Background and Aims: In the panoramic images, palatoglossal space error develops when the patient is unable to put the tongue against the mouth roof. In the case of this error, the radiographic diagnosis of the area is made with some difficulties or ever the image may lose its diagnostic ability. The aim of the present study was to investigate the relationship between the palatoglossal space error of the panoramic images and skeletal relationship.
Materials and Methods: In this descriptive cross-sectional trial, 494 panoramic images were selected at the orthodontic department of Tehran dental school archive and the existence of the palatoglossal space was determined. The palatoglossal space error was statistically analyzed using chi-square test regarding the patients’ gender, age and skeletal relationships.
Results: Of total panoramic images, 346 (70.0%) cases showed palatoglossal space error while 148 (30.0%) images were free from this error. Furthermore, 74.1% of male images and 66.9% of female images showed palatoglossal space error. In Cl I (1˂ANB≤3), Cl II and Cl III patients 65.6%, 73.1% and 67.4% of the images demonstrated the error, respectively. The incidence of palatoglossal space error in 5-14 and 15 years old age or higher patients were 72.2% and 58.8%, respectively.
Conclusion: It was concluded that n o significant difference w as noted between the incidences of the palatoglossal space error regarding the patients’ gender or their skeletal relationships . T he error frequency was significantly decreased with age .
