Contextual and individual factors associated with traumatic dental injuries in deprived 12-year-old schoolchildren: A cohort study.

AIM: Traumatic dental injuries (TDIs) among children and adolescents have been acknowledged as of public health concern worldwide. The aim of the study was to assess the relationship between contextual and individual characteristics and TDIs in 12-year-old schoolchildren. MATERIALS AND METHODS: A cohort study was conducted with 355 schoolchildren living in deprived communities in the city of Manaus, Brazil. Contextual factors (place of residence and socio-economic indicators) and individual characteristics, including sex, family income, parents/guardians years of schooling, overjet and open bite (Dental Aesthetic Index), self-esteem (Rosenberg Self-Esteem Scale), sense of coherence (Sense of Coherence Scale), oral health beliefs, social support (Social Support Appraisals) were assessed at baseline. TDIs were measured at baseline and at 2-year follow-up using the O'Brien Index. Data were analysed through confirmatory factor analysis and structural equation modeling. RESULTS: The baseline prevalence of TDIs was 17.6% and the incidence of TDIs at 2-year follow-up was 26.8%. Better psychosocial status had a direct protective effect on the incidence of TDIs (ß = -.184). Better contextual characteristics (ß = -.135) and greater overjet (ß = -.203) were directly associated with poor psychosocial status. Higher schooling of parents/guardians directly predicted better psychosocial status (ß = .154). Psychosocial status mediated the relationship of greater overjet (ß = .036), contextual factors (ß = .024) and parental/guardian schooling (ß = -.027) with TDIs. CONCLUSIONS: Contextual factors and individual characteristics predicted TDIs. Psychosocial status was a relevant individual attribute in the causal network of TDIs, due to the direct effect on the incidence of TDIs as well as a mediator on the influence of contextual factors, overjet and parents/guardians schooling on the incidence of TDIs.

The association between malocclusion and health-related quality of life in adolescents: A mediation analysis.

This study investigated the role of oral health-related functional limitations and social well-being, self-perceived health, psychosocial factors, and social support in mediating the impact of malocclusion on health-related quality of life (HRQoL). A school-based 6-month cohort study was conducted with 376 12-year-old deprived adolescents. Measures at baseline included malocclusion (DAI score), dental caries, sociodemographic characteristics, psychosocial traits (self-esteem, sense of coherence, oral health beliefs), and social support. The oral health-related functional limitations and symptoms (social well-being) domains of the CPQ11-14 , self-perceived health, and HRQoL (Kiddo-KINDL) were evaluated at the 6-month follow-up. Associations between observed and latent variables (social support, psychosocial factors, and HRQoL) were evaluated using structural equation modelling, according to the Wilson and Cleary theoretical model. Malocclusion was indirectly associated with worse HRQoL, mediated by functional limitations, social well-being, and self-perceived health. Better psychosocial status was directly associated with better HRQoL, and higher social support was indirectly associated with better HRQoL via psychosocial factors. Dental caries experience, female sex, and lower family income were indirectly associated with worse HRQoL. The impact of malocclusion on HRQoL was mediated by oral health-related functional limitations, social well-being, and self-perceived health. Sociodemographic and psychosocial factors, and social support also impacted HRQoL.

Prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous populations in Brazil: a systematic review and meta-analysis.

The aim of this review was to evaluate the prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous in Brazil. A systematic review of observational studies was performed according to the PRISMA guidelines (CRD42020218704). The search strategy involved the electronic databases of Embase, LILACS, PubMed, Web of Science, Scopus, and the CAPES Theses and Dissertations for gray literature. The eligibility criteria consisted of publications that assessed the prevalence of oral conditions in indigenous populations in Brazil. Studies with indigenous people living in urban area were excluded. The risk of bias was evaluated by using JBI Critical Appraisal for prevalence studies. Thirty studies were included in the review, and the majority showed a low risk of bias. A meta-analysis of 20 studies was conducted using the random-effects model and a 95% confidence interval. Several ethnicities were studied in isolation or in groups (n = 7,627 for dental caries; n = 2,774 for periodontal disease; n = 1,067 for malocclusion; n = 150 for tooth wear). The prevalence of caries ranged from 50% among indigenous people aged 18-36 months to 100% among those aged 65-74 years. The prevalence of periodontal disease ranged from 58% to 83%. The prevalence of malocclusion was 43%. Tooth wear was assessed in only one ethnic group and showed a prevalence of 100% in indigenous people aged >18 years. The certainty of evidence assessed by the GRADE system ranged from very low to moderate. This systematic review showed significant differences in the prevalence of dental caries, periodontal disease and malocclusion between indigenous population groups and territories in which indigenous people live.

