Popis: Svrha: Željelo se predstaviti netipičan slučaj C-oblika kanala u vestibularnom korijenu trajnoga maksilarnog kutnjaka, a pritom su korišteni kompjutorizirana 3D tomografija koničnom zrakom (CBCT) i dijagnostički uređaj PreXion. Materijali i metode: Nakon rutinskoga pregleda 50-godišnja pacijentica upućena je u privatnu dijagnostičko-radiološku kliniku u Recife-Pernambucu u Brazilu. Tijekom pregleda uočena je neuobičajena anatomija vestibularnog kanala u obliku velikoga slova C s meziodistalnom anastomozom koja se protezala od apikalne do cervikalne trećine, a otkrivena je aksijalnim rezovima na uređaju PreXion 3D. Rezultati: Premda se C-oblici korijenskih kanala najčešće nalaze u drugim mandibularnim kutnjacima, u ovom radu opisana je rijetka pojava u drugom maksilarnom trajnom molaru. Zaključak: PreXion 3-D CBCT najnoviji je uređaj visoke rezolucije koji pomaže pri postavljanju dijagnoza anatomskih varijacija poput C-oblika korijenskih kanala. Ipak, uporaba takvih sustava prikazivanja ne preporučuje se u rutinskoj uporabi.
Objective: The aim of this study was to present an atypical case of a C-shaped root canal that was present in the vestibular root of a permanent maxillary second molar using PreXion 3-D cone-beam computed tomography (CBCT) as a diagnostic device. Materials and Methods: A 50-year-old female patient was referred for routine examination to a private diagnostic imaging clinic in Recife-Pernambuco. During the physical examination, the presence of an unusual C-shaped anatomy in the vestibular canal with a mesiodistal interconnection that extended from the apical to the cervical third was detected in axial slices acquired with a PreXion 3-D scanner. Results: Although C-shaped root canals are most frequently observed in the mandibular second molar, this case presented a rare finding in the permanent maxillary second molar. Conclusions: PreXion 3-D CBCT has emerged as a new highresolution imaging test technology, thus assisting with the diagnosis of anatomical variations such as C-shaped root canals. However, such imaging technology is not recommended for routine use.
