对100例上颌中门牙和侧门牙正常的儿童分别进行了电血氧仪和脉搏血氧仪的活力测试。作为确认读数的对照人群，对10颗已知的具有完整根管充填物的非重要前牙进行了测试。以患者食指测量的全身血氧饱和度值作为对照，与牙齿测量的血氧饱和度值进行比较。牙齿上获得的SaO2值与电测试读数相关。SaO2读数与电测试读数之间呈负相关，即随着电浆测试读数的增加，SaO2值降低。由于可以在重要牙齿上获得可重复的SaO2水平，因此脉搏血氧仪在为创伤牙齿提供基线活力数据方面具有直接的临床价值。
One hundred children with normal maxillary central and lateral incisors were subjected to vitality tests each by electrical and pulse oximetry. As a control population to confirm the readings, 10 known nonvital anterior teeth with complete endodontic fillings were tested. The systemic oxygen saturation values measured on the index finger of the patient served as the control for the comparison of the oxygen saturation values measure on the teeth. The SaO2 values obtained on the teeth were correlated with the electrical test readings. The correlation between the SaO2 readings and electrical testing readings were found to be negative i.e. as the values of the electrical pulp testing reading increased, the SaO2 values decreased. Since a reproducible SaO2 level is obtainable on the vital teeth, pulse oximetry has immediate clinical value in providing base line vitality data for the traumatised teeth.