Socio-economic status, psychosocial factors, health behaviours and incidence of dental caries in 12-year-old children living in deprived communities in Manaus, Brazil.

OBJECTIVES: This study examines the relationships between socio-economic status, psychosocial factors, health-related behaviours and the incidence of dental caries amongst 12-year-old schoolchildren living in deprived communities in Manaus, Brazil. METHODS: A longitudinal study involving 312 children aged 12 years was conducted in the city of Manaus, Brazil. Baseline data including socio-economic status (number of goods, household overcrowding, parents' schooling, family income), psychosocial factors (sense of coherence [SOC-13], social support [Social Support Appraisals questionnaire]) and health-related behaviours (frequency of toothbrushing, sugar consumption, sedentary behaviour) were collected through structured questionnaires. The number of decayed teeth was clinically assessed at baseline and one-year follow-up. A hypothesised model evaluating the direct and indirect pathways between the variables was tested using confirmatory factor analysis and structural equation modelling. RESULTS: The incidence of dental caries at the one-year follow-up was 25.6%. Sugar consumption (ß = 0.103) and sedentary behaviour (ß = 0.102) directly predicted the incidence of dental caries. A higher socio-economic status was directly linked with lower sugar consumption (ß = -0.243) and higher sedentary behaviour (ß = 0.227). Higher social support directly predicted lower sugar consumption (ß = -0.114). Lower socio-economic status (ß = -0.046) and lower social support (ß = -0.026) indirectly predicted the incidence of dental caries via sugar consumption and sedentary behaviour. CONCLUSIONS: In the population studied, sugar consumption and sedentary behaviour are meaningful predictors of the incidence of dental caries amongst schoolchildren living in deprived communities. Indirect pathways of lower socio-economic status and low social support with dental caries incidence via sugar consumption and sedentary behaviour were detected. These findings should be considered in oral interventions and oral health care policies to prevent dental caries amongst children living in deprivation. CLINICAL SIGNIFICANCE: Social conditions, social support, sedentary behaviour and sugar consumption directly influence dental caries in children.

There was consensus on the use of 2% sodium hypochlorite as an irrigating solution and on the choice of calcium hydroxide as the basis for intracanal medication. It is concluded that the courses have convergence of the Endodontics teaching model, mainly in the foundations of the specialty, which are the integration with other disciplines, the workload, the treatment goals, the syllabus and the presentation of new technologies (AU).

Conhecimento de acadêmicos de Odontologia sobre o uso de anestésicos locais / Conocimiento de los estudiantes de odontología sobre el uso de anestésicoslocales / Dentistry students' knowledge about the use of local anesthetics

