Morphological Characteristics and Classification of Mandibular First Molars Having 2 Distal Roots or Canals: 3-Dimensional Biometric Analysis Using Cone-beam Computed Tomography in a Korean Population.

Introduction: The aim of this study was to determine the morphologic characteristics of mandibular first molars having 2 canals in distal roots. Interorifice distance, buccal bone thickness, and root curvature were evaluated using cone-beam computed tomography images in a Korean population.

Methods: In total, 1958 mandibular first molars were evaluated in axial, coronal, sagittal, and paraxial planes.

Background Intestinal 18F-FDG Uptake Is Related to Serum Lipid Profile and Obesity in Breast Cancer Patients.

Background: This study investigated the relationships between background intestinal uptake on 18F-FDG PET and cardio-metabolic risk (CMR) factors.

Methods: A total of 326 female patients that underwent 18F-FDG PET to determine the initial stage of breast cancer were enrolled. None of the patients had history of diabetes or hypertension.
