This study determined the effects of chemical disinfecting agents on denture acrylic resins. Tested resins included the products CH Lucitone, Triad VLC, and Truliner. The disinfecting agents were sodium hypochlorite, Exspor, Cidex, and Wescodyne-D. Acrylic resin samples were placed in the various disinfecting agents and then evaluated for color changes at time intervals ranging from 15 minutes to 72 hours. No observable color change of any acrylic resin was seen before 2 hours. Both 1% sodium hypochlorite and 2% Cidex disinfectants produced the least discoloration of the acrylic resins, and Wescodyne-D disinfectant produced the most acrylic resin discoloration. Truliner resin discolored more than Triad VLC resin, and both underwent more color change than CH Lucitone resin. If manufacturers' recommended disinfecting times are followed, clinical and laboratory disinfection of acrylic resin dentures should cause no observable color change.
本研究确定了化学消毒剂对义齿丙烯酸树脂的影响。测试的树脂包括CH Lucitone、Triad VLC和Truliner产品。消毒剂有次氯酸钠、Exspor、Cidex和Wescodyne-D。将丙烯酸树脂样品置于各种消毒剂中，然后在15分钟至72小时的时间间隔内评估颜色变化。在2小时之前，未观察到任何丙烯酸树脂有颜色变化。1%的次氯酸钠和2%的Cidex消毒剂使丙烯酸树脂的变色最少，而Wescodyne-D消毒剂使丙烯酸树脂变色最多。Truliner树脂比Triad VLC树脂变色更严重，且二者的颜色变化均比CH Lucitone树脂更多。如果遵循制造商推荐的消毒时间，丙烯酸树脂义齿的临床和实验室消毒不应导致可观察到的颜色变化。
