If you get a good set of intraoral digital photos and x-rays you can do much of the charting at your desk. You no longer need to be chairside with the assistant calling out findings while she scribbles things down on paper. This is especially true with existing restorations, broken teeth and other conditions. You can also make a treatment plan from the digital photos and x-rays.
If you have a good set of intraoral photos you could even use them as your existing record rather than trying to put it on the paper chart.
If you ever are challenged in court your photos of before after and even during treatment will be the best documentation you can ask for.
We should develop clinical protocols to include photos on every new patient just as we take radiographs on every patient.
