Profundidad de polimerización de lámparas utilizadas en la clínica de odontología UCSG, estudio in vitro.

Abstract

INTRODUCTION: To achieve optimal polymerization of composite resins, a material widely used in dentistry today, the characteristics of light-curing lamps are very important. The depth of polymerization that they provide is a determining factor for the clinical success of the restorations. OBJECTIVE: To measure the depth of polymerization of lamps used in the UCSG dental clinic. MATERIALS AND METHODS: For the study, 10 lamps were used and later 10 groups of 20 resin specimens were made using a stainless-steel mold. For each lamp to be evaluated, 10 Brilliant EverGlow OA3 resin specimens and 10 Brilliant EverGlow A1/B1 resin specimens were made. These 10 specimens were divided into two groups of 5, light-curing each one at different distances: 0mm and 10mm respectively, measured from the tip of the lamp to the resin. RESULTS: The resin that achieved the greatest depth of cure was the Brilliant EverGlow A1/B1 resin. It was found that the distance from the tip of the lamp to the objective radically influences its level of polymerization. The irradiance of the lamps was not related to the depth of cure. The Bluephase N ivoclar vivadent lamp achieved the greatest depth of cure. On average, the thickness of the composite that polymerizes for the A1/B1 shade was 2mm, while for the OA3 shade it was 1mm. CONCLUSION: There are differences in the characteristics of the lamps in their polymerization, the low-cost ones gave the lowest values of curing depth.
