Pulse oximeter is a well-established and noninvasive method for measuring vascular health by evaluating oxygen saturation. This study compared the efficacy of a custom-made pulse oximeter dental probe with the electric pulp testing and thermal testing for measuring pulp vitality status of recently traumatized permanent teeth. Readings for pulp vitality for 17 recently traumatized maxillary incisors were taken with custom-made pulse oximeter dental probe (group 1), electrical pulp tester (group 2), and thermal testing (group 3) over a 6-month period. The proportion of recently traumatized teeth showing a positive responsiveness in thermal/electric pulp tests increased from no teeth showing responsiveness on day 0 to 29.4% teeth on the 28th day, 82.35% of teeth at 2 months, and 94.11% teeth at 3 months. However, pulse oximeter gave positive vitality readings that remained constant over the study period from day 0 to 6 months in all patients.
脉搏血氧仪是一种通过评估血氧饱和度来测量血管健康状况的成熟且无创的方法。本研究比较了定制的脉搏血氧仪牙科探头与牙髓电活力测试及冷热测试在测量近期外伤恒牙牙髓活力状态方面的效果。在6个月的时间里，使用定制的脉搏血氧仪牙科探头（第1组）、牙髓电活力测试仪（第2组）和冷热测试（第3组）对17颗近期外伤的上颌切牙进行牙髓活力读数。在冷热/牙髓电活力测试中显示阳性反应的近期外伤牙齿比例从第0天无牙齿有反应增加到第28天的29.4%、2个月时的82.35%和3个月时的94.11%。然而，在整个研究期间，从第0天到6个月，脉搏血氧仪给出的活力读数在所有患者中保持恒定。
