RESUMO

The evaluation of pulp vitality depends on diagnosis methods. The most widely used are thermal and electric stimulation. However, thermal and electric testing has limitations in providing accurate diagnosis. These tests are subjective and depend upon perceived response of the patient to a stimulus, as well as the interpretation of that response by the dentist. The limitations with present pulp testing methods are that they only indirectly monitor pulp vitality by measuring neural responses and not circulation. For traumatized teeth, the pulp can be affected in a variety of ways as a function of the severity of the injury therefore, that teeth may not respond to vitality test and establishing an accurate and expedient diagnosis is even more complicated. Pulse oximetry is a completely objective test, requiring no sub jective response from the patient and directly measures the blood oxygen levels. This present study purpose was to evaluate the efficiency of pulse oximetry for testing pulp vitality by establishing correlation parameters between blood oxygen levels from the patient’s index finger, positive control teeth and traumatized permanent teeth which do not respond positively to thermal test with refrigerant spray and do not show any other sign or symptom of mortification. The results showed that there was no statistical significance between blood oxygen levels from traumatized teeth at the three different measure times (initial, 30 and 60 days) and there was a correlation between blood oxygen levels from index finger and the traumatized teeth and control teeth and traumatized teeth.
