Abstract:

Attainment of ideal root canal treatment comprises of various essential factors such as proper instrumentation, biomechanical preparation, obturation and ultimately depending upon post-endodontic restoration. The main objective of the treatment is to get absolute rid of the microbial entity and prevent any future predilection of re-infection. In order to achieve that, a proper seal is required to cut down any chance of proliferation of bacteria and future occurrence of any pathology. Guttapercha is the most extensively used central core material to fill the radicular space. Using this material alone cannot produce and ensure a tight seal of the root canal system as it doesn???t bond with dentine wall. Hence, gutta-percha is used in combination with the root canal sealer to provide a fluid-tight seal. An ideal root canal sealer should be capable of creating an effective bond between the core material and the dentine of the root canal to prevent the leakage. To provide an effective seal, several types of endodontic sealers have been developed and the evaluation of the apical sealing ability of these materials is extremely important. To our knowledge, there are no reports of studies that have evaluated the adhesive force between the endodontic sealers and treated dentine. The present study evaluated the adhesive force of three different root canal sealers to root canal dentine using atomic force microscope. The results of the study showed a very strong evidence that there exists a statistically significant difference among all the experimental groups (p<0.05). Group I (AH Plus) exhibited a significantly greater adhesion force values than Group II (iRoot SP) and Group III (MTA Fillapex). Group III (MTA Fillapex) was found to have the least adhesion force values among all the groups. A significant difference was also observed with a pair-wise comparison of all the tested groups (p<0.05). Thus, it can be concluded that AH Plus root canal sealer shows greater adhesion capacity followed by iRoot SP and MTA Fillapex.
