RESUMEN
To evaluate the effect of acidic challenge on erosion depth and topographic characteristics of different materials used as occlusal sealants. Two hundred specimens of five sealant materials (Fuji IX, Ketac Molar, Fuji II, Equia and Clinpro) and forty bovine teeth enamel samples (control) were prepared and exposed to acidic challenge. The specimens were immersed in four different solutions (orange juice, coke drink, citric acid or distilled water) under mildly shaken conditions for 3 days. The erosion depth profiles were measured using a profilometer and Scanning Electron Microscope (SEM). Two-way ANOVA with Tukey post-hoc test was performed to evaluate the interactions. Sealant material and acidic challenge had significant effects on erosion depth. Among the materials, Fuji II presented the highest mean of erosion depth after immersion in orange juice, coke drink, and citric acid. All materials groups presented higher erosion depth values after immersion in the citric acid solution, except Clinpro. Bovine enamel presented higher erosion depth values compared to all materials when submitted to erosive challenge. Sealant materials submitted to the acidic challenge presented different degrees of erosion and topographic modification; however, they are less susceptible to erosion than bovine teeth enamel.

PURPOSE: To evaluate the direct and indirect pathways between cavitated carious lesions and oral health-related quality of life (OHRQoL) during the transition from childhood to adolescence. METHODS: A prospective cohort study followed an initial sample of 639 children (one to five years old), in southern Brazil for ten years. In addition to the baseline (T1), two subsequent reassessments were conducted after seven (T2) and ten years (T3). OHRQoL was measured through the Early Childhood Oral Health Impact Scale (ECOHIS) and Child Perceptions Questionnaire (CPQ8-10 and CPQ11-14), according to the age group. Dental caries was evaluated using the International Caries Detection and Assessment System (ICDAS) in the three waves. Socioeconomic variables and other factors related to oral health (frequency of toothbrushing and toothache) were also collected. Structural equation modeling was used to estimate the direct and indirect effects among the variables over ten years. RESULTS: A total of 449 and 429 children were reevaluated at T2 and T3 (positive response rates of 70.3% and 67.1%, respectively). Dental caries in T1 and T2 directly predicted the occurrence of a worse OHRQoL in the respective follow-up periods. Dental caries at T3 indirectly predicted a worse OHRQoL (T3), via toothache. Dental caries at T1 and T2 directly predicted the occurrence of dental caries at T3, while a worse OHRQoL at T2 directly predicted a worse OHRQoL at T3. CONCLUSION: Dental caries negatively impacts, directly and indirectly, the OHRQoL from early childhood to adolescence.

