Oral issues and childhood stress in eight-to-ten-year-old schoolchildren: a case-control study.

OBJECTIVE: The aim of the present study was to investigate whether oral problems, harmful oral habits, and sociodemographic factors are associated with the occurrence of stress in schoolchildren. MATERIALS AND METHODS: A case-control study nested within a cross-sectional study was conducted with a sample of 375 schoolchildren eight to ten years of age in the city of Diamantina, Brazil. The case group (with childhood stress) and control group (without childhood stress) were matched for age and sex at a 1:4 ratio (75 cases to 300 controls). Data collection involved the self-administration of a questionnaire by parents/caregivers addressing sociodemographic characteristics and the child's history of harmful oral habits. The children answered the Child Stress Scale (CSS) and underwent a clinical oral examination to determine the presence/absence of dental caries, malocclusion, and traumatic dental injuries. Data analysis involved the calculation of frequencies, the chi-square test, and conditional logistic regression (95% CI; p ≤ 0.05). RESULTS: The final adjusted conditional logistic regression model showed that dental caries (OR = 1.78, 95% CI: 1.01 - 3.14, p = 0.044) and biting objects (OR = 1.81, 95% CI: 1.02 - 3.22, p = 0.041) remained associated with stress in the schoolchildren analysed. CONCLUSION: The present results showed that children with dental caries and the habit of biting objects were more likely to have childhood stress. CLINICAL RELEVANCE: The study allows paediatric dentists to expand their knowledge with regards to the influence of oral problems and harmful habits on the occurrence of childhood stress and serves as a guide for decision-making related to oral problems in schoolchildren.

Oral health issues in children and adolescents with vision impairment: A systematic review and meta-analysis.

BACKGROUND: Children and adolescents with vision impairment (VI) may be at increased risk of oral health issues, such as periodontal inflammation, poor oral hygiene, dental caries, and dental trauma, but this is inconclusive in the literature. AIM: To systematically review the literature to determine the main oral health issues of children and adolescents with VI compared to those without VI. DESIGN: Electronic and manual searches were performed to identify observational studies involving children and adolescents with and without VI, to determine and compare their oral health issues. The methodological quality was assessed using the Joanna Briggs Institute critical appraisal tool. Studies that had homogeneity of methods were incorporated into meta-analyses. RESULTS: Fifteen cross-sectional studies were included. Overall, most studies presented methodological flaws and high risk of bias. The meta-analysis showed that children and adolescents with VI were 3.86 times as likely to exhibit dental trauma (OR = 3.86, 95% CI = 2.63-5.68, I2  = 0%) and had higher/poorer values for plaque (MD = 0.80, 95% CI = 0.58-1.02, I2  = 96%), gingivitis (MD = 0.69, 95% CI = 0.02-1.37, I2  = 100%), calculus (MD = 0.04, 95% CI = 0.03-0.06, I2  = 0%), and oral hygiene indices (MD = 0.71, 95% CI = 0.24-1.18, I2  = 97%), as well as DMFS (MD = 0.90, 95% CI = 0.68-1.13, I2  = 26%). CONCLUSION: Across a wide array of assessments, children and adolescents with vision impairment had worse oral health outcomes than those without VI.

Do family functioning and mothers' and children's stress increase the odds of probable sleep bruxism among schoolchildren? A case control study.

OBJECTIVE: To investigate the association between probable sleep bruxism (PSB) and associated factors in schoolchildren. MATERIALS AND METHODS: A case-control study was conducted with a representative sample of 320 schoolchildren aged 8 to 10 years. The case group (160 children with PSB) and the control group (160 children without PSB) were matched for sex and age at a proportion of 1:1. Information on audible characteristics of PSB, harmful oral habits, and socio-demographic characteristics as collected through questionnaires answered by the parents/caregivers. The family functioning of children was measured through The Family Adaptability and Cohesion Evaluation Scales (FACES III). Mothers self-administered the Lipp Stress Symptoms Inventory (LSSI) for adults to measure mothers' stress and the children filled out the Child Stress Scale (CSS) to measure the children stress. Data analysis used descriptive and logistic regression analyses (p < 0.05). RESULTS: Among the children with stress, 67.3% had PSB. Children with stress (OR = 2.22, 95% CI 1.18-4.19), those with a history of nail biting (OR = 2.22, 95% CI 1.39-3.55), and biting objects (OR = 1.77, 95% CI 1.09-2.87) were more likely to have PSB. CONCLUSION: Childhood stress and a history of nail biting or biting objects are important signs to be considered in schoolchildren with PBS. CLINICAL RELEVANCE: These results alert that the PBS might be a sign of stress and other psychological problems such as tension and anxiety related to the presence of harmful oral habits. Furthermore, the results could help in the targeting of anamnesis, improved prevention and treatment strategies for sleep bruxism which should involve an interdisciplinary approach.

