Background and Aim: Cervical smears contain endocervical cells which are accepted as representatives for cytological diagnosis. The purpose of this study was to compare the adequacy of cervical cytology sampling and endocervical cells together; using two sampling instruments, namely Cervix Brush and Ayres Spatula. Materials and Method: In a randomized controlled clinical trial, Pap smears of 184 women referring to family planning and health center were obtained by means of Ayres Spatula (95 cases), and Cervix Brush (89cases). The cases were randomly chosen from the total population for Cervix Brush or Ayres Spatula cytology sampling. The pathologist, however, was unaware of the kind of device used for each smear. The pathologist interpreted Pap smear quality, endocervical and transduction zone count, bleeding cell count; and squamous cell count .Besides, cell changes were measured according to Betsa system. Finally, the obtained data was analysed through Fisher, Chi-square, and T-test at the significant level P≤0.05. Results: The quality of cells present in the smears was alike in both groups. In Cervix Brush group endocervical cells were found in 91% of the cases, and metaplastic cells in 19.1% but 78.9% and 13.7% of spatula samples were endocervical and metaplastic respectively. Thus, the difference between the two groups was significant (P<0.02). Less patients (8.5%) in cervix brush and more (22.2%) in spatula group reported discomfort. There was a significant difference between the two methods (cervix brush and spatula ayres) regarding ease of application and extent of pain (P=0.01). Conclusion: On the basis of the findings of the study Cervix Brush is superior to Ayres Spatula in obtaining endocervical smears.
