Decide what type of equipment and how many units you need before you start shopping around.
Take a look at your office's setup. Some dental X-ray machines are attached to a wheeled floor stand. Others need to be mounted on the wall. See which type works best in your facility.
Look online. There are databases that list all the companies that specialize in dental X-ray equipment. Also, ask your medical supply dealer for recommendations.
Compare prices. Dental X-ray units cost several thousand dollars apiece, so it's a big investment.
Look for units with a push button that can be operated from outside the room, if needed. Some come with a remote control panel, too.
Buy X-ray machines that are made of high quality materials. Many have glossy finishes, specifically so they can be cleaned easily. This helps keep your working environment hygienic.
Find a reputable dealer. Ask other dental offices where they bought their equipment. Get information on the company's exchange or return policy, just in case.
