Tooth Bleaching: A bibliometric analysis of the top 100 most-cited papers

Abstract This study analyzes the characteristics of the top 100 most-cited papers related to tooth bleaching. A literature search was performed on the Web of Science up to March 2022. The number of citations was cross-matched with the citation count on Scopus and Google Scholar. The following data were collected: number and density of citations; authorship; year and journal of publication; study design and thematic; keywords; institution and country of origin. Spearman's correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The VOSviewer software was used to generate collaborative network maps for the authors and keywords. The number of citations ranged from 66 to 450. Papers were published between 1981 and 2020. The most frequent study design and topic were laboratory-based studies and 'interaction of the bleaching agent with dental tissues', respectively. Cochran M, Loguercio AD, Matis B, Reis A, and Suliman M were the authors with the highest number of papers. The countries with the most papers were the United States of America (USA) (28%) and Brazil (20%). Indiana University and State University of Ponta Grossa were the institutions with the most papers (6% each). There was a very strong correlation among the number of citations of the three databases. The 100 most-cited papers related to tooth bleaching were mainly published by the USA and Brazil, with laboratory-based studies addressing topics related to the effects of bleaching agents on tooth structure being the most prevalent.

Parental acceptance toward behavior guidance techniques for pediatric dental visits: a meta-analysis

Abstract This study aimed to answer the following question: What is the proportion of acceptance reported by parents toward pediatric behavior guidance techniques (BGTs)? Observational studies that evaluated parental acceptance of BGTs during pediatric dental visits among parents of non-special health care need (non-SHCN) and SHCN children were included. A search of the Cochrane Library, Latin American and Caribbean Health Sciences (LILACS), MedLine/PubMed, PsycINFO, Scopus, and Web of Science databases, in addition to gray literature, was performed until October 2021. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment. The certainty of evidence was assessed using the Recommendation, Assessment, Development, and Evaluation (Grade). Fifty-three studies with 4868 participants were included, and 42 were retained for the random-effects proportion meta-analysis. The methodological quality varied from low to high. The agreement with the BGTs varied from 85.6% (95%CI: 77.5-92.1; p < 0.001; I 2 = 93.6%; 16 studies; n = 1399) for tell-show-do to 25.7% (95%CI: 17.8-34.4; p < 0.001; I 2 = 90.4%; 12 studies; n = 1129) for passive protective stabilization among non-SHCN children's parents; meanwhile, among the parents of SHCN children, it varied from 89.1% (95%CI: 56.1-99.7; p < 0.001; I 2 = 95.7%; 3 studies; n = 454) for tell-show-do to 29.1% (95%CI: 11.8-50.0; p = 0.001; I 2 = 84.8%; 3 studies; n = 263) for general anesthesia. The effect estimates varied greatly, as substantial heterogeneity across studies was observed, thus limiting the confidence in the results. Parents were more likely to agree with basic BGTs over advanced BGTs, with very low certainty of evidence. Dentists should discuss BGT options with parents. Protocol registration: PROSPERO CRD42018103834.

Endodontic therapy in primary teeth: a bibliometric analysis of the 100 most-cited papers

Abstract: The purpose of this review was to identify and analyze the main characteristics of the 100 most-cited papers in the field of endodontic therapy in primary teeth. A search for the most-cited articles was conducted in the Clarivate Analytics Web of Science 'Core-Collection' (WoS-CC) database up to December 2020. Papers were ranked in descending order, by number of citations, and each paper was matched with the citation count on Scopus and Google Scholar. Two independent reviewers selected the most-cited papers and analyzed it according to the number and density of citations, year and journal of publication, authors, countries and contributing institutions, study design, topic of the paper, and keywords. Spearman's correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The citation count varied from 15 to 135 (WoS-CC), 8 to 141 (Scopus), and 14 to 317 (Google Scholar). Of the 306 contributing authors, most paper contributions were from Sakai VT, Oliveira TM, and Machado MAAM (5 each). Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and "pulpotomy" was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.

Em 11 dos 15 estudos incluídos, os pais tinham preferência pelos médicos que utilizavam jaleco (73,3% [IC95% 67,9-78,6]; p=0,11). Conclusões: Com uma qualidade baixa de evidência, crianças e pais preferem os médicos que usam jaleco branco.

