abstract the attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. this clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. the clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements, ge...

Severe tooth wear is the most common non-caries dental disease, and it can seriously affect oral health. Studying the tooth wear process is time-consuming and difficult, and technological tools are frequently lacking. This paper presents a novel method of digital simulation modeling that represents a new way to study tooth wear. First, a feature extraction algorithm is used to obtain anatomical...

Tooth wear and its rehabilitation is a much discussed and studied subject in dentistry. The increased life expectancy may be one of the factors that it has become more ubiquitous. Often patients with tooth wear report to the dental clinic requiring extensive restorative treatment. Wear can be the result of attrition, abrasion, erosion or abfraction. The clinical presentation may vary and can be...

A study of the degree and gradient of attrition was undertaken on 352 molar teeth of 88 selected Nigerian subjects. A method for the quantification of attrition experience per molar tooth is described. There is a close correlation between age and the degree of attrition of the first molar. This finding may be of value in age determination in forensic odontology. The wear on the first molar is a...

Tooth wear is a universal experience. The cause is usually a combination of erosion, attrition and abrasion. Attrition usually presents with flattened incisal and occlusal tooth surfaces which accurately inter-digitate. Erosion from dietary or gastric acids forms smooth lesions which typically appear as cupped occlusal/incisal and concave buccal/facial surfaces. When combined with attrition or ...

OBJECTIVES Attrition and occlusal factors and masticatory function or dysfunction are thought to be related. This study aims to systematically review the literature on this topic with the emphasis to find evidence for occlusion-based treatment protocols for attrition. MATERIALS AND METHODS Literature was searched using PubMed (1980 to 2/2006) and the Cochrane Library of Clinical Trials with t...

Attrition, erosion, and abrasion result in alterations to the tooth and manifest as tooth wear. Each classification corresponds to a different process with specific clinical features. Classifications made so far have no accurate prevalence data because the indexes do not necessarily measure a specific etiology, or because the study populations can be diverse in age and characteristics. Tooth we...

Occlusal wear is most often attributed to attrition, which is defined as the wearing away of one tooth surface by another tooth surface. However, there are several etiological factors that can result in excessive loss of tooth structure. Common factors are enumerated as congenital anomalies, parafunctional occlusal habits, abrasion, erosion or loss of posterior tooth support.1 Tooth wear can al...

Accessory cusps are common variations of tooth morphology that are occasionally seen clinically. Most commonly occurs in Asians. While its presence may not be a cause for alarm in most instances, it can sometimes lead to serious consequences if it is damaged. This article will highlights the various types of dens evaginatus, and periodic dental surveillance, which include monitoring of the degr...
