【 摘 要 】

Bacground/Aim. Environmental lead (Pb) pollution is a global problem. Harddental tissue is capable of accumulating lead and other hard metals from theenvironment. The aim of this study was to investigate any correlation betweenthe concentration of lead in teeth extracted from inhabitants of Pančevo andBelgrade, Serbia, belonging to different age groups and occurrence of toothloss, caries and non-carious lesions. Methods. A total of 160 volunteers werechosen consecutively from Pančevo (the experimental group) and Belgrade (thecontrol group) and divided into 5 age subgroups of 32 subjects each. Clinicalexamination consisted of caries and hard dental tissue diagnostics. TheDecayed Missing Filled Teeth (DMFT) Index and Significant Caries Index werecalculated. Extracted teeth were freed of any organic residue by UV digestionand subjected to voltammetric analysis for the content of lead. Results. Theaverage DMFT scores in Pančevo (20.41) were higher than in Belgrade (16.52);in the patients aged 31-40 and 41-50 years the difference was significant (p< 0.05) and highly significant in the patients aged 51-60 (23.69 vs 18.5, p <0.01). Non-carious lesions were diagnosed in 71 (44%) patients from Pančevoand 39 (24%) patients from Belgrade. The concentrations of Pb in extractedteeth in all the groups from Pančevo were statistically significantly (p <0.05) higher than in all the groups from Belgrade. In the patients fromPančevo correlations between Pb concentration in extracted teeth and thenumber of extracted teeth, the number of carious lesions and the number ofnon-carious lesions showed a statistical significance (p < 0.001, p < 0.01and p < 0.001, respectively). Conclusion. According to correlations betweenlead concentration and the number of extracted teeth, number of cariouslesions and non-carious lesions found in the patients living in Pančevo, onepossible cause of tooth loss and hard dental tissue damage could be along-term environmental exposure to lead.
