Pulse oximetry is an equipment that evaluates pulp vitality for concrete endodontic diagnosis and treatment plan. One of the treatment methods of oropharyngeal cancer is radiotherapy. Radiotherapy has some harmful effects on dental pulp that affects pulp vitality. The objective of study was to assess pulp vitality before, at the end of radiotherapy and six months after radiotherapy (RT) in oropharyngeal cancer patients undergoing radiotherapy. 25 patients who were diagnosed with oropharyngeal cancer having asymptomatic intact crowns were selected for the study. Pulp vitality was checked before the commencement of radiotherapy (PV1), immediately after radiotherapy (PV 2) and six months post radiotherapy (PV 3). Pulp vitality of first posterior tooth was selected of each patient and was checked with pulse oximetry. Paired t-test was used as statistical analysis. Statistically significant difference was observed when PV 1 and PV 2, PV 1 and PV 3 and PV 2 and PV 3 were compared amongst each other. There was reduction noted in mean SpO2 value when groups PV 2 and PV1 were compared. This was statistically significant. Statistically significant increase in mean SpO2 value was observed six months post radiotherapy (PV 3). Thus, it can be concluded that statistically significant reduction in mean SpO2 level post radiotherapy recovers after six months.
脉搏血氧测定法是一种用于评估牙髓活力以制定具体牙髓病诊断和治疗方案的设备。口咽癌的治疗方法之一是放射治疗。放射治疗对牙髓有一些有害影响，会影响牙髓活力。本研究的目的是评估接受放射治疗的口咽癌患者在放疗前、放疗结束时以及放疗后六个月的牙髓活力。选择25例被诊断为口咽癌且牙冠完整无症状的患者进行研究。在放疗开始前（PV1）、放疗结束后立即（PV2）以及放疗后六个月（PV3）检查牙髓活力。选取每位患者的第一颗后牙，用脉搏血氧测定法检查牙髓活力。采用配对t检验进行统计分析。在比较PV1与PV2、PV1与PV3以及PV2与PV3时，观察到有统计学意义的差异。比较PV2和PV1组时，平均SpO2值有所降低，这具有统计学意义。放疗后六个月（PV3）观察到平均SpO2值有统计学意义的升高。因此，可以得出结论，放疗后平均SpO2水平有统计学意义的降低在六个月后恢复。
