Is There an Increase in Possible Sleep Bruxism in Children Over Time? A Longitudinal Study.

BACKGROUND: Bruxism is a behaviour that has several consequences in an individual's life, especially when it starts in childhood. However, bruxism can be a potential protective factor, which is an attribute that reduces the chance of a negative health outcome. OBJECTIVES: To evaluate the incidence of sleep bruxism (SB) and dental wear in children and adolescents. MATERIALS AND METHODS: This longitudinal study began in 2014 and 2016 (baseline) with initial 1816 children followed for 5 and 3 years, respectively. The follow-up data collection started in 2019. The diagnosis of SB was parents report (baseline) and self-report (follow-up) due to age groups of each phase, and questions related to symptoms of SB were collected. Five calibrated examiners (kappa >0.7) collected the clinical data. The clinical variables were dental erosion and dental wear. Contextual, individual, behaviour and clinical characteristics were collected. A multilevel logistic regression model was used to investigate the association of contextual, individual, behaviour and clinical characteristics with SB. Poisson regression for repeated measures was performed to evaluate the incidence of SB and dental wear (incidence rate ratio-IRR and confidence interval-95% CI). RESULTS: Two hundred and fifty-three children and adolescents answered questionnaires and were clinically examined. The mean age of the follow-up in 2019 was 11.25 years old (±2.19). There was no increase in the incidence of SB (95% CI: 0.74-1.35). Children/adolescents had a 2.2 higher risk to present dental wear (95% CI: 1.89-2.60). SB at the follow-up was associated with the contextual variable, earache, erosion and awake bruxism. CONCLUSIONS: In this population, children with SB remained with this behaviour and showed higher dental wear over the years.

Factors associated with the anxiety score of deaf and hearing mothers. / Fatores associados ao escore de ansiedade de mães surdas e ouvintes.

PURPOSE: To associate maternal anxiety with sociodemographic factors, breastfeeding practices, oral habits, and the child's entry into daycare among deaf and hearing (non-deaf) mothers. METHODS: This retrospective comparative cross-sectional study included 116 mothers (29 deaf and 87 hearing) of children aged between two and five years. Deaf mothers belonged to a reference center in the city, while hearing mothers were contacted in public daycares where their children were enrolled. Mothers underwent interviews covering socio-economic factors and child development-related aspects. Additionally, they completed the Brazilian Beck Anxiety Inventory, adapted for both deaf and hearing individuals, serving as instruments to assess anxiety. The Kolmogorov-Smirnov normality test, Kruskal Wallis test, Mann-Whitney test, and Poisson Regression were employed for statistical analyses (p<0.05). RESULTS: Deaf mothers exhibited anxiety scores one and a half times higher than hearing mothers. Moreover, mothers of children with thumb-sucking habits showed higher anxiety scores, while mothers whose children started attending daycare as infants demonstrated lower anxiety scores compared to mothers of children without such habits and who did not attend daycare. CONCLUSION: Deaf mothers displayed higher anxiety levels when compared to hearing mothers. Children's behaviors, such as thumb-sucking habits, and early enrollment in daycare during the first year of life influenced maternal anxiety.

OBJETIVO: Associar a ansiedade materna aos fatores sociodemográficos, pratica de aleitamento, hábitos bucais e ingresso da criança em creche entre mulheres surdas e ouvintes. MÉTODO: Participaram deste estudo transversal retrospectivo comparativo, 116 mães (29 surdas e 87 ouvintes) de crianças na faixa etária entre dois e cinco anos. As mães surdas pertenciam a um centro de referência da cidade e as mães ouvintes foram contatadas em creches públicas, onde seus filhos estavam matriculados. As mães foram submetidas a entrevista sobre fatores socioeconômicos e relacionados ao desenvolvimento dos filhos, além de realizarem o preenchimento do Inventário Brasileiro de Ansiedade de Beck, nas versões para surdos e ouvintes, que foram instrumentos usados para avaliar a ansiedade. O teste de normalidade de Kolmogorov-Smirnov, os testes de Kruskal Wallis, Mann-Whitney e Regressão de Poisson foram utilizados para análises estatísticas (p <0,05). RESULTADOS: Mães surdas apresentaram escore de ansiedade uma vez e meia maior que mães ouvintes. Além disso, mães de crianças com hábito de sucção de dedo apresentaram maior escore de ansiedade e mães cujos filhos começaram a frequentar a creche ainda bebês apresentaram menor escore de ansiedade, quando comparados a crianças sem o hábito e que não frequentavam a creche. CONCLUSÃO: Mães surdas apresentaram maior ansiedade quando comparadas às ouvintes. Comportamento dos filhos com hábitos de sucção de dedo e o ingresso em creches no primeiro ano de vida influenciaram a ansiedade materna.

