An experimental periodontal sensor probe (SP) equipped with an optical fiber for recording function was developed. The aim was to test the intraexaminer reproducibility of probing using the SP and to assess the consistency with the manual probe (MP).
The SP was assembled with an external sheath covering the probe tip of an MP. The sheath was slid backward by the free gingival margin while probing and the sliding distance was detected by the sensor. The probing was conducted with the walking stroke at six sites for four first molar teeth in six maintenance patients with the SP and the MP at a 1-hour interval. The deepest reading in the vicinity of each site was recorded. The measurements were rerecorded 1 week later.
The mean depth was 3.03 and 3.08 mm recorded by the MP and SP, respectively. Although no significant difference was found between the probes (P >0.05) in all measurement sites, the mean depth at the lingual site of the upper left first molar was noticeably lower with the SP. For sites ≥7 mm, significantly lower depth was recorded by the SP (P <0.05). Zero discrepancy in duplicate measurements was found in 76% of all sites with MP and 92% with SP.
The reproducibility of the SP was comparable to that of the MP. The results indicate that for sites of maintenance patients with probing depth <7 mm there was excellent agreement obtained by a single examiner using the SP compared to the MP.
研制了一种配备光纤记录功能的牙周实验传感器探头（SP）。目的是测试使用 SP 进行探测的检查者内重复性，并评估其与手动探头（MP）的一致性。
SP 由一个外部护套组装而成，护套覆盖 MP 的探头尖端。在探测时，护套通过游离龈缘向后滑动，传感器检测滑动距离。在 6 名维护患者的 4 颗第一磨牙的 6 个部位，以步行式进行探测，SP 和 MP 之间间隔 1 小时。记录每个部位附近的最深读数。1 周后重新记录测量值。
MP 和 SP 分别记录的平均深度为 3.03 和 3.08mm。虽然在所有测量部位，两种探头之间均无显著差异（P＞0.05），但 SP 记录的左上第一磨牙舌侧部位的平均深度明显较低。对于≥7mm 的部位，SP 记录的深度明显较低（P＜0.05）。在 MP 所有部位的 76%和 SP 的 92%中，重复测量的差值为零。
SP 的重复性与 MP 相当。结果表明，对于探测深度＜7mm 的维护患者部位，使用 SP 由单一检查者进行测量，与 MP 相比具有极好的一致性。
