Chapter 1: History Flashcards
They used gold bands and wires for the construction of partial dentures.
Phoenicians (After 2500 BC)
Etruscans (After 800 BC)
He was the first to use gold foil for dental restorative purposes in 1948.
Johannes Arcelanus
These were used to position extracted teeth in place of the missing teeth by the Phoenicians after 2500 BC and the Etruscans after 800 BC.
Gold Bands
When was the earliest recorded evidence of a tooth implant materials?
As early as 700 BC
They were credited for the earliest documented evidence of tooth implant materials.
Etruscans
They used implants consisting of seashell segments placed in anterior tooth sockets.
Mayans, 600 AD
They used hammered gold inlays and stone or mineral inlays for decorative purposes.
Mayans and Aztecs
They performed tooth mutilations using hammered gold, but not for decorative purposes
Incans
He is the Father of Dentistry.
Fauchard / Pierre Fauchard
In 1728, Fauchard published a treatise describing many types of dental restorations, including a method for construction of artificial dentures made from _______.
Ivory
In 1756, he described a method for making impressions of the mouth in wax from which he constructed a model with plaster of Paris.
Pfaff / Phillip Pfaff
In 1792, he patented a process for the construction of porcelain teeth.
De Chamant / Nicolas Dubois de Chémant
In the early 1800, this material was introduced soon thereafter the process for the construction of porcelain teeth was patented.
Porcelain Inlay
The first dental amalgam or “silver filling” was produced in which country?
France
The dental amalgam reached the U.S. in which year?
approx. 1830
Materials that were introduced in the 1850’s.
- Amalgam with copper
- Plaster of Paris as an impression material
- Gutta Percha
- Metal Mixtures based on gold and platinum
- Vulcanite
- A compound made of zinc oxychloride as cementing agent and a restorative.
It is a hard rubber material which was introduced as a replacement for ivory dentures.
Vulcanite
It is used for filling the root canals.
Gutta Percha
Two materials that were introduced to secure circular gold inlays into prepared cavity in the late 1880.
Zinc Phosphate and Silicate Cement
Who is the Father of Modern Dentistry and the pioneer of restorative dentistry?
Dr. G.V. Black
When did G.V. Black perfected the formulation and use of dental amalgam in his laboratory at Northwestern University in Chicago, Illinois.
End of 19th century (1895)
In 1910, he brought the lost wax technique to the dental field.
Taggert / William Taggart
What is the lost wax technique all about?
The accurate production of metal inlays, crowns, and bridges made of gold-containing alloys were made possible.
This prevents tooth demineralization.
Fluoride
The use of fluoride began in year ______.
1915
In 1935, this material was introduced as a denture base material to support artificial teeth.
Polymerized Acrylic Resin
In 1944, _______________ began and caries incidence was reduced by 50%.
Controlled water fluoridation (1 ppm)
Important Contributions in the 1950s
- Stainless steels for orthodontics
- Non-noble metals (gold-free) for casting process
- Elastic impression materials
- Dental composites used with acid etch technique
- New noble casting metals
- Pit and fissure sealants
- High copper amalgam
Important Contributions in the 1970s
- Glass ionomers and polycarboxylates were developed
- New wires for orthodontics
- New composites
- Adhesives that could bond to dentin
- More accurate impression materials
- Ceramics
In 1980s, more developments were brought further in. These developments include:
- Dentin Adhesives
- Composites and Ceramics
- Light-Cured Liners
- Glass Ionomers and Sealants
Development in 1990s.
- Simplified Dentin Adhesives
- Reinforced Ceramics for Fixed Bridges
- Resin-modified glass ionomers
- Composites
- Low-fusing Porcelains
- New Root Canal Fillers
Who are the Important Researchers in the Field of Dental Materials?
- Wilmer Souder
- George C. Paffenbarger
- William T. Sweeney
