eventos BS/hora) (40,60). Las características de las musculares masticatorias y los signos vitales durante el sueño de los sujetos con BS pueden ayudar al entendimiento y a la toma de decisiones en el tratamiento.

ABSTRACT: The objective of the study was to describe the average oximetry, heart rate, and apnea events values during sleep, and the activity of masseter and temporal muscles in a group of young adults with SB (Sleep Bruxism). This serial case and observational descriptive study comprised of a sample of 20 young people between 21 and 25 years of age, who were diagnosed with SB through a polysomnography test. Electromyography recordings served to describe the activity conditions of masseter and temporal muscles, while polysomnography was used to obtain measurement values and vital signs. A descriptive statistical analysis accounting for measures of central tendency, absolute and relative frequencies was performed. During mastication, the average masseter and temporal muscle activity values registered at (D: 86) (I: 520), and (D: 340) (I: 510) respectively. While, the average value for hypopnea episodes was (28.9), and (NREM: 93.5) (REM: 93.8) for oximetry. The average heart rate exhibited a value of (NREM: 65.4) (REM: 66.8) beats / minute, while the values for bruxism events registered at (NREM: 135.4) (REM: 120.2) with an index value of (SB events / hour) (40.60). Muscles of mastication characteristics, and vital signs during sleep for subjects with SB can aid in understanding and decision making in treatment.

Study on the correlation between the mandibular masticatory muscle movement and sleep tooth wear / 华西口腔医学杂志

OBJECTIVE@#To investigate the correlation between the clinical diagnostic criteria of sleep bruxism and the frequency of mandibular movements during sleep.@*METHODS@#Video polysomnography was used to record 20 healthy adults with at least one of the following clinical symptoms and signs: 1) report of frequent tooth grinding; 2) tooth wear and dentin exposure with at least three occlusal surfaces; 3) masticatory muscle symptoms in the morning; 4) masseter muscle hypertrophy. The rhythmic masticatory muscle activity (RMMA) and isolated tonic activity were scored to compare the correlations with clinical symptoms and signs. Finally, the incidence of temporomandibular disorders (TMD) was investigated in patients with isolated tonic and RMMA subjects.@*RESULTS@#Among the 20 subjects, RMMA events were observed (5.8±3.1) times·h⁻¹ and isolated tonic episodes were observed (2.1±0.9) times·h⁻¹. The frequency of RMMA events was significantly greater in the patients with acoustic molars than in those without (P<0.05). Similarly, the frequency of RMMA events was significantly greater in the patients with tooth attrition than in those without (P<0.05). However, no difference was observed between the occurrence of RMMA and the symptoms of masticatory muscles or masseter hypertrophy in the morning. The incidence of TMD was significantly higher in the patients with RMMA than in the isolated tonic patients.@*CONCLUSIONS@#The clinical symptoms and signs often used to diagnose sleep bruxism are different clinical and physiological mandibular movements during sleep. RMMA during sleep can reflect the occurrence of tooth attrition and the high risk of TMD.

Association of gender, oral habits, and poor sleep quality with possible sleep bruxism in schoolchildren

Abstract The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents' perception of children's behavior, and children's oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regression were performed and the level of significance was set at 5%. A total of 1,554 parents of children aged 8 to 10 years participated in this study. Possible sleep bruxism was reported as mild for 65.7%, moderate for 25.3%, and severe for 9% of the children. In the adjusted multinomial logistic regression, boys were 79% more likely to have sleep bruxism (OR: 1.79; 95%CI 1.23-2.60) and were 2.06 more times at risk of being in the habit of lip biting (OR: 2.06; 95%CI 1.26-3.37). Children with possible severe sleep bruxism were 61% more likely to develop object biting (OR: 1.61; 95%CI 1.09-2.39), 52% more likely to have headaches (OR: 1.52; 95%CI 1.01-2.28), and 3.29 more times at risk of poor sleep quality (OR: 3.29; 95%CI 2.25-4.82). Based on the report, boys with lip and object biting habits, headaches, and poor sleep quality presented a higher chance of possible severe sleep bruxism.
