Comparative Analysis Of Sealing Ability Of Biodentin And Calcium Phosphate Cement Against Mineral Trioxide Aggregate (Mta) As A Furcal Perforation Repair Material (An In Vitro Study)

Dr.Tulsi Sanghavi*, Dr. Nimisha Shah**, Dr.Ruchi Rani Shah***.

Introduction: The ability of mineral trioxide aggregate (MTA),Biodentinand and Calcium phosphate cement to seal large furcation perforations were evaluated using a dye-extraction leakage method. Method: 30 extracted human mandibular first molars were divided into three experimental groups (n -10) according to the repair material used. Dye leakage was tested from an orthograde direction, and dye extraction was performed using full concentration nitric acid. Dye absorbance was measured at 550 nm using spectrophotometer. Result : ProRoot MTA (Maillfer, Dentsply) showed the least dye absorbance. Calcium phosphate showed the highest dye absorbance. and Biodentin came at intermediate level then other groups [Sanghvi T et al NJIRM 2013; 4(3) : 56-60]

Key words: Dye extraction, furcation perforation, MTA, Biodentin, Calcium phosphate
