The number of fontanelles present at birth is4268Question 7 of 20 8. Difficult to seal teeth include all the following exceptThe partially erupted permanent first molarThe fully erupted premolarThe partially erupted premolarThe partially erupted permanent second molarQuestion 8 of 20 9. A 4 yr child has a normal complement of primary teeth but they are grey and exhibit extensive occlusal and incisal wear. Radiographic examination indicates some extensive deposits of secondary dentin in these teeth. This condition isAmelogenesis imperfectDentinogenesis imperfectaNeonatal hypoplasiaCleidocranial dysostosisQuestion 9 of 20 10. In primary molars, radiographic bony changes from an infection are initially seenin the furcation area.at the apices.at the base of the developing tooth.at the alveolar crest.Question 10 of 20 11. A purulent lesion in the facial vestibule of an 8 year old patient is most likelyAn infected apthous ulcerAn isolated herpetic lesionAn odontogenic fistulaA pyogenic granulomaQuestion 11 of 20 12. All of the following are true when comparing the normal child periodontium to the normal adult periodontium except:The alveolar crest is flatterThere is greater blood and lymph supplyAttached gingiva is not as wideThe cementum is thicker and more dense than that of the adultQuestion 12 of 20 13. Which milestone of a child coincides with the eruption of the 1st primary molarsStanding without supportBowel controlFocusing on lightMaking 3-4 word sentencesQuestion 13 of 20 14. Histologically, the congenital epulis of newborn exhibitssparse lymphocytes, stromal cells and fibrosisnuclear pleomorphism, hyperchromatism and bizarre cell formssheets of large closely packed cells, showing fine granular eosinophilic cytoplasmsheets, of closely packed cells resembling plasma cellsQuestion 14 of 20 15. The DMF (decayed, missing, filled) index for dental caries in adultsincludes teeth missing for any reason.measures dental caries experience.does not apply to all populations.ignores recurrent dental caries.Question 15 of 20 16. Why are implants not generally performed on a 12-year-old patient with congenitally missing lateral incisors?The implants will appear to submerge as the child gets older.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.Question 16 of 20 17. When a pit and fissure sealant is placed over early but noncavitated cariesthe caries will be arrested only if it is a primary tooth.the likelihood of caries progression is reduced.bacterial loads generally increase under the sealant.the sealant retention rate is greatly reduced.Question 17 of 20 18.
