Abstract:

Abstract：Objective To evaluate of clinical effects of apical resection and apical retention in the treatment of periapical disease. Methods Totally 38 maxillary and mandibular anterior teeth of 30 patients with periapical disease were chosen in Xiangyang Hospital of Chancheng District of Foshan City from January 2012 to June 2013. These patients were randomly divided into apical resection group and apical retention group（15 cases in each group）. The apical resection group underwent operation and the apical cut 2-3 mm，the apical retention group underwent operation but the apical retained. The patients were followed up for 3 and 6 months after operation，and through the examination of tooth mobility，fistula and measurement of alveolar bone density and bone height the analysis was made，and the clinical effects were compared between the two groups after operation. Results There was no statistical difference between the two groups in the tooth mobility and fistula which represented recurrence （P > 0.05），while there was statistical difference in alveolar bone density and bone height which representde bone index （P < 0.05）. Conclusion If the lesion can be totally removed，the periapical surgery of retaining apical has better clinical application value.
