[Apex and periapical periodontium of teeth with endodontic-endosseal pin fixation]

Teeth with endodontic-endosteal pin fixation were observed for several years and radiolucencies that could be interpreted as chronic inflammation, were found in the periapical region of these teeth. The cause is sought in the iatrogenic noxa of the originally applied method. It is recommended to expose the apex of teeth to be provided with endodontic-endosteal pin fixation and to shorten the apex by grinding off 2-3 mm.
