PENGARUH PENGGUNAAN LARUTAN SODIUM KLORIDA 0,9%, ALKOHOL 96%, DAN AIR DESTILASI SEBAGAI BAHAN INTERMEDIATE FLUSHES SALURAN AKAR TERHADAP KEBOCORAN APIKAL OBTURASI SALURAN AKAR

In root canal treatment combination of several irrigation is using to get the best result of root canal treatment. NaOCl combined with CHX produces orangebrown precipitate called parachloroaniline. The purpose of this study was to determine the effect of the use of sodium chloride 0.9%, alcohol 96%, and distilled water as an intermediate flushes of apical leakage on root canal obturation. This study using 20 premolars which were prepared and randomly divided into four groups, each group consisting of five teeth. Group I was irrigated using 17% EDTA, 2.5% NaOCl and 2% CHX. Group II was irrigated using 17% EDTA, 2.5% NaOCl, 96% alcohol and 2% CHX. Group III was irrigated using 17% EDTA, 2.5% NaOCl, sodium chloride 0.9%, and 2% CHX. Group IV was irrigated using 17% EDTA, 2.5% NaOCl, distilled water, and 2% CHX. Irrigation solution and intermediate flushes are used as much as 2.5 ml, followed by sealer application (AH plus). Obturation using vertical condensation techniques (warm gutta-percha). Furthermore, the tooth root surface is coated with a layer of sticky wax and two coats of nail polish except the apical. The study subjects were stored in an incubator at 37 ° C for 48 hours, and immersed in a solution of 2% methylene blue for 24 hours. Teeth were sectioned longitudinally and apical leakage was observed using stereomicroscope of 120x magnification. The longest penetration of the dye was used as data. The results of one way anova and LSD test showed that there was the influence of the use of sodium chloride 0.9%, alcohol 96%, and distilled water as an intermediate material flushes of root canal obturation of the root canal apical leakage (p
