Impact of treament with orthodontic aligners on the oral health-related quality of life.

BACKGROUND: There is an increasing interest in information on the effects of orthodontic aligners on the oral health-related quality of life (OHRQoL) of people. AIM: To compare the impact of orthodontic aligners versus conventional fixed appliances on OHRQoL, using a validated tool and controlling for sociodemographic and clinical variables. METHOD: Sixty-one individuals participated in this study. Group 1 (G1) consisted of 33 individuals under treatment with orthodontic aligners and Group 2 (G2) comprised 28 individuals under treatment with conventional fixed appliances. OHRQoL was evaluated with the Oral Health Impact Profile (OHIP-14) in which 14 items are distributed across seven dimensions: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. The higher the score, the more negative is the perception of the individual regarding his/her OHRQoL. Descriptive statistics, Mann-Whitney test, and Poisson regression were performed. Effect Size (ES) and Minimal Clinically Important Difference (MCID) were also determined. RESULTS: Participants' mean age was 30.69 years. Individuals in G1 had a significantly lower score for physical pain and the total score of OHIP-14 compared to individuals in G2 (p < 0.05). The ES was large (ES = 0.74) for physical pain and moderate (ES = 0.46) for the total score. The ES was moderate for physical disability (ES = 0.50). The difference between groups for physical pain (1.30) and for physical disability (0.90) was greater than the MCID (0.87 and 0.88, respectively). Poisson regression showed that G2 individuals showed a score for physical pain 1.39 times higher than those of G1 in the adjusted model (OR = 1.39, [1.03-1.89], p = 0.031). CONCLUSION: Those under treatment with orthodontic aligners have a more positive perception of OHRQoL compared to those wearing fixed appliances.

Probable sleep and awake bruxism in adolescents: A path analysis.

BACKGROUND: Bruxism has a multifactorial etiology, including the influence of sleep characteristics and chronotypes. AIM: To identify the pathways that influence the occurrence of probable sleep bruxism (PSB) and probable awake bruxism (PAB) in adolescents. DESIGN: A total of 403 adolescents, aged 12-19 years, participated in the study. Parents/caregivers filled out a questionnaire about sociodemographic issues and the adolescent's health conditions, and the adolescents about sleep characteristics, occurrence of bruxism (based on previous study and the International Consensus of Bruxism), and chronotype (Circadian Energy Scale). Clinical examinations were performed. Statistical analysis included descriptive analysis and path analysis. RESULTS: PSB and PAB are related to each other, with moderate and positive correlation (ß = .390). Poor sleep quality and higher household income had a direct effect on both PSB (ß = -.138; ß = .123, respectively) and PAB (ß = -.155; ß = .116, respectively). Chronotype had a direct effect on PSB, in such a way that adolescents with a morningness chronotype tend to have PSB (ß = -.102). Adolescents that drool on the pillow (ß = .184) and/or have agitated sleep (ß = .104) tend to have PSB. CONCLUSION: Poor sleep quality, household income, morningness chronotype profile, drooling on the pillow, and agitated sleep influence the paths taken by PSB. PAB was influenced by the quality of sleep and family income.

Dental Caries in Children with Attention Deficit/Hyperactivity Disorder: A Meta-Analysis.