Parental Reports of Children's Dental Pain Experience and Associated Factors among Brazilian Children.

Exploring children's dental pain experiences helps to develop healthcare policies for improving oral health and quality of life. A cross-sectional study involved 300 parents/caregivers of four- to seven-year-old children using snowball sampling. Parents/caregivers self-completed an online questionnaire on sociodemographic characteristics, parenting styles, their child's oral hygiene practices, free sugar consumption, and dental history. The questionnaire was created using Google Forms and was disseminated to parents/caregivers via E-mail and/or WhatsApp©. Descriptive and Poisson regression analyses were performed (p < 0.05). Children's dental pain experience was reported by 20.3% of the parents. The authoritative parenting style was predominant. The child's mean age at the first consumption of sugar was 1.38 (±0.64) years, and 40.3% of the children had high-free sugar consumption. The mean age for the first dental appointment was 2.26 (±1.31) years, and 24.3% of the children never went to a dental appointment. The prevalence of dental pain experience was higher in children who attended their first dental appointment later (PR: 1.02; CI 95%: 1.01-1.03) and among those with high-free sugar consumption (PR: 1.90; CI 95%: 1.21-3.00). High sugar consumption and delay in the first dental appointment may increase the likelihood that children will experience dental pain.

A global bibliometric analysis on the relationship between tinnitus and temporomandibular disorders.

BACKGROUND AND OBJECTIVES: This global bibliometric review aimed to investigate trends in publications relating to tinnitus and TMD. METHODS: A search was performed in eight databases (June/2022), by independent researchers with relevant keywords about tinnitus and TMD, without restriction of date or language. Original research or case report/series evaluating prevalence, association and risk related to tinnitus and TMD were included. Independent examiners selected studies by title and abstract and performed data extraction. Data about publication and researchers, study population, objective, study design and diagnostic criteria for tinnitus and TMD were exported to VintagePoint® for bibliometric analyses. Data about the direct association between tinnitus and TMD were extracted. RESULTS: One hundred and seventeen articles from 25 countries were included, most observational (68.4%) and evaluating association (N = 60; 44.8%). Among the 60 studies of association, 22 (36.6%) presented results of a direct association between the presence/absence of tinnitus and the presence/absence of TMD. Brazil (19.5%) and the United States (12.7%) were the countries with the most publications, and Dentistry (48.6%) was the main publication area. A growth in publications in Dentistry was observed in the past 30 years and in the past 10 years in Medicine. Half of the studies included the elderly population (50.2%). The main diagnostic criterion for both tinnitus (37.8%) and TMD (28%) was general questionnaires and/or self-report. CONCLUSION: There is a growing trend in publications relating to tinnitus and TMD, especially in Dentistry, with a predominance of observational and association studies in the elderly population using questionnaires and/or self-report. More research with robust diagnostic methods and other study designs should be encouraged in the future.

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.

Effects of rapid maxillary expansion on sleep disturbance scale for children: A longitudinal CASE-series study.

OBJECTIVE: To evaluate the effects of rapid maxillary expansion (RME) on Sleep Disturbance Scale for Children (SDSC) with maxillary atresia. MATERIALS AND METHODS: The sample consisted of 27 paediatric patients evaluated through a Brazilian version of the SDSC, answered by their guardians at the following experimental time points: T0 (before installing the Hyrax expander), T1 (on the day of expander stabilization), T2 (3 months after expander stabilization), T3 (immediately after expander removal, following 6 months of retention), and T4 (3 months post-retention). Multilevel Poisson analysis adjusted for repeated measures was performed to compare outcomes across the assessment time points. RESULTS: The mean age of patients was 9.1 years (SD = 1.46). The total SDSC scores decreased and were statistically significant from T2 onwards (P < .01), with a decrease of 24% at T4 compared with T1 (IRR 0.76; 95% CI 0.69-0.84). The mean scores at T4 were already lower than the cutoff point for risk of sleep disorders. Regarding the specific domains, there was a significant reduction in sleep breathing disorders, sleep-wake transition disorders, and disorders of excessive somnolence as of T2 (P < .01), T3 (P < .05) and T4 (P < .05), respectively. CONCLUSION: RME in children with maxillary atresia had a positive effect on the reduction of total SDSC scores after 3 months of expander stabilization, sustained over 6 and 9 months and significant reduction in sleep breathing disorders domain, sleep-wake transition disorders domain, and disorders of excessive somnolence domain over time points.

