This paper describes the results obtained in the optimization of the composition of dental sealants in relation to the nature and proportions of monomer mixtures and photoinitiating system employed. The quantification and variation of certain parameters which determine the quality of a dental sealant (such as viscosity and penetrating power, residual double bonds, solubility and absorption, volume shrinkage and certain specific mechanical properties) have resulted in the development of new formulations. The composition which has achieved the best results of all the above properties was that corresponding to the monomer mixture bis-GMA/tri(ethylene glycol) dimethacrylate (TEGDMA) 40/60 wt%, and the photoinitiating system camphorquinone (CQ) with co-initiators N,N,3,5-tetramethyaniline (TMA) or N,N-dimethyl-p-toluidine (DMPT) in the ratio 1:1. The final properties and characteristics of the obtained formulations are superior to those of commercial dental sealants currently in use.
本文描述了在优化牙科密封剂成分方面所取得的成果，该优化涉及所使用的单体混合物的性质和比例以及光引发体系。对某些决定牙科密封剂质量的参数（如粘度和渗透力、残余双键、溶解性和吸收性、体积收缩率以及某些特定的机械性能）进行量化和变化，从而开发出了新的配方。在上述所有性能方面取得最佳结果的配方是对应于单体混合物双酚A双甲基丙烯酸缩水甘油酯（bis-GMA）/三（乙二醇）二甲基丙烯酸酯（TEGDMA）重量比为40/60，以及光引发体系樟脑醌（CQ）与共引发剂N，N，3，5-四甲基苯胺（TMA）或N，N-二甲基对甲苯胺（DMPT）比例为1:1的配方。所获得配方的最终性能和特性优于目前使用的商业牙科密封剂。
