•Hippocrates used gold wire ligature.
•Filling of carious teeth involved use of Lint,
Lead
•Cadaver or animal teeth used for
replacement!

•But what about
human teeth
-Oral environment
* Temperature
* Saliva and fluids
* Micro-organisms
* Occlusal forces

Why we need to replace
missing tooth
structure/ teeth
•Appearance

•So why weneed to study
DM!?
