Effectiveness of fissure sealant retention and caries prevention with and without primer and bond.
OBJECTIVE
This study evaluated the effectiveness of sealant retention and caries prevention with and without primer and bond below the fissure sealant among Kuwaiti schoolchildren.


METHODS
This clinical trial used fissure sealant that was applied to four sound first permanent molars on 78 children. All the teeth were cleaned with pumice and rubber cups, isolated with rubber dams, and etched for 20 s. In a split-mouth study design, for the test teeth (n = 156), primer and bond (3M Scotchbond Multi-Purpose Plus System primer and bond) were applied below the sealant, and for the control teeth (n = 156), only sealant (Delton Plus) was applied. The number of tooth surfaces included was 480. Due to loss to follow-up, only 60 children were evaluated at 5 years for sealant retention and caries. The evaluation criteria were: completely retained sealant, complete or partial sealant retention, and caries.


RESULTS
In teeth sealed with primer and bond, 47 (19.6%) tooth surfaces had completely retained sealant, 60 (9.2%) teeth had partially retained sealant, while in 51 (21.3%) caries was prevented and 120 (50%) tooth surfaces were carious or filled. In teeth sealed without primer and bond, 25% (60 tooth surfaces) had completely retained sealant, 6% (14 teeth surfaces) had partially retained sealant, 26% (54 teeth surfaces) showed caries prevention, and 49.6% (119 tooth surfaces) were carious or filled. There was no difference between teeth sealed with primer and bond (120 teeth) and teeth sealed without primer and bond (120 teeth) in completely retained sealant (p = 0.15), complete or partial sealant retention (p = 0.6), caries prevented (p = 0.37), and caries (p = 0.93).


CONCLUSIONS
Caries prevention was not enhanced in teeth sealed with primer and bond sealant compared with those sealed with sealant alone.