OBJECTIVES: The aim of the study was to evaluate whether children with attention deficit/hyperactivity disorder (ADHD) are more affected by dental caries than children without ADHD by means of a systematic review and meta-analysis. DESIGN: Electronic searches were performed in 4 databases (PubMed, Embase, Scopus, and Web of Science) in July 2021. Grey literature search in OpenGrey, a search in Google Scholar, and searches in the reference list of included articles were also conducted. The eligibility criteria were observational studies in which children with ADHD were compared with children without ADHD with respect to the dental caries. Study selection, data extraction, and risk of bias assessment, applying the Joanna Briggs tool were performed by 2 reviewers independently. Meta-analysis and assessment of heterogeneity among studies were conducted with the meta-package of RStudio using the R programming language (R Core Team, Vienna, Austria). Results of meta-analysis were provided in mean difference (MD), odds ratio (OR), and confidence intervals (CIs). For assessment of heterogeneity, Baujat plot and influence analysis plot were obtained. RESULTS: Thirteen studies were included and 10 were incorporated into meta-analyses. The meta-analysis showed that children with ADHD had a higher decayed, missing, and filled teeth (DMFT) index than their peers without ADHD (I2 = 42%; MD = 0.75 [0.38-1.13]). For decayed, missing, and filled surfaces (I2 = 0; MD = 0.39 [-0.02 to 0.80]) and decayed surfaces (ds) (I2 = 0%; MD = 0.35 [-0.63 to 1.33]), no difference between groups was observed. In addition, children with ADHD had higher odds of having dental caries than their healthy peers (OR = 3.31 [1.25, 8.73]; I2 = 0%). After assessment of heterogeneity among studies, sensitivity analysis was conducted for DMFT. One study was removed and the significant difference between groups remained. Children with ADHD had a significantly higher DMFT index than their peers without ADHD (MD = 0.98 [CI = 0.75, 1.20]; I2 = 0%) Risk of bias ranged from low to high. CONCLUSION: The main shortcoming of the included studies is the high risk of bias regarding the strategies to deal with confounding factors. Within its limitations, this systematic review and meta-analysis demonstrated that children with ADHD were more likely to develop dental caries than their healthy counterparts. FUNDING: No funding.

Sense of coherence and dental fear/dental anxiety: A systematic review and meta-analysis.

AIM: The aim of this systematic review and meta-analysis was to evaluate the association between sense of coherence (SOC) and dental fear/dental anxiety. METHODS: Computerized searches were performed in six databases. Gray literature and manual searches were also conducted. Study selection, risk of bias assessment, and meta-analyses were performed. The results of meta-analyses were reported in odds ratio (OR), mean difference (MD), and confidence interval (CI). RESULTS: After removing duplicates, 131 references were retrieved and the full texts of 12 were evaluated. Nine references met the eligibility criteria and were included. The results of meta-analyses demonstrated that individuals with a weaker SOC had a score in the dental anxiety/dental fear scale 6.04 times higher than individuals with a stronger SOC (OR = 6.04, CI = 2.62-13.91). Individuals with no dental anxiety/dental fear had a mean score of the SOC scale higher than individuals with dental anxiety/dental fear (MD = 5.39, CI = 2.21-8.56). Sensitivity analysis demonstrated that the result of a higher mean score of the SOC scale among individuals with no dental anxiety/dental fear remained (MD = 7.38, CI = 3.79-10.98). Risk of bias ranged from low to high. The certainty of evidence was very low. CONCLUSION: Individuals with stronger SOC have lower levels of dental fear/dental anxiety.

Efetividade de mensagens eletrônicas nos telefones celulares na cooperação de pacientes ortodônticos no uso de elásticos, contenção e na presença às consultas: uma revisão sistemática e meta-análise / Effectiveness of electronic messages in mobile phones in the cooperation of orthodontic patients during the wearing of elastics and retainers, and in attendance to appointments: a systematic review and meta-analysis

Objetivo: Avaliar o efeito de mensagens por WhatsApp, mensagem de texto (SMS), ou aplicativos na cooperação dos pacientes ortodônticos para usar elásticos, contenção e para não faltar ou atrasar para as consultas. Métodos:Foram conduzidas buscas em cinco bases de dados eletrônicas, no OpenGrey e Google Scholar sem restrição de data/idioma de publicação. Seleção dos estudos, extração de dados e análise da qualidade metodológica dos artigos com a ferramenta Cochrane foram realizados. Resultados de meta-análises foram apresentados em razão das chances (RC) e intervalo de confiança (IC). Resultados: Oito estudos foram incluídos. Indivíduos que receberam mensagens por aplicativo apresentaram um número menor de comparecimentos falhos (p < 0,05). Indivíduos que receberam mensagens por WhatsApp obtiveram maior eficácia na correção da má oclusão classe II com elásticos e uma menor diminuição da distância intercaninos (p < 0,05) do que aqueles que não receberam mensagens. Para irregularidade dos incisivos, não houve diferença entre quem recebeu ou não recebeu mensagem de texto (p = 0,92). Entre indivíduos que recebiam mensagens por SMS, o número de comparecimentos à consulta foi maior que o número de não comparecimentos (RC = 15,48; IC = 1,04­230,24), além do maior uso de elásticos (p = 0,001). Não há diferença no comparecimento à consulta entre indivíduos que receberam uma mensagem prévia por SMS e quem recebeu ligação telefônica prévia (RC = 1,11; IC = 0,30 ­ 4,05), ou quem recebeu e-mail (p > 0,05). A qualidade metodológica variou de baixo a alto. Conclusão: Mensagens em celulares são eficientes na redução de faltas nas consultas, no número de comparecimentos falhos, no aumento do uso de elásticos e contenção.