Diagnosis and prevalence of probable awake and sleep bruxism in adolescents: an exploratory analysis.

The aims of this study were to perform an exploratory analysis of probable awake (AB) and sleep bruxism (SB) prevalence using of different diagnosis criteria based on the International Consensus; evaluate the associations between self-report and clinical signs/symptoms in adolescents. Participated in this cross-sectional study 403 adolescents aged 12- to 19-years-old enrolled in public and private schools from Belo Horizonte, Brazil. Parents/caregivers answered a questionnaire about sociodemographic status and adolescents' health status. Adolescents answered a questionnaire evaluating AB (e.g., grinding and clenching) and SB (e.g., grinding, bracing, and thrusting) activities and frequent headaches. A clinical examination was performed on adolescents to evaluate bruxism clinical signs/symptoms (pain upon palpation on masseter and temporal, linea alba, indentation on the tongue and attrition wear severity). Descriptive statistics and Pearson's Qui-square test were performed (P≤0.05). Adolescents mean age was 14.3±1.5 years, and 58.1% were female. Self-report of SB was identified in 31% of participants and self-report of AB in 51.6%. Almost all adolescents (99%) presented at least one tooth with attrition wear (98.5% on enamel and 0.5% on dentin), with a mean number of 12.4±5.7 teeth. Depending on the diagnosis criteria, the prevalence of probable SB and AB varied from 0- 99% and 0.2- 99%, respectively. A high inconsistency was found for the prevalence of probable AB and SB in adolescents, which were influenced by the different clinical sings/symptoms used as diagnosis criteria. Frequent headaches and pain upon palpation on masseter and temporal muscle were associated to self-report of AB and SB among adolescents.

Association Between Attention-Deficit/Hyperactivity Disorder Symptoms and Sleep, Bruxism and Dental Trauma in Pediatric Population: A Preliminary Study.

Purpose: To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) symptoms reported by parents and the variables sleep problems, possible sleep bruxism, possible awake bruxism and dental trauma (DT), and its mode of occurrence in children and adolescents.
Methods: A cross-sectional study was conducted with the parents of 144 four- to 16-year-old subjects through a questionnaire on demographics, subjects' sleep, self-reported bruxism and DT mode of occurrence. The Swanson, Nolan and Pelham scale IV was used to assess ADHD signs and subtypes. Bivariate and multivariate analysis were performed (P <0.05).
Results: The subjects' mean age was 7.9 years (±2.8 years) and 50.7 percent were boys. DT was reported in 80 percent of those with the hyperactive/impulsive subtype (ADHD-HI) and 72.7 percent of those with the combined subtype (ADHD-C). DT was caused solely by falls in the ADHD-C and inattention subtypes (ADHD-I). ADHD-C was associated with somniloquy (prevalence ratio [PR]=1.075; P =0.010). ADHD-HI was associated with bad sleep quality (PR=1.194; P =0.005), possible sleep bruxism (PR=1.088, 95% confidence interval=1.006 to 1.176; P =0.034), possible awake bruxism (PR=1.146; P =0.024) and sleep duration (PR=0.88; P =0.02).
Conclusion: ADHD-C and -HI subtypes were associated with sleep characteristics. Possible sleep and awake bruxism were associated with symptoms of ADHD-HI. Despite no significant association, DT was present in most ADHD subjects, mostly due to falls.

Influence of the practice of sports, sleep disorders, and habits on probable sleep bruxism in children with mixed dentition.

