“…That result could be explained by the fact that the oxygen saturation was measured only in the maxillary anterior teeth, while in our study, measurements were taken from all maxillary teeth. Sharma et al found a strong positive relationship between the tooth and finger oxygen saturation values in the vital permanent teeth [31]. Although the age of the patients in their study was from 4 to 12 years old, no data regarding the root formation stage was specified.…”

Background and Objectives An accurate determination of the pulp status is relevant for a proper endodontic diagnosis. Objectives: The aim was to develop a universal pulse oximeter probe holder for measuring the oxygen saturation and to evaluate the use of pulse oximetry as a test for pulp vitality, by comparing the levels of oxygen saturation in the index finger and in the healthy dental pulp. Materials and Methods The universal holder was designed with software and printed with a 3D printer. The study was carried out on 128 healthy teeth. They were divided into eight groups according to tooth type. Ten root canal treated teeth served as a negative control group. For each patient, a pulse oximeter was first applied on the tooth followed by the index finger. The significance level (α) was set at 0.05. Results: The developed and manufactured universal pulse oximeter probe holder was suitable to measure the pulp vitality of all types of teeth. The handle allowed for holding the pulse oximeter on the tooth in parallel, firmly and securely. Significantly higher oxygen saturation was observed in the index finger (97.22%) compared to the dental pulp (93.17%) (p < 0.001). No correlation was observed between the maxillary teeth and index finger oxygen saturation values (r = 0.05, p = 0.72), whereas, between the mandibular teeth and index finger, a positive correlation was detected (r = 0.29, p = 0.02). There were no significant differences in the pulp oxygen saturation values between different teeth groups. Conclusion: The newly developed universal pulse oximeter probe holder is an effective device for pulp vitality testing.

“…Sharma et al showed that thermal pulp test and pulse oximetry accuracy was 100% and this was 90% in electrical pulp test for permanent and 86.67% for primary teeth. 17 In a study by Dastmalchi et al 18 on 24 mature mandibular premolars, the sensitivity of pulse oximeter, cold test, and EPT was 93%, 53%, and 60%, respectively. Their specificity was 100%, 55%, and 22%, respectively.…”

“…Most previous studies have focused on sensitivity and specificity of tests, but PPV and NPV are also important for clinical use of a diagnostic test. 8,15,17 In the assessment of these values, the prevalence of the disease is important because these values change with prevalence. 13 The prevalence was 52% in the study by Gopikrishna et al 6 , 39% in the study by Peterson et al 26 , and 25% in our study.…”

“…In previous studies, this value was reported to be in the range of 92% to 100% for pulse oximeter, which was higher than the value for the cold test and EPT; however, the values for the cold test and EPT have been widely variable in different studies. 2,6,8,12,17,24,25 The discrepancy in the results of studies may be attributed to different methodologies, control of confounding factors, sample size, type of tooth, and age of patients. Patient's age is an important factor affecting the results.…”

Introduction: Pulp sensitivity tests are commonly used for assessment of pulp vitality. However, indirect assessment of pulp vitality by evaluation of nerve response and subjective nature are the main limitations of these tests. Pulse oximetry is used for assessment of blood oxygen saturation in medicine, and its efficacy for assessment of pulp vitality needs to be evaluated. Aim: This study aimed to assess and compare the efficacy of pulse oximeter with a modified probe, cold test, and electric pulp test for evaluation of pulp vitality in permanent immature teeth. Materials and methods: This cross-sectional study was conducted on 240 permanent maxillary incisors in four groups based on the type of tooth (central and lateral incisors) and degree of root development (complete or incomplete). Also 40 endodontically treated central and lateral incisors teeth in two groups were evaluated as negative controls. Pulp vitality was assessed by an expert clinician using pulse oximeter, cold test, and electric pulp test. Based on the true and false positive and negative responses, the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood, diagnostic accuracy, and diagnostic odds ratio were calculated. Results: The pulse oximeter showed diagnostic accuracy of 98.7% in the permanent central incisors with complete and incomplete roots and 100% in the permanent lateral incisors with complete and incomplete roots. The diagnostic accuracy of the electric pulp test was 76.2% and 92.5% in the incomplete and complete central incisors, respectively, and 76.2% and 83.7% in the incomplete and complete lateral incisors, respectively. The cold test had a diagnostic accuracy of 85% and 92.5% in the incomplete and complete central incisors, respectively, and 91.2% and 88.7% in the incomplete and complete lateral incisors, respectively. Conclusions: The findings of this study showed that pulse oximetry has a higher specificity and better accuracy than the cold test and the electric pulp test in assessing the pulp vitality in the diagnosis of vital teeth and should be introduced as a suitable method for this purpose and preferred to the cold and electric pulp tests for more evaluation to diagnose pulp vitality.

“…Radiographically, there was no periapical lesion or any adverse change with respect to 21. The patient did not respond to heat test and customised pulse-oximeter 16 gave a reading below 80, both suggestive of pulpal necrosis. Hence root canal treatment (RCT) followed by intra-coronal bleaching with 21 was planned.…”

In the era of minimum invasive dentistry and increased demand of esthetics, intra-coronal bleaching in an intact tooth is the most successful yet conservative method. Nonetheless oxidative materials such as hydrogen peroxide, carbamide peroxide, sodium perborate (monohydrate, trihydrate, tetrahydrate) used in combination or alone mixed with water for the same may create complications such as external root resorption. This case report illustrate the use of a bio-friendly material i.e. sodium perborate tetrahydrate with walking bleach technique.
