简要总结
The participants were divided into two groups : group one ( Trunatomy file group)(n=10) was mechanically prepared the canals by Trunatomy file and group two ( Edgeendo x7 file group) ( n=10) was prepared the canals by Edgeendo x7 file, the participants were assessed pain preoperatively and postoperatively by Visual Analog Scale(VAS)
详细描述
Patients : 20 patients with symptomatic apical periodontitis related to mandibular premolars were selected.after proper anathesia, Access cavity was ppreformed.The working length measured using apex locator.chemomechanical preparation was done .for trunatomy file group ,using file sequence according to manufacture's instructions until medium one .for edgeendo group ,using file sequence also according to manufacture's instructions until file size 35 taper4.Apical fluid samples was collected by paper point from the both preoperatively and before obturation and also pain was assessed pre and post opertively.finally,the root canal were filled by gutta-percha and resin based sealer.the access cavity was restored by glass ionomer restoration.
