摘要: 目的 探讨LED光固化灯与传统卤素灯对不同颜色复合树脂的固化深度的影响。方法 选取FiltekTM Z350和Premisa两种树脂,FiltekTM Z350组选取A1B,A2B,A3B 3种颜色,Premisa组选取A1E,A2E,A3E 3种颜色,自制实验模具,将树脂填入模具。每种颜色树脂制作60例试件,分为3组,每组20例,分别用2种新型LED光固化灯Demi LED和Bluephase○R20i与传统卤素灯ALC-50在标准条件下照射试件,检测固化深度。结果 Demi LED光照10 s、 Bluephase○R20i光照10 s树脂的固化深度均达到3 mm,与传统的卤素光固化灯ALC-50光照40 s有显著差异,但前两者之间无显著差异。Premisa树脂中2种LED照射组A1E,A2E和A3E 3种颜色之间固化深度有统计学差异。结论 在相同条件下,Demi LED和Bluephase○R 20i照射10 s树脂固化深度大于传统卤素灯ALC-50照射同一树脂40 s,适合临床应用。树脂颜色的加深对树脂固化深度有影响。

Abstract: Objective To study the effects of LED and halogen curing lights on the cure depth of composite resin of different colors.Methods Standard cylinder samples of FiltekTM Z350 and Premisa light curing composite were prepared for cure depth test. FiltekTM Z350 resin had three colors:A1B,A2B and A3B.Premisa resin had three colors:A1E,A2E and A3E.Composite resin of each color was made into 60 samples.The samples were divided into three groups equally.The three groups were cured by Demi LED curing light,Bluephase○R 20i curing light and ALC-50 halogen curing light respectively.Results The mean depth of the samples cured by Demi LED curing light for 10 s and Bluephase○R20i LED curing light for 10 s exceeded 3 mm.The difference between Demi LED and ALC-50,Bluephase○R20i and ALC-50 was significant,but there was no significant difference between Demi LED and Bluephase○R20i.The difference between A1E,A2E and A3E of Premisa cured by two LED curing lights was significant.Conclusions Under the same conditions,the cure depth of the two LED curing lights curing for 10 s is superior to the performance level of halogen curing light curing for 40 s.The two LED curing lights are suitable for routine oral clinical application.The darkening of composite resin color can makes a difference to the cure depth.
