NON-ODONTOGENEOUS TUMORS
A-BENIGN TUMORS
1-CENTRAL REPEAT GRANULOMA WITH GIANT CELLS
- Mandible, premolar region
- Young woman
- Radio clarity with well-defined contours
- In soap bubble
- Multilocular
- Thinning of the cortex
2-PERIPHERAL REPAIR GRANULOMA WITH GIANT CELLS
- Young adult
- Female gender
- Up to 2 cm
- Grows along the desmodontal space
3-HISTIOCYTOSIS X
- Teeth hanging within a transparent area: bone destruction
- Loss of lamina dura
- Scalloped contours
- Peripheral sclerosis
4-CHONDROMA
- Anterior and medial part of the maxilla.
- Well limited
- Pinhead calcifications
5-DESMOBLASTIC FIBROMA
- Multilocular
- Well defined
- Very thinned cortex, see rupture
6-OSSIFYING FIBROMA
- Can be bulky
- Teenager
- Ground glass opacity associated with calcifications
- Pushes back the nasal cavity and maxillary sinuses
7-FIBROUS DYSPLASIA
- Start between 5 and 15 years old
- Bone differentiation disorder
- Blown cortex especially at the maxilla level
- Asymmetry
- mandible: transparent cystoid areas juxtaposing with opaque areas
8-OSTEOID OSTEOMA
- Mandible
- Young woman
- Less than 1 cm
- Bone density opacity in a radio transparency
9-OSTEOMA
- Peripheral or central
- All ages
- Very dense and well-limited opacity
10-EXOSTOSIS AND ENOSTOSIS
- Mental protuberance and angular process of the mandible
- Opacity
- Post traumatic and inflammatory
11-BONE ANGIOMA
- Maxilla and mandible
- Gem
- Soap bubbles
- Calcification
- Osteolysis zones
- Root opacity
- Cortical deformation
B-MALIGNANT TUMORS
1-SARCOMA
- Male predominance
- Mandible
- Bone destruction, osteolysis
- Cortical rupture
- Radiating spicules
2-TUMOR INFLITRATION
- Loss of lamina dura
- Desmodontal enlargement
- Moth-eaten appearance
3-METASTASES
- Secondary tumor
- Moth-eaten or speckled appearance

- Alongside histology, radiology helps guide the diagnosis .
- Imaging allows the tumor to be characterized and a pre- therapeutic assessment to be carried out .
NON-ODONTOGENEOUS TUMORS
Early cavities in children need to be treated promptly.
Dental veneers cover imperfections such as stains or cracks.
Misaligned teeth can cause difficulty chewing.
Dental implants provide a stable solution to replace missing teeth.
Antiseptic mouthwashes reduce bacteria that cause bad breath.
Decayed baby teeth can affect the health of permanent teeth.
A soft-bristled toothbrush preserves enamel and gums.
