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 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.Continue Reading
