Comparative evaluation of wettability of AH plus, Ceraseal and Guttaflow bioseal root canal sealers on root canal dentin: An

Context: Effective root canal treatment relies on the ability of sealers to wet and penetrate the root canal system, ensuring a tight seal and preventing bacterial leakage. The current study investigates the wetting ability of newer root canal sealers by evaluating their contact angle. Aim: The objective of the present study was to evaluate and compare the wetting behavior of Guttaflow bioseal, Ceraseal, and AH plus root canal sealers. Materials and Methods: Decoronation and apical third resections of thirty extracted singlerooted human mandibular premolars were done. The roots were then split longitudinally into two halves buccolingually. The root dentin surfaces were treated using 10 mL 3% sodium hypochlorite for 5 min, 10 mL of 17% ethylenediaminetetraacetic acid for 5 min, and 2% chlorhexidine for 10 min. Then, these sixty dentin bars were randomly divided into three groups (n = 20): Group 1 - AH Plus, Group 2 - Ceraseal, and Group 3 - Guttaflow bioseal. The controlled volume of 0.1 mL sealer has been dispensed onto the dentin specimen using a micropipette. The contact angle of a drop of sealer was measured after 5 min using Ossila goniometer. Statistical Analysis Used: The data were analyzed using one-way analysis of variance and Tukey post hoc tests. The statistical significance was at Results: The mean contact angle values for AH Plus sealer were lower when compared to the other two sealer groups which is statistically highly significant. Conclusions: AH Plus showed lesser contact angle thereby better wettability than Ceraseal and Guttaflow bioseal on the root canal dentin surface.
