Rare dental developmental disturbance in primary and permanent teeth following trauma prior to tooth eruption: Case report.

Traumatic dental injuries are highly prevalent among preschool children. When occurring at a very young age (prior to the eruption of the primary teeth), such trauma can disturb the normal development of the permanent dentition and, more rarely, affect the primary dentition. This report describes a case of a patient who suffered dentoalveolar trauma at six months of age that caused rare developmental problems in the primary dentition, such as impaction, dilacerations, hypoplasia, and odontoma. Imaging revealed that alterations also occurred in the permanent dentition. This report demonstrates that dentoalveolar trauma prior to complete development of the dentition and even before the eruption of the primary teeth can lead to highly uncommon abnormalities in the primary dentition. Moreover, there may be repercussions in the permanent dentition when the germs of these teeth are injured by the intraosseous displacement of primary teeth.

The association of childhood sleep problems with the prevalence of traumatic dental injury in schoolchildren.

BACKGROUND/AIM: Sleep quality exerts an influence on attention level and motor skills and is associated with accidental injuries in children. The aim of this study was to evaluate the association between traumatic dental injury and sleep behaviour in children. MATERIAL AND METHODS: A cross-sectional study was conducted in a small city in southern Brazil with a representative sample of schoolchildren aged 8-10 years (n = 537). Weight and height were measured, and examinations were performed for the determination of clinical occlusion and traumatic dental injury. The parents answered the Sleep Behaviour Questionnaire and questions addressing socio-demographic characteristics. RESULTS: The prevalence of traumatic dental injury was 22% (95% CI: 19-26) and was higher among children who woke three to four times per night (PR = 3.30; 95% CI: 2.47-4.39), those who fell asleep in the parental bed (PR = 1.41; 95% CI: 1.09-1.83), those who were not in a good mood on waking up in the morning (PR = 1.30; 95% CI: 1.02-1.65), those who became sleepy while sitting and/or studying (PR = 1.57; 95% CI: 1.09-2.24) and while watching TV (PR = 1.41; 95% CI: 1.0005-1.97) and those who had bad dreams (PR = 1.35; 95% CI: 1.04-1.76). The Poisson multiple regression model with a multilevel approach revealed that the prevalence of traumatic dental injury was 1.51-fold higher among children with daytime drowsiness (PR = 1.51; 95% CI: 1.11-2.04) after adjusting for socio-demographic, occlusal and anthropometric variables. CONCLUSION: Sleep problems were associated with a higher prevalence of traumatic dental injury among the children analysed.

Reliability of self-reported toothbrushing frequency as an indicator for the assessment of oral hygiene in epidemiological research on caries in adolescents: a cross-sectional study.

BACKGROUND: In the present state of knowledge regarding the etiology of dental caries, it is unacceptable for studies addressing factors associated with this outcome to disregard oral hygiene. Simple, valid methods are needed for the assessment of oral hygiene in adolescents to allow this condition to be properly investigated in epidemiological studies on caries and assist in the establishment of health promotion measures. The aim of the present study was to test the hypothesis that the self-reported toothbrushing frequency can be used as a proxy measure for clinical oral hygiene indices in epidemiological studies on dental caries in adolescents. METHODS: A cross-sectional study was conducted with a representative sample (n = 589) of 12-year-old school children in a medium-sized city in southern Brazil. A detailed questionnaire addressing socio-demographic and economic characteristics was sent to primary caregivers. Adolescents answered a brief self-administered questionnaire on behavioral characteristics, including toothbrushing frequency and sugar intake. Samples of stimulated saliva were collected from the adolescents and evaluated for levels of mutans streptococci and lactobacilli using Dentacult kits I and II, respectively. Examiners who had undergone a training and calibration exercise (kappa > 0.81) performed the clinical examination of the adolescents. Caries experience was assessed using the decayed, missing and filled teeth index. Oral hygiene was determined using the Simplified Oral Hygiene Index and the Visible Plaque Index. RESULTS: When the oral hygiene variables were used alone in the multiple models, significant associations with dental caries were found. When Simplified Oral Hygiene Index and/or Plaque Index were used together with toothbrushing frequency in the same model, only the latter was significantly associated with dental caries. A significant association was also found between self-reported toothbrushing frequency and the clinical indices. CONCLUSION: Based on the present findings, self-reported toothbrushing frequency can be used as a proxy measure for clinical oral hygiene indices, which facilitates data collection in epidemiological studies addressing dental caries in adolescents.

Oral health-related quality of life among Brazilian dental students.

