Full mouth x-rays

Today my patient was late for clinic because of the snow storm, and we lost a half and hour of working time. I took BWX-rays on my patient and found that they were not very good, because she had some endentulous areas that made it difficult to get the horizontal plane equal, and still get the bone height we needed to see. Well they did not turn out very well, but I ended up getting at least all of the structures in except for 1 x-ray. Then the professor told me I should take full mouth x-rays on this patient because she would be a very good canditate be able to see all of the bone loss that is in her mouth. I tried to talk through another girl to explain this to my patient because she speaks spanish. I emphasized twice about the cost being more, and the lack of being able to get her finished and cleaned that day, and she agreed. Well come to find out she got a little irritated because I guess she misunderstood. She ended up needing to leave early, and so I was very rushed trying to get everything done. My biggest mistake was not printing out a treatment plan statement first in order to ensure w/out a doubt that everything was going to be great. I guess I totally learned my lesson on that one.
