Smoking appears to be one of the most significant risk factors in the development and progression of periodontal disease. Smoking is also a risk factor in the development of peripheral vascular diseases. Blood vessels in smokers are fewer and are subjected to stenosis. ⋯ In 30 minutes we observed a marked decrease in gingival blood flow in all groups, followed by gradual restoration of blood flow rate, registered before smoking. This restoration took 1.5-2 hrs in group with light periodontitis, 2 hrs in group with moderate periodontitis and more than 2 hrs in group with heavy periodontitis. We suppose, that constant changes in blood supply of periodontal tissue caused by smoking may contribute to higher prevalence and faster progression of inflammatory periodontal diseases in smokers.
