  • Objective: The aim of this study was to perform a qualitative assessment of the personal video monitor (PVM) as an accessory to the dental operating microscope (DOM). Method and materials: The PVM was attached to a color video monitor, which was already attached to a DOM through a beam splitter. One faculty clinician performed a complete oral examination on a patient wearing a binocular inclinable lens adapted to the DOM under different magnifications, while a second faculty watched the procedure simultaneously using a PVM. After completing the examination, the operators exchanged the viewing devices and repeated the procedure. Results: When compared to a standard binocular lens attached to the DOM, the second operator using the PVM had an unencumbered view of his surroundings and was able to make head movements freely. However, when comparing the resolution of the standard binocular lens to the PVM, the binocular lens provided a sharper picture with better illumination, especially when using higher magnification. Statistical analysis was not incorporated, as the goal of this experiment was to qualify rather than quantify the established PVM resolution, in this initial analysis. Conclusion: The authors concluded that the PVM attached to the video camera and the DOM allowed a second operator to watch the procedure, and it could be used as an important teaching tool. Another application is that the patient may wear the PVM while the procedure is in progress. However, the resolution in the PVM needs to be significantly improved in order to achieve an adequate level of efficiency in four-handed microdentistry.
