The histiocytosis X representing eosinophilic granuloma, the Letterer-Siwe disease, and the Hand-Schuler-Christian syndrom that may cause bone or intraoral lesions is now called the Langerhans-Cell-histocytosis (LCH).

The findings observed were; bone loss in the skull, severe bone resorption in the maxilla and mandibula, loosening and exfoliation of the teeth, intensive gingivitis, malaligment, and malocclusion of the primary dentition.
As for the dental treatment, composite resin filling and extraction were performed under local or general anesthesia, and after extraction of 15 Permanent teeth, anterior acrylic partial dentures were constructed to maintain space.
