Abstract

Introduction: The current study aimed to discuss the efficacy of mineral trioxide aggregate (MTA) in direct pulp capping (DPC) in terms of the histological effect after mechanical pulp exposure of immature premolars of Mongrel dogs

Methods: For histological analysis, a spilt-mouth design was used in which 24 immature

premolars of three healthy 2-3 years-old Mongrel dogs were mechanically exposed and

capped with MTA. After 3 months, animals were sacrificed, and stained specimens (hematoxylin and eosin) were examined for inflammatory cell reactions and hard tissue formation Chisquare

and Fisher’s exact tests were used to compare the histological success rates

Results: Histologically, MTA material showed no inflammatory cells after 3 months, while hard

tissue was significantly superior in the MTA.

Conclusions: MTA is a biocompatible material with a favorable pulp tissue response in

terms of the absence of an inflammatory cell reaction a small amount of calcified tissue

formation after 3 months. MTA is an effective treatment option in the DPC of carious, immature permanent teeth.
