In the study, digital panoramic x-rays of the patients will be evaluated and dental age estimation with Willems method and mandibular bone morphometric measurements will be made.

The study group will be comprised of newly diagnosed pediatric patients who applied to Umraniye Training and Research Hospital Division of Pediatric Rheumatology and whose treatment is ongoing, and the control group will be composed of pediatric patients without systemic disease who applied to Marmara University Faculty of Dentistry Department of Pedodontics.

A region of interest will be selected from panoramic radiographs. Image processing will be applied to correct for lightning irregularity, and box-counting method will be used to calculate a fractal dimension.