O presente estudo teve como objetivo avaliar o conhecimento de estudantes de graduação do curso de Odontologia em relação à indicação e uso dos anestésicos locais nos procedimentos clínicos e cirúrgicos. Trata-se de um estudo prospectivo, observacional tendo como instrumento de coleta um questionário composto de perguntas abertas e fechadas sobre a temática. Após assinatura do termo de consentimento livre e esclarecido, 59 acadêmicos que obedeciam aos critérios de inclusão e exclusão participaram do estudo respondendo ao questionário. A amostra apresentou média de idade de 22,75 anos, 17 (29,31%) eram do sexo masculino e 41 (70,68%) do feminino, sendo que um participante não declarou o sexo. A média de tempo cursando Odontologia foi de 4 anos, sendo que 19 alunos (31%) cursavam o 6º período, 22 (37,9%) o 8º período e 18 (31%) o 10º período do curso. Situações relacionadas à toxicidade do anestésico foram corretamente identificadas por 20 participantes (57,2% dos 35 que responderam à pergunta), 56 (94,9%) realizaram anamnese direcionada e 55 (93,2%) fizeram a escolha do sal anestésico de acordo com a condição sistêmica do paciente. Porém, quando questionados sobre a dose anestésica máxima em determinada situação clínica, apenas 6 (10,2%) responderam corretamente. Considerando a disponibilidade de anestésicos para uma exodontia simples em paciente hipertenso ou diabético controlado, gestante, lactante e criança, pouco mais que a metade dos alunos (62,7% a 52,5%) souberam indicar corretamente solução anestésica,considerando a lidocaína com vasoconstritor o anestésico de escolha. Foram observadas diferenças estatisticamente significativas quando comparado o gênero dos acadêmicos em relação ao uso de anestésico tópico (p=0,018) e uso de anestesia local para o procedimento de raspagem periodontal subgengival (p = 0,008), sendo as duas indicações mais comuns na parcela feminina da amostra. Conclui-se que a maioria dos acadêmicos possui conhecimentos necessários para escolha do sal anestésico e sucesso quanto ao emprego da técnica, entretanto não realizaram de forma correta o cálculo da dose máxima recomendada diante de uma situação clínica hipotética, necessitando, neste e em outros parâmetros, de revisão de conceitos, procedimentos e condutas clínicas (AU).

Se trata de un estudio observacional prospectivo que utiliza como instrumento de recogida de datos un cuestionario compuesto por preguntas abiertas y cerradas sobreel tema. Después de firmar el formulario de consentimiento libre e informado, 59 estudiantes que cumplieron con los criterios de inclusión y exclusión participaron en el estudio respondiendo el cuestionario. La muestra tenía una edad media de 22,75 años, 17 (29,31%) eran del sexo masculino y 41 (70,68%) del sexo femenino, y un participante no declaró el sexo. El tiempo promedio de estudio de Odontología fue de 4 años, con 19 alumnos (31%) cursando el 6° período, 22 (37,9%) el 8° período y 18 (31%) el 10° período de la carrera. Las situaciones relacionadas con la toxicidad del anestésico fueron identificadas correctamente por 20 participantes (57,2% de los 35 que respondieron la pregunta), 56 (94,9%) realizaron anamnesis dirigida y 55 (93,2%) eligieron la sal del anestésico según el estado sistémico del paciente. Sin embargo, cuando se les preguntó sobre la dosis máxima de anestésico en una situación clínica dada, solo 6 (10,2%) respondieron correctamente. Considerando la disponibilidad de anestésicos para una extracción dental simple en pacientes hipertensos o diabéticos controlados, gestantes, lactantes y niños, poco más de la mitad de los estudiantes (62,7% a 52,5%) sabían indicar correctamente la solución anestésica, considerando la lidocaína con vasoconstrictor el anestésico de elección. Se observaron diferencias estadísticamente significativas al comparar el sexo de los estudiantes en relación con el uso de anestésico tópico (p=0,018) y uso de anestesia local para el procedimiento de raspado periodontal subgingival (p=0,008), las dos indicaciones más comunes en la porción femenina de la muestra. Se concluye que la mayoría de los académicos tienen los conocimientos necesarios para elegir la sal anestésica y lograr el uso de la técnica, sin embargo, no calcularon correctamente la dosis máxima recomendada en una situación clínica hipotética, requiriendo, en este y otros parámetros, revisar conceptos, procedimientos y enfoques clínicos (AU).

