Smoking habit is an important risk factor in oral diseases. In the last years, many studies triedto evaluate smoking effects on the microcirculation. It had never been used such a simple not invasivetechnique, like the video-capillaroscopic one. The aim of the research is to analyse “in vivo”, themicrocirculation labial characteristics, and to evaluate the smoking effects by means of computerisedvideocapillaroscopy techniques.35 healthy no-smoker patients and 35 healthy smoker patients were examined. The characteristicsof the microcirculation in the areas of labial mucous were examined using computerised videomicroscopictechniques. For each patient we evaluated the visibility, the course, the tortuosity andany images characteristic of capillary loops, besides the possible presence of microhaemorrhages, theaverage calibre of capillary loops and the number of capillary loops visible per square millimetre.The investigation was non invasive and repeatable for each patient. In both groups the investigationof labial mucous revealed a course of capillary loops parallel to the surface.In smoker patients, it was possible to underline capillaries of a smaller calibre (P<.001), and ahigher number of detectable capillaries compared with no-smoker patients (P<.001). We observedan important correlation between the capillary tortuosity and the smoking habit (P<.001).Our research highlighted, that today it is possible to carry out a capillaroscopic investigationof labial mucous in a simple and reliable way. Furthermore, smoking habit represents a real risk factorof oral disease, greatly affecting the microcirculation.
