Oxímetro de pulso como recurso auxiliar no diagnóstico endodôntico.

Abstract

In Dentistry, specifically on Endodontics field, the use of dental auxiliary tests to determine the pulp condition are extremely important to develop a safely diagnostic. Several methods are presented, such as sensitivity test and vitality tests. In the vitality tests are included the Pulse Oximetry, which is an atraumatic technique that measures the oxygen saturation inside of the dental pulp. The literature neatly has shown the mechanisms of its function, limitations and variations of the technique. The aim of this work was to study the oximeter technique, also make a brief comparison with sensitivity tests, and to evaluate its reliability over different clinical stages of the dental pulp. The results of this study have demonstrated that Oximetry has more concrete standards for evaluation of dental pulp than thermal and electrical tests. Thus, it has presenting constant rates and it has not reported false positives as the others techniques. Furthermore, the pulse oximeter has shown its ability to safely diagnose cases of traumatic teeth, necrotic and vitality pulp. However, there are no bibliographic agreement and relevance about the pulse Oximetry efficacy in front of different pulpal inflammatory stages.
