What does a BEWE score of 18 indicate?

A BEWE score of 18 indicates a significant amount of tooth wear throughout the mouth, suggesting a need for further investigation and potential treatment.

What is dental erosion?

Erosion is a form of tooth wear caused by the chemical breakdown of enamel by acids, often from dietary sources or gastric reflux.

What is a common sign of dental erosion?

Labial surface lesions, especially on the maxillary incisors, are a common sign of dental erosion, often caused by exposure to acidic foods or beverages or gastric reflux.

What are scooped-out occlusal lesions a sign of?

Scooped-out lesions on the occlusal surfaces of molars and premolars are a characteristic sign of erosion, resulting from the gradual wearing away of tooth structure by acids.

How can improper toothbrushing cause abrasion?

Improper toothbrushing techniques, such as brushing too hard or using abrasive toothpaste, can contribute significantly to dental abrasion, leading to wear on tooth enamel.

How can using toothpicks cause abrasion?

Excessive use of toothpicks can lead to dental abrasion, especially around the gum line, as the sharp edges scrape away tooth enamel.

How can chewing on hard objects cause abrasion?

Chewing on pens or other hard objects can cause dental abrasion, especially on the incisal edges of teeth, as the constant pressure and friction wear away tooth structure.

What does a BEWE sextant score of 2 indicate?

In the Basic Erosive Wear Examination (BEWE), a sextant score of 2 signifies that less than 50% of the tooth structure is lost within a specific sextant. This represents moderate erosive wear, characterized by distinct defects that haven't yet extended to encompass more than half of the tooth surface.

What does a BEWE sextant score of 3 indicate?

When more than 50% of the tooth structure within a sextant is lost, a BEWE sextant score of 3 is assigned. This represents severe erosive wear, where significant damage has occurred across the tooth surfaces.

When to brush after an acidic attack?

Brushing teeth too soon after an acidic attack can worsen enamel erosion. It's best to wait at least 30-60 minutes for the enamel to remineralize.

Do fruits always promote good oral health?

While fruits are healthy, acidic fruits like citrus can contribute to enamel erosion if consumed excessively. It's important to have a balanced diet.

Are salt water rinses effective for neutralizing acid?

Salt water rinses, while they might soothe, don't neutralize acid effectively. Alkaline rinses, like those with bicarbonate, are better for neutralizing acids.

Is tooth wear reversible?

Tooth wear is not reversible because lost enamel and dentin cannot be regrown. We can't simply 'undo' the damage.

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.
