One of the most important steps in deciding on the treatment of a tooth is to determine the vitality and health status of the pulp. Since immature teeth innervation is not completed, the response to sensitivity tests may not yield definite results. Pulse oximetry (PO) which is considered as a vitality test, measures the arterial oxygen saturation (SpO). This study aims to compare PO, electric pulp test (EPT) and cold test in mature and immature permanent teeth.
20 immature and 20 mature permanent incisors of 6-12-year-old ASA1 children who did not use any analgesics, were included in the study. Pulp vitality of the teeth was determined by EPT, cold test and PO. An infant probe of PO device (CMS60D, Contec Medical Systems Co. Ltd, China) was used to determine the SpO of the teeth. The SpO level is controlled on the patient's finger by a children's probe and an infant probe of PO. Shapiro-Wilk, Spearman rank correlation test and Kruskal-Wallis test/Dunn post-hoc analysis were used for statistical comparisons.
There was no significant correlation between finger SpO and the mature/immature teeth SpO (r=-0.026, r = 0.253). Arterial oxygen saturation values in the immature teeth were significantly higher than in the mature teeth (p = 0.002). There was a high correlation between the vitality response of the EPT, cold test and PO.
Pulse oximetry can be used as an effective vitality test compared to sensitivity tests in both immature and mature permanent incisors.
决定牙齿治疗方案最重要的步骤之一是确定牙髓的活力和健康状况。由于未成熟牙齿的神经支配尚未完成，对敏感测试的反应可能无法得出明确的结果。脉搏血氧饱和度仪（PO）被认为是一种活力测试，测量动脉血氧饱和度（SpO）。本研究旨在比较 PO、电活力测试（EPT）和冷测试在成熟和未成熟恒牙中的应用。
选择 6-12 岁 ASA1 级、未使用任何镇痛药的 20 颗未成熟恒牙和 20 颗成熟恒牙。通过 EPT、冷测试和 PO 确定牙齿的牙髓活力。使用 PO 设备（CMS60D，Contec Medical Systems Co. Ltd，中国）的婴儿探头来确定牙齿的 SpO。通过儿童探头和 PO 的婴儿探头控制 SpO 水平在患者手指上。使用 Shapiro-Wilk、Spearman 秩相关检验和 Kruskal-Wallis 检验/Dunn 事后分析进行统计比较。
手指 SpO 与成熟/未成熟牙齿 SpO 之间无显著相关性（r=-0.026，r=0.253）。未成熟牙齿的动脉血氧饱和度值明显高于成熟牙齿（p=0.002）。EPT、冷测试和 PO 的活力反应之间存在高度相关性。
与敏感测试相比，脉搏血氧饱和度仪可作为一种有效的活力测试，可用于成熟和未成熟恒牙。
