Study Notes

Tooth Wear Overview

Tooth wear is a common clinical finding, increasing in prevalence with age, with 3% of 20-year-olds and 17% of 70-year-olds exhibiting severe tooth wear.
Males tend to experience greater tooth wear than females, possibly due to increased tooth retention and greater occlusal forces.
Tooth wear is normal, physiologically increasing with age, but may become pathologically significant secondary to a parafunctional habit.

Types of Tooth Wear

Abrasion: physical wear caused by materials other than tooth contact.
Abfraction: tooth wear located in the cervical region leading to erosion.

Prevalence of Tooth Wear

53% of adolescents and 77% of adults in the UK have dental erosion.
Severe wear (exposing secondary dentine) remained at 2%.
Tooth wear is most common on the palatal surfaces of maxillary incisors in children of all socio-economic backgrounds.

Causes of Tooth Wear

Chronic alcoholism: both extrinsic and intrinsic dental erosion.
Environmental erosion: improvements in health and safety have been developed, such as wearing protective airways masks.
Self-induced vomiting in patients with eating disorders (e.g., bulimia).

Diagnosis and Treatment

The diagnosis of parafunctional activity is difficult, and patients themselves are often not aware of the condition.
Perimolysis lesions (erosive lesions on the palatal surfaces of maxillary incisors) are a common sign of parafunctional activity.
Treatment involves reducing the effects of the erosive source, and alternative methods include using intra-oral three-dimensional laser scanners, sequential photographs, and periodic accurate study casts.
Appropriate toothbrushing advice and habit avoidance or counselling will also be of benefit to the patient.
