Figure 2-13.—Five surface amalgam restorations |
Figure 2-11.—Two and three surface amalgam restorations.
Distal-occlusal (DO): Chart by beginning at the
distal surface, and follow the grooves on the occlusal
surface to the central pit or groove (fig. 2-11, tooth #28).
Occlusal-facial (OF): Chart starting at the
central groove on the occlusal surface and down the
facial groove on the facial surface. Occlusal-facial
restorations are usually placed only on molars. On some
molars, all of the occlusal pits will be included in the
restoration (fig. 2-11, tooth #17).
Occlusal-lingual (OL): Chart starting at the
central groove on the occlusal surface and down the
lingual groove on the lingual surface (fig. 2-11, tooth
#31). Like (OF) amalgams, (OL) amalgams are usually
placed only on molars.
Mesial-occlusal-distal (MOD): Chart starting at
the mesial surface and follow the grooves on the
occlusal surfaces to the distal surface (fig. 2-11, tooth
#13 and #19). You can also think of a (MOD) amalgam
restoration as an (MO) and a (DO) amalgam restoration
joined together through the central groove on the
occlusal surface.
Mesial-occlusal-distal-facial (MODF): Chart
the same way as a (MOD) amalgam restoration, but
include the facial surface. The facial surface may be
charted in several ways. It may be charted in the facial
groove (fig. 2-12, tooth #3), or it may be wrapped
around the mesial or distal facial surface (fig. 2-12,
tooth #14). The (MODF) amalgam may include a part
of the facial surface (fig. 2-12, tooth #1), or it may
include the entire facial surface (fig. 2-12, tooth #15).
Some (MODFs) include the coronal third of the facial
surface (fig. 2-12, tooth #16).
Mesial-occlusal-distal-lingual (MODL): Chart
the same way as a (MOD) amalgam restoration, but
include the lingual surface. The lingual aspect may be
charted in the lingual groove (fig. 2-12, tooth #18) or it
may wrap around the mesial and distal surfaces in the
same manner as that discussed for the (MODF). Figure
2-12, tooth #30 and tooth #31, illustrates examples of
the (MODL) restorations that include various portions
of the lingual surfaces.
Mesial-occlusal-distal-facial-lingual
(MODFL): Chart by combining the (MODF) and
(MODL) restorations. These restorations may include
carious portions of the facial and lingual surfaces.
Figure 2-13 illustrates the different types of (MODFL)
restorations.
NONMETALLIC PERMANENT RESTORA-
TIONS.—Nonmetallic
Permanent
Restorations
include filled and unfilled resins, glass ionomer
cement and pit and fissure sealants. In the diagram of
the tooth, draw an outline of the restorations showing
size, location, and shape. Do not block in. The
following paragraphs explain how to chart nonmetallic
restorations.
Mesial (M) and distal (D): Chart these single
surfaces on the mesial or the distal side of the facial
surface. Figure 2-14, illustrates a mesial restoration (M)
on tooth #8, and a distal restoration (D) on tooth #9.
