MICROVASCULAR CHARACTERISTICS OF THE HUMAN INTERDENTAL PAPILLA.

The aim of this study was to observe the microcirculation characteristics of the human interdental papilla in healthy patients in vivo. Twenty healthy patients were examined. Capillaroscopy was used to investigate the characteristics of microcirculation of the human periodontal mucosa. Visibility, course, tortuosity, as well as the average caliber of the capillary loops and the number of visible capillary loops per square millimeter were evaluated for each patient. The investigation of gingival mucosa revealed capillary loops with a course both parallel and perpendicular to the surface. Our study has pointed out that capillaroscopy is a reliable method to study periodontal microcirculation in vivo. This method could be applied to the study of microcirculation in periodontal diseases. Future studies might evaluate whether microcirculation in that area is compromised or not during systemic pathologies involving peripheral microcirculation alterations
