1. Dens invaginatus: A condition found in teeth where the outer surface folds
inward.
"a tooth within a tooth"
2. Dens evaginatus: A condition found in teeth where the outer surface appears to
form an extra bump or cusp.
Mostly found in premolars
3. Radiolucent: dark
4. radiopaque: light
5. Horizontal bone loss: bone destruction parallel to a line between CEJs of
adjacent teeth
indicator of periodontal disease
6. Vertical bone loss: Adjacent to one tooth, looks like a triangular notch
indicator of periodontal disease
7. Recurrent decay: Decay is diagnosed from radiograph or from the margin of an
existing restoration.
8. Recent extraction: Socket is demarcated by radiopaque bundle bone in which
the PDL had anchored to the tooth.
After 18 months, it can no longer be distinguished.
9. Palatal tori: normal bony growth of bone on the midline of the hard palate
10. Mandibular tori: normal bony growths of the lingual aspect of the mandible
11. Mesiodens: A supernumerary tooth present in the midline between two central
incisors
can result in oral problems
-malocclusion
-food impaction
-poor aesthetics
-cyst formation
12. Concrescence: A condition of teeth where the cementum overlying the roots of
at least two teeth join together.
cause: trauma or crowding
treatment: surgical separation