The objective of the present study was to evaluate the knowledge of undergraduate dental students regarding the indication and use of local anesthetics in clinical and surgical procedures. This is a prospective, observational study, using a questionnaire with open and closed questions about the subject as a collection tool. After signing the ICF, 59 students who met the inclusion and exclusion criteria participated in the study by answering the questionnaire. The students included in the study had a mean age of 22.75 years, 29.31% (n=17) were male and 70.68% (n=41) were female, and one student did not declare. The average number of years in college was 4 years, with 19 students (31%) in 6th period, 22 (37.9%) in 8th period and 18 (31%) in 10th period. Fifty-seven percent identified situations related to anesthetic toxicity, 94.9% performed directed anamnesis, and 93.2% chose the anesthetic salt according to the general condition of the patient. However, when questioned about the maximum anesthetic dose in a given clinical situation, only 10.2% answered correctly. For anesthetic application procedures, 89.8% considered that controlling the volume of anesthetic solution injected was an important factor, and 72.9% informed that prior aspiration was done before starting the injection of the anesthetic. Regarding the success of the technique, 78% reported success. Considering the availabilityof anesthetics, the indication for patients with some systemic condition, 62.7% knew how to correctly indicate the anesthetic solution. Statistically significant differences were observed when comparing the gender of the students regarding the use of topical anesthetic (p = 0.018) and the use of local anesthesia for subgingival periodontal scaling (p = 0.008), both indications being more common in female students. It was concluded that most of the students had the necessary knowledge to choose the anesthetic salt and were successful in using the technique, however, they did not correctly calculate the maximum dose recommended for a clinical situation presented as an assumption, requiring, in this and other parameters, a review of concepts, procedures, and clinical conducts (AU).

Prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous populations in Brazil: a systematic review and meta-analysis

Abstract The aim of this review was to evaluate the prevalence of dental caries, periodontal disease, malocclusion, and tooth wear in indigenous in Brazil. A systematic review of observational studies was performed according to the PRISMA guidelines (CRD42020218704). The search strategy involved the electronic databases of Embase, LILACS, PubMed, Web of Science, Scopus, and the CAPES Theses and Dissertations for gray literature. The eligibility criteria consisted of publications that assessed the prevalence of oral conditions in indigenous populations in Brazil. Studies with indigenous people living in urban area were excluded. The risk of bias was evaluated by using JBI Critical Appraisal for prevalence studies. Thirty studies were included in the review, and the majority showed a low risk of bias. A meta-analysis of 20 studies was conducted using the random-effects model and a 95% confidence interval. Several ethnicities were studied in isolation or in groups (n = 7,627 for dental caries; n = 2,774 for periodontal disease; n = 1,067 for malocclusion; n = 150 for tooth wear). The prevalence of caries ranged from 50% among indigenous people aged 18-36 months to 100% among those aged 65-74 years. The prevalence of periodontal disease ranged from 58% to 83%. The prevalence of malocclusion was 43%. Tooth wear was assessed in only one ethnic group and showed a prevalence of 100% in indigenous people aged >18 years. The certainty of evidence assessed by the GRADE system ranged from very low to moderate. This systematic review showed significant differences in the prevalence of dental caries, periodontal disease and malocclusion between indigenous population groups and territories in which indigenous people live.

Subjective oral health measures in caregivers of patients with autism spectrum disorder and down syndrome: a preliminary study

This study aimed to address the subjective oral health measures of caregivers of individuals with autism spectrum disorder (ASD) and Down syndrome. This cross-sectional study included 15 caregivers of individuals with ASD (n = 7) and Down syndrome (n = 8). Sociodemographic data, sense of coherence (SOC) (SOC-13 scale), social support (Social Support Scale [MOS-SSS]), oral health-related quality of life (OHRQoL) (OHIP-14), and self-rated oral health assessed on a 5-point Likert scale were collected. A descriptive analysis was performed in addition to correlation analyses (Spearman correlation coefficient). Most primary caregivers were parents of the individual (86.6%). The age of the caregivers ranged between 40 and 59 years (60%). Most caregivers have had 9 to 11 years of education (53.3%). Monthly family income was less than USD 186,28 for ASD caregivers (57.2%) and between USD 327,56 and USD 931,40 for Down syndrome caregivers (50%). Of the caregivers, 33.3% reported good oral health and 33.3% reported neither good nor bad. The average SOC score, social support and OHRQoL was 48.9, 69.3 and 10.9, respectively. The higher the family income, the better the OHRQoL (rs = -0.62, p = 0.014). SOC was correlated with the score of the emotional support domain (rs = 0.54, p = 0.039). It was concluded that caregivers had a strong SOC and high perceived support. Moreover, caregivers did not report a high impact on OHRQoL A better understanding of the caregivers' protective and coping factors in caring for individuals with disabilities may better promote their quality of life.

