Ultrasonic Perio

July 29, 2010

The link below is to a DrBicuspid article (registration required). Some experts contend we will not be seeing ultrasonic diagnostics in dentistry any time soon because dental anatomy is too complex and ultrasonic diagnostics are too expensive.

Body Scanners Could Make Fitting Rooms Obsolete

July 1, 2010

This has nothing to do (directly) with dentistry. However it is interesting and it does show how scanners are being used in various ways which does relate to 3D imaging in dentistry. One step closer to the Tricorder.
Within seconds, 3D body scanners take a snapshot of the human form and produce a 3D replica, with complete measurement [...]

Caries Detection

June 4, 2010

The article is interesting but from the description the system seems to me to be a bit awkward. For example it states it can take 50 seconds to examine a single spot on a single tooth.

Optimizing the Image for Diagnosis

April 27, 2010

When looking at a radiograph for diagnosis we are looking at different tissues; soft tissue, bone, tooth, enamel, roots and the special periapical tissues. We are also looking for different pathologies including caries, bone loss, fractures, periapical lesions and so on. With an old fashioned film radiograph we have to interpret all of this from [...]
