Flashcards

What does a BEWE score of 18 mean?

A BEWE score of 18 indicates severe tooth wear, with more than 50% tooth wear in each of the six tooth sections (sextants) of the mouth.

What is dental erosion?

Dental erosion is the loss of tooth structure due to chemical processes, primarily caused by acids.

What is a sign of dental abrasion?

Smooth, flat facets on the occlusal surfaces of posterior teeth are a sign of dental abrasion.

What is a clinical sign of dental erosion?

Scooped-out lesions on the occlusal surfaces of the first permanent molars are a clinical sign of dental erosion.

What is another clinical sign of dental erosion?

Labial surface lesions on the maxillary incisors are a clinical sign of dental erosion.

What is dental abrasion caused by?

Dental abrasion is tooth wear caused by frequent exposure to objects or factors other than teeth or acids, like brushing with excessive force or chewing on hard objects.

What does dentine hypersensitivity indicate?

Dentine hypersensitivity, especially if dentine is exposed, indicates active tooth wear, implying that the process of tooth wear is ongoing.

What are some measures for preventing dental erosion?

To prevent dental erosion, limit acid consumption to three or less times per day. Avoid brushing teeth for 10 minutes after consuming acidic drinks or foods.

Study Notes

BEWE Score Interpretation

  • A BEWE score of 18 indicates severe tooth wear, with more than 50% tooth loss in each sextant.

Clinical Signs of Dental Erosion

  • Smooth, flat facets on posterior teeth occlusal surfaces are a sign.
  • Scooped-out lesions on the first permanent molars' occlusal surfaces are another sign.
  • Labial surface lesions on maxillary incisors are also indicative.

Dental Abrasion Causes

  • Frequent exposure to non-acidic, non-tooth objects (e.g., abrasive materials) causes abrasion. This is not caused by acids.

Dentine Hypersensitivity and Tooth Wear

  • Exposed dentin signifies active tooth wear, not stable wear.

Dietary Advice for Preventing Dental Erosion

  • Limiting acid consumption to a maximum of 3 times a day. This is important for prevention.

BEWE Sextant Scoring

  • A score of 2 indicates less than 50% loss of tooth structure in a sextant.
  • A score of 3 indicates more than 50% loss of tooth structure in a sextant.

Tooth Wear Factors

  • Tooth wear results from a combination of erosion, abrasion, and attrition.
  • Tooth wear prevalence increases with age.
  • Tooth wear is typically not reversible.
  • Tooth wear can be external (e.g., acid exposure) or internal (e.g., acids produced by bacteria).
  • Early detection is difficult.

BEWE Acronym Explanation

  • BEWE stands for Basic Erosive Wear Examination.

Enamel's Critical pH

  • Enamel's critical pH is 5.5.

Fluoride and Enamel Critical pH

  • Fluoride incorporation lowers the enamel's critical pH.

BEWE Tool Purpose

  • The primary function of the BEWE tool is screening for tooth wear.

Tooth Wear and Age

  • Tooth wear prevalence is linked to age, increasing with advancing years.

Dental Attrition Definition

  • Tooth-to-tooth contact is the primary factor in attrition.

Assessing Tooth Wear Risk

  • Evaluating wear rate and severity relative to a patient's age is critical.
  • Examining exposed dentin is important.

Minimum BEWE Score for Exposed Dentin

  • A BEWE score of 2 is the minimum for a sextant with exposed dentin.

BEWE Score for No Tooth Wear

  • A BEWE score of 0 indicates no detectable tooth wear.

Salivary Factors and Tooth Wear Protection

  • Saliva's buffering action from stimulated production neutralizes oral acids; it protects teeth.
  • Reduced saliva quality and quantity can expose teeth to acids, increasing tooth wear risk.
