ABSTRACT
In this report, attempts have been made to present as an interesting case report overfilling of the root canal, which is one of the most important errors caused by a dentist. The iodoform paste that was applied as a result of canal treatment, which was performed on the left mandibular second premolar, did not only overfill the apical lesion of that tooth but also extended as far as the apical region of the left mandibular second molar. In the periapical and panoramic radiographs, it is seen that the overfilled canal filling material extended as far as the angulus region of the mandible. It is also observed that the canalis mandibularis was not affected by this process and that the overfilled canal paste extended through the trabeculae of the mandibular bone. The fact that the paste disappeared after a short period of time supports the view that the canal filling material was the iodoform paste, which was resorbed.
