Study Notes
Dental Wear: Types and Clinical Manifestations
- Bruxism is the dynamic grinding of teeth, while clenching is the static contact of teeth together as power from the closing muscles of the jaw is applied.
- The most affected surfaces from bruxism are the occlusal and incisal ones, leading to flat, glossy lesions with distinct margins.
- Dentine wear accelerates as dentine tends to be removed two to five times quicker than enamel in bruxist patients.
- Intrinsic erosion affects the palatal surfaces of maxillary anterior teeth, while extrinsic erosion results in widespread cupped out lesions, impacting specific tooth areas.
- Abrasion presents as localized lesions, matching the shape of the object when an object is held between the teeth.
- Abrasive wear usually presents sharp defined margins, distinguishing it from erosive wear.
- Abfraction manifests as wedge-shaped defects at the level of the cementoenamel junction, resembling abrasive wear but with a more angular aspect.
- Dentists should inquire about diet, habits, and oral hygiene techniques to determine the etiology of wear.
- The Tooth Wear Index (TWI) evaluates tooth surfaces based on the loss of enamel, dentine, and contour changes.
- Basic Erosive Wear Examination (BEWE) registers the status of the most affected surface of each tooth and the most affected tooth of each sextant.
- Preventive measures for dental wear include monitoring, dietary advice, medical referral, oral hygiene education, and suppression of bad habits.
- The decision to treat dental wear is based on classification, severity of wear, and patient symptoms, with preventive or restorative approaches recommended based on the findings.
