Buccal Object Rule
The buccal object/SLOB rule is a method used to determine the relative position of two objects in the oral cavity using projectional dental radiography. Clark's Rule In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. 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 impossible to know which one is in front of the other. To determine which is in front and which is behind, Clark proposed his 'SLOB rule'', as a complicated set of three radiographs, but which can be simplified as follows using just two: :Expose another film while angle of the x-ray beam has been changed. If an object moves in the ''same'' direction as the source of the x-ray beam, it is ''Commonly used terms of relationship and compari ...

Oral Cavity
In animal anatomy, the mouth, also known as the oral cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alimentary canal, bounded on the outside by the lips and inside by the pharynx. In tetrapods, it contains the tongue and, except for some like birds, teeth. This cavity is also known as the buccal cavity, from the Latin ''bucca'' ("cheek"). Some animal phyla, including arthropods, molluscs and chordates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify bilaterian animals into protostomes and deuterostomes. Development In the first multicellular animals, there was probably no mouth or gut and food particles were engulfed by the cells on the exterior surface by a process known as endocytosis. The particles became enclosed in vacuoles into which enzymes were secre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonly Used Terms Of Relationship And Comparison In Dentistry
This is a list of definitions of commonly used terms of location and direction in dentistry. This set of terms provides orientation within the oral cavity, much as anatomical terms of location provide orientation throughout the body. Terms Combining of terms Most of the principal terms can be combined using their corresponding combining forms (such as ''mesio-'' for ''mesial'' and ''disto-'' for ''distal''). They provide names for directions (vectors) and axes; for example, the coronoapical axis is the long axis of a tooth. Such combining yields terms such as those in the following list. The abbreviations should be used only in restricted contexts, where they are explicitly defined and help avoid extensive repetition (for example, a journal article that uses the term "mesiodistal" dozens of times might use the abbreviation "MD"). The abbreviations are ambiguous: (1) they are not spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Alabama School Of Dentistry
The University of Alabama School of Dentistry is the public dental school located at the University of Alabama in Birmingham, Alabama, United States. The dental school was founded in 1948 and is the only dental school in Alabama. History The UAB School of Dentistry, a unit of the Medical Center of the University of Alabama at Birmingham, was created by an act of the state legislature in 1945, the same year that the School of Medicine moved to Birmingham from the university campus in Tuscaloosa and became a four-year school. The School of Dentistry admitted its first class of students in October 1948. In addition to its first professional degree ( D.M.D.) program, the school offers accredited postdoctoral programs in twelve areas of study. The development of "four-handed dentistry" and the expanded utilization of trained auxiliary personnel were pioneered at this institution. From 2012 through 2015 the School was ranked first in research funding from the National Institute of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