OBJECTIVE: Investigate the association between sleep disorders and probable sleep bruxism (SB) in children eight to ten years of age. METHODS: A cross-sectional study was conducted with 739 schoolchildren in Brazil. Parents/guardians answered a sociodemographic questionnaire, the sleep disturbance scale for children, and the Circadian Energy Scale. Parafunctional habits were evaluated using the Nordic Orofacial Test-Screening. Multivariate logistic regression was performed (α = 5%), and a directed acyclic graph was used in the statistical model. RESULTS: The prevalence of probable SB was 9.1% and 58.6% of the children had sleep disorders. In the final model, having unmarried parents/guardians (OR = 1.98; 95% CI: 1.07-3.65), exhibiting parafunctional habits (OR = 2.02; CI: 1.01-4.06), not practicing sports (OR = 1.92; CI: 1.04-3.54), sleep-wake transition disorders (SWTD) (OR = 2.01; 95%CI: 1.12-3.62), and excessive daytime sleepiness (EDS) (OR = 2.17; 95%CI: 1.11-4.29) were significant associated with probable SB. CONCLUSION: The occurrence of probable sleep bruxism was influenced by the marital status of the parents/guardians, parafunctional habits, the non-practice of sports, and sleep disturbance (SWTD and EDS). This research contributes to the planning of public policies that include educational regimens at school to prevent sleep disorders and favor the reduction in sleep bruxism prevalence.

Evaluation of the association between self-reported sleep bruxism and chronotype and sleep quality among dental students / Avaliação da associação entre cronotipo, qualidade do sono e autorrelato de bruxismo do sono entre estudantes universitários de Odontologia

ABSTRACT Background Sleep bruxism (BS) is defined as involuntary jaw movements characterized by grinding and clenching teeth. Objective To verify the association between chronotype, sleep quality, and self-reporting of BS in dental students. Method A cross-sectional study was conducted with 214 undergraduate dental students at a public university in northeast Brazil. The participants answered the Munich Chronotype Questionnaire for the identification of chronotype and another questionnaire regarding daily aspects to collect information about sleep quality, self-reported sleep bruxism, the use of sleeping pills, snoring, concentration during daily activities and energy upon waking. Results The prevalence of self-reported sleep bruxism was 11.0%. In the final model, the eveningness chronotype (OR = 23.00; 95% CI: 2.36-223.84, p = 0.007), habitual snoring (OR = 3.12; 95% CI: 1.31-7.39, p = 0.01) and low energy upon waking in the morning (OR = 2.37; 95% CI: 1.96-5.58, p = 0.040) were associated with self-reported sleep bruxism. Conclusion The evening chronotype, presence of snoring, and low energy when waking up in the morning influenced self-reporting of sleep bruxism among undergraduate dental students.

Conclusão O cronotipo noturno, a presença do ronco e a baixa energia ao se levantar pela manhã influenciaram o autorrelato de bruxismo do sono entre os estudantes de graduação em Odontologia.

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

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

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

Precipitating factors of school bullying in victims and bully-victims from eight-to-eleven-years of age / Fatores precipitantes do bullying escolar em vítimas e vítimas-intimidadoras de oito a onze anos de idade

Aim: The aim of the present study was to identify precipitating factors of bullying in schoolchildren.Methods: A total of 425 schoolchildren aged eight to eleven years, enrolled in public and private schools in Lavras, Brazil, participated in this cross-sectional study. The schoolchildren answered two questions addressing characteristics that could affect their relationships with peers and completed the Brazilian version of the Olweus Bully/Victim Questionnaire. The characteristics investigated included weight, height, facial features, dentofacial appearance, and other individual factors, such as halitosis and wearing glasses. Parents answered a questionnaire on demographic characteristics. Descriptive analysis and multinomial logistic regression were performed (p ≤ 0.05).Results: Bully-victims were more likely to be enrolled in public schools (OR = 5.43, 95% CI: 1.14-25.91, p = 0.03). Victims of bullying were more likely to report characteristics such as halitosis, wearing glasses, and other aspects (OR = 3.31, 95% CI: 1.14-9.57, p = 0.02), as well as dentofacial appearance (OR = 3.80, 95% CI: 1.38-10.41, p = 0.01), as factors that affected interactions with peers.Conclusions: The findings show that physical appearance, socioeconomic aspect, and individual characteristics are factors associated with victims and bully-victims. Pediatric dentists should discuss these issues with their patients and parents/caregivers when taking patient history.

