Objective. To evaluate the effect of hyperbaric exposure on tooth microcirculation. Subjects and methods. The investigation enrolled 14 divers who had undergone a dental examination, followed by a study of the microcirculation of intact and carious teeth, by using laser Doppler flowmetry during simulated (pressure chamber) diving at a depth of 30 m (0.4 MPa) and 70 m (0.8 MPa). Results. In the 30- and 70-m diving groups, the baseline microcirculation of carious teeth were higher than that of intact teeth by 43.5 and 45.2%, respectively (p
