Demographic data and exposure characteristics of the participants were obtained using a structured questionnaire. Buccal smears were obtained from both cheeks for each participant. The smears were stained using papanicolaou staining technique. At least 1000 cells in each smear were assessed and scored. The frequency of nuclear abnormalities in both road construction workers and control subjects was then compared.</p> <p><strong>Results: </strong>The results obtained show a significant increase in the frequency of CMN (p=0.005), TMN (p=0.008), and BN (p=0.006) in buccal cells of road construction workers compared with control subjects. Factors such as age, years in occupation, and work days per week, use of protective materials, on-going medication, smoking habit, and alcohol consumption did not significantly affect the frequency of nuclear abnormalities among the road construction workers.</p> <p><strong>Conclusion: </strong>Road construction workers may be exposed to substances capable of inducing nuclear damage in buccal cells.</p>}, number={4}, journal={Innovare Journal of Life Sciences}, author={ONWUKWE OKECHUKWU STEVEN and ACHUKWU PU and OKWUOSA CN and AZUBUIKE NC and ENIKE CE and ONYEMELUKWE AO and NNEDU EB and IKEGWUONU IC}, year={2019}, month={Jul.}, pages={1–4} }
