    Nonsurgical orthodontic treatment of an adolescent girl with Class III malocclusion and asymmetric maxillary narrowing
    (Mosby-Elsevier, 2008) Hamamci, Nihal; Basaran, Guevenc; Tumen, E. Caner; Ozdemir, Eylem
    Class III malocclusion is a difficult anomaly to understand. Because not all Class III patients are candidates for surgical correction, patient assessment and selection are especially important in diagnosis and treatment planning. In this article, we report the orthopedic treatment of a teenage girl with a severe skeletal Class III malocclusion. Her ANB angle was -4.5 degrees, and she had a 2-mm anterior crossbite, a 1-mm overbite, and a posterior asymmetric crossbite (greater on the left side). The patient refused surgery. We used a rapid palatal expansion appliance to expand the maxilla, standard edgewise brackets to align the teeth, and reverse headgear to bring the maxilla forward. We performed symmetric expansion, but, because of the asymmetric crossbite in the maxilla, we designed a modified apparatus that permitted greater relapse on 1 side. In this way, the posterior crossbite was ideally corrected by the end of treatment, and ideal overjet and overbite relationships, functional occlusion, and an esthetic facial appearance were all achieved.

    Types of Rickets, Dental and Histologic Findings: Review of the Literature
    (Assoc Apoio Pesquisa & Saude Bucal-Apesb, 2009) Tumen, E. Caner; Yavuz, Izzet; Atakul, Fatma
    Introduction: A disease that occurs during childhood, rickets is the failure of growing bone to mineralize. Many skeletal and radiographic changes can ocur because of the lack of calcified osteoid and the buildup of unossified cartilage. Proper bone formation requires a complex interplay of several organs and chemicals, and vitamin D deserves special mention because any disturbance in its production, absorption, or metabolism is paramount in the development of rickets. The pathophysiology of the disease is thought to be impaired phosphate transport, especially decreased phosphate resorption in the renal proximal tubule, as well as in the intestine. In most cases, the diagnosis is established with a thorough history and physical examination and confirmed by laboratory evaluation. Early diagnosis is essential because morbidity can be minimized if children are treated before eight months of age. Objective: The aim of this literature review is to present various types of rickets with clinical features and the dental findings, preventive measurements and treatments. Conclusion: The denrist as well as the pediatrician should be made aware of the features of this disorder so that early intervention can prevent subsequent serious and more invasive dental procedures.
