ABP Evaluations 3

Question 1

What is the primary purpose of calculating full-mouth bleeding score (FMBS) during a periodontal evaluation?

Accepted Answer

To assess gingival inflammation and treatment response

Answer

FMBS reflects the prevalence of gingival inflammation across all sites and is used to monitor treatment response and patient compliance.

Question 2

During evaluation of a patient for implant placement, which assessment finding most significantly increases the risk of peri-implantitis?

Accepted Answer

History of treated periodontitis with residual pockets ≥6 mm

Answer

A history of periodontitis, particularly with residual pockets, is the strongest risk factor for peri-implantitis due to shared bacterial reservoirs and host susceptibility.

Question 3

A clinician detects a 3-wall intrabony defect of 5 mm depth at tooth #30 mesial during re-evaluation post-SRP. What is the most appropriate next step?

Accepted Answer

Refer for regenerative surgical therapy

Answer

A 3-wall intrabony defect of 5 mm is an excellent candidate for guided tissue regeneration or bone grafting to restore lost periodontium.

Question 4

Which measurement method provides the most accurate quantification of clinical attachment level (CAL)?

Accepted Answer

Distance from the cementoenamel junction to the base of the sulcus/pocket

Answer

CAL is measured from the cementoenamel junction (CEJ) to the base of the periodontal pocket, reflecting true attachment loss independent of gingival margin position.

Question 5

When evaluating a patient for mucogingival surgery, what minimum width of keratinized tissue (KT) is generally considered sufficient to maintain periodontal health without surgery?

Accepted Answer

Any width if oral hygiene is adequate

Answer

Current evidence supports that adequate oral hygiene, not a specific minimum width of keratinized tissue, is the primary determinant of periodontal health at a site.
