ABSTRACT
 Abrasion is damage to dental tissue due to foreign objects, such as toothbrushes and toothpastes that contain abrasive ingredients. Abrasion caused by brushing teeth in a horizontal direction and with excessive emphasis. This study aims to obtain an overview of the relationship between the characteristics and habits of brushing teeth with the incidence of dental abrasion in employees of the Al-Ikhlas Masjid Cilandak Foundation in Jakarta. This research is a descriptive study with a cross sectional design. The research sample used total sampling totaling 32 employees of Masjid Al

Abstract:
Non-carious cervical lesions (NCCLs) are saucer-shaped abrasions of a tooth. NCCLs can form due to various etiologies, including toothbrushing wear, acid erosion, and mechanical stress. Owing to this complex interplay, the mechanism of NCCLs in tooth abrasion has not been established. This study aims to develop a numerical method using a computational toothbrush to simulate NCCLs. The forces acting on the teeth and the amount of abrasion generated were evaluated. The discrete element method using in-house code, connected particle model, and Archard wear model were applied for brushing. In the

Relevance. Tooth abrasion is an inevitable consequence of their evolutionarily determined purpose of acquiring food through predation, detention, capture, grinding, chewing and swallowing. The mechanism of odontogenesis, according to which the amelogenesis of enamel ends with the death of ameloblasts before eruption, makes it impossible to recover enamel after damaging. Accordingly, any damage of any source is reflected on the hardest and oldest remains of creatures with teeth forever. Thus, tooth abrasion has a multifactorial origin and is based on diet and eating habits, oral hygiene, bruxis

Abstract:
Hypselodont (ever-growing) teeth of lagomorphs or rodents have higher wear rates (of a magnitude of mm/week), with compensating growth rates, compared to the non-ever-growing teeth of ungulates (with a magnitude of mm/year). Whether this is due to a fundamental difference in enamel hardness has not been investigated so far. We prepared enamel samples (n = 120 per species) from incisors of cattle (Bos primigenius taurus) and nutria (Myocastor coypus, hypselodont incisors) taken at slaughterhouses, and submitted them to indentation hardness testing. Subsequently, samples were split into 4 groups

The shorter service life of sizing crusher tooth is a difficult technology problem. At present the coal classification used in crushing machine, due to poor working conditions, despite the use of wear resistant surfacing electrode to improve the wear resistance of broken teeth, broken teeth, but not to the average life of six months, the subject of study was significantly improve the life of the crusher tooth. To improve the service life of sizing crusher tooth, some research has been done, through system analysis and test some result can be concluded.

One of the most frequent reasons for seeking dental care is discolored anterior teeth. Macroabrasion is a technique used for the removal of localized superficial white spots and other surface stains. This article has compiled three case reports with relevant clinical photographs of discolored teeth where the treatment regimen included macroabrasion alone as well as macro-abrasion in combination with anterior composite restorations.

In order to study wear behavior of enamel, dentine and two dental restorative composite materials scratch test at various contact conditions was employed. Hardness and elastic modulus were measured using nanoindentation with spherical and pyramidal indenters. Resid

The resistance to abrasive wear, scuffing, and pitting was investigated and reported in the article. Simple, model specimens were used.
