The Study of Barium Concentration in Deciduous Teeth, Impacted Teeth, and Facial Bones of Polish Residents

Abstract

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.

Urban and rural area differences in the interaction between oxidative process elements in human femoral bone

“…In the case of facial bone, the level of Ba increased with the age of the subjects. Ba increased with age in bone and teeth (Fischer et al 2014). In our study, Ba content decreased with age most statistically significantly in the FH of rural residents.…”

Effects of Bacillus subtilis on Production Performance, Bone Physiological Property, and Hematology Indexes in Laying Hens

“…The ash was dissolved with nitric acid and diluted up to 50 mL with ultra-pure water. The contents of Ca, P, and Mg were analyzed using an inductively coupled plasma-optical emission spectrometer (ICP-OES) (iCAP 7000 SERIES, Thermo, Waltham, MA, USA) [39][40][41].…”

Adsorption of Ba2+ ions at the hydroxyapatite/NaCl solution interface

“…Moreover, this process was considered to remove barium from water (Suzuki et al 1981). It is commonly known that barium can replace calcium in bone and teeth (Boanini et al 2010;Fischer et al 2014). Most of the barium doped hydroxyapatite studies were carried on the samples prepared using the precipitation method and the adsorption of only barium ions was studied by Suzuki et al(Suzuki et al 1981).…”
