Abstract

Oral involvement in diffuse Langerhans Cell Histiocytosis (LCH) is a rare condition in children. Clinical symptoms are early loss of teeth, pain, gingival swelling and oral ulceration's. This case report aims to present and compare the preliminary and fifteenth-year clinical, radiographical and dental features a LCH patient and to suggest principles for long-term dental treatment planning of LCH. A 4.5 years old LCH patient (with Diabetes Insipidus), with the complaint of nutritional deficiency and chewing difficulties due to early, spontaneous exfoliation of the deciduous teeth was applied. Examinations showed that deciduous molars were mobile because of the destruction of supporting alveolar and basal bone. After dental treatments (extractions, restorative treatments etc.), removable space maintainers were applied. The patient could not attend the following appointments at all. After 15 years, bilaterally, molar open-bite has been detected and orthodontic treatment with orthognathic surgery has been indicated
