USB Connectivity: Most intraoral cameras are digital and an easy-to-use USB connection is crucial. This easy connectivity allows you to take the camera from room to room, eliminating the need to have one for every operatory. Relying on docking stations adds an unnecessary cost and reduces portability of the camera.
Capture Button: The capture button should be positioned where you can snap an image no matter the orientation of the camera in the mouth. Some intraoral cameras have a swipe function to capture the image, eliminating the need to push a physical button. This is nice because pushing a button might move the camera and blur the image.
Construction: While plastic or steel construction may not make a difference to the captured image, a stronger intraoral camera will tend to last longer. Keep in mind that sturdier construction may increase the overall weight of the camera and a lightweight camera might be easier to use.
Resolution: A higher resolution intraoral camera will usually capture images with better clarity.
Intraoral vs. Macro: Many intraoral cameras allow for a change in focal distance to let you capture a full arch or even an extraoral shot of the patient. While it doesn’t come near the quality of taking an extraoral picture with a digital SLR camera, this feature can be good for a quick image which can be added to a patient’s chart.
Light Source: Most USB intraoral cameras feature LED technology to light your subject. Because LEDs provide more than enough light for an intraoral image, this a less crucial attribute to worry about.
Software: It is important to know if the software or drivers that come with the camera will be compatible with your existing practice management or imaging software. You may see some describe their camera as TWAIN compliant. This is a common imaging standard outside of dentistry allowing different cameras to work with different software applications.
Warranty: As with any piece of equipment, know the period of time for your warranty. Accidents do happen.
