    Abstract:
    PURPOSE: The purpose of this clinical trial was to test the use of a primer and bonding agent to increase the retention of a fissuresealant in a group of Kuwaiti children. METHODS: In 78 6- to 9-year-old children who required sealants in all 4 permanent frst molars, sealants were placed in 2 teeth using a primer and bond (3M Scotch Bond) and in 2 teeth without primer and bond. Sealant retention was evaluated 1 and 2 years later. Sealant retention was scored as: (1) complete retention; (2) partial loss of sealant; and (3) complete loss of sealant Caries was scored for those teeth in which the sealant was partially or completely lost RESULTS: At the 2-year examination, in teeth sealed with primer and bond (a) 64% of the sealants were completely retained; (b) 23% were partially lost; and (c) 13% were completely lost. In teeth sealed without primer and bond: (a) 68% of the sealants were completely retained; (b) 20% were partially lost; and (c) 12% were completely lost There was no difference in sealant retention (P=.22) and caries (P=.56) in teeth sealed with and without bond. In multivariate analyses after controlling for age, gender, tooth surface, and arch, no differences in sealant retention and caries were seen. CONCLUSION: If a proper technique is used in sealant placement, primer and bond does not enhance sealant retention.
