Objectives: The aim of this study was to determine the prevalence of root filled teeth in a Sulaimani adult population.

Material and Methods:
Panoramic radiographs of 1015 patients were examined for the presence of endodontically treated teeth between April 2009 and October 2014. Two independent examiners discussed interpretation criteria and classified specimens according to the following data: presence of root canal treatment, which was defined as partially or completely filled canal space, regardless of whether filling ended at the radiographic apex or not; presence of intracanal post; and associated apical periodontitis.

Chi-square test and descriptive analysis were used for statistical analyses. Significance level was set at p<0.05. Of 24218 teeth evaluated, 4534 (18.7 %) were treated endodontically. Endodontic treatment was most frequent in mandibular molars, whereas mandibular incisors showed the lowest. Most endodontically treated teeth were found in people aged 18-29 years old. Females (54.29%) showed a higher prevalence of teeth with root fillings than males.

The present study found a higher prevalence of endodontically treated teeth in lower molars; females had more endodontically treated teeth than males.
