The oral mucosa plays an important role in the modulation of interactions between external factors and human organism. The purpose of the study was to determine the changes in microcirculation of the oral mucosa induced by the removable dentures. Material and method. We selected 34 patients wearing partially removable dentures, with age range between 45- 75 years. For the investigation we used the photopletysmographic technique. The photopletysmography is a method which records the variations in optical density of a territory passed by blood vessels. Results: The vasomotion is disturbed by the inflammation where appears the vasodilatation which increases the blood flow. In ischemic conditions the vasomotion increases in amplitude and frequency, probably to compensate the low blood flow in the microcirculation of mucosa. Conclusions: The study showed changes in frequency and amplitude of the vasomotion. This fact denotes that the presence of traumatic dentures has a negative influence on the vascular dynamic.
