【摘要】：目的:比较不同类型义齿清洁剂对着色热凝基托树脂和树脂人工牙的清洁效果。方法:将40块规格相同的热凝基托树脂试件和40颗贺利氏树脂人工中切牙,浸泡于咖啡、绿茶和酱油的混合液中4周,各随机分为4组(n=10),按使用说明分别浸泡在Polident、Steradent清洁片配成的溶液、质量分数为0.5%次氯酸钠溶液和蒸馏水(对照组)中4 h,使用色差仪和电子比色仪分别测量热凝基托树脂和树脂人工牙着色前后、清洁剂浸泡后的色度值,计算试件处理前后的色差(ΔE)并进行统计学分析。结果:在着色前后,4组热凝基托树脂和4组树脂人工牙ΔE无统计学差异(P0.05)。在着色后与清洁后的ΔE值,0.5%次氯酸钠组Polident组和Steradent组蒸馏水组(P0.05);Polident组与Steradent组之间无统计学差异(P0.05)。在着色前与清洁后,蒸馏水组的ΔE大于其他3组(P0.05);其他3组之间无统计学差异。结论:0.5%次氯酸钠、Polident和Steradent对着色热凝基托树脂和树脂人工牙均有有效的清洁效果,其中0.5%次氯酸钠优于Polident和Steradent,Polident和Steradent效果相同。
[Abstract]:Objective: to compare the cleaning effects of different types of denture cleaners on colored thermosetting base resin and resin artificial teeth. Methods: 40 specimens of thermocoagulated base resin of the same size and 40 artificial middle incisors of Hollis resin were immersed in the mixed solution of coffee, green tea and soy sauce for 4 weeks. Each group was randomly divided into 4 groups (n = 10). The specimens were immersed in Polident, according to the instructions of use, and the teeth were immersed in the mixed solution of coffee, green tea and soy sauce for 4 weeks. The solution of Steradent cleaning tablet was composed of 0.5% sodium hypochlorite solution and distilled water (control group) for 4 hours. The thermocoagulation base resin and resin artificial teeth were measured by colorimeter and electronic colorimeter, respectively. The color difference (螖 E) of the sample before and after treatment was calculated and analyzed statistically. Results: before and after coloring, there was no significant difference in 螖 E between 4 groups and 4 groups (P0.05). After coloring and cleaning 螖 E value, 0.5% sodium hypochlorite group Polident group and Steradent group distilled water group (P0.05); Polident and Steradent group) had no statistical difference (P0.05). Before and after cleaning, 螖 E of distilled water group was higher than that of other 3 groups (P0.05), but there was no statistical difference among the other three groups. Conclusion: 0.5% sodium hypochlorite, Polident and Steradent have effective cleaning effects on colored thermosetting base resin and resin artificial teeth, and 0.5% sodium hypochlorite is superior to Polident and Steradent,Polident and Steradent in the same effect.
