Comparative analysis between resin sealant and ionomer by scanning electron microscope

AbstractIntroductionThe sealing of occlusal surfaces as an effective procedure in the prevention of dental caries, its recognition since 1976 by ADA, has been used as a preventive, safe and effective method.ObjectiveThis study aimed at analyzing the products used as pit and fissure sealant of human teeth, which noted concern, is the property of penetration and porosity viewed in the scanning electron microscope (SEM).Material and methodThere was sealing of 40 pre-molars, previously submitted to prophylaxis with pumice stone and water and separated into two groups of twenty teeth each. In one of the groups was used sealant polymerized by light Fluroshield ® and in another, glass ionomer cement Vidrion R ® and ten remaining teeth as control. After those procedures are implemented, the teeth were cutted transversely by precision saw, samples were cleaned, fixed and then observed in SEM.ResultAs a result, the resin sealant fotopolimerizável showed greater penetration in 71.5% of the samples, reaching the region's deep fissure, and better adherence and less porosity, while the glass ionomer cement, used as a sealant, had higher porosity and in none of the samples struck the fissure deeper region.ConclusionThe resin sealant has better properties in the questions discussed.
