Abstract

Objective: This study aimed to compare calcium loss on root canal dentin before and after EDTA application with different varians and concentration with or without surfactant.Material and Methods: Samples are mandibular premolar teeth single root canal, which is divided into 4 groups: Ethylenediaminetetraacetic Acid (EDTA) gel, cream, solution and negative control. They are decoronated in Cemento-Enamel Junction (CEJ), then prepared with Crown Down Pressureless (CDP) technique and separated bucolingual direction. One side was applied in EDTA according their respective groups and the other side was set as sample before application. Samples before and after application of each group are destructed then subsequently measured for their Ca2+’s amount using Atomic Absorption Spectrophotometry (AAS). Data were collected and analyzed using ANOVA and Tukey Post Hoc test.Results: This showed significant differences between Ca2+ amount in root canal dentin before and after application either on EDTA gel, cream, or solution as well as on negative control group (p<0.05).Conclusion: Application of EDTA solution causes the highest calcium loss compared to EDTA gel and cream.

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.
