The number of micronuclei in buccal cells was significantly higher in females than in males. There was positive association between the age and frequency of analysed cytogenetic biomarkers. Buccal cell micronuclei and degenerative nuclear alternations were more frequent among cigarette smokers than non-smokers and significantly higher in female smokers than in male smokers. Cytogenetic damages showed significantly positive correlation between intensity of smoking and the number of nuclear alterations. The years of smoking had a significant influence not only on the number of nuclear alterations but also in micronuclei and nuclear buds in buccal cells.<br /><strong>Conclusions:</strong> The sex influences the number of micronuclei in human buccal cells. The ageing increased the number of micronuclei and other biomarkers of DNA damage. The cigarette smoking significantly increases the frequencies of micronuclei and nuclear buds, pyknotic, karyolytic and karyorrhectic cells.}, number={3}, journal={Journal of Health Sciences}, author={Nefić, Hilada and Mušanović, Jasmin and Kurteshi, Kemajl and Prutina, Enida and Turcalo, Elvira}, year={2013}, month={Dec.}, pages={196–204} }
