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.
Tooth wear varies substantially between people and groups, with extreme attrition and enamel fractures common in archaeological samples, and erosion more common today. [3] [4] [5] Tooth wear is predominantly the result of a combination of three processes; attrition, abrasion and erosion. [3]
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity ; [ 1 ] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [ 2 ]
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
"Cats right now have a 67 percent mortality rate," she noted. Forbes said that canned and kibbled food is considered safe if it has been cooked. But if the kibble is coated with raw meat, "I would ...
The cause is the chronic parafunctional activity of the masticatory system, which produces frictional, crushing, and incisive damage to the mucosal surface, and over time, the characteristic lesions develop.
But if that’s not possible, I’m not going to apologize for my full-fat recipes.” This, Albright explains, is “the enactment of a value.” “There’s a tension between health and ...
Video of a cat purring. The purr is a continuous, soft, vibrating sound made in the throat by most species of felines. [8] However, the reason why cats purr is still uncertain. Cats may purr for a variety of reasons, including when they are hungry, happy, or anxious. [9]
