Clinical Evaluation of Two Materials Used as Pit and Fissure Sealants: 2-Year Follow-Up
Authors: Enrico Cogo and Giorgio Calura
Abstract: Purpose. This longitudinal study evaluated two different materials used as fissure sealants for 2 years after clinical application: a flowable composite resin (Tetric EvoFlow) and a conventional resin sealant (Concise Light Cure White Sealant). Methods. In all, 346 sealants were placed on 142 sound primary molars (Gp) and 204 permanent molars and premolars (GP) of 52 patients aged between 8 and 19 years. In every patient, the teeth on the left side of the mouth (173) were sealed with Tetric EvoFlow (GTF) and the teeth on the right side (173) with Concise (GC). The sealants were evaluated at baseline, and 6, 12, 18, and 24 months after placement with an explorer under 4.5× magnification by a blind examiner. Results. At the 2-year follow-up, 30 sealants were totally lost and 46 has lost the marginal integrity. For primary dentition, no difference exists between Tetric EvoFlow and Concise. For permanent dentition, the retention rate and marginal integrity rate were significantly higher with Tetric EvoFlow.
