The purpose of this study was to analyze the effect of denture cleansers on Candida albicans biofilm formation over resilient liners and to evaluate compatibility between resilient liners and denture cleansers.
Acrylic resin (Lucitone 199®) and 3 resilient liners (COE-SOFT™, GC RELINE™ and SOFRELINER TOUGH TOUGH®) were incubated in denture cleansers (Polident® and Cleadent®) for 8 hours a day and in unstimulated saliva for 16 hours a day (n=25/gp) for 60 days. Two-way and three-way repeated measures ANOVA were performed to compare the surface roughness (Ra), pH and C. albicans binding level by radioisotope (α=0.05). The statistical significance of the relation between Ra and adhesion was evaluated by correlation analysis.
THE DEGREE OF RA WAS SIGNIFICANTLY DECREASED IN THE FOLLOWING ORDER: COE-SOFT™, acrylic resin, GC RELINE™ and SOFRELINER TOUGH®. The immersion in denture cleansers significantly increased Ra of resilient liners, except for SOFRELINER TOUGH® in Cleadent®. No significant differences in pH curves were observed among groups immersed in distilled water and denture cleansers. The binding levels of C. albicans were significantly decreased in the following order: COE-SOFT™, GC RELINE™, SOFRELINER TOUGH®, and acrylic resin. The immersion in Cleadent® seemed to decrease C. albicans binding level on GC RELINE™ and SOFRELINER TOUGH®.
Based on the C. albicans binding levels results, it is not recommended to immerse COE-SOFT™ in denture cleansers, and GC RELINE™ and SOFRELINER TOUGH® should be immersed in Cleadent®.
本研究旨在分析义齿清洁剂对弹性衬垫上白色念珠菌生物膜形成的影响,并评估弹性衬垫与义齿清洁剂之间的相容性。
将丙烯酸树脂(Lucitone 199®)和 3 种弹性衬垫(COE-SOFT™、GC RELINE™和 SOFRELINER TOUGH TOUGH®)分别浸泡在义齿清洁剂(Polident®和 Cleadent®)中 8 小时/天,在未刺激的唾液中 16 小时/天(n=25/gp),共 60 天。采用双向和三向重复测量方差分析比较表面粗糙度(Ra)、pH 值和放射性同位素结合的白色念珠菌水平(α=0.05)。采用相关分析评估 Ra 与黏附之间的关系的统计学意义。
Ra 值的降低程度依次为:COE-SOFT™、丙烯酸树脂、GC RELINE™和 SOFRELINER TOUGH®。义齿清洁剂的浸泡显著增加了弹性衬垫的 Ra 值,但 Cleadent®中的 SOFRELINER TOUGH®除外。在蒸馏水和义齿清洁剂浸泡的各组中,pH 值曲线无显著差异。白色念珠菌的结合水平依次显著降低:COE-SOFT™、GC RELINE™、SOFRELINER TOUGH®和丙烯酸树脂。Cleadent®的浸泡似乎降低了 GC RELINE™和 SOFRELINER TOUGH®上白色念珠菌的结合水平。
根据白色念珠菌结合水平的结果,不建议将 COE-SOFT™浸泡在义齿清洁剂中,GC RELINE™和 SOFRELINER TOUGH®应浸泡在 Cleadent®中。
