Impact of antimicrobial photodynamic therapy on micro-shear bond strength to dentin.
To evaluate in vitro the bond strength through the micro-shear test of two adhesive systems (self-etching and total-etch), on bovine dentin surfaces after aPDT. For the aPDT, 0.01% methylene blue and two different light sources (red laser and LED) were used.Sixty samples were randomly divided into 6 groups (n = 10) for the micro-shear test: G1: self-etching adhesive (USB) without aPDT, G2: aPDT (laser) + USB, G3: aPDT (LED) + USB; G4: total-etch adhesive (ASB) without aPDT; G5: aPDT (laser) + ASB, G6: aPDT (LED) + ASB), followed by analysis of the fracture patterns of the samples. For statistical analysis, a two-way ANOVA (adhesive and treatment) and Tukey's test were performed, adopting a significance level of 5%.Regarding bond strength, there was no significant difference between the 6 groups analyzed. An adhesive fracture pattern predominated.Based on the results and the irradiation parameters used in this study, no changes in the bond strength of the resin to healthy dentin were observed after treatment with aPDT.
期刊介绍：
Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics.
The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
