Noninvasive control of dental caries in children with active initial lesions. A randomized clinical trial.

The aim of this study was to investigate whether DMFS increment can be decreased among children with active initial caries by oral hygiene and dietary counseling and by using noninvasive preventive measures. Except for mentally disabled and handicapped children attending special schools, all 11- to 12-year-olds in Pori, Finland, with at least one active initial caries lesion were invited to participate in the study and were then randomized into two groups. Children in the experimental group (n = 250) were offered an individually designed patient-centered preventive program aimed at identifying and eliminating factors that had led to the presence of active caries. The program included counseling sessions with emphasis on enhancing use of the children's own resources in everyday life. Toothbrushes, fluoride toothpaste and fluoride and xylitol lozenges were distributed to the children. They also received applications of fluoride/chlorhexidine varnish. The children in the control group (n = 247) received basic prevention offered as standard in the public dental clinics in Pori. For both groups, the average follow-up period was 3.4 years. A community level program of oral health promotion was run in Pori throughout this period. Mean DMFS increments for the experimental and control groups were 2.56 (95% CI 2.07, 3.05) and 4.60 (3.99, 5.21), respectively (p < 0.0001): prevented fraction 44.3% (30.2%, 56.4%). The results show that by using a regimen that includes multiple measures for preventing dental decay, caries increment can be significantly reduced among caries-active children living in an area where the overall level of caries experience is low. 2007 S.
