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.
Which of the following roots are most likely to have flutings in their mesial surfaces which will make thorough root planning difficult?
1. Maxillary central incisor
2. Mandibular second premolar
3. Maxillary first premolar
4. Mandibular canine
Periodontics Answer: 3
The maxillary first premolar often has developmental grooves and flutings on the
mesial surface that can complicate thorough root planing and make it more
challenging to fully debride the root surface.
For interproximal areas of disastemata or for wide interdental spaces to properly adopt the interproximal papilla against the bone, the recommended technique to suturing method is
1. Interdental ligation
2. Horizontal mattress suture
3. Continuous, independent sling suture
4. Closed anchor suture
Periodontics
Answer: 2
The recommended suturing method for interproximal areas of diastemata is horizontal mattress suture.
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.
Pyogenic granuloma
1. Bleeds on touch
2. Painless
3. Soft in consistency
4. All of the above
Periodontics
Answer: 4
Pyogenic granuloma bleeds on touch, is painless, and is soft in consistency.
The outcome of results of laterally positioned flap depends on
1) Presence of sufficient bone support at donor site
2) Thickness of attached gingiva at donor site
3) Width of attached gingiva at donor site
4) All of the above
Periodontics
Answer: 4
Explanation:The success of a laterally positioned flap in periodontal surgery is influenced by several factors, including the presence of sufficient bone support at the donor site, the thickness of attached gingiva at the donor site, and the width of attached gingiva at the donor site. All these factors contribute to the healing and stability of the flap.
The purpose of guided tissue regeneration is
1. Prevention of epithelial migration
2. Elimination of junctional and pocket epithelium
3. Complete removal of all irritants
4. Careful curettage of the pocket wall surface
Periodontics
Answer: 1
The purpose of guided tissue regeneration is to prevent epithelial migration.
Sensitivity of roots after periodontal surgery results from all of the following except
1) Exposed dentine tubules
2) Exposed cementum
3) Formation of plaque
4) None of the above
Periodontics
Answer: 2
After periodontal surgery, root sensitivity is primarily due to the exposure of dentin tubules (option 1). When the root surface is exposed, the dentin becomes sensitive to stimuli because the tubules can transmit sensations to the pulp.
Exposed cementum (option 2) is less likely to cause sensitivity because cementum is not as innervated as dentin. Formation of plaque (option 3) can lead to sensitivity as it may irritate the surrounding tissues and contribute to inflammation.