Do Patients with Extrinsic Black Tooth Stains Have a Lower Dental Caries Experience? A Systematic Review and Meta-Analysis.

Studies have suggested that individuals affected by extrinsic black tooth stains have less dental caries experience in comparison to those without this condition. The aim of the present study was to perform a systematic review and meta-analysis to determine whether there is scientific evidence demonstrating that extrinsic black stains are a protective factor for the occurrence of dental caries. This systematic review was developed in accordance with the PRISMA statement and the research question was determined using the PECO strategy. Electronic searches were conducted in the PubMed, Science Direct, Virtual Health Library, Cochrane, Web of Science, and Google Scholar databases for relevant articles published up to September 2018. All articles included were submitted to an appraisal of methodological quality using the Newcastle-Ottawa Scale and the data were extracted for meta-analysis. The search strategy resulted in the retrieval of 9,108 publications. After the application of the eligibility criteria, 18 articles were selected for analysis, 13 of which were included in the meta-analysis. The meta-analysis demonstrated that individuals with extrinsic black stains involving primary (median, MD: -0.78 [-1.09; -0.48]; I2 = 44%) and permanent (MD: -0.50 [-0.93; -0.08]; I2 = 86%) teeth have a lower dental caries experience in comparison to those without this condition. Patients with extrinsic black tooth stains have a lower dental caries experience in cross-sectional studies.

Prevalence of probable sleep bruxism and associated factors in Brazilian schoolchildren.

AIM: To determine the prevalence of probable sleep bruxism (PSB) and associated factors among schoolchildren. DESIGN: This cross-sectional study was carried out with a representative sample of 440 schoolchildren. The children were submitted to a clinical oral examination for the evaluation of tooth wear and/or muscle discomfort. Parents/caregivers filled out a questionnaire with information related to characteristic sounds of sleep bruxism, sociodemographic factors, and the presence of harmful oral habits of children. The stress of the mothers was measured through the Lipp's Stress Symptoms Inventory for Adults (LSSI) instrument. The child's stress was measured through the Child Stress Scale (CSS). Data analysis included descriptive analysis and hierarchical Poisson regression (95% CI, P < 0.05). RESULTS: The prevalence of PSB was 40.0% (n = 176). The final Poisson regression model showed that PSB was significantly more prevalent in children with a history of nail biting (PR: 1.50; 95% CI: 1.19-1.90; P = 0.001) and biting objects (PR: 1.30; 95% CI: 1.03-1.63; P = 0.025) and less prevalent among girls (PR: 0.78; 95% CI: 0.63-0.98; P = 0.033). CONCLUSIONS: The prevalence of PSB in schoolchildren was high. Schoolchildren with a history of nail biting and biting objects had a higher prevalence of PSB.

Dental caries, but not malocclusion or developmental defects, negatively impacts preschoolers' quality of life.

BACKGROUND: Oral diseases can negatively influence the quality of life causing harm in the development of routine activities, child development and their well-being. AIM: To investigate the impact of dental caries, malocclusion and developmental defects of enamel (DDE) on the oral health-related quality of life of preschool children and their parents. DESIGN: A cross-sectional study was carried out with 646 children aged 2-6 years in Diamantina, Brazil. Calibrated dental examiners performed the oral examinations. Parents answered the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and a questionnaire on socio-economic indicators. Statistical analyses involved the chi-square test and Poisson regression. RESULTS: Malocclusion and DDE did not cause a negative impact on the children's quality of life. Children with dental caries (PR: 1.92; 95%CI: 1.56-2.35) and those aged 5 (PR: 1.51; 95%CI: 1.13-2.02) and 6 years (PR: 1.51; 95%CI: 1.02-2.23) were more likely to have a negative quality of life impact on the total B-ECOHIS. CONCLUSIONS: Dental caries was associated with a negative impact on the quality of life of children. Malocclusion and DDE did not cause a negative impact on the children's quality of life. Older children had higher frequency of negative impact on OHRQoL.

