Influência da qualidade das próteses totais na prevalência de disfunção temporomandibular / Influence of quality of total prostheses on the prevalence of temporomandibular disorder

Introduction Temporomandibular disorder (TMD) involves the mastication and temporomandibular articulation muscles. Completely toothless patients with prostheses should be thoroughly assessed since edentulism causes damage that can lead to TMD onset. Objective This study aims to assess the effect of the technical quality of total prostheses (TPs) on TMD occurrence in patients with bimaxillary TPs. Material and method 154 patients responded to a questionnaire to obtain personal data, information regarding prostheses, anamnestic index for TMD, and the prosthesis quality index. Result Of the 154 patients examined, 64 (41.6%) had no TMD, 61 (39.6%) had mild TMD, 23 (14.9%) moderate, and only 6 (3.9%) showed severe TMD. As for the quality of total prosthesis, 78 (50.6%) completely toothless individuals had satisfactory TPs while 76 (49.4) presented unsatisfactory prostheses. Regarding the time using total prosthesis, around 50% of individuals with up to 10 years use presented some degree of TMD and 70% of individuals with over 10 years presented TMD. Conclusion Considering the methodology used and the population studied, we conclude that the quality of the TPs did not influence the incidence of TMD.

Introdução A disfunção temporomandibular (DTM) é uma desordem que envolve os músculos da mastigação e da articulação temporomandibular. Pacientes desdentados totais e que utilizam protéses requerem uma avaliação criteriosa, já que o edentulismo leva a prejuízos que podem contribuir para o aparecimento de DTM. Objetivo O objetivo deste presente estudo foi avaliar o efeito da qualidade técnica das próteses totais (PTs) na incidência de DTM em pacientes portadores de PTs bi-maxilares. Material e método Foi aplicado um questionário a 154 pacientes contendo os dados pessoais, o histórico das próteses, o índice anamnésico para DTM e o índice de qualidade de prótese. Resultado Dos 154 pacientes examinados, 64 (41,6%) estavam livres de DTM, 61 (39,6%) possuíam DTM leve, 23 (14,9%), moderada e apenas 6 (3,9%) mostravam DTM severa. Quanto à qualidade da prótese total, 78 (50,6%) desdentados totais portavam PTs satisfatórias e 76 (49,4) estavam com próteses insatisfatórias. Quanto ao tempo de uso da prótese total, cerca de 50% dos indivíduos com até 10 anos de uso apresentaram algum grau de DTM e 70% dos indivíduos com mais de 10 anos acusaram a presença de DTM. Conclusão Considerando-se a metodologia empregada e a população estudada, pôde-se concluir que a qualidade das PTs não influenciou na presença de DTM.

Asociación entre Hiperlaxitud Articular Generalizada y Chasquidos de la Articulación Témporo Mandibular / Association between generalized joint hypermobility and temporomandibular joint clicking

Resumen El objetivo del estudio fue analizar si la hiperlaxitud articular generalizada (HAG) es un factor de riesgo para los trastornos de la articulación temporomandibular (ATM). Para ello se evaluó la posible asociación entre chasquido de la ATM y el diagnóstico de HAG. Se trabajó con la siguiente hipótesis: el paciente con HAG, tendría mayor prevalencia de chasquido a nivel de la ATM que los que no la presentan, constituyendo la HAG un factor de riesgo para padecer un desorden articular (DA). Se examinaron 214 estudiantes de facultad de odontología (FO) de la Universidad de la República (Udelar) de Uruguay, 161 participantes del sexo femenino y 53 masculino, de entre 18 y 30 años (edad media 23.8 años, DE=2.7). A cada participante se le realizó un cuestionario y un examen clínico para diagnóstico de HAG utilizando el índice de Beighton (IB), chasquido, antecedente de trauma maxilofacial, ortodoncia, dentición completa, bloqueo abierto y turno. Todos los exámenes fueron realizados por un investigador ciego calibrado (calibración interoperador chasquido kappa= 0.68; intraoperador Beighton=0.82, chasquido=1). El estudio fue aprobado por el Comité de Ética y todos los participantes firmaron un consentimiento informado. El análisis estadístico de los datos fue realizado en base a un modelo de regresión logística múltiple. La prevalencia de HAG fue 34.16% en el género femenino y 7.55% en el masculino, de chasquido 24.22% para el femenino y 11.32% en el masculino. Las variables género (OR=3,244, p-valor 0,018) y antecedente de traumatismo (OR=2,478, p-valor 0,041) se asociaron significativamente a la presencia de chasquido. No se encontró asociación entre chasquido e HAG. El género femenino y los antecedentes de traumatismo podrían ser factores de riesgo para desórdenes a nivel de la ATM. La ausencia de asociación entre HAG y chasquido en dicho grupo etario (18-30 años), sugiere que dicho factor podría no ser de riesgo para el desarrollo de dichas patologías.

