    Study Notes

    Tooth Wear Quiz

    • BEWE score of 18 indicates more than 50% tooth wear in each sextant.
    • Clinical signs of dental erosion include:
      • Scooped out lesions on occlusal surfaces of molars and premolars
      • Labial surface lesions on maxillary incisors
    • Dental erosion is caused by acid dissolution, often affecting labial surfaces of upper front teeth (due to dietary or gastric acid exposure).
    • Dental abrasion is tooth wear from mechanical actions (improper brushing, using toothpicks excessively, chewing on hard objects).
    • Dental attrition is tooth wear from tooth-to-tooth contact (such as grinding or clenching).
    • Dentine hypersensitivity occurs when the protective layers of enamel or cementum are lost, exposing the underlying dentine and its tubules. Exposure results from active tooth wear.
    • Preventing dental erosion includes recommendations to limit acidic food and drink consumption to three or fewer times a day, and avoiding brushing teeth within 10 minutes of consuming acids.
    • BEWE (Basic Erosive Wear Examination) is a tool clinicians use to assess and score the severity of erosive tooth wear across the mouth. This helps evaluate extent of the damage and monitor progression.
    • Critical pH of enamel is 5.5. Below this pH, demineralization of enamel begins, resulting in tooth structure loss.
    • Fluorapatite is a more resistant form of enamel formed by incorporating fluoride. This lowers the critical pH at which enamel demineralizes.
    • Tooth wear prevalence increases with age.
    • Tooth wear is not reversible.
    • Tooth wear is often a combination of dental erosion, abrasion, and attrition,
    • BEWE score of 2: indicates less than 50% loss of tooth structure.
    • BEWE score of 3: indicates more than 50% loss of tooth structure.

    Salivary Factors

    • Stimulated saliva has a higher flow rate, contains bicarbonate, which neutralizes acids, protecting teeth from demineralization.
    • A reduced quantity and quality of saliva exposes teeth to acids, leading to potential tooth wear.
