Abstract

Tooth color is one of the factors that influence self confidence and appearance. Chemicals ingredient in whitening teeth can cause negative effects such as reduced enamel hardness, sensitive teeth and irritation of the oral mucosa. Avocados contain ascorbic acid which can be used as an alternative ingredient to whiten teeth. Objective, to determine the effectiveness of ascorbic acid in avocado (Persea americana Mill.) 100% concentration in improving tooth color with a difference of 2, 3 and 4 days immersion time in vitro. This research is a type of experimental laboratory research with pre-test-post-only control group design. The 24 post extraction premolars were used as samples immersion in tea solution for 6 days and replaced every 2 days to make discoloration. Samples were divided into 4 groups, immersion of the sample in 100% ascorbic acid within 2, 3 and 4 days, and the control group immersed in sterile aquades. Tooth color measurements before and after immersion with a spectrophotometer. One Way ANOVA test results (p <0.05) showed a significant difference between treatment groups. Post-Hoc test results can be concluded that the 2 day immersion is the most effective in improving the color of teeth with a mean rank is 39.47. From the results showed that the comparison of 2 day immersion group was the most effective for increase the color of teeth than 3 day and 4 day immersion groups.

Abstract

Teeth discoloration has been complained by most of Indonesians. A treatment of teeth discoloration can be overcome by using a bleaching treatment. Bleaching itself, can be done using a natural ingredients, for instance avocado (Persea americana Mill.),which contained an ascorbic acid for a dental bleaching. The aim of this study is to find out the effectiveness of avocado with concentrations of 30%, 70%, and 100% on a teeth bleaching. It is a laboratory experimental research using a pretest-posttest control group design. The sample used are 24 post-extraction of premolar teeth, and ascorbic acid which was taken from the avocado by an isolation method. The teeth soaked in a black tea for 6 days and replaced every 2 days, then soaked with ascorbic acid in the avocado extract 30%, 70%, 100%, and control aquades for 3 days.The degree of teeth color was measured by using a spectrophotometer. The data analysis used a discrimination test with One Way Anova and further discrimination test with Pos Hoc Anova. The results of discrimination test with One Way Anova showed the significant value was 0,019 (p<0,05), which means there was difference colour between before and after the soaking teeth treatment using the ascorbic acid in avocado with concentrations of 30%, 70%, and 100%. Based on Pos Hoc Anova test, showed that 30% and 100% concentrations of ascorbic acid is more effective than the aquades. As the 100% concentration of ascorbic acid showed a demineralization. Therefore the 30% concentration of ascorbic acid is the most effective. The ascorbic acid in avocado extract (Persea americana Mill.) with 30%, 70%, dan 100% concentrations is effective for a dental bleaching.