Influence of the method for determining working length on the obturation level of primary molars

Abstract Efficient working length determination is essential for a successful endodontic treatment. The purpose of the present study was to evaluate whether the method for determining the working length of root canals (radiographic or electronic) influences the obturation level of primary molars. Thus, a controlled, triple-blind, randomized clinical trial was conducted. Sixty-four children aged 6 to 9 years with an indication for primary molar pulpectomy were included. Participants were divided into two groups according to the method used to determine the working length of the root canals: (G1) radiographic and (G2) using an electronic apex locator. The study had 3 operators: #1 performed the clinical procedures, except the electronic measurement; #2 performed radiographic measurement and final evaluation of obturation level; and #3 performed eligibility criteria and electronic measurement. Adequacy of obturation level was evaluated based on the final conventional radiography and it was recorded as acceptable or unacceptable (short or overfilled). Data were analyzed with repeated measures logistic regression. There was no difference between the obturation level of primary molars measured by radiographic and electronic methods (p > 0.05). The other investigated variables (age, tooth type, dental arch position, last instrumentation file, and canal location) also did not influence the obturation level (p > 0.05). In conclusion, both measurement methods resulted in similar adequacy of obturation level in primary molars after pulpectomy.

Influência do banda-alça na manutenção de espaço do arco inferior após a perda precoce de molares decíduos: um estudo piloto / Influence of loop band on mandibular arch space maintenance after early loss of deciduous molars: a pilot study

Objetivo: Avaliar a influência do dispositivo banda-alça na perda de espaço após exodontia precoce de molares decíduos inferiores em escolares, em um período de 3 meses. Materiais e métodos: Trata-se de um estudo piloto de ensaio clínico randomizado, com dois grupos paralelos. A amostra incluiu 25 crianças, entre 6 e 9 anos, com indicação clínica e radiográfica de exodontia unilateral de um molar decíduo inferior. Estes foram divididos em Grupo Controle (G1): sem intervenção; e Grupo Intervenção (G2): com instalação de banda-alça. Todos os pacientes foram moldados antes do procedimento de exodontia (T1) e no acompanhamento de 3 meses (T2). Um avaliador cego quanto aos grupos e tempo realizou as medidas estabelecidas nos modelos de gesso. A análise estatística foi realizada por meio dos testes T pareado e T de Student nos casos de distribuição normal dos dados e testes não-paramétricos Wilcoxon e Mann-Whitney para distribuição não normal. Resultados: Todos os participantes foram classificados como Classe I, com overjet de até 3mm e padrão facial mesocéfalo. A maioria (64%) teve o segundo molar decíduo perdido. Após 3 meses, o G1 perdeu, em média, 0,75mm a mais na distância linear do espaço de extração comparado ao G2 (P<0,05). Conclusão: Concluiu-se que, embora os dois grupos apresentaram perda de espaço, o G1 (sem intervenção) apresentou uma perda de espaço maior no período de acompanhamento de 3 meses.

Objective: To evaluate the influence of the band and loop space maintainer on space loss after the early extraction of mandibular primary molars in schoolchildren, over a period of 3 months. Materials and Methods: a pilot study of a randomized clinical trial was carried out, with two parallel groups. The sample included 25 children, aged between 6 and 9 years, with clinical and radiographic indication for unilateral extraction of a mandibular primary molar. The patients were divided into Control Group (G1): with no intervention; and Intervention Group (G2): with the installation of the space maintainer. A dental cast was obtained before the extraction procedure (T1) and at the 3-month followup (T2). An evaluator, blinded to the groups and time, performed the established measures in the dental casts. Statistical analysis was performed using Paired Sample T test and Student's T test in cases of normal data distribution, and nonparametric Wilcoxon and Mann-Whitney tests for non-normal distribution. Results: All participants were classified as Class I, with an overjet of up to 3 mm and a mesocephalic facial pattern. The majority (64%) had a lost second deciduous molar. After 3 months, the G1 lost, on average, 0.75mm more in the linear distance from the extraction space (P<0.05). Conclusion: It was concluded that, although the two groups showed space loss, G1 (without intervention) showed a greater loss of space in the 3-month follow-up period.

Associação entre problemas para dormir e condições orais em escolares / Association between trouble sleeping and oral conditions among schoolchildren

ABSTRACT Objective: To investigate the prevalence of self-reported trouble sleeping due to dental problems and its association with oral conditions in schoolchildren. Methods: This is a cross-sectional study carried out with a representative sample of 1,589 schoolchildren aged 8-10 years enrolled in public schools from Florianópolis, Santa Catarina, Brazil. Non-clinical data included a questionnaire about socioeconomic indicators answered by parents/guardians. Children were questioned about whether they had trouble sleeping due to dental problems and about previous history of toothache. Clinical oral examinations were performed to evaluate dental caries - Decayed, Missing, and Filled Teeth Index (DMFT/dmft index) and its clinical consequences [PUFA/pufa index: considering the presence of pulpal involvement (P/p); ulceration of tissues due to tooth fragments from decayed crowns (U/u); fistula (F/f); and abscesses (A/a), and traumatic dental injuries (TDI)]. We conducted a descriptive analysis and used adjusted logistic regression models (p<0.05; 95%CI). Results: The prevalence of trouble sleeping due to dental problems was 28%. Children with untreated dental caries (OR 1.32; 95%CI 1.05-1.67) and clinical consequences from the PUFA/pufa index (OR 1.89; 95%CI 1.45-2.46) had higher chances of reporting trouble sleeping due to dental problems. Conclusions: Approximately one-third of the children declared having trouble sleeping due to dental problems. Untreated dental caries and its clinical consequences were associated with self-reported trouble sleeping due to dental problems in schoolchildren.

