“…The differences in the Ba concentration in mineralized tissues of deciduous teeth have been defined by a statistically insignificant correlation coefficient (r=−0.39). The lowering of the level of elements' concentration, mainly trace elements (Cr, Cu, Pb, Cd) in deciduous teeth with increasing age of the surveyed children, was already observed in previous own studies [23] and other authors' study [24]. The results of literature research also show that the level of Ba in the body among children increases with the introduction of nutrients that complement breast-feeding [7].…”

The study determines the concentration of Ba in mineralized tissues of deciduous teeth, permanent impacted teeth, and facial bones. The study covers the population of children and adults (aged 6-78) living in an industrial area of Poland. Teeth were analyzed in whole, with no division into dentine and enamel. Facial bones and teeth were subjected to the following preparation: washing, drying, grinding in a porcelain mortar, sample weighing (about 0.2 g), and microwave mineralization with spectrally pure nitric acid. The aim of the study was to determinate the concentration of Ba in deciduous teeth, impacted permanent teeth, and facial bones. The concentration of barium in samples was determined over the ICP OES method. The Ba concentration in the tested bone tissues amounted to 2.2-15.5 μg/g (6.6 μg/g ± 3.9). The highest concentration of Ba was present in deciduous teeth (10.5 μg/g), followed by facial bones (5.2 μg/g), and impacted teeth (4.3 μg/g) (ANOVA Kruskal-Wallis rank test, p = 0.0002). In bone tissue and impacted teeth, Ba concentration increased with age. In deciduous teeth, the level of Ba decreased with children's age.

“…Byrne and Vrbic [25] determined a mean vanadium concentration of 3.7 ± 1.5 ng/g for 37 dental enamel samples of subjects from a low caries area of Dalmatia, Zemunik (DMFT < 2, decayed, missing, and filled teeth index), and a normal area, Novigrad (DMFT > 5); Derise and Ritchey [16] identified iodine values of 4.66 ± 0.62 and 4.05 ± 0.41 respectively in enamel and dentin of permanent teeth of children. The significantly higher level of Ba (10.5) was found in deciduous teeth than in the impacted teeth value of 4.3 in the population of children and adults (aged 6 -78) living in an industrial area of Poland and chromium (8.97 ± 11.94) and calcium of 20 ± 11.9 concentrations were found in the deciduous teeth of healthy children from Poland [24]. Tooth levels of 19 elements are compiled; considering their physiological roles at deficiency or excess status of essential, non-essential and toxic effects and the normal concentrations between deficiency and excess, the proposed reference values (ppm) are 10.0 (Pb), 1.0 ng/g (Hg), 0.05 (Cd), 0.05 (As), 100.0 (F), 0.…”

Reference values reflecting the findings of natural concentrations of teeth in a well-defined group of individuals, are indispensable, if one is to interpret results generated for clinical utility. Hence, a comprehensive compilation of literature survey is attempted to make available as a reference guideline for tooth element concentrations. Presently, the reference values are proposed for 19 elements. Several factors that are found influencing element levels, are common to any biosample and are broadly grouped under four categories namely, the factors of teeth, donor, environment and analytical methods. How best the influencing factors to be considered during analysis, are discussed. It is elucidated that standardized method of analysis with quality assurance and precision will reduce the ambiguity of comparison of inter-laboratory measurement. When the merits and demerits of element measurements are evaluated, it is recognized that except a hurdle of difficult specific sampling, many advantages make teeth an attractive material for environmental health monitoring of population and for assessment of element status of deficiency and excess due to differential exposure. The available data of tooth elements are lesser in comparison to data of blood and hair; further studies are required for reference values of others elements and for distribution pattern in different conditions, parts and types of teeth.

The knowledge of elemental composition of an archeological artifact is very helpful for archaeologists, physicists, and anthropologists in characterization of various aspects of past populations.…”

Laser-induced breakdown spectroscopy analysis of human deciduous teeth samples

et al. 2015

Laser-induced breakdown spectroscopy (LIBS) analysis of human deciduous teeth has been performed by employing Nd:YAG laser (1064 nm, 10 ns) for the evaluation of plasma parameters as well as elemental analysis. The plasma parameters, i.e., electron temperature and electron number density of laser-induced teeth plasma at various fluencies, have been evaluated. Both parameters show an increasing trend up to a certain value of laser fluence, i.e., 2.6 J/cm(2). With further increase in laser fluence up to a value of 3.9 J/cm(2), a decreasing trend is observed which is due to shielding effect. With further increase in laser fluence up to a maximum value of 10.5 J/cm(2), the insignificant changes in plasma parameters are observed which are attributed to saturation phenomenon governed by self-regulating regime. Emission spectroscopy results exhibit that laser fluence is the controlling factor for both plasma parameters. The elemental analysis was also performed at constant laser fluence of 2.6 J/cm(2) by evaluating the variation in detected elemental concentration of Ca, Fe, Sr, Zn, and Pb in three different parts of human teeth, i.e., enamel, dentine, and cementum. The lower concentration of Ca as compared to the standard values of CaCO3 (self-fabricated pellet) reveals that enamel is the most deciduous part of the human teeth. However, at the same time, it is also observed that the highest concentration of micro minerals is also found in enamel, then in dentine, and lowest in cementum. Carious or unhealthy tooth is identified by enhanced concentration of micro minerals (Pb, Sr, Zn, and Fe). The highest concentration of micro minerals as compared to other parts of teeth (dentine and root cementum) and lower concentration of Ca as compared to standard CaCO3 pellet in enamel confirm that enamel is the most deciduous part of the teeth.
