A loupe is a simple, small magnification device used to see small details more closely. Unlike a magnifying glass, a loupe does not have an attached handle, and its focusing lens are contained in an opaque cylinder or cone or fold into an enclosing housing that protects the lenses when not in use. Dental loupes aid dentists, hygienists, and dental therapists to devise accurate diagnose of oral conditions and enhance surgical precision when completing treatment. Additionally, loupes can improve dentists' posture which can decrease occupational strain.
Dental caries, also known as cavities, are most accurately identified by visual and tactile examination of a clean, dry tooth. Magnification enables dentists to improve their ability to differentiate between a stain and a cavity. Cavities are rated and scored based on their visual presentation. If magnification is too high diagnosis becomes difficult due to the small field of view. Treatment of dental caries, periodontal disease, and pulpal disease are aided by magnification. The dental specialty of endodontics has performed the vast majority of research regarding magnification in dentistry. Because the identification of accessory canals in addition to the primary pulp canals is essential to complete nonsurgical root canal therapy, magnification provides dentists enhanced visualization to locate and treat more obscured canals.
