The effects of varying the application protocol on the retention of pit and fissure sealant: a two-year clinical study

The clinical effects of procedural variations on sealant retention are evaluated, and the caries status of sealed teeth and contra-lateral control teeth is compared. Four different protocols of application were used to evaluate sealant retention and caries status after standardized radiographic and clinical diagnosis. Reexaminations were performed at 6, 12, and 24 months. High caries reductions were found for all groups; however, premolars were less affected with occlusal caries than were molars. Tooth type and caries potential of the individuals must be considered when sealants are used.
