1. Thumb sucking in child leads to change in facial profile (dental and skeletal changes), if the child performs the habit at least for how much time:

2. 12 primary and 12 permanent teeth seen at what age in a child:

3. Seventh key of normal occlusion:

4. Diagnostic aid used for measuring transverse discrepancy and vertical facial dimensions

5. To produce pure translatory motion in a tooth, what type of force is required

6. Moyers D type CLASS II malocclusion is

7. For which of the following malocclusions is serial extraction most appropriate?

8. While treating increased anterior overbite while keeping mandibular plane angle same, increase in molar height is compensated by:

9. In Downs analysis, an increase in Y axis is suggestive of:

10. A patient, when in full intercuspation, shows a right side posterior crossbite and a lower midline that is deviated to the right. At initial contact there are bilateral posterior crossbites and coincident midlines. The most likely cause of this finding is

11. Overbite is defined as:

12. During active tooth movement, hyalinization is seen during:

13. Mesioangular ectopic eruption of a permanent mandibular first molar causing resorption of distal surfaces of the roots of the primary 2nd molar should be treated by:

14. The most common clinical characteristic of a functional crossbite is

16. Maxillary skeletal arch expansion

17. Maxillary 1st molar cusp used in Angle classification

18. A 6 year old patient has a larger than average diastema between the maxillary central incisors. The radiographic examination shows a mesiodens. In order to manage the diastema, you should extract the mesiodens

19. Increased ANB angle signifies:
