The number one reason dentists don’t have digital radiography is the cost. However if you ask most dentists they have no idea what they are paying now for x-rays.
According to the ADA the cost of a single film to the dentist is $1.10. That includes the film cost, about 40 cents as well as the cost of chemicals, processor, mounts etc.
The typical dentist takes 500 to 600 films per month. To get your number check your supply bill and see how many boxes of film you are using.
Do the math: 550 x $1.10 = $605 x 12 months = $7,260 per year in x-ray expenses.
A digital sensor will pay for itself in about a year just on the hard cost savings. If you include the time saved the ROI is even faster.