The role of dental pain and psychosocial factors on the relationship between dental caries and oral health-related quality of life in children.

BACKGROUND: To examine the role of dental pain, sense of coherence (SOC) and social support on the relationship between dental caries and oral health-related quality of life (OHRQoL) in children aged 12 years. METHODS: A cross-sectional study involving 400 schoolchildren selected from public schools in a socioeconomically disadvantaged region in the city of Manaus, Brazil was carried out. The predictors of OHRQoL were selected according to the Wilson and Cleary theoretical model, including number of decayed teeth and its clinical consequence (component D of the DMFT index and PUFA/pufa index), dental pain (symptom status), and SOC and social support (individual and environmental characteristics). Statistical analysis was conducted through structural equation modelling and multivariable negative binomial regression. The significance level established for all analyses was 5%. RESULTS: Number of dental caries was indirectly linked with OHRQoL (ß = 0.19, 95% CI 0.11/0.29) through dental pain, SOC and social support. Clinical consequences of untreated caries directly predicted poor OHRQoL (ß = 0.12, 95% CI 0.01/0.23). Dental pain, SOC and social support did not moderate the effect of dental caries measures on OHRQoL. CONCLUSION: Our findings suggest the role of dental pain, SOC and social support as mediator factors on the link between dental caries and OHRQoL. Tackling dental caries along with psychosocial factors may attenuated the impact of oral health on OHRQoL in children.

The influence of change on sense of coherence on dental services use among adolescents: a two-year prospective follow-up study.

BACKGROUND: To investigate the influence of change on sense of coherence (SOC) on dental services use in adolescents over a two-year period. METHODS: A prospective follow-up study was conducted involving 334 12-year-old adolescents from public schools in the city of Manaus, Amazonas, Brazil. The predictors of use of dental services in the last 12 months were selected according to the Andersen's behavioural theoretical model. The predisposing factors included sex, self-reported skin colour and SOC. The enabling factors were dental insurance, monthly family income and parents/guardians schooling. Dental pain, perceived oral health status, dental caries and gingival status were used to assess need factors. Multivariable Poisson regression with robust variance was used to estimate incidence-rate ratios (IRR) and 95% confidence intervals between the independent variables and use of dental services. RESULTS: Adolescent's SOC scores decreased significantly between baseline and one-year follow-up. SOC decline decreased the likelihood of using dental services in the last 12 months (IRR = 0.96 95%CI 0.92-0.99). Dental caries (IRR = 1.03 95%CI 1.01-1.04) and gingival bleeding (IRR = 1.01 95%CI 1.01-1.02) remained associated with use of dental services in the last 12 months. Adolescents with dental pain were more likely to have visited a dentist in the last year (IRR = 1.03, 95%CI 1.01-1.06). CONCLUSION: SOC decrease over one-year period was a meaningful factor of dental services use among 12-year-old adolescents. Dental pain and clinical conditions were also relevant factors that can influence use of dental services in this group.

Calcium Silicate-Based Sealers Do Not Reduce the Risk and Intensity of Postoperative Pain after Root Canal Treatment when Compared with Epoxy Resin-Based Sealers: A Systematic Review and Meta-Analysis.

