1. Your patient is 4 years old. The maxillary right primary central incisor was traumatically avulsed 60 minutes ago. What is the treatment of choice?Replant, no splint, primary endoReplant, splint, formocresol pulpotomyNone of the aboveReplant, splint, primary endoQuestion 1 of 20 2. A traumatically intruded deciduous maxillary central incisor should be allowed to reerupt ifthere is no danger to the permanent successorit is not possible to splint the toothit cannot be extractedother deciduous teeth are also intrudedQuestion 2 of 20 3. Stony hard on percussion, tooth stops erupting. Such tooth showsInternal ResorptionMesial migrationExternal ResorptionReplacement Resorption AnkylosisQuestion 3 of 20 4. Which of the following factors in the Stephan's curve is related to the caries incidence and the sugar intakeQuantity of sugar intakeFrequency of sugar intakePh of plaquePhysical form of sugarQuestion 4 of 20 5. Preventive resin restoration is usedIn deep cariesIn cavitated pit and fissure sealantsIn non accessible proximal areasUsed in non cavitated pit and fissure sealantsQuestion 5 of 20 6. When a pit and fissure sealant is placed over early but noncavitated cariesthe sealant retention rate is greatly reduced.bacterial loads generally increase under the sealant.the caries will be arrested only if it is a primary tooth.the likelihood of caries progression is reduced.Question 6 of 20 7. Most common cause of gingivitis in children below 5 yrs of age:MalocclusionLocal irritantsVitamin deficiencyHerpesQuestion 7 of 20 8. According to Cron, the tooth starts erupting afterThree fourths of the root formation is completeOne fourth of the root is formedThe entire root is formedOne half of the root is formedQuestion 8 of 20 9. The most important morphologic or histologic consideration in cavity preparation in primary teeth isThickness of enamel and dentinDirection of roots below CEJDirection of enamel rods cervicallySize of primary molarsQuestion 9 of 20 10. Still's disease is a juvenile form ofcandidiasisdiabetes mellitushypertrophic cardiomyopathyrheumatoid arthritisQuestion 10 of 20 11. The union of two teeth by the crowns isConcrescenceGeminationAnkylosisFusionQuestion 11 of 20 12. To prevent mesial drift of a permanent first molar, the ideal time to place a distal extension space maintainer isas soon as the tooth erupts through the gingival tissue.as soon as the extraction site of the primary second molar has completely healed.after the permanent second molar has erupted.immediately after extraction of the primary second molar. Question 12 of 20 13. A light bluish dome shaped lesion on the inside lip of a 2 yr old child is mostlyHemangiomaMucoceleHematomaMelanomaQuestion 13 of 20 14. A narrow continuous line or a series of brown dots which follow the contour of gingival margin of the posterior teeth in children is known asNeonatal lineMesentric lineDevelopmental lineBurtonian lineQuestion 14 of 20 15. Formocresol has been shown to have a very good success rate when used as a medicament for pulpotomy procedures. Why is there continued interest to find another medicament that performs as well as or better than formocresol?Application of formocresol is a clinically timeconsuming procedure.Formocresol is toxic and there is possible bloodborne spread to vital organs.It has been demonstrated that formocresol may cause failure to develop adequate lung capacity in children.It has been demonstrated that formocresol may cause spontaneous abortion.Question 15 of 20 16. The most appropriate management for the replantation of an avulsed permanent tooth ison the site where avulsion happened, after soaking it in milk for 5 minutes.on the site where avulsion happened, immediately after avulsion.upon arrival at a dental clinic, within 60 minutes of avulsion.upon arrival at a dental clinic, after soaking it in saline for 5 minutes.Question 16 of 20 17. Juvenile periodontitis is due toDefect in monocytesIncreased phagocytosisDefect in neutrophil chemotactic activityDecreased phagocytosisQuestion 17 of 20 18. A severe blow to a permanent anterior tooth not resulting in fracture, commonly leads topermanent increase in mobilitypulpal death, in the absence of treatmentdeath of the pulp, despite treatmentfracture of the involved boneQuestion 18 of 20 19. Chronic pulpal involvement in a deciduous molar is first manifested asNormal pulpRadiolucency at apex of rootRadiolucency in furcation areaWidening of pdl in apical 1/3 rdQuestion 19 of 20 20.
