Abstract

Purpose: This study investigated the efficacy of various antiseptics for disinfection of rubber dams used during endodontic treatment, the duration of disinfection effectiveness, and the disinfection protocol employed by dental schools in Thailand.

Methods: The efficacy of 10% povidone-iodine, 1.5% tincture iodine and 70% ethyl alcohol in eliminating Enterococcus faecalis (E. faecalis) and Candida albicans (C. albicans) on the rubber dam was investigated. Time duration of disinfection was evaluated at 0, 30, 60, and 120 min. The two-step disinfection method adopted at Thai dental school was examined. Independent t-test or Kruskal-Wallis followed by a Dunnett's test was used for statistical analysis.

Results: Among the three antiseptics, 10% povidone and 1.5% tincture iodine eradicated the microorganisms completely, whereas 70% ethyl alcohol did not achieve a statistically significant decrease. The duration of sterilization effectiveness was 120 min for 10% povidone-iodine, but bacteria were eliminated only at 0 min by 1.5% tincture iodine. The results also indicated that the two-step protocol scarcely eliminated the microorganisms.

Conclusion: The best antiseptic for rubber dam disinfection is 10% povidone-iodine, which remains effective for 120 min. The two-step protocol typically practiced in Thai dental schools needs to be updated. The use of 10% povidone-iodine alone is adequate for complete eradication of E. faecalis and C. albicans.

根管治疗前橡胶坝灭菌防腐剂的效果。
目的:本研究调查了各种防腐剂对根管治疗过程中使用的橡胶坝的消毒效果、消毒效果的持续时间以及泰国牙科学校采用的消毒方案,研究了1.5%碘酒和70%乙醇对橡胶坝上粪肠球菌和白色念珠菌的杀灭效果。消毒时间分别为0、30、60和120分钟。对泰国牙科学校采用的两步消毒方法进行了检查。采用独立t检验或Kruskal-Wallis检验,然后采用Dunnett检验进行统计分析。结果:在三种防腐剂中,10%聚维酮和1.5%碘酒完全根除了微生物,而70%乙醇没有达到统计学上显著的减少。10%聚维酮碘的杀菌效果为120min,而1.5%碘酒的杀菌效果仅为0min。结果还表明,两步方案几乎没有消除微生物。结论:橡胶坝消毒的最佳防腐剂是10%聚维酮碘,其有效期为120分钟。泰国牙科学校通常采用的两步方案需要更新。单独使用10%聚维酮碘就足以完全根除粪肠球菌和白色念珠菌。