RESUMO Objetivo: Investigar a prevalência de problemas para dormir por motivos dentários autorrelatado e sua associação com condições orais adversas em escolares. Métodos: Estudo transversal com amostra representativa de 1589 escolares de 8 a 10 anos matriculados em escolas públicas de Florianópolis, Brasil. Os dados não clínicos incluíram um questionário sobre indicadores socioeconômicos respondidos pelos pais/cuidadores. As crianças foram questionadas se tinham problemas para dormir por motivos dentários e sobre episódios anteriores de dor de dente. Foram realizados exames clínicos orais para avaliar: cárie dentária - Índice de Dentes Cariados, Perdidos e Obturados (índice CPO-D/ceo-d) - e suas consequências clínicas (índice PUFA/pufa - presença de envolvimento pulpar (P/p); ulceração (U/u); fístula (F/f); e abscessos (A/a) e traumatismo dental (TD). Foram realizados análise descritiva e modelos ajustados de regressão logística (p<0,05; IC95%). Resultados: A prevalência de problemas para dormir por motivos dentários foi de 28%. Crianças com cárie dentária não tratada (OR 1,32; IC95% 1,05-1,67) e presença de índice PUFA/pufa (OR 1,89; IC95% 1,45-2,46) apresentaram maiores chances de relatar problemas para dormir devido a razões dentárias. Conclusões: Aproximadamente, um terço das crianças apresentou problemas para dormir devido a razões dentárias. Cárie dentária não tratada e suas consequências clínicas foram associadas a problemas autorrelatados para dormir por motivos dentários em escolares.

The perception of caregivers of poor oral health of their children and its related clinical conditions / Percepção de cuidadores sobre a má saúde bucal das crianças e sua relação com condições clínicas

ABSTRACT Objective: To determine the association between the perception of caregivers regarding the oral health of their children and socio-demographic characteristics, report of dental pain, and clinical oral conditions. Methods: A cross-sectional study was conducted with 570 children aged two to five years old, enrolled at public preschools, and with their caregivers. Data regarding perceptions of oral health status in children, socio-demographic characteristics, and dental pain were collected from a questionnaire. Three examiners (Kappa>0.7) evaluated children's oral health status using the dmft index, pufa index, and the Andreasen classification for traumatic dental injury (TDI). The occurrence of open bite and overjet was also investigated. Descriptive analyses, and unadjusted and adjusted logistic regression were used, considering a 5% significance level. Results: A total of 24.7% of children had poor oral health status, which increased 4.92-fold (95% confidence interval [95%CI] 3.05-7.93) when children had dental caries, and 3.78-fold (95%CI 1.63-8.76) when there were consequences from dental caries. The perception of poor oral health was also associated to open bite (Odds Ratio [OR] 1.98; 95%CI 1.16-3.38) and TDI (OR 1.68; 95%CI 1.06-2.68). No associations were found between the perception of caregivers and socio-demographic variables or overjet. Conclusions: The perception of caregivers of poor oral health in their children was associated to dental caries, its consequences, TDI, and open bite.

RESUMO Objetivo: Determinar a associação entre a percepção dos cuidadores sobre a saúde bucal das crianças e características sociodemográficas, relato de dor dentária e condições clínicas bucais. Métodos: Foi realizado um estudo transversal com 570 crianças de dois a cinco anos matriculadas em pré-escolas públicas e seus cuidadores. Os dados referentes à percepção do estado de saúde bucal nas crianças, características sociodemográficas e dor dentária foram coletados por meio de um questionário. Três examinadores (Kappa>0,7) avaliaram o estado de saúde bucal das crianças usando o índice ceo-d, o índice PUFA e a classificação de Andreasen para traumatismo dentário (TD). A ocorrência de mordida aberta e overjet também foi investigada. Análise descritiva e regressão logística não ajustada e ajustada foram realizadas, considerando um nível de significância de 5%. Resultados: A percepção da má condição de saúde bucal nas crianças foi de 24,7%, a qual aumentou 4,92 vezes (IC95% ­3,05-7,93) quando as crianças apresentaram cárie dentária e 3,78 vezes (intervalo de confiança de 95% [IC95%] 1,63-8,76) quando houve consequências de cárie dentária. A percepção de saúde bucal ruim também foi associada a mordida aberta (Odds Ratio [OR] 1,98; IC95% 1,16-3,38) e TD (OR 1,68; IC95% 1,06-2,68). Não foram encontradas associações entre as percepções dos cuidadores e variáveis sociodemográficas ou overjet. Conclusões: As percepções dos cuidadores sobre a má condição de saúde bucal das crianças foram associadas à cárie dentária, suas consequências, TD e mordida aberta.

