This study aimed to determine the effect of three commercially available denture cleansers on surface hardness of two different silicone denture liners at various time intervals.
A total of 120 cylindrical specimens of permanent silicone-based soft liners were prepared from a custom made metal mold with dimensions of 15 mm × 10 mm, of which 60 specimens were fabricated using Voco™ and the remaining 60 specimens with Molossil™ permanent denture liners. All specimens were divided into four major groups based on cleansing treatments, comprising 30 specimens each. And then, all cleansers dissolved in 250 mL water as recommended by the manufacturer. Specimens of the first group were cleansed daily by rinsing with water and second group with Periogard™ denture cleansing solution and third group with Secure™ denture cleansing solution and the fourth group with Polident™ denture cleansing solution. Specimens of all groups were tested on 1 week, 1 month, and 6 month time interval using a Shore A Durometer. Three readings were noted for each sample and the mean of those readings was taken.
Surface hardness of all the samples was significantly higher after a period of 6 months irrespective of the cleansing treatment. Statistically significant changes were observed between Polident™, Secure™, and Periogard™ denture cleanser groups over control with time. Minor changes were observed in surface hardness of Voco™ denture liners as compared to Molossil™ soft liners for all groups, as time progressed.
Voco™ soft denture lining material can be performed significantly better than Mollosil™ soft denture lining material in all cleansing treatments and Polident™ denture cleanser has the least effect on surface hardness of soft liners than Periogard™ and Secure™ denture cleansing agents.
本研究旨在确定三种市售义齿清洁剂在不同时间间隔对两种不同硅橡胶义齿衬垫表面硬度的影响。
用定制的尺寸为15毫米×10毫米的金属模具制备了总共120个圆柱形的永久性硅基软衬垫标本，其中60个标本使用Voco™制作，其余60个标本使用Molossil™永久性义齿衬垫制作。所有标本根据清洁处理分为四大组，每组30个标本。然后，按照制造商的建议将所有清洁剂溶解在250毫升水中。第一组标本每天用水冲洗进行清洁，第二组用Periogard™义齿清洁溶液清洁，第三组用Secure™义齿清洁溶液清洁，第四组用Polident™义齿清洁溶液清洁。所有组的标本在1周、1个月和6个月的时间间隔使用邵氏A硬度计进行测试。每个样品记录三个读数，并取这些读数的平均值。
无论清洁处理如何，经过6个月后所有样品的表面硬度均显著更高。随着时间的推移，与对照组相比，Polident™、Secure™和Periogard™义齿清洁剂组之间观察到统计学上的显著变化。随着时间的推移，与Molossil™软衬垫相比，所有组中Voco™义齿衬垫的表面硬度变化较小。
在所有清洁处理中，Voco™软义齿衬里材料的性能明显优于Mollosil™软义齿衬里材料，并且与Periogard™和Secure™义齿清洁剂相比，Polident™义齿清洁剂对软衬垫表面硬度的影响最小。
