Purpose of investigation: To assess the frequency of oral cytological abnormalities in women who have cervical intraepithelial lesions, and transmission of infection depending on their sexual behavior. The authors also aimed to investigate the oral cytological changes in male partners. Material and Methods: Thirty patients with abnormal cervical cytological results via punch biopsy formed the case group, and 68 patients constituted the control group with normal cervical smear results. The Bethesda system was used for classification of the cytological alterations. Results: Oral dysplasia was significantly higher in the squamous intraepithelial lesion (SIL) group. Oral sex percentage was 43.3% in SIL group, whereas it was 19.1% in the control group. History of genital warts in women with SIL was also significantly higher in the case group. Three patients were diagnosed with abnormal oral cytology in the SIL group (10%), however abnormal oral cytology was not detected in the control group. No oral dysplastic changes was identified in the male partners of women with oral lesions. Conclusion: The authors detected oral dysplastic changes in the SIL group, especially in the (low grade squamous intraepithelial lesion (LGSIL) patients. Interestingly they could not find any oral dysplastic changes in the male partners of the study population.
