The BPA-3MA(bisphenol-A trimethacrylate) in which one of two hydroxy group was
substituted by methacrylate was synthesized by reaction of Bis-GMA with methacryloyl
chloride. Two investigate the possibility to apply BPA-3MA as matrix of composite
resin or pit and fissure sealant, BPA-3MA(3MA) or Bis-GMA(GMA) as matrix,
TEGDMA as diluent, CQ as photosensitizer, EDMAB as photoinitiator and 5 ¥ìm
pyrogenic silica as filler were used for making experimental sealants. In addition, these
experimental sealants were compared to a commercial Concise L/C White sealant(CLW,
3M Co., U.S.A) for flexural strength, diametral tensile strength, amount of abrasion,
surface hardness, water sorption and solubility, and degree of conversion.
The flexural strength of CLW was the highest value but there was not significant
difference with 3MA. Diametral tensile strength of all 3 groups were similar(p>0.05) and
the amounts of abrasion of 3MA and GMA were less than that of CLW(p<0.05). The
surface hardness of 3MA was higher than that of GMA(p<0.05) but similar to that of
CLW. The water sorption of 3MA was less than that of GMA and CLW(p<0.05) and
the solubilities of 3MA and CLW were less than that of GMA(p<0.05). GMA and CLW
were relatively polymerized well as compared to 3MA.
From these results, pit and fissure sealant using trifunctional BPA-3MA as matrix
had superior physical and mechanical properties to existing Bis-GMA sealant.
Furthermore, it will be possible to develope composite resin having superior properties to
existing composite resin.
