AN EVALUATION OF FURCAL PERFORATION REPAIR USING MINERAL TRIOXIDE AGGREGATE AND RESIN MODIFIED GLASS IONOMER CEMENT WITH AND WITHOUT THE USE OF OPERATING MICROSCOPE- AN IN VITRO STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 49
Abstract
BACKGROUND This study evaluated in vitro the effect of using the operating microscope on repairing furcation perforations using resin modified glass ionomer cement or mineral trioxide aggregate. MATERIALS AND METHODS In this in-vitro study, forty-six extracted, human, permanent molar teeth with divergent roots and intact furcation area were used. They are sound or minimally restored. The teeth were divided randomly into four groups having 10 samples in each group. Using an ISO 012 round bur for furcal perforation were created in the teeth with in a slow-speed hand piece. Different materials were used in different group to repair perforation, with and without the use of the operating microscope. Two control groups- positive control and negative control, having 3 samples in each group were included in the study. In 100% humidity, all groups of teeth were stored, and the repair materials were allowed to set and mature for 72 hrs. at room temperature and they were assessed for the quality of placement under X26 magnification. Using India ink for testing of leakage at the repair site, the teeth were then demineralized, dehydrated in alcohol, and made transparent in methyl salicylate. Then at X26 magnification dye penetration into the furcation repair was evaluated. RESULTS Perforations that were repaired with mineral trioxide aggregate significantly leaked less dye than resin modified glass ionomer cement (p<0.001). There was no significant difference in the quality of perforation repair with either material whether the operating microscope was used or not. Therefore, it can be inferred that quality of furcal repair can be better obtained with mineral trioxide aggregate when compared with resin modified glass ionomer cement. The use of operating microscope does not make any difference with the outcome of furcal perforation repair. CONCLUSION In this in vitro study, the furcal perforations repaired with mineral trioxide aggregate showed significantly leak-less dye penetration than those repaired with resin modified glass ionomer cement (p < 0.001). Quality of furcal repair can be better obtained with MTA than RMGIC. The use of operating microscope (OM) makes no difference with the outcome of furcal repair.
