Abstract

Background and aim: The application of DENTIN BONDING agents in operative dentistry, has led to numerouse advantages such as microleakage reduction. The goal of this study was to clarify the possible effects of DENTIN BONDING agents on dental pulps, in contact with dentinal extended surfaces. Materials and Methods: In this experimental study, 72 restorations were made on the anterior teeth of six adult dogs: Restorations were divided into four groups.Group 1: Small CIV cavities restored directly with composite and denin bonding agent. Group 2: Large cavities (prepared for full coverage crown) restored indirectly composite and DENTIN BONDING agent.Group 3: Large cavities (prepared for full coverage crown) restored with composite and cemented polycarboxylate cement indirectly.Group 4: Large cavities restored with composite crowns and cemented with resin cement along with DENTIN BONDING agent. After 7,25 and 60 days animals were killed and histopathological studies were made on their pulp tissues. Data were subjected to one-way ANOV A, Kruska-Walis, Mann-Whitney and U-Wilcoxon tests.Results: There were significant differences between groups 1 and 2, groups 2 and 4, groups 1 and 4 and groups 3 and 4 (p<0.05). Generally, the most irritation was observed in group 4 and groups 2, 3 and 1, respectively. In group 1, a slight inflammation was found after 7 days that decreased or totally eliminated in 25 and 60 days. In group 2, all inflammatory markers were more then group 1 and some of then remained after 60 days. The inflammafory markers, in group 3, were more than group 1 and considerably less than group 2 and decreased in 25 and 60 days. In group 4, all markers in all periods, were more than other groups, with its peak after 60 days.Conclusion: It seams that DENTIN BONDING agents put irritative effects on dental pulp. If other factors such as previous irritations, or those associated with cavity preparation methods or extensive surface contacts were present, more or even irreversible changes could be made in dental pulps.
