Novel Polymerization of Dental Composites Using Near-Infrared-Induced Internal Upconversion Blue Luminescence

Abstract: Blue light (BL) curing on dental resin composites results in gradient polymerization. By incorporating upconversion phosphors (UP) in resin composites, near-infrared (NIR) irradiation may activate internal blue emission and a polymerization reaction. This study was aimed to evaluate the competency of the NIR-to-BL upconversion luminance in polymerizing dental composites and to assess the appropriate UP content and curing protocol. NaYF4 (Yb3+/Tm3+ co-doped) powder exhibiting 476-nm blue emission under 980-nm N… Show more

“…Data in the literature show that a blue laser is able to activate polymerization in dental composites [ 42 ], and it may involve the light curing of the enamel surface treatment [ 43 ]. Therefore, light irradiation is able to give a boost the chemical reactions within the Tiefenfluorid reagents during fluoride formation.…”