Aim: To evaluate the effect of messages via WhatsApp, text message (SMS), or apps on the cooperation of orthodontic patients during the wearing of elastics and retainers as well as attendance and delay at appointments. Methods: Searches in five electronic databases, OpenGrey, and Google Scholar were performed without restrictions on publication date/language. Selection of the studies, data extraction, and methodological quality analysis of articles with the Cochrane tool were performed. Results of meta-analysis were provided in odds ratio (OR) and confidence intervals (CI). Results: Eight studies were included. Among those who received app messages, a lower number of appointment failures (delay) was observed (p < 0.05), and among those who received WhatsApp messages, a greater effectiveness of correction of class II malocclusion with elastics and a lower intercanine distance reduction (p < 0.05) were observed compared to those who did not receive messages. For incisor irregularity, there was no difference between individuals who received and those who did not receive a text message (p = 0.92). Among those receiving previous SMS messages, the number of appointment attendances was higher than the number of no-shows (OR = 15.48; CI = 1.04­230.24). Wearing of elastics was also higher (p = 0.001). No difference was found in appointment attendances between individuals who received previous SMS messages and individuals who received previous phone calls (OR = 1.11; CI = 0.30­4.05), or those who received e-mails (p > 0.05). The risk of bias varied from low to high. Conclusion: Messages in mobile phones are efficient in reducing consultation no-shows and failure in attendance, as well as in increasing the wearing of intermaxillary elastics and retainers.

Impacto do isolamento social pela pandemia da COVID-19 nas consultas odontopediátricas: uma revisão sistemática e meta-análise / Impact of social isolation caused by the COVID-19 pandemic on pediatric dentistry appointments: a systematic review and meta-analysis

Objetivo: Avaliar estudos que mostraram o impacto do isolamento social pela pandemia da COVID-19 nas consultas odontopediátricas. Métodos: Estudos originais que tenham mostrado o impacto do isolamento social nas consultas de crianças e adolescentes com um(a) odontopediatra foram incluídos. Buscas no Web ofScience, Scopus, Embase e PubMed foram realizadas. A seleção dos estudos foi feita por dois autores. O risco de viés foi avaliado com a escala Universidade de Adelaide. Resultados das meta-análises foram fornecidos em razão de chances (RC) e intervalo de confiança (IC). Resultados:Setecentas e noventa e quatro referências foram avaliadas e quatro estudos foram incluídos. A proporção de consultas realizadas em 2019 (antes da pandemia) para tratamento restaurador (RC = 22,65; IC = 20,57­24,93), extração de dentes (RC = 15,96; IC = 14,78­17,23) e tratamento endodôntico (RC = 9,21; IC = 7,72­10,98) foi significativamente maior que a proporção de consultas realizadas em 2020 (após o início da pandemia). A proporção de pais/responsáveis que não levariam seus(suas) filhos(as) à uma consulta com o odontopediatra foi significativamente maior entre indivíduos com mais medo durante a pandemia (escore 6 a 10) do que entre indivíduos com menos medo durante a pandemia (escore 0 a 5) (RC = 8,41; IC = 5,06­13,98). A proporção de pais/responsáveis que não levariam seus(suas) filhos(as) à uma consulta com o odontopediatra em regiões com mais de 100 casos de COVID-19 foi significativamente maior do que em regiões com até 100 casos (RC = 2,45; IC = 1,55­3,88). A avaliação do risco de viés variou de baixo a alto. Uma limitação dessa revisão foi o número restrito de estudos incluídos. Conclusão: O isolamento social pode ter contribuído para uma redução no número de consultas odontopediátricas devido à insegurança dos pais de levarem seus(suas) filhos(as) ao consultório odontológico. Esses resultados podem ser importantes para os clínicos e os organizadores de serviços de saúde.

