1. Which of the following local anesthetic techniques is recommended for anesthetizing a primary mandibular second molar which will be extracted? Inferior alveolar, lingual, and buccal nerve block Buccal and lingual infiltration adjacent to the second primary molar Inferior alveolar nerve block and lingual nerve block Inferior alveolar nerve block 2. Localized aggressive periodontitis in the primary dentition is seen most commonly in the primary molar area. It is most common in Asian children. The first statement is false and the second statement is true. The first statement is true and the second statement is true. The first statement is false and the second statement is false. The first statement is true and the second statement is false. 3. Congenitally missing teeth are the result of failure in which stage of development? Initiation Morphodifferentiation Calcification Apposition 4. The KRI paste is composed of Parachlorophenol,camphor and menthol Calcium hydroxide and iodoform Iodoform and ZOE Iodoform,camphor,parachlorophenol and menthol 5. Pulp mummification is indicated in Deep caries in a symptomatic vital teeth Non vital teeth Traumatic exposure of a vital tooth with open wide apex Traumatic exposure of a vital tooth 6. In child with class II restoration fails because of Insufficient width Proximal box fracture Increased labiolingual width Marginal fracture 7. The form of rampant carries in young patients after radiotherapy for cancer treatment is Rampant infant and early childhood decay Rampant caries Radiation caries ECC 8. The enamel rods in the gingival third of primary teeth slope occlusally instead of cervically as in permanent teeth, and the interproximal contacts of primary teeth are broader and flatter than permanent teeth. The first statement is true and the second statement is false. The first statement is false and the second statement is true. The first statement is false and the second statement is false. The first statement is true and the second statement is true. 9. Stainless steel crown are contraindicated in Amelogenesis imperfecta Medically compromised patient After endodontic therapy Rampant caries 10. The normal SNA is 90-92 degrees 70-72 degrees 80-82 derees 60-62 degrees 11. 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 It is too early in life to make final predictions concerning development of any permanent teeth The child will probably never develop second premolars These teeth may develop later 12. The name early childhood caries (ECC) was given by Davies Moss Horowitz Kroll 13. How are baby breath located while sucking milk Due to short and wide tongue Due to short soft palate Due to high placed larynx Due to short pharynx 14. In the maxilla the molar tooth germs develop, with their occlusal surfaces facing first Distally Mesially Buccally Lingually 15. The calcification of maxillary and mandibular permanent first molars occurs at what age? 10 to 12 months Birth 1.5 to 2 years 3 to 4 months 16. All of the following are true when comparing the normal child periodontium to the normal adult periodontium except: Attached gingiva is not as wide The cementum is thicker and more dense than that of the adult There is greater blood and lymph supply The alveolar crest is flatter 17. Preventive resin restoration is used In non accessible proximal areas In deep caries In cavitated pit and fissure sealants Used in non cavitated pit and fissure sealants 18. The most common congenitally missing primary tooth is the: Primary mandibular canine Primary mandibular first molar Primary maxillary canine Primary maxillary lateral incisor 19. Which property of pit and fissure sealant is most important? Adequate working time Low volatility Moderate solubility and water sorption Thermal conductivity higher than teeth 20. Why are rounded internal line angles desirable in the preparation of amalgam restorations in primary teeth? They increase resistance They conserve tooth structure They increase retention They decreases internal stresses in the restorative material Loading … Question 1 of 20