Objetivo:O objetivo do presente estudo foi identificar os fatores precipitantes do bullying em escolares.Métodos: Um total de 425 escolares de oito a onze anos matriculados em escolas públicas e privadas de Lavras, Minas Gerais, Brasil, participaram deste estudo transversal. Os escolares responderam duas perguntas abordando características que poderiam afetar seu relacionamento com seus pares e preencheram a versão brasileira do Olweus Bully/Victim Questionnaire. As características investigadas foram peso, altura, características faciais, aparência dentofacial e outros fatores individuais, como halitose e uso de óculos. Os pais responderam um questionário sobre características sociodemográficas. Análise descritiva e regressão logística multinomial foram realizadas (p ≤ 0,05). Resultados: As vítimas-intimidadoras eram mais propensas a serem de escolas públicas (OR = 5,43, IC 95%:1,14-25,91, p = 0,03). As vítimas de bullying foram mais propensas a relatar características como halitose, uso de óculos e outros aspectos (OR = 3,31, IC 95%: 1,14-9,57, p = 0,02), bem como aparência dentofacial (OR = 3,80, IC 95%: 1,38-10,41, p = 0,01) como fatores que afetaram suas interações com seus pares. Conclusões:Os achados mostram que a aparência física, o aspecto socioeconômico e as características individuais são fatores associados às vítimas e às vítimas-intimidadoras. Odontopediatras devem discutir essas questões com as crianças/adolescentes e seus pais/responsáveis ao obter a história do paciente.

Objetivo: Avaliar a qualidade e a confiabilidade do conteúdo de vídeos sobre Odontologia do Sono no YouTube™. Métodos: Foi realizada uma busca no YouTube™, utilizando o termo "Odontologia do Sono", na qual selecionou-se os 100 primeiros vídeos para análise realizada por dois pesquisadores. Foram incluídos vídeos sobre o tema, na língua portuguesa brasileira, com no máximo 24 minutos. Foram extraídos: título, data, duração, visualização, curtida, fonte, público-alvo, objetivo e assunto. A qualidade foi avaliada através da Escala de Qualidade Global (EQG), e a confiabilidade, através da adaptação de um índice previamente publicado, ambos pontuando até 5 pontos, onde mais pontos significavam maior qualidade e confiabilidade. Foram realizados os testes de Mann-Whitney U, Kruskal-Wallis e a correlação de Spearman (p < 0,05). Resultados: 58 vídeos foram incluídos, cuja mediana da duração foi 2,4 ± 7,6 minutos. A maioria dos vídeos era produzida por cirurgiões-dentistas (CD) (75,9%; n = 44), sobre apneia (96,6%; n = 56), com o objetivo educacional/informativo (65,5%; n = 38) e direcionado para leigos (58,6%; n = 34). A maioria apresentou mediana baixa de 2,0 ± 1,0 na EQG (41,4%; n = 24), e na escala de confiabilidade, a mediana de 3,0 ± 1,0 (60,3%; n = 35). Houve correlação moderada da EQG (p = 0,62; p < 0,01) e da confiabilidade (ρ = 0,41; p < 0,01) com a duração do vídeo, e também entre EQG e confiabilidade (ρ = 0,66; p < 0,01). Vídeos educacionais/informativos, produzidos por CD, e direcionados a leigos, apresentaram uma maior EQG e confiabilidade (p < 0,01). Vídeos que incluíam bruxismo tinham maior EQG (p = 0,01). Programas de televisão e vídeos que não eram comerciais apresentaram maior confiabilidade (p < 0,05). Conclusão:A maioria dos vídeos possuía qualidade baixa e confiabilidade moderada. Vídeos educacionais/informativos, feitos por CD, direcionados a leigos, que incluíam bruxismo, programas de televisão e que não eram comerciais, apresentaram maior qualidade e confiabilidade.

