Chulalongkorn Medical Journal

Introduction:

Pyle's disease, also known as familial metaphyseal dysplasia, is a rare autosomal recessive genetic disorder that primarily affects the skeletal system, particularly in children and adolescents. Characterized by distinctive radiographic features such as Erlenmeyer flask deformity and metaphyseal widening, Pyle's disease often goes underdiagnosed due to its mild clinical manifestations.

Case report:

This case report details a 15-year-old female patient presenting with retained milk teeth and unerupted permanent teeth, alongside notable skeletal abnormalities including genu valgum and kyphosis. Clinical and radiographic evaluations revealed significant dental anomalies, including multiple impacted permanent teeth and mild dysmorphic facial features. Although genetic testing …

Comparison Of Pharyngeal Airway And Dentoskeletal Effects Of 2 And 4 Premolar Extraction Treatment In Adult Orthodontic Patients, Esra Genc, Ahmet Karaman

Journal of Dentistry Indonesia

Objective: This study aimed to compare pharyngeal airway and dentoskeletal effects of 2 and 4 premolar extraction treatments in adult patients separately for each gender. Methods: The study was conducted with 60 adults (26 males; 34 females) aged 18-35 years. Individuals were divided into 3 groups as non-extraction, 2-premolar extraction, and 4-premolar extraction. Pre-treatment (T0) and post-treatment (T1) dentoskeletal and pharyngeal airway measurements were performed on cephalometric radiographs. Results: A significant increase in nasopharyngeal airway (PNS-ad2) and anterior hyoid bone movement (CV3ai-H) was observed in the 4-extraction group; whereas in the 2-extraction group, inferior oropharyngeal airway (IAS) narrowing and hyoid …
