多酚对纳米树脂颜色及透光率的影响
Effects of polyphenols on the color and transmittance of nanocomposites
摘要
Abstract
Objective:To investigate effects of polyphenols on the color and light transmittance of three kinds of nanocomposites. Method:Three kinds of nanocomposites(3M Z350 A2、A3 colour,Shofu Beautiful ⅡA2、A3 colour,Kuraray Clearfil A2、A3 colour) were tested in the study. There were twelve samples for each group. Changes in colour and light transmittance of test samples were determined by PANTONE X-rite Ci7600 spectrophotometer before and after 1,2,3 and 4 weeks. The samples were random infusioned in the food including polyphenols (coffee、red wine、green tea and artificial saliva) using the CIE L*a*b*system by a colourimeter. Result:The colour and light transmittance of resin disks submerged in liquid were different in different immersion time. The values of colour variation ranged from 0.26 to 26.63. Among all the groups, red wine showed the maximum colour variation value while artificial saliva showed the minimum colour variation value ,and amomg all the resin disks, 3M had the best color stability while clearfil had the worst color stability. The overall light transmittance reduced and A3 colour variation value was less than A2 colour. Conclusion:The polyphenols in food cause color and light transmittance change in the resin materials. The resin restoration is still insufficient and clinical choose should weigh the pros and cons.关键词