Resumo O objetivo do estudo foi examinar se a hiperlaxidade articular generalizada (HAG) é um fator de risco para disfuncao articulacao temporomandibular (DAT). Isso foi feito avaliando a possível associação entre cliques atm e diagnóstico hag. O trabalho foi feito com a seguinte hipótese: o paciente com HAG, teria maior prevalência de clique no nível atm do que aqueles que não o fazem, tornando a HAG um fator de risco para DAT. Foram examinados 214 alunos de Odontologia da Universidad de la República (Udelar) do Uruguai, 161 do sexo feminino e 53 do sexo masculino, com idade entre 18 e 30 anos (idade média de 23,8 anos, DE:2,7). Cada participante recebeu questionário e exame clínico para diagnóstico de HAG utilizando o índice Beighton (IB), clique, antecedente de trauma maxilofacial, ortodontia, dentição completa, bloqueio aberto e turno. Todos os testes foram realizados por um pesquisador cego calibrado (calibração interoperadora kappa-click-0,68; intraoperador Beighton-0.82, clique-1). O estudo foi aprovado pelo Comitê de Ética e todos os participantes assinaram consentimento informado. A análise estatística dos dados foi realizada com base em um modelo de regressão logística múltipla. A prevalência de HAG foi de 34,16% no sexo feminino e 7,55% no masculino, de clique 24,22% para o feminino e 11,32% para o masculino. As variáveis de gênero (OR-3.244, valor p 0,018) e antecedente do trauma (OR-2.478, valor p 0,041) estiveram significativamente associadas à presença de clique. Não foi encontrada associação entre clique e HAG. O sexo feminino e o histórico de trauma podem ser fatores de risco para distúrbios no nível do articulacao temporomandibular . A ausência de associação entre HAG e click sugere que esse fator pode não estar em risco para o desenvolvimento de tais patologias.

Abstract This study analyzes whether generalized joint hypermobility (GJH) is a risk factor for temporomandibular joint disorders (TMD). Therefore, we evaluated the potential association between TMD clicking and GJH diagnosis. We worked with the following hypothesis: patients with GJH would have a higher prevalence of TMJ clicking than those without it, making GJH a risk factor for joint disorders. Two hundred and fourteen students from the School of Dentistry of Universidad de la República del Uruguay (UdelaR) were examined: 161 female and 53 male, aged 18 to 30 (average age: 23.8 years, SD=2.7). Each participant was given a questionnaire, and a clinical examination was performed to diagnose GJH using the Beighton score (BS), clicking, history of maxillofacial trauma, orthodontics, full dentition, open lock, and shift. A calibrated blind researcher (kappa inter-rater click calibration = 0.68; intra-rater BS score=0.82, click=1) performed all the examinations. The Ethics Committee approved the study, and all the participants signed an informed consent. A multiple logistic regression model was used to analyze the data statistically. GJH prevalence was 34.16% in women and 7.55% in men; clicking prevalence was 24.22% in women and 11.32% in men. There was a significant association between sex (OR=3.244, p-value 0.018) and history of trauma (OR=2.478, p-value 0.041) and the presence of clicking. No association was found between clicking and GJH. Female sex and history of trauma could be risk factors for TMJ disorders. The lack of association between GJH and clicking in this age group (18-30) suggests that GJH may not be a risk factor for developing these pathologies.

