牙齿松动是牙周病的一个主要症状,导致牙齿松动的原因很多,如牙槽骨吸收、牙周组织炎症、咬合创伤等,松动度的改变是评价牙周病治疗效果的重要指标之一,但在目前的临床检查中,牙齿松动度的测量仅仅靠检查者的肉眼观察,由于观察角度及手法不同,测量结果可能出现较大的误差,牙周测试仪(Perwtest)可弥补这一不足,它能客观地评价牙齿的松动度,且以数字形式表现出来.牙周测试仪(Perwtest)的值是衡量牙周健康状况的可重复的,定量的单位,就象血压值一样,是一个生理的参数,(Perwtest)值并不完全是牙齿活动度的测量结果,但与牙齿松动度紧密相关,本文通过对100例正常人5+55+5牙和19例牙周病患者的317个牙的洁治与根面平整前、后的牙周测试仪(Perwtest)值(以下简称牙周测定值)的变化来探讨正常牙的牙周测定值范围与国外正常值范围的比较以及牙周洁治及根面平整后由于炎症消退后而引起牙齿松动度变化在牙周测定值上的反应,为今后的牙周病治疗工作提供参考.
Dental loosening is one of the main symptoms of periodontal disease, leading to loose teeth for many reasons, such as alveolar bone resorption, periodontal tissue inflammation, occlusal trauma, changes in mobility is to evaluate the effect of one of the important indicators of periodontal disease treatment, However, in the current clinical examination, the measurement of tooth loosening is only based on the naked eye of the examiner. Due to different observation angles and methods, the measurement result may have a large error. The Perwtest can make up for the deficiency, It evaluates the degree of tooth loosening objectively and in digital form. The Perwtest value is a repeatable, quantitative measure of periodontal health, just like a blood pressure value, (Perwtest) value is not entirely the result of measurement of tooth mobility, but it is closely related to the degree of tooth mobility. In this paper, 317 teeth of 100 + 5 + 55 + 5 teeth and 19 patients with periodontal disease And the Perwtest value (hereinafter referred to as the periodontal value) before and after root-mean-square measurement were used to investigate the comparison between the periodontal value range of normal tooth and the foreign normal range, Root level flat After the whole after the inflammation subsided caused by changes in the degree of tooth mobility in periodontal measurements of the response for the treatment of periodontal disease in the future to provide a reference.
