“…Previously done studies have proved that the treatment with laser results in an anfractuous surface (fractured and uneven) which leads to better bonding of cement. [ 21 22 23 ] SEM evaluation of representative specimens of Er:YAG laser-irradiated dentin in this study also demonstrated the complete removal of smear layer and opened dentinal tubules orifices. Similar findings were also observed in the study carried out by Hossain et al [ 24 ]…”

Aim and Objectives: The purpose of this study was to investigate the effect of dentin surface treatment with aluminum oxide air abrasion and Er:YAG laser on tensile bond strength of metal crowns. Metal crowns were luted with conventional glass ionomer cement (GIC) in the teeth with reduced crown height, where preparation geometry did not provide optimal retention form. Materials and Methods: Forty-eight human premolars were prepared to receive metal crowns and were randomly divided into four groups for tensile bond strength testing. Group A: Untreated dentin luted with self-adhesive composite resin cement as positive control; Group B: Untreated dentin luted with GIC as negative control; Group C: Surface treatment with 50 μm aluminum oxide air abrasion and luted with GIC; Group D: Surface treatment with Er:YAG laser (λ =2.94 mm) with a total energy 84.88 J/cm 2 of (60 mJ/pulse, 10 Hz, 60 pulses, and 100 μs pulse width) and luted with GIC. The cemented specimens were thermocycled and later subjected to axial load in a universal testing machine at 0.5 mm/min cross-head speed for tensile testing. Scanning electron microscopic evaluation of dentin surface treatment and cement–dentin interface was also done in representative specimens. Results: One-way analysis of variance showed statistically significant difference among/within the groups ( P < 0.001). Tukey's post hoc test presented significant increased tensile bond strength of Er:YAG laser group. Air abrasion group showed no significant increase in tensile bond strength values ( P = 0.033). Conclusion: Dentin surface treatment with Er:YAG laser significantly improved the tensile bond strength of luting GIC compared to air-abraded and untreated dentin.

“…Therefore, the bonding effectiveness of these functional monomers relies largely on the chemical interaction with dental HAp, which is lower and less stable compared to that promoted by 10-MDP monomer 48 . These facts may explain why Vertise® Flow and Fusio™ Liquid Dentin used without prior phosphoric acid etching performed significantly worse than CFRCs 8,9,20,21,30,36 Other strategies to improve the bonding effectiveness of adhesive restorations involve lasers such as erbium:yttrium aluminum garnet laser (Er:YAG) or neodymium-doped yttrium aluminum garnet (Nd:YAG) 49,50 . This was confirmed in one included study 30 using Er:YAG laser (120 mJ, 10 Hz, 1.20 W) at 1 mm of distance from primary enamel.…”

Aim: To review the current literature regarding the bond strength of self-adhesive flowable resin composites (SAFRCs) to tooth structure, comparing the outcomes with conventional flowable resin composites (CFRCs). Methods: PubMed/Medline, EbscoHost and Scopus databases were screened (last update on November 2020) using related Medical Subject Headings (MeSH) and free terms. We included in vitro studies published in English language comparing the bond strength of SAFRCs and CFRCs to enamel and/or dentin from primary and/or permanent teeth. Results: In total, 23 articles were included. Unlike CFRCs, SAFRCs such as Vertise® Flow and Fusio™ Liquid Dentin exhibited statistically lower bond strength to enamel and dentin from permanent teeth. There were limited studies comparing the enamel bond strength of CFRCs and SAFRCs (prior phosphoric acid etching and/or adhesive system use). Also, we found few studies that evaluated the bonding effectiveness of Constic® and other SAFRCs to primary teeth. Conclusions: Current SAFRCs showed low bond strength to permanent teeth, which impedes to recommend them as a reliable alternative to CFRCs. The bonding performance of Constic® on both hard dental tissues should be evaluated on future studies. Also, more evidence assessing the bond strength of SAFRCs to primary teeth and etched enamel is needed.
