Factores que influyen en una óptima fotopolimerización. Una revisión sistemática.

Abstract

Introduction: A determining factor in obtaining clinical success and longevity in light-curing adhesive restorations is to achieve optimum polymerization of the monomers present in the materials. Avoiding possible dental sensitivity, microleakage, fractures, detachment of the restoration and pulp toxicity, Objective: To determine the factors that influence optimal photopolymerization of composite resins. Materials and methods: The design of this systematic review article is qualitative descriptive and analytical, non experimental and documentary, deductive method. The search and collection of scientific articles was carried out from November 2021 to February 2022. There was a sample of 34 scientific articles, which could be carried out through access to the virtual library of the UCSG and other reliable and viable sources such as PubMed and Cochrane. Analysis - discussion: There are several factors that influence the correct polymerization of composite resins such as: characteristics of light curing lamps, it´s recommended that they have a minimum radiant output of 500mW/cm2, , a wide, ergonomic tip design and a lamp tip that measures 9 to 11mm in diameter, a homogeneous beam of light and a depth curing of 10mm. Operator training and maintenance are just as crucial, as is the color of the resin, which darker the tone, the more radiant energy will require for an optimal polymerization. Key words: radiance, light spectrum, collimation radiant power, light beam, radiant output, lamp maintenance, photoinitiators, training, and led lamps.O
