Devitalization or only denervation of teeth after jaw fractures

There were 72 fractures in 50 patients. Three years after the injury, 7.6% (17/222) of teeth remain denervated. The most denervated teeth are molars while the least denervated are incisors. During the second and the third year following injury 3 teeth were devitalized which is 1.35% of the initially "avital" teeth or 17.6% of those denervated after one year. Good reposition is no guaranty for reinnervation. Denervation may occur even without dislocation. The dental pulp is vitally stable one year after the mandibular fracture. Denervated tooth is not devitalized and should not be treated if neither clinical nor radiologic signs of devitalization are present.