Is the perception of anxiety in dental care by children and their parents concordant? / A percepção da ansiedade no atendimento odontológico pelas crianças e por seus pais são concordantes?

ABSTRACT Objectives: This research evaluated the caregivers' perception on dental anxiety of their children and verified its association with independent variables: caregivers' dental anxiety and the reason for their last dental appointment, socioeconomic factors, caregivers and children's last dental visit, children's oral health status, dental anxiety and kind of dental appointment. Methods: Fifty-eight children aged 6 to 9 years old and their caregivers participated in the study. For this cross-sectional study the participants were selected from a clinical study where half of the children received fluortherapy and the other half tooth extraction. The caregivers answered questions about socioeconomic status and to evaluate their dental anxiety and the perception on children's dental anxiety they answered the Dental Anxiety Scale and Dental Anxiety Question, respectively. To evaluate children's dental anxiety the Modified Venham Picture Test was applied and their oral health status was verified with the DMFT index. Data were analyzed with Chi-square, Fisher's Exact and Mann-Whitney's test. Results: The frequency of the caregivers' perception on dental anxiety of their children were 50.9%. However, 41.4% of children reported dental anxiety. There was a significant difference between Dental Anxiety Question and Modified Venham Picture Test (p=0.002). There was no relationship between caregivers' perception on dental anxiety of their children and other independent variables. Conclusion: There was a significant difference between children's dental anxiety and the perception of it by those caregivers.

RESUMO Objetivos: Este trabalho avaliou a percepção dos responsáveis sobre a ansiedade odontológica das crianças e sua associação com as variáveis independentes: ansiedade odontológica dos responsáveis e o motivo para sua última consulta odontológica, fatores socioeconômicos, última visita ao dentista dos responsáveis e da criança, condição bucal da criança e tipo de procedimento odontológico realizado na consulta. Métodos: Neste estudo transversal a amostra contou com 58 crianças entre 6 e 9 anos e seus responsáveis. Os participantes foram selecionados a partir de um estudo clínico em que metade das crianças receberam fluorterapia e as outras exodontia. Os responsáveis responderam ao questionário socioeconômico e para avaliar a ansiedade odontológica e a percepção sobre a ansiedade odontológica das crianças eles responderam a Dental Anxiety Scale e a Dental Anxiety Question, respectivamente. Para avaliar a ansiedade odontológica das crianças foi aplicado o Venham Picture Test Modificado e a sua condição bucal foi verificada pelo índice CPO-D/ceo-d. A análise dos dados foi realizada pelo teste Qui-quadrado, Exato de Fisher e Mann-Whitney. Resultados: A frequência de responsáveis que perceberam a ansiedade odontológica das crianças foi de 50,9%. Entretanto, 41,4% das crianças relataram a ansiedade odontológica. Houve uma diferença significativa entre o Dental Anxiety Question e o Venham Picture Test Modificado (p = 0,002). Não houve relação entre a percepção dos responsáveis sobre a ansiedade odontológica das crianças com as demais variáveis independentes. Conclusão: Existiu uma diferença significativa entre a ansiedade odontológica das crianças e a percepção desta pelos responsáveis.

Avaliação do comportamento odontológico infantil durante procedimentos de profilaxia e exodontia / Evaluation of children's dental behavior during prophylaxis and extraction procedures

Objetivo: Avaliar o comportamento infantil durante os tratamentos odontológicos de profilaxia e de exodontia. Métodos: Este estudo transversal contou com 58 crianças, entre 6 e 9 anos de idade. Dentre essas, 29 crianças foram submetidas ao procedimento de exodontia e 29 ao procedimento de profilaxia. O comportamento infantil frente ao tratamento odontológico proposto foi avaliado por um cirurgião-dentista treinado através da versão brasileira e validada da Escala Comportamental de Venham (Venham's Behavior Rating Scale (BvVBRS). Avaliou-se também a ansiedade infantil prévia ao tratamento odontológico através da Venham Picture Test modificada (VPTm). A condição bucal foi avaliada pelo índice CPO-D e ceo-d, por pesquisador previamente calibrado (Kappa > 0,7). Os pais/responsáveis responderam a um questionário socioeconômico e questões relacionadas a experiência odontológica prévia das crianças. Realizou-se análise descritiva e teste Qui-quadrado com nível de significância de 5%. Resultados: Em relação ao comportamento o grupo submetido à profilaxia apresentou 100% das crianças com um comportamento positivo, enquanto no grupo submetido à exodontia houve 75,9% das crianças com comportamento positivo (p = 0,010). Idade, gênero e presença de ansiedade prévia aos procedimentos não tiveram relação estatisticamente significante com o comportamento infantil. A presença de cárie na dentição decídua esteve associada ao comportamento negativo durante os procedimentos odontológicos (p = 0,013). Conclusão: Foi observado que durante o procedimento de profilaxia os pacientes demonstraram um comportamento mais colaborador quando comparado ao procedimento de exodontia.

