Resumen : Comparación de la contracción de polimerización entre una resina incremental y una Bulk Fill, utilizando el sistema adhesivo universal…
Descripción : The bulk fill resin is a relatively new material, with the main characteristic that restorations can be made in a single 4 mm increment, thus improving the professional's working time. Therefore; the properties of the material such as peripheral sealing, contraction, depth of curing, color and strength, they need a more thorough analysis to verify that it is a suitable material to use in patients. In the following study, the contraction volume analysis of the material was performed by comparing the conventional resin and the bulk fill resin. For which 40 third molars were divided into 4 groups: Group 1: Bulk Fill Resin Without Adhesive (RBS), Group 2: Conventional Resin Without Adhesive (RCS), Group 3: Bulk Fill Resin With Adhesive (RBC), Group 4 : Conventional Adhesive Resin (RCC), which was placed on a plaster mold; after that, class 1 cavities were made on the teeth, and, the adhesion protocol was carried out, on the RBC and RCC groups, and then restore them with Filtek TM Bulk Fill 3M ESPE resin for RBS and RBC groups, and with Filtek TM Z350 XT resin, for RCS and RCC groups. Afterward the tomography of each group was carried out in their two states before and after polymerization, once the images were obtained, they were uploaded to the AMIRA 3D Program to perform a reconstruction of these in 3D format and starting to analyze them. The obtained results were analyzed in the MINITAB statistical program, through a general linear analysis. Where it was found that conventional resins have a 2.2275 percent shrinkage and Bulk fill resins 1.8775 percent, that when a statistic analysis was obtained a P-value 0.447 being greater than our significance value P-Value 0.05 , resulting in that there is no significant difference between the resins, in addition to this it is confirmed that the universal adhesive system helps to reduce the volume of contraction.