Aim: To evaluate studies that showed the impact of social isolation caused by the COVID-19 pandemic on pediatric dentistry appointments. Methods: This work included original studies that have evaluated the impact of social isolation in children's and adolescents' appointments with a pediatric dentist. Searches were conducted in Web of Science, Scopus, Embase, and PubMed databases. Study selection was carried out by two authors. Risk of bias was assessed using the University of Adelaide scale. Results of meta-analyses were provided in odds ratio (OR) and confidence interval (CI). Results: Our study evaluated 794 references, of which four studies were included. The proportion of dental appointments performed in 2019 (before the pandemic) for restorative treatment (OR = 22.65; CI = 20.57­24.93), tooth extraction (OR = 15.96; CI = 14.78­17.23), and endodontic treatment (OR = 9.21; CI = 7.72­10.98) was significantly higher than the proportion of dental appointments performed in 2020 (after the onset of the pandemic). The proportion of parents/guardians who would not take their children to an appointment with a pediatric dentist was significantly higher among individuals who were more afrais during the pandemic (score 6 to 10) than among individuals who were less afraid during the pandemic (score 0 to 5) (OR = 8.41; CI = 5.06­13.98). The proportion of parents/guardians who would not take their children to an appointment with a pediatric dentist in regions with more than 100 cases of COVID-19 was significantly higher than in regions with up to 100 cases (OR = 2,45; CI = 1.55­3.88). Risk of bias assessment ranged from low to high. A limitation of this review was the restricted number of included studies. Conclusion: Social isolation caused a decline in the number of appointments with a pediatric dentist due to parents' insecurity about taking their children to the dental office. These results are important for both dental clinicians and healthcare decision-makers.

Cárie dentária em crianças e adolescentes com Diabetes tipo 1: uma revisão sistemática e meta-análise / Dental caries in children and adolescents with type 1 Diabetes: a systematic review and meta-analysis

Objetivo: O objetivo dessa revisão sistemática e meta-análise foi avaliar estudos que fizeram uma comparação da ocorrência de cárie dentária entre crianças/adolescentes com Diabetes tipo 1 (DM1) e crianças/adolescentes sem essa condição. Métodos:Buscas computadorizadas no Web ofScience, Scopus, Lilacs, PubMed, OpenGrey e Google Scholar foram realizadas até dezembro de 2020. A seleção dos estudos foi feita por dois autores independentemente. Referências que preenchiam os critérios de elegibilidade foram incluídas. O risco de viés foi avaliado com a escala Newcastle Ottawa. Meta-análises foram conduzidas. Diferença média (DM) e intervalos de confiança (IC) foram fornecidos. Resultados: Durante as buscas nas bases de dados, 751 referências foram recuperadas. Após remoção de 102 duplicatas, 649 referências foram avaliadas e 16 estudos foram incluídos nessa revisão sistemática e meta-análise. Os estudos incluídos tiveram resultados discrepantes. Duas meta-análises demonstraram que não houve diferença significativa na média de dentes permanentes com cárie entre crianças/adolescentes com DM1 e crianças/adolescentes sem DM1 (DM = 0,07; IC = -0,68 ­ 0,82) e que não houve diferença significativa na média de superfícies de dentes permanentes com cárie entre crianças/adolescentes com DM1 e crianças/adolescentes sem DM1 (DM = 0,20; IC = -2,22 ­ 2,61). Uma terceira meta-análise revelou que crianças/adolescentes sem DM1 apresentavam uma média de dentes decíduos com cárie significativamente maior do que crianças/adolescentes com DM1 (DM = 0,34; IC = 0,31 ­ 0,37). O maior problema de risco de viés dos estudos foi para a definição dos controles e comparação de casos e controles. Conclusão: A ocorrência de cárie parece ser menor entre crianças/adolescentes com DM1 em comparação a crianças/adolescentes sem DM1.

