What dental issue does abfraction describe?
Excessive tartar buildup
Loss of tooth surface in the cervical area
Discoloration of teeth
Development of cavities
The correct answer is: Loss of tooth surface in the cervical area
Abfraction refers to the loss of tooth structure at the cervical area, where the tooth meets the gum line. This phenomenon is caused by a combination of biomechanical forces that lead to the bending of teeth, resulting in microfractures and the subsequent wearing away of enamel and dentin. The cervical region is particularly vulnerable to this issue due to the stresses applied during normal biting and chewing. Understanding abfraction is crucial in dentistry because it can lead to sensitivity, increased risk for caries, and potential aesthetic concerns if not addressed. Identifying this specific type of tooth erosion can help dental professionals develop effective treatment plans to protect and restore tooth integrity in affected patients.
