Influencia del uso de la glicerina en la estabilidad del color de una resina compuesta, estudio in vitro.

The preservation of chromatic character in composite resins is essential in the dental context. The study aimed to determine the influence of the use of glycerin within restorative protocols on the color stability of composites. The type of research adopted was in vitro, cross-sectional, and with a quantitative approach; observation was used as the data collection technique, and a laboratory logbook served as the instrument. The sample consisted of 30 specimens, divided into two groups of 15 elements each: Ga (control group) - specimens without glycerin application, and Gb - specimens with glycerin application in the final increment. Upon completion of the experimental phase, it was observed that the p-value was 0.032, which demonstrates that there were statistically significant differences between both groups. This indicates that glycerin plays an important role in the preservation of color over time, in addition to helping to form a barrier against oxygen, mitigating the progressive formation of the oxygen-inhibited layer, and optimizing surface polymerization. It is concluded that the administration of glycerin during the photopolymerization process constitutes a procedure of great clinical relevance, as it optimizes each of the aesthetic and functional results, which translates into better preservation and longevity of restorations, thus laying the foundation for subsequent research in clinical settings.
