Dental caries (cavities), described as "tooth decay", is an infectious disease which damages the structures of teeth. [43] The disease can lead to pain, tooth loss, and infection. Dental caries has a long history, with evidence showing the disease was present in the Bronze, Iron, and Middle ages but also prior to the neolithic period. [44]
Universal Numbering System. Universal numbering system. This is a dental practitioner view, so tooth number 1, the rear upper tooth on the patient's right, appears on the left of the chart. The Universal Numbering System, sometimes called the "American System", is a dental notation system commonly used in the United States. [ 1][ 2]
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 .) Tooth formation begins before birth, and the teeth's eventual morphology is ...
The ASUDAS ( Arizona State University Dental Anthropology System) is a reference system for collecting data on human tooth morphology and variation created by Christy G. Turner II, Christian R. Nichol, and G. Richard Scott. [1] The ASUDAS gives detailed descriptions for common crown and root shape variants and their different degrees of expression.

The FDI World Dental Federation notation ("FDI notation" or "ISO 3950" [1]) is widely used by dental professionals internationally to identify and describe a specific tooth. The FDI notation uses a two-digit numbering system in which the first digit represents a tooth's quadrant and the second digit represents the number of the tooth from the ...
If tooth decay does occur (usually from trauma), dogs can receive dental fillings just as humans do. Similar to human teeth, the enamel of dogs is vulnerable to tetracycline staining. Consequently, this risk must be accounted for when tetracycline antibiotic therapy is administered to young dogs. [56] Enamel hypoplasia may also occur in dogs.
A 2021 study out of Japan showed how targeting genes can regrow teeth in animals. Now, the team has turned to a human clinical trial. By targeting the USAG-1 gene, researchers believe that they ...
