Abstract
Objective To explore the effects and related influential factors of replantation after complete dislocation of anterior teeth/tooth on mixed dentition patients experiencing tooth transitions. Methods Analysis of 48 patients with 58 traumatic anterior teeth were made based on treatments recieved and clinical observations.After the reimplantation for the traumatic anterior teeth, patients returned for dental pulp test and periodontal examination. 2 weeks later, apexification was performed after the dental pulp test had indicated a negative result.Six months to 3 years after apexification, permanent canal filling treatment was made once the apical had been fully formed. Results three years after the replantation,5 teeth exist vitality with a dental pulp survival rate of 8.62%; X-ray examination indicates that out of the 53 teeth have had apexification and canal filling treatment:25 teeth's tooth roots have periodontal ligament fully recovered (bined together or have been healed),30 teeth's teeth root have fully recovered iodontal ligaments and partial recover of the bone structures.3 of the teeth have indicated different degree of internal and external absorption of tooth root.but nooe came off. Conclusion Early diagnosis, reasonably treatment.and dental pulp vascular regeneration are the key to success of tooth reimplantation. Apexification is important since it enhances tooth rooth development thus rebuilt the tooth rooth and allows for the cementum deposit at the root apex, closing the apical cloure which is essential for treating traumatic anterior teeth when patients are under tooth transition period.In addition,tooth root canal operation can prevent or reduce traumatic teeth's tooth root absorption.关键词
