21 autotransplanted teeth were examined by using laser Doppler flowmetry (LDF) at 1, 2, 3, 6 and 12 postoperative weeks. 20 teeth showed statistically significantly higher perfusion units up to the 6th weeks as compared to the control group. At 12 postoperative weeks, the perfusion values of the autotransplanted teeth were at the same level as those of the control group. It was possible to show a non-revascularisation of one tooth with LDF. Currently, LDF can be considered as the only practicable, non-invasive method to evaluate the revascularization of autotransplanted teeth.
