Charting Symbols (Box 1)
Use the following instructions for charting in the
section, Accession and Subsequent Diseases and
Abnormalities Section (Box 1). Make sure you do
not enter these symbols in Box 2, Missing Teeth at
Time of Accession and Treatments Completed
After Accession. Entering these symbols in the
wrong area would prevent differentiation between
the caries and the restorations. Figure 2-21
illustrates charting symbols for Box 1.
CARIES.On the diagram of the tooth affected,
draw an outline of the carious portion, showing
approximate size, location, and shape; block in solidly.
DEFECTIVE RESTORATION.Outline the
defective restoration, including the carious or
otherwise defective area, and block in solidly.
UNERUPTED TOOTH.Outline all aspects of
the tooth with a single oval. This includes impacted
INCLINATION (TILT) OF IMPACTED
TEETH.Draw an arrow of the facial aspect of the
crown portion of the diagram that indicates the
direction of the long axis of the tooth.
EXTRACTION (REMOVAL) INDICATED.Draw
two parallel vertical lines through all aspects of the
tooth and roots involved. This applies also to
unerupted teeth when removal is necessary.
RETAINED ROOT.Draw a horizontal line on
the root showing the level of retention. Place an "X" on
the missing area. Draw two parallel lines in the
direction of the long axis of the root through the part
that is retained if extraction is indicated.
fracture line in the relative position on the crown or
approximate size, form, and location of the periapical
radiolucencies, such as an abscess or cyst.
FISTULA.Draw a straight line from the
involved area, ending in a small circle in a position on
the chart corresponding to the location of the tract
orifice (opening) in the mouth.
UNDERFILLED ROOT CANAL.Draw
vertical line from the crown toward the apex showing
the extent of the filling.
