Software-supported periodontal diagnostics with 3D CBCT compared with conventional 2D panoramic imaging and clinical diagnostics: a prospective study.

Aim: The objective of the present study was the software-supported evaluation of the measurement accuracy between CBCT and panoramic radiographs in the assessment of the periodontal bone level in patients with periodontitis, and the comparison of this with clinical periodontal parameters.

Materials And Methods: Twenty patients with severe periodontitis (stage III to IV) were evaluated clinically and radiographically (panoramic radiographs and CBCT). Diagnostic interpretation comprised three blinded investigators with different levels of experience.

Case report: endodontic and surgical treatment of an upper central incisor with external root resorption and radicular cyst following a traumatic tooth avulsion.

In the age group between 6 and 12 years, trauma to the upper incisors happens frequently. In the case of avulsion, a replantation is the state-of-the-art treatment; however, it may lead to several complications, particularly if suitable posttraumatic management is not carried out. External cervical resorptions as well as apical granuloma and cysts due to microbial contamination of the root canal are common complications.
