Objectives: To evaluate the performance of an oral scope using blue LEDs (Penscope, J.Morita, Japan) in vitro and in vivo. Methods: In vitro study: Ten extracted human teeth with caries were used. Four were active and other six were arrested caries. Caries was removed using a steel bur checking with an oral scope. After removing, Caries Detector (Kuraray, Japan) was applied on the cavity to detect remaining caries. In vivo study: The oral pictures of a 32 year old male were taken with an oral scope before and after professional tooth cleaning and the pictures were evaluated and compared with the record of an oral examination. Results: In vitro study: After removing active caries, the cavity was light stained with Caries Detector. The arrested caries lesions were dark and were hardly emitted by an oral scope. In vivo study: Dental calculus and plaque were emitted red light in an oral scope. It was also easy to identify the materials of the restoration i.e. metal bonded porcelain crowns and composite resins. It was suggested that the use of the Pen Scope should make informed consent to patients easier and more effective. Conclusion: Caries, plaque, calculus and resin restoration were able to be identified by means of an oral scope. Caries indicated by an oral scope and by Caries Detector were different.
