文题释义:
隐形义齿材料:又称弹性仿生义齿材料,1995年由美国引进中国,它采用一种以尼龙12(PA-12)为基底的高分子弹性材料制成翼状,环抱在基牙唇(颊)舌侧,韧性好,边缘封闭较严密,与传统义齿相比色泽更接近天然牙龈组织,具有更好的仿生效果和隐蔽性。
热凝聚甲基丙烯酸甲酯材料:是一种常用的义齿基托材料,具有良好的机械、理化和生物学性能,质轻,易于加工成型,易调色,被广泛应用于局部、全口活动义齿修复中。
 
 
背景:研究表明,义齿性口炎的发生和严重程度与义齿清洗方法和戴用时间有密切关系,因此研究清洁剂对义齿材料颜色、粗糙度的影响有重要意义。
目的:以浸泡法观察4种不同清洁剂对义齿材料颜色和粗糙度的影响。
方法:取热凝树脂材料、隐形义齿材料试件各25件,抛光后各分5组,分别浸泡于次氯酸钠清洁剂、Efferdent清洁剂、Polident partial清洁剂、Polident overnight清洁剂和清水中,浸泡90次,检测浸泡前及浸泡30,60,90次后的试件色差值及粗糙度。
结果与结论:①4种清洁剂对隐形义齿材料颜色、粗糙度的影响大于热凝树脂材料;②随着清洁剂浸泡时间的延长,两种材料的色差值逐渐增大;热凝树脂材料及隐形义齿材料在不同溶液中浸泡90次后,次氯酸钠清洁剂组色差值最大,然后依次为Efferdent清洁剂组、Polident overnight清洁剂组,Polident partial清洁剂组色差值最小,接近于清水组;③随着清洁剂浸泡时间的延长,两种材料的粗糙度值逐渐增大;热凝树脂材料及隐形义齿材料在不同溶液中浸泡90次后,次氯酸钠清洁剂组粗糙度值最大,然后依次为Efferdent清洁剂组、Polident overnight清洁剂组,Polident partial清洁剂组粗糙度最小,接近于清水组;④结果表明,义齿清洁剂均能引起热凝树脂材料、隐形义齿材料颜色及粗糙度的变化,次氯酸钠、Efferdent、Polident overnight清洁剂的影响较强,Polident partial清洁剂的影响较弱。

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 gradually 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.
