Researchers present key findings on detection of caries around the margins of amalgam restorations using four technologies

This study found that The Canary System ® can detect caries under the intact margins of amalgam restorations more accurately than Spectra, DIAGNOdent and visual examination. & nbsp; < /div > < div class= " MsoNormal " > < br / > < /div > < div class= " MsoNormal " > Finding caries beneath intact amalgam margins is a challenging clinical problem because of the nature of the material. & nbsp; Amalgam is dense, radiopaque and reflects light from its surface. & nbsp; The study found that visual examination could not detect caries. & nbsp; The glow or fluorescence from the amalgam prevented Spectra from detecting any marginal caries. & nbsp; DIAGNOdent was unable to consistently differentiate sound from carious tissue at various distances from the amalgam margins. & nbsp; It was able to detect between 45% - 74% of the lesions beneath the amalgam depending upon the distance from the margin. & nbsp; The Canary System was able to detect 95% of the lesions around the amalgam margins. & nbsp; This study demonstrated that The Canary system is a valuable diagnostic tool for detecting caries that develop around and beneath the margins of amalgam restorations. < /div > < div class= " MsoNormal " > < br / > < /div > < div class= " MsoNormal " > “The Canary System provides dentists with the ability to detect and monitor tooth decay beneath the edges of fillings, crowns and bridges; one of the most common clinical conditions that would lead to the failure of these restor...
