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 ...
In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned tissues in their various states of health and disease.
For kids who are not enthusiastic about reading, it can be a massive challenge to get them to open a book for 10 minutes a day. The battle to get them to do it can be exhausting for everyone ...
This photo shows teeth #2-5 (Universal numbering system).Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay.This molar is both posterior, as well as distal, to the premolars in front of it.
Other variants include a bifid canal with a branch (~41%): [3] following the course of the main mandibular canal before re-joining it (forward or buccolingual type); terminating at the apex of a tooth, usually the molar teeth (dental type); opening as an accessory mental foramen. [4] A trifid mandibular canal variation has also been described ...
Edward Hartley Angle (June 1, 1855 – August 11, 1930) was an American dentist, widely regarded as "the father of American orthodontics". [1] He was trained as a dentist, but made orthodontics his speciality and dedicated his life to standardizing the teaching and practice of orthodontics.
The lesions are located on the mucosa, usually bilaterally in the central part of the anterior buccal mucosa and along the occlusal plane level (the level at which the upper and lower teeth meet).
