摘要

目的:本研究旨在确定乳胶和非乳胶弹性带在使用时间和唾液pH浓度的基础上的力衰减差异。材料与方法:本研究的样本量计算采用费德勒。总样本量为80,分为四组。第一组由浸泡在pH为5.2的人工唾液中的乳胶制成的20条橡皮筋组成,第二组由浸泡在pH为6.7的人工唾液中的乳胶制成的20条橡皮筋组成,第三组由浸泡在pH为5.2的人工唾液中的非乳胶制成的20条橡皮筋组成,第四组由浸泡在pH为6.7的人工唾液中的非乳胶橡皮筋组成。所有样品在37°C下孵育,用数字力计测量力的大小。结果:人工唾液浸泡后24小时内力衰减最明显,并持续72小时。与pH值6.7相比,胶乳和非胶乳的弹性带在唾液pH浓度下均表现出更大的力衰减。结论:胶乳和非胶乳弹性带在弹性使用时间上的力衰减有显著差异。非乳胶弹性带的力衰减大于乳胶弹性带。根据唾液的pH值,乳胶和非乳胶制成的弹性带在力衰减方面存在差异。由非乳胶材料制成的力衰减弹性带比乳胶材料大,在pH值为5.2时比在pH值为6.7时更大。

Difference in force decay latex and non-latex elastic band based on duration of elastic use and salivary pH concentration: In vitro study.

Objective: This study aimed to determine the difference in force decay between latex and non-latex elastic bands based on duration of use and salivary pH concentration.

Material and method: The calculation of the sample size in this study used Federer. Total sample size is 80 and divided into four groups. First group consists of 20 elastic bands made from latex immersed in artificial saliva pH 5.2, second group consists of 20 elastic bands made from latex immersed in artificial saliva pH 6.7, third group consists of 20 elastic bands made from non-latex immersed in artificial saliva pH 5.2, and fourth group consists of 20 non-latex elastic bands immersed in artificial saliva pH 6.7. All samples were incubated at 37°C, and force magnitude was measured with a digital force gauge.

Results: The most force decay occurred in the first 24 hours when immersed in artificial saliva and was constant for up to 72 hours. The elastic band immersed in salivary pH concentration showed greater force decay compared with pH 6.7 both latex and non-latex.

Conclusion: There was a significant difference in force decay of elastic bands made from latex and non-latex based on duration of elastic use. Force decay of elastic bands made from non-latex was greater than latex material. There was a difference in force decay elastic bands made from latex and non-latex based on the pH concentration of saliva. Force decay elastic band made from non-latex is greater than latex material and greater at pH 5.2 compared to 6.7.
