Abstract

Mineral trioxide aggregate (MTA) has been shown to promote regeneration of the periodontal apparatus when used as a repair material in furcation perforations. Two variations of MTA (Gray and White) have been introduced to the dental market. The purpose of this study was to histologically compare the in vivo response to immediate furcation perforation repair using gray or white MTA in beagle dogs.

Under general anesthesia, non-surgical root canal therapy and furcal perforations were performed on sixteen mandibular premolars of eight 2-year old beagle dogs. The perforations were immediately repaired with either white (n=8) or gray (n=8) MTA. The animals were allowed to heal and were sacrificed five months later. Histological samples were prepared and evaluated histomorphometrically. The mean quantity of cementum formation in the two groups was measured and compared statistically using the Mann Whitney U-Test, at significance level α=0.05.

The results indicated that there was no statistically significant difference in the amount of cementum formation between the two groups (P=.878). Based on these results it appears that gray and white MTA are associated with a similar tissue reaction when used as an immediate furcal perforation repair material in beagle dogs.
