[Changes in capillary blood flow in the gingiva during emotional excitation].

In 30 subjects aged 20 to 44 years the functional changes were studied in the gingival capillary bed, pulse rate, systolic and diastolic blood pressure before and during emotional excitation. These values compared, considerable effects were detected suggesting the general circulatory changes and substantial reduction of gingival microcirculation. This indicated that emotional stress-inducing factors may lead to periodontal diseases.