This review aims to evaluate whether root canal obturation with calcium silicate-based (CSB) sealers reduces the risk and intensity of endodontic postoperative pain when compared to epoxy resin-based (ERB) sealers. The review was registered at PROSPERO (CRD42020169255). Two independent reviewers conducted an electronic search in PubMed, Scopus, EMBASE, Web of Science, Cochrane Library and LILACS until November 2020 and included only randomized clinical trials with adult health participants undergoing root canal treatment. After selection, the JBI Critical Appraisal tool was used to assess the risk of bias. A fixed-effect meta-analysis was performed to summarize the results of pain risk and pain intensity at time intervals of 24 and 48 hours. Finally, the certainty of evidence was assessed using the GRADE approach. The search resulted in 1,206 records, of which five studies (n = 421 patients) met the eligibility criteria and presented moderate to low risk of bias. There was no significant difference between groups in the risk of pain in the first 24 hours (relative risk or RR = 0.83, 95% confidence interval or CI: 0.60, 1.16, I 2 =) or 48 hours (RR = 0.56, 95% CI: 0.26, 1.21, I 2 =). Silicate-based sealers led to lower pain intensity only at 48 hours (mean and standard deviation = 0.37, 95% CI: 0.69, 0.05). All analyses revealed low heterogeneity (I 2 < 25%). The evidence presented moderate level of certainty. Currently available evidence has shown that there is no difference between CSB and ERB sealers in the risk or intensity of postoperative pain.

The impact on quality of life in patients with burning mouth syndrome: A systematic review and meta-analysis.

OBJECTIVES: The objective of this study was to evaluate the evidence on health-related quality of life (HRQL) and oral health-related quality of life (OHRQL) in patients with burning mouth syndrome (BMS). STUDY DESIGN: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO CRD42020175288). An electronic search was carried out in March 2020 and included clinical trials, cross-sectional studies, and case-control studies. The following databases were screened: Embase, LILACS, PubMed, Web of Science, and Scopus. A gray literature search was performed on Google Scholar and ProQuest Dissertations & Theses Global. The eligibility criteria comprised publications that assessed HRQL or OHRQL in patients with BMS. The risk of bias was evaluated through The Joanna Briggs Institute Critical Appraisal tools. The Grading of Recommendation, Assessment, Development, and Evaluation system was used for the assessment of evidence quality. RESULTS: Thirty-three studies were included, and most presented a low risk of bias. Three meta-analyses were performed based on results of 6 observational studies and showed worse OHRQL (P < .00001) and HRQL (P < .0001) in patients with BMS compared to controls. CONCLUSION: Patients with BMS reported poor HRQL and poor OHRQL compared to control groups, evidencing that this condition affects patients' well-being.

Clinical consequences of untreated dental caries and school performance in low-income adolescents.

BACKGROUND: The possible link between dental status and school performance has been investigated. The influence of the clinical consequences of untreated dental caries in this association, however, has been minimally explored. AIM: To assess the relationship between clinical consequences of untreated dental caries and school performance in adolescents, and to examine the demographics and socioeconomic status pathways by which clinical consequences of untreated dental caries is associated with school performance. DESIGN: A cross-sectional study involving 363 low-income school adolescents was conducted in the city of Manaus, Brazil. Dental clinical measures were registered by five calibrated examiners to evaluate dental caries experience (decayed, missing, and filled teeth index [DMFT]) and clinical sequelae of dental caries (PUFA/pufa index). School performance was assessed using school grade history obtained from official records. Statistical analysis was conducted using pathway analysis to estimate beta coefficients (ß) of the direct and indirect effects between variables. RESULTS: DMFT and PUFA/pufa mean were 1.93 and 0.30, respectively. PUFA/pufa scores (ß = -0.19) and male sex (ß = 0.35) directly predicted poor school performance. DMFT was indirectly linked to poor school performance via PUFA/pufa scores (ß = -0.03). CONCLUSIONS: Dental caries and clinical consequences of dental caries were important predictors of poor school performance in low-income adolescents via direct and indirect effects.

Clinical Consequences of Untreated Dental Caries, Individual Characteristics, and Environmental Factors on Self-Reported Oral Health Measures in Adolescents: A Follow-Up Prevalence Study.

