An Ellis Class IV crown fracture
1. does not involve the pulp
2. is so extensive that the entire crown has been lost
3. involves only the enamel
4. may expose the pulp
Pedodontics
Answer: 2
An Ellis Class IV crown fracture is characterized by the loss of a significant portion of the crown, often such that the pulp may be exposed. This severe type of fracture requires immediate attention to prevent further damage to the tooth
Ellis Class IV fractures are the most severe form of crown fractures. They extend below the gingival margin and involve the enamel, dentin, and often the pulp. The pulp may be exposed, making it a dental emergency.

2. Oedema in the tissue
3. Nature of bone loss
4. Type of instrument

The principal advantage of functional type of space maintainer is
1) It is removable
2) Replaces the tooth/teeth
3) Prevents mescal drift of the permanent molar
4) Prevents supraeruption of the teeth of the opposing arch
Pedodontics
Answer: 4
Functional space maintainers are typically made to be removable for ease of cleaning and adjustment, which is essential for the patient's oral hygiene and the overall success of the treatment. While they also replace the tooth/teeth and prevent mesial drift and supraeruption of teeth from the opposing arch, the key advantage is their ability to maintain function and promote proper eruption of the permanent teeth.

1. Curve of Manson
2. Curve of Wilson
3. Curve of Spee
4. Pleasure curve
Pedodontics
Answer: 4
The occlusal line produced due to reversal of cuspal inclines in bruxism patients is called the pleasure curve.
Classification of bony defects most helpful in determining the likelihood of repair after periodontal treatment is based on (or) Angular bone defects are classified based on
1. Depth of bone defect
2. Number of bone walls remaining
3. Distance between the facial, ingual walls
4. None of the above
Pedodontics
Answer: 2
Angular bone defects are classified based on the number of bone walls remaining.
While using a periodontal probe to measure the depth of the periodontal pocket the pocket is measured from
1. Free gingival margin to the cementoenamel junction
2. Junctional epithelium to the free gingival margin
3. Base of pocket to the cementoenamel junction
4. Base of pocket to mucogingival junction
Pedodontics
Answer: 2
While using a periodontal probe, the pocket is measured from the junctional epithelium to the free gingival margin.
