Loss of attachment will be equal to pocket depth when
1. Gigival margin is at cementoenamel junction
2. Gigival margin is 2 mm coronal to CEJ
3. Gigival margin is 2 mm apical to CEJ
4. Epethelial attachment is at CEJ but depth of pocket is increased
Pedodontics
Answer: 1
Loss of attachment will be equal to pocket depth when the gingival margin is at the cementoenamel junction.
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.

1. Parcussion of tooth
2. Digital palpation
3. Shimmock paper
4. Bite marking paper

Clinical changes that may be apparent after scaling and root planning
1. Gain in attachment and reduction of pocket depth
2. Reduction in inflammation and pocket depth
3. Both A and B
4. None of A and B
Pedodontics
Answer: 2
Reduction in inflammation and pocket depth is a clinical change that may be apparent after scaling and root planing.
