Mesiodens?
|
supernumerary between maxillary central incisors
|
|
Parateeth?
|
supernumerary in molar area
|
|
Distodens?
|
supernumerary distal to third molar
|
|
macrodontia?
|
teeth larger than normal
|
|
Transposition?
|
two teeth have exchanged position
|
|
Fusion?
|
combining of adjacent tooth germs leading reduced number of teeth
|
|
Concrescence?
|
Roots of two or more teeth are united by cementum.
|
|
Gemination?
|
tooth bud attempts to divide leading to invagination of crown
|
|
Taurodontism?
|
Longitudinally enlarged pulp leading to increased distance between CEJ and furcation
|
|
Dilaceration?
|
Disturbance in development leads to sharp bend or curve in the tooth.
|
|
Dens in Dente (dens invaginatus)
|
infolding of outer surface into the interior of the tooth.
|
|
Dens Evaginatus?
|
outfolding of the enamel organ leading to polyp like enamel on occlusal surface
|
|
Amelogenesis Imperfecta?
|
malformed or relative lack of enamel of nearly all the teeth
|
|
dentinogenesis imperfecta
|
roots and pulp chambers are generally small and under develped
|
|
osteogenesis imperfecta
|
brittle bones characterised by osseous fractures
|
|
dentin Dysplasia?
|
type 1 = the roots are short or abnormally shaped. The pulp chambers completely fill in before eruption. Periapical radiolucencies (cysts or granulomas)
Type II - pulp is obliterated after eruption |
|
Odontogenesis Imperfecta?
|
ghostlike appearance. Large pulp chambers and wide root canals. Poorly outlined roots are short. Teeth that don't erupt are hypomineralised and appear to be resorbing.
|
|
Enamel Pearl?
|
Smooth round and of similar radiographic density as enamel.
|
|
Talon Cusp?
|
hyperplasia of the cingulum of a mindibular or maxillary incisor.
|
|
Turners Hypoplasia?
|
enamel irregularities appear as ill defined rediolucencies on the crown.
|
|
Congenital Syphilis?
|
30% of people with congenital syphilis develop dental hypoplasia involving permanent incisors (hutchingsons teeth - tapering at mesial and distal surfaces)and first molars (mulberry molars)
|
|
Internal resorption?
|
radiolucent and round, oval or elongated within the root or crown and continuous with the image of the root canal.
|
|
External Resorption?
|
smooth resoption of the tooth structure resulting in blunting of the root apex . Almost always the the bone and lamina dura follow the resorbing root and present a normal appearance around the shortened structure. Occasionally may involve lateral surfaces of roots.
|
|
Pulp Stones?
|
Foci of calcification on the pulp chamber. Radiopaque structure in the root canal.
|
|
Pulpal Sclerosis?
|
Diffuse calcification in the pulp chambers and canals . Generalised, ill defined collection of fine radiopacities throughout the pulp chambers and canals
|
|
Hypercementosis?
|
Excessive deposition of cementum on the tooth roots.
|
