attritie

Attritie is the Dutch term for attrition and is used in several fields to describe a gradual loss, wearing away, or reduction. In Dutch-language texts it may refer to physical wear, demographic change, or turnover, depending on context. In other languages the corresponding term is attrition.

In dentistry, attritie refers to tooth wear caused by teeth grinding or by tooth-to-tooth contact during chewing and biting. It typically affects occlusal and incisal surfaces and can be influenced by bruxism, diet, and jaw alignment. It is differentiated from abrasion (wear caused by foreign substances) and erosion (chemicalwear from acids).

In materials engineering, attrition describes material removal due to mechanical action such as rubbing, sliding contact, or particle impact, leading to gradual loss of material or changes in surface properties. It is one form of wear alongside abrasion and fatigue wear; factors include load, speed, temperature, lubrication, and hardness of the engaging surfaces.

In human resources and marketing, attrition denotes the loss of customers or employees over time; the attrition rate is the number of losses during a period divided by the number at the start. Causes include voluntary departure, retirement, or natural churn. Organizations monitor attrition to gauge stability and to inform retention or acquisition strategies.

In military theory, attrition warfare emphasizes reducing an opponent's combat effectiveness through sustained losses rather than seeking a swift, decisive victory. In longitudinal research, attrition describes participant dropout, which can bias results; methods to mitigate include follow-up efforts, statistical weighting, and imputation.