AIM: To assess the immediate and late effects of the COVID-19 pandemic on the oral health-related quality of life (OHRQoL) of adolescents. DESIGN: This is a longitudinal study performed with adolescents (11-15 years old) from Southern Brazil who were evaluated before the COVID-19 outbreak, and 3 (T2) and 15 (T3) months after the beginning of the pandemic. OHRQoL was assessed using the CPQ11-14. Sociodemographic and clinical variables were also collected. Changes in OHRQoL before, 3 and 15 months after the start of the pandemic were analyzed through multilevel Poisson regression models for repeated measures. RESULTS: A total of 290 adolescents were evaluated at T1, 207 were re-evaluated at T2, and 204 at T3. Overall CPQ11-14 scores over follow-ups were 11.0 (SD 8.0) at T1, 8.3 (SD 7.8) and 12.8 (SD 8.8) at T3. Compared to T1, adolescents presented 29% lower overall CPQ11-14 scores (IRR 0.71 95% CI 0.66-0.75) at T2, and 11% higher scores at T3 (IRR 1.11 95% CI 1.05-1 0.17), especially for the emotional and social well-being domains. CONCLUSION: COVID-19 pandemic impacted the adolescents' OHRQoL differently over time, indicating a reduction in impacts immediately after the beginning and worsening over long term exposure to this scenario.
RESUMEN
OBJECTIVE: The aim of this study was to evaluate the extent to which orthodontic treatment need is perceived by the patients and by the orthodontist, as well as the possible impacts on the OHRQoL (Oral Health-Related Quality of Life) over the course of conventional orthodontic treatment in adolescent patients. METHODS: The sample consisted of 55 adolescents. The perception of patients and orthodontists relative to the malocclusion was evaluated by the IOTN (Index of Orthodontic Treatment Need). The OHRQoL was evaluated by the Child-OIDP (Child-Oral Impacts on Daily Performances) questionnaire before the conventional orthodontic appliance was bonded (T0); and at the following time intervals: after one week (T1), one month (T2), three months (T3), six months (T4), and after the end of orthodontic treatment (T5). RESULTS: Adolescents who had large orthodontic treatment needs had a poor OHRQoL, according to their self-perception (p=0.003) and according to the orthodontist's perception (p<0.001), when compared with patients with small and moderate needs. There was statistically significant difference in the OHRQoL between the time intervals T0 and T1 (p=0.021), T2 and T3 (p<0.001), T3 and T4 (p=0.033), and T0 and T5 (p<0.002). At the end of treatment, all evaluated participants reported an improvement in OHRQoL. CONCLUSIONS: It was concluded that adolescents and orthodontists agreed with regard to the perception of orthodontic treatment need. In the first week and in the first month of orthodontic treatment, there was a negative impact on the OHRQoL. After three months, an improvement of OHRQoL was detected, which has progressed over time.

This study aimed to evaluate trends in the prevalence of dental caries in preschool children and associated factors considering different time variations. This is a time series study performed using data from three cross-sectional studies with pre-school children from southern Brazil in 2008, 2013 and 2019. This children group was born between the years of 2003 to 2018. Dental caries was evaluated by decayed, missing and filled deciduous teeth (dmft index). Demographic, socioeconomic, behavioural and psychosocial variables were also collected. Chi-square test for trends and a hierarchical age-period-cohort (HAPC) analysis using multilevel Poisson regression model for testing the associations between predictor variables and dental caries experience were used. A total of 1,644 pre-school children participated in all surveys. There was a significant difference in caries experience considering all APC effects. The prevalence of dental caries was 25.0% in 2008, 16.3% in 2013, and 19.4% in 2019 (p < 0.01) and no statistical difference was observed. An age effect showed that older children were more likely to experience dental caries. Considering the cohort effect, there is a significant difference between the generations, mainly between 2003 and 2018. Household income, use of dental services, and parent's perception of child oral health were associated with dental caries experience no matter the time variation. Despite recent declines in dental caries prevalence among preschool children, caries levels increased with age and social inequalities persisted through the years, indicating a need of reviewing the policies to reduce the burden of this oral disease.

OBJECTIVE: To assess the impact of the consumption of licit and illicit substances on the oral health-related quality of life (OHRQoL) of adolescents from public schools in the south of Brazil. METHODS: This cross-sectional study was carried out with a random sample of adolescents aged between 17 and 18 years old from Santa Maria, Brazil. The consumption of licit and illicit substances was measured through a self-administered questionnaire with questions from the National Survey of Scholar Health. The OHRQoL was collected using the Brazilian short version of Child Perceptions Questionnaire 11-14 (CPQ11-14). Multilevel Poisson regression models were used to estimate the association between the outcome and the explanatory variables where the adolescents (first level) were nested in their schools (second level). RESULTS: A total of 768 adolescents were evaluated. Of these, about 15.6% have already used illegal substances. Adolescents who reported the use of illicit substances had 28% higher CPQ11-14 scores when compared to their counterparts. Alcohol use was also related to worse levels of OHRQoL, while the consumption of cigarettes acted as a protective factor. CONCLUSIONS: This study found an association between the use of alcohol and illicit drugs with worse levels of OHRQoL.

