Dr. C. asks:
I saw an advertisement in Dentistry Today about a new caries detection system called Caries ID, manufactured by Midwest and marketed by DENTSPLY. According to the advertisement the device, which looks like a high speed handpiece, is held over the tooth surface and a red light comes on if caries is present. It can be used for occlusal and proximal caries. Has anybody tried this and does it work? Is this any improvement over the DIAGNOdent made by KaVo? I am planning to use this primarily to detect occlusal caries. With all the adverse publicity about using a sharp explorer which may puncture an intact enamel surface over a carious lesion, I am looking for an alternative method of caries detection that is reliable.
According to the company: “The Midwest Caries I.D. uses Light Emitting Diode (LED) and fiber optic technologies to accurately detect both occlusal and interproximal caries. The presence of either type of lesion is identifi ed by 2 signals: an audible tone, and a visual signal on the tooth. It requires only a clean tooth surface, free of plaque and calculus prior to use to be effective…Lightweight and cordless for reduced hand fatigue and improved clinician comfort. LED depth penetration of 3mm. Full mouth scan in under 2 minutes. Unit lifespan of over 100 patients. Autoclavable outer housing eliminates the risk of cross contamination.”