Impact of traumatic dental injury on the quality of life of young children: a case-control study.

There are no longitudinal studies that assess the impact of traumatic dental injury (TDI) on the oral health-related quality of life (OHRQoL) of preschool children. To investigate the impact of TDI on OHRQoL among preschool children, a population-based case-control study was carried out with a representative sample of 335 children, 3-5 years of age, enrolled at public and private preschools in the city of Campina Grande, Brazil. The case group and the control group were matched for age, gender, type of preschool and monthly household income at a ratio of 1:4 (67 cases and 286 controls). Impact on the OHRQoL of children was assessed through administration of the Early Childhood Oral Health Impact Scale (ECOHIS). The occurrence of TDI was determined through clinical examinations performed by three calibrated dentists. Data analysis involved descriptive statistics, McNemar's test, the chi-square test with linear trend and conditional logistic regression analysis [P≤0.05; 95% confidence interval (95% CI)]. The most frequent responses were 'felt pain' (19.4%) and 'difficulty eating' (16.4%). The prevalence of TDI was 37.3% in the case group and 33.9% in the control group. No statistically significant differences were found between case and control groups regarding the presence of TDI (odds ratio=1.16; 95% CI: 0.66-2.02). TDI had no impact on the quality of life of preschool children.

Impact of oral mucosal conditions on oral health-related quality of life in preschool children: a hierarchical approach.

OBJECTIVE: To determine the impact of oral mucosal conditions on OHRQoL in preschool children. METHODS: A cross-sectional study was carried out with a selected representative sample of 724 children aged 2-5 years and their parents/caregivers. Data were collected through interviews with parents/caregivers, who also answered the B-ECOHIS. A clinical oral examination was performed to determine oral mucosal conditions, dental caries, dental trauma, and malocclusion. Data analysis involved descriptive statistics, the Kolmogorov-Smirnov normality test, the Mann-Whitney U-test and hierarchically adjusted Poisson regression models (P < 0.05, 95% CI). RESULTS: The prevalence of oral mucosal conditions was 50.7%, the most prevalent of which were melanotic macules (17.8%), oral ulcers (11.0%), Fordyce's spots (9.4%), geographic tongue (5.2%), fissured tongue (1.9%), median rhomboid glossitis (1.8%), and fistula (1.4%). In the final multivariate model, child with 5 years of age (RR = 1.60; 95% CI: 1.08-2.38; P = 0.020), with presence of fistula (RR = 1.94; 95% CI: 1.27-2.95; P = 0.002), and with dental caries (RR = 2.58; 95% CI: 2.00-3.35; P < 0.001) had a negative impact on children's OHRQoL. CONCLUSION: Child with 5 years of age, presence of fistula, and dental caries were associated with a negative impact on the quality of life of preschool children.

Oral mucosal conditions in preschool children of low socioeconomic status: prevalence and determinant factors.