OBJECTIVES: The primary aim of this study was to evaluate if children's oral health and oral health-related quality of life (OHRQoL) were associated with school performance. Moreover, the study aimed to examine whether school environment factors influenced this association. METHODS: This cross-sectional study was based on a population-based sample of 998 12-year-old schoolchildren from 31 public schools in Quito, Ecuador. Trained and calibrated examiners conducted clinical exams for dental caries, dental trauma and malocclusion. Furthermore, children completed the Spanish version of the Child Perception Questionnaire (CPQ11-14 ), and their parents answered questions about socio-economic status. School coordinators provided information on the physical environment, promotion of health practices and the occurrence of negative episodes in the school. There were three outcomes: grades obtained in Spanish language and mathematics and the number of missed school days. Multilevel linear and Poisson regression models were conducted using a hierarchical approach to include the variables guided by a previously created direct acyclic graph. RESULTS: Children with dental trauma and higher CPQ11-14 scores showed lower grades and school attendance. Schoolchildren from schools with episodes of vandalism had more school days missed. CONCLUSION: The school performance of 12-year-old children is affected by dental trauma and by a worse OHRQoL, as well as a negative school environment. Therefore, supportive environments and promoting health measures in schools could overcome this worse academic performance in children with oral health problems.

OBJECTIVES: To examine the extent to which the effect of income inequalities on tooth loss is attributable to differential exposure and susceptibility to heavy drinking in older Brazilian adults. METHODS: We conducted a secondary analysis using data from The Brazilian Longitudinal Study of Ageing (ELSI-Brazil 2015-2016), a nationally representative sample of community-dwelling people aged 50 years and over. Causal mediation analysis based on the counterfactual outcome framework decomposed the effect of income on tooth loss mediated by heavy drinking into four components (four-way decomposition): controlled direct effect (neither mediation nor interaction), reference interaction (interaction only), mediated interaction (both mediation and interaction) and pure indirect effect (mediation only). Proportions of effect attributable to each component were calculated to estimate the differential exposure (the sum of the third and fourth components) and differential susceptibility (the sum of the second and third components) to heavy drinking. RESULTS: The analytical sample comprised 8114 participants. After adjusting for covariates, 7.3% (95% CI: 3.8%; 10.9%) and -39.5% (95% CI: -75.8%; -3.3%) of the effects of income on tooth loss were attributable to differential exposure and susceptibility to heavy drinking, respectively, consistent with the alcohol harm paradox. When setting non-functional dentition as outcome, only the effect of differential susceptibility remained (-81.7% [95% CI: -128.2%; -35.2%]). CONCLUSION: Our findings suggest that individuals of low-income groups appear to be more susceptible to the effects of heavy drinking on tooth loss.

AIM: The aim of this randomized clinical trial was to compare the impact of two management options for primary molars with pulp necrosis (pulpectomy or extraction) on children's oral health-related quality of life (OHRQoL). DESIGN: A total of 100 children aged 3-5 years with at least one necrotic primary molar were selected and randomized into the study groups. The Brazilian version of early childhood oral health impact scale (B-ECOHIS) was completed by the parent proxy reports at baseline and after 4, 8 and 12 months. Differences between the trial groups were assessed through bootstrap linear regression for B-ECOHIS scores, logistic regression for dental pain self-reports and anxiety scores (α = 5%). RESULTS: The mean (SD) B-ECOHIS scores at baseline and after 12 months were 17.7 (6.5) and 3.0 (4.0) in the pulpectomy group and 18.8 (7.7) and 7.9 (7.7) in the extraction group. Both treatments significantly improved OHRQoL, but tooth extraction group showed higher scores in total B-ECOHIS (p < .001) and most domains, indicating lower OHRQoL. Furthermore, higher anxiety levels were reported for dental extraction compared to pulpectomy (OR = 2.52; p = .008). CONCLUSION: Pulpectomy resulted in an improved OHRQoL scores after 12 months when compared to tooth extraction and should be considered as the treatment of choice for necrotic primary molars.

