Single sealant treatment against dental caries provides long-term prevention

In this study, high-caries-risk children between the ages of 8 and 10 were examined. The children in the preventive group developed caries lesions on the distal surfaces of their primary second molars (05d), but their mesial surfaces of their approximate permanent first molars were in good health (6m). The children in the therapeutic group exhibited early caries lesions on 6m that bordered lesions on 05d. The two groups of kids each had one pair of 05d/6m shoes. One 6m surface from each pair was randomly chosen to get sealing using a split-mouth design, while the other pair acted as an unsealed control.

The key findings of this study were:

1. 42 of the 61 baseline children were able to undergo blind clinical and radiographic evaluations both at baseline and five years afterwards.

2. In the P group, caries lesions had formed on 8 of the 28 (28.6%) sealed and 15 of the 28 (53.6%) unsealed sound 6m surfaces (p = 0.04).

3. In the T group, 4 of 14 sealed (28.6%) and 8 of 14 (57.1%) unsealed caries control surfaces showed the advancement of the carious lesions on 6m (p = 0.29).

4. When the data from the two groups were combined, there was a significant difference between sealed and unsealed surfaces (p = 0.013).
