Periotest测量牙周组织对确定的膨胀力的反应。通过电子控制的敲击头对齿进行敲击。通过测量牙周组织的弹性和粘性特性，获得关于结构变化的信息。后者防止牙齿在牙槽骨中的振荡。计算值并显示为“Periotest值”。以下研究报告显示了Periotest值与骨丢失的关系。骨丢失定量测定2312牙齿orthopantomographic射线照片和900牙齿暴露于口内片使用标准的平行技术。对垂直和水平骨丢失进行了区分。临床活动指数，袋深度，牙龈退缩和乳头出血指数也进行了测量。Periotest值与骨丢失之间存在强相关性。这些结果表明，Periotest评价提供了牙周骨丢失程度的客观指标。
The Periotest measures the reaction of the periodontium to a defined percussive force. The percussion is applied to the tooth by an electronically controlled tapping head. Information on structural change is obtained by measurement of both the elastic and viscous characteristics of the periodontium. The latter prevent oscillations of the tooth in the alveolar bone. A value is calculated and is displayed as a "Periotest value". The following research report shows the relation of Periotest values to bone loss. Bone loss was quantitatively determined for 2312 teeth from orthopantomographic radiographs and for 900 teeth exposed to intra-oral films using the standard paralleling technique. A differentiation was made between vertical and horizontal bone loss. Clinical mobility index, pocket depth, gingival recession and papillary hemorrhagic index were also measured. There was a strong association between the Periotest value and bone loss. These results suggest that Periotest evaluation provides an objective indication of the extent of periodontal bone loss.
