Question

a periodontal reading of 2 mm means:
a the tooth will be lost
b the gum is inflamed
c the patient does not floss
d the tooth and gum are normal

Explanation:

In periodontology, a periodontal probing depth of 2 mm is within the normal range (typically 1 - 3 mm for healthy gums and teeth). Option A is incorrect as 2 mm doesn't indicate tooth loss. Option B is wrong because gum inflammation (gingivitis/periodontitis) is associated with deeper pockets (usually >3 mm) or other signs, not a 2 mm reading. Option C is incorrect as flossing habits can't be determined from a single periodontal reading. Option D aligns with the normal range for periodontal probing.

Answer:

D. The tooth and gum are normal
