Stains/Tooth Deposits Flashcards
Originates within the tooth from developmental and systemic disturbances
Endogenous
Can be removed mechanically by either the patient or the dental professional
Exogenous stain
Two types of exogenous stains
Extrinsic and Intrinsic
Extrinsic stain
On exterior of teeth and can be removed
Intrinsic
Exogenous origins but have become part of the tooth and can not be removed
3 Examples of Developmental Endogenous stain
Amelogenesis imperfecta , Dentinogenesis imperfecta , and Dentin dysplasia
Endogenous stain can also be from
Drug-induced
Drug Induced Endo stain can affect
Both primary and permanent teeth
Examples of how drug induced endo stain occurs (2 things)
- Exposure to tetracycline between the 5th month and age 8
* Fluoride ingestion (dental fluorosis)
Examples of Enamel Hypoplasia
Febrile illness , local infections or trauma to primary teeth.
Trauma during tooth maturation, endocrine, metabolic, and unknown carries
Enamel hypoplasia is an example of
Endogenous
The only stain a RDH can remove
Exogenous Extrinsic !
Non-mineralized Deposits (4 of them)
Acquired Pellicle, plaque (biofilm), material alba, food debris
Describe Acquired Pellicle
Thin, translucent, bacteria free layer (acellular)
Acquired Pellicle covers
