Article Synopsis
- The research aimed to investigate urushiol as a cross-linking agent to help remineralize etched dentin and prevent collagen breakdown, with the goal of enhancing bond strength at the resin-dentin interface.
- Urushiol primers were prepared in different concentrations and applied to acid-etched dentin samples, which were then analyzed for changes in mineral content and mechanical properties using various advanced techniques.
- Results showed that the 0.7% ethanol urushiol primer significantly improved dentin remineralization, bond strength, and reduced the activity of harmful enzymes, indicating its potential effectiveness in dental applications.
Article Synopsis
- The study addresses the low durability of composite resin restorations caused by weak resin dentin bonding due to hydrophilic components in adhesives, which lead to issues like water absorption and reduced bond strength.
- Researchers developed a new hydrophobic dentin adhesive by replacing part of a common resin component with a light-curable urushiol monomer, thoroughly testing its properties against a standard adhesive.
- Results show that the new adhesive, with 20% urushiol, demonstrated enhanced hydrophobicity, low cytotoxicity, strong mechanical properties, and improved bonding strength, indicating its potential for better restoration durability.
Objectives: To evaluate the effects of Nd:YAG laser irradiation on the microstructures of dentin surfaces and the long-term bond strength of dentin under simulated pulpal pressure.
Materials And Methods: Under simulated pulp pressure, 30 freshly extracted caries-free third molars were cut into 2-mm-thick dentin samples and then divided into five groups: the control and laser groups (93.3 J/cm; 124.
Effect of collagen cross-linkers on dentin bond strength: A systematic review and network meta-analysis.
Front Bioeng Biotechnol
January 2023
This study aimed to evaluate the role of collagen cross-linkers in the bonding performance of the resin-dentin interface through a systematic review and a network meta-analysis. The literature search was conducted in several databases like PubMed, EMBASE, Cochrane, Scopus and Web of Science from their inception till 30 April 2022. The inclusion criteria consisted of studies evaluating the micro-tensile and micro-shear bond strengths of different cross-linkers acting on dentin.

The effect of laser etching dentin on the bonding strength of composite resin reported in the literature is still inconclusive. The purpose of this review was to evaluate whether laser etching can improve the immediate and long-term bonding strength of dentin and investigate the effect of different types of adhesives on the bonding strength of dentin.
