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, especially in elderly individuals.
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]
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.
Although it cannot cause periodontium damage in itself, [19] bruxism is known to be able to worsen attachment loss and tooth mobility if periodontal disease is already present. [20] Moreover, the severity of tooth mobility caused by bruxism also varies depending on the teeth grinding pattern and intensity of bruxism. [ 21 ]
The educational system [1] generally refers to the structure of all institutions and the opportunities for obtaining education within a country. It includes all pre-school institutions, starting from family education, and/or early childhood education, through kindergarten, primary, secondary, and tertiary schools, then lyceums, colleges, and faculties also known as Higher education (University ...
This article introduced the definition of abfraction as a "pathologic loss of hard tissue tooth substance caused by bio mechanical loading forces". This article was the first to establish abfraction as a new form of lesion, differing from abrasion , attrition , and erosion .
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.
Attrition (research), loss of participants during an experiment. Attrition (dental), loss of tooth structure by mechanical forces from opposing teeth; Attrition (erosion), the wearing away of rocks in rivers or the sea; Attrition, also known as Final Mission, 2018 american film; Imperfect contrition, also known as attrition, in Catholic theology
