History of DM
Early history:

Archaeological Studies

• Hippocrates used gold wire ligature.
• Filling of carious teeth involved use of Lint,
Lead
• Cadaver or animal teeth used for
replacement!
Renaissance and enlightenment age:
• Lost wax technique by Benvenuto Cellini
1558 Fonzi: Porcelain teeth
• Taveau: first to prepare amalgam
(Silver paste).
• The American Journal of Dental Sciences
1839.
Why we need to study DM?
• Hyena
OR
Crocuta Crocuta
With its teeth Hyena can crush the prey bone and chew
them up into abite-sized pieces.!!!
• But what about
human teeth
- Oral environment
* Temperature
* Saliva and fluids
* Micro-organisms
* Occlusal forces
Why we need to study DM
Why we need to replace
missing tooth
structure/ teeth
• Appearance
• Function
• Any other reasons?
• So why we
need to study
DM?!
