3-year survival rates of retained composite resin and ART sealants using two assessment criteria.

The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled clinical trial consisted of 123 schoolchildren, 6-7-years-old. At baseline, high-caries risk pits and fissures of fully erupted first permanent molars were treated with CR and ART sealants.

Exploring the association between feeding habits, non-nutritive sucking habits, and malocclusions in the deciduous dentition.

Background: This study aimed to explore the association between feeding habits, non-nutritive sucking habits, and malocclusions in deciduous dentition.

Methods: A cross-sectional observational survey was carried out in 275 children aged 3 to 6 years and included clinical evaluations of malocclusions and structured interviews. Statistical significance for the association between feeding habits and the development of malocclusion was determined using chi-square and Fisher's exact tests.