Aim:To investigate the behavior of children during dental treatments of prophylaxis and dental extraction. Methods: Fifty-eight children, 6 to 9 years of age, and their caregivers participated of this cross-sectional study. Of these, 29 children underwent prophylaxis and 29 dental extraction. Child behavior was assessed through the Brazilian version of the Venham's Behavior Rating Scale (BvVBRS), and dental anxiety was measured by the Venham Picture Test modified (VPTm). Clinical examination was performed by a calibrated examiner (Kappa > 0.7), using the decay, missing, filled index for primary and permanent dentition dmft/DMFT index. The caregivers answered a socioeconomic questionnaire and questions related to the previous dental experience of the children. Descriptive data analysis and Chi-square test were performed, with a significance level of 5%. Results:Regarding behavior, the prophylaxis group presented 100% of children with a positive behavior, while the extraction group contained 75.9% of children with positive behavior, and this difference was statistically significant (p = 0.010). Age, gender, and presence of anxiety prior to the procedures had no statistically significant relationship to the presented child behavior. The presence of caries in the deciduous dentition was associated with child behavior during dental procedures (p = 0.013). Conclusion: It was observed that the type of procedure interfered directly in the negative behavior of the children, with a difference in cooperation with invasive (dental extraction) and non-invasive (prophylaxis) procedures.

Socioeconomic Disparities in Oral Health Related Quality of Life of Schoolchildren: A Cross-Sectional Study

Abstract Objective: To analyze whether demographic and socioeconomic factors can influence the OHRQoL in schoolchildren. Material and Methods: A cross-sectional study using a representative sample of 1137 children aged 8-10 years, enrolled in public schools in Florianópolis, Brazil, was conducted. Children answered the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) quality of life questionnaire and their parents responded to socioeconomic and demographic questions. Logistic regression models were used to analyze the data. Results: Higher probability of presenting a negative impact on the OHRQoL was observed in children whose skin color was non-white (OR 1.46, 95% CI 1.04-1.69) and female (OR 1.33, 95% CI 1.04-1.69). Children in whom the head of the family had years of schooling 9-11 (p=0.001), 5-8 (p=0.005) and ≤4 (p=0.000) were more likely to have a negative impact on the OHRQoL. CPQ8-10 domains evaluation showed that variables education, gender, skin color, and age were associated with a negative impact on OHRQoL (p≤0.05). Conclusion: The educational level of the head of the family and the demographic characteristics of the children are associated with a negative impact on the OHRQoL.

Is there an association between crown discoloration and pulp necrosis in traumatized permanent teeth? A meta-analysis

Abstract The present study aimed to identify the scientific evidence regarding the association between crown discoloration and pulp necrosis in traumatized permanent teeth. A systematic literature search was conducted in the PubMed/Medline, Lilacs/BBO, Scopus, Web of Science, Cochrane Library databases, and grey literature. Quality assessment and bias control were carried out according to the Fowkes and Fulton guidelines. Meta-analysis was performed, and the odds ratio was calculated with a 95% confidence interval. The quality assessment of the evidence was determined for the meta-analysis outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. From 2,702 studies identified, five articles met the inclusion criteria. One among these showed no methodological soundness and was excluded from the meta-analysis, and the remaining four studies were included in the meta-analysis. The total number of traumatized permanent teeth evaluated in the meta-analysis was 367. The results showed a positive association between crown discoloration and pulp necrosis in permanent teeth. Teeth with crown discoloration showed 23 times more chance to present pulp necrosis than teeth without crown discoloration (OR 23.82 [1.25, 452.87]; p = 0.03), with a very low certainty of evidence. There is a significant association between crown discoloration and pulp necrosis of traumatized permanent teeth. Due to the very low strength of evidence according to GRADE, this result should be viewed with caution.

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.

