The suitability of bleeding provocation in the gingival sulcus in dependence on the probing pressure is examined as an early sign of gingivitis. In preliminary tests it has been found that the individual exertion in probing is varying strongly between the examiners but the intraindivudual force application varies only slightly. During the force application of 0.3 N or 0.6 N corresponding to a inflammatory signs of colour and form change of the gingiva. The symptoms had been classified into SBI, PBI and GI indices. With a probing force of 0.3 N considerably less gingival units are diagnosed diseased than by determination of colour and form change. Only with increased force application of 0.6 N corresponding to a pressure of 227 N/cm2 the bleeding symptom represents an early diagnostic sign. To determine the therapeutical success by an examiner the correlations of bleeding reductions are maintained.
研究牙龈沟内出血激发试验的适宜性与探诊压力的关系，作为牙龈炎的早期迹象。在初步试验中发现，不同检查者在探诊时的个体用力差异很大，但个体内部的用力情况变化很小。在施加0.3 N或0.6 N的力时，牙龈出现颜色和形态改变等炎症迹象。症状已根据龈沟出血指数（SBI）、探诊后出血指数（PBI）和牙龈指数（GI）进行分类。与通过颜色和形态改变确定相比，使用0.3 N的探诊力诊断出的患病牙龈单位要少得多。只有在增加到0.6 N的力（相当于227 N/cm²的压力）时，出血症状才代表早期诊断迹象。为了让检查者确定治疗效果，需保持出血减少情况的相关性。
