3. Flattening interproximal bone
4. Gradualising marginal bone
Periodontics
Answer: 1
The first sequential step in the osseous resection technique is vertical grooving.
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.
The treatment of choice for generalized fibrous gingival hyperplasia is
1. lateral pedicle flap
2. full thickness flap surgery
3. gingivectomy
4. root planning and curettage
Periodontics
Answer: 3
Fibrous gingival hyperplasia, also known as gingival overgrowth, is
characterized by an increase in the size of the gingival tissue due to an
excessive accumulation of collagen and other extracellular matrix components.
This condition can be caused by various factors, including certain medications
(like anticonvulsants, calcium channel blockers, and immunosuppressants),
hormonal changes, or chronic inflammation.
Which of the following radiographic changes are associated with gingivitis?
1. Increased width of the periodontal ligament space
2. Widening of medullary spaces and loss of trabeculation
3. Irregularity of the crestal lamina dura
4. None of the above
Periodontics
Answer: 4
Typically, gingivitis does not present distinct radiographic changes as seen in
periodontitis, where bone loss is evident. Gingivitis is characterized mainly by
inflammation of the soft tissues.
The relationship between the working edge of the instrument and the tooth surface is
1. Angulation
2. Access
3. Adaptation
4. Activation
Periodontics
Answer: 3
The relationship between the working edge of the instrument and the tooth surface is called adaptation.
The following tooth has poorest prognosis after furcation therapy due to limited instrument accessibility
1. Maxillary first molar
2. Maxillary Second molar
3. Mandibular first molar
4. Maxillary first premolar
Periodontics
Answer: 4
The tooth with the poorest prognosis after furcation therapy due to limited instrument accessibility is the maxillary first premolar.
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.
The main objective of maintenance therapy is
1) To initiate secondary surgical procedures
2) To identify aetiological agent
3) To prevent recurrence of disease
4) None of the above
Periodontics
Answer: 3
Maintenance therapy is designed to support the long-term health of periodontal
tissues after initial treatment. By regularly monitoring and managing
periodontal disease, practitioners can help prevent disease recurrence and
maintain periodontal health.
