Non Caries Lesions Flashcards
What’s the most affected teeth in microdontia ?
Max lateral incisors and third molar
Which endocrinologist defects does the micro and macro associated with ?
Micro , pituitary dwarfism
Macro , pituitary gigantism ( rare )
What’s relative generalized microdontia ?
Normal or slight smaller than normal
Present in jaw larger than normal
What’s relative generalized macrodontia ?
Normal or slight large teeth in small jaw
Which teeth more likely to be affected by macrodontia ?
3rd mandibular molar
What’s is number and eruption defects ?
Surenumerary teeth
Anodontia
Impaction
What’s supernumerary ?
Results from continued proliferation of permanent or primary dental lamina to form the third tooth germ
Teeth may have
Normal morphology
Rudimentary
Miniature
More often in
permanent dentition
cleidocranial dysplasia can cause ?
Supernumerary teeth
Which teeth more suspectible to supernumerary ?
Maxillary anteriors espicially incisors
Mandibular premolars
What’s adontia and Edentulism ?
Adontia , congenital lake of teeth , absence
Edentulism , due to trauma , injury…
What’s adontia types ?
Types:
Complete anodontia
Partial anodontia:
Hypodontia
Oligodontia
Pseudoanodontia
False Anodontia
With which anomalies the ectodermal dysplasia associated ?
Complete adontia
Hypodontia , partial adontia ?
A congenital condition of having fewer than the normal complement of teeth.
Oligodontia ?
congenital absence of some of the teeth.
Mostly lateral incisors, second premolar or third molars are absent
Pseudoanodontia ?
Clinically missing teeth because of impaction or delayed eruption
False Anodontia ?
When primary teeth are exfoliated or extracted
What’s impaction reasons ?
Condition when the tooth is not erupted due to :
Lack of place in the dental arch
Obstruction from crowding
Obstruction from other Physical
barrier
Abnormal eruption path
because of unusual orientation of the tooth germ
Shape and form abnormality
Which teeth prone to be impacted ?
Most often affects :
mandibular 3rd molar
, maxillary canines
Less commonly :
Premolars
Mandibular canines
Second molars
What’s ankylosis ?
Fusion of the tooth to the surrounding bone
With local loss of periodontal ligament ,
bone and cementum become inextricably mixed due to fusion of the tooth to alveolar bone
Also known as “submerged teeth”
Mostly affected teeth :
Primary teeth, most commonly mandibular second molars
The teeth undergo variable degree of root resorption
what’s happen to ankyloses teeth when the adjacent permanent erupt ?
Appear below the occlusion level
