Abstract
Introduction: Pregnancy tumor that is the same as pyogenic granuloma from histological aspect is a hemorrhagic reactive nodule which mostly appears in gingival area in pregnancy and can cause secondary oral infections. Due to the high prevalence of this lesion in pregnant women and lack of solid status in Iran, this project was carried out to study the prevalence of pregnancy tumor and related factors.

Sampling was made by sequential method. Data were analyzed using chi-square test.
Results: 72 of 1600 patients with average age of 26.8 years old (4.5%) had pregnancy tumor. In 66 cases, lesions were found in maxillay gingiva and in 6 cases were found in mandibular gingiva. Poor oral hygiene were found in 58 women (80.6%) and 50 women (69.4%) with the lesion were in the last trimester of pregnancy.
