Objectives: Evaluation of influence the structural and functional condition of bone tissue on caries intensity in adolescents living with deficient of fluoride in drinking water (<0.4 mg/l).

Methods: It was examined 200 school children (12 and 15 years old) living in Transcarpathian region.

Oral examination was done to determine caries intensity in the subjects (DMFT-index). Bone quality was determined using quantitative ultrasound densitometry and included the following parameters: speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index (SI), and bone mineral density (BMD) index.

The data were acquired, computed and statistically analyzed to compare the correlation between the sources of bone mineral density and caries intensity.

Results: The studies had found statistically significant increase of DMFT index with age in children of both sexes: in girls in 12 it was 5,0 (4.0; 10.0), in 15–10.0 (7.0; 13.0) and in boys–6.0 (4.0; 7.0) and 10.0 (6.5; 12.0) respectively (P<0.001).

By studying the characteristics of ultrasonic bone mineral density identified the following patterns: 12-year olds girls compared with boys had higher values of SOS–1559.2 (1545.8; 1572.3) to 1546.5 (1538.4; 1557.6), P<0.005; SI–94.39 (86.68; 100.5) to 89.22 (82.99; 96.93), P<0,05; BMD index – 0.52 (0.47; 0.56) to 0.49 (0.45; 0.54), P<0.05 and in 15-year-old girls–indicators of SI 95.17 (87.3; 101.48) to 90.15 (81.9; 100.01), P<0.05; BMD index – 0.52 (0.47; 0.56) to 0.49 (0.44; 0.56), P<0.05.

Low bone mass was observed in 2.27% (95% CI: 3.95; 19.58) 12-year-old girls and 9.09% (95% CI: 3.95; 19.58) 12-year-old boys; among 15-year-old children–in girls: 3.64% (95% CI: 0.44, 13.14) and in boys: 13.64% (95% CI: 6.4; 26.71).

It was found statistically significant negative correlation in 12 years girls between caries intensity and SOS (Spearman correlation coefficient (R), R=−0.47; P<0.01), BUA (R=−0.39; P<0.005), SI (R=−0.47; P<0.005), and BMD (R=−0.47; P<0.005). Also in 15-year-old children found moderate negative correlation between DMFT and SOS: in girls (R=−0.25, P<0.05), in boys (R=−0.34, P<0.05).

Conclusion: Low bone mineral density can be considered as one of the important factor to increase the caries intensity.
