Histological and histomorphometrical evaluation of furcation perforations filled with MTA, CPM and ZOE

Abstract

The periodontium adjacent to perforations filled with MTA and CPM exhibited clear evidence of re-establishment and thus better biocompatibility than ZOE.

Heavy Metal Analysis of Ortho MTA and ProRoot MTA

“…In other words, we made 5 samples of ProRoot MTA and another 5 samples for Ortho MTA for heavy metal analysis, whereas in previous studies the experiment was performed with only 3 replicates (20,37). Considering that the increasing sample size could reduce the risk of incorporating bias into the data, our results could be considered to give more solid evidence than in previous studies (12)(13)(14)(15)(16)(17).…”

“…In addition, there are studies that reported the sealing ability or biocompatibility of MTA as endodontic sealers (8)(9)(10)(11)(12)(13)(14). Furthermore, as was suggested in the recent review article by Parirokh and Torabinejad (1), various biomaterials with biological activities similar to those of MTA, such as Bioaggregate (Innovative Bioceramix, Vancouver, BC, Canada) (15) and MTA Angelus (Angelus, Londrina, PR, Brazil) (16), have been introduced and have shown good biocompatibilities and sealing abilities.…”

Properties of Hydrated Mineral Trioxide Aggregate

“…The periodontium adjacent to perforations fi lled with MTA and Endo CPM Sealer exhibited clear evidence of reestablishment and thus demonstrated better biocompatibility than zinc oxide-eugenol ( Fig. 3.4 ) [ 51 ]. Contaminations of lateral perforations can impair the healing process.…”

Hydroxyl and calcium ions have also been shown to release from this cement similar to MTA, and therefore, they may act as an alternative root-end fi lling material [ 160 ].…”