The aim of the present study was to determine the prevalence of oral mucosal conditions and associated factors among 541 preschoolers of low socioeconomic status. A cross-sectional study was carried out. Sociodemographic data and information on harmful oral habits were gathered with the use of a questionnaire. A clinical exam was performed for the determination of oral mucosal conditions, dental caries and level of oral hygiene. Data analysis involved statistical analysis, the Kruskal-Wallis test, Mann-Whitney test, chi-square test, Fisher's exact test and multivariate regression (p < 0.05, 95 % CI). The prevalence of oral mucosal conditions was 40.7 %. The most prevalent oral mucosal conditions were coated tongue (23.4 %), melanotic macules (14.4 %), oral ulcers (11.8 %), Fordyce's spots (8.1 %), angular cheilitis (3.0 %), geographic tongue (2.8 %), linea alba (1.5 %) and fistula (1.3 %). Children between 3 and 5 years of age had a greater chance of exhibiting coated tongue (OR, 2.55; 95 % CI, 1.6-4.1), melanotic macules (OR, 4.07; 95 % CI, 2.3-7.2) and Fordyce's spots (OR, 12.70; 95 % CI, 7.2-28.6). The female gender had a greater chance of exhibiting melanotic macules (OR, 2.23; 95 % CI, 1.3-1.8). Coated tongue was more prevalent among children from low-income families (OR, 2.35; 95 % CI, 1.3-4.3) and those with inadequate oral hygiene (OR, 4.65; 95 % CI, 2.9-7.4). Caries constituted a predictive factor for oral ulcers (OR, 2.15; 95 % CI, 1.2-3.9) and fistula (OR, 12.00; 95 % CI, 1.4-11.3). Bruxism (teeth clenching/grinding) was a predictive factor for angular cheilitis (OR, 5.55; 95 % CI, 1.9-16.3). The determinant factors for oral mucosal conditions were the female gender, age between 3 and 5 years, inadequate oral hygiene, low household income, residence in rural areas and presence of dental caries and bruxism.

Esthetic recovery of smile using composite resin and "biological posts" and crowns.

The recovery of teeth that have been extensively destroyed by dental caries can be achieved through direct and indirect restorative procedures. This paper presents a case of the esthetic and functional recovery of permanent maxillary incisors with extensive dental caries in an adolescent patient through the use of a composite resin and "biological posts and crowns". A case report was drafted to describe the direct restoration of central maxillary incisors using composite resin and endodontic treatment of the lateral maxillary incisors, the construction of dentinal posts, the adaptation and cementing of the posts to the root canals, preparation and molding of crown portions, model construction, the choice of extracted teeth and the making and cementing of "biological crowns". The use of a composite resin and the cementing of "biological posts and crowns" reestablish dental esthetics and function. Biological restorations maintain all the characteristics of natural teeth and have a significant psychosocial impact on the patient's quality of life. However it should be stressed that this technique was only indicated in the present case after the determination of a significant improvement in oral hygiene.

Longitudinal evaluation of determinants of the clinical consequences of untreated dental caries in early childhood.

OBJECTIVES: This study aimed to evaluate whether the trajectory of family income, parental education and clinical variables are associated with the clinical consequences of untreated dental caries among children. METHODS: A prospective cohort study was conducted with 439 children between one and three years of age, evaluated at baseline and re-evaluated after three years. Sociodemographic and economic variables, untreated dental caries and biofilm were investigated both at baseline and at the 3-year follow-up. The pufa index (pulpal involvement, ulceration, fistula and abscess) was used to diagnose the clinical consequences of untreated dental caries. RESULTS: The prevalence of pufa ≥1 was 18.2% in the follow-up. The following variables were associated with a higher risk of clinical consequences of untreated dental caries: mother's low schooling level at baseline and follow-up (RR = 1.51; 95% CI: 1.04-2.18), incidence or baseline presence of biofilm (RR = 4.66; 95% CI: 2.02-10.74), cavitated dental caries at baseline (RR = 3.57; 95% CI:1.86 to 6.83) and incidence of cavitated dental caries (RR = 2.04; 95% CI: 1.24-3.35). CONCLUSION: Low maternal schooling level, biofilm, cavitated dental caries at baseline, and incidence of dental caries were the factors determining the consequences of untreated dental caries.

Risk indicators of untreated dental caries incidence among preschoolers: a prospective longitudinal study.

