“…Another trend is modification of restorative materials with fluoride compounds such as NaF, CaF 2 , SnF 2 , SrF 2 , KF, which would release fluoride ions and contribute to remineralization of dental tissue within the cavity and in the environment surrounding the restoration [1]. Cariostatic effect of fluoride ions is widely documented and clinically proven [2–4] and encourages researchers to develop novel fluoride-based restorative materials [5, 6]. In order to enhance fluoride ions activity, combination with calcium compounds has been introduced [7].…”

Aim of the study was to evaluate mechanical properties of light-curing composite materials modified with the addition of calcium fluoride. The study used one experimental light-curing composite material (ECM) and one commercially available flowable light-curing composite material (FA) that were modified with 0.5–5.0 wt% anhydrous calcium fluoride. Morphology of the samples and uniformity of CaF2 distribution were analyzed using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Mechanical properties were tested after 24-hour storage of specimens in dry or wet conditions. Stored dry ECM enriched with 0.5–1.0 wt% CaF2 showed higher tensile strength values, while water storage of all modified ECM specimens decreased their tensile strength. The highest Vickers hardness tested after dry storage was observed for 2.5 wt% CaF2 content in ECM. The addition of 2.0–5.0 wt% CaF2 to FA caused significant decrease in tensile strength after dry storage and overall tensile strength decrease of modified FA specimens after water storage. The content of 2.0 wt% CaF2 in FA resulted in the highest Vickers hardness tested after wet storage. Commercially available composite material (FA), unmodified with fluoride addition, demonstrated overall significantly higher mechanical properties.

“…A number of researches [14, 26, 32, 38, 39, 49–52] proved that the highest amount of fluoride ions is released as follows: glass ionomer cements, resin modified glass ionomer cements, compomers, and the least composite materials. Authors suggest that modification of dental materials with CaF 2 -based compound could be major issue that limits dental caries development.…”

“…Bacteria present in biofilm also induce further adhesion of microorganism to composite filling [14, 15]. Also, even correctly applied composite restorations with time undergo hydrolytic degradation due to water sorption, swelling, plasticization, or enzymatic decomposition.…”

“…Fluoride prevents demineralization process and enhances remineralization of enamel. Both processes take place in low concentration of fluoride ions in enamel amounting up to 0.03 ppm [8, 14, 20, 24–27]. Due to higher organic substance amount in dentine, the fluoride amount indispensable to enhance both processes should be 10 times higher than for enamel [28].…”

The aim of the study was to evaluate antibacterial activity of composite materials modified with calcium fluoride against cariogenic bacteria S. mutans and L. acidophilus. One commercially available conventional light-curing composite material containing fluoride ions (F2) and two commercially available flowable light-curing composite materials (Flow Art and X-Flow) modified with 1.5, 2.5, and 5.0 wt% anhydrous calcium fluoride addition were used in the study. Composite material samples were incubated in 0.95% NaCl at 35°C for 3 days; then dilution series of S. mutans and L. acidophilus strains were made from the eluates. Bacteria dilutions were cultivated on media afterwards. Colony-forming unit per 1 mL of solution (CFU/mL) was calculated. Composite materials modified with calcium fluoride highly reduced (p < 0.001) bacteria growth compared to commercially available composite materials containing fluoride compounds. The greatest reduction in bacteria growth was observed for composite materials modified with 1.5% wt. CaF2. All three tested composite materials showed statistically greater antibacterial activity against L. acidophilus than against S. mutans.

“…One reason for this high incidence is that resin composites and dentin bonding systems are not able to prevent secondary caries. Therefore, several trials have examined the possibility of adding antibacterial materials to the dentin bonding system 9,10) . As a novel nanomaterial, CNTs also have antibacterial activity 11) .…”

This study developed carbon nanotube coatings for the dentin surface and investigated the bonding strength and the in vitro antibacterial properties of carbon nanotube-coated dentin. Single-walled carbon nanotubes and multi-walled carbon nanotubes were first modified and then characterized using Fourier-transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. Second, dentin samples were coated using either single-walled carbon nanotubes or multi-walled carbon nanotubes and observed under a scanning electron microscope. Then, the shear bonding strength and antibacterial properties of the dentin samples were tested. The results showed that both modified single-walled carbon nanotubes and multi-walled carbon nanotubes formed a stable coating on the dentin surface without affecting the shear bonding strength. Moreover, the antibacterial properties of the single-walled carbon nanotube-coated samples was obviously superior to those of the multi-walled carbon nanotubecoated samples. Consequently, single-walled carbon nanotube coating may be an antibacterial agent for potential application in the dental bonding field.
