All of the above

6. Primary teeth are lighter than permanent teeth because

Because of contrast with the adjacent tissue

Difference in crystalline structure makes refractive index different

Lighter color of enamel

Thin dentin in primary teeth

7. Which treatment is the proper one for a class ll fracture of a permanent tooth with an immature apex?

Pulpotomy

Pulpectomy

Apply calcium hydroxide to exposed dentin and restore tooth with a permanent restoration

Observe

11. Mother of a child is worried about green stains on the recently erupted upper anterior teeth of her child. The stains are most probably due to:

Calculus

Material alba

Chromogenic bacteria

Neonatal line

12. The presence of higher amounts of proline rich proteins (PRP) can have what kind of effect on caries causation

Make tooth surface resistant to caries since it enhances fluoride action

It has role during tooth remineralisation only therefore no effect on caries

Aid in super saturation of saliva therefore make tooth resistant to caries

Caries promoting since they help in bacterial adherence

13. Most common caries seen in primary 1 molar:

Occlusal pits and fissures

Proximal surface above contact point

Proximal surface below contact point

Buccal surface below height of contour

14. A lady with an Infant reported to clinic with the complaint of white teeth like structure, at the level of gingiva in mandibular anterior region. What should dentist do?

Extract the structure under GA

Selective grinding & let it remain

Reassure the parents as root will develop later

Extract it under la

5 sec

5 min

10 sec

10 min

16. In the primary dentition, the mandibular foramen is located where in relation to the plane of occlusion?

Higher than the plane of occlusion

Lower than the plane of occlusion

The same level as the plane of occlusion

Much higher than the plane of occlusion

17. Your patient is 8 years old. Teeth #8 and #9 have approximately 50% of their crowns erupted. One month ago, the patient fell from a skateboard and hit teeth #8 and #9 on the sidewalk. The radiograph today shows open apices of these teeth, normal PDL, and no apparent periapical radiolucency. The patient has no reaction to electrical pulp tests. What is your treatment of choice?

Calcium hydroxide apexification technique

Reappoint for exam and radiographs in 6 weeks

Formocresol apexification technique

Calcium hydroxide pulpotomy

18. At birth child shows marked convex profile. This is due to

Small sized mandible

Protruted maxilla

Retruded mandible

Large size maxilla

Surface necrosis

Moderate inflammatory response

Mild inflammatory response

Severe inflammatory response
