Evaluation of Coronal Micro-Leakage of Fiber Post with Different Luting Cements (In Vitro Study)

Abstract

Background and Objectives: This research's objective was to analyze coronal micro-leakage of fiber post using the various types of luting cements. Methods: Thirty extracted mandibular single rooted premolars underwent instrumentation with rotary protaper ® system and obturated with protaper ® gutta-percha and AH-plus ® root canal sealer. After being incubated for twenty-four hours, the post space preparation was done through the usage of the Unicore ® post drill #2 forming 8mm deep post space and the identical size of Unicore ® fiber post #2 was positioned. The samples that went through preparation were arbitrarily placed within three groups representing the three kinds of luting cement (G1: RelyX Unicem, G2: TotalCem, G3: GC Fuji I). Two layers of nail polish were placed upon the root's surfaces. However, the coronal 2mm was not painted, and the samples were individually placed within 10% black Indian ink dye for the time period of seventy-two hours. The samples underwent rinsing and removal of nail polish, after that the clearing and decalcifying of the samples were performed. One Way Analysis of Variance (ANOVA) used to test any statistically significant difference among the groups also Turkey's HSD (Honest Significant Difference) post hoc multiple comparison test used for comparison among the groups after using ANOVA test. Results:The results of the present study showed that groups luted with G1 and G2 better coronal sealing than group which luted with G3, which presented that no statistically noteworthy variances were identified among G1 and G2, but substantial variances were present among (G3) further groups. Conclusion: TotalCem ability for coronal sealing surpassed that of RelyX Unicem.
