Uso de Compósitos pré-aquecidos como selantes de fóssulas e fissuras

Abstract

The use of sealants in pits and fissures on occlusal dental surfaces aims to prevent the formation of biofilm, and the consequent proliferation of cariogenic bacteria in places of difficult mechanical removal. Sealants are resinous materials, however, they can have different compositions, characteristics and handling methods, in addition to different reactions to wear due to time and external actions, such as: pH, chewing, parafunctions, brushing, among others. This work aims to carry out a literature review on the subject, in addition to demonstrating the technique of applying pre-heated composite resin as a pit and fissure sealant in vitro. Demonstration was carried out on the occlusal surface of artificial teeth, applied with different operative techniques and materials, using: Resin (OPUS Bulk Fill Flow, FGM), and a Resin (FiltekTM Z100Xt, 3M ESPE, USA) both were heated in a temperature of 70°C. The starting point for this study is the observation of the literature, which demonstrates that preheating the composite resin can increase the flow of regular consistency composites, which could improve the adaptation of the material in the deeper portions of pits and fissures. Thus, composite resins used as pit and fissure sealants, because they have a greater amount of filler particles, when compared to fluid resins and resin sealants, can improve the longevity of the procedures Thus, this proposal is presented with the hypothesis that the use of fluid composites in pits and fissures can increase their penetration, especially in those fissures with complex anatomical structures.
