Abstract

Background and Objectives: Nowadays, posts are widely used in the restoration of severely damaged teeth. They are considered resistant restorative features. The aim of this in vitro study was to evaluate the effect of immediate and delayed POST SPACE preparation with two different methods on apical MICROLEAKAGE.Materials and Methods: A total of 96 one-rooted extracted human teeth were used in this study. The crowns of the teeth were resected at the CEJ. Canal preparation was carried out by the step-back technique, in which file#35 was chosen as MAF and the canals were flared up to file#60. The canals were obturated with Gutta-percha and AH26 sealer using the lateral compaction technique. Then the teeth were randomly divided into 4 experimental groups, each containing 20 teeth and two positive and negative control group, each containing 8 teeth. In group A, a PEESO REAMER was used to prepare the POST SPACE immediately after canal obturation.In group B, the POST SPACE was prepared with a PEESO REAMER one week after canal obturation. In groups C and D a HEAT CARRIER was used to prepare the POST SPACE immediately and one week after canal obturation, respectively. Dye penetration technique was used to evaluate the MICROLEAKAGE. The liner measurement of dye penetration was carried out under a stereomicroscope and the data were statistically analyzed with ANOVA and LSD tests.Results: The results of the study showed that group B (peeso reamer with delay) and group C (heat carrier with immediate) had the greatest and least dye penetration, respectively, demonstrating a statistically significant difference (p=0.03). There was no statistically significant difference in dye penetration among other groups (p>0.05).Conclusion: According to the results of the present study, the most appropriate time and procedure for POST SPACE preparation is immediately after canal obturation using a HEAT CARRIER.
