Resumen
Antecedentes: Hoy en día para uso odontológico se han introducido nuevas resinas compuestas, llamadas "bulk fill", con la finalidad de permitir un incremento único de resina, sin alterar las propiedades físicas y mecánicas de estás. Estas resinas compuestas son fotopolimerizadas por fuente de luz tipo L.E.D. En Chile existen estudios sobre la profundidad de fotocurado, pero no estudios que avalen la efectividad de estas lámparas en este tipo de resinas.
Justificación: Evaluar la efectividad en la profundidad de polimerización de distintas lámparas LED en resinas, se fundamenta en la necesidad de valorar la eficiencia y eficacia de las lámparas de alta potencia. Objetivo: Determinar la efectividad del uso de diferentes lámparas de alta potencia en la profundidad de fotocurado de resinas compuestas tipo bulk fill realizadas in vitro. Material y Métodos: Estudio de abordaje cuantitativo, estudio comparativo: in vitro con cuatro grupos de intervención; dos grupos de resina de 4mm y dos grupos de resina de 5mm de espesor por 6mm de diámetro. La muestra estuvo constituida por 40 bloques de resinas compuestas que cumplieron con los estándares definidos en la investigación. Los resultados de las mediciones fueron comparadas con el protocolo que indica el fabricante y las medidas expresadas por el micrometro. Con la finalidad de evitar sesgos de medición se realizó una prueba piloto mediante la calibración del investigador con un experto, con valores de correlación de 0.98. Para el procesamiento de los datos, se utilizó un software estadístico SPSS v.22 y utilizando técnicas de análisis descriptivo e inferencial con uso de test T-student para evaluación de diferencias de medias, previo análisis de normalidad (test de K-S p>0.05).
Resultados: La efectividad del uso de las diferentes lámparas en la profundidad del fotocurado medidas en espesores de 4 y 5mm en resinas tipo bulk fill no muestra diferencias estadísticamente significativas entre la lámpara Valo Cordless con la Coltolux LED. A su vez al comparar la lámpara LED Coltolux Colteme 4 y 5mm, y por otro lado la Valo Cordless 4 y 5mm, si existieron diferencias significativas en la efectividad de la profundidad fotocurado.
Background: Nowadays for dental use new composite resins, called "bulk fill" have been introduced, in order to allow a single increase of resin, without altering the physical and mechanical properties of these. These composite resins are photopolymerized by light source type L.E.D. In Chile there are studies on the depth of photocuring, but there are no studies that support the effectiveness of these lamps in this type of resins. Purpose: To evaluate the effectiveness in the polymerization depth of different LED lamps in resins, is based on the need to evaluate the efficiency and effectiveness of high power lamps. Objective: To determine the effectiveness of the use of different lamps of high power in the photocuring depth of composite resins made in bulk fill type made in vitro. Material and Methods: Quantitative approach study, comparative study: in vitro with four intervention groups; two groups of resin of 4mm and two groups of resin of 5mm of thickness by 6mm of diameter. The sample consisted of 40 blocks of composite resins that met the standardizations defined in the research. The results of the measurements were compared with the protocol indicated by the manufacturer and the measurements expressed by the micrometer. In order to avoid measurement biases, a pilot test was performed by calibrating the researcher with an expert, with correlation values of 0.98. For the data processing, statistical software SPSS v.22 was used and using descriptive and inferential analysis techniques using T-student test for evaluation of mean difference, after normality analysis (KS test p> 0.05). Results: The effectiveness of the use of the different lamps in the photocuring depth measured in thicknesses of 4 and 5mm in bulk fill resins shows no statistically significant differences between the Valo Cordless lamp and the Coltolux LED. In turn, when comparing the Coltolux Colteme 4 and 5mm LED lamps and, on the other hand, the Valo Cordless 4 and 5mm, if there were significant differences in the effectiveness of the photocured depth.
