The most important objective in equilibrating the natural dentition is to
1. ensure balance in eccentric movements
2. narrow the occlusal table
3. achieve a more favorable distribution of occiusal forces
4. eliminate open contacts and prevent food impaction
Periodontics
Answer: 3
Equilibration aims to distribute occlusal forces evenly across the dentition to
prevent excessive stress on individual teeth, thereby reducing the risk of
mobility, wear, and periodontal issues.
Pigmentation of chemicals in mucosa is due to
1. Increased permeability of blood vessels
2. Local deposition of chemicals in muscosa
3. Subepithelial precipitation in connective tissue at the site due to increased capillary permeability
4. None of the above
Periodontics
Answer: 4
Pigmentation of chemicals in the mucosa is due to local deposition of chemicals in the mucosa.
The bacteria found in gingivitis are located in the
1. alveolar bone
2. periodontal pocket
3. periodontal ligament
4 connective tissue of the marginal gingiva
Periodontics
Answer: 4
In gingivitis, bacteria primarily reside in the connective tissue of the
marginal gingiva and within the plaque biofilm on the tooth surface. This
location contributes to the inflammatory response seen in gingivitis.
When should the correction of occlusal prematurities be performed?
1 At the same time as soft tissue surgery
2 Before starting soft tissue therapy
3. Gross corrections should be done be- fore surgery and finer adjustments after surgery
4. After tissue healing, following surgery is completed
Periodontics
Answer: 3
Addressing significant occlusal prematurities prior to surgical intervention
prevents undue stress and facilitates proper healing, while finer adjustments
can be made post-surgically.1
Which of the following groups of fibers belongs to the gingivodental group and not to the periodontal ligament?
1. Circular
2. Alveolar crest
3. Transseptal
4. Horizontal
Periodontics
Answer: 1
The circular fibers are part of the gingivodental group and are located in the
marginal gingiva, encircling the teeth. In contrast, the alveolar crest,
transseptal, and horizontal fibers are part of the periodontal ligament.
Which one of the following holds good i case of iontophoresis
1) Sodium chloride is used in this technique
2) It is safe to use on people with pacemakers
3) The pulp tester is used for the electric charge
4) It encourages negative ions to penetrate the tooth ions
Periodontics
Answer: 4
Explanation: Iontophoresis is a technique that uses a small electric current to drive charged substances (ions) into tissues. In dentistry, it is often used to deliver fluoride ions into the tooth structure, and it specifically encourages negative ions to penetrate.
In the conventional finger rest, the finger rest is established on the
1. Other side of the same teeth
2. Tooth surface immediately adjacent to the working area
3. Opposing arch
4. None of the above
Periodontics
Answer: 2
In the conventional finger rest, the finger rest is established on the tooth surface immediately adjacent to the working area.
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.
