1. Compared to homogenous populations, malocclusion in a heterogenous population is: Same Cannot be said Lower Higher 2. Primate space in mandibular arch is present between: Canine and premolar 1′ and 2″ primary molars Lateral incisor and canine Canine and primary first molar 3. Which orthodontic analysis uses the dimensions of the upper and lower anterior teeth to predict the dimensions of the posterior teeth: Hixon and Oldfather Moyers analysis Bolton’s analysis Carey’s analysis 4. There is a difference between girls and boys with respect to the age at which the growth velocity reaches its peak. Boys are six months ahead of girls. Girls are one year ahead of boys. Girls are six months ahead of boys. Girls are two years ahead of boys 5. Transverse cant of occlusal plane is seen in frontal plane examination. It occurs due to: Alteration in pitch of dentition Alteration in roll of dentition Change in yaw of dentition Alteration and abstraction of jaw 6. Prior to the correction of a one tooth anterior crossbite, the principle factor to consider is the morphology of the anterior teeth. adequacy of mesio-distal space. sequence of eruption of the permanent dentition. developmental age of the patient. 7. The permanent maxillary canine most commonly erupts before the maxillary first premolar. before the maxillary second permanent molar. after the maxillary second permanent molar. before the mandibular permanent canine. 8. Xi point is seen in which of the following analysis: Sassouni analysis Down Ricketts Steiner 9. The most significant factor in determining the prognosis of anterior crossbite correction is the shape of the tooth involved. space available mesiodistally. depth of the overbite. age of patient. 10. 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: Not related to duration 6 hrs daily 4 hrs daily 2 hrs daily 11. Which of these is most promising soft tissue investigation: Tc scan Stereophotogrammetry Barium Meal Poor man cephalometry 12. According to the NORMS of the orthodontic study models, the total height of maxillary n mandibular model should be close to? 70 mm 90 mm 55 mm 60 mm 13. How much overjet can be successfully managed using dentofacial orthopedics: 0-7 mm 5-7 mm 10-14 mm 14-18 mm 14. During active tooth movement, hyalinization is seen during: Lag phase Post-lag phase All three stages Initial phase 15. Orthodontic tooth movement in a patient with concussion, subluxation extrusion and simple crown/root fracture should be postponed by: 15 days 1 year 6 months 3 months 16. Tanaka Johnson analysis uses width of which teeth to estimate the width of maxillary canine and premolars: Maxillary molars Maxillary incisors Mandibular molars Mandibular incisors 17.
