To evaluate the hardness, roughness and color stability of artificial teeth after immersion in liquid disinfectant soaps.
Artificial teeth (Vipi Dent Plus, ArtiPlus and Biolux) were divided into four groups (n=15), according to the type of immersion solution: distilled water/control group (DW); liquid disinfectant soap Dettol (SD); liquid disinfectant soap Protex (SP); and liquid disinfectant soap Lifebuoy (SL). The immersion cycles occurred every day, for 8 hours at room temperature in each disinfectant solution, following immersion in distilled water for 16 hours at 37°C. All solutions were changed daily. Properties were evaluated after 0, 7, 14, 21 and 28 days of immersion. The data were analyzed with a mixed three-way ANOVA followed by the Bonferroni post-hoc test (α= 0.05).
Vipi teeth presented significant reduction (P< 0.05) in hardness and roughness prior to 7 days of immersion in all solutions, including control group. These values, in general, were maintained during the 28 days. Biolux teeth, in general, did not present significant changes in hardness prior to immersion in any of the time intervals. The roughness of these teeth increased after 21 and 28 days of immersion (P< 0.05) in all the solutions. ArtiPlus teeth maintained stable roughness and hardness during the assessment period, regardless of the type of soap used. Color alterations were considered clinically acceptable. The liquid soaps may be an alternative for the disinfection of partial or total removable dentures.
The liquid disinfectant soaps tested did not significantly alter the hardness, roughness and color stability of the artificial teeth tested and may be an alternative for the disinfection of partial or total removable dentures.
评估人工牙浸泡在液体消毒皂液后其硬度、粗糙度和颜色稳定性。
根据浸泡溶液类型，将人工牙（Vipi Dent Plus、ArtiPlus和Biolux）分为四组（n = 15）：蒸馏水/对照组（DW）；滴露液体消毒皂（SD）；保宁液体消毒皂（SP）；力士液体消毒皂（SL）。每天进行浸泡循环，在室温下于每种消毒溶液中浸泡8小时，之后在37°C下于蒸馏水中浸泡16小时。所有溶液每天更换。在浸泡0、7、14、21和28天后评估各项性能。数据采用混合三因素方差分析，随后进行Bonferroni事后检验（α = 0.05）。
在所有溶液（包括对照组）中浸泡7天之前，Vipi牙的硬度和粗糙度显著降低（P < 0.05）。总体而言，这些值在28天内保持稳定。一般来说，Biolux牙在任何时间间隔浸泡之前，硬度均未出现显著变化。在所有溶液中浸泡21天和28天后，这些牙的粗糙度增加（P < 0.05）。无论使用何种肥皂类型，ArtiPlus牙在评估期间保持粗糙度和硬度稳定。颜色变化在临床上被认为是可接受的。液体肥皂可作为部分或全口可摘义齿消毒的一种替代方法。
所测试的液体消毒皂未显著改变所测试人工牙的硬度、粗糙度和颜色稳定性，可作为部分或全口可摘义齿消毒的一种替代方法。
