【摘要】：目的:通过观察不同浓度中药消毒剂对口腔硅橡胶印模消毒效果及材料精确度影响,探讨中药消毒剂应用于口腔硅橡胶印模消毒的可行性。方法:选取以ADA(美国牙科协会)推荐的标准模具制成的口腔印模200个,依据印模材料不同分为100个加成型,100个缩合型,每种印模根据使用消毒剂情况随机分为五组:对照组,中药高、中、低剂量组(体积分数分别为10、5、2.5%),戊二醛组(2%)),各组根据试验菌株分为金黄色葡萄球菌和白色念珠菌组,计算抑菌率,测量各组印模浸泡前后尺寸稳定性及表面粗糙度。结果:不同印模材料加成型或缩合型在浸泡前后各组尺寸变化及粗糙度比较差异均无统计学意义(P0.05),对金黄色葡萄球菌和白色念珠菌抑菌率比较:中药高剂量组中剂量组戊二醛组低剂量组,组间比较有统计学差异(P0.05),中药高剂量组与中剂量组比较差异无统计学意义(P0.05)。结论:中药消毒剂浸泡口腔硅橡胶印模消毒不影响印模精确度,不同浓度中药消毒剂均可用于口腔硅橡胶印模消毒,可优先考虑采用5%中药消毒剂浸泡消毒30min。
[Abstract]:Objective: to observe the effect of different concentrations of traditional Chinese medicine disinfectant on disinfection of silicone rubber impression and its material accuracy. To explore the feasibility of the application of traditional Chinese medicine disinfectant in disinfection of silicone rubber impression in oral cavity. Methods: 200 oral impressions made from standard mould recommended by Ada (American Dental Association) were selected. According to the different impression materials are divided into 100 additive, 100 condensed, each impression according to the use of disinfectants randomly divided into five groups: control group, Chinese medicine high, medium. The low dose group (volume fraction 10? 5?? 2.5??? The dimensional stability and surface roughness were measured before and after immersion. Results: there was no significant difference in dimensional changes and roughness of different impression materials before and after immersion. P0.05). Comparison of bacteriostatic rate of Staphylococcus aureus and Candida albicans: high dose group of traditional Chinese medicine in medium dose group, low dose group of glutaraldehyde group, there was statistical difference between groups (P 0.05). There was no significant difference between the high dose group and the middle dose group. Conclusion: soaking in the Chinese medicine disinfectant does not affect the precision of the impression. Different concentrations of Chinese medicine disinfectants can be used for oral silicone rubber impression disinfection, 5% Chinese medicine disinfectant can be preferred to soak disinfection for 30 minutes.

【正文快照】： 口腔印模是口腔相关组织的印模,在口腔修复工作中,印模的精确度是保证修复质量的重要因素[1-2],由于口腔印模在制取过程中会直接接触到患者的唾液甚至血液,在口腔印模的模型表面存在大量的致病微生物,包括金黄色葡萄球菌、溶血性链球菌、表皮葡萄球菌、白色念珠菌、乙肝病毒等
