RESUMO
PURPOSE: This study described and compared the oral characteristics of Brazilian individuals with mucopolysaccharidosis (MPS) and without MPS. METHODS: A cross-sectional study was performed with 29 individuals with MPS and 29 without MPS and their parents/guardians. The individuals were aged between 3 and 21 years and attended at two hospitals in Belo Horizonte, southeastern Brazil. The dental characteristics were evaluated by clinical examination of dental caries, gingivitis, malocclusion, dental anomalies and developmental defects of enamel. The parents/guardians answered a questionnaire about the sociodemographic and behavioural aspects of their children. The study was approved by the Research Ethics Committee of the Federal University of Minas Gerais. RESULTS: The average age of the individuals was 13.9 years (± 7.2). The majority were male (58.6%), had black/brown skin (70.7%) and were from favored economic class (89.7%). Dental caries, gingivitis, malocclusion and dental anomalies were more prevalent in the MPS group (p < 0.05). CONCLUSION: The individuals with MPS had a higher prevalence of oral diseases and dental anomalies than the group without MPS.

AIM: To measure the impact of dental caries, malocclusion, and traumatic dental injuries (TDI) on the oral health-related quality of life (OHRQoL) of Brazilian children. STUDY DESIGN: population-based cross-sectional study. MATERIALS AND METHODS A representative sample of 1,204 8-to-10-year-old children randomly selected from 19 public and private schools in Belo Horizonte (Brazil) was evaluated. The Decayed, Missing and Filled Teeth Index (DMFT), the Dental Aesthetic Index (DAI), and Andreasen's classification were used by two calibrated examiners to diagnose dental caries, malocclusion, and TDI, respectively. Children were clinically examined at school. The Brazilian version of the Child Perceptions Questionnaire for ages 8 to 10 years (CPQ8-10) was used to assess the impact on OHRQoL. RESULTS: There were statistically significant differences (p<0.001) between groups (dental caries, malocclusion, and TDI) in all subscales and the CPQ8-10 total score. The presence of dental caries alone and its association with TDI and malocclusion were associated with all CPQ8-10 subscales (p<0.05). STATISTICS: the Poisson regression model with a robust variance estimator was utilised for the multivariate analysis. Adjusted prevalence ratios were obtained for the association between oral conditions and the total score on the CPQ8-10 and its subscales. CONCLUSION: Dental caries seems to be the oral condition most commonly associated with a higher impact on the OHRQoL of Brazilian 8-to-10-year-olds.

The aim of this study was to determine the association between verbal school bullying and possible sleep bruxism (SB) in adolescents. A case-control study was carried out at the population level by recruiting 13- to 15-year-old participants among the attendants of schools of Itabira, Brazil. The case group was composed of 103 adolescents with possible SB (i.e. self- or parental-reported), while the control group included 206 adolescents without possible SB. All participants answered a questionnaire on the occurrence of their involvement in verbal school bullying episodes, based on the National School of Health Research (PeNSE) as well as an evaluation of their economic class according to the criteria of the Brazilian Association of Research Companies. Pearson's chi-square, McNemar test and conditional logistic regression were performed to assess the association between possible SB, verbal school bullying and economic class. There were 134 (43·3%) participants who reported involvement in verbal school bullying episodes as a victim, bully or both. The majority of them were males (90·3%). Adolescents with possible SB were more likely to have been involved in episodes of verbal school bullying (OR: 6·20; 95% CI: 3·67-10·48). Based on these findings, it can be suggested that possible SB in young teenagers is associated with a history of episodes of verbal school bullying.

