Efectividad de fotopolimerización de resinas compuestas en relación al uso de distintas lámparas de fotocurado.

Abstract

INTRODUCTION: The dental microfiltration is the movement of bacteria and fluids between the dental cavity and the composite. Because of this, the durability of the restoration is affected. AIM: Determine the effectivity of photopolymerization of dental composites in wisdom teeth with different light curing lamps. MATERIALS AND METHODS: This transversal in vitro study counts with a sample of 80 extracted wisdom teeth in the UCSG Clinic during Semester A 2019. RESULTS: From the 8 photopolymerized study groups with VALO (Ultradent) and LED F (Woodpecker) lamps, microfiltration prevailed in the samples light cured with the LED F lamp by 10 seconds at 0mm and 30 seconds at 6mm, where the groups entirely had filtration grades of 1 to 3. DISCUSSION: Studies carried out by Minaya, suggest that the lamp placement distance for the photopolymerization of the composite resins should be 2-6 mm, which doesn’t match with the results of this study, since a large quantity of samples from the light cured groups of 30 seconds at 6mm presented leaks. CONCLUSION: It was concluded that the time, distance of light curing and type of lamps affected the photopolymerization of the samples creating the presence of microfiltration, which were presented in several grades, where those that predominated were grade 1 and 2.
