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. Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. [ 3 ]
The pathological wear of the tooth surface can be caused by bruxism, which is clenching and grinding of the teeth. If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity .
The primary cause of enamel wear in the grooves is the direct mechanical forces applied during chewing, such as vertical pressure and lateral forces as teeth grind or shear food. Particularly in areas where food is more frequently trapped or where contact is poor, the continuous friction between the food and the tooth surface causes abrasion ...
Demineralization occurs for several reasons, but the most important cause of tooth decay is the ingestion of fermentable carbohydrates. [citation needed] Tooth cavities are caused when acids dissolve tooth enamel: [22] Enamel is also lost through tooth wear and enamel fractures. [23] Ca 10 (PO 4) 6 (OH) 2 (s) + 8H + (aq) → 10Ca 2+ (aq) + 6HPO ...
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]
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, causing micro fractures and tooth tissue loss. Abfraction appears to be a modern condition, with examples of non-carious cervical ...
The white opaque areas in the enamel of the teeth are more extensive but do involve as much as 50% of the tooth. Moderate: 4: All enamel surfaces of the teeth are affected and surfaces subject to attrition show wear. Brown stain is frequently a disfiguring feature Severe: 5: All enamel surfaces are affected and hypoplasia is so marked that the ...
Nevertheless, the AI affect primary and permanent teeth leading to various forms of enamel defects like hypomineralization and hypocalcification and the affected teeth appear discolored, brittle and highly prone to wear [32], as the severity and appearance of the defects is based on the specific gene mutation with certain forms resulting in ...
