Evaluation of Microleakage of Premixed Bioceramics and Bio MTA as Furcal Perforation Repair Materials in Primary Teeth

Abstract

Purpose:The aim of this in vitro study was to evaluate the microleakage of premixed BioCeramics (BCs) and mineral trioxide aggregate (MTA) for sealing primary molar furcal perforations. Materials and Methods: This study was carried out on 30 extracted mandibular primary molars. Perforations of the furcation areas were created in the pulp chamber floor of the teeth. The molars were then divided randomly in two groups (n=15). Perforations were then repaired with biocompatible materials. After 72 h, the teeth were immersed in 2% basic fuchsine dye solution for 24h. The teeth were then sectioned longitudinally and evaluated for dye leakage. Data analyzed statistically using ANOVA test. Results: There was a statistically significant difference between the micro leakage of MTA (1669.25±140.59 µm) and premixed Bioceramics(1275.21±235.998 µm) groups (P>0.008). Conclusion: Premixed Bioceramics appeared to have superior sealing ability than MTA in perforation repair in primary teeth.An ideal sealing material should be biocompatible, non-toxic, bactericidal or bacteriostatic, radiopaque, non-absorbent, and maintain a good seal. Moreover, it should possess the ability to induce osteogenesis Codex : 01/22.04
