In vitro and In vivo evaluation of resin composites fluorescence

Antibacterial and fluorescent clear aligner attachment resin modified with chlorhexidine loaded mesoporous silica nanoparticles and zinc oxide quantum dots

“…Studies have revealed that most of the restorative composite resins and the natural tooth enamel exhibited the similar color of the fluorescence (Kim et al, 2016;Lopes et al, 2021). A recent study reported that the fluorescence intensity of Filtek Z350 XT under ultraviolet was even weaker than natural tooth enamel (Lopes et al, 2021). The strong yellowish fluorescence of FAR and AFAR-2 could help the professional to identify the resin and the enamel with the assistance of an ultraviolet radiator.…”

“…12 C) showed both the enamel and Filtek Z350 XT could emit similar blue fluorescence, making it hard to distinguish from each other. Studies have revealed that most of the restorative composite resins and the natural tooth enamel exhibited the similar color of the fluorescence (Kim et al, 2016;Lopes et al, 2021). A recent study reported that the fluorescence intensity of Filtek Z350 XT under ultraviolet was even weaker than natural tooth enamel (Lopes et al, 2021).…”

Quantitative and Qualitative Assessment of Fluorescence in Aesthetic Direct Restorations

“…Besides this, the precise composition of these materials is proprietary information, therefore, it is particularly hard to define which component is responsible for the fluorescent effect. In the international scientific literature, we found only comparative studies between different material brands or studies that compare natural teeth with restorative materials [4,5,10,11].…”

“…The qualitative evaluation of the fluorescence intensity was assessed by a qualitative visual method [10] by two of the authors (ZSBV and BKM). Therefore, the samples were introduced in a custom-made black box and illuminated by a UV light source at the intensity of 385 nm.…”
