Why work with a microscope?

Why work with a microscope?

The operating microscope (OM) is not restricted to endodontics, nor is it an instrument only designed to search for the entrance of the canals or to check the quality of a preparation. It can be used permanently in omnipractice and replaces the use of magnifying glasses in a very favorable way. The fatigue of your eyes when focalizing (with or without magnifying glasses) disappears with the microscope because the eyes look at infinite and can rest in an operation field, which is always perfectly lit without any shade.

The magnification trough the eyepiece gives you an extraordinary vision in 3D, which allows you to improve the precision and the quality of your work, and therefore to increase your satisfaction. The more, you eliminate the toxic positions of your spine; the microscope imposes a physiological position, which often relieves from spine problems of which many dentists suffer.

Adding a camera to the OM with a screen for the patients allows an unequaled communication with them and their accompanying persons. All the explanations become clearer.

Comments of Professor Pierre Machtou, DDS, MS, PhD
 Today, the use of optical assistance in odontology cannot be ignored by whoever wishes to give the best care to his patients. Magnifying glasses are of good help, but are not without shortcomings. They need a light source, a precise working distance and in most of the cases they are associated with a deficient posture of the practitioner. The operating microscope (OM) makes up for all these inconveniences by supplying a vision to infinite, an incomparable lighting and a confortable working position generating no fatigue.

A common and tenacious opinion consists of believing that the use of an OM is exclusively dedicated to endodontics. Nothing could be further from truth, because it is addressing all the procedures of dentistry. In this age of mini invasive dentistry, the increased visual perception of details delivered by an important magnification increases the capacity of the practitioner to diagnose beginning or recurrent cavities as well as cracks, to distinguish the different colorations of tissues, to make preparations at minima, to refine the polishing quality of restorations, to evaluate the finishing quality of prosthetic preparations and of the material-tooth interface, to adjust with precision the occlusal contacts and to realize many other procedures…

Of course, a certain time of learning remains necessary to reach efficient working with an OM and this essential step may discourage potential users. Unfortunately, practically no information was available so far to help practitioners to rapidly become performing with an OM and to avoid thus groping, waste of time and sometimes frustration.  

 Fortunately, a double DVD developed by Denis Honegger, comes at the right moment to fill this gap. Denis Honegger is an omni-practitioner who has immediately perceived the potentialities of working with an OM in daily practice. Having himself encountered all the difficulties and obstacles related to learning, his long experience has allowed him to codify all the steps of working with an OM, of working with four hands and of the ergonomic in the working space.

The first DVD helps the practitioner straight away to familiarize himself with the different components of the OM, and this for the various brands available on the market. Afterwards, with the help of simple exercises, the subtleties of working in indirect vision are rapidly understood and integrated. Viewing the working positions in the different sectors as well as the role of the assistant will save a lot of time for the beginner.

In the second DVD, four clinical demonstrations on a patient in restorative and prosthetic dentistry show the practical application of the entire information described initially.

Throughout watching these two DVDs, the pedagogic impact of the image is potentiated by an exhaustive comment of extreme precision. In short, I can but recommend this unique pedagogic tool without restriction to all practitioners interested in using an OM in omni-practice, but who so far hesitated to jump ahead!
