Figure 429 is a case in which we see an imperfect canal filling, andevidence of osteoblastic stimulation—which is probably infective in nature—at the apex of the second bicuspid. In this case it seems that we havepractically no bone decalcification. While the canal filling in this casereaches the end of the root, I consider it imperfect because, judging fromthe buckled, bent condition of the gutta percha point, the canal filling doesnot fill the canal solidly
