Caries detection
Until KaVo introduced the DiagNodent, the tools of the trade were a sharp explorer, an accurate radiograph and an opinion of the doctor. In school we were taught to “watch” lesions until they were “large enough to fill”. This of course was under the tradition of GV Black preparations and restorations filled with amalgam. With the advent of bonded restorations and flowable composites, as well as materials laden with fluoride and bonding agents with disinfectant properties, restorations are now indicated at the beginning of the caries experience. The DiagNodent has technology to read the “catch” or decalcified area and give a quantitative answer to the age old question- “is it a watch?” Using laser fluorescence this unique device reads the density below the enamel. It also is effective finding the “fluoride bombs”- caries that has developed under rock hard enamel which may not even have a notable “catch”. A digital display with an optional audible sound alerts the operator as well as the patient if there is a restoration necessary. The patients become part of the diagnostic decision making this an educational tool as well. This is a must have piece of equipment for every general practitioner and hygienist. Period.
Another useful device is the DIFOTI. This is essentially a transillumination light with a video capture. It allows the practitioner and patient to visualize caries and fractures in teeth in a less abstract method than radiographs. Some incipient caries can be visually detected and in some cases, earlier than radiographs.
A new device has been introduced by OMNII. The Detektar locates and documents decalcifications and pre-carious areas. With the aggressive use of fluoride and new re-calcification products such as SootheRX the patient can be treated with a preventive and pre-emptive regimen.
Ozone therapy is currently being used to treat all of the
early situations mentioned. At press time this is not approved for use in the
