1. Why are implants not generally performed on a 12-year-old patient with congenitally missing lateral incisors? The gingival tissue will recede as the child gets older. Waiting for the crowns is too much of an esthetic issue with most children that age. The patient would likely not be able to tolerate the surgical procedure. The implants will appear to submerge as the child gets older. 2. Which of the following is the most recommended endodontic obturating material for deciduous teeth? Zoe Kri paste Maisto’s paste Ca(oh)2 paste 3. A young permanent incisor with an open apex has a pinpoint exposure due to a traumatic injury that occurred 24 hours previously. The best treatment is _____. Initiate a calcium hydroxide pulpectomy Initiate conventional root canal treatment with gutta-percha Place calcium hydroxide on the pinpoint exposure Open the pulp chamber to find healthy pulp tissue and perform a pulpotomy 4. In a stainless steel crown on a deciduous molar with overhanging margins, gingival pain and inflammation occurs due to: Crown margins causing irritation Excess cement Engaging undercut Plaque retention 5. There is a marked increase in the incidence of interproximal caries during the age of 7-9 years 2-3 years 3-5 years 6-8 years 6. A light bluish dome shaped lesion on the inside lip of a 2 yr old child is mostly Melanoma Mucocele Hematoma Hemangioma 7. 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? It has been demonstrated that formocresol may cause spontaneous abortion. 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. Application of formocresol is a clinically timeconsuming procedure. 8. 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 alveolar crest is flatter The cementum is thicker and more dense than that of the adult There is greater blood and lymph supply 9. How much fluoride, in ppm, is contained in commonly used toothpastes? 12,300 ppm 5,000 ppm 9,000 ppm 1,000 ppm 10.

Following types of fissures are not caries susceptible I and K U and V K and V V and I 12. Chronic pulpal involvement in a deciduous molar is first manifested as Widening of pdl in apical 1/3 rd Normal pulp Radiolucency in furcation area Radiolucency at apex of root 13. Where do lesions commonly occur in the primary form of acute herpetic gingivostomatitis? Tonsils, hard and soft palate Tongue All of the above Buccal mucosa 14. Differences between child and adult patient are Both (a) and (b) Dentist to the parent relationship Dentist to the patient relationship Physical, emotional and psychological development 15.

The best filling material in deciduous teeth for RCT Calcium hydroxide Zinc oxide eugenol Amalgam Gutta percha 17. The most successful treatment for a vital primary second molar with a large carious pulp exposure is Indirect pulp capping Pulpotomy with formacresol Pulpotomy with calcium hydroxide Pulp capping with calcium Hydroxide 18. Which of the following are advantages a light cured materials over chemical cure sealants? Working time is longer All of the above Better physical and mechanical properties Less chance of incorporation of air bubble 19. Recommended brushing time in children under supervision of parent is 1 minute 3 minutes 5 minute 15 seconds 20. Which tooth is the only anterior tooth in either dentition to have a shorter inciso-cervical height than the mesio-distal width?
