[The use of spatial image filtration in the diagnosis of tumors and tumor-like processes of the jaws in children].

34 children were examined for tumours and tumor-like jaws diseases odontomas, giant cell tumours, fibrous osteodysplasias, epulides, eosinophilic granulomas. Roentgenograms and tomograms of the patients have undergone space filtration on the device for the DAR-2 roentgenogram analysis with separation of the upper and middle space frequencies of the picture. Space filtration separated features of the picture having differentially diagnostic meaning and characterizing the particularities of the tumour structure, it's bone border, alteration of the surrounding soft tissues.

[X-ray and morphological changes in fibrous osteodysplasias of the jaws in children].

Thirty-three children were examined operated on for histologically verified fibrous osteodysplasia. X-ray examinations of the maxilla and mandible were carried out in the nasofrontal and lateral projections, roentgenograms were made in the semiaxial and naso-forehead projections, and intraoral roentgenograms of the teeth and alveolar processes, orthopantomograms of the mandible, and linear tomograms were made. Five variants of an x-ray picture of fibrous dysplasia were distinguished which should be taken into consideration in differential diagnosis.
