Pit and fissure sealants can substantially reduce the occurrence of dental caries, especially preventing pit and fissure caries. The longevity and retention rate of the sealants determine their effectiveness. Sealant loss can result in the adhesion, accumulation, and fermentation of cariogenic micrograms on the tooth surface. Many studies have enhanced the retention rate of sealant and success rate of pit and fissure sealant technique. This paper summarizes clinical related factors, including tooth cleaning techniques, physical and chemical modification of tooth surface, selection of pit and fissure sealants and precautions for clinical operation, to provide reference and guidance to clinicians.

Key words: pit and fissure sealant technique, retention rate, anti-caries efficacy
