As you have the bar code function it would be good if I could (in the simplest form). add materials to a data base with details such as lot numbers & expiry dates which then generates a bar code sticker which can be applied to the material or just on a sheet, then when you scan the job bar code you can then scan the material bar code and save the materials info against that patients work, helping to comply with MDD making it less of a literally a paper trail and more pc based.
You could then go on to develop a search system then if there is a material problem it would generate all the jobs that used that material to be able to do a recall and email a list to the dentist of patients that have that material.and developed further it could also do a stock control system too so you know of wastages etc.
