1. A radiograph of a 4 yr child reveals no evidence of calcification of mandibular second premolars. This means that Primary second molar should be extracted to allow permanent 1st molars to drift forward The child will probably never develop second premolars These teeth may develop later It is too early in life to make final predictions concerning development of any permanent teeth 2. Fluorosis is the result of excessive systemic fluoride during which stage of tooth development? Initiation Calcification Apposition Morphodifferentiation 3. All of the following are contraindications to performing a direct pulp cap on a primary tooth except: Radiographic evidence of internal resorption Excessive bleeding A pinpoint exposure with little or no bleeding Spontaneous pain from the tooth 4. In primary dentition, cusp of carabelli is seen in Maxillary first molar Maxillary second molar Mandibular first molar Mandibular second molar 5. Acid etching was introduced by Brown (1945) Buonocore (1955) Wilson and ‘Kent (1972) Bowen (1965) 6. Neonatal teeth are Present within 45 days of birth Present at birth Present 180 days after birth Erupt within 30 days of birth 7. The success of a sealant retention depends mainly on Proper washing of occlusal surface Proper isolation Etching Washing after etching 8. As compared with permanent teeth, primary teeth have: Pulp horns further away from the tooth surface Thicker and shorter roots Increased number of accessory canals in pulpal floor Smaller pulp relative to crown size 9. The concept of window of infectivity was introduced by Harris Caufield Tinnanoff Garcia-godoy 10. When treating rampant dental caries the first step is to Perform a prophylaxis instruct in oral hygiene and watch for improved habits Perform a diet analysis and apply topical fluoride solution to all teeth Excavate softened tooth structure and temporize with zinc oxide eugenol Restore all teeth with stainless steel crown 11. The definition of primate space is: The space distal to the mandibular primary canines and distal to the maxillary primary canines The space mesial to the maxillary primary canines and distal to the mandibular primary canines The space mesial to the mandibular primary canines and distal to the maxillary primary canines The space mesial to the maxillary primary canines only 12. For placing a stainless steel crown, the word festooned means Stretching Cutting Crimping Polishing 13. Your patient is 9 years old. The mandibular left first primary molar has a large, carious lesion on the distal and on the occlusal and the tooth has greater mobility than what you would normally expect. You should _____. Perform a pulpectomy Extract the tooth and consider space maintenance Take a radiograph of the area Perform a pulpotomy 14. The crowns of all 20 primary teeth begin to calcify between: 4 to 6 months in utero 2 to 3 months in utero 1 to 2 months in utero 8 to 9 months in utero 15. Preventive resin restoration is used In cavitated pit and fissure sealants In non accessible proximal areas In deep caries Used in non cavitated pit and fissure sealants 16. Which of the following can be used as best root end filling material MTA Amalgam Calcium hydroxide Zoe 17. The name early childhood caries (ECC) was given by Kroll Davies Moss Horowitz 18. In the primary dentition, the mandibular foramen is located where in relation to the plane of occlusion? Higher than the plane of occlusion Much higher than the plane of occlusion The same level as the plane of occlusion Lower than the plane of occlusion 19. Primary function of MTA is Restoration in deciduous anterior teeth Apexification in an immature traumatised pulpless teeth Root canal restorative material in deciduous teeth None 20. A permanent incisor with a closed apex is traumatically intruded. What is the treatment of choice? Gradual orthodontic repositioning and conventional endodontic therapy Gradual orthodontic repositioning and calcium hydroxide pulpectomy Surgical repositioning and conventional endodontic therapy Surgical repositioning and calcium hydroxide pulpectomy Loading … Question 1 of 20
