目的：研究4种不同清洁方式对义齿树脂基托表面粗糙度的影响。方法：制作20个树脂圆片样本并随机分为4组。A组为对照组，样本置于清水中；B，C，D为实验组，其清洁方式分别为：牙刷+清水、牙刷+牙膏、义齿清洁片溶液。B，C组每次处理时间30 s，D组每次处理5 min，重复处理过程1080个循环。处理后对4组样品进行表面粗糙度的检测并对结果进行分析。结果：不同的清洁方式会对义齿树脂基托表面粗糙度产生不同影响，其中B，C组的树脂基托表面粗糙度明显大于A组(P<0.05)，D组与A组间的差异无统计学意义(P>0.05)。结论：牙刷+牙膏组清洁义齿的方式对义齿基托的表面粗糙度影响较大；义齿清洁片溶液浸泡对义齿的基托表面粗糙度影响较小，不会对树脂基托表面造成明显划痕。

Objective: To determine the effect of different denture cleaning methods on surface roughness in resin denture base. <br> Methods: We established 20 wafer samples of fuser base resin (14 mm×14 mm×3 mm), and then randomly divided them into 4 groups: group A was the control group, which were placed in water, while group B, C and D were the experimental groups, whose cleaning methods were toothbrush and water, toothbrush and toothpaste, denture cleaning tablets, respectively. Each procedure in group B and C lasted for 3 seconds, but group D lasted 5 min and repeated for 1080 times. We cleaned twice a day to simulate the method of cleaning dentures. Surface roughness was checked after different procedures by laser scanning confocal microscopy. <br> Results: Significant difference on surface roughness was found between group B, C and A (P<0.05), while no significant difference in the surface roughness between group A and D (P>0.05). Conclusion: Significant surface roughness alterations have been observed in toothbrush and toothpaste group, but no change has been found in denture cleaning tablets group, which does not produce scratches on the surface of resin denture base.
