THE LATEST ADHESIVE TECHNOLOGIES IN DENTISTRY

Abstract

Over the past decade, adhesive dentistry has undergone a fundamental transformation, shifting from complex
multi-step procedures to highly efficient and simplified techniques. The durability of the resin–dentin interface, considered
the weakest link in restorative dentistry, plays a critical role in the long-term success of composite restorations and indirect
prosthetic treatments. This study focuses on recent advances in dental adhesive technologies, with particular emphasis
on eighth-generation universal adhesives, bioactive bonding agents, and the chemical integration of functional monomers
such as 10-MDP. Previous clinical trials and laboratory studies were comprehensively reviewed to evaluate hybrid layer
durability, technique sensitivity, and bond strength. The study compares total-etch, self-etch, and selective-etch modes
implemented through modern universal adhesive systems. The introduction of 10-MDP (10-methacryloyloxydecyl
dihydrogen phosphate) has become the “gold standard” for providing chemical adhesion to dental tissues as well as
restorative materials such as zirconium dioxide and non-precious alloys. In addition, the “No-Wait” application technique
significantly reduces technique sensitivity by enabling immediate penetration into dentinal tubules without prolonged
rubbing. Recent developments in bioactive adhesives have demonstrated promising results in inhibiting matrix
metalloproteinases (MMPs), thereby preventing enzymatic degradation of collagen fibers and breakdown of the hybrid
layer. Modern adhesive technologies not only simplify clinical workflows but also effectively enhance bond durability.
Universal adhesives offer clinicians greater flexibility without compromising fixation strength. Future prospects include
the widespread use of biomimetic materials capable of stimulating secondary dentin formation and providing long-term
antimicrobial protection at restoration margins
