1. The type of bone present in the labial area of anterior teeth is Cortical Exophytic Osteophytic Cancellous 2. According to Brealey and Mckibbon(1973)commonly ankylosed teeth in deciduous dentition are mandibular molar mandibular canine maxillary canine maxillary incisor 3. The only tooth wider lingually than buccally is Maxillary 1st molar Mandi 1st molar Maillary second premolar Maxillary 2nd molar 4. Th cap stage contains the following transitory structures Cervical loop Enamel matrix Stratum intermedium Enamel knot,enamel cord and enamel niche 5. Atypical dentin is formed due to defect in Morphodifferentiation Apposition Initiation Histodifferentiation 6. High level of amino peptidase is seen in Stellate reticulum Stratum intermedium Dental lamina Ameloblasts 7. All of the following teeth are nonsuccedaneous, except: The permanent maxillary and mandibular second molars The permanent maxillary and mandibular premolars The permanent maxillary and mandibular first molars The permanent maxillary and mandibular third molars 8. Which of the following represents the most common anatomic feature that complicates periodontal maintenance in a maxillary first premolar Excessive convexity of the faical root Intermediate furcational ridge Mesiolingual developmental groove Deep concavity on the mesial surface of the tooth 9. In which of the following areas is the alveolar process the thinnest Lingual to the maxillary canine Buccal to mandibular CI Lingual to maxillary CI Lingual to the mandibular first molars 10. In which of the following mandibular positions would you find the greatest increase in VDO from centric occlusion? Maximum protrusion Postural position Anterior edge-to-edge position Centric relation 11. The peripheral axons from a network of nerves located adjacent to the cell rich zone in pulp is known as 5HT Zone of weil Brachial plexus Plexus of rashkow 12. Which of the following is the smallest primary molar? Mandibular 1st Maxillary 1st Mandibular 2nd Maxillary 2nd 13. Supporting cells of taste buds are called as Acini Von ebner cells Sustenticular cells Taste cells 14. Color of primary teeth is lighter than permanent teeth because of Contrast with the adjacent,there is difference in light reflection Difference in crystalline structure therefor there is difference in refractive index of enamel Difference in the color of enamel Dentin underlying the enamel is thin 15. Ca10PO4(OH)2 is Hydroxyapatite Silicate Whitlockite Magnetite 16. Congenital absence of tooth is due to aberration in Histodifferentiation Morphodifferentiation Apposition Initiation 17. true regarding epithelial lining of tongue is non stratified non keratinised squamous epithelium stratified squamous non keratinised epithelium stratified squamous keratinised, specialized stratified squamous,non keratinised, specialised 18. Before eruption the position of permanent mandibular incisor buds relative to primary incisors is inferior and facial superior and facial inferior and lingual superior and lingual 19. As the osteoclasts move through bone, the leading edge of resorption is known as Cutting cone Cement line Reversal line Filling cone 20. Ameloblast are derived from Surface ectoderm Neural crest cells Endoderm Mesoderm Loading … Question 1 of 20