BACKGROUND: Investigations assessing how oral health status affects school performance and attendance considering individual and community variables are lacking. AIM: To analyze the association of school contextual factors and oral conditions with school performance and absenteeism in early adolescence. DESIGN: This cross-sectional study was carried out with 593 12-year-old students from 20 schools in Passo Fundo, a southern city in Brazil. The caregivers provided sociodemographic information by means of a questionnaire. Oral health status was clinically examined for dental caries and gingival bleeding. Students answered the CPQ11-14 questionnaire to assess the oral health-related quality of life (OHRQoL). Information on contextual factors was obtained from the schools' administrators. "School performance" was measured by Portuguese and Mathematic tests' scores, and "school absenteeism" by the number of school days missed. Descriptive statistics was conducted, followed by unadjusted and adjusted multilevel linear regression. RESULTS: At the individual level, low OHRQoL was associated with lower school performance and higher absenteeism. At the contextual level, students from private schools had higher school performance and lower mean of school days missed. CONCLUSIONS: The type of school and OHRQoL were associated with school performance and attendance of adolescents.

RESUMO Objetivo: O objetivo deste estudo foi avaliar o quanto a necessidade de tratamento ortodôntico é percebida pelos pacientes e pelo ortodontista, bem como os possíveis impactos na Qualidade de Vida Relacionada à Saúde Bucal (QVRSB) ao longo do tratamento ortodôntico convencional em pacientes adolescentes. Métodos: A amostra foi composta por 55 adolescentes. A percepção dos pacientes e ortodontistas em relação à má oclusão foi avaliada pelo Índice de Necessidade de Tratamento Ortodôntico (IOTN). A QVRSB foi avaliada pelo questionário Child-OIDP (Child-Oral Impacts on Daily Performances) antes da colagem do aparelho ortodôntico convencional (T0); e nos seguintes intervalos de tempo: após uma semana (T1), um mês (T2), três meses (T3), seis meses (T4) e após o término do tratamento ortodôntico (T5). Resultados: Adolescentes que apresentavam grandes necessidades de tratamento ortodôntico apresentaram baixa QVRSB, segundo sua autopercepção (p=0,003) e segundo a percepção do ortodontista (p<0,001), quando comparados com pacientes com necessidades pequenas e moderadas . Houve diferença estatisticamente significativa na QVRSB entre os intervalos de tempo T0 e T1 (p=0,021), T2 e T3 (p<0,001), T3 e T4 (p=0,033) e T0 e T 5 (p<0,00 2 ). Ao final do tratamento, todos os participantes avaliados relataram melhora na QVRSB. Conclusões: Concluiu-se que adolescentes e ortodontistas concordaram quanto à percepção da necessidade de tratamento ortodôntico. Na primeira semana e no primeiro mês de tratamento ortodôntico, houve impacto negativo na QVRSB. Após três meses, foi detectada uma melhora na QVRSB, que progrediu ao longo do tempo.

RESUMEN
This study aimed to explore the pathways that can influence cigarette smoking among adolescents. This population-based cohort followed a random sample of 12-year-old adolescents from southern Brazil for 6 years. Regular cigarette smoking was assessed through a self-reported question, previously used in the Brazilian National Survey of Scholar Health. We also gathered data on bullying, dental caries at baseline, incidence of caries, sex, friend network, and Sense of Coherence (SOC). Socioeconomic and demographic characteristics were also collected. Structural equation modeling was used to evaluate the pathways. Of the 1,134 adolescents examined at baseline, 768 were re-evaluated (67.7% retention rate). The prevalence of smoking was 37.6%. This prevalence was directly affected by low SOC (SC: -0.14, p < 0.01), low household income (SC: -0.12, p < 0.01), and male sex (SC: 0.15, p < 0.01). Presence of dental caries at baseline indirectly influenced the occurrence of dental bullying at follow-up via the incidence of dental caries (SC: 0.01, p < 0.05). Dental bullying indirectly influenced cigarettes consumption via SOC (SC: 0.62, p < 0.05). Friend network also indirectly influenced the consumption of cigarettes via SOC (SC: 0.32, p < 0.05). Psychosocial factors influence adolescent cigarette consumption through its higher direct and indirect effects (via bullying). In addition, behavioral, sociodemographic, and clinical factors also influence the occurrence of smoking.

