Teeth wear lesions are a common occurrence in our society, most especially, among the elderly group of patients. I just thought to share with you and I hope you find it useful 😊
What are the differences between these conditions?
ATTRITION : Attrition is the progressive loss of hard tooth substances caused by mastication or grinding between opposing teeth. The extent of attrition will depend upon the use to which an individual puts their teeth. For example, it will increase in people who habitually clench or grind their teeth (a condition known as bruxism), e.g., during sleep.
EROSION : Erosion is the progressive loss of tooth substance by chemical or acid dissolution, and no bacteria are involved. Erosion of tooth surfaces is mostly the results of too frequent or inappropriate use of carbonated drinks (including sparkling water) and fruit juices with high levels of acidity. This habit would appear to be particularly common amongst teenagers and young adults. Erosion is also a problem in individuals who suffer from gastrooesophageal reflux disease (GORD) or from certain eating disorders (e.g., anorexia, bulimia).
ABFRACTION : Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. Researchers have proposed that abfraction is caused by forces on the tooth from the teeth touching together, occlusal forces, when chewing and swallowing.
ABRASION : Abrasion is the progressive loss of hard tooth substances caused by mechanical actions other than mastication or tooth-to tooth contacts. Abrasion is commonly associated with incorrect toothbrushing technique, giving rise to notching at the junction of the crown and root of teeth. It will also be seen in individuals who use their teeth as a tool (e.g., to remove bottle tops, to hold pins, clips or nails). Enjoy your day!! Cc-dentalhealtheducation
