Reattachment procedures most commonly
1. Reduce pocket depth by formation of long junctional epithelium
2. Reduce pocket depth by reattching periodontal connective tissue fibers
3. Usually heal by secondary intention
4. None of the above

Answer: 1
Reattachment procedures most commonly reduce pocket depth by formation of long junctional epithelium.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
The following most frequently forms at tooth-tissue interface following flap surgery or curettage
1. Scar formation
2. Adhesion of collagen fibres
3. Long junctional epithelium
4. Collagen fibres parallel to root surface
The most frequently formed tissue at the tooth-tissue interface following flap surgery or curettage is long junctional epithelium.
Which of the following flap technique does not eliminate pocket depth and hence cannot increase the width of keratinised gingiva
1) Modified Widman flap
2) Undisplaced flap
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
The Modified Widman flap is designed for access to the root surface for debridement without significantly altering the pocket depth or increasing the width of keratinized gingiva. Other techniques, such as apically displaced flaps, aim to modify the gingival architecture.
Systemic conditions which can affect the health of the gingiva are
1. agranulocytos
2. leukemia
3. granulocytopenia
4. all of the above
Periodontics
Answer: 4
agranulocytosis, leukemia, and granulocytopenia—can significantly impact the
health of the gingiva by affecting the immune response and increasing
susceptibility to infections.
Bone graft procedures are most successful in treating
1) Furcation involvements
2) Deep, two-wall craters
3) Narrow three-wall defects
4) None of the above
Periodontics
Answer: 3
Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.
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
Which of the following is commonly seen in preschool children
1. ANUG
2. Herpetic gingivostomatitis
3. Juvenile periodontitis
4. None of the above
Periodontics
Answer: 2
Herpetic gingivostomatitis is commonly seen in preschool children.
