The viscosities of the prepolymers were much lower than that of the Bis-GMA control. From the results of 1H-NMR analysis, the chemical structures of the prepolymers were similar to that of Bis-GMA. In addition, the polymerization shrinkage, photoconversion, polymerization depth, and diametral tensile strength of the dental sealants formulated with 80-3MA and 4000-3MA mixture prepolymers exhibited comparable to or better than those of the existing Bis-GMA-based one. These results suggest that the novel 3MA methacrylated prepolymers which have no endocrine disrupter can be an alternative to Bis-GMA and be applicable to biocompatible dental materials. 한국생체재료학회 신규 3MA 메타크릴레이트 프리폴리머를 이용한 치과용 치면열구전색재의 제조 및 특성 Preparation and Characteristics of Dental Pit and Fissure Sealants with Novel 3MA Methacrylated Prepolymers Article 2 생체재료학회지, v.11, no.1, pp.43 - 50 생체재료학회지 11 1 43 50 kci ART001057906 Dental pit and fissure sealant Endocrine disrupter Bis-GMA Bisphenol A Methacrylated prepolymer 3MA mixture. .......
