A full set of records were taken including photos and intraoral scan. Finally, existing cone beam computed tomography (CBCT) images and radiographs were also studied.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All patients presented with bimaxillary micrognathia, five had a convex profile, and two had a straight profile. In addition, posterior open bite, Angle Class III molar relation with accompanying anterior crossbite and a grooved median palate were common findings. No patient showed symptoms of temporomandibular disorder (TMD) apart from some clicking. Finally, the main radiographic findings were the obtuse mandibular angle, the frontal bossing, the elongation of the coronoid\/condylar process and the presence of hypercementosis with obliterated pulp chambers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The examined patients with PDO were characterized by dental crowding, malocclusion (anterior crossbite, posterior open bite), hypercementosis, obliterated pulp chambers and deviations in mandibular morphology. In conclusion, patients with PDO have a specific need for dental and orthodontic monitoring with focus on crowding and posterior open bite. The patients will benefit from a long\u2010term orthodontic plan including extractions.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ocr.12782","type":"journal-article","created":{"date-parts":[[2024,3,27]],"date-time":"2024-03-27T06:49:27Z","timestamp":1711522167000},"page":"656-664","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Pycnodysostosis: Characteristics of teeth, mouth and jaws"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4995-1934","authenticated-orcid":false,"given":"Nikolaos","family":"Ferlias","sequence":"first","affiliation":[{"name":"Department of Dentistry and Oral Health, Section of Orthodontics Aarhus University  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Gj\u00f8rup","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Center for Oral Health in Rare Diseases Aarhus University Hospital  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia Aagaard","family":"Doherty","sequence":"additional","affiliation":[{"name":"Childhood Cancer Research Group Danish Cancer Research Institute  Copenhagen Denmark"},{"name":"Department of Pediatrics and Adolescent Medicine Aarhus University Hospital  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Klit","family":"Pedersen","sequence":"additional","affiliation":[{"name":"Department of Dentistry and Oral Health, Section of Orthodontics Aarhus University  Aarhus Denmark"},{"name":"Department of Oral and Maxillofacial Surgery Aarhus University Hospital  Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,26]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.36557"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/ocr.12479"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5200481"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tripleo.2007.05.011"},{"key":"e_1_2_11_6_1","unstructured":"Orpha.net.2019.https:\/\/www.orpha.net\/consor\/cgi\u2010bin\/index.php.
