■目的是比较各种草药消毒剂对不可逆水胶体印象的功效,并研究三种草药消毒剂和化学消毒剂对特定病原体的有效性。
■体外比较研究。
■遵循以下方法来实现这些目标。使用不可逆的水胶体印模材料为每位选定的患者制作了四个上颌印模。预消毒拭子取自牙齿17、13、27和23(牙齿编号的FDI系统)的印模部位。将印模浸入所有四种不同的消毒剂中,例如2%的戊二醛,芦荟溶液,50%印尼姆油,和苹果醋溶液,然后从相同的地点17,13,27,23取消毒后的拭子,然后在绵羊血琼脂上培养并检查其生长情况,和草绿色链球菌的菌落形成单位(CFU),变形链球菌,血链球菌,和粘性放线菌。对各研究组消毒前和消毒后的数值进行对比分析。
■描述性分析,KruskalWallis测试,MannWhitney事后测试,威尔科克森签署等级测试。
■结果显示,S.viridans的平均CFU,S.mutans,S.sanguis,与消毒前样品相比,消毒后样品和粘菌具有统计学意义。与A.vera和苹果醋组相比,对照组和50%印尼姆油组中所有4种微生物的平均CFU的多重比较显着降低。
■S.viridans的CFU,S.mutans,S.sanguis,与对照组相比,在50%的印em油组和粘性A。因此,50%的印鉴油是对藻酸盐印模进行消毒的可行选择。
The aim was to compare the efficacy of various herbal disinfectants on irreversible hydrocolloid impressions and to investigate the effectiveness of three herbal disinfectants and a chemical disinfectant against particular pathogens.
In vitro -a comparative
study.
The following methodology was followed to achieve the objectives. Four maxillary impressions were made for each selected patient with irreversible hydrocolloid impression material. The predisinfection swabs were taken from impression sites of teeth 17, 13, 27, and 23 (FDI system of tooth numbering). The impressions were immersed in all four different disinfectants such as 2%
glutaraldehyde, Aloe vera solution, 50% neem oil, and apple vinegar solution, then the postdisinfection swabs were taken from the same sites 17,13,27,23 and then cultured onto sheep blood agar and examined for growth, and colony forming units (CFUs) of Streptococcus viridans, Streptococcus mutans, Streptococcus sanguis, and Actinomyces viscosus. The comparative analysis was done for the predisinfection and postdisinfection values in each
study group.
Descriptive analysis, Kruskal Wallis test, Mann Whitney post hoc test, Wilcoxon signed rank test.
The results revealed that the mean CFUs of S. viridans, S. mutans, S. sanguis, and A. viscosus during postdisinfection samples were statistically significant when compared to predisinfection samples. Multiple comparison of the mean CFUs of all 4 microorganisms in the control group and in 50% Neem oil group was significantly lesser compared to A. vera and Apple Vinegar group.
CFUs of S. viridans, S. mutans, S. sanguis, and A. viscosus significantly decreased in the 50% neem oil group as well as the control group. As a result, 50% Neem oil was a viable option for disinfecting alginate impressions.
