Abstract

Objective: The aim of this study was to examine the potential of 10% strawberry gel in reducing extrinsic discoloration of composite resin.Material and Methods: This was a laboratory experimental study using 40 composite resins molded in 8-mm diameter and 2-mm thickness. Samples were soaked in coffee solution for 7 days to obtain discoloration and checked by VITAPAN classical®shade guideand adobe photoshop CS4 Version 11.0 by CIEL*a*b method. The discolored samples were randomly divided into two groups of 20 samples of each group. Group I was treated with 10% strawberry gel for  8 hours every day in 12 consecutive days and Group II as control group was treated with 10%carbamide peroxide in the same way as group 1.The color change was evaluated on day 3, 6, 9, and 12.Results: The results showed a significant change of the color in each group according to Friedman test (p<0,05) while no significant color change difference of Group I when compared to Group II based on the results of Mann-Whitney test. Either 10% strawberry gel or10% carbamid peroxide could not return the composite resins color into the baseline.Conclusion: 10% strawberry gel has similar potency as 10% carbamid peroxide in reducing extrinsic discoloration of composite resin.

Abstract

Objective: The purpose of this study was to evaluate the effect of herbal alternatives, extract of sidaguri (sida rhombifolia) combine with extract of jatropha sap (jatropha curcas) application on microhardness and morphology of tooth surface. Material and Methods: Twelve upper first premolar teeth were used in this study, prepared to Class I box cavities, and were then allocated into 4 groups (n=3). Group 1-3 were treated groups, applied with combined extracts of a small dose (5 mg), medium dose (25 mg), and high dose (50 mg), while group 4 was the control group. The cavities were restored with composite resin, immersed in artificial saliva, and stored at room temperature for 14 days. The fillings and extracts were removed and cleaned under running tap water. The teeth were cut in a vertical direction towards the apex, sectioned into 1 mm thickness, and evaluated using Laser Scanning Microscope (LSM), then were examined for microhardness test. Results: All treated groups showed significantly lower microhardness than the control group. Tooth porosity was observed, and its extensiveness was affected by doses of extracts. Conclusion: The application of herbal alternatives (extract of sidaguri and jatropha) lowered the microhardness of tooth structure and caused tooth porosities.
