Maintaining the oral hygiene of denture wearers is a challenge faced in modern dentistry. Biofilm formed on dentures has been associated with denture stomatitis, malodor, aspiration pneumonia, infectious endocarditis, gastrointestinal infection, and chronic obstructive pulmonary disease.
The purpose of this study was to evaluate the effect of denture cleansers on the surface roughness of hard denture base material.
A total of 100 heat-cure acrylic resin specimens were fabricated with dimensions 30 mm × 15 mm × 3 mm in length, width, and thickness, respectively. All specimens were distributed into four groups randomly. Three commonly prescribed denture cleansers were used for immersion in this study. Regular tap water was used for immersion in the control group. Surface roughness was determined before immersion and after immersion in denture cleansing solutions using contact profilometer. The data were subjected to statistical analysis using paired t-test, one-way analysis of variance, and Tukey's multiple post hoc test.
The change in surface roughness of acrylic samples immersed in Clanden group was statistically significant (P < 0.05) at individual group level. However, the change in surface roughness of acrylic samples after immersion, when compared between the groups, namely, control, Clinsodent, Clanden, and Fittydent, was not statistically significant (P > 0.05).
Within the limitation of this study, the three denture cleansing materials, namely, Clinsodent powder, Clanden tablet, and Fittydent tablet, are safe to be prescribed as denture cleansers.
保持假牙佩戴者的口腔卫生是现代牙科面临的一项挑战。假牙上形成的生物膜与假牙性口炎、口臭、吸入性肺炎、感染性心内膜炎、胃肠道感染和慢性阻塞性肺疾病有关。
本研究的目的是评估假牙清洁剂对硬质假牙基托材料表面粗糙度的影响。
共制作100个热固化丙烯酸树脂标本，其长度、宽度和厚度分别为30 mm×15 mm×3 mm。所有标本随机分为四组。本研究使用三种常用的处方假牙清洁剂进行浸泡。对照组使用普通自来水进行浸泡。使用接触式轮廓仪在浸泡于假牙清洁溶液之前和之后测定表面粗糙度。数据采用配对t检验、单因素方差分析和Tukey多重事后检验进行统计分析。
在个体组水平上，浸泡在Clanden组中的丙烯酸样品表面粗糙度变化具有统计学意义（P < 0.05）。然而，在对照组、Clinsodent、Clanden和Fittydent组之间比较时，浸泡后丙烯酸样品的表面粗糙度变化无统计学意义（P > 0.05）。
在本研究的局限性内，三种假牙清洁材料，即Clinsodent粉末、Clanden片剂和Fittydent片剂，作为假牙清洁剂开处方是安全的。
