Abstract

Objectives: To evaluate the effectiveness of two clinical recall intervals on caries incidence (general proposition) in preschoolers with high caries risk. And evaluate the anxiety level, (specific proposition) according to each interval employed. Methods: The sample consisted of 224 children from 3 to 5 years old, with high caries risk, according to São Paulo Municipal Health Secretariat criteria. The children were randomized into two groups: Group 1 (G1) - oral clinical examination + oral hygiene and diet guidance with recall in 4 months, Group 2 (G2) - oral clinical examination + oral hygiene and diet guidance with recal in 8 months. Anxiety level was assessed by Facial Image Scale, by an external dentist blinded to study groups and clinical characteristics. The clinical oral examination was performed by a previously trained and calibrated examiner, blinded to the study groups. The International Caries Detection and Asessment System (ICDAS) was used for detection of carious lesions. All groups were followed up for a period of 30 months, totaling seven recall visits for G1 and three recall visits for G2. For the analyzes we used a statistical program (SPSS), where Fischer and Chi-square tests were used to evaluate the proportion of children with caries lesions between the study groups at the end of the study, and also to compare the level of children\'s anxiety between study groups at the end of the study. Results: The caries incidence in children who returned every 8 months was higher than those who returned every 4 months when comparing the two groups at the end of the study (p = 0.033). The anxiety reported by the children showed a significantly greater improvement for group 1 (recall every 4 months) compared to group 2 every (recall every 8 months) at the end of the study (p = 0.027). Conclusion: Recalls intervals every 4 months for high caries risk preschoolers resulted in a lower caries incidence and also children in this same group had lower levels of anxiety. (AU)