AIM: To evaluate the immediate and late impact of the COVID-19 pandemic on the occurrence of possible sleep bruxism (SB) among adolescents in Brazil. DESIGN: This is a longitudinal study performed with adolescents (11-15 years old) from Southern Brazil. Baseline data were collected before the Brazilian COVID-19 outbreak (T1). Posteriorly, data were collected after 3 (T2) and 15 months under the Brazilian COVID-19 outbreak. The possible SB was evaluated by the question: 'Do you grind your teeth during your sleep?'. Sociodemographic, psychosocial and clinical variables were also collected. Changes in SB were evaluated by multilevel logistic regression models for repeated measures. RESULTS: Of the 290 adolescents assessed at T1, 182 were reassessed at both follow-ups. The prevalence of possible SB was 13% at T1, 11% at T2 and 22% at T3. There were no immediate effects of the COVID-19 pandemic on the occurrence of possible SB (T2). Adolescents had odds 2.77 times greater of presented possible SB after 15 months (T3) of COVID-19 pandemic scenarios when compared to T1. CONCLUSION: There was a considerable and late increase in the possible SB in adolescents in Brazil during the COVID-19 pandemic.
RESUMEN
This study aimed to investigate the impact of school bullying and oral health-related verbal bullying on the occurrence of bruxism associated with poor sleep quality among adolescents. This cross-sectional study was nested in a cohort study performed with a sample of children from southern Brazil. Possible sleep bruxism was determined by the question: "Has anyone told you that you grind your teeth in your sleep?" Sleep quality was determined by answering the following question: "How would you classify the quality of your sleep?". The outcome was created by combining occurrence of sleep bruxism and poor sleep quality. The Sense of Coherence (SOC) was assessed using the SOC-13 scale. Bullying was investigated using the victim scale of the Olweus Bullying Questionnaire and oral health-related verbal bullying using an item from the Child Perceptions Questionnaire-11-14. Demographic, socioeconomic, psychosocial, and clinical data were also collected. Poisson regression models with robust variance were used. Results were expressed as prevalence ratio (PR) and 95% confidence intervals (95% CI). A total of 429 adolescents with a mean age of 12.6 (standard deviation 1.3) years were evaluated. The prevalence of bruxism associated with poor sleep quality was 23.7%. Victims of school bullying (PR 2.06; 95%CI: 1.01-4.22) and oral health-related verbal bullying (PR 1.87; 95%CI: 1.18-2.95) presented higher prevalence of bruxism associated with poor sleep quality. Factors such as skin color and SOC were also associated with the outcome. These findings suggest an association between episodes of bullying and bruxism related to poor sleep quality.

OBJECTIVES: To evaluate predictors for caries incidence on first permanent molars and to assess the accuracy and efficiency of these predictors for the indication of pit and fissure sealants. METHODS: This 7-y cohort study started in 2010 with a sample of 639 children (1-5 years) from Southern Brazil. Dental caries was assessed using the ICDAS. Maternal education, family income, parental perception on child oral health and severe dental caries experience were collected at baseline and used to test the prediction of dental caries. Predictive values, accuracy and efficiency were estimated for each possible predictor. RESULTS: 449 children were re-assessed at follow-up (70.3% retention rate). The baseline characteristics showed similar risks for dental caries incidence in first permanent molars. Low family income and poor parental perception of child oral health were moderately accurate in correctly identifying sound children who would not need to receive pit and fissure sealant. However, all the adopted criteria have lower accuracy incorrectly identifying children who later developed dental caries in first permanent molars. CONCLUSIONS: Distal and intermediate factors were relatively accurate in determining caries risk incidence on children's first permanent molars. The criteria adopted were more accurate in identifying sound children than those who need to receive pit and fissure sealant. CLINICAL RELEVANCE: Our findings reinforce the idea that investing in strategies that take into account common risk factors still represents the best option for dental caries prevention. However, adopting only these parameters is not enough to indicate pit and fissure sealants.

