1. An Angle Class II, division 1 malocclusion can be differentiated from an Angle Class II, division 2 malocclusion based upon the amount of overbite. severity of the Angle Class II malocclusion. inclination of maxillary incisors. molar relationship. 2. 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 two years ahead of boys Girls are six months ahead of boys. Girls are one year ahead of boys. 3. Which of the following soft tissues of the oro facial region mature first: Posterior 1/3rd of tongue All soft tissues mature simultaneously Tip of tongue Lips 4. An 8 year old patient with all primary molars still present exhibits a cusp-to-cusp relationship of permanent maxillary and mandibular first molars and good alignment of the lower incisors. The management of this patient should be to place patient on appropriate recall schedule. disk the distal surfaces of primary mandibular second molars. use a cervical headgear to reposition maxillary molars. refer for orthodontic consultation. 5. Premature loss of a primary maxillary second molar usually produces a malocclusion in the permanent dentition that is characterized by an Angle Class II molar relationship on the affected side. labially displaced maxillary canines. delayed eruption of the permanent first molar. an Angle Class III molar relationship on the affected side. 6. The body of the mandible increases in length to accommodate the permanent second molar by apposition of bone on the alveolar margin and lower border of the body of the mandible. resorption of bone along the anterior border of the ramus and apposition of bone on the posterior border of the ramus. apposition of bone in the condyle. apposition of bone at the symphysis and posterior border of the ramus of the mandible. 7. If the centre of rotation is at the apex of the root, then the orthodontic movement which results is: Controlled tipping Torquing Uncontrolled tipping Translation 8. Alveolar bone is undergoing remodelling through the primary dentition. until the complete eruption of permanent teeth. until the end of mixed dentition. throughout life. 9. Incisal liability in the maxillary and mandibular arch is: 6 mm maxilla, 4 mm mandible 7 mm maxilla, 5 mm mandible 4 mm maxilla, 6 mm mandible 5 mm maxilla, 7 mm mandible 10. In long face individuals, who have excessive lower anterior facial height, the palatal plane is rotated Down anteriorly Up posteriorly Down posteriorly No rotation of the palatal plane 11. Phsio-Print’ is a term given to A test to assess mental growth and correlate to the dental growth Physiologic assessment of growth changes Facial mask of patient taken before and after treatment A photographic orientation technithat permits measurement of facial contours and volume 12. The cranial vault is made up of a number of flat bones that are formed by _________________ , ________ cartilaginous precursors. Both endochondral and intramembranous bone formation; with Intramembranous bone formation; without Endochondral bone formation; with Both endochondral and intramembranous bone formation; without 13. Bien theory is related to: Osteitis Bone regeneration Tooth movement Osteomyelitis 14. Areas of isolated gingival recession are most frequently seen on teeth that are ankylosed. nonvital. labially prominent in the arch. moderately mobile. 15. The mechanism of adjustment to maintain the shape and proportions of bone throughout its growth period is called remodeling. translatory growth. cortical drift. area relocation. 16. Overbite is defined as: Distobuccal cusp of maxillary 1st molar occludes with the central fossa of mandibular 1st molar The horizontal overlap of the maxillary and mandibular anterior teeth The vertical overlap of maxillary anterior over mandibular anterior teeth The horizontal overlap of mandibular over maxillary anterior teeth 17. Progressive malocclusion is: Class I Class II Class III A+C 18. Maxillary arch increases in length by: Deposition of bone at Tuberosity Development of alveolar process Growth at the sphenozygomatic suture Development of Palate 19. All of the following are a feature of Complex Tongue Thrust except? Contraction of the circumoral muscles during swallowing. The anterior open bite can be diffused or absent. This tongue thrust is characterized by teeth together swallow. The occlusion of teeth may be poor. 20. Appearance of ulnar sesamoid bones in hand occurs: Birth At the end of pubertal spurt At onset of pubertal growth spurt At the prepubertal spurt Loading … Question 1 of 20
