Abstract Synopsis


Prof. Dr. Paula Perlea, Assist. Prof. Dr. Cristina Coralia Nistor


Besides the preoperative periapical radiography, CBCT is a complementary imaging
examination for endodontic treatment. Both are highlighting the morphology of the
endodontic system, the pathological and iatrogenic aspects necessary for the clinician, as well
as the healing of the periapical lesions. However a part of the imagistic information remains
unrevealed by using the conventional radiograph. CBCT is in certain situations mandatory
for endodontic purposes. Sometimes even this accurate imagistic exam fails to always detect
the clinical reality, the resolution of the device having a major role and being correlated with
the size of the anatomical details so that they can be visualized. Also, the presence of the
artefacts due to radiopaque obturation or restoration materials, interferes with the accuracy of
the image. CBCT should therefore be correlated with clinical examination using the dental
operative microscope (DOM), which by magnification and coaxial illumination can highlight
many endodontic aspects (extra channels, bifurcated channels, cracks, fractures). The
presentation shows the indications and limits of CBCT in endodontic treatment, exemplified
with original clinical cases, documented by X-rays, CBCT and DOM, which reveals a series
of special endodontic situations when correct interpretation of radiological images and CBCT
scans are of tremendous importance for the success of the endodontic treatment.
