Evaluation of fissure sealing with a diluted composite sealant and an UV-light polymerized sealant after 36 months' observation.
The idea of fissure sealing has found wide acceptance in caries prevention. The present investigation was initiated to evaluate the retention of a diluted composite material used as a fissure sealant, compared with the retention of an UV-light polymerized sealant. After an observation period of 3 years, it seems justified to assume that a diluted composite sealant is a fully acceptable alternative to an UV-light polymerized sealant, and the former material seemed to have some advantages: a simpler polymerization procedure, an apparently better wear  resistance due to ceramic filler particles, and an easier recognition because of a slight discoloration.
