[The microcirculation in periodontal tissues: 2. The action of the regular use of chewing gum]

The effect of regular use of chewing gum (for 28 days) on microcirculation was assessed in 35 patients with slight and medium-severe periodontitis by biomicroscopy and laser Doppler flowmetry. Microcirculation normalized immediately after chewing training due to arrest of arteriolar spasm. In slight periodontitis the effect persists for almost one year, in medium-severe condition for up to 6 months, because of more expressed structural changes in the microvessels of periodontal tissue.