Malocclusion traits and sucking habits in preschool children: a cross-sectional study

Objective: The aim was to evaluate the prevalence of malocclusion traits altogether and separate in anterior open bite, accentuated overjet and posterior cross-bite, and the possible association between them and sucking habits and breastfeeding. Methods : A preschool-based cross-sectional study was conducted with 472 children aged 24-60 months and their parents (response rate 86.6%). Three trained dentists (Kappa > 0.70) examine children for anterior open bite, accentuated overjet and posterior cross-bite and parents answered a questionnaire indicating the presence of breastfeeding, bottle usage, pacifier usage, finger sucking and the length of usage of all these habits. Results : The prevalence of malocclusion traits was 38.8%, Accentuated overjet was the most prevalent (30.3%) followed by posterior cross-bite (8.9%) and anterior open bite (7.4%). The unadjusted Poisson regression showed that children who were not breastfed had 63.0% more prevalent malocclusion traits when compared with those who were breastfed (RP 1.63, 95%CI 1.06-2.50). Length of pacifier usage in months was the only habit remained in the adjusted model associated with anterior open bite (RP 1.10, 95%CI 1.05-1.14, p < 0.000) and accentuated overjet (RP 1.03, 95%CI 1.01- .05, p = 0.004). For posterior cross-bite none habit showed association in the adjusted model. All models were adjusted for age and sex. Conclusion : Accentuated overjet is the most prevalent malocclusion trait. Length of pacifier usage is associated with the presence of malocclusion traits, anterior open bite and accentuated overjet. None of the investigated habits is associated with posterior cross-bite.

Objetivo: O objetivo foi estimar a prevalência de maloclusões avaliadas em conjunto e separadamente em mordida aberta anterior, sobressaliência acentuada e mordida cruzada posterior, e a possível associação entre elas e os hábitos de sucção e amamentação. Métodos : Estudo transversal foi realizado com 472 pré- escolares de 24 a 60 meses e seus pais (taxa de resposta de 86,6%). Três dentistas treinados (Kappa > 0,70) examinaram as crianças para mordida aberta anterior, sobressaliência acentuada e mordida cruzada posterior e os pais responderam a um questionário indicando a presença de amamentação, uso de mamadeira, uso de chupeta, sucção de dedo e tempo de hábito. Resultados : A prevalência de maloclusões foi de 38,8%. A sobressaliência acentuada foi o mais prevalente (30,3%), seguido da mordida cruzada posterior (8,9%) e da mordida aberta anterior (7,4%). A regressão de Poisson não ajustada mostrou que as crianças que não foram amamentadas apresentaram 63,0% maior prevalência de maloclusão quando comparadas com aquelas que foram amamentadas (RP 1,63, IC95% 1,06-2,50). A duração do uso de chupeta em meses foi o único hábito que permaneceu no modelo ajustado associado à mordida aberta anterior (RP 1,10, IC 95% 1,05-1,14, p < 0,000) e sobressaliência acentuada (RP 1,03, IC 95% 1,01- 1,05, p = 0,004). Para mordida cruzada posterior nenhum hábito mostrou associação no modelo ajustado. Todos os modelos foram ajustados por idade e sexo. Conclusão : A sobressaliência acentuada é a maloclusão mais prevalente. O tempo do uso de chupeta está associado à presença de maloclusão, mordida aberta anterior e sobressaliência acentuada. Nenhum dos hábitos investigados está associado à mordida cruzada posterior.

Mouth Breathing and Prevalence of Sleep Bruxism among Preschoolers aged 2 to 5 years

Objective: To determine the prevalence of bruxism, associating it with mouth breathing in preschool children in Florianopolis, Brazil. Material and Methods: Clinical examination and questions to parents/guardians of 429 children aged 2-5 were conducted. The clinical examination was performed by three calibrated examiners to register the presence of tooth wear on incisors and molars. The questions were related to sleep bruxism (teeth grinding) and mouth breathing. For determinate diagnosis, were "possible" bruxism by the American Academy of Sleep Medicine and "probable" bruxism, whereas the Item Response Theory was employed for mouth breathing. To determine the associations, a Chi-square test and Fisher exact test with a standard error of 5% and 95% interval confidence were applied. Results: The clinical examination revealed bruxism in 8.2%, whereas the parental report revealed bruxism in 17.2%. When clinical examination was associated with the parent's report, bruxism was present in 2.1%. Among the non-clinical variables, the most prevalent changes included: child presenting a regular stuffy nose (19.6%), followed by child is always open-mouthed (16.1%). A significant statistical association between bruxism and age was obtained (p<0.05), the age group with prevalence of 4 and 5 years old with 68.9%. There was no mouth breathing association with the presence of bruxism (p>0.05). Conclusion: Bruxism was prevalent for children aged 4-5 and bruxism had no association with mouth breathing.

