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 film or sensor.
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 ...
Lateral cephalometric radiograph is a radiograph of the head taken with the x-ray beam perpendicular to the patient's sagittal plane. Natural head position is a standardized orientation of the head that is reproducible for each individual and is used as a means of standardization during analysis of dentofacial morphology both for photos and ...
This x-ray was taken for an unrelated assessment of wisdom teeth, and the Stafne defect was a chance finding. Axial computed tomograph of the same person. The Stafne defect appears as a well corticated 1 cm round defect in the medial cortex of the mandible in the right angle of the jaw (arrowed).
Oral and maxillofacial pathology refers to the diseases of the mouth ("oral cavity" or "stoma"), jaws ("maxillae" or "gnath") and related structures such as salivary glands, temporomandibular joints, facial muscles and perioral skin (the skin around the mouth). [1] [2] The mouth is an important organ with many different functions. It is also ...
Three-dimensional analysis of the clinical photos, X-rays and 3D CT scans from the front, lateral, oblique, basal and overhead views are required for a detailed evaluation. [3] The level of protrusion of the mandible angle, the size of the masseter muscle and the overall structure of the jaw are evaluated.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
The mandible in particular has the most differential typical growth anomalies than any other bone in the human skeleton. This is due to variants in the complex symmetrical growth pattern which formulates the mandible. [1] The mandible in particular plays a significant role in appearance as it is the only moving part of the facial skeleton.
