Invitro comparison of ProRoot MTA and Root MTA micro leakage in repairing of furca perforation in primary teeth

Perforation is one of the most important causes of failure of endodontics treatment. Several materials have been proposed for a non surgical repair of furcal perforation and MTA is one of them. The aim of this study was to evaluate repairing of furcal perforation of primary molars with Root MTA and ProRoot MTA. This in vitro study was conducted on 54 teeth that were randomly divided into four groups: Root MTA (n=24), Pro Root MTA (n=24), positive and negative controls (n=6). After preparation of access cavity, perforations were made and the perforation areas were repaired with Root MTA and ProRoot MTA.After staining and preparation of mesiodistel longitudinal section, die leakage was measured with stereomicroscope. The data was analyzed with Mann Whitney test. P<0.05 was considered as significant level. The data showed that ability of sealing of Root MTA is more than Root MTA. Based on the results of this study Root MTA is not a suitable substitute for ProRoot in repairing of furcal perforation of primary molars.
