The depth of cure using blue-light photocuring units (BL) is limited by tooth structure and qualities the restorative material through which activating wavelength must pass. Recent developments incorporate an infrared (IR) activated upconversion (UC) fluorescence a lining agent filled with nanocrystals NaYF4 doped YB+3 Tm+3 that emit both blue violet light locally at interface liner resin. purpose this study was to evaluate BL 975 nm power transmission dental tissues materials.
