Efectividad de fotopolimerización de resinas compuestas en relación al uso de las lámparas de fotocurado parte II.

Abstract

INTRODUCTION: Marginal microfiltration is the entry of bacteria and fluids to the tooth restoration interfase, triggering different causes that affect the longevity of the restoration. AIM: Determine the efficacy of the light curing of the Elipar 3M vs Bluephase Ivoclar light curing lamps in class I restorations in third molars. MATERIALS AND METHODS: This in vitro study was established with a sample of 80 healthy extracted third molars within the UCSG dental clinic in cycle B-2019. RESULTS: From the research carried out in the 8 light-cured groups with the Elipar 3M and Bluephase lamps, a total of 2 to 3 grade microfiltration was found in both lamps when light-curing at 10, 20.30 and 40 seconds at 6 mm distance. DISCUSSION: Studies conducted by Dominguez27 recommended in his study that the lamps should be placed at a distance of 2 to 6 mm for adequate photopolymerization, our results did not agree with Dominguez since the results with the highest microfiltration index were those with the greatest distance. CONCLUSION: It was concluded that when using the lamps at a greater distance, there was a lower photopolymerization of the samples which caused microfiltration in its entirety, in different grades.