BACKGROUND/AIMS: This study evaluated the relationships of clinical consequences of untreated dental caries, individual characteristics, and environmental factors on self-reported oral health measures in adolescents. METHODS: A follow-up prevalence study was conducted involving 406 twelve-year-old adolescents selected from public schools in the eastern area of the city of Manaus, Brazil. Baseline data included clinical consequences of untreated caries (PUFA/pufa index), DMFT, sociodemographic characteristics (sex, parental schooling, and family income), psychosocial factors (sense of coherence [SOC-13 scale], oral health beliefs and self-esteem [Rosenberg Self-Esteem Scale]), and social support (SSA questionnaire). Oral health-related quality of life (OHRQoL [CPQ11-14]) and self-rated oral health were assessed at the 6-month follow-up. Structural equation modelling was used to explore the relationships between variables according to the Wilson and Cleary model. RESULTS: The prevalence of PUFA/pufa was 17.8% and mean DMFT was 1.5. The number of teeth with clinical consequences of untreated caries predicted poor self-rated oral health at the 6-month follow-up. Low parental schooling predicted low family income and clinical consequences of untreated dental caries. Psychosocial factors predicted OHRQoL directly and self-rated oral health indirectly. OHRQoL was linked to self-rated oral health. Clinical consequences of untreated dental caries mediated the relationship of parental schooling with OHRQoL and self-rated oral health. OHRQoL mediated the relationship of psychosocial factors and sex with self-rated oral health. Clinical consequences of untreated dental caries was associated with adolescents' self-rated oral health. Furthermore, the former was an important mediator on the link between low parental education and adolescents' self-reported oral health measures. CONCLUSIONS: Socioeconomic status, psychosocial factors, and social support were related to OHRQoL and self-rated oral health via direct and indirect pathways.

Socioeconomic status, social support, oral health beliefs, psychosocial factors, health behaviours and health-related quality of life in adolescents.

PURPOSE: This study assessed the relationships between socioecononic status (SES), social support, oral health beliefs, psychosocial factors, health-related behaviours and health-related quality of life (HRQoL) in adolescents. METHODS: A school-based follow-up study involving 376 12-year-old adolescents was conducted in Manaus, Brazil. Baseline data included sociodemographic characteristics (sex, parental schooling, family income, household overcrowding and number of goods), social support (SSA questionnaire), oral health beliefs and psychosocial factors (Sense of Coherence [SOC-13 scale] and self-esteem [Rosenberg Self-Esteem Scale]). Health-related behaviours (toothbrushing frequency, sedentary behaviour, smoking and sugar consumption) and HRQoL [KINDL questionnaire] were assessed at 6-month follow-up. Structural Equation Modelling assessed the relationships between variables. RESULTS: Greater social support (ß = 0.30), higher SOC (ß = 0.23), higher self-esteem (ß = 0.23), higher toothbrushing frequency (ß = 0.14) and less smoking (ß = - 0.14) were directly linked with better HRQoL. SES (ß = 0.05), social support (ß = 0.26), oral health beliefs (ß = - 0.02) were indirectly linked to HRQoL. Higher SES directly predicted higher toothbrushing frequency (ß = 0.14) and less smoking (ß = - 0.22). Greater social support also directly predicted higher SOC (ß = 0.55), positive oral health beliefs (ß = - 0.31) and higher self-esteem (ß = 0.58). Greater social support indirectly predicted less smoking via oral health beliefs (ß = - 0.05) and less sugar consumption via SOC (ß = - 0.07). CONCLUSION: Socioeconomic status, social support, oral health beliefs and psychosocial factors were important predictors of adolescent's health behaviours and HRQoL over 6-month period through direct and indirect mechanisms. Health behaviours also directly influenced HRQoL.

The role of socioeconomic status and psychosocial factors on gingivitis in socially disadvantaged adolescents.

