Sealing Ability of MTA Used in Perforation Repair of Permanent Teeth; Literature Review

Abstract

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.

Bio-Inductive Materials in Direct and Indirect Pulp Capping—A Review Article

“…MTA has proven to induce mineralization beneath exposed pulp and have the potential of maintaining pulp vitality. Hence, the indications for the use of MTA have expanded considerably from its original use, and it has recently became a superior substitute for Ca(OH) 2 in many other clinical applications, including direct [14,15,30,31] and indirect pulp capping, perforation repairs in roots or in furcations [32] and the apexification procedure [33][34][35]. The powder of MTA is a mixture of a purified Portland cement and bismuth oxide to provide radiopacity.…”

Calcium Silicate Cements Application in Lateral Root Perforation Repair: A Case Report with 16-Month Follow-Up

“…Mineral Trioxide Aggregate (MTA), has been introduced to seal communications between the tooth and the external surfaces, [16] showing very good outcomes due to hydrophilic characteristics. Currently, is used due to multiple applications in endodontics: antimicrobial activity, root canal sealer, dimensional stability, non-toxic, and promotion of osteogenesis and cementogenesis [17]. However, the adhesive strength between MTA and dentin is still a disadvantage since MTA demand at least 3 -4 mm to prevent microleakage.…”

Comparison of Sealing Ability of Experimental Tricalcium phosphate cement versus Biodentin and Mineral Trioxide Aggregate used for Furcation Perforation Repair

“…Statistical analysis showed that the sealing ability of Biodentine was best among the three materials whereas sealing ability of the experimental tricalcium phosphate was similar to the MTA as perforation repair material. MTA encounters some problems during its clinical use, like; unease of handling, long setting time and liability to discolor the tooth (18) .…”