O impacto do traumatismo dental e do comprometimento estético na qualidade de vida de pré-escolares / Impact of dental trauma and esthetic impairment on the quality of life of preschool children

RESUMO Objetivo: Avaliar o impacto do trauma dental (TD) e do comprometimento estético na qualidade de vida (QV) de pré-escolares e familiares. Métodos: Este estudo foi realizado com crianças de 2 a 5 anos em 11 pré-escolas de Florianópolis (SC), Brasil. Os pais/responsáveis preencheram a versão brasileira do questionário sobre QV Early Childhood Oral Health Impact Scales (B-ECOHIS), um questionário socioeconômico e perguntas específicas sobre TD. As crianças foram examinadas por três examinadores calibrados (kappa>0,7). O TD foi avaliado de acordo com os índices adotados pela Organização Mundial de Saúde (OMS), e o comprometimento estético também foi classificado. Os dados foram analisados descritivamente e submetidos à análise bivariada por qui-quadrado e teste de Fisher, sendo significante p<0,05. Resultados: Dos pré-escolares examinados, 62,5% foram diagnosticados com trauma e 15,6% com comprometimento estético, e somente 12% dos pais relatou que seus filhos apresentam impacto na QV. O TD não se associou a sexo, idade ou QV. A alteração de cor da coroa por TD relacionou-se ao comprometimento estético, e apenas este causou impacto negativo na QV (p<0,05) e se associou ao domínio limitações orais (p<0,05). Conclusões: O comprometimento estético causou impacto negativo na QV das crianças, e o trauma dental não se associou com a QV das crianças nem de suas famílias.

ABSTRACT Objective: To evaluate the impact of dental trauma and impaired esthetics on the quality of life (QoL) of preschool children and their relatives. Methods: Study conducted with 192 children aged 2 to 5 years in 11 preschools in Florianópolis, Santa Catarina, South of Brazil. Parents/caregivers completed a questionnaire on quality of life (Brazilian version of the Early Childhood Oral Health Impact Scales - B-ECOHIS), a socioeconomic survey, and then answered specific questions related to dental trauma. The subjects were examined by three accordant examiners (Kappa>0.7). Dental trauma was evaluated on the basis of indexes adopted by the World Health Organization, and esthetic impairment was then classified. Data were descriptively analyzed and put to bivariate analysis by chi-square and Fisher tests, with significance level at 5%. Results: The prevalence of dental trauma was 62.5% with 15.6% of esthetic impairment. Almost 12% of parents reported impact on the quality of life of their children. Dental trauma was not significantly associated with gender, age or QoL. Crown color change by trauma was associated with esthetic impairment. Also esthetic impairment had a negative impact on QoL (p<0.05) and was associated with oral limitations (p<0.05). Conclusions: Esthetic impairment had a negative impact on children's quality of life, while dental trauma was not associated to it.

Estética em dentes decíduos traumatizados: clareamento e restauração / Aesthetics in traumatized primary teeth: bleaching and restoration

O trauma dental decorrente de quedas, acidentes e atividades esportivas tem alta prevalência e pode impactar na qualidade de vida das crianças e suas famílias devido às alterações estéticas adversas. Este trabalho relata o caso clínico de paciente do sexo feminino, 3 anos de idade que procurou atendimento odontológico devido à fratura da coroa e descoloração do dente 51 após trauma. Clinicamente foi observada a presença de fístula e abcesso na região do dente. O dente foi submetido a tratamento endodôntico, seguido de clareamento interno/ externo com peróxido de hidrogênio a 35%. Após a finalização do clareamento, realizou-se a restauração da fratura permitindo o restabelecimento da estética e função. Um acompanhamento de 5 anos foi realizado até a erupção completa da coroa do dente 11. Neste período, não se observou alterações clínicas nem radiográficas do dente traumatizado, e o dente sucessor irrompeu sem nenhum comprometimento. Concluiu-se que o clareamento interno/ externo de dente decíduo seguido da restauração foi satisfatório para o restabelecimento da estética e função dentária da criança sem nenhuma alteração para o germe sucessor.

Dental trauma caused by falls, accidents and sports activities has high prevalence and may influence the quality of life of children and their family due to adverse cosmetic changes. This case report presents a three years old gril who refered to dental care due to crown fracture and discoloration of primary central incisor after trauma. Clinically, it was observed the presence of fistula and abscess in the tooth region. Endodontic treatment was done followed by internal/external bleaching with 35% hydrogen peroxide. The tooth was then restored providing aesthetics and function for the patient. There was a five years follow-up until full eruption of permanentÆs central incisorÆs crown. In this period, there were no clinical or radiographic changes on the traumatized tooth, and the successor tooth erupted without any impairment. It was concluded that the result of internal/external primary tooth bleaching followed by restoration, was satisfactory restoring aesthetics and function with no alteration to the successor tooth.

