Abstract

Introduction: The purpose of the root canal treatment is to obtain an appropriate apical seal for prevention of microoraganisms penetrating. The aim of this study was determining the APICAL LEAKAGE after root end resection in canals which were obturated with MTA and PORTLAND CEMENT (PC) in two different lengths.Materials & Method: In this clinical trial, the crowns of seventy single-root human extracted teeth were resected 10mm above the apex. Then, the teeth were divided into four experimental groups and two control groups. Experimental teeth canals were cleaned and flared with the crown down technique by rotary files (Easy Race), saline irrigation, and MAF#40. The whole root of group A & C were filled with MTA and PC, respectively. While, the half of root in group B & D were filled with MTA and PC, respectively. Samples in B & D groups were rapped in moist cotton and were put in incubator for 24 hours. Next, the coronal parts of canals were filled with gutta-percha & AH26 sealer. Later, all the samples were rapped in moist cotton and were put in incubator for 72 hours. After resecting the two millimeter end of all roots, and covering by Nail polish the researchers placed the teeth in 2% Methylene blue dye for 3 days. Finally, the samples were dissected longitudinally for determining dye penetration and apical seal. These were evaluated by using a stereomicroscope (with an accuracy of 0.05). The data were analyzed through using SPSS software (Kolmogrov Smirnov test and ANOVA).Result & Conclusion: It was concluded that, apical seal of PC was significantly better than MTA regardless of the filling length. Moreover, the apical seal of 5mm above the apex was better for both PC & MTA.
