1. Which type of collagen fibers demonstrates “chicken wire” configuration Type II Type III Type I Type IV 2. Nerve fibers in dental pulp are Motor fibers Parasympathetic postganglionic Both autonomic parasympathetic and motor fibers Sympathetic and afferent post ganglionic 3. The parotid duct opens on the oral surface of the cheek through a small opening opposite which tooth listed below? Maxillary first premolar Mandibular first molar Maxillary second molar Mandibular second molar 4. Which of the following intrinsic muscle fibers flattens and broadens the tongue Horizontal Transverse Vertical Longitudinal 5. The glenoid fossa is a portion of which bone? Temporal Zygomatic Maxilla Mandible 6. Sex determination is possible with which of the following protein Amelogenin osteopontin Dentin sialoprotein Tuftelin 7. The enamel has no capacity of self repair because It is essentially a keratin tissue and has no blood vessels Its formative cells are lost once it is completely formed It has no direct connection with the active cells of the dental pulp It has only a small percent of organic content 8. Which teeth listed below should ideally provide the predominant guidance through the full range of movement in lateral mandibular excursions? First molars Canines Incisors Premolars 9. The contact area between the maxillary central incisors is located at Middle of middle third Incisal third Middle third Junction of incisal and middle third 10. How many planes of movement can the mandible move in? One Four Two Three 11. Sensation of pain in pulp is mediated by Large myelinated fibers Large unmyelinated fibers Small unmyelinated fibers None of the above 12. A particular glycoprotein which occurs in filamentous form in the periodontal ligament is called Fibronectin Hydroxyproline Chitin Proline 13. Th cap stage contains the following transitory structures Enamel knot,enamel cord and enamel niche Stratum intermedium Enamel matrix Cervical loop 14. Color of primary teeth is lighter than permanent teeth because of Contrast with the adjacent,there is difference in light reflection Difference in the color of enamel Dentin underlying the enamel is thin Difference in crystalline structure therefor there is difference in refractive index of enamel 15. A bacterial enzyme capable of altering the ground substance of the PDL is Mucinase Hyaluronidase Dextrase Amylase 16. Which of the following chronic conditions may cause tooth abrasion? Pipe smoking Nocturnal bruxism Occlusal trauma GERD 17. The most widely accepted theory for dentinal hypersensitivity is none of the above hydrodynamic direct neural stimulation transduction 18. Which teeth listed below typically have trifurcations? Maxillary molars Mandibular premolars Mandibular molars Maxillary premolars 19.
