1. Moyers D type CLASS II malocclusion is Orthognathic Maxilla / Retrognathic Mandible Orthognathic Maxilla / Orthognathic Mandible Prognathic Maxilla / Retrognathic Mandible Retrognathic Maxilla / Retrognathic Mandible 2. Two millimeters of maxillary incisor spacing in a 3 year old is indicative of a tooth size-arch size discrepancy. persistent tongue thrusting. maxillary Bolton deficiency. normal pattern of development. 3. In a mouth breather, tonicity of upper lip is Decreased No change Increased Slightly affected 4. What is the right sequence of orthodontic treatment planning from diagnosis to result: Treatment objectives, treatment planning, Synthesis and diagnosis, plan mechanics, treatment Synthesis and diagnosis, treatment planning, treatment objectives, plan mechanics, treatment Synthesis and diagnosis, treatment objectives, treatment planning, plan mechanics, treatment Synthesis and diagnosis, plan mechanics, treatment objectives, treatment planning, treatmen 5. For bite opening in orthodontics, which of the following is done: Retraction of anterior teeth Intrusion of anterior and extrusion of posterior teeth Mesialization of posterior teeth Extrusion of anterior and intrusion of posterior teeth 6. In a tooth with alveolar bone resorption what will be the change in center of resistance? It will shift coronally No change It will move outside the tooth It will shift apically 7. 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: Extracting the primary second molar Use of a brass wire to move the permanent molar distally Removing the soft tissue overlying the occlusal surface of permanent molar Disking of the distal surface of the primary second molar 8. Teeth with root fracture cannot be moved orthodontically for: 3 months 1 year 1 month 6 months 9. Inability to produce bilabial sounds properly like /b/ and /p/ along with lisp like sounds is seen in which malocclusion: Class I type 4 Class I type 3 Class II division 1 with incompetent lips Class III with competent lips 10. For planning treatment in a patient with facial asymmetry requiring orthognathic surgery, which of the following is required: Model analysis CBCT Grummons analysis OPG 11. 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 only if it develops into a cystic lesion after its complete eruption. as soon as possible. once the patient has reached the age of 12. 12. Labiodental sounds are affected in: Class I type 1 malocclusion Class IT malocclusion Class I type 2 malocclusion Class III malocclusion 13. If the centre of rotation is at the apex of the root, then the orthodontic movement which results is: Uncontrolled tipping Torquing Controlled tipping Translation 14. The most appropriate time for surgical treatment of a patient with mandibular prognathism is just before eruption of the second permanent molars. just after eruption of the second permanent molars. following the completion of growth. just after the end of the prepubertal growth spurt. 15. Overbite is defined as: The horizontal overlap of mandibular over maxillary anterior teeth The vertical overlap of maxillary anterior over mandibular anterior teeth The horizontal overlap of the maxillary and mandibular anterior teeth Distobuccal cusp of maxillary 1st molar occludes with the central fossa of mandibular 1st molar 16. All of the following are a feature of Complex Tongue Thrust except? Contraction of the circumoral muscles during swallowing. The occlusion of teeth may be poor. This tongue thrust is characterized by teeth together swallow. The anterior open bite can be diffused or absent. 17. Generalized Anterior crossbite in the primary dentition indicates: A dental malrelation A developing Class III malocclusion A developing Class II malocclusion A normal maxillo-mandibular relation 18. Which type of malocclusion should be corrected as early as possible? Anterior open bite associated with a lip or digit sucking habit. Class II Division 2 associated with an increased anterior overbite. Cross-bite associated with a functional shift of the mandible from initial contact to maximum intercuspation. Class II Division 1 associated with an anterior open bite. 19. In Downs analysis, an increase in Y axis is suggestive of: Average growth pattern Horizontal growth pattern Vertical growth pattern Skeletal dysplasia 20.
