Associated to the scholarship:16/13972-9 - Impact of two recall intervals associated to oral health counseling on dental caries incidence, anxiety and quality of life of preschool children with high caries risk: randomized clinical trial, BP.DR


Objectives: Evaluate caries incidence in high caries risk preschool children in a randomized clinical trial with two different recalls intervals and carry out a retrospective study to investigate the risk factors that most contributed to the development of new caries lesions in this population. Methods: The sample was composed of 224 high caries risk children from 3 to 5 years old, enrolled in municipal schools of early childhood education in São Paulo city, who agreed to participate of the study. At the baseline children underwent to dental clinical examination and caries lesions were diagnosed using ICDAS score and its caries lesion activity criteria. All cavited lesions were treated. Moreover, all children and their parents received oral hygiene and diet orientation. After that, children were randomly assigned in two groups: Group 1 (G4) - oral clinical examination and recall intervals every 4 months and Group 2 (G8) - oral clinical examination and recall intervals every 8 months. At every recall interval children underwent to dental clinical examination when new caries lesions were diagnosed using ICDAS score and hygiene and diet orientation were reinforced. All these children were followed up for a period of 30 months. All analyzes will be performed under the supervision of Prof. Dr. Kim Ekstrand at University of Copenhagen by intention to treat (ITT) and considering sensitivity analysis to evaluate the differences between ITT analyzes and analyzes by protocol.
