Background: A major drawback of traditional pulp testing procedures is that they depend on neural responses rather than vascular circulation. Hence, this study aimed to develop a custom-modified dental sensor using a finger pulse oximeter (PO) that is applicable to any type of tooth so as to test its ability and accuracy in evaluating the oxygen saturation (SaO2) values of teeth at different developmental stages as a measure of pulp vitality.
Materials and methods: A customized finger PO was employed to determine the systemic and pulp SaO2 levels in 300 children. A total of 600 teeth (primary and permanent) were divided into group I (100 primary molars), group II (200 permanent molars), group III (200 permanent incisors), and 100 endodontically treated (primary and permanent) teeth were included in group IV. The mean SaO2 values thus obtained in various groups were compared.
Results: Intragroup comparison of mean SaO2% of the patient's finger (systemic), test teeth, and control teeth showed significant differences (p ≤ 0.001). Intergroup comparisons also revealed significant differences in most of the groups.
Conclusions: The modified PO probe can be applied to any type of tooth. It was found to be accurate and sensitive enough to detect changes in SaO2 levels in various clinical situations irrespective of developmental stage. It proved to be a direct method of evaluation of pulp vitality by objective means.
