Caries detection has become *much* more than just evaluating how “sticky” a pit or fissure feels with a dental explorer.  In fact, the explorer itself is a pretty poor tool for detecting carious lesions in teeth that are not exhibiting obvious cavitated lesions.  Because of that I have pretty much done away with sharp explorer diagnosis when doing clinical exams.  The most predictable and reliable diagnostic devices currently available use some type of digital imaging with light waves that penetrate the intact structure and reveal lesions that are hidden under what appears to be healthy enamel.

Of those devices, The Canary System provides very accurate and reproducible results.  Here is some news about the device that is pretty much  “hot off the digital press”:

The Canary System is sufficiently sensitive to detect early white spot lesions according to a study presented at
the International Association for Dental Research in Vancouver, Canada by Dr. Clif Carey, University of Colorado
Anschutz Medical Campus, School of Dental Medicine. By detecting early white spot lesions, The Canary System
gives an early warning of caries or tooth decay activity allowing for early intervention to preserve the integrity of
the tooth.

Caries or tooth decay will typically start as a white spot. These white spots may appear on various tooth
surfaces and are an indication that destruction of the crystal structure of the tooth has started below the tooth
surface. As the decay process advances, the white spot may not
change in appearance but the underlying tooth structure is being
slowly disrupted and/or destroyed. Waiting for a cavity to
develop is not really the appropriate approach to treatment.
The study also concluded that “The larger Canary Number scale
allows for greater sensitivity in the detection and classification of
the severity of the white spot lesion and is better than a visual

“The Canary System provides dentists with the ability to detect
and monitor tooth decay on all tooth surfaces, beneath the edges
of fillings, crowns and bridges and underneath sealants. X‐Rays
can only aid clinicians to diagnose decay on the sides or
interproximal areas of teeth once the decay is well advance into
the tooth”, said Dr. Stephen Abrams, co‐founder of Quantum
Dental Technologies. “Visual detection provides very little information on what is occurring beneath the tooth surface. Early detection of tooth decay, before it is seen visually or on an x‐ray means that dentists can treat problems before the decay has destroyed large amounts of vital tooth structure.”
The Canary System, with its unique crystal structure diagnostics, can quantify, image, monitor and record
changes in the structure of enamel, dentin and cementum. It can detect caries beneath opaque sealants, around
the margins of restorations, around orthodontic brackets and beneath interproximal, occlusal and smooth
surfaces. The Canary Cloud enables dentists to view and manage this data and track Canary usage in the office.
The Canary Patient report provides the patient with information on the examination and engages them in their
oral health care.

  1. Presently a days center’s assume a significant job in the strength of the client and additionally maintins the undertaking and decreases the work process. It can likewise oversee various verticals of their activity, for example, arrangement planning, tolerant record the board, charging and invoicing, book keeping and that’s just the beginning. This gives an upper edge to the performence of the application just as the easy method to work and get the best outcomes.
