When you are making the clinical notes it asks you to enter the surfaces or quadrant for a restoration or specific procedure. If you want to go back and read the notes, the only way you can see the surfaces is by amending the note. It would be nice it if was in the main line for clinical notes. There are 2 empty columns that are currently not being used. Make one for the surfaces or quadrant and get rid of the other one and make more room in the Ref column.
