1

Originates within the tooth from developmental and systemic disturbances

Endogenous

2

Can be removed mechanically by either the patient or the dental professional

Exogenous stain

3

Two types of exogenous stains

Extrinsic and Intrinsic

4

Extrinsic stain

On exterior of teeth and can be removed

5

Intrinsic

Exogenous origins but have become part of the tooth and can not be removed

6

3 Examples of Developmental Endogenous stain

Amelogenesis imperfecta , Dentinogenesis imperfecta , and Dentin dysplasia

7

Endogenous stain can also be from

Drug-induced

8

Drug Induced Endo stain can affect

Both primary and permanent teeth

9

Examples of how drug induced endo stain occurs (2 things)

• Exposure to tetracycline between the 5th month and age 8

• Fluoride ingestion (dental fluorosis)

10

Examples of Enamel Hypoplasia

Febrile illness , local infections or trauma to primary teeth.

Trauma during tooth maturation, endocrine, metabolic, and unknown carries

11

Enamel hypoplasia is an example of

Endogenous

12

The only stain a RDH can remove

Exogenous Extrinsic !

13

Non-mineralized Deposits (4 of them)

Acquired Pellicle, plaque (biofilm), material alba, food debris

14

Describe Acquired Pellicle

Thin, translucent, bacteria free layer (acellular)

15

Acquired Pellicle covers

Teeth, restorations, calculus and dental appliances

16

Significance of Acquired Pellicle (+)

Provides protective barrier against acids and Keeps surfaces moist

17

Significance of Acquired Pellicle ( - )

Means of plaque accumulation , and acts as an attachment for calculus

18

3 steps of Plaque Formation

Pellicle formation, bacterial colonization and plaque maturation
