Abstract

The effect of preventive pit and fissure sealants with a resin-based material on the number of salivary mutans streptococci was evaluated in 46 healthy 12-year-old school children (F group) with medium or high counts during a 1-year study period. As controls served 33 children of the same age with the same bacterial levels at baseline (C group) and 55 children with low levels (L group). Caries prevalence and incidence were registered clinically and radiographically. Sealing of all accessible pit and fissures was carried out in the F group with a light-cured Bis-GMA sealant. Bacterial levels at baseline and 3, 6, 12 and 52 weeks after treatment were estimated with a chairside method. The results disclosed a significant (P < 0.05) drop in the number of salivary mutans streptococci in the F and C groups at all sampling occasions compared to baseline. There were however no differences between the groups during the study period. Both the caries prevalence and incidence were significantly (P < 0.05) higher in F and C groups when compared to the L group. The results suggest that preventive pit and fissure sealing with a resin based material does not affect salivary mutans streptococci levels.