Aim: To assess the quality and reliability of video content on Dental Sleep Medicine on YouTube™. Methods: A search was performed on YouTube™ using the term "Dental Sleep Medicine". The first 100 videos were selected for analysis by two researchers. Videos on the subject were included, in Brazilian Portuguese with a maximum of 24 minutes. The following data were extracted: title, date, duration, views, likes, source, target audience, objective and subject. Quality was assessed using the Global Quality Scale (GQS), and reliability using a previously published index adapted, both ranging from 1 to 5 points, where more points meant greater quality and reliability. Spearman correlation, Mann-Whitney U, and Kruskal-Wallis test (p < 0.05) were performed. Results: 58 videos were included, with a median duration of 2.4 ± 7.6 minutes. Most of the videos were produced by dentists (75.9%; n = 44), about apnea (96.6%; n = 56), with an educational/informational objective (65.5%; n =38), and aimed at laypeople (58.6%; n = 34). Most had a low median of 2.0 ± 1.0 on the GQS (41.4%; n = 24), and on the reliability scale, the median was 3.0 ± 1.0 (60.3%; n = 35). There was a moderate correlation between both GQS (ρ = 0.62; p < 0.01) and reliability (ρ = 0.41; p < 0.01) with video duration, and also between GQS and reliability (ρ = 0 .66; p < 0.01). Educational/informational videos, produced by dentists, and aimed at laypeople showed higher GQS and reliability (p < 0.01). Videos that included bruxism had higher GQS (p = 0.01). Television programs and non-commercial videos were more reliable (p < 0.05). Conclusion: Most videos had low quality and moderate reliability. Educational/informational videos, made by dentists, aimed at laypeople, that included bruxism, television programs, and that were not commercials, presented higher quality and reliability.

Association between Level of Parental Oral Health Literacy and the Rational Use of Fluoride for Children from 0 to 4 Years of Age after Instruction: An Intervention Trial.

An inadequate level of oral health literacy (OHL) can hinder the understanding of dental information, which can have a negative impact on health promotion actions, such as the rational use of fluoride. The aims of the present study were (1) to look for association between parents/guardians' OHL and the amount of fluoride toothpaste used for children from zero to four years of age; (2) to compare the effect of different modes of educational interventions on the amount of fluoride toothpaste used for children from zero to four years of age; and (3) to assess the ability of parents/guardians to choose a toothpaste with adequate fluoride concentration, after the educational intervention. A randomized intervention study was conducted with parents/guardians of children from zero to four years of age (n = 145). The participants answered the Oral Health Literacy Adults Questionnaire and a questionnaire addressing sociodemographic characteristics. The participants were allocated to four intervention groups based on type of counseling (written, oral, written + photograph, and oral + photograph), with randomization stratified by level of OHL. The participants were instructed to place the adequate amount of toothpaste on a toothbrush for children from zero to four years of age (smear of 0.125 mg) before and after the intervention. The correct choice of toothpaste was also evaluated by the interpretation of the labels of four toothpastes of different brands and with different concentrations of fluoride. Associations between variables were tested using the Student's t test and one-way ANOVA. Level of OHL was associated with the amount of fluoride toothpaste deposited prior to the educational intervention (p = 0.021) and the percentage of approximation to the appropriate amount of fluoride toothpaste (p < 0.05). The choice of toothpaste was associated with schooling (p = 0.031). In conclusion, parents/guardians with adequate OHL better quantified fluoride toothpaste before and after the educational intervention and also came closer to the appropriate amount of toothpaste after the educational intervention. No significant differences in the final amount of toothpaste placed on the toothbrush were found among the intervention groups. The choice of the correct toothpaste was associated with a higher level of schooling.

Association Between Probable Awake Bruxism and School Bullying in Children and Adolescents: A Case-Control Study.

Purpose: The purpose of this study was to evaluate the association between probable awake bruxism (PAB) and school bullying in children and adolescents. Methods: A total of 380 children and adolescents enrolled in public and private schools in the city of Lavras, Minas Gerais, Brazil, participated in this case-control study. The case group (190 children with PAB) and the control group (190 children without PAB) were matched for sex and age. Data acquisition involved questionnaires administered to the children/adolescents and their parents/caregivers. An oral clinical examination to assess attrition tooth wear was also performed. Descriptive statistics and logistic regression analyses (95 percent confidence interval [95% CI], P<0.05) were conducted. Results: Among the 380 participants, 176 (46.3 percent) were male and 204 (53.7 percent) were female. Children and adolescents who were involved in bullying episodes as victims/bullies (odds ratio [OR] equals 2.92, 95% CI equals 1.07 to 7.95, P=0.036) and victims (OR equals 1.93, 95% CI equals 1.04 to 3.57, P=0.037) were significantly associated with PAB. Children and adolescents who reported sleep problems (OR equals 2.51, 95% CI equals 1.07 to 5.89, P=0.033) were significantly associated with PAB. Conclusion: Based on the results, it was observed that probable awake bruxism is associated with involvement in episodes of school bullying and sleep problems.

