2014 DENTAL QUIZ BEEGame mechanicsQuestions are composed of 16 easy questions, 12 moderate questions and 5 difficult questions.All questions and answers are screened and are final.The first group to buzz in will be given 10 seconds to answer. in the event, that the group were not able to answer, the other 3 teams can steal.In case the groups were not able to answer, the game master will proceed to the next questionAt the end of the 5th difficult question, the group with the highest score will be announced as WINNERS.

Eight primary incisors were replacedby the 8 permanent incisors (20 8 = 12 primaryteeth remaining). The child describedabove is at the end of the early mixed dentitionphase and is most likely 81/2 years old.Answer A is incorrect. At most, only 8 permanentteeth (4 first molars and 4 [upper andlower] central incisors) would be expected atthis age. All primary teeth except the lowerand upper central incisors would remain(20 4 = 16 primary teeth).Answer B is incorrect. It is likely that thepermanent maxillary lateral incisors wouldnot have erupted by this age (usually aroundage 8-9).Answer D is incorrect. At the very least, onewould expect the mandibular canine and/orthe maxillary 1st premolar to have erupted atthis age, yielding 14-16 permanent teeth and8-10 primary teeth.Answer E is incorrect. By this age, no primaryteeth should remain. The permanent2nd molars likely would have erupted (atabout age 11-13).118 YEARS OLDGENERAL ANATOMYAcromegaly is caused by overproduction of what hormone?growth?/13somatotropinDENTAL MATERIALSIt occurs when impression absorbs water which expands the dimension of the impression15Imbibition
