Pulse Oximetry as a Diagnostic Tool to Determine Pulp Vitality: A Systematic Review

Pulse oximetry (PO) can be used as a technique to assess vascularization. Although it is commonly in the field of medicine, still has limited use dentistry. The aim this study evaluate, by means systematic review, if pulse viable and effective system determine pulp vitality clinical criteria for its use. A literature search was performed Medline, Scopus, Embase, Web Science databases. Clinical studies using tool permanent teeth were eligible. Quality assessment included following Assessment Diagnostic Accuracy Studies (QUADAS-2) guidelines. total 24 articles review. subjective test most compared PO cold test. shown good sensibility specificity, been different situations. high potential diagnosis vitality. However, absence specific oximeter dental practice, among other limitations, added lack evidence on how systemic oral pathologies may affect pulp’s oxygen saturation levels, which hinders
