NBDHE NBDHE Periodontal Assessment and Treatment 5

Question 1

Following scaling and root planing, re-evaluation is typically performed after how many weeks?

Accepted Answer

4-6 weeks

Answer

Re-evaluation is typically scheduled 4-6 weeks after SRP to allow tissue healing and reassess pocket depths, bleeding, and need for additional treatment.

Question 2

A patient has generalized probing depths of 5-7 mm, Grade C periodontitis. Which systemic antibiotic regimen is most supported by evidence as an adjunct to SRP?

Accepted Answer

Amoxicillin 500 mg + metronidazole 500 mg three times daily for 7 days

Answer

The amoxicillin and metronidazole combination targets both aerobic and anaerobic periodontal pathogens and has the strongest evidence as a systemic adjunct to SRP in aggressive/Grade C periodontitis.

Question 3

What is the primary purpose of root planing during SRP?

Accepted Answer

Remove cementum containing endotoxins and create a smooth, hard surface to promote tissue reattachment

Answer

Root planing removes contaminated cementum containing bacterial endotoxins and creates a clean, smooth root surface that promotes reattachment of connective tissue fibers.

Question 4

Which of the following best describes 'pseudopockets' (false pockets)?

Accepted Answer

Increased sulcus depth caused by coronal enlargement of gingiva without apical migration of junctional epithelium

Answer

Pseudopockets result from gingival enlargement (tissue swells coronally) rather than apical migration of attachment; they represent increased probing depth without true attachment loss.

Question 5

What is the recommended width of keratinized gingiva needed to maintain periodontal health around natural teeth?

Accepted Answer

At least 2 mm of keratinized gingiva (1 mm attached)

Answer

Most consensus statements recommend a minimum of 2 mm of keratinized gingiva (with at least 1 mm attached) to withstand masticatory forces and maintain health around natural teeth.
