Résumé
<p><b>OBJECTIVE</b>To investigate the pulp prognosis and influence factors of dentin-fractured teeth.</p><p><b>METHODS</b>Case records of dentin-fractured teeth treated with indirect pulp capping and with more than 2 years follow-up were collected. The data related to trauma information and pulp prognosis were recorded and the influence factors were analyzed by Logistic regression.</p><p><b>RESULTS</b>This study consisted of 205 cases with 242 dentin-fractured teeth. Among 242 teeth, pulp necrosis occurred in 78 teeth(32.2%) and pulp calcification occurred in 3 teeth(1.2%). The success rate of indirect pulp-capping on dentin-fractured teeth was 67.8%. During observation period, 141 out of 177 young permanent teeth completed root development. The extent of fracture close to pulp was an indicator for pulp prognosis (P=0.001).</p><p><b>CONCLUSION</b>The prognosis of indirect pulp-capping on dentin-fractured permanent teeth is good. The extent of fracture close to pulp should be considered to evaluate the prognosis of the pulp.</p>