Impacto da alteração de dimensão vertical na disfunção temporomandibular: revisão integrativa / Impact of vertical dimension change on temporomandibular dyfunction: integrative review

Introdução:A Disfunção Temporomandibular (DTM) é uma condição bastante frequente na população mundial e a identificação de fatores causais, junto ao seu tratamento é de suma relevância para a qualidade de vida dos indivíduos.Objetivo:Objetivou-se por meio de uma revisão integrativada literatura de todos os tipos de estudos, avaliar se a alteraçãode dimensão vertical impacta no aparecimento das disfunções temporomandibulares.Método:As estratégias de busca foram realizadas nas bases de dados "Cochrane Library", "MEDLINE", "Web of Science", "Scopus", "LILACS", "Scielo" e "Google Acadêmico", utilizando os seguintes descritores e/ou palavras: "Temporomandibular Joint Disorders"; "Craniomandibular Disorders"; "Occlusion Vertical Dimension"; "Occlusion Vertical Dimensions"; "Vertical Dimension of Occlusion"; "Vertical Dimension".Resultados:Um total de 4 artigos foram incluídos nesta revisão.A maioria dos estudos demostram que na presença de uma DVO diminuída, o sistema estomatognático é capaz de adaptar-se, não provocando o aparecimento de DTM.Conclusões:Como conclusão, os resultados indicam que não há evidência científica suficiente que permita afirmar que a perda de dimensão vertical predispõe ao aparecimento de sinais e sintomas relacionados à disfunção temporomandibular (AU).

Introduction:TemporomandibularDysfunction (TMD) is a very frequent condition in the world population and the identification of causal factors, along with its treatment, is extremely relevant to the quality of life of the individuals.Objective:The aim of this study was to integrativereview the literature of all types of studies to assess whether loss of vertical dimension has an impact on the appearance of temporomandibular disorders.Methods:The search strategies were performed in the Cochrane Library, Medline, Web of Science, Scopus, Lilacs, Scielo and Google Scholar databases using the following descriptors and / or words : "Temporomandibular Joint Disorders"; "Craniomandibular Disorders"; "Occlusion Vertical Dimension"; "Occlusion Vertical Dimensions"; "Vertical Dimension of Occlusion"; "Vertical Dimension". Results:A total of 4 articles were included in this review. Most of the studies show that in the presence of a reduced OVD, the stomatognathic system is able to adapt, not provoking the appearance of TMD. Conclusions:In conclusion, the results indicate that there is insufficient scientific evidence to show that the loss of vertical dimension predisposes to the appearance of signs and symptoms related to temporomandibular dysfunction (AU).

Achados audiológicos em pacientes portadores de disfunção temporomandibular / Audiological findings in patients with temporomandibular dysfunction

RESUMO Objetivo Analisar os achados audiológicos em indivíduos com desordem temporomadibular e comparar esses achados com indivíduos sem desordem temporomanbibular. Métodos A amostra foi composta por 39 participantes adultos, de ambos os gêneros, com diagnóstico prévio de desordem temporomandibular (grupo de estudo) e 39 participantes adultos, sem desordem temporomandibular (grupo controle). Todos os participantes foram submetidos à audiometria tonal limiar em altas frequências, imitanciometria e pesquisa das emissões otoacústicas evocadas por produto de distorção. Resultados Observou-se prevalência de desordem temporomandibular no gênero feminino e a média de idade ficou acima da quarta década de vida. Na audiometria tonal limiar, foi observada ocorrência de perda auditiva do tipo neurossensorial e condutiva, no grupo de estudo, além de piores limiares auditivos em altas frequências. Em ambos os grupos, houve maior ocorrência de curva timpanométrica do tipo A, bem como diferenças entre os grupos na pesquisa do reflexo acústico ipsilateral e contralateral e no registro das emissões otoacústicas evocadas por produto de distorção. Conclusão Indivíduos com desordem temporomandibular apresentam piores resultados nos limiares auditivos, na timpanometria, nos reflexos acústicos ipsilaterais e contralaterais e nas emissões otoacústicas evocadas, quando comparados com o grupo controle.