Aim:The aim of this systematic review and meta-analysis was to evaluate studies in which children/adolescents with type 1 Diabetes (DM1) were compared with children/adolescents without DM1 as regards dental caries. Methods: Electronic searches in Web ofScience, Scopus, Lilacs, PubMed, OpenGrey, and Google Scholar databases were conducted up to December/2020. Study selection was carried out separately by two reviewers. References that met the eligibility criteria were included. Risk of bias was evaluated using the Newcastle Ottawa scale. Meta-analyses were conducted. Mean difference (MD) and confidence intervals (CI) were provided. Results:In the database searches, 751 references were retrieved. Following the removal of 102 duplicates, 649 references were assessed, and 16 studies were included in this systematic review and meta-analysis. Discrepancies in results were found among the included studies. Two meta-analyses demonstrated no significant difference between children/adolescents with DM1 and children/adolescents without DM1 regarding the mean number of permanent teeth with caries (MD = 0.07; CI = -0.68 ­ 0.82), as well as no significant difference between children/adolescents with DM1 and children/adolescents without DM1 with respect to the mean number of permanent tooth surfaces with caries (MD = 0.20; CI = -2.22 ­ 2.61). The third meta-analysis revealed that children/adolescents without DM1 had a significantly higher mean number of primary teeth with caries in comparison to children/adolescents with DM1 (MD = 0.34; CI = 0.31 ­ 0.37). The major issues in the risk of bias assessment were the definition of controls and comparison between cases and controls. Conclusion: The occurrence of caries seems to be lower in children/adolescents with DM1 than in children/adolescents without DM1.

Association of facial type with possible bruxism and its related clinical features in adolescents: A cross-sectional study.

OBJECTIVES: The assessment of bruxism and its clinical characteristics is acknowledged in literature. This study aimed to evaluate the association of adolescents' facial patterns with bruxism and its related clinical features in the form of signs and symptoms. MATERIALS AND METHODS: Four hundred and three adolescents answered a questionnaire evaluating sleep bruxism (SB) and awake bruxism (AB). Parents/caregivers answered a questionnaire evaluating the adolescents' sleep features (drooling on the pillow, snoring). Adolescents' facial (dolichofacial/brachyfacial/mesofacial) and clinical features (pain in masseter/temporal muscle, indentations marks on the tongue, linea alba, tooth attrition, mouth's maximum opening and masseter electrical activity) were evaluated. Multinomial regression was performed. Odds ratio (OR) and confidence intervals (CI) were provided. RESULTS: Brachyfacial adolescents were less likely to present possible AB compared to mesofacials (OR=0.46, CI=0.21-0.98). Brachyfacial adolescents were more likely to present pain in the temporal muscle (OR=6.59, CI=2.18-19.87) and a higher number of posterior teeth with attrition (OR=1.25, CI=1.02-1.57) compared to mesofacials. Dolichofacial adolescents were more likely of not presenting pain in the masseter muscle (OR=2.23, CI=1.03-4.83), had a higher mouth's maximum opening (OR=1.43, CI=1.04-1.97), had a higher number of posterior teeth with attrition (OR=1.17, CI=1.00-1.37) and were more likely to drool on the pillow (OR=2.05, CI=1.15-3.67) compared to mesofacials. Dolichofacial adolescents were more likely of not presenting pain in the temporal muscle (OR=6.36, CI=2.30-17.54), to present themselves without marks on the tongue (OR=2.26, CI=1.09-4.69) and present a higher mouth's maximum opening (OR=2.09, CI=1.40-3.13) compared to brachyfacials. CONCLUSION: Bruxism and its clinical features differ among dolichofacial, brachyfacial and mesofacial adolescents.

