Factors associated with the survival of primary maxillary anterior teeth after intrusive luxation: a retrospective longitudinal study.

PURPOSE: To evaluate the survival rate of primary maxillary anterior teeth following intrusive luxation and identify associated factors. METHODS: A retrospective longitudinal study was conducted at a primary dental trauma centre using 88 dental records of children with intrusive luxation between 2007 and 2018. The variables of interest were time the tooth remained in the alveolus, degree of intrusion, accentuated overjet, lip protection, visible plaque, compromised germ of the permanent successor, clinical signs of infectious and inflammatory processes, endodontic treatment, pulp canal obliteration, sex, age at the time of trauma, family income, mother's schooling, and immediate care. Descriptive, bivariate, and Cox regression analyses were performed (p < 0.05; 95% CI). RESULTS: The 88 dental records of children with intrusive luxation included 128 teeth. Survival rate throughout the follow-up period was 65.6% (n = 84). Age older than three years and eight months (HR 2.28; 95% CI 1.04-4.99; p = 0.039), the development of an infectious process (HR 3.51; 95% CI 1.39-8.86; p = 0.008), development of an inflammatory process (HR 2.35; 95% CI 1.17-4.71; p = 0.016) and compromised germ of the permanent successor (HR 4.38; 95% CI 1.99-9.61; p < 0.001) were associated with a lower survival rate of intruded primary maxillary anterior teeth. CONCLUSION: The survival rate during the follow-up period of intruded primary maxillary anterior teeth was considered high. A significantly lower survival rate was associated with age, the occurrence of an infectious process and inflammatory process, and the compromised germ of the permanent successor.

Impact of untreated dental caries and dental pain on sadness related to oral health of Brazilian children.

PURPOSE: Children should feel sad when they believe that a negative outcome is permanent. The sadness that an oral problem might bring tends to contribute to children's loneliness and increase the social stress levels. The aim of this study was to evaluate the impact of untreated dental caries, dental pain, malocclusion, and traumatic dental injury on prevalence of sadness related to oral health among Brazilian children. METHODS: This cross-sectional study was carried out with 397 children aged 8-10 years randomly selected from public and private schools in Diamantina, Brazil. The Brazilian version of the CPQ8-10 was applied. Sadness was collected through the question, "In the last month how often did you feel sad because of your teeth or mouth?" and dental pain through the question, "In the last month, how many times have you had pain in your teeth?" One calibrated examiner (Kappa value intra examiner: 0.77-0.91; Kappa value inter examiner: 0.80-1.00) performed the exam for dental caries (DMFT), malocclusion (DAI), and dental trauma (O'Brien). Parents answered questions addressing socioeconomic issues. Descriptive analyses, Chi-square test, and hierarchical Poisson regression models were performed (IC 95%; p < 0.05)." RESULTS: The prevalence of sadness related to oral health was 30.5% (n = 121). Sadness related to oral health was associated with untreated dental caries (PR: 1.46; 95% CI 1.32-2.46; p = 0.001 ) and dental pain (PR: 2.91; 95% CI 2.00-4.22; p < 0.001). Other clinical variables analyzed (traumatic dental injury and malocclusion) were not significantly associated with sadness related to oral health. CONCLUSIONS: Children with untreated dental caries and dental pain presented a higher report of sadness related to oral health.

Malocclusion in preschool children: prevalence and determinant factors.

PURPOSE: To evaluate the prevalence of malocclusion and associated factors in the primary dentition of preschoolers in the city of Diamantina, Brazil. METHODS: A cross-sectional study was carried out with 381 children aged 3-5 years treated at the 10 basic health care units in the city during immunisation campaigns. The dependent variables (presence of malocclusion, open bite, crossbite and crowding) were evaluated through a clinical oral exam. The independent variables (gender, age, health problems, breastfeeding, bottle feeding, harmful oral habits, mother's schooling, household income and number of children in the home) were collected through interviews. Statistical analysis involved descriptive analysis, Chi square test and Poisson regression. RESULTS: The prevalence of malocclusion was 32.5%. Open bite was the most frequent type of malocclusion. Children with a history of bottle feeding (PR 1.74; 95% CI 1.24-2.44) and those with harmful oral habits (PR 1.49; 95% CI 1.23-1.99) had greater prevalence rates of malocclusion. Greater prevalence rates of open bite were also found in children with a history of bottle feeding (PR 5.00; 95% CI 1.99-12.5) and those with harmful oral habits (PR 2.90; 95% CI 1.59-5.29), whereas greater prevalence rates of crossbite were found in boys (PR 1.79; 95% CI 1.10-2.91) and were associated with mother's schooling (PR 1.91; 95% CI 1.20-3.06). CONCLUSION: A history of bottle feeding and the presence of harmful oral habits were identified as determinants for the occurrence of malocclusion in preschoolers.

Impact of early childhood caries on the oral health-related quality of life of preschool children and their parents.

The aim of the present population study was to evaluate the impact of early childhood caries (ECC) on the oral health-related quality of life (OHRQoL) of preschool children and their parents/caregivers. A random sample of 638 children (aged 2-5 years) underwent a clinical oral examination to assess ECC, and their parents were invited to answer two questionnaires: one on the OHRQoL of the child, the Early Childhood Oral Health Impact Scale, and another on the characteristics and sociodemographic conditions of the child. Descriptive analysis, χ(2) test, Mann-Whitney test, Kruskal-Wallis test, and hierarchically adjusted Poisson regression models were used. The prevalence of ECC was 52.2%. The number of teeth with decay ranged from 1 (n = 42; 6.6%) to 20 (n = 5; 0.8%), averaging 2.86 (SD = 4.04). There was a significant difference between the severity of ECC and OHRQoL in terms of the impact on both child and family (p < 0.001). An increase in the severity of ECC resulted in an increased negative impact on the quality of life of the child (rate ratio, RR = 5.32; 95% confidence interval, CI: 3.67-7.71). Greater age of the mother had a positive impact on the OHRQoL of preschool children (RR = 0.72; 95% CI: 0.54-0.97). Increased age resulted in an increased negative impact on the quality of life of the child (RR = 2.97; 95% CI: 1.61-5.47). ECC has a negative impact on the OHRQoL of children aged 2-5 years and their parents. Mothers aged 30 or older reported better OHRQoL, independent of the presence of ECC and the age of the child.
