“…BAG Among bioceramics, BAG is a relatively new material which has been incorporated into dental resin composites and adhesives. A total 20 studies [92][93][94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111] was found as per the inclusion criteria, whereby seven studies 92,[94][95][96]98,106,108) were based on fluoride-based bioactive glass (F-BAG). Few studies showed doping of zinc 101,102,107) , silver 110) , and niobiophosphate 109) in BAG powders.…”

Currently, much has been published related to conventional resin-based composites and adhesives; however, little information is available about bioceramics-based restorative materials. The aim was to structure this topic into its component parts and to highlight the translational research that has been conducted up to the present time. A literature search was done from indexed journals up to September 2017. The main search terms used were based on dental resin-based composites, dental adhesives along with bioactive glass and the calcium phosphate family. The results showed that in 123 articles, amorphous calcium phosphate (39.83%), hydroxyapatite (23.5%), bioactive glass (16.2%), dicalcium phosphate (5.69%), monocalcium phosphate monohydrate (3.25%), and tricalcium phosphate (2.43%) have been used in restorative materials. Moreover, seven studies were found related to a newly developed commercial bioactive composite. The utilization of bioactive materials for tooth restorations can promote remineralization and a durable seal of the tooth-material interface.

“…Each specimen was evaluated at a wavelength range of 500–4,000 cm −1 , a resolution of 4 cm −1 , and with 32 scans. A thin layer of PUDMA X or adhesive (5 mm diameter, 0.25 mm thick, n = 5) was applied onto a potassium bromide pellet, then evaluated using an FTIR spectrometer with spectra ranging from 900 to 4,000 cm −1 , as described previously . The specimens containing FL and SB2 adhesives were light‐cured for 20 and 10 s, respectively, as recommended and without solvent volatilization.…”

In this study, polyurethane dimethacrylate (PUDMA) was synthetized from different components and incorporated into a direct resin composite restoration system with the aim to buffer tooth–resin interfacial stresses and maintain the marginal adaptation. The tensile strength, elongation at fracture (ε), and thermal stability of the PUDMA layer were characterized, showing a tensile strength of 22 MPa, an ε of 112%, and a thermal decomposition temperature of about 282°C. In addition, the degree of conversion, water sorption/solubility, hydrophobicity, microtensile bond strength (μTBS), marginal leakage, and cytotoxicity in vitro were evaluated for the PUDMA layer. The data were analyzed using one‐way ANOVA, except for leakage depths (which were analyzed using the Wilcoxon paired‐rank test). The level of significance was set at 0.05. Compared with dental adhesives, PUDMA displayed a higher degree of conversion, lower water sorption/solubility, and improved hydrophobicity and biocompatibility in vitro. After thermocycling, the μTBS of the restoration system containing PUDMA had increased compared with the μTBS at 24 h. Restorations containing PUDMA showed lower leakage depths than those which did not contain PUDMA. In conclusion, because of its hydrophobic and elastic nature, the PUDMA layer, when used as an intermediate between tooth and resin restoratives, may buffer interfacial stresses, improve the stability and durability of the bonding interface, and reduce microleakage.

“…Though mono-functional POSS particles resulted in a highly declined conversion and bioactive glass particles strongly enhanced the viscosity, apparently, their application in dental adhesives is limited to specic uses and substances. 184 Tooth whitening agents were necessarily nano-modied to increase the whitening efficiency and decrease their harmful side effects. For example, calcium peroxide nanoparticles could penetrate deeper into the tooth structure through micro and nano cracks, make longer surface contact, and increase the effectiveness of the whitening agent.…”
