“…It is caused by precipitation of minerals from saliva and gingival crevicular fluid in plaque on the teeth. There are about 1,000 out of the 25,000 species of bacteria that are involved with the formation of dental plaque, but microorganisms that form the plaque are mainly Streptococcus mutans and anaerobes, with the composition varying by location in the mouth [10]. It has long been recognized that the bacteria Streptococcus mutans produces special metabolites called porphyrins.…”

“…This device has shown good results in the detection of occlusal caries, however, it might not be used as the only method for treatment decision-making process [7]. The other investigators have shown that under UVA light (near ultraviolet) sound teeth emit blue -green color, while caries teeth emit the red fluorescence [8][9][10][11][12][13][14]. Based on the difference in the color of the teeth fluorescence caries lesions can be detected.…”

Dental caries is a major oral health problem in most industrialised countries and is still a major cause of tooth loss. The early diagnostics of caries is of great importance for children and adults to facilitate the treatment and prevention of the diseases. In this study, a fluorescence camera was designed and manufactured for this purpose. This device includes a 380-nm LED, which stimulates porphyrins - metabolic products of the life cycle of caries-inducing bacteria to emit fluorescence, and a compact camera recording fluorescence images in real time. The device is connected to computer via usb cable. An archiving software helps save shots as image or video. The weight and size of this device are suitable for the visual inspection in oral cavity and can be used in daily dental practice. The test results showed that this fluorescence camera can detect some types of carious lesions including dental plaque, dental caries, hidden caries and early caries. Besides, this tool has a number of advantages such as noninvasiveness, safety (non-ionizing radiation), mobility, rapid test time, and economical.

In view of its potential for biological tissues analyses at a molecular level, Raman spectroscopy in optical range has been the object of biomedical research for the last years. The main aim of this work is the development of Raman spectroscopy for organic content identifying and determination of biomarkers of saliva at a molecular level for periodontitis diagnostics. Four spectral regions were determined: 1155 and 1525 cm −1 , 1033 and 1611 cm −1 , which can be used as biomarkers of this widespread disease.An informative volume deposition on the dried saliva drop (50× magnifications)
