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

Abstract

AimThe 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 methodsSixty 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.ResultsThere was no statistically significant difference in the microleakage between MTA and Portland cement repair groups.ConclusionPortland 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.How to cite this articleReddy NV, Srujana P, et al.

“…A limitation of the current study is that the use of an in vitro model may not completely recapitulate the exact clinical situation. Several recent studies from 2019-2021 [52][53][54] attempted to compare the sealing ability of different bioceramic materials, but these used dye extraction [52,53] or protein leakage [54] models without any added bacterial contamination. Further in vivo studies will be needed to assess the antibacterial activity of various calcium silicate-based materials in more detail.…”

“…Hence, apical leakage or sealing ability of a root sealer should be evaluated to assess its potential effectiveness if it is designed to be applied clinically. 41 Different in vitro sealing ability tests have been reported in the literature. Methods such as bacterial penetration, isotopes, and electromechanical means could serve as the qualitative assessment of sealing ability.…”

“…Complete dissolution of teeth guarantees release and extraction of all dye including that penetrating unsealed irregularities, the deepest and smallest dentinal tubules. 30,33,41,42 The dye-extraction method is found to be a reliable, simple, widely used passive technique for volumetric determination of sealing ability. 42,43 The capillarity principle is of great significance in the dye-extraction method for assessing apical leakage.…”
