“…For the experimental paint sample, we could not record the Raman spectra because of strong luminescence, which was probably determined by a large amount of organic substance from lard that did not decompose over several decades. The pigment of the ancient paint from the Oxalate crusts are in general typical of the surfaces that are located under the open sky and are not subject to actions of atmospheric precipitates [5,6]. It was shown that oxalates can perform a stabilizing function, protect pigments against weathering, and reliably fix a paint on a substrate surface [6].…”

The results of a comparative analysis of the ancient paint layer of the Two-Eyed Stone (Dvuglazyi Kamen') pictograph (Alapaevsk, the Neyva River) and the experimental painting made at the same place in 1992 using paint prepared in accordance with the supposed ancient technology (grinding a piece of local iron ore with lard) are presented. The studies of mineral and chemical composition are carried out by SEM-EDS and Raman spectroscopy. The results do not preclude the use of local raw materials (hematite from iron ore occurrences of the "Alapaevsk" type) as a coloring pigment by ancient people. The technology of manual grinding of hematite-containing material, both in ancient times and today, has made it possible to obtain a finely dispersed pigment with almost submicron particle sizes. The ancient paint layer is covered with secondary formations, represented by crusts consisting of gypsum and weddellite crystals, in some cases with thin dolomite-magnesite interlayers on gypsum. Possible mechanisms for the gypsum crust formation are proposed. The formation of oxalate crusts (weddellite) may result from biological activity of lichens, whose probable traces are detected in the experimental painting. The traces of fat from domesticated ruminants, most likely ram, which could be added as a binder, in contrast to the experimental paint based on pig fat, were found in the organic component of the ancient paint. Both paint samples contain an admixture of organic substance of plant origin derived from the environment.

“…However, the main cause of pulp stones remains unknown [8], several factors have been recognized for their formation including aging [9] and idiopathic factors [10]. Other factors involved in this area include dental orthodontic movements [11], prolonged exposure to stimuli such as decay and deep fillings [12], surgical procedures and periodontal diseases [13].…”

A coronary artery disease is considered an important cause of mortality in society and imposed the extensive costs for patients. Therefore, the aim of this mini review was to evaluate the relationship between coronary arteriosclerosis and dental pulp calcification in patients. Dental radiography has the potential to be used as a rapid screening method for the early detection of coronary artery disease. Given the routine request for panoramic radiographs in dental examinations, dentists can use the technique to screen individuals with a risk of Cardiovascular Diseases (CVD). This shows the role of dentists in the general health of the public in society.
