Avaliação retrospectiva da condição pulpar após trauma dental

Abstract

The aim of this study was evaluate the pulp vitality in vivo status after trauma comparing dental sensitivity tests with pulp vitality test. We studied 71 traumatized teeth, 79 vital teeth in the side of a group of forty patients treated at Program of Assistance to patients with Trauma Dento-Alveolar - Outpatient Reference of School of Dentistry, Federal University of Uberlandia in the period between 2005 and 2010. The pulp vitality status of teeth after trauma was assessed by three sensitivity tests: electrical, thermal heat and cold and a pulp vitality test using a pulse oximetry. After statistical tests with Pearson's correlation was significant correlation between sensitivity tests, both in traumatized teeth checked as the vital teeth in the side. There was no significant correlation between pulp sensitivity test and pulp vitality test. However, the oximeter alone showed a high percentage of diagnosis of pulp vitality.The results demonstrated that pulse oximetry was the test that was more efficient in assessing the pulp vitality status of teeth after trauma.
