Periodontics
Answer: 3
Occlusal guard (night guard0 or maxillary splint is given in bruxism to
1) Prevent bruxism
2) Reduce pocket formation
3) Reduce traumatic forces on teeth
4) Prevent elongaton of teeth
Periodontics
Answer: 3
What is the significance of the load deflection rate in orthodontic wires?
1) Low load deflection wires are preferred for large tooth movements.
2) High load deflection wires are preferred for large tooth movements.
3) The load deflection rate does not affect wire selection.
4) The load deflection rate determines the force applied during wire bending.
In orthodontics, wires with a low load deflection rate are typically preferred for areas requiring large tooth movements because they provide a more constant force as the tooth moves and the appliance is deactivated. This constant force is beneficial for controlling the rate of tooth movement.
For the preparation of the rest seat in the marginal ridge of a molar tooth which is reduced by 2 mm to achieve the correct width of the rest seat. The marginal ridge is then rounded in order to
1) Reduce the chances the fracture of the metal rest
2) Decrease food impaction
3) For better distribution of the vertical load
4) Better clasp retention
Prosthodontics
Answer: 1
Gemination of teeth occurs due to
1. Division of a single tooth bud after calcification
2. Division of a single tooth bud before calcification
3. Fusion of two teeth before calcification
4. Fusion of two teeth after calcification
Oral Pathology
Answer: 2
The anatomical radiolucent area in maxillary posterior periapical area may be confused as pathological condition is
1. Maxillary sinus
2. Coronoid process
3. Infraorbital foramen
4. Sphenoid sinus
Radiology
Answer: 1
Occlusal trauma may be best defined as a condition caused due to
1) The pressure on teeth due to lack of proper arch alignment
2) Failure of occlusal balance bilaterally
3) The force or the pressure beyond the physiological limits to the periodontium
4) None of the above
Periodontics
Answer: 3
What is the role of the vagus nerve in the parasympathetic system?
1) Control of heart rate and gastric motility
2) Control of pupil dilation and salivation
3) Control of skeletal muscle contraction
4) Control of pituitary hormone secretion
The vagus nerve, as part of the parasympathetic system, innervates various organs in the thoracic and abdominal cavities, influencing heart rate and gastric motility among other functions.
