Effect of Adding Fluoride to Camellia sinensis Against Dentin Erosion Generated by Non-Bacterial Acids
Abstract
Introduction: Natural products are an option to be used in different conditions in the oral cavity, such as Camellia sinensis, which due to its different properties would be beneficial in the erosion of the dental surface.
Objetive: Determinar el efecto del extracto de Camellia sinensis (C. sinensis) adicionado con flúor frente a la acción erosiva de ácidos no bacterianos en la superficie de la dentina humana
Materials and Methods: Quasi-experimental, prospective, longitudinal, and in vitro study, consisting of 50 samples of human dentin, which were classified into 5 study groups: distilled water, hydrochloric acid, 2% C. sinensis extract, sodium fluoride. 2% and 2% C. sinensis extract added with 2% sodium fluoride. The surface roughness of each sample was evaluated with the SRT6200 digital roughness meter, obtaining a total average roughness and the measurements were carried out in two moments.
Results: It was observed that the 2% C. sinensis extract, the 2% sodium fluoride, and the C. sinensis extract added with 2% sodium fluoride, showed a variation in surface roughness between before and after, which was not significant (p<0.05) in all cases. It should be noted that the C. sinensis plus sodium fluoride group is the one that obtained the best variation in the mean surface roughness than the other groups studied.
Conclusions: The 2% C. sinensis extract, 2% sodium fluoride, and the combination of both compounds demonstrated an inhibitory effect against the erosive action of hydrochloric acid (0.01 M) on the dentin surface, not presenting a statistically significant difference in the results.
