Comparative evaluation of chlorhexidine and benzalkonium chloride pretreatments on bond strength durability of immediate dentin sealing with universal adhesive: an in vitro study.

ABSTRACT:

Background

Effective and durable bonding of immediate dentin sealing (IDS) is a crucial factor in the success of adhesive-bonded restorations. This study aimed to investigate the influence of chlorhexidine (CHX) and benzalkonium chloride (BAC) pretreatments on the immediate and aged bond strengths of a universal adhesive used in IDS across two etching modes.

Methods

Flat dentin surfaces were obtained from 120 molars and divided into six groups based on pretreatments (no treatment, CHX, and BAC) in two etching modes (etch-and-rinse (E&R) and self-etch (SE)) using All Bond Universal, in conjunction with a hydrophobic resin layer. Following the provisional stage and resin cementation, immediate and aged shear bond strengths (SBS) were measured after 24 h and 1 year of storage,
