Comparación entre fotoactivación con luz halógena y luz led en la profundidad de polimerización de las resinas Bulk Fil

ABSTRACT: The objective of this research work was to determine the comparison of photoactivation with halogen and LED light on the depth of polymerization of bulk fill resins, a descriptive, applied, and experimental study. A non-probabilistic purposive sample of 40 samples preformed 4 mm wide by 10 mm high in a stainless-steel matrix (ISO 4049) was made, the bulk fill resin (3M™ Filtek™ One Bulk Fill) was chosen, in which 20 samples for the study of depth of polymerization the same polymerized 10 by halogen light and 10 of led light led light had an average value of 3. 42 mm with a deviation of 0.23 mm and with halogen light had an average value of 3.24 mm with a deviation of 0.23 mm. The t-tests for the equality of means indicate that the difference between the means of the groups is not statistically significant and that the depth generated by the photopolymerization is not significantly affected using LED or halogen lamps, and 20 samples for the Vickers hardness study, the 10 resin samples were polymerized with a halogen light lamp for 30 seconds, 10 resin samples polymerized with led light for 20 seconds, having a distance of 1 mm, were prepared to be taken to the Vickers microhardness tester in the laboratory of materials of the productive center metal mechanic body shop (Tungurahua), the results of mean hardness 74.6 in the cylinders polymerized with halogen light, with led light a result of mean hardness 60.01. Levene's tests of equality of variances indicate that the microhardness generated by photopolymerization is significantly affected using LED or halogen lamps.