The aim of the present study was to evaluate the influence of socioeconomic factors, oral conditions and the impact of OHRQoL as possible risk indicators related to the incidence of untreated dental caries in preschool children two years after an initial examination. A prospective longitudinal study was performed with a sample of 288 preschool children allocated to two groups at baseline (T0): caries free (n = 144) and with untreated dental caries (n = 144). Untreated dental caries was determined through clinical examinations performed by a calibrated dentist at T0 (Kappa > 0,89) and T1 (two years after the baseline) (Kappa > 0,91) using the dmft criteria. Parents/caregivers answered a socioeconomic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) at T0 and T1. Mann-Whitney test and hierarchically adjusted Poisson regression models were used (95%CI, p < 0,05). The incidence of untreated dental caries was 41.3%. Low (RR = 1.63; 95%CI:1.18-2.26; p < 0.001) and high severity of untreated dental caries (RR = 1.92; 95%CI:1.36-2.72; p < 0.001), monthly household income less than two times the Brazilian minimum salary (RR = 1.79; 95%CI:1.04-3.25; p = 0.042) and overall B-ECOHIS score (RR = 1.03; 95%CI:1.02-1.05; p < 0.001) at T0 were risk indicators for the incidence of untreated dental caries among the preschool children. In conclusion, the incidence of untreated dental caries was high and the higher severity of untreated dental caries, the lower monthly income and the higher the B-ECOHIS score (indicating a negative impact on quality of life) were risk indicators to the developing of new lesions of untreated dental caries after 2 years.

Does religiosity impact binge drinking among early adolescents? A cross-sectional study in a city in Southeastern Brazil.

This study evaluated the association between religiosity and binge drinking in early adolescence. A cross-sectional study was conducted with adolescents aged 10-13 from Belo Horizonte, Brazil. Stratified random sampling was performed considering the administrative district and school year. Adolescents filled an AUDIT-C form, containing questions about religiosity and binge drinking by parents and their best friends. Adolescents' caregivers answered a form regarding socioeconomic issues. Descriptive analysis, univariate, and multivariate logistic regression were performed. A total of 650 adolescents participated in the study. The frequency of binge drinking was 13.7%. In the adjusted model, religiosity was not associated with binge drinking. The covariates associated were the age of 12-13 years (OR: 1.94; CI95%: 1.06-3.56; p=0.030), maternal binge drinking (OR: 3.12; CI95%: 1.76-5.52; p<0.001) best friend binge drinking (OR: 6.01; CI95%: 3.40-10.62; p<0.001) and nonnuclear family (OR: 1.80; CI95%: 1.01-3.23; p=0.045). The findings revealed that, for binge drinking, the main factors that influenced this decision were the best friend and maternal binge drinking and family structure, although the adolescents claimed to be religious.

Prevalence of oral health-related shame and associated factors among Brazilian schoolchildren.

The aim of the present study was to investigate the prevalence of oral health-related shame and the associated factors among 8-to-10-year-old Brazilian schoolchildren. A cross-sectional study was conducted with 388 children randomly selected from public and private schools of Diamantina, southeastern Brazil. In order to identify the feeling of shame, self-reports were collected through a single question, "In the last month, did you feel ashamed because of your teeth or mouth? Two calibrated examiners performed the clinical examination for dental caries (DMFT/dmft index), traumatic dental injuries (O' Brien), and malocclusion (Dental Aesthetic Index). Sociodemographic indicators were obtained through a questionnaire answered by the children's caregivers. Descriptive analysis, chi-square test, and hierarchical Poisson regression models were performed (95%CI; p < 0.05). The prevalence of shame was 38.1% (n = 148). The adjusted regression analysis demonstrated a significant association between shame and untreated dental caries (PR: 1.34; 95%CI: 1.04-1.74; p = 0.02), age of 10 years (PR: 1.36; 95%CI: 1.05-1.76; p = 0.01), and with parents with less than eight years of schooling (PR: 1.30; 95%CI: 1.00-1.68; p = 0.04). Older children with untreated dental caries and whose parents had lower education level presented a higher prevalence of oral health-related shame.

Determinant factors for immediate care seeking after traumatic dental injury among Brazilian children.

