Lingual surfaces can also be described as palatal when found on maxillary teeth beside the hard palate. Surfaces that aid in chewing are known as occlusal on posterior teeth and incisal on anterior teeth. Surfaces nearest the junction of the crown and root are referred to as cervical, and those closest to the apex of the root are referred to as ...
Topical fluoride, such as a fluoride toothpaste or mouthwash, is also recommended to protect teeth surfaces. Many dentists include application of topical fluoride solutions as part of routine cleanings. Dental sealants are another preventive therapy often used to provide a barrier to bacteria and decay on the surface of teeth. Sealants can last ...
The uppercase letters A through T are used for primary teeth and the numbers 1 - 32 are used for permanent teeth. The tooth designated "1" is the maxillary right third molar ("wisdom tooth") and the count continues along the upper teeth to the left side. Then the count begins at the mandibular left third molar, designated number 17, and ...
Surfaces which form points of contact between adjacent teeth. [2] Axial A plane parallel to the surface of a tooth. For example, if a drill bur would be inserted into a tooth from any side (proximal, vestibular, oral), the depth of the hole is defined from the axial wall of the hole (from the long axis walls (vertical surfaces bounding the ...
On the mesial and distal surfaces, the cervical line curves incisally, which is also seen in the permanent maxillary central incisor. [citation needed] The root of this tooth is cone-shaped with a rounded apex. Most of the surfaces are smooth, but the mesial surface of the root may have a developmental groove or a concavity. [citation needed]
Human teeth are brachydont. [7] A brachydont tooth has a crown above the gingival line and a neck just below it, and at least one root. A cap of enamel covers the crown and extends down to the neck. Cementum is only found below the gingival line. The occlusal surfaces tend to be pointed, well-suited for holding prey and tearing and shredding. [10]
FDI Notation, teeth's quadrants FDI World Dental Federation notation (also "FDI notation" or "ISO 3950 notation") is the world's most commonly used dental notation (tooth numbering system). [ 1 ] [ 2 ] It is designated by the International Organization for Standardization as standard ISO 3950 "Dentistry — Designation system for teeth and ...
The teeth in the upper and lower jaws in mammals have evolved a close-fitting relationship such that they operate together as a unit. "They 'occlude', that is, the chewing surfaces of the teeth are so constructed that the upper and lower teeth are able to fit precisely together, cutting, crushing, grinding or tearing the food caught between."
