Análise da capacidade seladora dos cimentos de Portland e agregado de trióxido mineral em perfurações de furca de molares

Abstract

Objective: To analyze the sealing ability of Mineral Trioxide Aggregate (MTA) and Portland Cement (PC) in furcation perforations of human molars through three techniques. Methods: Ninety upper and lower extracted human molars with formed roots and not fused were selected. Perforations were performed on the floors of pulpal chambers by means of spherical burs. Specimens were randomly divided into two experimental groups of forty-five teeth each, using PC for Group I and white MTA for Group II. Group I was divided into 3 subgroups, called IA, IB, IC with fifteen samples each. Group II was also divided into 3 subgroups, called IIA, IIB, IIC with fifteen samples each. The checks of infiltration were carried out through a stereoscope with 5X magnification. The Kruskall-Wallis and Mann-Whitney tests were used for statistical analysis. Results: The use of MTA and PC inserted by three different techniques did not prevent the occurrence of leakage into furcation of extracted human molars. It is also clear that the CP accommodated in furcation perforations through ultrasound had better performance. Conclusion: Further studies should be carried out to improve the performance of the sealing material for application in critical dental regions.

Comparison of Mineral Trioxide Aggregate, Endosequence Root Repair Material, and Biodentine Used for Repairing Root Perforations: A Systematic Review

“…These studies investigated the use of MTA, EndoSequence ERRM and Biodentine in the root perforation that happened during the endodontic treatment on human and animal studies. All the studies included in this systematic review were eleven In-vitro studies 8,10,12,13,20,26,[28][29][30][31][32] , two In-vivo studies 2,17 , one Randomized controlled trial study (RCT) 33 , four Retrospective clinical studies 18,[34][35][36] , and four Case reports. 1,7,9,37 In regard to the types of root repair materials performed, fourteen studies were performed with MTA in a combination of other root repair materials such as ERRM and Biodentine.…”

“…1,7,9,37 In regard to the types of root repair materials performed, fourteen studies were performed with MTA in a combination of other root repair materials such as ERRM and Biodentine. 2,8,10,12,13,17,20,26,[28][29][30][31][32]35 The placement of Biodentine alone as a root repair material for root perforation was made in three studies. 1,7,18 On the other hand, five studies, MTA has placed alone.…”

“…29 In another study done in 2017, they noticed that the MTA displayed better sealing in comparison to Biodentine. 2 Also, an in-vitro study conducted by Bampa, et al 31 in 2015, they assessed the MTA ability to seal using three different insertion techniques. The study enabled the observation that irrespective of the technique used it was not possible to prevent the infiltration.…”

“…The study enabled the observation that irrespective of the technique used it was not possible to prevent the infiltration. 31 That way, they settled the requirement for more studies to be performing in order to enhance the materials sealing property in critical dental spots. 31 One study done in 2014, when comparing the sealing capacity between the Biodentine and Endosequence ERRM noticed that the Endosequence ERRM had better performance.…”
