Sealing Ability of Injectable Dental Composites, Biodentine and MTA in Repairing Furcal Perforation of Permanent Molar Teeth.

Furcal perforation is one of the most common undesired complications during dental treatment. It requires immediate seal to ensure the prognosis of the involved tooth. The aim of this study is to compare the sealing ability of injectable dental composites, namely G-aenial Universal Flo (GAUF) and Paracore with Biodentine and Mineral Trioxide Aggregate (MTA) as furcal perforation materials. This study was conducted on 68 extracted teeth. Upon decoronation of the tooth 4mm above cementoenamel junction, endodontic access cavity was done followed by the creation of furcal perforation in the pulp chamber floor. The teeth were assigned randomly into four experimental and two control groups. These perforations were then repaired with the intended materials. The teeth were submerged in 2% basic fuchsin for 24 hours then sectioned and evaluated for dye leakage. The data were analysed using Median's Test and Mann Whitney U Test. One specimen for each test group were inspected under scanning electron microscope (SEM). The results showed that the percentage of dye penetrations were significantly lower in Paracore and GAUF compared to Biodentine and MTA groups (p<0.001). Paracore demonstrated less gap at material tooth interface under SEM. Both Paracore and GAUF sealed furcal perforation better than Biodentine and MTA. [ABSTRACT FROM AUTHOR]
