“…However, the divergent outcomes have demonstrated that so far no ideal sealing material has been achieved, i.e., a material that may provide optimal sealing, easy manipulation, biocompatibility, and ability of induction of osteogenesis and cementogenesis. 15 The favorable chemical and biological properties of MTA have changed this scenario. 16 But MTA has certain drawbacks such as long setting time, poor handling, and relatively high price.…”

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.

“…While in contrast Broon et al ., 2006[ 55 ] reported that white Portland cement(WPC) and MTA-Angelus(grey MTA) showed more teeth inflammation than the ProRoot MTA (white MTA) when all of them used to evaluate the response of interradicular periodontal tissues of dogs’ teeth with root perforations. Morais et al ., 2006[ 56 ] reported no differences in inflammatory response and biocompatibility between ProRoot MTA(white MTA) and Portland cement that mixed with iodoform for suitable radiopacity when both of them were implanted in rats’ tissues used for the experiment.…”

There were several materials used to seal different types of perforation defects. MTA is one of these restorative materials that is considered the most effective, biocompatible, non-toxic, and non-irritant; promote bone healing and cementum regeneration. The objective of this article was to review and summarize the sealing ability of MTA compared with the other materials used for sealing different types of root perforations of permanent teeth. A literature search was conducted using Medline, accessed via the National Library of Medicine Pub Med from 2005 to 2015 searching for articles related to sealing ability of MTA. This study found that factors affecting prognosis are the size, site of the perforation and time elapsed as well as the repair material. MTA is an important filling material to be used for sealing different types of perforations when perforated sites sealed immediately with MTA.

Background:Mineral trioxide aggregate (MTA) has a high biocompatibility and its physical properties could be improved by adding the containing silica fume an amorphous silicon dioxide (condensed silica fume [CSF]). The aim of this study was to evaluate the cytotoxicity of MTA mixed with CSF on the viability of L929 mouse fibroblast cell using 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide reduction assay (MTT assay).Materials and Methods:In this in vitro study white MTA was mixed with distilled water according to the manufacturer's instructions. Mixtures of White MTA with 10%, 15%, and 20% CSF by weight were prepared and mixed with distilled water. Cytotoxicity of mixtures was compared with MTT assay on L929 mouse fibroblast cell line after 24, 48, and 72 h. Differences in cytotoxicity were assessed by one-way analysis of variance (ANOVA).Results:Mean ± SD of vital cell counts cultured in MTA, MTA + 10% CSF, MTA + 15% CSF, and MTA + 20% CSF were 98% ± 6%, 97% ± 6%, 94% ± 4%, and 98% ± 4%, respectively. One-way ANOVA did not reveal any statistically significant difference between the groups (P > 0.05).Conclusion:It may be concluded that addition of CSF to MTA may not influence its cytotoxicity.
