Title: Evaluation of Haller&rsquo;s Cell in Panoramic Radiography in Selected Iranian Population. Background and purpose: The purpose of this study was to evaluate Haller cells in panoramic radiography in Iranian population. Examining the Haller cells in this radiography can be helpful in the differential diagnosis of Orofacial Pain. &nbsp;Materials and Methods: This was a descriptive cross-sectional study. 300 panoramic radiographyes were selected including 151 women and 149 men, that they were 18-68 years old. Radiographies were studied by Ahmad et al. Data were analyzed using version 17 of the SPSS software and the Fisher test. Results: The highest number of Haller cells (%33.33) was founded in the age group of 18- 28 years. The most common form was oval (%45/16) and the least, was cardiac (%1.5). The relationship between the shape and number of Haller cells was significant (P-value <0.001). The prevalence of single Haller cells was (%76.66) more than multiple cells (%23.33). The relationship between the shape and position were significant in Haller cells (P-value = 0.036). Most of the Haller cells were on the left side (%43.66) and the least were bilateral (%15.83).&nbsp; There were no significant relationship between the shape of the Haller cells and gender (P-value = 0.3), and no presence or absence of cavity were found between the shape of the Haller cells (P-value=%13). Conclusion: Haller cells have almost the same prevalence in both genders. The most common form of Haller cells was oval and one-sided, and left-handed. There was no significant difference in the existence of cavity in Haller cells. &nbsp;
