Preparation and Performance of Filled Resin Based on Long Afterglow Materials in Gingival Wall Lifting Surgery

Abstract

The study was conducted to solve the problems of low monomer conversion rate and insufficient curing depth of dental resin complexes during curing in gingival wall elevation procedures. A dental composite resin was prepared by modifying the blue emitting long afterglow luminescent material. Then it was applied in the treatment of oral caries for experimental research. The results showed that the afterglow of the SMSED material showed high brightness and blue, with its thermoluminescence peak higher than that of the control group, reaching a maximum of 3 × 10⁶. The curing performance was better. It was 9.17 % higher than CAED and 10.27 % higher than SAED. The accuracy of the measurements for the different resins in the study was about 5.67 %. In addition, the double bond conversion rate of the composite resin doped with 1 wt.% increased by 114.16 % compared to the composite resin without SMSED doping. The structure and size of composite resins containing 1 wt.% research materials were more stable. Overall, the cell survival rate for 1 – 3 days was higher than 70 %, indicating that the modified composite resin had lower toxicity to L929 cells. Overall, the performance of the dental composite resin prepared by modifying the blue emitting long afterglow luminescent material is significantly improved, indicating its effectiveness and practicality. It can be practically applied in the treatment of dental caries in gingival wall lifting surgery.
