Caries Detection With Two Different Caries Detecting Devices

The teeth being assessed will be cleaned of any debris ,plaque and calculus. The areas being assessed will be air dried. A dry field will be maintained using cotton rolls and a saliva ejector. Lumicare rinse will be applied onto the test areas for 30 seconds and the excess removed using a saliva ejector. The sites will then be rinsed with plain water for 10 seconds and excess will be removed using high volume suction. A blue curing light will then be held 1-2 inches from the test surfaces while the examiner assesses the surfaces for the presence or absence of fluorescent illumination.

The teeth being assessed will be cleaned of any debris ,plaque and calculus. The areas being assessed will be air dried. A dry field will be maintained using cotton rolls and a saliva ejector. The QLF device will be positioned over the tooth surface to be tested and an image will be taken. The images will be stored automatically and assessed by the examiners for the presence of green fluorescence using the QA2 program (Version 1.25, Inspektor Research systems BV, Amsterdam, The Netherlands) . The trend in green fluorescence will also be calculated using this software algorithm.
