A COMPREHENSIVE EVALUATION OF APPLICATION OF LIGHT-CURED COLORED COMPOMER FOR DECIDUOUS TEETH

Twinky Star colored compomer produced by VOCO GmbH is a new type of filling material designed with seven different colors. Previous studies have shown that using the colored filling material can induce children's curiosity and increase the acceptance for dental treatment. However, few studies have been conducted to evaluate it. Hence, the present study was designed to assess the mechanical and adhesive properties of this new compomer, examine its biological safety, and evaluate the effects of its clinical application on children's adherence to dental treatment and the subsequent therapeutic outcomes. We found that Twinky Star compomer has a high compressive strength, good biaxial flexural strength, low wear rate, and good adhesive properties, and had little in vitro cytotoxic effects and did not cause apparent hemolysis in vivo. Finally, application of the compomer helped to improve children's acceptance of treatment without affecting the subsequent therapeutic outcomes in the follow-up examinations. To summarize, the findings suggest that Twinky Star compomer meets the performance requirements for dental fillings, and can be recommended for future clinical application.
