Parodontoplethysmography. A method of objective evaluation of the course of progressive scleroderma

Parodontoplethysmography was repeatedly performed in seven patients with systemic sclerosis over a period of six years. The data obtained exactly correlated to improvement or deterioration in the patients' condition. Regular parodontoplethysmography is recommended in order to observe the course of the disease more objectively. Some of the examined patients roentgenographically showed a widening of the periodontal space, a typical feature of systemic sclerosis.