Ortodontia na recuperação da estética após perda precoce de dente decíduo por trauma dental: relato de caso / Esthetic improvement with orthodontics after premature loss due to trauma of primary teeth: case report

O presente caso clínico tem por objetivo relatar a perda precoce do dente 51 devido a trauma e o restabelecimento estético do paciente após a recuperação do espaço perdido. Criança do sexo masculino com 4 anos de idade procurou atendimento após trauma no incisivo central superior decíduo com posterior exodontia, realizada há 8 meses. A mãe relatou incomodo causado pela ausência do elemento dental em relação à estética. No exame clínico observou-se ausência de lesões de cárie e perda de espaço devido à migração dos dentes laterais ao espaço do dente extraído. Foi proposto um recuperador de espaço removível com molas digitais e, após 45 dias, foi recuperado o espaço desejado. Na segunda etapa foi confeccionado um aparelho mantenedor de espaço estético fixo. A cor do dente 51 foi aferida clinicamente e os dentes 55 e 65 foram bandados. O modelo foi encaminhado a um laboratório para confecção de uma barra palatina soldada as bandas e um dente de acrílico na região do dente 51 foi acrescentado. Após cimentação do aparelho os responsáveis foram instruídos em relação à higiene e do acompanhamento a cada 6 meses. Os retornos do paciente ocorreram até verificarem-se sinais de erupção do dente permanente sucessor sendo, então, o aparelho removido. O paciente retornou para uma nova avaliação clínica após a completa erupção dos dentes 11 e 21 onde se verificou ausência de qualquer sequela. Conclui-se que o paciente e os pais ficaram satisfeitos com o reestabelecimento estético alcançado no tratamento quanto à estética, sendo o aparelho eficaz até a erupção do dente permanente.

This clinical case aims to report early tooth loss of the primary right maxillary central incisor due to trauma and the aesthetic reestablishment of the patient after recovery of the lost space. Male, 4 years old, after dental trauma, had the primary right maxillary central incisor extracted. The mother reported discomfort caused by the absence of the dental element in relation to aesthetics. In the examination there was no caries but there was space loss due to migration of the lateral teeth to space the extracted tooth. A removable orthodontic appliance has been proposed and, after 45 days, was recovered the loss space. In second step was made a maintainer aesthetic retainer appliance. The color of the teeth was clinically assessed and the primary maxillary second molars were banded. The model was sent to a laboratory for making a palatal bar welded bands and an acrylic tooth in the region of the primary right maxillary central incisor. After appliance cementing those responsible were instructed regarding hygiene and monitoring every six months. The patient returns occurred until there is an eruption sign of permanent tooth successor and then the aesthetic appliance was removed. The patient returned to a new clinical evaluation after complete eruption permanent successor tooth where there was absence of any sequel. We conclude that the patient and parents were satisfied with the aesthetic reestablishment until the eruption of the successor permanent tooth.

Association between Trauma to Primary Incisors and Crown Alterations in Permanent Successors

The aim of this study was to determine the prevalence of sequelae in permanent teeth that had their predecessors traumatized and investigate associated factors. The study was carried out with clinical and radiographic data from 137 patient charts of the Traumatized Patient Care Program, Federal University of Santa Catarina (Brazil), totalizing 253 teeth. Data were gathered on gender, age at the time of trauma, type of trauma, type of post-trauma sequelae, trauma recurrence and crown alteration in the permanent successors. No statistically significant associations were found between permanent successor's crown alteration and gender, age at the time of trauma, post-trauma sequelae or trauma recurrence (p>0.05). Significant associations were found between severe trauma (crown fracture with pulp exposure, lateral luxation, intrusion and extrusion) in the primary incisors and permanent successor's crown alteration (p<0.05). Multivariate analysis revealed an association between severe trauma to the primary incisors and permanent successor's crown alteration (OR: 4.1 - IC: 1.7-10.1). Alterations in the crown of permanent successors are associated with severe trauma to the primary incisors, as primary teeth affected by severe trauma have a fourfold greater chance of exhibiting permanent successor crown alteration in comparison to primary teeth that had minor trauma.

O objetivo deste estudo foi determinar a prevalência de sequelas nos dentes permanentes, em crianças que tiveram o seu antecessor traumatizado e os fatores associados. O estudo foi realizado com dados clínicos e radiográficos de 173 prontuários de pacientes do Programa de Assistência ao Paciente Traumatizado, Universidade Federal de Santa Catarina (Brasil), totalizando 253 dentes. Os dados coletados foram: gênero, idade no momento do trauma, tipo de trauma, tipo de sequelas pós-trauma, recorrência de trauma e alteração na coroa dos sucessores permanentes. Não houve associação estatisticamente significativa entre alteração na coroa do sucessor permanente e gênero, idade no momento do trauma, sequela pós-trauma e recorrência de trauma (p>0,05). Foram encontradas associações significativas entre trauma grave (fratura coronária com exposição pulpar, luxação lateral, intrusão e extrusão) nos incisivos decíduos e o sucessor permanente com alteração na coroa (p<0,05). A análise multivariada revelou uma associação entre trauma grave nos incisivos decíduos e alteração no sucessor permanente (OR: 4.1- IC: 1,7-10,1). Alterações na coroa dos sucessores permanentes estão associadas com trauma grave nos incisivos decíduos. Dentes decíduos acometidos por trauma grave têm quatro vezes mais chance de apresentar alteração na coroa do permanente em comparação com trauma leve.
