Background & Objectives: cervical dysplasia indicates the growth disorder of cervix and is characterized by the appearance of cancerous and precancerous cells in cervix. Cervical dysplasia often has no symptoms but can progress to cervical cancer in 5 % of the cases. Early diagnosis of these pre-invasive lesions with pap smear can prevent, to a great extent, the progress of lesion to cancer. The prevalence of cervical dysplasia is different in different parts of the world and depents, to a great extent, on its etiology. This study was an attempt to determine the prevalence and types of cervical dysplasia in 5000 cases of pap smears.

 Methods: This descriptive cross-sectional study was conducted on 5000 cases of pap smears selected randomly from among 8249 pap smears in the period between March 2003 to August 2004. Some samples were studied retrospectively and some others prospectively. The population of the study was composed of women referring to Ardabil health care centers for pop smear test. The data were collected with questionnaires and were analyzed using SPSS software (ver.11).

 Results: Cervical dysplasia was found in 56 cases (1.12%) 0.66% of which was CIN I, 0.3% CIN II and 0.16% CIN III.

 Conclusion: The total percentage of cervical displasia in this study was 1.12%. This prevalence in other similar studies varies between 0.4% in Scotland and 12% in USA. Nevertheless, the prevalence found in this study is in line with most of the similar researches.

  Background & Objective: As cancer of cervix is one of the important facts, for women and probably causes in presence, furthermore early diagnosis and management in primary stages is very effective for prognosis of the disease and survival, the aim of the study was to measure the probable relationship of contraraceptive devices with cervical lesions.

 Methods: This study was a descriptive analytic study that was done by referring to all pathologic center (6 centers) in Ardabil and reviewing 399 reports of pap smear through sampling method (one of them because of chemotherapy was excluded from the samples)

 Results: In this study 90 persons 22.5% of pop smear’s study were normal and 309 persons 77.5% were abnormal that include nonspecific cervicitis (298 persons) specific cervicitis (192 persons) and epithelial cell abnormality (105 persons) Regarding the use of contraceptive devices, 15 persons didn't use any device 3.8% And 172 persons 43% were using one of the natural methods or tubal ligation, and 131 persons were using OCP pills 32.9% 63 persons were using IUD 15.8% 18 persons 4.5% were using condom, and also DMPA was not used. Through chi test it was found that there was significant relationship between contraceptive methods and epithelial cell abnormality (p=0.008) and imperavite cervicitis (p=0.001). There was a meaningful relationship.

 Conclusion: There was a meaningful relationship between using contraceptive methods and nonspecific cervicitis.
