Lesions affect the facial aspect of the teeth have their drawbacks on the individual psychological status. Abfraction affects the gingival third of the teeth on the facial surface. It mainly affects premolars and anterior teeth. Bacteria have no role in abfraction, so it may affect individuals ...
Throughout the years, the dental profession has held a variety of theories about the causes of tooth wear, including chemical wasting of the teeth, the effects of tooth brushing, and lateral forces. Tooth wear may present as abfraction, abrasion, attrition, and erosion. It is well established...
Examination of ancient skeletal remains have not found such tooth lesions although the teeth show occlusal wear. In support of the process of abfraction, cervical enamel is more brittle than dentine and there is poorly developed scalloping between this and dentine in this region. This has to ...
Abfraction is thought to take place when excessive cyclic, non-axial tooth loading leads to cusp flexure and stress concentration in the vulnerable cervical region of teeth. Such stress is then believed to directly or indirectly contribute to the loss of cervical tooth substance. This article ...
The aim of this study was to examine what effect undermining of the buccal cervical enamel would have on the stress distribution in upper teeth. Two-dimensional plain strain finite element meshes of an upper incisor, canine and first premolar and the supporting periodontal ligament and alveolar ...
Twelve models were generated: sound tooth, 1·25 and 2·5 mm abfraction teeth. 100N compressive static load was applied: axially and 45° angle to the long axis on the palatine surface of the buccal cusp. Two strain gauges were bonded on the teeth mounted in a mechanical testing ...
An overall of 6629 teeth are investigated to find NCCLs and wear facets. The occlusion is analyzed in each patient. Results: An overall of 801 teeth (12%) show NCCLs and 623 of them (78%) highlight also wear facets. The higher number of teeth with NCCLs and of these with simultaneous...
The teeth were randomly assigned according to dentin treatment: 0.02% EGCG solution or distilled water (control). After enamel acid etching, the solutions were applied immediately for 1 minute. The teeth were restored with Universal Adhesive (3M) and Filtek Z350 XT (3M). Analyzes were done by...

Statement of problem It is unclear whether subjects who report tooth clenching and/or grinding have more noticeable clinical signs of dental attrition, abfractions, and occlusal pits on their natural teeth than subjects who do not report bruxism activity. Purpose The purpose of this study was to ...
