Pengaruh gel ekstrak batang nanas (Ananas comosus L.Merr) terhadap tingkat warna putih dan kekasaran permukaan gigi (in- vitro)

Abstract

Bleaching is a teeth whitening procedure by changing the color to be whiter and brighter. Natural bleaching agents that have been studied to whiten teeth are pineapple stems because they contain the active compound bromelain enzyme and have been shown to have a changing effect on tooth brightness. The purpose of this study was to determine the effect of applying pineapple stem extract gel at concentrations of 75%, 50% and 25% on changes in color level and tooth surface roughness. Laboratory experimental research method with pre-test post-test control group design. Pineapple stem extract gel was made by maceration extraction method and then divided into concentrations of 75%, 50% and 25% and added triethanolamine so that the pH of the gel became 6. Teeth were discolored for 7 days using coffee solution. Gel application was carried out for 8 hours per day on the entire tooth surface, repetition of application was carried out for 14 days at room temperature. Data analysis used the Wilcoxon non parametric test to see the effect of color level and tooth surface roughness, to see differences in the effect of color level and tooth surface roughness, the Kruskal Wallis test was performed and continued with the Mann-Whitney test. The results showed that all treatment groups after applying pineapple stem extract gel experienced significant changes in color level values (p<0.05). The greatest change in tooth color level was found in the 75% concentration. There was no significant effect on tooth roughness after applying pineapple stem extract gel except for the 75% concentration. It can be concluded that pineapple stem extract gel can improve tooth whiteness without causing an increase in tooth surface roughness.
