Parental preferences for dental caries treatment in preschool children according to socio-demographic conditions and beliefs about the primary dentition.

AIM: To assess parental preferences for dental caries treatment and its association with socio-demographic conditions and beliefs about the primary dentition. METHODS: Study design: Cross-sectional study. This study was conducted among 512 parents of 2- to 5-year-old children in the State of Tocantins, in the North Region of Brazil. A self-administered questionnaire on preferences for dental caries treatment, socio-demographic conditions and beliefs about the primary dentition was responded by parents considering two hypothetical clinical scenarios: if their child had one or more asymptomatic caries lesions (without pain), one or more symptomatic caries lesions (toothache). Poisson regression models fitted the association between explanatory variables and the preference to conservative interventions. CONCLUSION: It can be concluded that parental preferences for dental caries treatment in preschool children depend on mother's age and education level, as well as on beliefs about the primary dentition.

Non-nutritive sucking habits and their effects on the occlusion in the deciduous dentition in children.

AIM: The study evaluated the presence of non-nutritive sucking habits and and their effects on the occlusion in the deciduos dentition in Spanish children. MATERIALS AND METHODS: Study design: Cross-sectional survey. A clinical examination was performed by an experienced examiner in 275 children aged 3 to 6 years and the collected data included the presence of anterior open bite (vertical dimension), unilateral or bilateral posterior crossbite (transverse dimensions), midline deviation and sagittal relationships between incisors, molars and canines. In addition, the parents of each child completed a questionnaire about oral habits. Data analysis included descriptive statistics (frequency distribution). Statistical significance for the association between the non-nutritive sucking habits and development of malocclusion was determined using Chi-square and Fisher's exact tests. Multiple logistic regression analysis was used in order to adjust the results for confounding effects of non-nutritive habits before assessing statistical significance. RESULTS: Non-nutritive sucking habit was observed in 224 children (81.5%) and malocclusions were present in 152 children (55.2%). There were significant relationships between pacifier sucking habit and transverse dimension alteration (OR= 3.29, CI: 0.97- 11.17, p=0.044), midline deviation (OR= 3.00, CI: 1.22-7.38, p=0.013). Children with a history of finger sucking (or thumb sucking) had an increased risk of malocclusion 4.25 times higher (CI: 0.92-19.58, p=0.044) and there was a significant relationship between finger sucking and vertical relationship (OR= 8.25, CI: 2.50-27.25, p=0.001). Children with non- nutritive sucking habits had an increased risk of malocclusion 2.55 higher compared to those without non-nutritive sucking habits (p=0.004). CONCLUSION There was an impact of non-nutritive sucking habit and development of malocclusions in this sample of children.
