Answer: 4
Pyogenic granuloma bleeds on touch, is painless, and is soft in consistency.
Transgingival probing is performed
1. To know the bone architecture after the area is anaesthetised
2. To know the level of attachment
3. To determine the disease activity
4. To know the functional occlusal relationships
Periodontics
Answer: 1
Transgingival probing is performed to know the bone architecture after the area is anesthetized.
Following is a contraindication to resection of crestal bone
1. Gingival recession
2. Postsurgical infection
3. Weakening of support to adjacent tooth
4. All of the above
Periodontics
Answer: 3
Weakening of support to adjacent teeth is a contraindication to resection of crestal bone.
Radiographs alone can be used to accurately determine the
1. presence of calculus
2. anatomic root length
3. presence of an apical abscess
4. severity of gingivitis
Periodontics
Answer: 2
Radiographs allow clinicians to see the anatomical structure of the root;
however, they often cannot accurately assess conditions like the presence of
calculus or severity of gingivitis.
Craters in facial and lingual interdental bone are best eliminated by
1) Gingivectomy
2) Osseous reconturing
3) Osseous regeneration procedure
4) Curettage
Periodontics
Answer: 3
Craters in the facial and lingual interdental bone are typically associated with periodontal disease and result from the loss of bone due to inflammation and infection. Osseous regeneration procedures, such as guided bone regeneration (GBR) or the use of bone grafts, are specifically designed to restore lost bone structure. These procedures promote the growth of new bone in the affected areas, effectively filling in the craters and restoring the contour of the alveolar ridge. Gingivectomy and curettage are more focused on soft tissue management and do not address the underlying bone loss, while osseous recontouring may not be as effective in restoring lost bone volume.

1. Glickmann
2. Listgarten
3. Lindhe
4. Wearlug
Periodontics
Answer: 2
Bacterial invasion of connective tissue in ANUG was demonstrated by Listgarten.
The main blood supply to the buccal marginal gingiva is from the
1. subperiosteal vessels
2. interdental alveolar blood vessels
3. main artery of the pulp
4. supraperiosteal vessels
Periodontics
Answer: 4
The buccal marginal gingiva receives its main blood supply from the supraperiosteal vessels, which are located above the periosteum (a layer of connective tissue that covers the bone). These vessels are part of the periodontal ligament's blood supply and provide nutrients to the superficial tissues of the gum
