“…Strontium was supposed to have a cariostatic effect if administered prenatal compared to post-natal, as demonstrated in rodents [9]. In carious teeth the concentration of strontium was significantly lower when compared to intact teeth [10][11]. Blood concentration of strontium, phosphate and fluorine was significantly lower in patients with high carious activity in comparison with patients with low carious activity [12].…”

Objectives: To analyze the ion exchange between conventional glass-ionomer restorative material, (Fuji IX-GC Co., Japan) and tooth components in primary molars after long periods of function in vivo. Methods: Five deciduous mandibular molars were collected after normal exfoliation. An intact deciduous molar served as control, a second deciduous molar was restored occlusaly with Fuji IX in vitro, and 3 deciduous molars with occlusal restorations were collected after 18, 24, and 48 months in vivo. The molars were sectioned bucco-lingual through the restoration and the chemical analysis was performed on enamel, dentin and restorative material along parallel lines crossing from buccal to lingual, using an energy dispersive X-ray spectrometer (EDS). The data was analyzed using SPSS program. Results: In the enamel adjacent to the glass-ionomer material, calcium and phosphate showed a significant reduction related to time (P<0.05). In both enamel and dentin strontium, silica and alumina migrated from the glass-ionomer material in significant concentrations (P<0.05), and fluorine showed an increase from zero in the intact deciduous molar to 1.2% after four years in vivo. In the glass-ionomer material fluorine was reduced in relation with time in vivo, while calcium concentration increased. Conclusions: There is a constant exchange of ions between glass-ionomer restorative material and tooth components in deciduous molars. It begins as early as two weeks in vitro and is increased in vivo. Strontium, alumina and fluorine released from the glassionomer have a bactericidal effect and may affect remineralization. Calcium may enhance the glass-ionomer mineralization and transform it into enamel like material. Clinical significance: The results showed that a continuous exchange of ions between enamel and dentin and glass-ionomer material occurs in vivo and the concentration of the ions is time related. Strontium, alumina and fluorine in enamel and dentin may cause a continuous anti bacterial and anti cariogenic effect, while calcium enhance mineralization of glass-ionomer in vivo, a factor that may increase the longevity of the restoration.

“…Table 1 shows significantly high boron in blood of carious persons. This element was also high in carious teeth in our recent study [4]. Boron occurs in very large concentrations in ocean, rocks, and soil and is also present in plants and water [7].…”

“…This is supported by our recently published study in which we had found that, out of 35 elements analyzed, strontium was the only element found to be present in significantly lower amount in carious teeth. The mean strontium content of carious teeth was 238 ppm as opposed to 389 ppm in non-carious sound teeth [4]. The experimental proof of beneficial effect of strontium in preventing calcium loss from teeth is provided by our recent study in which we had found that strontium pre-treatment of both carious as well as sound teeth resulted in a significant decrease in calcium released from them when immersed in 1% lactic acid [15].…”

“…However, no such reports are published about any relation between chemical composition of a person's blood and dental caries. In our earlier study, we examined 35 inorganic elements in non-carious and carious teeth and found that strontium was significantly lower in carious teeth [4]. This study also pointed towards relation between excess of certain elements in carious teeth (B, Mn, Mo, and F) and caries.…”

In order to determine any possible relation between chemical composition of a person's blood to formation of dental caries, whole blood was analyzed for 35 inorganic elements (Si, Al, Fe, Ca, Mg, K, Mn, Ti, P, Li, Be, B, V, Cr, Co, Ni, Cu, Zn, As, Sr, Y, Nb, Mo, Ag, Cd, Sn, Sb, Ba, La, Ce, W, Pb, Bi, Zr, and F) in the 15 people having sound teeth as well as an equal number of those having multiple caries. The results showed the absence of 13 elements (Si, Al, Mn, Ti, Be, Co, As, Y, Cd, Ba, La, Ce, and Zr) in the blood of both groups. Of the remaining 22 elements, the results of only seven elements (Fe, P, B, V, Sr, Sn, and F) were significantly different between the two groups. The most remarkable finding of this study was significantly decreased amount of phosphorus, strontium, and fluorine and perhaps increased boron in the blood of persons with caries.

“…A series of papers contained arguments for relation between heavy metal content and the number of carries of patients, but according to literature data [1,4,5] it is difficult to have a clear conclusion in this moment [7][8][9]. First of all the number of carries as an expression of oral health could be the result of many other social factors, and despite the fact that the environment quality is a part of quality of life, it is very difficult to be sure that the teeth are collected from a target group with similar life conditions.…”

Abstract-The paper aims the evaluation and discussion of behavior of natural temporary teeth from groups of children living in regions with various pollution areas regarding the level of heavy metals. The small amounts of very aggressive metals such as Cd and Pb detected in the groups of teeth by using an ELAN DRC-e induced plasma coupled spectrophotometer (ICP-MS) have been correlated with surface aspects discussed based on confocal microscopy and wettability. The correlations sustain the idea that the teeth from high pollution areas exhibit higher roughness and many holes, being in fact more degraded. A statistical treatment according to ANOVA test completed this study.Index Terms-temporary teeth, heavy metals, surface analysis, ICP-MS, confocal microscopy.
