Abstract
Objective
To evaluate the impact of different surface pretreatments of cervical non-carious dentin on the bond strength to resin composite.
Data sources
In vitro studies that assessed the impact of pretreatment of cervical non-carious dentin on bond strength to resin composite were considered for inclusion. The protocol was conducted following PRISMA guidelines and registered in PROSPERO (CRD420251102471). Studies were identified after comprehensive online search in 5 different electronic databases including PubMed (Medline), Web of science, Scopus, Cochrane library, and Google scholar.
Results
Eight studies met the inclusion criteria. However, the results were inconsistent, with some studies reporting no significant differences or even inferior outcomes with pretreatments like ethylenediaminetetraacetic acid (EDTA) or sodium hypochlorite. Prolonged application of phosphoric acid (30–40 %, 15–90 s) and combined chemical-mechanical pretreatments (e.g., sandblasting with phosphoric acid) showed potential to improve bond strength compared to controls. Most studies exhibited a high risk of bias, primarily due to lack of blinding, inadequate sample size calculations, and failure to simulate clinical conditions.
Conclusion
Current scientific evidence suggests that pretreating cervical non-carious sclerotic dentin with prolonged application of 37 % phosphoric acid—either alone or in combination with mechanical roughening—may enhance bond strength to resin composite. However, the quality of the evidence is low. Further high-quality research, including studies on laser pretreatments and those simulating clinical conditions, is needed to establish reliable guidelines for clinical practice.
Clinical significance
Dentin of non-carious cervical lesion is physiologically different from normal dentin due to frequent and prolonged exposure to various oral conditions, such as thermal, chemical, and mechanical stimuli. Consequently, achieving reliable adhesion to this altered dentin substrate remains a clinical challenge. Therefore, surface pretreatment with prolonged application of 37 % phosphoric acid, either alone or in combination with mechanical roughening is recommended to increase the bond strength of resin composite to these lesions.
期刊介绍:
The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis.
Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research.
The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
