Endodontic Surgery Following Endodontic Treatment: a Case Report

The goal of endodontic treatment is to remove microorganisms from the root canal and ensure good sealing in order to establish favorable conditions for healing of the periapical lesion. A modern therapeutic approach is to use biomaterials for root canal filling, which, in most cases and regardless of the size of the periapical lesion, promote healing. However, the root canal exudate affects the treatment plan. Case report: A 29- year-old female patient comes to the Department of Dental Diseases, KBC Zagreb, referred by her doctor of dental medicine for the treatment of tooth 23. In her medical history, she states that the endodontic treatment was initiated six months ago and when the tooth is temporarily closed, the patient feels severe pain. A clinical examination revealed an open cavity. Radiologic examination indicated a relatively large radiolucent lesion with not-well-defined margins. Endodontic treatment was started and a cystic exudate was observed in the root canal during instrumentation. In consultation with the oral surgeon, the canal was instrumented, disinfected and obturated. Oral surgery was performed immediately after the endodontic procedure. During the surgical procedure an unusual round cyst-like formation was noticed around the apex of the tooth, which was removed and sent to PHD, that confirmed the formation was a radicular cyst. Conclusion: Every endodontic treatment is specific. Radiographically, the periapical leasion in this case is not presented as a well-defined radiopaque lesion, which is normally expected in cystic formations, but the root canal exudate was decisive for the therapy approach.
