Sealing Ability of MTA vs Portland Cement in the Repair of Furcal Perforations of Primary Molars: A Dye Extraction Leakage Model-An Study.

Aim: The purpose of this present study is to compare the ability of MTA and Portland cement to seal furcal perforations in extracted primary molars using the dye extraction leakage model.

Materials And Methods: Sixty primary molars were selected and randomly divided into four groups after access openings and furcal perforations were created in the pulp chamber floor. Group I ( = 20) in which perforations were repaired with MTA (ProRoot MTA, MTA-Angelus), group II ( = 20) in which perforations were repaired with the Portland cement, group III ( = 10) in which perforations were left unsealed (positive control), and group IV ( = 10) without perforations (negative control).
