The term gingival ablation indicates
1) Gingival recession due to faulty tooth brushing
2) Gingival recession accentuated by prominent palatal root
3) Gingival recession due to friction from hard root
4) Gingival recession due to friction from soft tissue
Periodontics
Answer: 4
Gingival ablation is a surgical procedure that involves the removal of a portion of the gingival tissue. It is often used to treat conditions such as excessive gingival overgrowth or to improve the health of the gum tissue. Gingival recession due to friction from soft tissue, such as the tongue or cheek, is one possible outcome of this procedure. It does not inherently involve the removal of tissue due to tooth brushing, prominent roots, or hard tissue friction.
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.
A black line on the gingiva which follows the contour of the margin is due to
1. Lead
2. Argyria
3. Iron
4. Mercury
Periodontics
Answer: 4
A black line on the gingiva which follows the contour of the margin is due to mercury.
Lower first molar has furcation involvement with bifurcation caries, treatment of choice is
1. Endodontic treatment followed by hemisection
2. Hemisection followed by endodontic therapy
3. Apical curettage only
4. None of the above
Periodontics
Answer: 1
The treatment of choice for a lower first molar with furcation involvement and bifurcation caries is endodontic treatment followed by hemisection.
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.
On which of the following tooth surfaces are initial prematurities in retruded contact position most common
1. Distobuccal cusps of maxillary first molars and mesiofacial cusps of mandibular first molars
2. Distal slopes of maxillary canines and mesial slopes of buccal cusps of mandibular first premolars
3. Distal inclines of buccal cusps of mandibular first premolars and mesial in clines of lingual cusps of maxillary first
premolars
4. None of the above
Periodontics
Answer: 3
Distal inclines of buccal cusps of mandibular first premolars and
mesial inclines of lingual cusps of maxillary first premolars
These specific occlusal surfaces are common areas where contacts can develop
prematurely, emphasizing the importance of careful occlusal adjustments.
Osseous form is considered to be ideal when
1. Redicular bone is apical to interdental bone
2. Interdental bone is apical to radicular bone
3. Bone is more coronal in interproximal surface than facial and lingual sides
4. None of the above
Periodontics
Answer: 3
Osseous form is considered ideal when the bone is more coronal in the interproximal surface than the facial and lingual sides.
Vestibular extension procedure results in
1. Increase in width of keratinised attached gingiva
2. Decrease in width of keratinised attached gingiva
3. Increase in width of non-keratinised attached gingiva
4. Decrease in width of non-keratinised attached gingiva
Periodontics
Answer: 3
Vestibular extension procedure results in an increase in width of non-keratinised
attached gingiva
The vestibular extension procedure is a surgical treatment that involves the
apical movement of the vestibular mucosal tissue to increase the width of
attached gingival tissue around a tooth. This procedure typically does not alter
the width of the keratinized attached gingiva, which is the tissue that is
directly connected to the tooth surface. Instead, it primarily increases the
non-keratinized attached gingival width, which is the part of the gingival
tissue that is not directly attached to the tooth but is still important for
periodontal health and aesthetics.
