A characteristic of gingivitis is
1. vertical bone loss
2. swollen marginal tissue
3. wear of functional cusps
4. apical migration of the epithelial attachment
Periodontics
Answer: 2
Swollen marginal tissue is a hallmark of gingivitis, reflecting inflammation and
edema from plaque accumulation and irritants.
Guided tissue regeneration (GTR) is used mainly in the treatment of
1. Class I furcations
2. Class II furcations
3. Class III furcations
4. All of the above
Periodontics
Answer: 2
Guided tissue regeneration (GTR) is used mainly in the treatment of Class II furcations.
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 facial and lingual interdental bone are best eliminated by osseous regeneration procedures.
A hemiseptum is
1. one-wall defect
2. two-wall defect
3. three-wall defect
4. angular defect
Periodontics
Answer: 1
A hemiseptum refers to a periodontal defect with only one wall remaining, often
seen in sites of periodontal bone loss.
Which of the following represents early effect of primary trauma from occlusion
1) Vertical pockets
2) Generalized alveolar bone loss
3) Undermining resorption
4) Haemorrhage and thrombosis of blood vessels in PD ligament
Periodontics
Answer: 4
The early effects of primary trauma from occlusion can include hemorrhage and thrombosis in the periodontal ligament, leading to inflammation and potential tissue damage.
A young adult shows non-fluctuant, tender and red swelling in the marginal gingival lesion. This is most likely
1. Periodontal abscess
2. Periapical abscess
3. Gingival abscess
4. Periapical sinus
Periodontics
Answer: 3
A young adult with non-fluctuant, tender, and red swelling in the marginal gingival lesion is most likely to have a gingival abscess.
Gore Tex membrane is used during reattachment procedures to
1) Prevent osseous regeneration
2) Prevent connective tissue attachment
3) To prevent formation of long junctional epithelium
4) All of the above
Periodontics
Answer: 3
Gore-Tex is a type of barrier membrane used in guided tissue regeneration (GTR) procedures. Its primary purpose is to prevent the formation of long junctional epithelium, allowing for the regeneration of periodontal tissues, including bone and connective tissue. While it does not directly prevent osseous regeneration or connective tissue attachment, it creates a barrier that favors the regeneration of the desired tissues.
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.
