Abstract Background: The optimal bonding of adhesives to dentin requires the sealer to be completely removed from dentinal walls. This study compared the efficacy of different sealer removal protocols on the microtensile bond strengths (MTBS) of single step adhesives to a calcium silicate-based bioceramic root canal sealer contaminated dentin. Methods: Standardized box-shaped Class I cavities were prepared in human lower third molars (N=50). All cavities were contaminated with a bioceramic root canal sealer (Endosequence BC Sealer, Brasseler, Savannah, USA), except the control group cavities. For the experimental groups, dentin surfaces were wiped with dry cotton pellets, cotton pellets saturated with water or rinsed with an air water syringe for 5 seconds, or applied aqueous ultrasonic scaler for 5 seconds prior to restoration procedure. All the cavity surface was restored with a one-bottle universal adhesive and composite resin. All the specimens were subjected to both thermocycling and mechanical loading. The restored specimens were sectioned into resin-dentin beams for mictotensile bond strength (Mtbs) evaluation. Additional specimens were prepared for scanning electron microscopy (SEM) to examination of dentin-adhesive interface (N=10).Results: The Mtbs for the 5 groups, the control, dry cotton, wet cotton, water rinse, and ultrasonic rinse group, were 13.42 ± 4.68, 11.96 ± 5.26, 13.03±6.07, 12.73±3.68, and 14.39±4.22 MPa, respectively. No significant difference was found between the mean bond strengths of the groups (p=0.725). In SEM examination no residual sealer was found in any group. Conclusions: Calcium silicate-based bioceramic sealer was removed from the dentin surface with all removal protocols when evaluated with Mtbs after thermal and mechanical cycle tests.

Abstract Aim The focus of this study was to examine the staining potential of calcium hydroxide (Ca(OH)2) on tooth structure following the removal of AH26 root canal sealer. Methods and Materials Fifty maxillary anterior teeth were prepared and obturated with AH26 and gutta percha. The sealers were then removed 24 hours later and the teeth were randomly divided into two groups. Ca(OH)2 was then placed in the root canals of the first group of teeth as a medicament and camphorated monochlorophenol (CMCP) was placed in the second group of teeth after the filling material was removed. The color of the external tooth surfaces was determined before tooth preparation and two weeks after the placement of the medicaments. The Z test was used for statistical analysis. Results All experimental teeth showed varying degrees of coronal discoloration with the Ca(OH)2 group showing more discoloration than the CMCP group (p<0.05). Conclusion Using Ca(OH)2 as a medicament after removing AH26 caused progressive discoloration of the teeth, whereas using CMCP caused only slight discoloration. Clinical Significance To avoid staining of the treated tooth, AH26 root canal sealer must be completely removed from the dentin walls before using a medicament.
