Dentigerous cysts may also involve odontomas, which by their nature also have tooth crowns. The radiolucency is generally well defined and well corticated. The radiolucency often have a sclerotic border indicating bony reaction, but a secondarily infected cyst may display ill-defined borders.
Lateral periodontal cysts radiographically present as a rounded, teardrop shape that are usually less than 10mm in size, presenting with a uni-cystic well-delineated radiolucency. Lesions are situated usually between the tooth lateral surface between the root apex and alveolar crest. [10] A prominent cortical boundary [11] is also usually observed.
The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots. The resulting pulpal necrosis causes proliferation of epithelial rests of Malassez which release toxins at the apex of the tooth. The body's inflammatory response will attack the source of the toxins, leading to ...
Periapical radiograph showing peri-radicular radiolucency and bone loss caused by an odontogenic infection under the roots of two anterior teeth in a 30-year-old patient. An odontogenic infection is an infection that originates within a tooth or in the closely surrounding tissues. [1]
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...
Vessels and nerves: :25. dental :26. periodontal :27. alveolar through channel In dental anatomy, the apical foramen , literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's ...
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the ...
The diagnosis of pulp necrosis can be based on the following observations: negative vitality, a periapical radiolucency, a grey tooth discoloration and even peri-apical lesions. [17] This altered translucency in the tooth is due to disruption and cutting off of the apical neurovascular blood supply.