ABSTRACT Purpose To analyze the audiological findings in individuals with temporomandibular disorder and compare these findings with individuals without temporomandibular disorder. Methods The sample was composed by 39 adult participants, both genders, with previous diagnosis of temporomandibular disorder (study group) and 39 adult participants, without temporomandibular disorder (control group). All the participants were submitted to audiometry including high frequencies, Immittance acoustic (Tympanometry and contralateral acoustic reflexes) and distortion product evoked otoacoustic emissions. Results The prevalence of temporomandibular disorder on female gender was observed, average age was over forty years old. In the audiometry, it was observed the incidence of hearing loss of a sensorineural and conductive type in the Study Group, besides worst hearing thresholds in high frequencies. In both groups, there was a bigger incidence of a type A tympanometric curve, as well as there were differences between the groups in the research of the ipsilateral and contralateral acoustic reflex and in the recording of distortion product evoked otoacoustic emissions. Conclusion It's possible to conclude that individuals with temporomandibular disorder show worst results in the hearing thresholds, in the tympanometry, in the ipsilateral and contralateral acoustic reflexes, in the evoked otoacoustic emissions, when compared to the control group.

Clinical and sociodemographic characterization of patients with temporomandibular dysfunction of the University Hospital of Maracaibo

Objective: To describe the clinical and sociodemographic characteristics of patients with temporomandibular joint ( TMJ) dysfunction at the University Hospital of Maracaibo. Methods: A retrospective study was conducted by assessing the clinical history of patients with TMJ dysfunction who underwent orthopedic treatment in the Oral Surgery Unit of the Dentistry Service of the University Hospital of Maracaibo. Information was collected on socio-demographic characteristics (age, gender, origin, and occupation) and clinical findings related to the presence, location, area, beginning, frequency, cause, and duration of pain, and signs present during mandibular dynamics; additionally, a structural and functional diagnosis was made. The data were processed and analyzed using SPSS v.9. Results: 221 patients were included, with only 10% of the disorders observed in males. Regarding occupation, 39.1% worked at home and 28.3% were students. 97.2% of patients presented pain, and of these, pain was localized in 75%. During mandibular movement with maximum opening, 47.4% showed some difficulty, which was more significant in males. TMJ noises were noted in 74.9%, more often in females. In addition, the previous partial displacement of a disk with recapture presented an incidence of 66.4%. Conclusion: The prevalence of TMJ dysfunction was higher in female patients and in adulthood. Noises were present with a high frequency, as was limited mandibular movement.

Alteraciones propioceptivas en pacientes posterior a la extracción del tercer molar / Proprioceptive alterations in patients after the third molar extraction

Introducción: la propiocepción informa al organismo de la posición de los músculos, regulando la dirección y el rango del movimiento, de ahí la importancia de la intervención médica en función de mejorar indicadores de salud relacionados con ella. Objetivo: identificar por medio de la aplicación del test de Fukuda, la variación de la propiocepción, posterior a la extracción del tercer molar. Métodos: el estudio se realizó en los meses de julio-agosto de 2015, en el área de cirugía maxilofacial del Hospital Pablo Arturo Suárez, República del Ecuador. La investigación fue de tipo exploratoria, prospectiva, observacional y longitudinal. Se estudió una muestra de 30 pacientes entre 16 a 56 años, de los cuales 13 eran hombres y 17 mujeres. Los criterios de inclusión fueron que tuviesen al menos dos terceros molares, uno a cada lado en la parte inferior mandibular, y que no presentasen afecciones vestibulares, otitis y alteraciones en la propiocepción por enfermedades del sistema nervioso. Resultados: se comprobó que existe una diferencia significativa (p< 0,013) en el desplazamiento motor de los sujetos sometidos a estudio después de la extracción de los terceros molares, pero no existe una diferencia significativa en los grados de los giros corporales (p< 0,62). Conclusiones: la mala posición de los terceros molares puede alterar la propiocepción; por consiguiente, la extracción de estos disminuye las alteraciones propioceptivas, especificamente el desplazamiento longitudinal como variable significativa, y las desviaciones en grados de los giros corporales como no significativas(AU)

Introduction: proprioception informs the organism about the position of the muscles, regulating the direction and range of movement, hence the importance of medical intervention in terms of improving health indicators related to it. Objective: to identify, by means of the application the Fukuda test, the variation of proprioception, after the third molar extraction. Methods: the study was conducted in the months of July and August 2015, in the area of maxillofacial surgery of Pablo Arturo Suárez Hospital, Republic of Ecuador. The research was exploratory, prospective, observational and longitudinal. A sample of 30 patients aged 16-56 years old was studied, of which 13 were men and 17, women. The inclusion criteria were that they had at least two third molars, one on each side in the mandibular lower part, and that they did not present vestibular affections, otitis, and alterations in proprioception due to diseases of the nervous system. Results: asignificant difference (p< 0.013) was found in the motor displacement of the subjects under study after the third molars extraction, but there is no significant difference in the degrees of body turns (p< 0.62). Conclusions: the bad position of third molars can alter proprioception; consequently, the extraction of these decreases proprioceptive alterations, specifically the longitudinal displacement as a significant variable, and the deviations in degrees of the body turns as non-significant(AU)

