ABP Maintenance Protocols 3

Question 1

Which of the following local risk factors most significantly compromises periodontal maintenance outcomes?

Accepted Answer

Furcation involvements class II or III

Answer

Class II or III furcation involvements harbor biofilm that is difficult to instrument, making them major local risk factors for maintenance failure.

Question 2

The Periodontal Risk Assessment (PRA) model developed by Lang and Tonetti uses which parameter to stratify maintenance patients into risk categories?

Accepted Answer

Attachment loss rate, bleeding on probing %, environmental/systemic factors

Answer

The PRA model integrates rate of attachment loss, percentage of bleeding on probing, number of residual pockets, bone loss/age ratio, systemic factors, and smoking to determine risk.

Question 3

A maintenance patient who smokes is LEAST likely to show which of the following clinical signs compared to a non-smoker with equivalent disease?

Accepted Answer

Bleeding on probing

Answer

Smoking causes vasoconstriction that masks gingival bleeding, so smokers show less bleeding on probing despite active disease.

Question 4

Chemotherapeutic adjuncts such as locally delivered doxycycline (Atridox) during maintenance are MOST appropriately used in:

Accepted Answer

Isolated, non-responsive pockets ≥5 mm with active disease

Answer

Locally delivered antibiotics are best reserved for isolated non-responding pockets ≥5 mm showing signs of active disease during maintenance.

Question 5

Which of the following best characterizes 'supportive periodontal therapy' (SPT) as distinct from standard prophylaxis?

Accepted Answer

SPT includes full-mouth periodontal debridement and individualized risk assessment

Answer

SPT involves comprehensive periodontal assessment, individualized risk evaluation, and subgingival debridement as needed—far beyond a routine prophylaxis.
