Factors to Consider when Purchasing Dental Loupes


All dentists will appreciate the impact inadequate visualisation can have on their day-to-day practice. In cases where the treatment area is in a particularly hard to reach location, diagnosing and treating the problem can prove especially difficult.

By using dental loupes, a practitioner can enhance their practice significantly, with greater magnification and depth of vision making even the most hard to reach areas easily accessible. Dental loupes can also broaden the range of a clinician’s abilities, allowing for more precise, and ultimately, more effective treatment. A good example would be restorative treatments where loupes greatly improve the accuracy of preparations and the ability of a practitioner to match colours.


Given just how significantly a pair of dental loupes can affect your practice, it pays to consider all your options wisely before investing your hard-earned capital.

One of the first factors you will need to consider is magnification. A good level of magnification is essential to any pair of dental loupes. Ideally, loupes should be able to provide optimum image quality at 2.5x magnification, with more advanced products providing clear, crisp images up to 5x magnification. Furthermore, a practitioner should consider the size of the field of view offered by their loupes, as some dentists may prefer a larger field of view for a better overview of the treatment site, while others will require a smaller field of view for more precise, localised images.

In addition, it is essential that the dental loupes you invest in offer a good depth of field with clear, crisp optics for the accurate viewing of anatomical microstructures. A loupe that uses apochromatic technology will prevent chromatic aberration. This will ensure the magnified image you see will be as accurate as possible, with edge-to-edge clarity and no “fuzziness” around your peripheral view.

eml2If you require additional illumination, most high quality loupes will come with an optional light attachment, generally provided by a lightweight LED lamp with homogeneous light distribution for brilliant images with outstanding colour fidelity. Some light sources will even come with swing-in filters to prevent premature curing of composite materials.

Another consideration that should be made when purchasing loupes is that of working distance. Choosing the correct working distance to give the best posture is an essential part of the decision making process.

Ergonomic considerations are extremely important to a dentist, and are especially important with regards to loupes, which may well be worn day in, day out, and can potentially cause aches and pains. To try to offset this, look for a loupe that has a lightweight titanium eyeglass frame, with even weight distribution across the face and a soft, silicone “saddle” nose bridge. This will reduce fatigue and maximise comfort during long procedures.

An intuitive design can also help during surgery, as you should be able to change settings effortlessly as your treatment needs change. To this end, the loupes should have a range of tilt and declination settings for quick operation, and the eyepieces should have the ability to be easily positioned in only one adjustment. Moreover, a flip-up function will enable unobstructed vision whilst working and will also allow you to keep eye contact with the patient to put them at ease.

When purchasing dental loupes it is vital that you have assurance that they are from a reliable company who have your best interests at heart – a company that can provide expert technical support throughout your product’s life cycle.
