Finally, the data were analyzed using SPSS18 software, Chi-square and Fisher exact test. Results: In the present research, the prevalence of irreversible pulpitis was obtained to be 77%. This prevalence in female was significantly more than males (P-value = 0.021). Patients with irreversible pulpit significantly reported more severe pain (p-value=0.000) and pain at the real site (p-value=0.028).The frequency of irreversible pulpitis showed no significant correlation with age and type of pain (P-value<0.05). Conclusion: Considering the findings of this research, the prevalence of irreversible pulpitis in patients refferd to Endodontic department of dental school of shahid Sadoughi University in 2017 with chief complaint of pain was three times more than that of other diseases.
