Teaser

Odontogenic infections represent a common clinical problem in patients of all ages. The presence of teeth enables the direct spread of inflammatory products from dental caries, trauma, and/or periodontal disease into the maxilla and mandible. The radiographic changes seen depend on the type and duration of the inflammatory process and host body response. Imaging plays a central role in identifying the source of infection and the extent of the disease spread and in detecting any complications. Many different imaging modalities can be used. The radiographic features associated with acute and chronic inflammatory processes are discussed.

Teaser

Malignancies in the maxillofacial region are rare but comprise a broad spectrum of lesions. Given the potential for malignancies to mimic dental/sinus/temporomandibular joint pathology or remain asymptomatic, the judicious radiologist will be familiar with the initial and unique malignant changes affecting the dentition, periodontium, and supporting osseous structures on conventional film, dental, and sinus imaging. This article is meant to serve as a complement to the many excellent texts dedicated to advanced imaging techniques for the staging of known malignancies. The lesions discussed are a representative sample of malignancies involving hard tissues of the maxillofacial complex but are far from complete.

Fibroosseous and Other Lesions of Bone in the Jaws

Teaser

Fibroosseous lesions in the jaws have similar histologic and radiographic features. Despite their similarity, management varies significantly. In this article, common fibroosseous lesions and key radiographic features are described. Many of the fibroosseous lesions are diagnosed radiographically, without performing histologic examinations. For some of the fibroosseous lesions, for example, periapical osseous dysplasia, histologic examination is contraindicated. Cherubism and fibrous dysplasia have specific radiographic findings; these conditions can be diagnosed radiographically. Accurate diagnosis conditions is essential; some conditions do not require any intervention, while others require surgical resection. Patient demographics, for example, age, gender, and race, play important roles in diagnosis.

Radiology of Implant Dentistry

Author(s): Asma'a Abdurrahman Al-Ekrish

Teaser

The article presents an overview of the goal of imaging at each stage of implant therapy and the usefulness and limitations of multidetector computed tomography (MDCT) in achieving those goals. Various MDCT protocols of use in implant imaging also are presented, with an emphasis on dose reduction and the use of iterative reconstruction techniques. Also discussed are options for viewing and analysis of CT images, issues related to appropriate image reformatting and interpretation, interactive treatment planning, and transfer of information from the images to the surgical field during implant surgery using surgical guides and CT-guided navigation systems.
