FEATURES OF AGE DYNAMICS OF CALCIUM AND STRONTIUM CONTENT IN BONE LOWER JAW OF PRESCHOOLERS
Journal Title: Праці Наукового товариства ім. Шевченка - Year 2016, Vol 45, Issue
Abstract
Introduction. The degree of mineralization of bone tissue depends on the macro elements content in it and on the course of metabolic processes in the body, which are the catalysts of microelements. The purpose of our work was to investigate the characteristics of calcium and strontium content in bone tissue of the lower jaw of collar part, their relationship and age dynamics in preschool children. Material and methods. To achieve this goal were conducted atomic absorption spectral analysis of 70 fragments of bone tissue of collar apophysis mandible of the lower jaw in children under 6 years (post extraction material and material obtained during surgery on the injury of lower jaw), obtained in pediatric wards of dental clinics of Lviv. All material was divided into 5 age groups - up to 6 months, to 1 year, to 2 years, to 4 years and 6 years, 7 fragments in each group (boys and girls, respectively). In the investigated fragments of bone tissue the content of calcium (Ca) and strontium (Sr) were determined. Research was carried out on atomic absorption spectrophotometer C-115, the concentration of the search elements in samples of bone tissue were indicated in mg/g. Results. Conducted atomic absorption spectral analysis collar of bone tissue of the lower jaw in children of different sexes of preschool age allowed to determine the content of calcium and strontium. It was set up that regardless of gender, the content of calcium in bone tissue of the jaw in children is gradually increasing to 4 years of age and slightly reduced to 6 years. Minimum indices of calcium content is in the 6-month, and the maximum - in 4 years. Herewith in all age groups the absolute levels of calcium in bone tissue are higher in girls than in boys. The content of strontium also has a similar age dynamics of boys and girls. Indicators strontium content increases in children 1 year of age, compared with a 6-month, slightly lower in the 2-years, sharply increasing (more than into 2 times) in the 4-years and continue to rise to 6 years. It was established that during the investigated age interval, the minimum content of strontium is 2 years of age, and a maximum at 6 years. In contrast to calcium, strontium content indexes in bone tissue of mandible in boys are higher than in girls exception in children 2 and 4 years of age, where the difference in terms of the two sexes were not found. Conclusions. This age dynamics of calcium and strontium content provides a balance of resorption and aposition processes in the bone tissue of the lower jaw in preschool children and with the result that an intensive and well-coordinated restructuring of the jaws associated with the development of dental germs of both generations, and functioning eruption of primary teeth that must be considered when planning dental treatment for children in this age group.
