ABP Non-Surgical Therapy 2

Question 1

Which systemic condition is most strongly associated with increased susceptibility to periodontal disease and poorer response to non-surgical therapy?

Accepted Answer

Poorly controlled type 2 diabetes

Answer

Poorly controlled diabetes impairs neutrophil function and collagen synthesis, leading to increased periodontal destruction and reduced response to non-surgical therapy.

Question 2

During SRP of a deep furcation-involved molar, which instrument is most effective for debridement of the furcation fornix?

Accepted Answer

Furcation curette (e.g., Younger-Good 7/8)

Answer

Furcation-specific curettes such as the Younger-Good 7/8 have angled shanks designed to access and debride the concave furcation fornix effectively.

Question 3

What is the primary goal of subgingival debridement during non-surgical periodontal therapy?

Accepted Answer

Disruption of the subgingival biofilm and removal of calculus

Answer

The primary goal is disruption and removal of the subgingival biofilm and calculus to reduce the microbial challenge and allow host healing.

Question 4

Which antimicrobial agent used as an adjunct to SRP works primarily by disrupting bacterial cell membranes and denaturing proteins?

Accepted Answer

Chlorhexidine

Answer

Chlorhexidine is a cationic bisbiguanide that disrupts bacterial cell membranes and denatures intracellular proteins, providing broad-spectrum antibacterial activity.

Question 5

A patient presents with generalized Stage III Grade C periodontitis and is a current smoker. Which statement best describes the expected treatment outcome after SRP?

Accepted Answer

Smokers show significantly less clinical attachment gain and pocket reduction

Answer

Smoking impairs neutrophil chemotaxis, reduces gingival blood flow, and blunts the inflammatory response, leading to significantly reduced clinical gains after SRP compared to non-smokers.
