The aim of the study was to interpret the usefulness of fractal analysis of the trabecular bone of the mandible (FD) and selected radiomorphic indices (the antegonial index (AI) and Klemetti index (KI)) to assess the risk of reduced bone mineral density (BMD) in patients with hemophilia A\/B. Methods: The study group consisted of 50 patients with type A\/B hemophilia. The control group consisted of 25 males without congenital bleeding disorders. The patients had a panoramic radiograph taken with the same X-ray machine (Vistapano S, Durr Dental, Bietigheim-Bissingen, Germany). The AudaXCeph software (Audax d.o.o., Ljubljana, Slovenia) was used to evaluate the AI index, and the ImageJ, software with a specially prepared script, was used to evaluate the FD. The mandibular cortex was assessed distal to the mental foramen using the Klemetti index. Results: There were no statistically significant differences between the AI, KI and FD values between the study group and the control group. Conclusions: This study indicated the lack of usefulness of AI, KI and fractal analysis in identifying patients with hemophilia at risk of reduced bone mass.<\/jats:p>","DOI":"10.3390\/jcm12216901","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T09:28:13Z","timestamp":1698917293000},"page":"6901","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Panoramic X-ray as a Supportive Diagnostic Tool for the Screening of Osteoporosis in Patients with Hemophilia A and B"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3967-9586","authenticated-orcid":false,"given":"Sylwia","family":"Czajkowska","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Rupa-Matysek","sequence":"additional","affiliation":[{"name":"Department of Hematology and Bone Marrow Transplantation, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5042-5985","authenticated-orcid":false,"given":"Kacper","family":"Nijakowski","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lidia","family":"Gil","sequence":"additional","affiliation":[{"name":"Department of Hematology and Bone Marrow Transplantation, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9952-0230","authenticated-orcid":false,"given":"Anna","family":"Surdacka","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0312-619X","authenticated-orcid":false,"given":"Tomasz","family":"Kulczyk","sequence":"additional","affiliation":[{"name":"Department of Diagnostics, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1016\/S0140-6736(15)01123-X","article-title":"The Past and Future of Haemophilia: Diagnosis, Treatments, and Its Complications","volume":"388","author":"Peyvandi","year":"2016","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1111\/j.1365-2516.2006.01405.x","article-title":"Osteoporosis in Haemophilia\u2014An Underestimated Comorbidity?","volume":"13","author":"Wallny","year":"2007","journal-title":"Haemophilia"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1111\/j.1756-185X.2009.01394.x","article-title":"Reduced Bone Density in Individuals with Severe Hemophilia B","volume":"11","author":"Mansouritorghabeh","year":"2009","journal-title":"J.