Severe malocclusion negatively impacts adolescents' quality of life

Aim: To assess the impact of severe malocclusion on adolescents' oral health- related quality of life (OHRQoL). Methods: This study consisted of a sample of 117 adolescents between 11 and 12 years, who answered the Brazilian version of the short form of the Child Perception Questionnaire (CPQ 11-14 ). This questionnaire has 16 items distributed equally across four domains: oral symptoms (OS), functional limitations (FL), emotional well-being (EW) and social well-being (SW). Higher scores indicate a greater negative impact on OHRQoL. Malocclusion was evaluated using the Dental Aesthetic Index. Adolescents were assigned to the following categories: no or slight malocclusion, defined malocclusion and severe malocclusion. Descriptive analysis, the Kruskal Wallis test, post hoc test, univariate and multivariate logistic regression were conducted. Results: Individuals with severe malocclusion presented significantly higher scores than those with no or slight malocclusion for the EW ( p =0.001), SW ( p =0.027) and for the overall CPQ 11-14 score ( p =0.015). Adolescents with severe malocclusion showed a 2.63 greater chance of presenting a high negative impact on OHRQoL than those with no or slight malocclusion regardless of the confounding variables (CI=1.07­6.45, p =0.035). Conclusion: Severe malocclusion negatively impacts adolescents' OHRQoL.

Objetivo: Avaliar o impacto da má oclusão severa na qualidade de vida relacionada à saúde bucal de adolescentes (OHRQoL). Métodos: Este estudo consistiu em uma amostra de 117 adolescentes entre 11 e 12 anos, que responderam à versão brasileira da forma abreviada do Child Perception Questionnaire (CPQ11- 14). Este questionário tem 16 itens distribuídos igualmente em quatro domínios: sintomas bucais (SO), limitações funcionais (LF), bem-estar emocional (BE) e bem- estar social (BS). Escores mais altos indicam um impacto negativo maior na OHRQoL. A má oclusão foi avaliada por meio do Índice Estético Dental. Os adolescentes foram alocados nas seguintes categorias: sem má oclusão/má oclusão leve, má oclusão definitiva e má oclusão severa. Análise descritiva, teste de Kruskal Wallis, teste de Dunn, regressão logística univariada e multivariada foram conduzidas. Resultados: Indivíduos com má oclusão severa apresentaram escores significativamente mais elevados do que aqueles sem má oclusão/má oclusão leve para o BE ( p =0,001), BS ( p =0,027) e para o escore total do CPQ11-14 ( p =0,015). Adolescentes com má oclusão severa apresentaram 2,63 vezes mais chance de apresentar um impacto negativo alto na OHRQoL do que aqueles sem má oclusão/má oclusão leve, independentemente das variáveis de confusão (IC=1,07-6,45, p =0,035). Conclusão: A má oclusão severa afeta negativamente a OHRQoL dos adolescentes.

Associação entre tipo facial, possível bruxismo do sono e em vigília e características clínicas em adolescentes / Association among facial type, possible sleep bruxism and awake bruxism and clinical characteristics in adolescents

