title: The effect of pulp obliteration on pulpal vitality of orthodontically intruded traumatized teeth.
abstract: Limited information exists on the impact of pulp obliteration on pulpal vitality of orthodontically treated traumatized teeth. Pulpal condition was examined in 269 traumatized maxillary incisors after orthodontic intrusion (OT group) and in 193 traumatized maxillary incisors without subsequent orthodontic treatment (C group). According to the degree of initial pulp obliteration, the teeth were divided into three categories: teeth without, teeth with partial, and teeth with total pulp obliteration. Teeth in the OT group revealed a significantly higher rate of pulp necrosis than teeth in the C group (p < 0.001). In addition, teeth in the OT group with total pulp obliteration showed a significantly higher rate of pulp necrosis than teeth without (p < 0.001) or only partial pulp obliteration (p = 0.025). The results indicate that traumatized teeth with total pulp obliteration have a higher susceptibility to pulpal complications during orthodontic intrusion than traumatized teeth without or only partial pulp obliteration.
