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 ...
Dental composite based approaches to tooth surface loss allow for easy adjustment or removal if required. One study published in the British Dental Journal, 2011 found that patient satisfaction was high when composite restorations were used in the Dahl approach and that the median survival time was between 4.75 and 5.8 years.

Occlusion, in a dental context, means simply the contact between teeth.More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.
It is estimated that nearly 30% of the general population present with malocclusions that are in great need of orthodontic treatment. [1] However, the term dentofacial deformity describes an array of dental and maxillo-mandibular abnormalities, often presenting with a malocclusion, which is not amenable to orthodontic treatment alone and definitive treatment needs surgical alignment of upper ...
The term dentistry comes from dentist, which comes from French dentiste, which comes from the French and Latin words for tooth. [6] The term for the associated scientific study of teeth is odontology (from Ancient Greek: ὀδούς, romanized: odoús, lit. 'tooth') – the study of the structure, development, and abnormalities of the teeth.
The condyle can only be in the same place as it was the last time it was positioned by the dentist if it is consistently moved to the most superior and anterior position within the fossa. It is a physiologic position that is used for reproducibility. The Temporomandibular Joint is not restricted to Centric Relation in function.
The dental dam is prepared by punching one or more holes in the dental dam sheet to enable isolation of the appropriate number of teeth required for the dental procedure. The dental dam is then applied to the tooth, anchored into place using a metal or flexible plastic clamp (chosen according to the tooth and area it will be applied to).
A number of different 'margins' are involved in dentistry. The edge of tooth structure that is prepared to meet the edge of a prosthetic crown is called a margin, as is the aforementioned edge of the crown; an example of this usage would be "a poorly fitting crown might exhibit marginal leakage."
