Abstract Background and Objective: Haller's cells eponymously known as maxillo-ethmoidal or orbito-ethmoidal or infra-orbital ethmoid cells refer to pneumatisation of ethmoid air cells in the superior aspect of the maxillary sinus and floor of orbit. Panoramic radiographs may serve as an important and effective tool to determine the presence of Haller's cells. The clinical importance of these anatomic variations and lack of knowledge among dental professional about the same initiated the need for this study with the aim to determine the prevalence and characteristics of Haller's cells on digital panoramic radiographs in Moradabad population. Material and Methodology: This retrospective study compromised of 200 randomly selected panoramic radiographs of patients in the age group of 18–60 years. Haller's cells were identified according to the criteria suggested by Ahmad et al. The data collected was tabulated and subjected to descriptive statistics and chi-square analysis. Results: Haller's cells were observed in 7% of the 200 radiographs. Most of the Haller's cells were unilateral (92.8%). Maximum cells were oval in shape, unilocular and single in number. Conclusion: In the present study, it was found that the presence of Haller's cells can be very well appreciated on panoramic radiographs. Though an anatomic variations of the ethmoid sinuses, Haller's cells may account for distressing patient symptoms and conditions. The ability to identify these cells on routine panoramic radiographs may thus help in differential diagnosis of orofacial pain.
