Long-term microtensile bond strength of universal adhesives with human dentin: a mini review
E. Koytchev
Abstract: Objectives: This mini review aimed at evaluating the long-term bonding effectiveness of universal dental adhesives (UA) with human dentin.
Methods: The web databases of PubMed and Web of Science from were scanned using the keywords: (universal adhesives, long-term microtensile bond strength - µTBS, human dentin). After following the inclusion criteria, a total of 16 articles were retained for the purposes of this review.
Results: Overall, the different articles investigated various factors and their influence on the µTBS. The main variables included: dentin moisture levels, etching times and modes, inclusion of antibacterials and dentin crosslinkers, air-blowing and bond application times. The majority of studies were consistent in their findings that a long-term stable bond is achievable by using the adhesives in self-etching protocol. Dentin cross-linkers were beneficial to improve the longevity of UA systems. The effects of antibacterials and water storage times, as well as air blowing were material dependent.
Conclusions: Generally, although with well-studied short-time µTBS performance, the UAs need further clinical and in vivo validation studies to evaluate bond strength over time.
