Sealing Ability of MTA vs Portland Cement in the Repair of Furcal Perforations of Primary Molars: A Dye Extraction Leakage Model—An In Vitro 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 (n = 20) in which perforations were repaired with MTA (ProRoot MTA, MTA-Angelus), group II (n = 20) in which perforations were repaired with the Portland cement, group III (n = 10) in which perforations were left unsealed (positive control), and group IV (n = 10) without perforations (negative control). All samples were subjected to 1% of basic fuchsin dye challenge followed by dye extraction with 65 wt% of nitric acid. Samples were analyzed using the automatic microplate spectrophotometer 545 nm and the readings were statistically analyzed. RESULTS: There was no statistically significant difference in the microleakage between MTA and Portland cement repair groups. CONCLUSION: Portland cement provides an effective seal for primary teeth furcal perforations and can be considered a more economic substitute for MTA as a repair material enhancing the prognosis of perforated primary teeth that would otherwise be extracted.
