The aetiology of dental abrasion can be due to a single stimulus or, as in most cases, multi-factorial. [6] The most common cause of dental abrasion is the combination of mechanical and chemical wear. Tooth brushing is the most common cause of dental abrasion, which is found to develop along the gingival margin, due to vigorous brushing in this ...
Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel , especially at the cementoenamel junction (CEJ), undergoes large amounts of stress ...
Abfraction is a form of noncerious cervical lesion, where there is a loss of tooth substance at the cervical margins, purportedly caused by minute flexure of teeth under occlusal loading. This occlusal loading is one factor that interacts with chemical, biological,and behavioral factors in which result in this abfraction.
Non-carious cervical lesions on an incisor belonging to Australopithecus africanus. Arrows show the location of the lesions. Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes.

Wedge-shaped cervical lesions are commonly found in association with occlusal erosion and attrition. [9] Tooth wear is typically seen in the elderly and can be referred to as a natural aging process. Attrition, abrasion, erosion or a combination of these factors are the main reasons for tooth wear in elderly people who retain their natural teeth.
Receding gums can be a sign of long-term trauma from excessive or forceful toothbrushing or abrasive toothpaste (dental abrasion), or a sign of chronic periodontitis (gum disease). [10] A less common cause is acid erosion , which is the loss of hard dental tissues due to acids e.g. related to gastroesophageal reflux disease , bulimia or ...
External cervical resorption is a localised resorptive lesion in the cervical area of the tooth, below the epithelial attachment. It is distinguished from external inflammatory root resorption in that it rarely involves the pulp. When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption.
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
