“…Similar conclusions were reached by a study in Finland [41]. In contrast, lead [14] [42] and Mn [43] concentrations were significantly higher in males than in females. Thus, both no significance and significance in element levels were observed due to genders.…”

“…The average dentin fluoride concentrations per exfoliated primary tooth were 792 ± 402 for incisors and 768 ± 489 for molars of children from North Carolina [19]. Higher fluorine content was indentified in the healthy teeth (304.8) than in the teeth with decay (235.6) [20], while low levels 87.9 ± 8.5 (enamel) and 133.5 ± 19.1 (dentin) were found in permanent teeth of 10 -12 year old subjects from Virginia [14].…”

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.

“…Because they are not as extensively metabolised as bone tissue [ 25 ], they constitute a reservoir of heavy metal ions, whose concentration informs us about the effects of long-term exposure to harmful elements in the context of health risk assessment. It is assumed that the level of metals observed in tissues of teeth correlates with their presence in the bloodstream, especially in the context of long-term exposure [ 26 ]. Deciduous teeth, which are lost naturally, constitute relatively easily accessible material for analysis.…”

Objectives. The aim of the study was an assessment of the content of trace elements in enamel and dentin of teeth extracted in patients residing in urban and agricultural areas of Poland. Methods. The study included 30 generally healthy patients with retained third molars. 65 samples of enamel and dentin from individuals living in urban areas and 85 samples of enamel and dentin from individuals living in agricultural areas were prepared. The content of manganese, lead, cadmium, and chromium in the studied enamel and dentin samples from retained teeth was determined by Graphite Furnace Atomic Absorption Spectrometry. In the process of statistical hypothesis testing, the level of significance was assumed at α = 0.05. Results. A comparative analysis of the data showed that enamel and dentin of inhabitants of industrialized areas contain significantly higher amounts of lead and cadmium than hard tissues of teeth in residents of agricultural areas and comparable amounts of manganese and chromium. Significance. It appears that hard tissues of retained teeth may constitute valuable material for assessment of long-term environmental exposure to metal ions. The study confirms that the risk of exposure to heavy metals depends on the place of residence and environmental pollution.
