The bisecting angle technique is an older method for periapical radiography. It can be a useful alternative technique when the ideal receptor placement using the paralleling technique cannot be achieved, for reasons such as anatomical obstacles e.g. tori, shallow palate, shallow floor of mouth, or narrow arch width.
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 ...
His 1904 paralleling and bisecting angle techniques would not become popular until the work of Dr. Gordon Fitzgerald of the University of California in the late 1940s. [11] [12] The practice of using radiographs began a new era in dentistry, as dentists could finally see evidence of past dental treatments. [10]
Among his contributions to dentistry are the rules of isometry that allow for the bisecting angle to accurately reproduce dimensions in x-radiology, and extraoral anæsthetising techniques. During the WW2 in 1941 Cieszyński with a number of other Polish university professors was summarily executed by the invading German forces in Lviv during ...
ConeBeam computerized tomography image of a post-operative orthognathic surgery. Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, or even more common DentoMaxilloFacial Radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

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 ...
Periradicular surgery should be very considered where previous endodontic treatment has failed, and possible re-root treatment is the preferred option. [4] If re-root treatment is not possible, will not correct the problem or patient factors prevent it, periradicular surgery is indicated.
