Attrition, abrasion, erosion or a combination of these factors are the main reasons for tooth wear in elderly people who retain their natural teeth. This tooth wear can be pathological or physiological. [10] The number of teeth with incisal or occlusal wear increases with age. [11] [12] Attrition occurs in 1 in 3 adolescents. [12]
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 ...
Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. [3] However, tooth wear is often a combination of the above processes. Many clinicians, therefore, make diagnoses such as "tooth wear with a major element of attrition", or "tooth wear with a major element of erosion" to reflect ...
This article was the first to establish abfraction as a new form of lesion, differing from abrasion, attrition, and erosion. [2] Tooth tissue is gradually weakened causing tissue loss through fracture and chipping or successively worn away leaving a non-carious lesion on the tooth surface.
Acid erosion often coexists with abrasion and attrition. [12] Abrasion is most often caused by brushing teeth too hard. [3] Any frothing or swishing acidic drinks around the mouth before swallowing increases the risk of widespread acid erosion. [12] Sucking citrus fruits can also contribute to acid erosion. [11]
Attrition is the loss of tooth structure by mechanical forces from opposing teeth. [66] Attrition initially affects the enamel and, if unchecked, may proceed to the underlying dentin. Abrasion is the loss of tooth structure by mechanical forces from a foreign element. [67]
3. Plan your withdrawal strategy. Most retirement strategies plan for saving, not spending. So it’s not always easy to remember that there will come a time you have to spend the money you’ve ...
Permanent (adult) teeth are not discoloured, or the discolouration is mild (grey colour). Little or no attrition (tooth wear) is evident. The crown of the teeth may be bulbous and markedly constricted at the cemento-enamel junction (CEJ). Radiographically, evidence of partial pulp obliteration with a "thistle-shaped appearance". [3]