The present study aimed to evaluate the frequency of immediate care seeking after traumatic dental injury (TDI) in primary dentition and its association with the children's characteristics, socioeconomic status, and TDI characteristics. This was a cross-sectional study with dental records of children aged 9 months to 6 years who attended a reference center in TDI in primary dentition between 2007 and 2018. Immediate care seeking after TDI, child's characteristics, sociodemographic conditions and TDI characteristics were collected. Descriptive statistics and Poisson regression analysis with robust variance were performed (p < 0.05; 95%CI). Among the 493 dental records, 61.1% (n = 301) were of males and 50.5% (n = 249) were from children aged 2 years or less. More than one third of the sample (36.9%; n = 182) sought immediate care after TDI. Among the types of TDI, the prevalence of soft tissue injuries was 59.0% (n = 291), while 51.7% (n = 255) were hard tissue injuries and 54.0% (n = 266) were supporting tissue injuries. Immediate care seeking after TDI was higher in children who needed suture (PR: 1.39; 95%CI: 1.01-1.92. p = 0.039), had luxation (lateral, intrusion, or extrusion) (PR: 2.36; 95%CI: 1.36-4.08. p = 0.002) or avulsion (PR: 2.18; 95%CI: 1.28-3.70. p = 0.004). The need for suture, luxation (lateral, intrusion and extrusion), and avulsion were determinant factors for the immediate care seeking after TDI, regardless of the child's characteristics and socioeconomic status.

Fluoride content in children's dentifrices marketed in Lima, Peru.

The aim of the present study was to determine the concentration of total fluoride (TF) and total soluble fluoride (TSF) in children's dentifrices marketed in the city of Lima, Peru. Three samples of 23 dentifrices (4 without fluoride and 19 with fluoride) were purchased in different pharmacies in Lima, Peru. The TF and TSF concentrations found in the dentifrices were determined by ion-selective electrode, expressed in ppm F (µg F/g of dentifrice). The TF concentration in the majority of the fluoride toothpastes matched that shown on the label, except for one declared as 1450 ppm F by the manufacturer, whereas only 515.1 ppm F was found. The concentration of TSF found in the fluoride toothpastes ranged from 457.5 to 1134.8 ppm F. All the dentifrices were formulated with silica, but one also presented calcium carbonate. In conclusion, 83% of the children's dentifrices marketed in Lima, Peru, were fluoridated, but only 53% contained a TSF concentration greater than 1000 ppm F, the minimum concentration required to provide an anticaries effect.

Risk indicators of untreated dental caries incidence among preschoolers: a prospective longitudinal study

Abstract: The aim of the present study was to evaluate the influence of socioeconomic factors, oral conditions and the impact of OHRQoL as possible risk indicators related to the incidence of untreated dental caries in preschool children two years after an initial examination. A prospective longitudinal study was performed with a sample of 288 preschool children allocated to two groups at baseline (T0): caries free (n = 144) and with untreated dental caries (n = 144). Untreated dental caries was determined through clinical examinations performed by a calibrated dentist at T0 (Kappa > 0,89) and T1 (two years after the baseline) (Kappa > 0,91) using the dmft criteria. Parents/caregivers answered a socioeconomic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) at T0 and T1. Mann-Whitney test and hierarchically adjusted Poisson regression models were used (95%CI, p < 0,05). The incidence of untreated dental caries was 41.3%. Low (RR = 1.63; 95%CI:1.18-2.26; p < 0.001) and high severity of untreated dental caries (RR = 1.92; 95%CI:1.36-2.72; p < 0.001), monthly household income less than two times the Brazilian minimum salary (RR = 1.79; 95%CI:1.04-3.25; p = 0.042) and overall B-ECOHIS score (RR = 1.03; 95%CI:1.02-1.05; p < 0.001) at T0 were risk indicators for the incidence of untreated dental caries among the preschool children. In conclusion, the incidence of untreated dental caries was high and the higher severity of untreated dental caries, the lower monthly income and the higher the B-ECOHIS score (indicating a negative impact on quality of life) were risk indicators to the developing of new lesions of untreated dental caries after 2 years.

Resumo O objetivo do estudo foi avaliar a associação entre religiosidade e binge drinking no início da adolescência. Um estudo transversal realizado com adolescentes de 10 a 13 anos de Belo Horizonte, Brasil. Foi realizada uma amostragem aleatória estratificada considerando distrito administrativo e ano escolar. Os adolescentes preencheram um formulário com o AUDIT C, perguntas sobre religiosidade e perguntas sobre binge drinking pelos pais e melhor amigo. Um formulário sobre questões socioeconômicas foi respondido pelos responsáveis. Foi realizada análise descritiva, regressão logística univariada e multivariada. Participaram do estudo 650 adolescentes. A frequência de binge drinking foi de 13,7%. No modelo ajustado, a religiosidade não esteve associada ao binge drinking. As covariáveis associadas foram idade de 12-13 anos (OR: 1,94 IC95%: 1,06-3,56; p=0,030), binge drinking pela mãe (OR: 3,12; IC95%: 1,76-5,52; p<0,001) binge drinking pelo melhor amigo (OR: 6,01; IC95%: 3,40-10,62; p<0,001) e família não nuclear (OR: 1,80; IC95%: 1,01-3,23; p=0,045). Os achados revelaram que apesar dos adolescentes afirmarem serem religiosos, para o binge drinking, os principais fatores que influenciaram essa decisão foi o binge drinking pelo melhor amigo, mãe e família não nuclear.

