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...
The analysis of these studies, which correlated the progression of NCCLs to the forces applied to the teeth, did not provide sufficient evidence to confirm or refute the aetiological role of occlusal loads in the onset of abfractions. However, clues emerged that would require further confirmation ...
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 ...
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 ...
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 ...
These non‐carious processes may include abrasion, corrosion and possibly abfraction, acting alone or in combination. 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 ...
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...
