Fotopolimerização das resinas compostas e fatores que influenciam seu desempenho restaurador

Abstract

Introduction: Composite resins demonstrate success in several areas of dentistry, and the search for improvements in these materials as well as their understanding are necessary for the correct use by the dental surgeon. Objective: To identify and describe the main factors related to photopolymerization that influence the durability and clinical success of composite resin restorations. Furthermore, the most common clinical implications resulting from failures in the polymerization process of restorative materials in dental treatment were adressed. Methodology: A search was carried out in the Pub Med, Google Academic, SciELO and EBSCO database through the BDU (UniCesumar Digital Library). The inclusion criteria were: articles in the period from 2000 to 2024. The exclusion criteria were: articles without a summary, articles whose language was not English and Portuguese, articles from journals that did not belong to the dental area. Literature review: It was possible to observe in articles the implications that cause restoration failures, such as polymerization contraction and low levels of microhardness, some factors such as the law of exposure reciprocity, choice of adequate LCU, its maintenance and use, in addition to techniques that aim at a better insertion and generate an increase in the pre-gel phase demonstrate to convert into satisfactory results. Conclusion: We can understand that obtaining a material with desirable clinical properties is obtained through a relationship between several factors that complement each other, involving photopolymerization, resin composition and and restorative techniques.
