Tooth wear is predominantly the result of a combination of three processes; attrition, abrasion and erosion. [3] These forms of tooth wear can further lead to a condition known as abfraction , [ 3 ] where by tooth tissue is 'fractured' due to stress lesions caused by extrinsic forces on the enamel.
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
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 ...
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain.One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament."
Acid erosion is a type of tooth wear. It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
Internal resorption is defined by the loss of intraradicular dentin and tubular dentin from within the middle and apical thirds of the root canal(s). It may also present as an incidental, radiographic finding. Radiographically, a radiolucent area of uniform density within the root canal may be visible with well-defined borders.
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
