CPT Supportive Periodontal Therapy & Maintenance 2

Question 1

What is the PRIMARY goal of supportive periodontal therapy (SPT)?

Accepted Answer

To maintain the clinical results of active therapy and prevent disease recurrence

Answer

The primary goal of SPT is to preserve the clinical improvements achieved during active periodontal therapy and prevent reactivation of the disease.

Question 2

Which systemic condition most commonly necessitates more frequent SPT recall intervals?

Accepted Answer

Poorly controlled diabetes mellitus

Answer

Poorly controlled diabetes impairs immune function and wound healing, significantly increasing susceptibility to periodontal recurrence and requiring shorter SPT recall intervals.

Question 3

During an SPT visit, bleeding on probing (BOP) is found at 30% of sites. This finding most likely indicates:

Accepted Answer

Active gingival inflammation requiring reinforced oral hygiene instruction and possible interval adjustment

Answer

BOP above 10% of sites indicates persistent gingival inflammation and signals the need for improved oral hygiene instruction and consideration of shorter recall intervals.

Question 4

Which bacteria are MOST strongly associated with recurrent periodontitis during SPT?

Accepted Answer

Porphyromonas gingivalis and Tannerella forsythia

Answer

P. gingivalis and T. forsythia are key members of the 'red complex' and are the primary pathogens driving periodontitis progression and recurrence during SPT.

Question 5

What is the MOST effective method to detect bone level changes over time during SPT?

Accepted Answer

Sequential standardized periapical radiographs compared to post-treatment baseline images

Answer

Standardized periapical radiographs taken with the paralleling technique allow accurate comparison to baseline images to detect subtle interproximal bone changes over time.
