CDCA DSE taken Aug 2020

Case: Pregnant women with a PCN allergy who answered Yes on Health Form to "Hx of Infective Endocarditis" with her written explanation of "rheumatic fever and heart murmur". ABX? I put that "No ABX are indicated" but read AHA guidelines on hx of IE. Options included 4 abx's (including Clarithromycin, Cephalexin) and option that abx is not needed. Not sure if since she wrote "yes" on hx of IE that it still needs it, even tho rheumatic fever/murmur do not. Case: (Pregnant women with chronic perio) reference to Perio Charting asking if apical migration 1mm and now PD is 2mm, what is attachment regained? 1mm,2mm,3mm,4mm (?) Don't know. Understand CAL, PD and FGM-CEJ Perio Case: Which tooth/surface appears to have most severe vertical bone loss? I think 13(D). Other options were mesial and distal of lower posterior left and right and lower centrals. Read x-rays and pay attention to surfaces Case: Male with kidney disease (with no cost barriers looking for comprehensive prosth plan) What is the disadvantage of a PFM bridge in comparison to a metal (further description of metal, can't remember): durability? (other option- cosmetics)
