Abstract:

Purpose: The aim of this study was to compare retention, effectiveness in caries prevention and superficial characteristics in 2 different materials used as an occlusal sealant.

Methods: The sample consisted of 108 school children with a mean age of 7.5±1.25 years, in which 364 first permanent molars were divided into 6 groups: (1) group 1=Delton + rubber dam (used only for this group); (2) group 2=Delton + cotton rolls; (3) group 3=Prime & Bond 2.1 + Delton; (4) group 4=Vitremer with a 0.25:1 powder/liquid proportion; (5) group 5=Primer + Vitremer with a 0.25:1 powder/liquid proportion; and (6) group 6=Vitremer with a 1:1 powder/liquid proportion.

Results: After 12 months, the total retention rate for groups 6, 1, 2, 3, 4, and 5 was, respectively: 92%, 79%, 67%, 52%, 41% and 12%. For the 3 occlusal areas, retention was: 97%, 92%, 86%, 77%, 69%, and 36%. For the modified criterion, the proportion test showed a statistically significant difference (P<.05) between: groups 1 and 4; groups 6 and 2; and group 3, 4, and 5 with all others groups. Considering the total of 3 areas, there was a statistically significant difference (P<.05) between: groups 1 and 6 with groups 3 and 4; group 2 with group 4; and groups 6 and 5 with the others.

Conclusion: The resin-modified glass ionomer cement may be a promising alternative as an occlusal sealant.
