The technology of pulse oximetry has allowed significant advances in the medical field yet its use in dentistry has been virtually unexplored. This study investigates the potential of the pulse oximeter to detect vascular integrity within the human tooth. Forty-nine young adults were evaluated for the vitality of their maxillary central incisors utilizing thermal, electrical, and oximetric techniques. The pulse oximeter was found to indicate a pulse rate and oxygen saturation reading for the vital teeth and no readings for the teeth previously endodontically treated. The accuracy of this diagnostic method supports the need for additional study in the use of the pulse oximeter to interpret the pathological processes of the pulp.
脉搏血氧测定技术在医学领域取得了重大进展，但其在牙科的应用实际上尚未得到探索。本研究调查了脉搏血氧仪检测人牙齿内血管完整性的潜力。利用热、电和血氧测定技术对49名年轻成年人的上颌中切牙活力进行了评估。结果发现，脉搏血氧仪能显示活牙的脉搏率和血氧饱和度读数，而先前接受过根管治疗的牙齿则无读数。这种诊断方法的准确性支持了进一步研究脉搏血氧仪在牙髓病理过程解释中的应用的必要性。