OBJECTIVES: The aims of the present study were to assess caries experience among Brazilian children aged eight to 10 years and determine social factors of this disease, through a multilevel approach. METHODS: This is a cross-sectional study in which a representative sample of 1204 eight-to-ten-year-old children were randomly selected from 19 public and private schools in the city of Belo Horizonte, Brazil. After formal authorization from the parents, the children were clinically examined at school by two calibrated examiners (Kappa=0.78). Individual socioeconomic status was determined using household income, number of residents in the home and parents'/caregivers' schooling. The social vulnerability index and type of school were used as contextual variables. The outcome variables were severity score of dental caries in permanent teeth (DMFT index), dental caries experience in permanent teeth (DMFT = 0 or ≠ 0), severity score of dental caries in primary teeth (dmft index) and dental caries experience in primary teeth (dmft = 0 or ≠ 0). RESULTS: The minority of children (37.2%) had dental caries experience. Chi-squared and Mann-Whitney tests showed that age, parents'/caregivers' schooling, household income and type of school were associated with dental caries experience in permanent and primary teeth (P < 0.05). Mann-Whitney, Kruskal-Wallis tests and Spearman correlation coefficient showed that age, parents'/caregivers' schooling, household income, and type of school were associated with severity score of dental caries in permanent and primary teeth (P < 0.05). In multilevel approach, the individual variables, age and household income demonstrated association with dental caries experience and with severity score of dental caries in primary teeth (P < 0.05). Type of school was also associated with dental caries experience and with severity score of dental caries in these teeth (P < 0.05). In the Poisson multilevel approach, the analysis of the final estimation of variance components of the null model revealed a significant difference among the 19 schools with regard to severity score of dental caries in permanent teeth too (P < 0.001). Younger children and attending private schools showed lower severity score of dental caries in permanent teeth. CONCLUSION: Dental caries experience and severity score of dental caries in primary teeth was influenced by age, household income, and the type of school The dental caries experience in permanent teeth was influenced by age, parents'/caregivers' schooling, household income, and type of school, whereas the severity score of dental caries in permanent teeth was influenced by age and type of school.

PURPOSE: The purpose of this study was to compare mothers' actual observations of signs and symptoms associated with the eruption of primary incisors in their infants with their own recollections of the same period after eruption was completed. METHODS: A comparative study was carried out with 45 non-institutionalized infants and their mothers. Oral clinical exams were performed daily for detection of tooth eruption. The mothers were also interviewed daily about signs and symptoms they thought were associated with teething in the previous 24 hours. One week after the data collection was done, the mothers answered the same questionnaire. Descriptive analysis and the McNemar test (P<.05) were performed. RESULTS: Statistically significant differences were found between the prospective and retrospective studies. Increased salivation (P<.04) and runny nose (P<.001) were reported less often and fever was reported more often (P<.001) in the retrospective evaluation. CONCLUSIONS: Mothers reported similar manifestations of sleep disturbance, diarrhea, loss of appetite, and irritability in the prospective and retrospective studies. Increased salivation and runny nose were more frequently reported in the prospective study, whereas fever was reported 5 times more often in the retrospective study.

AIM: To assess the impact of dental pain on the daily living of 5-year-old preschool children using reports from parents/guardians. DESIGN AND METHODS: A cross-sectional study was carried out involving 549 five-year-old children randomly selected from preschools in the city of Belo Horizonte, Brazil. Data were collected using a previously validated parent-reported questionnaire. The children received dental examinations from a single calibrated examiner. The following outcome variables were selected: age, gender, dental caries, filled teeth, missing teeth, caries involving pulp and social class. Simple and multiple logistic regression analyses were performed on the data. RESULTS: According to parents' reports, 11.1% of children were affected by dental pain in the previous 4 months and of these 72.6% had their daily activities hampered by pain. The majority of these children had difficulty in eating, brushing teeth, sleeping, playing and going to school. The impact of dental pain had a statistically significant association with gender (p=0.001), social class (p=0.009), dental caries (p<0.001), missing teeth (p<0.001), filled teeth (p<0.001) and caries involving pulp (p<0.001). CONCLUSION: The prevalence of difficulties performing tasks of daily living due to dental pain was relatively high among the children studied.

AIM: The purpose of the present study was to assess the prevalence of malocclusion in the primary dentition in a randomised representative sample of Brazilian preschool children. MATERIALS AND METHODS: A cross-sectional survey was carried out in Belo Horizonte, Brazil, involving 1069 male and female preschool children from 60 to 71 months of age, randomly selected from public and private preschools and daycare centers. A questionnaire addressing demographic data was sent to parents/guardians in order to characterise the sample. The oral examination of the children was performed by a single, previously calibrated dentist (kappa inter-examiner agreement value = 0.82). The criterion for the categorisation of malocclusion was at least one of the following conditions: posterior crossbite, overjet (> 2 mm), anterior crossbite, anterior open bite and deep overbite. Univariate analysis was performed using the SPSS software RESULTS: The prevalence of malocclusion was 46.2%. Deep overbite was the most prevalent alteration (19.7% of the sample). Posterior crossbite was diagnosed in 13.1% of the children; 10.5% had accentuated overjet; 7.9% had anterior open bite; and 6.7% had anterior crossbite. CONCLUSION: Malocclusion in primary dentition is becoming a significant problem. The prevalence in the present study was high, especially vertical and transversal malocclusions.

