Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
The word attrition is derived from the Latin verb attritium, which refers to the action of rubbing against something. [2] Attrition mostly causes wear of the incisal and occlusal surfaces of the teeth. Attrition has been associated with masticatory force and parafunctional activity [2] such as bruxism. A degree of attrition is normal ...
The teeth most likely affected are the maxillary anterior teeth, but all teeth can be affected. [95] The name for this type of caries comes from the fact that the decay usually is a result of allowing children to fall asleep with sweetened liquids in their bottles or feeding children sweetened liquids multiple times during the day.
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]
Tooth wear is another key feature of dental remains that can be analysed to infer past diets. Wear that is the result of natural contact between upper and lower teeth is called attrition, and wear that is the result of external objects like food coming into contact with the teeth is called abrasion. [29]
Dental fluorosis is a common [2] disorder, ... All enamel surfaces of the teeth are affected and surfaces subject to attrition show wear. Brown stain is frequently a ...
The agents most commonly used to intrinsically change the color of teeth are hydrogen peroxide and carbamide peroxide. Oxygen radicals from the peroxide in the whitening agents contact the stains in the interprismatic spaces within the enamel layer. When this occurs, stains will be bleached and the teeth now appear lighter in color.
Overerupted teeth are often sharp due to lack of tooth wear (dental attrition) by adjacent teeth during chewing. [ citation needed ] Overeruption is treated either by forcing the tooth back using orthodontic techniques, or by cutting the interfering part of the tooth and installing a crown .
