Comparative Evaluation of the Efficacy of Three Different Dental Materials in Sealing Furcation Perforation" -an in-Vitro Study

Aim- To compare the sealing ability of Biodentin ,MTA Angelus, and GIC to repair furcation perforation when used with and without an internal matrix ( collagen) | Materials and Methodology : Eighty extracted human mandibular first molars were divided into two control groups (n=10),and three experimental groups (n=20) ac- cording to the repair material used i.e Biodentine, MTA- Angelus and GIC . Each experimental group was divided into two subgroups (n=10) according to whether internal matrix was used or not before perforation repair. The efficacy f repair material was assess using dye extraction method using absorption spectrophotometer | Results: Biodentin with interal matrix (0.109) and MTA-Angelus(0.115) with internal matrix showed least dye leakage .GIC with(0.18)and without internal matrix(0.19) showed most dye absorbance . Biodentin (0.134) and MTA -Angelus (0.144) showed intermediate dye absorbance . | Conclusion :Collagen as internal matrix membrane improves the sealing ability of MTA and BIO- DENTIN which also have better perforation sealing ability than GIC
