Title

LONG TERM APICAL MICROLEAKAGE

Pages

  24-27

Abstract

 Background and Aim: This invitro study compared the effect of root canal irrigants on long _ term apical seal.Methods and Materials: First, freshly extracted human maxillary centrals and canines were irrigated with 1% Nacio. Then they were rinsed with distilled water. After that, their crowns were removed at the CEJ. Then the teeth were divided into two test and two control groups. Each test group had 30 teeth and each control group had 5 teeth.The first test group was instrumented to a # 40 K MAF using the step back technique and irrigated with 2.5% sodium HYPOCHLORITE and Flared up to # 70.The second test group was instrumented to a # 40k MAF using stepback technique and irrigated with 0.2% CHLORHEXIDINE and shaped up to # 70.The positive control group was instrumented to a # 40 k MAF using stepback technique and irrigated with sterile saline and shaped up to # 70 All test groups were dried with paper points and were filled with AH26 sealer and gutta percha using lateral condensation technique. And stored at 370 for 6 months in steile saline. The root surface was coated with nail varnish (except at the apex), the negative control group was coated completely. Then they were placed in 2% methylene blue dye solution and centrifuged. The roots were sectioned longitudinally to determine the mean levels of dye pentration in each group.Results: Statistical analysis of the data showed that there significant differences between the test groups (P<0.05). However, the leakage of CHLORHEXIDINE group was more than HYPOCHLORITE group.
