Abstract

Objective: To evaluate the smear layer removal and wettability of AH Plus sealer on root canal dentin treated with MA (maleic acid), MAþCTR (cetrimide) and MAþCTRþCHX (chlorhexidine) as final irrigating regimens.Material and methods: For smear layer removal, 40 teeth were instrumented to size F4 and divided into four groups: (1) 7% MA, (2) 7% MAþ0.2% CTR, (3) 7% MAþ0.2% CTRþ2% CHX, (4) distilled water (control). After irrigation, teeth were subjected to SEM analysis. For contact angle analysis, 20 teeth were split longitudinally and divided into four groups similar to smear layer analysis. AH plus sealer was placed on each specimen and contact angle was analysed.Results: In both smear layer (p¼.393) and contact angle analysis (p¼.961), there was no significant difference between the groups MA and MAþCTR. However, MAþCTRþCHX removed smear layer less effectively (p¼.023) and increased the contact angle of the sealer (p¼.005). In smear layer analysis,specimens in negative control group were heavily smeared. In case of contact angle analysis, samples in the control group had least contact angle.Conclusion: MA alone or in combination with CTR removed smear layer effectively and increased the wettability of AH plus sealer to root canal dentin.
