Resumo
This study microscopically analyzed the pulp of 20 human permanent traumatized
teeth with intact crowns and clinical diagnosis of pulp necrosis, and evaluated this diagnosis
concerning histopatologic findings. The removed pulp specimens were stained with hematoxylin
and eosin, for evaluation of possible morphological alterations, and Brown e Brenn method, to verify
microorganisms. General subjective analysis and statistical analyses (diagnostic analysis) revealed
that 3 teeth (15%) did not present pulp tissue, being characterized as complete autolysis; analysis of
pulp samples was performed on the other 17 (85%) cases, among which 3 (15%) exhibited partial
necrosis without possibility of repair and 14 (70%) presented complete necrosis; in 12 (65%) out
of 17 pulps the presence of microorganisms could be conformed by Brown and Brenn method and
none of the clinical criteria employed for the diagnosis of pulp necrosis in traumatized teeth was
pathognomonic. The present results allowed the following conclusions: concerning the microscopic
findings, 100% of traumatized teeth presented pulp necrosis and 65% of them with microorganisms;
the pulp vitality tests to heat, cold and vertical percussion test were the most reliable to diagnose
pulp necrosis in traumatized teeth.
