Title

A INVITRO INVESTIGATION ON THE INCIDENCE OF APICAL LEAKAGE AFTER USING CALCIUM HYDROXIDE AS AN INTRACANAL DRESSING

Pages

  7-13

Abstract

 Background and aim: Nowadays CALCIUM HYDROXIDE is used as a dressing for canal sterilization and repair progression of apical lesions. The aim of this study was to determine the incidence of APICAL LEAKAGE after susing CALCIUM HYDROXIDE as an intracanal dressing and filling the canal with gutta percha and AH26 sealer.Materials and Methods: The crowns of fifty-eight single-root extracted human teeth were resected and then divided into three test groups and two control groups (test groups=15 teeth, positive control=3 teeth, negative control=10 teeth). The canal of each tooth was prepared using step-back technique upto 50≠ k-fileand MAF=30 in groups A and C, MAF=30 in group B.The teeth of groups Band C were filled with CALCIUM HYDROXIDE for one week and then the paste was removed by 35≠ file and irrigated with normal salin in group B and sodium hypochlorite in goup C.Then canals of test groups and negative control were obturated with gutta percha and AH26sealer using lateral condensation technique. Following this, teeth were centrifuged in India ink before floating in it for three days. Specimens were sectioned vertically and examined under a STEREOMICROSCOPE to measure dye - penetration level. The results were analyzed using ANOV A statistical test.Results: Dye - penetration of group C in which CALCIUM HYDROXIDE. paste had been removed with sodium hypochlorite was less than two other groups, however, no statistically significant difference was found between three experimental groups of A, Band C in dyepenetration.Conclusion: It can be concluded that using CALCIUM HYDROXIDE for canal sterilization has no effect on the level of APICAL LEAKAGE.
