[1] [2] It is designated by the International Organization for Standardization as standard ISO 3950 "Dentistry — Designation system for teeth and areas of the oral cavity". [ 3 ] The system is developed by the FDI World Dental Federation .
Comparison of alphanumeric notation, Palmer notation, ISO 3950 (FDI) notation, Universal Numbering System, and paleoanthropology notation. Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth.
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
The body cavity immediately behind the mouth opening, known as the oral cavity (or cavum oris in Latin), [2] is also the first part of the alimentary canal, which leads to the pharynx and the gullet. In tetrapod vertebrates , the mouth is bounded on the outside by the lips and cheeks — thus the oral cavity is also known as the buccal cavity ...
This common attachment makes the raphe a junction of the oral cavity, oropharynx, and nasopharynx. [3] The inferior alveolar nerve passes lateral to the raphe; the raphe is therefore a landmark for a nerve block of this nerve. [2] The general location of the raphe is indicated by the pterygomandibular fold. [3]
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by the hard palate.
The vertical dimension of the vowel diagram is known as vowel height, which includes high, central (mid), or low vowels. The horizontal dimension of the vowel diagram includes tongue advancement and identifies how far forward the tongue is located in the oral cavity during production.
3D medical illustration explaining the oral digestive system. The mouth is the first part of the upper gastrointestinal tract and is equipped with several structures that begin the first processes of digestion. [3] These include salivary glands, teeth and the tongue. The mouth consists of two regions; the vestibule and the oral cavity proper.