This study evaluated the relationship of structural and cognitive dimensions of social capital with oral health-related quality of life (OHRQoL) among adolescents. This was a cross-sectional study nested in a cohort of adolescents from southern Brazil. OHRQoL was evaluated using the short version of the Child Perceptions Questionnaire 11-14 (CPQ11-14). Structural social capital was measured by attendance of religious meetings and social networks from friends and neighbours. Cognitive social capital was evaluated through trust in friends and neighbours, perception of relationships in the neighbourhood, and social support during hard times. Multilevel Poisson regression analysis was performed to estimate the association between social capital dimensions and overall CPQ11-14 scores; higher scores corresponded to worse OHRQoL. The sample comprised 429 adolescents with a mean age of 12 years. Adolescents who attended religious meetings less than once a month or never presented higher overall CPQ11-14 scores. Adolescents who did not trust their friends and neighbours, those who believe that their neighbours did not have good relationships, and those reporting no support during hard times also presented higher overall CPQ11-14 scores. OHRQoL was poorer in individuals who presented lower structural and cognitive social capital, with the greatest impact related to the cognitive dimension.

OBJECTIVE: To assess the pathways in which oral health conditions, socioeconomic, and psychosocial factors in childhood can lead to the occurrence of bullying in adolescence. METHODS: This is a 10-year cohort study conducted with a sample of 639 children in southern Brazil. Oral health conditions (dental caries, dental trauma and malocclusion), sociodemographic and psychosocial characteristics were obtained at baseline (T1) and at follow-up (T2). General and dental bullying were assessed at T2 using the Bullying Olweus questionnaire and through a question contained in the Child Perception Questionnaire 11-14. Structural equation modelling was used to evaluate the pathways between oral health measures and bullying episodes over time. RESULTS: A total of 429 students were evaluated at follow-up. Untreated dental caries were direct and indirectly related with the occurrence of dental bullying at follow-up and indirectly associated with general bullying at T2. Low socioeconomic status, low sense of coherence and dental bullying presented a direct impact on the occurrence of general bullying at T2. CONCLUSIONS: Untreated dental caries are presented as the main oral health predictor of the occurrence of bullying episodes in adolescence.
RESUMEN
BACKGROUND: Dental fear affects children's oral health; there is, however, no evidence regarding the pathways linking possible predictors for its occurrence. AIM: This study aimed at exploring the direct and indirect effects of sociodemographic, clinical, behavioural and psychosocial factors on the development of dental fear in schoolchildren over time. DESIGN: This is a prospective cohort study, with 10 years of follow-up. The first assessment started in 2010 (T1) with a sample of 639 children aged 1-5 years from Southern Brazil. For this study, the follow-up (T2) of these individuals was performed in 2020. Dental fear was assessed at T2 using the Brazilian version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Socio-economic, demographic, psychosocial and oral health measures were collected in both assessments. A structural equation model was performed to assess the direct and indirect pathways among variables at T1 and T2 to predict the CFSS-DS scores at T2. RESULTS: Of the 639 children, 429 were re-evaluated at T2. Higher levels of untreated dental caries, younger individuals, dental visits for nonroutine reasons and low sense of coherence at T2 directly impacted dental fear at T2. Considering the indirect effects, the presence of dental caries and low household income at T1 indirectly impacted higher levels of dental fear over 10 years via dental caries at follow-up. CONCLUSION: Our findings suggest that socio-economic, demographic, clinical, psychosocial and behavioural conditions can influence dental fear from childhood to adolescence.
