1. The bell stage of tooth development refers to Proliferation Dental lamina Apposition of dental tissues Histodifferentiation and morphodifferentiation 2. Which papillae are completely keratinised Filiform Circumvallate Foliate Fungiform 3. The character of occlusal contacts in the unworn dental arch are all of the following, except: Edge-to-edge Point-to-point Point-to-area Area-to-area 4. The enamel has no capacity of self repair because It is essentially a keratin tissue and has no blood vessels It has only a small percent of organic content Its formative cells are lost once it is completely formed It has no direct connection with the active cells of the dental pulp 5. Congenital absence of tooth is due to aberration in Initiation Histodifferentiation Apposition Morphodifferentiation 6. An enzyme present in saliva which causes cell wall lysis Hyaluronidase Peroxidase Lysozyme Lactoferrin 7. The prime mover in effecting a left working-side movement is: The left medial pterygoid muscle The left lateral pterygoid muscle The right lateral pterygoid muscle The right medial pterygoid muscle 8. Which of the following premolars does not develop from four lobes Maxilary 1st premolar Maxillary 2nd premolar Mandibular 1st premolar Mandibular 2nd premolar 9. Leeway space is due to space differential between deciduous canine and molar and their succadaneous permanent teeth difference between deciduous and permanent maxillary canines space differential between deciduous incisors and their succedaneous permanent teeth none 10. To identify bite mark in case of child abuse bite mark of the offender should be recorded with Silicone putty Polyvinyl siloxane Alginate Impression plaster 11. according to recent research, following is true about of pattern of enamel prism demineraliation head is more resistant to dissolution than tail both head and tails are equally susceptible to dissolution tail is more resistant to dissolution than head both head and tails are equally resistant to dissolution 12. Amelogenesis imperfecta is due to PAX9 ENAM DSPP MSX-1 13. According to Brealey and Mckibbon(1973)commonly ankylosed teeth in deciduous dentition are maxillary canine maxillary incisor mandibular molar mandibular canine 14. High level of amino peptidase is seen in Ameloblasts Stellate reticulum Dental lamina Stratum intermedium 15. During cap stage signaling in odontogenic epithelium is done by Enamel knot Inner enamel epithelium Dental follicle Dental papilla 16. The commonest teeth involved in transposition are Maxillary canine and 1st PM Maxillary CI and LI Maxillary canine and LI Maxillary 1st PM and 2nd PM 17. In non functioning teeth there is None of the above Thickening of cementum Thinning of cementum No change in cementum 18. The ligament attached to lingula is Sphenomandibular None of the above Stylomandibular Temporomandibular 19. Which tooth listed below is the smallest and the narrowest (mesial to distal) of all permanent teeth? Maxillary central incisor Mandibular lateral incisor Mandibular central incisor Maxillary lateral” incisor 20. 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 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) 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) Loading … Question 1 of 20
