[A contribution to the differential diagnosis of odnotogeneous cysts]

Problems concernint the diagnosis and differential diagnosis of odontogenic cystic lesions of the jaw are discussed with reference to a series of patients and some specially selected cases. The use of isotope examination is often of particular significance in coming to a decision. The position and value of scintigraphy has been demonstrated by referring to the literature and to our own investigations. The often difficult differentiation from certain types of odontogenic tumours is also discussed.
