Abstract

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.

2.1 各组试件浸泡不同阶段的色差值见表1。对各组数据进行重复测量的方差分析，见表2，结果显示义齿清洁剂对材料颜色的影响有明显差异(P < 0.05)，两种材料的颜色变化有统计学差异(P < 0.05)，浸泡时间对材料颜色的影响显著(P < 0.05)。用SNK法检验每个循环阶段不同清洁剂对材料颜色影响的组间差异，结果显示：①T0-T30、T0-T60阶段：两种材料组内，Polident overnight清洁剂组与Polident partial清洁剂组、Polident overnight清洁剂组与次氯酸钠组、Polident overnight清洁剂组与清水组、Polident partial清洁剂组与Efferdent清洁剂组、Polident partial清洁剂组与次氯酸钠组、Efferdent清洁剂组与次氯酸钠组、Efferdent清洁剂组与清水组、次氯酸钠组与清水组间色差值比较差异均有显著性意义(P < 0.05)；②在T0-T90阶段：两种材料组内，Polident overnight清洁剂组与Polident partial清洁剂组、Polident overnight清洁剂组与次氯酸钠组、Polident overnight清洁剂组与清水组、Polident partial清洁剂组与Efferdent清洁剂组、Polident partial清洁剂组与次氯酸钠组、Efferdent清洁剂组与次氯酸钠组、Efferdent清洁剂组与清水组、次氯酸钠组与清水组间色差值比较差异均有显著性意义(P < 0.05)。在隐形义齿材料中，Polident overnight清洁剂组与Efferdent清洁剂组色差值比较差异均有显著性意义(P < 0.05)。用SNK法检验每种清洁剂各个循环阶段色差的组间差异，结果显示：在两种材料组内，Polident overnight清洁剂组、Polident partial清洁剂组、Efferdent清洁剂组、次氯酸钠组、清水组在T0-T30与T0-T60、T0-T60与T0-T90阶段的色差值比较均有显著性意义，说明清洁剂对材料颜色呈现持续性影响。义齿清洁剂对热凝树脂材料、隐形义齿材料颜色的影响，见图1，2。据统计学结果可知，两种材料颜色的变化随着清洁剂浸泡时间的延长而增大，各清洁剂对隐形义齿材料颜色的影响大于热凝树脂材料。不同清洁剂的影响不同，其中，1%次氯酸钠溶液对材料颜色影响最大，Efferdent、Polident overnight清洁剂对材料颜色的影响次之，但经过90次的浸泡Efferdent清洁剂对隐形义齿材料的影响大于Polident overnight清洁剂，Polident partial的作用最弱，与清水没有明显差别。"

2.2 各组试件浸泡不同阶段的表面粗糙度值见表3。对数据进行重复测量的方差分析，见表4。结果显示义齿清洁剂对材料粗糙度影响有统计学差异(P < 0.05)，两种材料的粗糙度变化显著不同(P < 0.05)，浸泡时间明显影响材料的粗糙度(P < 0.05)。用SNK法检验每个循环阶段各清洁剂对材料粗糙度影响的组间差异，结果显示：①T30阶段：两种材料组内，Polident overnight清洁剂组与次氯酸钠组、Polident overnight清洁剂组与Efferdent清洁剂组、Polident overnight清洁剂组与Polident partial清洁剂组、Polident partial清洁剂组与Efferdent清洁剂组、Polident partial清洁剂组与次氯酸钠组、Efferdent清洁剂组与清水组、次氯酸钠组与清水组粗糙度比较差异均有显著性意义(P < 0.05)；在隐形义齿材料中，Polident overnight清洁剂组与清水组、Efferdent清洁剂组与次氯酸钠组粗糙度比较差异有显著性意义(P < 0.05)；②T60、T90阶段：两种材料组内，Polident overnight清洁剂组与Polident partial清洁剂组、Polident overnight清洁剂组与Efferdent清洁剂组、Polident overnight清洁剂组与次氯酸钠组、Polident overnight清洁剂组与清水组、Polident partial清洁剂组与Efferdent清洁剂组、Polident partial清洁剂组与次氯酸钠组、Efferdent清洁剂组与次氯酸钠组、Efferdent清洁剂组与清水组、次氯酸钠组与清水组粗糙度比较差异均有显著性意义(P < 0.05)。用SNK法检验每种清洁剂各循环阶段对材料粗糙度影响差异，结果显示：①两种材料组内，Polident partial清洁剂组、清水组粗糙度在T30与T0阶段、T60与T30阶段比较差异无显著性意义，在T90与T60阶段比较差异有显著性意义，说明材料在Polident partial清洁剂和清水中长时间浸泡后粗糙度发生改变；②两种材料组内，Polident overnight清洁剂组、Efferdent清洁剂组、次氯酸钠组粗糙度在T30与T0阶段、T60与T30阶段、T90与T60阶段比较差异均有显著性意义，说明Polident overnight清洁剂、Efferdent清洁剂、次氯酸钠清洁剂对材料粗糙度呈持续性影响。"
