Perbedaan Pengaruh Ekstrak Etanol Buah Lerak (Sapindus Rarak Dc) dengan Kombinasi Naocl dan Asam Sitrat Sebagai Bahan Irigasi Terhadap Porositas Dinding Dentin Saluran Akar Gigi

Abstract

Root canal preparation generates layers of organic and inorganic materials, necessitating an ideal irrigation material. Commonly used irrigation materials are NaOCl combined with EDTA or citric acid, which can cause dentin to become porous, resulting in a reduction in dentin strength. Due to the shortcomings of these irrigation materials, a natural and more biocompatible substance such as Lerak fruit extract is needed. Lerak fruit can dissolve both organic and inorganic components while reducing surface tension, thereby increasing dentin permeability. The aim of this research is to determine the differences between Lerak extract and a combination of NaOCl and citric acid as irrigation materials in terms of the porosity of dentin walls in root canals. The research design employed a post-test control group design using 40 mandibular premolar teeth and divided into 4 groups. The samples were prepared using a manual step-back technique, then irrigated with each treatment group. Subsequently, the samples were cut buccolingually, and porosity was observed using a Scanning Electron Microscope. The first group was irrigated with 12.5% ethanol extract of Lerak fruit, the second group with 2.5% NaOCl followed by 12.5% ethanol extract of Lerak fruit, the third group with 2.5% NaOCl followed by 10% citric acid, and the fourth group with saline. Shapiro-Wilk normality tests revealed normal data distribution in groups 1 and 2, but in groups 3 and 4, the data is not normally distributed.. Levene's test indicated homogeneity of data variance. The Kruskal-Wallis test resulted in p=0.000 (p<0.05), indicating a significant influence, followed by Post Hoc tests. Based on the data irrigation with Lerak extract produced smaller porosity compared to the combination of NaOCl with Lerak and the combination of NaOCl with citric acid
