义齿清洁剂对热凝树脂材料、隐形义齿材料颜色和粗糙度的影响
Effects of denture cleansers on color stability and surface roughness of heat-curing denture base resins and elastic denture base materials
摘要
Abstract
BACKGROUND:The occurrence and severity of denture stomatitis are closely related to denture cleaning methods and wearing time. Therefore, it is of great significance to explore the effects of denture cleansers on denture surface roughness and color stability.OBJECTIVE:To investigate the effects of four different denture cleansers on the surface roughness and color stability of heat-curing denture base resins and elastic denture base materials by means of soaking test.METHODS: Samples of heat-curing denture base resins (n=25) and elastic denture base materials (n=25) were polished and soaked in NaClO, Efferdent, Polident partial, Polident overnight and water, respectively. The soak process was repeated 90 times. Then the color aberration and surface roughness were tested using color meter and roughmeter before soaking and after 30, 60, 90 times of soaking.RESULTS AND CONCLUSION:These four kinds of denture cleansers have greater influence on the elastic denture base materials than on the heat-curing denture base resins. With the increasing of soaking time, the color aberration and surface roughness of the two kinds of denture materials were increased gradualy after treatment with different denture cleansers, and the values were ranked as follows: NaClO > Efferdent > Polident overnight > Polident partial and water. To conclude, denture cleansers can induce the changes in denture surface roughness and color stability of heat-curing denture base resins and elastic denture base materials. NaClO exerts the strongest effect, followed by Efferdent and Polident overnight, and Polident partial exhibits the weakest effect.关键词
