Early diagnosis of pulp condition in cases of teeth with trauma is very important not only to preserve the vitality of the pulp but also to prevent both early and late traumatic complications. We investigated 120 frontal teeth with traumas. The teeth were tested on 1-st day, 15-th day, 30-th day, 3-rd month, 6-th month by pulse oximetry (PO) and electric pulp test (EPT). The results we received from pulse oximetry show that the saturation levels immediately after the trauma are very high, reaching 90%. Over the time, there has been a tendency for reduction of saturation, reaching a level of 82% by the 6th month, which is within the limit of the norm. The differences between the obtained saturation levels are statistically significant up to the 30th day of the trauma (p <0.05). The EPT results showed that the highest values were immediately after the trauma - 53 μA. The average values obtained for all periods up to and including 3-rd month are higher than the established norms. They differ statistically between each other and from the values, measured at 6-th month, which are average 8 μA. Comparing the circulatory response and the innervation of the traumatized teeth, we could conclude that the blood circulation recovers more quickly within one month, whereas the nerve conduction is restored until the 6-th month. Thus, the implementation of pulse oximetry in dentistry is of great benefit for the total pulp diagnosis – not only of the nerve, but also of the blood circulation.

Pulse oximetry as a diagnostic tool in dental medicine

D. Kosturkov, Ts. Uzunov, P. Uzunova

Proceedings Volume 10226, 102261C (2017) https://doi.org/10.1117/12.2262267

One of the most widespread optical methods used in biophotonics is the pulse oximetry, which is based on the measurement of light-modulated pulse wave of blood. This is a non-invasive, objective method for evaluation of the blood supply. Recently it has become very popular in dental medicine for the measurement of the condition of pulp microcirculation. The aim of our research is to evaluate the possibilities of pulse oximetry for estimation the pulp microcirculation in intact teeth among young patients. Results obtained clearly show that this method can be applied to assess the pulp condition and could be used in clinical practice in combination with other diagnostic methods.
