Evaluation of the Effect of Anti-COVID-19 Mouthwashes on Shear Bond Strength of Composite Resin Restorations to Dentin and Enamel: An “In Vitro Study”

Table 1

. Summary of the procedures.

Group		Procedure steps
A	Dentin exposure; Immersion in 15 ml 0.07% cetylpyridinium chloride mouthwash for 1 minute	Drying the tooth, scrubbing the primer on the dentin surface for 15 seconds and removing the solvent, placing the bond on the dentin surface and thinning and curing it for 20 seconds, placing the resin composite cylinder on the dentin, and curing it for 20 seconds from the mesial and distal side, respectively
B	Dentin exposure; Immersion in 15 ml 1% povidone-iodine mouthwash for 30 seconds
C	Dentin exposure; Immersion in 15 ml 1% hydrogen peroxide mouthwash for 1 minute	Removing the buccal surface enamel, drying the tooth, etching the enamel surface with phosphoric acid for 20 seconds, rinsing with water for 20 seconds, rinsing with water and air mixture for 20 seconds, drying with air for 20 seconds, scrubbing the bond on the enamel surface, thinning and curing it for 20 seconds, placing the resin composite cylinder on the enamel, and curing it for 20 seconds from the mesial and distal side, respectively
D	Dentin exposure; Immersion in 15 ml 0.2% chlorhexidine mouthwash for 1 minute
E	Dentin exposure; Immersion in 15 ml distilled water for 1 minute
