Denture-related stomatitis is probably the most common form of oral candidiasis and its reported prevalence varies widely ranging up to 65%. In this thorough study, we evaluate the effect of Delmopinol application on Candida albicans adherence on heat cured denture base acrylic resin.
A total of 40 specimens of heat-cured acrylic resin were made, 20 specimens were contaminated before Delmopinol treatment and 20 specimens were contaminated after Delmopinol treatment. The each specimen in each tube was individually transferred to a spectrophotometer at 530 nm wavelength in order to measure the turbidity degree, through the transmittance. Aliquots of 10 μL of each tube was then collected and inoculated into agar sabouraud plates containing 500 mMol/L of sucrose, which was incubated for 24 hours at 37°C, in order to check microbial growth.
Mean of the turbidity Degree of contamination after Delmopinol application (1440.80, colony-forming unit [CFU] [×10 6 /ml]) was significantly higher than the mean of the turbidity degree of contamination before Delmopinol application (550.85 CFU [×10 6 /ml]).
Heat-cured acrylic resin shows greater reduction in adherence of Candida albicans by contamination after Delmopinol application as compared with contamination before Delmopinol application.
义齿性口炎可能是口腔念珠菌病最常见的形式,其报告患病率差异很大,高达65%。在这项全面的研究中,我们评估了地莫匹醇应用对白色念珠菌在热固化义齿基托丙烯酸树脂上黏附的影响。
共制作40个热固化丙烯酸树脂标本,20个标本在应用地莫匹醇治疗前被污染,20个标本在应用地莫匹醇治疗后被污染。将每个试管中的每个标本分别转移至波长为530nm的分光光度计中,通过透光率测量浑浊度。然后从每个试管中收集10μL的等分试样,并接种到含有500mmol/L蔗糖的沙氏琼脂平板中,于37℃孵育24小时以检查微生物生长情况。
应用地莫匹醇后污染的浑浊度平均值(1440.80,菌落形成单位[CFU][×10⁶/ml])显著高于应用地莫匹醇前污染的浑浊度平均值(550.85CFU[×10⁶/ml])。
与应用地莫匹醇前污染相比,热固化丙烯酸树脂在应用地莫匹醇后污染时白色念珠菌的黏附减少更为明显。
