The incidence of caries has declined; however, other dental lesions such as tooth wear are becoming increasingly important. Dental wear is a multifactorial process that may encompass erosion, abrasion, and combinations thereof. Therefore, various methodologies have been applied to evaluate the loss of dental hard tissue and the surface-softened zone in enamel induced by abrasive and erosive cha...

(1) Dental wear is a common phenomenon in mammals. Its occurrence is influenced by tooth anatomy, animal physiology, biomechanics and behaviour. So far, investigations of dental wear in cetaceans have been scanty and superficial. We compare the frequencies of occurrence, location and intensity of dental wear in some species of dolphins from southern Brazil, South Atlantic Ocean. (2) Teeth of te...

The present study aims to determine differences in vertical facial dimensions as a result of dental wear. The study consisted of 20 subjects with vertical tooth wear. The mean age of sample was 52.4 years. The control group consisted of 20 dental school students. The mean age of control group was 22 years (subjects with severe malocclusion or tooth wear were not included). All subjects’ cephalo...

Bariatric surgery may cause frequent vomiting episodes and gastroesophageal reflux, which promote the contact of gastric acids with the teeth leading to irreversible loss of tooth structure. The aim of this study was to assess prevalence of tooth wear in bariatric patients. One hundred and twenty-five patients were examined at a Public Hospital in São Luis, MA, Brazil, between July and October ...

One of the causes of abrasive wear is the use of abrasive tooth pastes and tooth brushes. This may lead to dentin sensitivity if exposed.The aim of this study is to examine 1,526 upper anterior and premolar teeth for evidence of abrasive wear. The segment of teeth were selected because of their preeminence in the smile line.1,526 upper anterior and premolar teeth were examined using key-feature...

Excessive occlusal wear can result in pulpal injury, occlusal disharmony, impaired function and aesthetic deformity. Loss of anterior guidance can result from severe wear of anterior teeth, which protects the posterior teeth during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension. This clinical repo...

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,...
