    Malocclusion can affect the stomatognathic system and induce changes in bone density that can be evaluated through a panoramic radiograph. The aim of this study was to determine bone density based on Angle’s malocclusion classification on female patients aged 13-30 years old on panoramic radiograph. In the current study, ninety digital panoramic radiographs of female patients aged 13-30 years old with 30 radiographs representing each of the Angle’s malocclusion classes (class I, class II, class III) were used. Bone density was measured by using ImageJ software with 20x20 pixels intensity by using a method based on the mental index (MI). The result of the current study revealed that the mean bone density of female patients aged 13-30 years old with Angle’s malocclusion of class I was 18.726% of cortical and 81.274% of marrow, class II was 16.804% of cortical and 83.196% of marrow, and class III was 15.911% of cortical and 84.089% of marrow. In conclusion, the bone density of female patients aged 13-30 years old with Angle’s class I malocclusion was higher than class II, and class II malocclusion has higher bone density than class III on panoramic radiograph.
