Detection of dental caries by using diffuse reflectance spectroscopy
Charvát, Jindřich ; Himmlová, Lucie (advisor) ; Suchánek, Jakub (referee) ; Bartoňová, Marie (referee)
Tooth decay is one of the most common infectious diseases. Its early detection is important to prevent the progression of the disease, and thus the emergence of a whole range of complications. Modern diagnostic methods such as laser fluorescence (DIAGNOdent) or transillumination (DIAGNOcam) are reliable in caries detection, especially in ex-vivo studies. However, they have their limitations in clinical use and are therefore only recommended as adjuncts and have not become widely used in practice. Diffuse reflection spectroscopy (DRS) is one of the methods of optical spectroscopy and is based on the principle of measuring the interaction of light with biological tissue. DRS is an experimental method for dentistry today. Currently, we are not aware of a study that would investigate the detection of dental caries using the DRS method in greater detail. This work deals with the possibilities of this method in the analysis of hard dental tissues and its use in the detection of dental caries. The study is divided into 5 parts: The first part deals with the capabilities of DRS to compare individual hard dental tissues. The second part deals with the ability to detect tooth surface demineralization caused by acids. The third part of the study is devoted to the differences in spectra between healthy and...
