These preliminary investigations seem to indicate that the periotron may be useful in assessment of the presence of gingival inflammation in the clinical periodontal pockets. Successive recordings of the same volume varied from 5 to 11%. Data from the periotron showed a high correlation with increased known volumes of fluid and with assessment of gingival inflammation using the GI. Assessment with the periotron varied with the dissipation constant of fluids. Since the dissipation constant of gingival fluid varied among individuals, this constant must be evaluated when the instrument is used in clinical and research efforts.
这些初步研究似乎表明，牙周探测仪可能有助于评估临床牙周袋中牙龈炎症的存在情况。同一部位连续测量值的变化范围为5%至11%。牙周探测仪的数据显示，其与已知增加的液体量以及使用牙龈指数评估牙龈炎症之间存在高度相关性。使用牙周探测仪进行的评估会因液体的消散常数而有所不同。由于个体之间牙龈液的消散常数各不相同，因此在临床和研究中使用该仪器时必须评估此常数。
