[Prospective comparative randomized study of tooth apex resection and orthograde root filling with Guttapercha and titanium pins].
The prospective randomised study on the root apex resections with orthograde root filling comparing Guttapercha with Titan pins encompasses 500 patients with 633 operations on all front teeth and premolars. The patients were divided into three preoperative stages so that for this broadly defined diagnoses comparable collectives could be built. After an average postoperative interval of 21 months, 258 patients with 298 resected teeth could be evaluated. From these, 188 root apex resections had been treated with Guttapercha and 110 with Titan pins. 73.5% of the root apex resections were successful, whereby the group treated with Guttapercha was more successful by 7%. The comparatively high failure rate of 26.5% is attributable to the broadly defined diagnosis and the long follow-up period.
