Accepted Answer

Leukoplakia

Answer

Leukoplakia is a white patch that cannot be scraped off and is considered a potentially malignant disorder requiring biopsy to rule out dysplasia.

Question 3

Which clinical parameter is considered the gold standard for diagnosing active periodontal disease progression?

Accepted Answer

Clinical attachment loss (CAL)

Answer

Clinical attachment loss (CAL) is the gold standard for diagnosing periodontal disease, as it measures the actual loss of the tooth's supporting structures from the CEJ.

Question 4

A dental hygienist records a gingival recession of 2 mm and a probing depth of 4 mm. What is the clinical attachment loss (CAL)?

Accepted Answer

6 mm

Answer

CAL is calculated by adding probing depth to recession: 4 mm + 2 mm = 6 mm, indicating 6 mm of total attachment loss.

Question 5

Which of the following best defines a sinus tract (formerly called a fistula) on clinical examination?

Accepted Answer

A channel through soft or hard tissue that drains a chronic abscess

Answer

A sinus tract is a channel or pathway through tissue that provides drainage for a chronic periapical or periodontal abscess, often appearing as a small opening on the gingiva.
