摘要: Abstract Objective To evaluate the effect of photo-initiator on degree conversion (DC) and elution Bis-GMA HEMA for 8 one-step adhesive formulations. Methods We used Scotchbond Universal (‘SBU-CQ/amine_4.0’, 3M ESPE), containing about 2 wt% camphorquinone (CQ) ethyl-4-dimethylamino benzoate (EDMAB), an experimental ‘SBU-TPO_2.1’ version, 2.1 wt% diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO), 6 LUB adhesives (Kuraray Noritake), namely ‘LUB-CQ/amine_0.7’, ‘LUB-CQ/amine_1.4’, ‘LUB-CQ/amine_4.0’, ‘LUB-TPO_0.35’, ‘LUB-TPO_0.7’ ‘LUB-TPO_2.0’, respectively 0.35 wt% CQ EDMAB, 0.7 wt% 2.0 wt% TPO, TPO. DC was measured using micro-Raman spectroscopy. Additional specimens were immersed in ethanol 24 h to determine HPLC. Results respective SBU alike at high concentration. At low concentration, TPO significantly more efficient than CQ/amine (LUB only). A statistically significant positive concentration noted both inverse CQ/amine- TPO-containing adhesives. strong correlation found between (R2 = 0.744, p = 0.026), (R2 = 0.913, p = 0.002) Significance The kind affect Bis-GMA/HEMA elution. can be as alternative CQ/amine.
