Pulse oximetry is a technique used to measure the levels of blood oxygen saturation. Because this technique is regarded as non-invasive, easy to apply, and accurate technology, the number of possible applications in general dentistry practice has been gradually increasing. The aim of the present study was to summarise the contemporary research literature concerning the use of pulse oximetry in paediatric dentistry. We made a critical evaluation of the clinical applications of pulse oximetry and the advantages and disadvantages of this technique. Knowledge of innovative methods and techniques for treatment and diagnostics by paediatric dentists is a valuable advantage in dealing with the functional problems in attending dental patients. The expository analysis allows reviewing the succession of this diagnostic approach.
