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.