This study was conducted to assess oral health-related quality of life (OHRQoL) among Brazilian dental students. A cross-sectional study was carried out involving 300 dental students at the Federal University of Parana, Brazil. To measure OHRQoL, the Oral Health Impact Profile (OHIP-14) was self-administered and a questionnaire was filled out addressing socio-demographic characteristics, health-related aspects and dental experience. Descriptive analysis was performed and both univariate and multivariate Poisson regression with robust variance were used to determine associations between OHRQoL and the covariables. The prevalence of reported impact on OHRQoL was 45 percent. The mean OHIP-14 score was 4.5. In the univariate analysis, the reason for the last visit to the dentist (p = 0.004), reported discomfort in teeth/mouth (p < 0.001) and both self-rated general (p = 0.011) and oral (p < 0.001) health were significantly associated with OHRQoL. The year of academic education was not associated with OHRQoL (p = 0.712). In the multivariate model, students who reported dissatisfaction with their teeth (PR = 1.32; IC 95%: 1.01-1.73), dental pain/sensitivity (PR = 2.36; IC 95%: 1.63-3.40), esthetic dental problems (PR = 1.45; IC 95%: 1.10-1.89), restorative needs (PR = 1.60; IC 95%: 1.01-2.55) and whose last visit to the dentist was for curative treatment (PR = 1.36; IC 95%: 1.05-1.76) had greater impact on OHRQoL. Aspects related to previous dental experience and self-reported oral health problems were associated with OHRQoL.

Family Cohesion Is Associated with the Self-Perceived Need for Dental Treatment among Adolescents.

This study explored the association between family cohesion and self-perceived need for dental treatment among adolescents. A school-based representative cross-sectional study was conducted with 746 students aged 15 to 19 randomly selected from schools in Campina Grande, Brazil. Parents/guardians provided information on sociodemographic data, and students completed questionnaires about the self-perceived need for dental treatment, dental pain, and family cohesion and adaptability (FACES III). Two dentists were trained (kappa >0.80) to diagnosis dental caries using the Nyvad criteria and assess adolescents' level of functional oral health literacy (BREALD-30). Descriptive analysis was performed, followed by nonadjusted and adjusted robust binary logistic regression for complex samples (α = 5%). The prevalence of self-perceived need for dental treatment was 88.6%. The presence of dental caries (OR = 2.10; IC 95%: 1.22-3.61), tooth loss (OR = 15.81; IC 95%: 2.14-116.56), dental pain in the last six months (OR = 1.87; IC 95%: 1.06-3.31), and enmeshed family cohesion type (OR = 10.23; IC 95%: 3.96-26.4) remained associated with the self-perceived need for dental treatment in the final model. In conclusion, dental caries, dental pain, tooth loss, and family cohesion influenced the self-perceived need for dental treatment in adolescents.

Contextual and individual determinants of oral health-related quality of life among five-year-old children: a multilevel analysis.

BACKGROUND: Contextual factors may influence oral health-related quality of life (OHRQoL) in children. The aim of the present study was to evaluate the influence of individual and contextual determinants of OHRQoL based on the perceptions of children. METHODS: A cross-sectional study was conducted with a representative sample of 769 five-year-old children from public and private preschools in a city in the countryside of northeast Brazil. Parents/caregivers answered questionnaires addressing psychological aspects, sociodemographic data and aspects of the child's oral health. The children answered the child version of the Scale of Oral Health Outcomes for five-year-old children and were submitted to oral examinations. Variables related to the context were obtained from the schools and official municipal publications. Unadjusted and adjusted multilevel Poisson regression models were used to investigate associations between variables. RESULTS: In the adjusted analysis, parent's/caregiver's schooling, household income, parent's/caregiver's age, a history of dental pain, dental caries and its consequences and traumatic dental injury were considered individual determinants of OHRQoL according to the children's self-reports. After the incorporation of the contextual determinants, the association between parent's/caregiver's schooling and OHRQoL lost its significance. Type of school was the context variable that remained associated with OHRQoL. DISCUSSION: Besides the clinical and sociodemographic individual characteristics, characteristics of the school environment in which the child studies are associated with self-reported impacts on OHRQoL.

Validity and Reliability of the Brazilian Version of the Rapid Estimate of Adult Literacy in Dentistry--BREALD-30.

OBJECTIVE: The aim of the present study was to translate, perform the cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry to Brazilian-Portuguese language and test the reliability and validity of this version. METHODS: After translation and cross-cultural adaptation, interviews were conducted with 258 parents/caregivers of children in treatment at the pediatric dentistry clinics and health units in Curitiba, Brazil. To test the instrument's validity, the scores of Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) were compared based on occupation, monthly household income, educational attainment, general literacy, use of dental services and three dental outcomes. RESULTS: The BREALD-30 demonstrated good internal reliability. Cronbach's alpha ranged from 0.88 to 0.89 when words were deleted individually. The analysis of test-retest reliability revealed excellent reproducibility (intraclass correlation coefficient = 0.983 and Kappa coefficient ranging from moderate to nearly perfect). In the bivariate analysis, BREALD-30 scores were significantly correlated with the level of general literacy (rs = 0.593) and income (rs = 0.327) and significantly associated with occupation, educational attainment, use of dental services, self-rated oral health and the respondent's perception regarding his/her child's oral health. However, only the association between the BREALD-30 score and the respondent's perception regarding his/her child's oral health remained significant in the multivariate analysis. CONCLUSION: The BREALD-30 demonstrated satisfactory psychometric properties and is therefore applicable to adults in Brazil.
