Background/Aim: Vascular supply is the most accurate measure of tooth vitality but current sensibility tests use indirect measures of subjective neural response. This study aimed to evaluate Laser Doppler Flowmetry for the assessment of pulp vitality in traumatized permanent teeth in a pediatric population. Materials and Methods: A Laser Doppler Flowmeter was used to measure blood flow in a total of 194 teeth from 51 subjects (mean age 10.1; range 6 to 16 years). Teeth were categorized into groups including revascularized (n=8), traumatized (n=85) and control (n=101). Blood flow was measured with the PeriFlux System 5000 Laser Doppler Perfusion Monitor using probe (PH 407-6) and affixed to each tooth. Tests were repeated for each erupted permanent incisor in the same arch as control. Subjects were followed to evaluate traumatized teeth for pulpal status and necrotic teeth were confirmed clinically with endodontic therapy. Results and Conclusions: Among traumatized teeth, there was no difference in pulpal blood flow based on pulp diagnosis (P=0.08). Identification of pulpal vitality in traumatized teeth is challenging. Laser Dopppler flowmetry could not distinguish necrotic from healthy pulp tissue. The technique necessitates good patient co-operation with carefully controlled conditions that preclude its use on a pediatric population.
