Radiology
We performed a CB-CT (CB-CT; KaVo 3D eXam ConeBeam XG; KaVo Dental GmbH, Biberach / Riss, Germany) after initial orthopantomography OPG (Orthophos XG, Sirona Dental Systems, Bensheim, Germany). As a result, we detected sclerotic apical changes by CB-CT (CB-CT; KaVo 3D eXam ConeBeam XG; KaVo Dental GmbH, Biberach / Riss, Germany) associated with all teeth in Hounsfield and categorized these according to Jamdade & John, (2013) [6].
We compared osteodensitometric results (CB-CT -O) to each other ​​and assigned them according to the clinical-radiological categories of maturation of periapical dysplasias [7-9]. We performed radionuclide (BS) two hrs after an i.v. Injection of technetium-99m methylene diphosphonate (99Tcm MDP; 520.0 MBq after 2h; Pixel Size 2.1, SL 1880; SP 4.2mm/sec) in anteroposterior and lateral projections [6,10] and diagnosed , via bone scintigraphy [BS] and CB-CT to exclude aggressive bone lesions [6]. We verified both findings and correlated these with dental nerves and bone specimens [10] (Fig. 1).
The patient provided informed consent for investigation with a technetium bone scan.
