q 119 - in the radiograph the answer was void . I feel a void is small gaps that are formed due to poor compaction during obturation . The x ray shows Gutta percha that might have been removed for a post , the post may not show because it may be a fiber post and the radio opaque material is the resin cement . You can see the apical seal (as if the gutta percha was cute and removed ) not voids .
q 20 - I also felt it here it was risky to say voids , if it was for the root that has the long post , because i also feel here that the gutta percha is removed for post placement and not really a void during obturation , yes there is a broken instrument and its underfilled , but i felt saying there is voids is risky
q 111 - isn't there calculus on the mesial of 17 ?
q 4 - I agree its aggressive but i was confused between localized and generalized , what i did is counted that there was attachment loss in 41% of the sites so I considered it as generalized aggressive perio ;/ . in order for it to be generalized does it have to include teeth other then first molars and incisors ?
