“…When the composite groups were compared, the BAG group showed the greatest color change after immersion for 1, 7, and 30 days. Similar to our findings, Hyun et al reported that color changes were higher in a BAG group as compared with those in a BAG‐Flor group . Previous research showed that BAG released calcium ions during dissolution, which elevated the pH of interfacial solutions and prevented the attachment and growth of microorganisms .…”

Objective The aim of this study was to evaluate the effect of the addition of antibacterial agents to composites on color changes after immersion of these composites in different beverages. Materials and Methods Composite resins containing antibacterial agents (bioactive glass [BAG] and nano‐zinc silicium [NZS]) and a control group (no agent) were produced. The treatment groups were as follows: control, BAG, NZS, and BAG + NZS. Forty‐eight disc‐shaped specimens (8 mm in diameter and 2‐mm thick) were prepared, with 12 specimens in each group. Color measurements were measured before and after immersion of the specimens in staining solutions (tea, coffee, and water) for 1, 7, and 30 days. The color measurements were repeated, and changes were calculated using the CIEDE2000 (ΔE00) formula. Results Color differences were analyzed using a two‐way analysis of variance and Tukey's tests. Significant differences were observed among the composite groups and solutions after all days in all the groups (P < .05). Conclusions The addition of the antibacterial agents did not reduce color changes. Color changes of the specimens immersed in coffee were greater than those of the specimens immersed in the other beverages, with the highest color change observed in the BAG groups. Clinical Significance The results provide information on the color stability of composite resins containing BAG and NZS and the staining potential of drinks commonly consumed in daily life. In terms of esthetic dentistry, BAG and NZS containing composites should be used in the posterior region, where there is a high risk of caries due to coloration.

“…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.

“…With the development of nanotechnology, the application of nanoparticles is evolving quickly to improve dental materials [13–15]. Studies have reported several types of promising antimicrobial nanoparticles including silver [16], ZnO [17], TiO 2 [18], and bioactive glass [19]. In addition, quaternary ammonium methacrylates (QAMs) are a class of cationic compounds with a broad spectrum of antimicrobial effects [11, 12].…”

Recurrent caries often occurs and is a primary reason for the failure of dental composite restorations. The objectives of this study were to: (1) develop a bioactive composite containing dimethylaminohexadecyl methacrylate (DMAHDM), (2) investigate its antibacterial effects and suppression on biofilm growth, and (3) investigate its ability to modulate biofilm species composition for the first time. DMAHDM was incorporated into a composite at mass% of 0%, 0.75%, 1.5%, 2.25% and 3%. A commercial composite Heliomolar served as a comparative control. A biofilm model consisting of Streptococcus mutans (S. mutans), Streptococcus sanguinis (S. sanguinis) and Streptococcus gordonii (S. gordonii) was tested by growing biofilms for 48 h and 72 h on composites. Colony-forming units (CFUs), metabolic activity and live/dead staining were evaluated. Lactic acid and polysaccharide productions were measured to assess biofilm cariogenicity. TaqMan real-time polymerase chain reaction was used to determine the proportion of each species in the biofilm. DMAHDM-containing composite had a strong anti-biofilm function, reducing biofilm CFU by 2–3 orders of magnitude, compared to control composite. Biofilm metabolic activity, lactic acid and polysaccharides were decreased substantially, compared to control (p < 0.05). At 72 h, the cariogenic S. mutans proportion in the biofilm on the composite with 3% DMAHDM was 19.9%. In contrast, an overwhelming S. mutans proportion of 92.2% and 91.2% existed in biofilms on commercial control and 0% DMAHDM, respectively. In conclusion, incorporating DMAHDM into dental composite: (1) yielded potent anti-biofilm properties; (2) modulated the biofilm species composition toward a non-cariogenic tendency. The new DMAHDM composite is promising for applications in a wide range of tooth cavity restorations to modulate oral biofilm species and combat caries.
