CLINICAL STUDY ON THE INTUBATION TO PERIAPICAL LESIOON

The author has experienced 8 cases of periapical lesion which were very closed to adjacent root tip. To avoid damage on neighboring nerve and blood supply polyvinyl tube was inserted through buccal window leaving a little pathological changes in involved area. The results are as follows: 1. The purpose to maintain adjacent tooth vitality was achieved by means of intubation in the lesion. 2. Swelling and pain after operation was rather lesser than routine apical surgery, because of drainage. 3. The total treatment period seems longer than that of routine apical amputation.
