A new concept of optical anatomy
It is widespread and well established opinion that the clinical picture role should not be limited to simple, yet fundamental, documentation function, but it can effectively integrate the diagnostic process.
This is because the medicine born from the observation of reality and phenomena that it offers us and it fundamentally is, and the photographic image is a very effective way to exercise the observation, and therefore, diagnosis powers.
Photography is a diagnostic tool because it allows compress and expand time and space, and this paper purpose is to show how it is possible to further enhance this analysis and diagnosis function.
Despite the photographic medium growing diffusion, we are convinced that it is not always used according to scientific criteria; on the contrary, we think that this condition rarely performs in practice. This is because the current approach to photography, as well as the color in dentistry culture, historically based itself in a more artistic design than scientific.
Considering the current knowledge, supported by recent publications, we believe it is necessary to review the approach both photography as color phenomenon and its glossary, serious aspects and long undervalued and unrecognized. In the wake of this necessary scientific developments, it has recently proposed a new operating philosophy: Photography Based on Scientific Evidence (Evidence Based Dentistry Photography - EBDP), which emphasizes the value and the diagnostic function of the photographic image, allowing you to use the digital camera as a tool measurement - high precision - of colorimetric data.
But it is necessary to go further: this paper show how the photographic image can become an ideal instrument for understanding the anatomical and structural characteristics of the teeth and how they are related to the optical behavior of the dental material. The strong dependency between these two aspects enabled the development and definition of a new concept: that of "optical anatomy" of the tooth.
Why "optical Anatomy"? The first term is to emphasize the role of structural features - by the way, anatomical - related to the second, to highlight the role of light radiation in the genesis of aesthetic perceptions. The difference with the traditional display of optical characteristics based on "color dimension" lies, therefore, the importance given to the interaction between tooth structure and light radiation and recognizable and analyzable by photographic image.
Essentially, the optical anatomy requires the clinician to focus their attention not on color perception, subjective and elusive random phenomenon, but the characteristics of matter and light radiation that those same perceptions generated.
It is, in other words, a radical change of perspective; a traditional perceptual artistic approach, and the other, the modern scientific and realistic.
The optical anatomy is not theoretical abstraction or pure exercise in style, but a practical tool to analyze the dental anatomy, understanding the logic and hence manage the dynamics of stratification of the restorations. Only by knowing the optical and structural complexity of the tooth is possible to think of play, even partially, its characteristics in restorations.
The objective of this study is to highlight the correlations between optical phenomena and tooth structure and show that the photographic image is the ideal way to explore and understand these interactions.
