Some genetic disorders are associated with recurrent inflammation of the oral mucosa and with periodontal disease. Of the various incarnations of glycogen-storage diseases (GSD), type Ib is such a disorder. It is caused by a lack of polymorphous nuclear neutrophilic granulocytes (PMN) and PMN dysfunction. The present case report relates to a patient suffering from GSD type Ib and describes the oral findings between the ages of seven and 19 years. His oral situation was characterized by frequent ulcerations in various regions of the oral mucosa, persistent gingivitis, and advanced periodontal disease, initially affecting the deciduous molars (F3 furcation involvement). A comprehensive preventive dental-care program and excellent compliance on the part of the patient could not prevent periodontal destruction of the mandibular right first permanent molar (4 mm attachment loss, F2 furcation involvement).