As características dos músculos faciais, a variação do formato e a configuração facial, tanto no sentido vertical como no sentido horizontal, determinam a classificação de tipo facial. Observar o tipo facial é importante, pois indivíduos com diferentes tipos faciais apresentam características próprias. O objetivo deste estudo foi avaliar a ocorrência do bruxismo do sono e em vigília e suas características clínicas entre adolescentes dolicofaciais, braquifaciais e mesofaciais. Quatrocentos e três indivíduos participaram. O tipo facial dos adolescentes (dolicofacial, braquifacial ou mesofacial) foi determinado através do Índice facial. O possível bruxismo do sono e em vigília foram avaliados por meio de um questionário de auto relato. As características clínicas dor nos músculos temporal e masseter, ronco, hábito de babar no travesseiro, marcas na língua, linha alba, desgaste em dentes anteriores, desgaste em dentes posteriores, máxima abertura de boca e atividade elétrica do músculo masseter também foram avaliadas. Foi realizada estatística descritiva e regressão multinomial. Os resultados foram expressos em odds ratio (OR) e intervalos de confiança (IC). Entre os 403 adolescentes, 234 (58,1%) eram do sexo feminino e 169 (41,9%) do sexo masculino. Em relação ao tipo facial, a maioria dos adolescentes apresentou o tipo dolicofacial (54,3%), seguido pelos adolescentes mesofaciais (26,1%) e aqueles que apresentaram o tipo braquifacial (19,6%). A média de idade dos adolescentes foi de 14,36 anos (±1,56). Adolescentes braquifaciais tinham menos chances de apresentarem possível bruxismo em vigília (algumas vezes) em comparação aos adolescentes mesofaciais (OR=0,45, IC=0,210,98). Adolescentes braquifaciais tinham mais chances de apresentarem dor no músculo temporal (OR=6,58, IC=2,17-19,93) e um número maior de dentes posteriores com desgaste (OR=1,24, IC=1,02-1,52) em comparação aos adolescentes mesofaciais. Adolescentes dolicofaciais tinham mais chances de não apresentarem dor no músculo masseter (OR=2,21, IC=1,02-4,79), de apresentarem um maior ângulo de abertura de boca (OR=1,58, IC=1,13-2,20), um número maior de dentes posteriores com desgaste (OR=1,17, IC=1,00-1,38) e babar no travesseiro algumas vezes (OR=2,06, IC=1,15-3,68) em comparação aos adolescentes mesofaciais. Adolescentes dolicofaciais tinham mais chances de não apresentarem dor no músculo temporal (OR=5,73, IC=2,12-15,49), de não apresentarem marcas de edentação na língua (OR=2,23, IC=1,08-4,57) e de apresentarem um maior ângulo de abertura de boca (OR=2,18, IC=1,46-3,24) quando comparados a adolescentes braquifaciais. O bruxismo e suas características clínicas diferiram entre adolescentes dolicofaciais, braquifaciais e mesofaciais.

The characteristics of the facial muscle, the variation of the shape of the face, both vertically and horizontally, determine the facial type of an individual. Diagnosis of the facial type and its associated features is important, since individuals with different facial types have their own characteristics. The objective of this study was to compare the occurrence of sleep and awake bruxism and their associated clinical characteristics among dolichofacial, brachyfacial and mesofacial adolescents. Four hundred three individuals participated. Adolescents? facial type (dolichofacial, brachyfacial or mesofacial) was determined. Possible sleep and awake bruxism were assessed. The clinical characteristics pain in the masseter and in the temporal muscle, snoring, drooling on the pillow, indentations marks on the tongue, linea alba on the inner cheek, attrition in anterior teeth, attrition in posterior teeth, maximum opening of the mouth and electrical muscle activity were also evaluated. Descriptive statistics and multinomial regression were performed. Results were provided in odds ratio (OR) e confidence intervals (CI). Among the 403 adolescents, 234 (58.1%) were female individuals and 169 (41.9%) were male individuals. As regards the facial type, most adolescents presented a dolichofacial facial type (54.3%), followed by adolescents with mesofacial facial type (26.1%) and those presenting a brachyfacial facial type (19.6%). Adolescents? mean age was 14.36 years. Brachyfacial adolescents were less likely to present possible awake bruxism compared to mesofacial adolescents (OR=0.45, CI=0.21-0.98). Brachyfacial adolescents were more likely to present pain in the temporal muscle (OR=6.58, CI=2.17-19.93) and a higher number of posterior teeth with attrition (OR=1.24, CI=1.02-1.52) compared to mesofacial adolescents. Dolichofacial adolescents were more likely of not presenting pain in the masseter muscle (OR=2.21, CI=1.02-4.79), had a greater maximum opening of the mouth (OR=1.58, CI=1.13-2.20), had a higher number of posterior teeth with attrition (OR=1.17, CI=1.00-1.38) and were more likely to drool on the pillow sometimes (OR=2.06, CI=1.15-3.68) compared to mesofacial adolescents. Dolichofacials adolescents were more likely of not presenting pain in the temporal muscle (OR=5.73, CI=2.12-15.49), to present themselves without marks on the tongue (OR=2.23, CI=1.08-4.57) and with a greater maximum opening of the mouth (OR=2.18, CI=1.46-3.24) compared to brachyfacial adolescents. Bruxism and its clinical characteristics differ among dolichofacial, brachyfacial and mesofacial adolescents.
