1. An enzyme present in saliva which causes cell wall lysis Peroxidase Lactoferrin Hyaluronidase Lysozyme 2. Odland bodies are seen in Stratum spinosum Stratum corneum Both A and B Stratum granulosum 3. Which of these is not a type of occlusal morphology of mandibular 2nd premolar V Y H U 4. enamel spindle is thin leaf like faults between enamel rods extending from enamel surface to DEJ surface projection of Striae of Retzius hypomineralised structures of enamel rods projecting between adjacent groups of enamel rods from DEJ Odontoblastic processes that cross the DEJ into the enamel 5. Wandering cells of pulp are Histiocytes Lymphoid wandering cells Fibroblasts Undifferentiated mesenchymal cells 6. Tuft cells function as receptor cell in Excretory ducts of salivary glands Synovial membrane of TMJ Cell rich zone Maxillary sinus lining 7. All of the following muscles are infrahyoid muscles, except the: Mylohyoid muscle Sternohyoid muscle Omohyoid muscle Thyrohyoid muscle 8. The only tooth with three different occlusal schemes is the mandibular 1st premolar. mandibular 1st molar. mandibular 2nd molar mandibular 2nd premolar. 9. Saliva which is formed in salivary gland when passes from salivary acini to duct orifices, it undergoes ion exchanges and as a result, saliva becomes Hypertonic isotonic all of the above hypotonic 10. Enamel of primary and permanent teeth differ in Enamel is same in primary and permanent teeth,only the dentin is different Enamel prism arrangement None of the above Mineral content 11. Which anterior tooth has the greatest faciolingual-to-mesiodistal length ratio when viewed from the occlusal? Mandibular central incisor Mandibular lateral incisor Maxillary central incisor Maxillary lateral incisor 12. Which cusp on permanent molars generally is the one that gets progressively smaller as you go posterior in the arch? Distolingual Mesiobuccal Distobuccal Mesiolingual 13. The distal contact area of a permanent mandibular canine is usually located where? lncisal third Middle third Junction of the incisal and middle third None of the above 14. Compact bone and cellular cementum are similar as they contain Collagen fibers and blood vessels Lacunae and elastic fibers Sharpey’s fibers and elastic fibers Canaliculi and incremental lines 15. Primary saliva is isotonic. It is modified to become hypotonic while coming into oral cavity in Canaliculi Intercalated ducts major secretory ducts Striated ducts 16. In which of the following areas is the alveolar process the thinnest Lingual to maxillary CI Lingual to the maxillary canine Buccal to mandibular CI Lingual to the mandibular first molars 17. Tomes process is a derivative of Mesenchymal cell Ameloblast Odontoblast Amelocyte 18. When distinguishing a mandibular canine from a maxillary canine, all of the following are true, except: On a mandibular canine, the mesial border is much straighter (viewed facially) The mandibular canine has a comparatively wider mesiodistal dimension (viewed facially) The cusp tip is displaced lingually on the mandibular canine, whereas on the maxillary canine the cusp is on or labial to the root axis line (viewed proximally and incisally) The mandibular canine has a cingulum that is less pronounced and often slightly to the distal, whereas the maxillary canine has a cingulum that is more pronounced and centered mesiodistally (viewed lingually) 19. The mesial and distal aspect (or surfaces) of all anterior teeth have a: Trapezoidal outline Triangular outline Square outline Rhomboidal outline 20. The parotid duct opens on the oral surface of the cheek through a small opening opposite which tooth listed below? Maxillary second molar Mandibular first molar Maxillary first premolar Mandibular second molar Loading … Question 1 of 20
