Article Abstract

Background: The superimposition in radiographic images makes it difficult to diagnose C-shaped canals using two-dimensional imaging techniques. A non-invasive technique called cone-beam computed tomography (CBCT) makes it easier to comprehend the C-shaped canal architecture along the root.

Aim: This study was undertaken to evaluate C-shaped canals in permanent second molars of mandible in a Saudi Arabian subpopulation using CBCT.

Methods: This research was a non-interventional, retrospective clinical trial. CBCT images of 452 mandibular second molars were selected from 300 patients. Every CBCT scan was interpreted by a certified oral radiologist to gather information regarding root canal anatomy, configuration, location, etc.

Results: The C-shaped canal was present in 51 (11.28%) of the 452 teeth. The C2 configuration was found to be the most common (28 teeth, 6.19%) followed by C3 (15 teeth, 3.31%), and C1 (7 teeth, 1.54%). Only one tooth (0.22%) had the C5 configuration, and none had the C4 configuration. The C-shaped canal was present in 35 (13.46%) of the 260 teeth from female patients and in 16 (8.33%) of the 192 teeth in male patients ( > 0.05).

Conclusion: The overall prevalence of C-shaped canals in mandibular second molars was 11.28% in Saudi population. This arrangement was more common in women than in men.

Root and canal morphology of mandibular second molars in a Chinese Kazakh population by cone-beam computed tomography.

BMC Oral Health

Department of Prosthodontics, School and Hospital of Stomatology, Liaoning Provincial Key Laboratory of Oral Diseases, China Medical University, Shenyang, 110002, China.

Objective: This study aimed to investigate variations in root and canal morphology of the mandibular second molars in a Chinese Kazakh population using cone-beam computed tomography (CBCT).

Methods: A total of 374 mandibular second molars from 236 patients were included in the retrospective study. The mandibular second molars were categorized based on the radiographic morphology of their external roots: non-fused roots (NFR), fused roots (FR), and single roots with a single canal (SS).

Introduction And Importance: Fusion of the maxillary second molar (MSMs) and the maxillary third molar is a rare dental anomaly, posing challenges in diagnosis and treatment due to complex root and canal anatomy, which can lead to caries, periodontal, and pulpal issues. While extraction is sometimes favored, root canal therapy (RCT) can preserve natural dentition and improve patient outcomes.

Case Presentation: A 40-year-old woman underwent a failed extraction of the left maxillary third molar and had chronic periapical inflammation in a fused maxillary second and third molar caused by severe caries.

Background/purpose: Inadequate understanding of tooth morphology can lead to missing root canals and procedural errors during root canal treatment. This study assessed the root and root canal morphology of maxillary first molars in a Japanese population, employing two classification systems and utilizing cone-beam computed tomography (CBCT).

Materials And Methods: The study included CBCT scans of 833 maxillary first molars from 642 Japanese individuals aged 16-80 years.
