ABP Treatment Planning 3

Question 1

A patient presents with localized aggressive periodontitis (Stage III Grade C, molar-incisor pattern). Which adjunctive therapy is most supported by evidence?

Accepted Answer

Systemic amoxicillin plus metronidazole combined with SRP

Answer

Combining systemic amoxicillin (500mg TID) and metronidazole (500mg TID) with SRP has the strongest evidence for Grade C molar-incisor pattern periodontitis due to Aggregatibacter actinomycetemcomitans.

Question 2

Which classification system, adopted by the 2017 World Workshop, is currently used to classify periodontal diseases for treatment planning?

Accepted Answer

2017 staging and grading system (Stage I-IV, Grade A-C)

Answer

The 2017 World Workshop classification replaced prior systems, using a staging (I-IV) and grading (A-C) framework that incorporates complexity factors and risk modifiers.

Question 3

A patient with end-stage renal disease on dialysis requires periodontal treatment. Which planning consideration is most critical?

Accepted Answer

Coordinating treatment on non-dialysis days and checking drug dosing due to altered clearance

Answer

Renal patients have altered drug clearance and bleeding tendencies (post-dialysis heparin effect), so treatment is best scheduled the day after dialysis with appropriate drug dosing adjustments.

Question 4

In treatment planning for a patient with gingival enlargement due to amlodipine (a calcium channel blocker), what is the first recommended step?

Accepted Answer

Consult with the prescribing physician about substituting the medication

Answer

Drug substitution (e.g., changing to another antihypertensive) combined with meticulous plaque control can lead to significant regression of drug-influenced gingival enlargement before considering surgery.

Question 5

When evaluating a patient for periodontal implant therapy, which factor represents an absolute contraindication to implant placement?

Accepted Answer

Active head and neck radiation therapy field

Answer

Active irradiation of the jaw is an absolute contraindication due to severely compromised vascularity and high risk of osteoradionecrosis following implant placement.
