Tissue conditioners are used to improve the health of the soft tissues of denture-bearing areas. However, leaching of plasticizers from tissue conditioners results in deterioration, which necessitates frequent replacement. The life of these liners varies, but it can be extended by the use of a coating material.
To evaluate the surface roughness of a tissue conditioner with monopoly coating, subjected to denture cleanser and disinfectant.
Sixty disk-shaped specimens of Visco-gel were made and divided into six groups of 10 each (control 1 [C1], control 2 [C2], control 3 [C3], group 1 [M1], group 2 [M2], and group 3 [M3]). Specimens of the control group were not coated with monopoly, while the specimens of the groups 1, 2, and 3 were coated with monopoly. Specimens of C1 and M1 were immersed in distilled water. Specimens of C2, C3, M2, and M3 were immersed into solution of denture cleanser for 8 h at room temperature and immersed in distilled water for the remainder of the 24-h period. C3 and M3 specimens were treated with disinfectant for 10 min before testing the surface roughness. The surface roughness was measured on 1, 3, 5, 7, and 14 day, using a contact profilometer. Student's paired -test was used to compare the mean Ra values within each group. In the present study, < 0.05 was considered as the level of significance.
The mean surface roughness values of M1, M2, and M3 groups were less than C1, C2, and C3, respectively. Among all the groups, M1 showed the least surface roughness values.
Monopoly-coating agent prevents the deterioration and reduces the surface roughness of the tissue conditioner.
组织调理剂用于改善义齿承托区软组织的健康状况。然而，组织调理剂中的增塑剂渗出会导致其性能恶化，这就需要频繁更换。这些衬垫的使用寿命各不相同，但可以通过使用涂层材料来延长。
评估涂有专利涂层的组织调理剂在假牙清洁剂和消毒剂作用下的表面粗糙度。
制作60个圆盘状的Visco - gel样本，并将其分为六组，每组10个（对照组1 [C1]、对照组2 [C2]、对照组3 [C3]、第1组 [M1]、第2组 [M2] 和第3组 [M3]）。对照组的样本未涂专利涂层，而第1、2、3组的样本涂有专利涂层。C1和M1组的样本浸泡在蒸馏水中。C2、C3、M2和M3组的样本在室温下浸泡在假牙清洁剂溶液中8小时，在24小时的剩余时间里浸泡在蒸馏水中。C3和M3组的样本在测试表面粗糙度之前用消毒剂处理10分钟。使用接触式轮廓仪在第1、3、5、7和14天测量表面粗糙度。采用学生配对t检验比较每组内的平均Ra值。在本研究中，P < 0.05被视为显著性水平。
M1、M2和M3组的平均表面粗糙度值分别低于C1、C2和C3组。在所有组中，M1组的表面粗糙度值最小。
专利涂层剂可防止组织调理剂性能恶化并降低其表面粗糙度。
