Adhesion of Root Canal Sealers to Dentin after Dentin Pre-treatment- An In-Vitro Study

Adhesion of Root Canal Sealers to Dentin after Dentin Pre-treatment

Abstract

Aim & Objective: Comparatively evaluate the effect of dentin pre-treatment on adhesion of various root canal sealers. Materials & Method: Single rooted human permanent teeth with single canal (n=136) were prepared using step back technique. They were divided randomly into four experimental Groups (n=34) according to the irrigant used (Group A- Smear Clear, Group B -17% EDTA, Group C -30% Citric Acid & Group D - Normal Saline). Two specimens from each group were examined under SEM. Each group was further subdivided in to four subgroups (N=8) according to the root canal sealer applied (Endomethasone, Roekoseal, Acroseal and AH Plus). Teeth were obturated using lateral condensation technique. Microleakage was evaluated by linear dye penetration study. Results:30% Citric Acid as a root canal irrigant was most effective in smear layer removal followed by Smear Clear and 17% EDTA. Endomethasone showed the maximum leakage while Roekoseal showed the minimum leakage with Smear Clear and Normal Saline (p<0.05). Acroseal showed maximum microleakage while AH Plus showed minimum with 17% EDTA (p<0.05). With 30% Citric Acid, Acroseal had the maximum value and Roekoseal had the minimum value (p>0.3). Conclusion: In all the combinations AH Plus in 17% EDTA (Group B) had the minimum leakage while Endomethasone-N had the maximum leakage with Normal Saline (Group D)..
