Abstract

Aim: The aim of this study was to compare the measurement of periodontal pocket by ultrasound in comparison with gold standard measurements ex-vivo.

Material and methods: A total of 12 hemi-jaws were included in the study. Ultrasound measurements of the sulcus were performed and then, sulcus depth was measured by manual probing. The reading of the ultrasound images was carried using ImageJ software. Reference points are made allowing the measurement of this sulcular space. To assess the hypothesis of normality of the data, a Kolmogorov-Smirnov test was performed for each of the samples due to the size of their population (>50). To complete this test, Lin's concordance test was also applied.

Results: A total of 348 manual probing and 348 ultrasound imagines measurements were performed. The Lin concordance and correlation coefficients and their 95% confidence intervals obtained were 0.855 (95% CI [0.822; 0.855]). These data allow us to demonstrate the equivalence between the measurement of the depth of the periodontal pocket by ultrasound imaging and the measurement by manual probing.

Conclusion: This study shows that the use of an ultrasound probe for periodontal imaging was comparable to the current gold standard for measuring the sulcus area. These promising results must be confirmed by measurements in humans.

离体高频超声成像测量沟:一项探索性研究。
目的:比较超声测量牙周袋与离体金标准测量牙周袋的差异。材料与方法:本研究共采用12个半颌。超声测量沟,然后用手探测沟的深度。采用ImageJ软件进行超声图像读取。参考点是允许测量这个管状空间。为了评估数据的正态性假设,由于每个样本的总体大小(bbb50),对每个样本进行Kolmogorov-Smirnov检验。为了完成这个测试,我们还使用了Lin的一致性测试。结果:共进行手工探查348次,超声图像测量348次。Lin一致性和相关系数及其95%可信区间为0.855 (95% CI [0.822;0.855])。这些数据使我们能够证明超声成像测量牙周袋深度与人工探探测量牙周袋深度之间的等效性。结论:本研究表明,使用超声探头进行牙周成像与目前测量牙沟面积的金标准相当。这些有希望的结果必须通过人体测量来证实。
