Adequate tooth shade analysis as reproduction of colors in order to maximize simulate natural appearance is one of the most difficult problems of practical dental patients during rehabilitation through different types of restorations.

shade matching system continue to evolve, but so far none of them can not provide enough objective result. Different color analysis protocols teeth are known in the market for many years, but most of those only provides efficiency for posterior teeth, or just for the initial analysis of the frontal area of ​​aesthetics, based on the still image settings, and modifications of algorithms visualization and processing.

This category is devoted to a number of scientific articles, but for this article, the author personally examined the views of many technicians, for whom the problem is the same date as the existing issues of adequate preparation of the teeth and accurate prints.

The action of many factors makes it difficult to objectification process color dental analysis and its reproduction, one of which is a different coverage area of ​​interest, which distorts the effect of color of the final restoration. Problems begin with the fact that different manufacturers and companies have not come to a consensus decision, what kind of coverage is best suited for the analysis of the right color, but the possibility of correcting the source of such parameters helps dentists to carry out this procedure in the most appropriate conditions. On the other hand, the color reproduction process is burdened by an individual difference of perception among the people involved in the dental treatment. On the last factor also affects what kind of shade matching system used by each of the participants in the rehabilitation process.

Oddly, but in today’s time a single standardized system of colors of various brands of ceramic materials is also no further utrudnyaet already complex manufacturing process vysokoestetichesky restorations. Furthermore, it should be noted that the complex morphology of a tooth, its shape, surface texture and an appropriate shine – all of which are those parameters, without which the process of treatment of any of the tooth is simply not enough. For a better understanding of the issue of perception of color, there are many dental and nestomatologicheskoy literature, so in this article, the author will try to focus the reader’s attention to the technique of the calibrated analysis software for the objectification of all possible shades of parameters in clinical practice.

The impact of digital photography

Over the past few years, digital photography has become a tool for planning dental treatment and communication between members of the patient’s rehabilitation process. To ensure the necessary analysis using shades of the photos should be considered the original settings of the image and the specifics of its receipt. In addition, different cameras can shoot the same subject quite differently, causing deviations in the process of objective perception of color. Thus, the first step to a successful analysis of the parameters of tooth shades – is the right choice with the ability to balance setting, the camera in white, which helps to significantly compensate for the difference in color perception (author’s note: Information about the choice of the camera and flash, as well as the specific camera settings, especially for the general dental pictures in great detail is provided in other articles, to which the reader is also advised to read).

The most important aspects to ensure good dental photography is:

  1. Using a digital single-lens reflex (SLR) camera with the ability to change the lens;
  2. Recording images in RAW format;
  3. Using a custom white balance settings;
  4. Using the manual exposure shooting shades.