OBJECTIVE: To determine risk indicators for signs and symptoms of temporomandibular disorders (TMD) in children with cerebral palsy (n = 60) and control subjects (n = 60). STUDY DESIGN: The subjects were assessed by means of questionnaire and clinical exam: 1) signs and symptoms of TMD; 2) malocclusions [Dental Aesthetic Index (DAI)]; 3) harmful habits; and 4) bio-psychosocial characteristics. Statistical analysis involved the chi-square, Fisher's exact tests (p < or = 0.05) and multivariate logistic regression (forward stepwise procedure). Variables that achieved a p-value < or = 0.20 were used as potential predictors of signs and symptoms of TMD and applied as co-variables in the multivariate analysis. RESULTS: The prevalence of at least one sign and/or symptom of TMD in the present sample was 1.7% (n = 1) among the individuals in the control group and 13.3% (n = 8) among the individuals with cerebral palsy. The presence of cerebral palsy (Odds Ratio: 9.08; p = 0.041), male gender (OR: 6.21; p = 0.027), severity of the malocclusion (OR: 4.75; p = 0.031), mouth breathing (OR: 5.40; p = 0.022) and mixed dentition (OR: 4.73; p = 0.035) were identified as risk indicators for signs and symptoms of TMD. CONCLUSIONS: It was concluded that children with cerebral palsy had a significantly greater chance of developing signs and symptoms of TMD.

AIM: This was to investigate the prevalence of sleep bruxism in Brazilian schoolchildren. METHODS: A cross-sectional study was carried out examining 652 randomly selected children aged from 7 to 10 years of age from both public and private schools in Belo Horizonte, Brazil. Sleep bruxism among children was reported by parents by means of a pretested questionnaire based on the criteria of the American Academy of Sleep Disorders. The Social Vulnerability Index from Municipal database was used to determine social classification of families. A chi-square test was used with a significance level of 5%. RESULTS: Sleep bruxism was present in 230 children, showing a prevalence of 35.3%. Among the 652 children, 340 (52.0%) were girls and 312 (48.0%) were boys, predominatly of 8-year-olds (84.2%). Sleep bruxism was present in 56.5% of the girls and 43.5% of the boys. The majority of the families were of a low social vulnerability (54.2%), whereas another 45.8% were of a high social vulnerability. More than half of the children without sleep bruxism (55.2%) were of low socio-economic background. CONCLUSIONS: The high prevalence of 35.3% demonstrates the need for further research on this issue.

AIM: The aim of the present study was to assess the prevalence of traumatic dental injury (TDI) in primary teeth and determine predisposing factors. MATERIALS AND METHODS: A cross-sectional study was carried out on 388 male and female Brazilian preschool children between 60 and 71 months of age. A questionnaire addressing demographic data and history of TDI was sent to parents/caregivers. Socioeconomic status was determined using the Social Vulnerability Index (SVI), family income, number of people in the household and parents/caregivers' schooling. The chi-square test was used for the statistical analysis. RESULTS: The prevalence of TDI was 62.1%; 61.7% of the teeth were affected by enamel fracture. Statistically significant associations were found between TDI and increased overjet [OR = 2.24, 95% CI = 1.11- 4.55] and anterior crossbite [OR = 0.38, 95% CI=0.17-0.87]. No statistically significant associations were found between TDI and number of people in the household, family income, social vulnerability, parents/caregivers' schooling, lip competence, overbite, anterior open bite and dental caries (p>0.05). CONCLUSION: The prevalence of TDI was high and enamel fracture was the most common sign of TDI. Children with an increased overjet suffer more TDIs. Socioeconomic factors had no influence over the prevalence of TDI.
