A large breed dog presented for a periodontal cleaning. During a periodontal examination how many surfaces of the tooth should be evaluated with a periodontal probe?

Answer:

Minimally 6 surfaces should be probed (mesial-buccal, buccal, distal-buccal, distal-lingual, lingual, mesial-lingual) by walking, not dragging, the periodontal probe around the tooth.

Question:

During the periodontal examination a 12 mm+ distal-lingual periodontal pocket is identified. What is the next diagnostic step?

Answer:

Intraoral Radiography

Question:

What is the radiographic interpretation and diagnosis?

Answer:

There is widening of the distal periodontal ligament space of tooth the right mandibular first molar (tooth 409) associated with vertical bone loss estimated to be approximately 75% (stage 4 periodontal disease). Vertical bone loss results in an intrabony periodontal pocket.

Treatment options for tooth 409 include:

  1. Guided tissue regeneration of tooth 409
  2. Hemisection of the distal root of tooth 409 with root canal treatment of the mesial root.
  3. Surgical Extraction.
