[Dependence of bleeding provocation on the probing force for diagnostics and progress evaluation of inflammatory...

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.
