• To evaluate the effect of closing root apex of permanent teeth with mineral trioxide aggregate to form barricade in root tip under the dental operating microscope. 63 teeth treated in our department with open root apex and periapical periodontitis were selected, MTA was used to rigorously close the root apex under microscope, and thermoplastic gutta pertscha was used to fill dental root after formation of barricade in the root tip. All patients revisited regularly for clinical examinations after treatment. Among the 63 treated teeth, only one tooth (23) was insufficiently filled because of the long dental root and unclear field of vision under microscope, the remaining 62 teeth were filled adequately. The postoperative dental film showed 43 teeth were properly filled while 17 had a little over-filling. The patients were rechecked after three months, and the results showed that 2 patients underwent retro-filling because of fistula, 2 patients were lost during follow-up period, and the remaining patients reache
