The occlusal fissure of 812 permanent and primary posterior teeth of 160 retarded children were sealed with a fluid resin which was polymerized with an ultra‐violet lamp. A half mouth technique was used to evaluate the effectiveness of the sealant in the prevention of fissure caries. The 1st year, the sealant was retained intact on 73 % of the permanent teeth and on 64 % of the primary teeth. After 2 years, the sealant was retained intact on 61 % of the permanent teeth and on 40 % of the primary teeth. The retention of the fissure sealant was better on premolars than molars both in the 1st and in the 2nd year. A single application of the fissure sealant was effective in reducing fissure caries up to 2 years.
