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]
The evidence for linking malocclusion and/or crowding to dental caries is weak; [47] [48] however, the anatomy of teeth may affect the likelihood of caries formation. Where the deep developmental grooves of teeth are more numerous and exaggerated, pit and fissure caries is more likely to develop (see next section).
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 dictated
Pulp acts as a security and alarm system. Slight decay in tooth structure not extending to the dentin may not alarm the pulp, but as the dentin gets exposed, due either to dental caries or trauma, sensitivity starts. The dentinal tubules pass the stimulus to the pulp's odontoblastic layer, triggering the response. This mainly responds to cold.
This photo shows teeth #2-5 (Universal numbering system). Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay. This molar is both posterior, as well as distal, to the premolars in front of it. Most of the principal terms can be combined using their corresponding combining forms (such as mesio-for mesial and disto-for ...
The following outline is provided as an overview of and topical guide to dentistry and oral health: . Dentistry – branch of medicine that is involved in the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, maxillofacial area and the adjacent and associated structures and their impact on the human body.
Enamel hypoplasia is a risk factor for dental caries in children including early childhood caries (ECC), which continues to be a burden for many children. This association has been identified as significant and independent, and is believed that the formation of pits and missing enamel provides a suitable local environment for adhesion and ...
The high mineral content of enamel, which makes this tissue the hardest in the human body, also makes it demineralize in a process that often occurs as dental caries, otherwise known as cavities. [13] Demineralization occurs for several reasons, but the most important cause of tooth decay is the ingestion of fermentable carbohydrates.
