Elimination of root canal filling material from the root and the bone
We present a case of a 43 years old male with mandibular central incisors trauma which dates back to 1985, i.e. 34 years before the current study. At that time the patient is 9 years old and the teeth are with incomplete root development. An endodontic treatment of 31 and 41 is conducted, and followed by phisioterapy. The patient has no complaints, and the first radiographic investigation is made 12 years later, in 1997. Radiograph reveals teeth with non-exact endodontic treatment – canals are over-filled and short-filled in the same time. Overextension of filling material into the surrounding bone tissues with a resorption around it on 3-4 mm apically to 31 is confirmed. Voids are present in the root filling and between root filling and root canal walls. There is a loss of the alveolar bone between 31 and 41.
An endodontic revision with apical surgery is recommended, but no treatment is executed. We observe a complete absorption of over-filled canal filling material from the bone for a period of 25 years. At the 34 year we see only a slight lightening at the place of the overfilled material and an almost complete lack of canal filling of 31.
34 years after the treatment, the patient has not received any treatment and has never had any complaints. The teeth are still restored with the temporary obturation from 1985. Over time, root canal filling is eliminated not only from the bone, but from the root canals.