Case-control study examining the impact of oral health problems on the quality of life of the families of preschoolers.

The aim of this study was to evaluate the impact of dental caries, traumatic dental injuries (TDI), toothaches, and malocclusion on the oral health-related quality of life (OHRQoL) of the families of Brazilian preschool children. A population-based, matched case-control study involving 415 pre-schoolers aged 3-5 years was conducted. The case (impact on OHRQoL) and control groups (no impact on OHRQoL) were matched for age, gender, and family income at an 1:4 ratio. Impact on the OHRQoL of a family was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI, and malocclusion were diagnosed by three calibrated dentists (Kappa: 0.85-0.90). Data analysis involved descriptive statistics and conditional logistic regression analysis (p ≤ 0.05; 95%CI). There were no differences between the cases and controls regarding age, gender, and family income (p > 0.05). The most frequent responses on the B-ECOHIS among cases were "felt guilty" (68.6%) and "been upset" (48.2%). The following variables were significantly associated with negative impacts on family OHRQoL (cases): caries severity (OR = 6.680; 95%CI = 2.731-16.349), a history of toothache (OR = 2.666; 95%CI = 1.492-4.765), parental rating of the child's oral health as poor (OR: 1.973; 95%CI = 1.072-3.634), and parent's/caregiver's age (OR = 2.936; 95%CI = 1.077-3.478). Anterior open bite was positively associated with OHRQoL (OR = 4.050; 95%CI = 1.333-12.314). Caries severity, a history of toothache, parental rating of the child's oral health as poor, and younger parents/caregivers were associated with impact on the OHRQoL of the families of preschoolers.

Association between oronasopharyngeal abnormalities and malocclusion in Northeastern Brazilian preschoolers.

OBJECTIVE: Evidence is contradictory regarding the association between oronasopharyngeal abnormalities and malocclusion. The aim of the present study was to assess the association between oronasopharyngeal abnormalities and malocclusion (anterior open bite and posterior crossbite) in preschoolers. METHODS: A cross-sectional study was conducted with a representative sample of 732 preschoolers aged 3-5 years old selected randomly from private and public preschools. Anterior open bite (AOB) and posterior crossbite (PC) were evaluated through a clinical exam. Parents/caregivers answered a questionnaire addressing sociodemographic indicators and oronasopharyngeal issues. Statistical analysis involved descriptive analysis and Poisson regression (p < 0.05). RESULTS: The prevalences of AOB and PC were 21.0% and 11.6%, respectively. Being three years old (PR = 1.244; 95% CI = 1.110-1.394; p < 0.001), being four years old (PR = 1.144; 95% CI = 1.110 - 1.394; p = 0.015), absence of allergy (PR = 1.158; 95% CI = 1.057 - 1.269; p = 0.002), not having undergone nose surgery (PR = 1.152; 95% CI = 1.041 - 1.275; p = 0.006) and having a sore throat more than five times in the same year (PR = 1.118; 95% CI = 1.011 - 1.237; p = 0.030) were significantly associated with AOB. The absence of asthma (PR = 1.082; 95% CI = 1.012 - 1.156; p = 0.020), not having undergone throat surgery (PR = 1.112; 95% CI = 1.068 - 1.158; p < 0.001) and not having undergone nose surgery (PR = 1.114; 95% CI = 1.069 - 1.160; p < 0.001) remained associated with PC. CONCLUSION: Significant associations were found between oronasopharyngeal-reported abnormalities and the presence of AOB and PC in preschoolers.
