Porcelain

Post

Onlay
Amalgam


An alloy that consists chiefly of silver mixed
with mercury and variable amounts of other
metals
Appears radiopaque radiographically
Amalgam Appearances
Clinical
Radiographic
Composite



Also called a white filling
Typically consists of a resin-based matrix and
an inorganic filler (which gives the composite
wear-resistance and translucency)
May appear radiopaque radiographically
(older ones may appear radiolucent)
Composite Appearance
Clinical
Radiographic
Porcelain


Produced by mixing ceramic powder with
distilled water
Appears radiopaque radiographically
Porcelain Appearances
Clinical
Radiographic
Sealant



A tough, plastic material designed to bond to
the tooth enamel
Clear or tooth-colored material that seals the
pits and grooves
Not seen radiographically
Sealant Appearances
Clinical
Radiographic
• Not seen but
possibly a faint
radiopacity on
occlusal surface
Veneer



A thin layer of restorative material placed
over a tooth surface, either to improve the
aesthetics of a tooth, or to protect a
damaged tooth surface
Two types of materials can be used in a
veneer: composite and porcelain
Appears radiopaque radiographically
Veneer Appearances
Clinical
Post and Crown




Often, only the root portion
is left to retain the crown.
A gold casting called a post
and core
Common practice to
cement a post about twothirds of the way into a
root canal
Core = the part of the post
that protrudes from the
root canal
Post and Crown Radiograph
Fixed Partial Denture (FPD)





Designed to replace more than one missing natural
tooth
Dentist attaches an FPD to natural teeth
(abutments) or roots by cementation
Pontic = artificial tooth suspended from the retainer
casting, occupies the space formerly filled by the
crown of a natural tooth
Unit castings are joined together by connectors.
The units may be made entirely from metal,
combination of metal or resin, or from a
combination of metal and porcelain.

Surface Restorations


Examples: O, B, L, DO, MO, MOD, MOB, OL,
OB, MF, ML, DF, or DL
A dental restorative material used to
artificially restore the function, integrity, and
morphology of missing tooth structure
Appears radiopaque radiographically

How to Identify
Dental Materials Clinically

Tactile detection:
• Composite restorations have a distinct tactile feel
with the explorer that contrasts with a natural
tooth or a ceramic or porcelain restoration.
• A black line of metal may be apparent when an
explorer is used on the material.

Air:
• Aesthetic restorations may reveal a dry, chalky
appearance when air is applied.
Charting Restorations



Use blue ink and draw symbol for existing
restoration.
Place appropriate letter for restoration
material (e.g. A, C, P, V) on facial or buccal
aspect of chart, above/below root apices.
Place an “S” on the occlusal surface of the
tooth that has a sealant.
More on Charting Restorations


For a bridge, mark missing tooth/teeth with
straight line, outline the crowns of teeth, and
fill in with diagonal lines. Draw 2 sets of
parallel lines between crowns of teeth. Place
appropriate letter representing type of
material on facial or buccal.
Mark a straight line inside root areas(s)
of affected tooth for a root canal therapy.
Test YOUR Knowledge!

Identify 3 incorrect charted restorations.
Amalgam or Stain?

Name two ways you can tell if your patient has
an amalgam or a stain.
Composite or Sealant?

What is the difference between the two?
Answers



4 - “P” should be on the buccal, not the
lingual, aspect of the chart, above the apices.
14 – “S” should be on the occlusal surface
rather than on the buccal aspect of the chart,
above the apices.
31 – Blue, rather than black, ink should have
been used.
More Answers


You can use tactile detection and air. With tactile
detection, there will be a distinct difference in
sound. There is more of a solid ringing noise when
an explorer goes across a restoration and more of
a jagged, scratching noise when an explorer runs
along a tooth surface that has a stain, especially if
the tooth surface has pits.
A composite will cover a surface whereas a sealant
will cover a pit or groove.