Los trastornos temporomandibulares (TTM) son una serie de signos y síntomas buco faciales de etiología multifactorial. En Cuba existen varias investigaciones que tratan sobre los TTM sobre todo en jóvenes dentados no conociéndose amplias referencias de este tipo de estudio en el adulto mayor. Objetivo: identificar la prevalencia de TTM en los adultos mayores institucionalizados, los signos y síntomas más frecuentes según edad y sexo. Métodos: se realizó un estudio descriptivo transversal en 113 adultos mayores de ambos sexos, institucionalizados en dos hogares de ancianos de la Habana, de marzo a abril de 2012. Se aplicó una encuesta donde se recogió sexo, edad, signos y síntomas. Las manifestaciones clínicas evaluadas fueron: la presencia de dolor muscular, dificultad al movimiento de abertura y cierre, dolor articular, dolor muscular articular, ruidos articulares, limitación de la abertura bucal, limitación de los movimientos de lateralidad y propulsión, desviación de la mandíbula. Resultados: el 40,70 por ciento de los adultos mayores estudiados, presentaron afectación en la articulación temporomandibular. Los ruidos articulares fue el síntoma con mayor predominio en todos los grupos etarios (76,08 por ciento), afectando al 82,35 por ciento de los hombres y al 72,41 por ciento de las mujeres. Seguido por el dolor muscular que se manifestó en el 52,17 por ciento de los afectados, con mayor porcentaje en mujeres (58,62 por ciento) que en hombres (41,17 por ciento). La dificultad para realizar los movimientos de abertura y cierre se detectó en el 28,26 por ciento de los afectados con mayor prevalencia en el sexo femenino (34,48 por ciento) que en el masculino (17,14 por ciento). Conclusiones. se observó una elevada prevalencia de TTM en los adultos mayores estudiados. Los signos y síntomas más frecuentes por edad y sexo fueron los ruidos articulares y el dolor muscular y la dificultad para realizar los movimientos de abertura y cierre(AU)

The Temporomandibular Disorders (TMD) are a series of signs and symptoms of multifactoral etiology in the mouth-face area. In Cuba, there exist several research studies about TMD, mainly in young people with natural dentition, but no extensive references of this kind are known in the older adult. Objective: to identify the prevalence of temporomandibular disorders in the institutionalized older adults in two homes for the elderly located in Havana from March to April 2012. A survey was administered in which sex, age, sign and symptoms data were collected. The evaluated clinical manifestations were muscular pain, difficult opening and closure movement, joint pain, articular and muscular pain, articulary noises, limited mouth opening, limited laterality and propulsion movements, jaw deviation. Methods: a descriptive and cross-sectional study of 113 institutionalized older adults of both sexes was carried out from March to April of 2012 in two homes for elderly in Havana. A survey was administered in which sex, age, sign and symptoms data were collected. The evaluated clinical manifestations were muscular pain, difficult opening and closure movement, articular pain, articular and muscular pain, articular noises, limited mouth opening, limited laterality and propulsion movements, jaw deviation. Results: in the studied older adults, 40.70 percent were affected in their temporomandibular articulation. The articular noises were the most prevalent sign in all age groups (76.08 ), affecting 82.35 percent of men and 72.41 percent of women, followed by muscular pain in 52.17 percent of those affected, with higher percentage found in women (58.62 percent) than in men (41.17 percent). Difficulties in opening and closing the mouth were detected in 28.26 percent of the affected people, being more prevalent in females (34.48 percent) than in males (17.14 percent). Conclusions: a high prevalence of TMD was observed in the studied older people. The most frequent symptoms and sings by age and sex were articular noises and the muscular pain, and the difficulty in making the opening and closing movements of the mouth(AU)
