The clinical performance of two dental materials used as pit and fissure sealants (Fluroshield and Vitremer) was evaluated. Forty-six sound upper or lower premolars were sealed. Twenty-three teeth were sealed with Vitremer and 23 with Fluroshield. After six, twelve, and twenty-four months Vitremer presented a total retention of 91.30%, 91.30%, and 82.60%, and Fluroshield presented a total retention of 100% in the three periods of evaluation. Both materials do not permit the development of caries, independent of their retention and period of evaluation.
