ABSTRACT

Basing on rheo- and photoplethysmography combined with mathematical methods and computers the authors have developed a method for the differential diagnosis of periodontal diseases (gingivitis, periodontitis). Diagnostic studies carried out in 200 patients have shown a high probability (at least 92 percent) of the method for the differential diagnosis of periodontal diseases.

ABSTRACT

In 120 patients the periodontal photoplethysmography was performed. Statistical analysis of the frequency-amplitude characteristics of the photoplethysmographic signal was useful for differential diagnosis of various forms and stages in periodontal diseases and for evaluation of the treatment efficiency.
