Prevalence of Middle Mesial Canals and Isthmi in the Mesial Root of Mandibular Molars: An In Vivo Cone-beam Computed Tomographic Study.

Introduction: Many studies have investigated the morphology of the mandibular molar, but the prevalence of the middle mesial (MM) canal in the mesial root of the mandibular molar is still the subject of controversy. In addition, in previous literature, a true MM canal has not been clearly distinguished from an isthmus between the mesiobuccal and mesiolingual canals. Therefore, the objectives of this study were 2-fold: METHODS: Ninety limited field of view cone-beam computed tomographic scans were observed.

Incidental Findings on Cone Beam Computed Tomography Studies outside of the Maxillofacial Skeleton.

Objective. To define the presence and prevalence of incidental findings in and around the base of skull from large field-of-view CBCT of the maxillofacial region and to determine their clinical importance. Methods.

Radiographic manifestations of Mönckeberg arteriosclerosis in the head and neck region.

Mönckeberg sclerosis is a disease of unknown etiology, characterized by dystrophic calcification within the arterial tunica media of the lower extremities leading to reduced arterial compliance. Medial calcinosis does not obstruct the lumina of the arteries, and therefore does not lead to symptoms or signs of limb or organ ischemia. Mönckeberg sclerosis most commonly occurs in aged and diabetic individuals and in patients on dialysis.

Arrested Pneumatization of the Sphenoid Sinus on Large Field-of-View Cone Beam Computed Tomography Studies.

Arrested pneumatization of the sphenoid sinus is a normal anatomical variant. The aim of this report is to define cone beam computed tomography (CBCT) characteristics of arrested pneumatization of sphenoid sinus in an effort to help differentiate it from invasive or lytic skull base lesions. Two cases are presented with incidental findings.

Incidental findings of skull-base abnormalities in cone-beam computed tomography scans with consultation by maxillofacial radiologists.

Introduction: Cone-beam computed tomography (CBCT) gives orthodontists and other dental clinicians 3-dimensional information for planning treatment in the craniofacial region. Often overlooked are incidental findings outside the treatment region of interest.

Methods: Two patients with incidental findings of skull-base abnormalities are presented.

Skeletal and soft-tissue incidental findings on cone-beam computed tomography images.

Cone-beam computed tomography provides orthodontists with 3-dimensional images of the craniofacial region and valuable information for diagnosis and treatment planning of craniofacial or dental anomalies. However, a narrow focus on the skeletal and dental contributions to malocclusion can cause failure to identify skeletal or soft-tissue pathologies of the craniofacial structures unrelated to the orthodontic concerns. Two cases are presented that demonstrate skeletal and soft-tissue anomalies identified as incidental findings on cone-beam computed tomography scans of asymptomatic orthodontics patients.

Cone beam computed tomography imaging in the evaluation of the temporomandibular joint.

A radiological examination is an essential part of the diagnosis and management of temporomandibular joint disease. Accurate evaluation of the TMJ has been difficult due to the superimposition of other structure in convention radio graphs. Cone beam computed tomography provides precise imaging of TMJ anatomy without superimposition and distortion.
