Smart dental mirror lets patients see inside their mouths

California-based digital imaging company Omnivision Technologies and dental products firm SmartMirror have invented a wifi-enabled smart dental mirror. The device sends images and video from inside the mouth in real time to a connected tablet.
The companies unveiled details of the product at this week’s MD&M West conference in Anaheim, California.
This mirror helps dental professionals and patients see inside the patient's mouth during exams and procedures. The sapphire mirror is similar in size and weight to a standard dental mirror, which is made possible by Omnivision's OVM6946 Camera Cube Chip wafer-level camera module.
Some patients mistrust dentists and fear they will suggest unnecessary and painful treatments. As a result, dentists face resistance to treatments they believe are necessary for a patient's health. The SmartMirror is designed to alleviate these concerns and improve the communications between dentists and patients.
Its sapphire mirror provides 12x magnification and won't scratch or fog up like a standard mirror, and the 36 integrated LEDs with adjustable intensity offer brighter illumination when needed.
"We tell dentists that the SmartMirror changes everything by putting their eyes in the mouth of the patient, removing the anxiety many patients feel when they can't see what is happening," said Dan Harkabi, CEO of SmartMirror. "When we first came up with the idea three years ago, we didn't know if a commercial product was feasible. Omnivision's Camera Cube Chip technology has allowed us to bring this amazing product to market."
The OVM6946 module is built on the firm's OmniBSI+ pixel architecture and can capture 400 x 400 resolution video at 30 frames per second, providing a 120-degree diagonal field of view and a focusing range from 3mm to infinity. The module measures 1.05 by 1.05 by 2.27mm, which makes it small enough to embed seamlessly within the 4mm thick mirror.
The module has also been integrated into a number of single-use medical devices for endoscopy, an application where small size is equally important.
"We appreciate the opportunity to partner with SmartMirror to create this breakthrough product and expand the application space for our successful Camera Cube Chip modules," said Tehzeeb Gunja, principal marketing and business development manager at Omnivision. "Our camera is completely invisible to the user, and dentists and hygienists don't need any additional training to use the SmartMirror."
The mirror is in pilot testing with 200 dentists, and well over 2000 inspections and procedures have been performed using the device. It is expected to be available in mass production in Q2 2019.
