Endodontic management of a maxillary first molar with two palatal roots and a single fused buccal root diagnosed with spiral computed tomography - a case report

Two Canals in Maxillary First Molar: A Rare Dental Entity

“…6 After confirmation of this unusual morphology by spiral computerized tomography, incidentally they mentioned that the other maxillary first molar in their reported patient had also a similar morphology, but it had only one buccal canal in its single buccal root. 6,7 Radiographs produce only a 2-dimensional image, resulting in superimposition and distortion. Since it cannot be useful in cases with complex root canal anatomy, it is crucial to use all of the armamentaria to diagnose and treat the entire root canal system.…”

“…5 Gopikrishna et al (2008) presented the endodontic management of a maxillary first molar with a single-fused buccal root with two canals and 2 palatal roots. 6 After confirmation of this unusual morphology by spiral computerized tomography, incidentally they mentioned that the other maxillary first molar in their reported patient had also a similar morphology, but it had only one buccal canal in its single buccal root. 6,7 Radiographs produce only a 2-dimensional image, resulting in superimposition and distortion.…”

Endodontic Management of a Tooth with Radix Entomolaris and Five Root Canals

“…Therefore, these radiographs are of limited value in cases with complex root canal anatomy (23). Interpretation and appraisal based on a 2D radiograph may alert the clinician to the presence of aberrant anatomy but would not be able to present the variable morphological structure of root canals and their interrelations (24). Hence, it is mandatory to use all the available diagnostic aids to locate and treat the entire root canal system (25).…”

“…Nance et al (26) showed that tuned aperture, computerized tomography imaging enabled a significant increase in canal detection as compared to conventional radiography. Gopikrishna et al (24) used spiral computerized tomography for the confirmatory diagnosis of a morphological aberration in the maxillary first molar.…”

Maxillary second molar with five root canals: a case report

“…Dodatne informacije o anatomiji korijenskih kanala mogu se dobiti pažljivim posmatranjem pozicije endodontskih instrumenata u korijenskom kanalu kao i deformacijom instrumenata od nerđajućeg čelika prilikom plasiranja u kanal. Novija istraživanja ukazuju na prednosti primjene konusne ili spiralne kompjuterizovane tomografije za identifikaciju spoljašnje i unutrašnje morfologije [4,5,16].…”
