Abstract:

Objective:
To test the effects of two kinds of diaryliodonium on the degree of conversion (DC), the compressive strength (CS) and the cure depth (CD) of the light-curing composite resin.
Methods:
BisS-GMA was used as reisin matrix, with TEGDMA as diluent and SiO2 as inorganic filler. CQ, DMAEMA and two different kinds of diaryliodonium (diphenyliodonium hexafluorophosphate and bis (p-tolyl) iodonium hexafluorophosphate) were used as photoinitiator, respectively. The DC, CS, CD were measured and compared by the FTIR spectroscopy, and the tensile strength of machine et al.
Results:
Diaryliodonium led to greater DC, CS, and CD of the light-curing composite resin. The DC, CS, and CD of the light-curing composite resin increased more with bis (p-tolyl) iodonium hexafluorophosphate than with diphenyliodonium hexafluorophosphate.
Conclusion:
Diaryliodonium can improve the DC, CS, and CD properties of light-curing composite resin. Bis (p-tolyl) iodonium hexafluorophosphate has better performance than diphenyliodonium hexafluorophosphate in improving photosensibility and solubility of the photoinitiator system.