Association between the severity of possible sleep bruxism and possible awake bruxism and attrition tooth wear facets in children and adolescents.

OBJECTIVE: To evaluate the association between the severity of possible sleep bruxism (PSB) and possible awake bruxism (PAB) and attrition tooth wear facets (ATWF) in children/adolescents. METHODS: Four hundred-thirty-four children/adolescents enrolled in schools in Lavras, Brazil, participated in this cross-sectional study. Caregivers answered a questionnaire about their childrens' PSB. Children/adolescents answered a questionnaire about the occurrence of PAB. RESULTS: ATWF among individuals without PSB and PAB was lower than those with moderate/severe PSB (p = 0.038) and moderate/severe PAB (p = 0.003). ATWF in anterior teeth was lower among individuals without PSB compared to those with mild (p = 0.015) and moderate/severe PSB (p = 0.032). ATWF in posterior teeth was lower among individuals without PAB compared to those with mild (p = 0.046) and moderate/severe PAB (p = 0.017). CONCLUSION: The number of attrition tooth wear facets is proportional to the severity of PSB and PAB.

Possible sleep bruxism, smartphone addiction and sleep quality among Brazilian university students during COVID-19 pandemic.

Objectives: To evaluate the association of sleep bruxism activity with smartphone addiction and sleep quality among university students during COVID-19 pandemic. Material and Methods: A cross-sectional online survey with 546 university students in social distancing was conducted (May 29th to June 2nd 2020). Participants should be undergraduate and graduate students enrolled in Brazilian public/private universities. A self-completed questionnaire collected sociodemographic characteristics, academic information, and severity of possible sleep bruxism (PSB) activities (grinding, bracing, and thrusting). Students answered the Brazilian version of Pittsburgh sleep quality index (PSQI-BR) and short form of the smartphone addiction scale (SAS-SV). Descriptive statistics and multinomial logistic regression were performed (p=0.05). Results: Sample mean age was 24.9 (±5.5) years. Students with higher scores of PSQI-BR were more likely to present severe PSB-bracing (OR=1.154; 95%CI=1.057-1.260), severe PSB-grinding (OR=1.133; 95%CI=1.048-1.225) and severe PSB-thrusting (OR=1.197;95%CI=1.107-1.294). Students who had children presented 3 times more chance (OR=3.193; 95%CI=1.236-8.250) to report severe PSB-thrusting. Being female increased the chance of reporting moderate (OR=3.315; 95%CI=1.333-8.914) and severe (OR=2.940; 95%CI=1.116-7.747) PSB-thrusting. Students not enrolled in distance learning presented 2 times more chance (OR=2.638; 95%CI=1.233-5.649) of reporting moderate PSB-grinding. Students with higher scores in SAS-SV had a slight increase in the chance of presenting mild (OR=1.042; 95%CI=1.009-1.077) and moderate (OR=1.065; 95%CI=1.018-1.115) PSB-bracing, as well as mild (OR=1.044; 95%CI=1.011-1.078) and moderate (OR=1.041; 95%CI=1.005-1.077) PSB-thrusting. Conclusion: Smartphone addiction, worse sleep quality, having children, female sex and not being enrolled in distance learning were associated possible sleep bruxism during COVID-19 pandemic.

Cyberchondria and Associated Factors Among Brazilian and Portuguese Dentists.

Cyberchondria is a psychopathological behavior that affects people who compulsively consult the internet, by searching the symptoms of different pathologies from which they believe they are suffering, and when influenced by what they read, are sure they have some of these diseases. The aim of this study was to assess the cyberchondria level and associated factors among Brazilian and Portuguese dentists. A total 597 Brazilian and Portuguese dentists participated in this cross-sectional study. They were contacted via WhatsApp and asked to complete an online questionnaire on the Google Forms platform, from January 17 to 31, 2021, during the COVID-19 pandemic. Sociodemographic information was collected and cyberchondria was measured using the Portuguese language version of the Cyberchondria Severity Scale. Binary logistic regression models were used to estimate the unadjusted and adjusted Odds Ratio (OR) and corresponding 95% confidence interval (CI) for theassociationofcyberchondria and covariates. Each covariate was individually included in the regression model, and the unadjusted OR (95% CI) was estimated. Most participants were Brazilian (62.8%), women (75.5%), married (60.5%) and with children (55.6%). Average age was 42.1 years (+ 12.5). In the final model, it was found that with each increase of one year in age, the chance of a high level of cyberchondria decreased (OR=0.97; 95% CI 0.95-0.98). Brazilian dentists were 1.85 times more likely (95% CI 1.25-2.75) to have a high level of cyberchondria than Portuguese dentists. Women were 1.62 times more likely (95% CI 1.07-2.44) to have a high level of cyberchondria than men. It was concluded that young age, Brazilian nationality, and female gender favored the high level of cyberchondria among the participants in this sample during COVID-19 pandemic.

