Over 25,000 sites around natural teeth in three stages of periodontal therapy (prior to instrumentation, following closed subgingival instrumentation and following surgical therapy) were independently probed by two examiners. Examiner A used a conventional periodontal probe with uncontrolled pressure. Examiner B used an identical probe tip mounted in a handle which controlled vertical probing force at 50 g. The pressure-controlled technique produced significantly deeper clinical probing measurements on the direct facial and lingual aspects of teeth regardless of the stage of periodontal therapy that had been completed. Manual probing obtained deeper measurements on the distal-lingual aspects of teeth in the posterior regions which had not received surgical therapy. The percentage match between probing depths obtained by the two methods declined as the probing depths increased. Control of vertical force during probing may provide a more objective method of monitoring periodontal status during longitudinal trials.
在牙周治疗的三个阶段（器械治疗前、龈下封闭器械治疗后和手术治疗后），由两名检查者对天然牙周围超过25000个位点进行独立探测。检查者A使用传统牙周探针，施加压力不受控制。检查者B使用安装在手柄中的相同探针尖端，将垂直探测力控制在50克。无论牙周治疗已完成的阶段如何，压力控制技术在牙齿的直接唇面和舌面产生的临床探测深度明显更深。在未接受手术治疗的后部区域，手动探测在牙齿的远中舌面获得的深度测量值更深。两种方法获得的探测深度之间的匹配百分比随着探测深度的增加而下降。探测过程中垂直力的控制可能为纵向试验期间监测牙周状况提供一种更客观的方法。
