Evaluación in vitro del nivel de pigmentación en la capa superficial de las resinas nanohíbridas composita brilliant NG (Colrene), composita opallis (FGM) mediante la aplicación de glicerina versus pulido convencional.

The resins are affected by many factors such as the presence of an inhibited layer of oxygen which contributes to the last layer of resin to have a partial polymerization which brings problems such as surface pigmentations. Objective: Determine the surface pigmentation in monohybrid resins which are subjected to the glycerin application versus conventional. Methods: 40 disc samples with 10 mm diameter and 2 mm thickness were made, which were distributed in 4 groups of 10 samples each one. The first group: Composite Brilliant NG resin discs (Coltene) with glycerin application. Second Group: Composite Opallis resin discs (FGM) with glycerin application. Third group: resin discs will be Composite Brilliant NG (Coltene) with the conventional polishing application. Finally, the group four: resin discs of Composite Opallis (FGM) with the conventional polishing application. The samples were exposed for 3 hours a day for 15 days in a pigmenting agent (black soda). The color of the samples was taken before and after being submerged in the pigmenting agent through Vita Easy-shade V and we used the Shapiro-Wilk, Wilcoxon, Kruskal Wallis test for the statistical analysis. Results: The samples with conventional polishing were pigmented in a larger scale (5 to 10) while the ones which were applied glycerin were pigmented in a smaller scale (1 to 3) Conclusion: The glycerin application helps to reduce the pigmentation of the resins. Key words: Glycerin, oxygen, polymerization.