A cibercondria é um comportamento psicopatológico que atinge as pessoas que consultam compulsivamente a internet, pesquisando os sintomas das diferentes patologias de que acreditam estar sofrendo e, quando influenciadas pelo que leem, têm a certeza de possuir alguma dessas doenças. O objetivo deste estudo foi avaliar o nível de cibercondria e fatores associados entre dentistas brasileiros e portugueses. Participaram deste estudo transversal 597 dentistas brasileiros e portugueses. Eles foram contatados via WhatsApp e solicitados a preencher um questionário online na plataforma do Google Forms, no período de 17 a 31 de janeiro de 2021, durante a pandemia de COVID-19. Informações sociodemográficas foram coletadas e a cibercondria foi mensurada através da versão em língua portuguesa da Cyberchondria Severity Scale. Modelos de regressão logística binária foram usados para estimar a Odds Ratio (OR) não ajustada e ajustada e o intervalo de confiança(IC)de 95%correspondente para a associação de cibercondria e covariáveis. Cada covariável foi incluída individualmente no modelo de regressão, e o OR não ajustado (IC 95%) foi estimado. A maioria dos participantes eram brasileiros (62,8%), mulheres (75,5%), casados (60,5%) e com filhos (55,6%). A média de idade foi de 42,1 anos (+ 12,5). No modelo final, verificou-se que a cada aumento de um ano de vida, a chance de um nível elevado de cibercondria diminuía (OR = 0,97; IC95% 0,95-0,98). Os dentistas brasileiros tiveram 1,85 vezes mais probabilidade (IC95% 1,25-2,75) de apresentar alto índice de cibercondria quando comparados aos portugueses. As mulheres tinham 1,62 vezes mais probabilidade (IC 95% 1,07-2,44) de ter um alto nível de cibercondria em comparação com os homens. Concluiu-se que a idade mais jovem, a nacionalidade brasileira e o sexo feminino favoreceram o alto índice de cibercondria entre os participantes desta amostra durante a pandemia COVID-19.

Impact of the COVID-19 pandemic on sleep quality and sleep bruxism in children eight to ten years of age.

This study aimed to determine the impact of the COVID-19 pandemic on sleep quality and possible sleep bruxism (SB) in children eight to ten years of age. The study hypothesis was that sleep disturbances influenced a higher occurrence of bruxism during the COVID-19 pandemic. A longitudinal study was conducted at two time points: in person prior to the COVID-19 pandemic (T1), and online during the pandemic (T2). The sample comprised 105 children. Parents/caregivers answered a questionnaire addressing sociodemographic characteristics, the use of electronic devices, reported (vs. clinical) SB, and the Sleep Disturbance Scale for Children (SDSC) at both T1 and T2. McNemar's and Wilcoxon's tests were used to compare SB and sleep disorders at both time points. Poisson regression analysis determined the relative risk (RR) among the variables, and the incidence of possible SB (p≤0.05). The comparison of the two time points (T1 and T2) revealed a significant increase in possible SB (p<0.01) and sleep disorders (p < 0.04). Children whose parents had a lower schooling level (RR: 2.67; 95%CI: 1.19-6.01), those with their own electronic devices (RR: 1.97; 95%CI: 1.09-2.50), and those with sleep disorders during the pandemic (RR: 1.74; 95%CI: 1.35-2.24) were at greater risk of developing SB during the pandemic. Moreover, the incidence of bruxism and sleep disorders was greater during the pandemic. The factors influencing SB incidence during the pandemic were a lower level of mothers' schooling, greater access to electronic devices, and the occurrence of sleep disorders.
