Dentine bonding agents are an important clinical contribution to modern composite technology. Important differences exist between the first- and second-generation materials which offer complementary advantages. The second-generation materials offer higher dentine bond strengths at the expense of greater chairside complexity. Indications for the use of both types of material are discussed. The role of smear layer and the primed layer is discussed and the connection is made between bond mechanism and clinical techniques. The clinical criteria, such as retention, microleakage and tooth strengthening, are related to the role of the hard tissue bond.

The effect of different adhesive strategies and diamond burs on dentin bond strength of universal resin cements.
Clin Oral Investig
January 2025
Department of Restorative Dentistry, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan.
Objectives: To evaluate the shear bond strength (SBS) of universal cements (UCs) to dentin prepared with different diamond burs using various adhesive strategies.
Materials And Methods: One-hundred-twenty molars were prepared to expose the mid-coronal dentin. The teeth were divided into two groups according to diamond bur preparations: coarse and super-fine grit burs.

Purpose: This study aimed to investigate the effect of chlorhexidine (CHX) cavity disinfectant on interfacial microleakage and micro-tensile bond strength (μTBS) of a universal adhesive bonded to dentin in both self-etch (SE) and etch-and-rinse (ER) modes.
Methods: Class I cavities were prepared in the coronal dentin of extracted human teeth and assigned to two etching modes (SE or ER), then subdivided by disinfection with or without CHX (n = 5). Cavities were restored using Single Bond Universal Adhesive and Filtek Z350 XT composite.

This study investigated the effects of resin composites (RCs) containing surface pre-reacted glass ionomer (S-PRG) filler on the dentin microtensile bond strength (μTBS) of HEMA-free and HEMA-containing universal adhesives (UAs). Water sorption (WS) and solubility (SL), degree of conversion (DC), and ion release were measured. The UAs BeautiBond Xtreme (BBX; 0% HEMA), Modified Adhesive-1 (E-BBX1; 5% HEMA), Modified Adhesive-2 (E-BBX2; 10% HEMA), and two 2-step self-etch adhesives (2-SEAs): FL-BOND II (FBII; with S-PRG filler) and silica-containing adhesive (E-FBII) were used.

The cross-linking reagent has been proposed as a means of modifying dentin collagen, inhibiting matrix metalloproteinase activities, and enhancing bond durability during dentin bonding procedures. This study aimed to synthesize an operation-friendly dual cross-linking reagent-3-(4-formyphenoxy)-2-hydroxypropyl methacrylate (FPA)-to assess its ability to cross-link dentin collagen and reduce enzymatic activity at the bonding interface. Cytotoxicity was evaluated by a cell counting kit-8 test and calcein AM/propidium iodide assay.

Objective: The purpose of this study was to examine the effect of several antiseptic mouthwashes on the dentin microtensile bond strength of self-etch adhesive, considering the influence of rinsing with water.
Methods: Forty flat dentin surfaces were produced by sectioning sound extracted third molars. They were randomly divided into four main groups: (1) artificial saliva (control); (2) 1 % hydrogen peroxide; (3) 0.