BACKGROUND: Evidence on the possible influence of social and psychosocial factors on gingival status in socially disadvantaged children is scarce. The aim of this study is to assess the relationships among socioeconomic status, pattern of dental visits, self-esteem, oral health beliefs, toothbrushing frequency, oral hygiene effectiveness, and gingivitis in low social status adolescents. METHODS: A cross-sectional study was performed involving 406 12-year-old students recruited in Manaus, Brazil. Socioeconomic status (family income, parent's schooling, number of goods, and household crowding), self-esteem, oral health beliefs, and frequency of toothbrushing were collected through self-completed questionnaires. Gingival status (bleeding on probing) and oral hygiene effectiveness (dental calculus) were evaluated by calibrated dentists through oral examinations. Structural equation modeling assessed the direct and indirect relationships between variables guided by a theoretical model. RESULTS: The prevalence of gingivitis was 77.6%. Worse socioeconomic status and poor oral hygiene effectiveness directly predicted gingival bleeding. Socioeconomic status was also linked to toothbrushing frequency. Positive oral health beliefs and higher self-esteem predicted higher frequency of toothbrushing. The latter was directly linked to greater oral hygiene effectiveness. Oral health beliefs and self-esteem indirectly predicted gingival bleeding via toothbrushing frequency and oral hygiene effectiveness. CONCLUSION: The present findings suggest the importance of socioeconomic status and psychosocial factors on gingival status in underprivileged adolescents. Poor oral hygiene mediated the associations between psychosocial factors and gingival status.

Evaluation of the genotoxic potential of different delivery methods of at-home bleaching gels: a single-blind, randomized clinical trial.

OBJECTIVE: This single-blind, parallel, randomized clinical trial evaluated the genotoxic potential and effectiveness of 10% hydrogen peroxide (HP) in patients submitted to at-home bleaching. MATERIALS AND METHODS: Sixty young volunteers with maxillary incisors equal to or darker than M1.5 were included in the study. Patients were submitted to bleaching for 14 days (30 min/day) with one of the three 10% HP treatments: the bleaching agent was delivered in a bleaching tray (White Class, FGM), whitening strips (White Strips, Oral-b), or in prefilled disposable trays (Opalescence Go, Ultradent). The color change was evaluated with the Vita Bleachedguide, and the micronucleus test of exfoliative oral mucosa was carried out, starting from a count of 1000 cells, at the baseline, immediately after and 30 days after the end of the treatment. The micronucleus data were evaluated with the Kruskal-Wallis and Wilcoxon tests and color change with the two-way ANOVA test and the Tukey test (α = 0.05). RESULTS: Significant whitening was observed for all groups after 14 days (p = 0.001) and was maintained after 30 days, with no difference between groups (p = 0.42). The micronucleus count did not indicate genotoxic potential in any of the groups studied (p = 0.32), irrespective of the time intervals (p = 0.62). CONCLUSION: No genotoxic effects of 10% HP were observed in patients submitted to at-home bleaching systems (30 min/day for 14 days), even 30 days after the end of treatment. CLINICAL SIGNIFICANCE: It is safe to use different systems to deliver 10% HP during at-home bleaching according to the manufacturers' recommendations, with no risk of genotoxic effects applied.

Does oral health influence school performance and school attendance? A systematic review and meta-analysis.

AIM: To examine the evidence on the influence of oral health status on school performance and school attendance in children and adolescents. DESIGN: A systematic review was performed in accordance with PRISMA included epidemiological studies that assessed concomitantly oral health measures, participants' school performance and/or school attendance. Electronic search was conducted on MEDLINE, SCOPUS, Web of Science, ScienceDirect, and LILACS. Studies published up to May 2018 in any language were eligible. The risk of bias was assessed using the Newcastle-Ottawa Scale. Meta-analysis was used to obtain pooled estimates between oral health measures and school performance and school attendance. RESULTS: Eighteen studies were included. Of them, fifteen studies were used for the meta-analyses. Most studies were assessed as moderate quality. Children with one or more decayed teeth had higher probability of poor school performance (OR = 1.44 95%CI: 1.24-1.64) and poor school attendance (OR = 1.57 95%CI: 1.08-2.05) than caries-free children. Poor parent's perception of child's oral health increased the odds of worse school performance (OR = 1.51 95%CI: 1.10-1.92) and poor school attendance (OR = 1.35 95%CI: 1.14-1.57). CONCLUSIONS: Children and adolescents with dental caries and those reporting worse oral health experience poor school performance and poor school attendance.
