Introduction to Charting. Tooth Surfaces: M = mesial D = distal O = Occlusal B = buccal F = facial I = incisal L = lingual

Transcription

1 Tooth Surfaces: M = mesial D = distal O = Occlusal B = buccal F = facial I = incisal L = lingual When combining tooth surfaces, as in defining cavity preparations or restorations, there are some spelling and pronunciation changes. When combined, the surfaces loose their al suffix, and take on an O suffix. Example: Example: a restoration that covers the mesial, incisal, and distal surfaces of a tooth would be written as mesioincisodistal. The last surface listed in the combination, such as distal in his example, maintains the al suffix. a restoration that covers the mesial, occlusal, and distal surfaces of a tooth would be written as mesio-occlusodistal. Whenever two o s are back to back, such as in this example between mesio and occluso, they are hyphenated. Cavity Classifications: Class I: Class II: Class III: Class IV: Class V: One surface, anterior or posterior teeth, lingual, facial, or buccal only, not involving an Interproximal surface Examples: O-#3, L(pit) #7, B-#19 Two or more surfaces, posterior teeth only, involving at least one Interproximal surface. Examples: DO-#3, MOD-#29, MODBL-#31 One or more surfaces, posterior teeth only, involves at least one Interproximal surface, but not the incisal edge (incisal angel) Examples: D-#8, ML-#23, DF-#10 One or more surfaces, anterior teeth only, involves at least one Interproximal surface, and the incisal edge (same as class III, except it involves the incisal) Examples: DI-#8, MIL-#23, DIF-#10 One surface, lingual, facial, and buccal only, anterior or posterior teeth, along the gumline, posterior teeth, along the gumline, not extending to the Interproximal, must be contained to the cervical (gingival) one-third of the tooth Examples: L(cervical)-#18, F(cervical)-#11

2 PROCEDURE Extraction Impaction PFM (Porcelain fused to metal) FGC (Full gold crown) Veneer RCT (Root canal treatment) Abutment Pontic Bridge Amalgam Composite Fracture Periapical Abscess Inlay Onlay Sealant Denture Partial Denture Retained Primary Tooth Supernumerary Tooth CHARTING INSTRUCTIONS Large X through entire tooth and roots. Large circle around entire tooth and roots, and write an imp above or below impacted tooth. Always charted in blue Outline entire crown portion of tooth Outline entire crown portion of tooth and fill in outlined area with diagonal lines. The lines represent gold. Outline only the facial surface of the tooth. Denote a c for a composite veneer, or a p for a porcelain veneer Draw one line up/down the center of each root of the tooth extending all the way to the apex but not beyond. If your tooth chart doesn t show the root portion of the tooth, draw them in Same as a crown. Outline entire crown portion of tooth and fill it in with lines for gold, or leave blank for porcelain Same as an abutment, but place an X over root portion of the tooth indicating the tooth is missing. To indicate that the pontics and abutments go together as part of a bridge tie the units of the bridge together with a bracket above or below the units in the bridge. Chart the surface(s) of the restoration and color in completely. Chart the surface(s) of the restoration but do not color in. Charted as a jagged, zigzagged diagonal line on the facial surface in red Charted as a circle at the apex of the tooth Charted as a Class II restoration with a p for porcelain or with diagonal lines for gold Circle the occlusal surface only and fill in with diagonal lines for gold, or leave blank for porcelain and denote with a P Circle the occlusal surface only and chart a letter s in the center of the occlusal surface on the tooth Make one large X through all missing teeth (no need to x out each tooth individually) and then write in FUD or FLD above or below the teeth X out missing teeth and place a bracket that encompasses teeth replaced in the partial above or below teeth. Write PUD or PLD Cross out the permanent tooth number on the tooth chart and replace it with the letter of the primary tooth. Above or below the tooth write retained Draw in the extra tooth/teeth as they are positioned in the arch. Use the radiograph as your guide. If no radiograph is available, draw the tooth/teeth in between the teeth but below gum line level remember, they are impacted in the bone. Write supernumerary above or below the tooth

3 PROCEDURE Horizontal Impaction Recurrent Decay Maryland Bridge Temporary Stainless Steel Crown Diastema Dental Implant CHARTING INSTRUCTIONS Chart the impaction then draw an arrow inside the circle in the direction the crown is facing Outline the already charted restoration (should be done in blue) with red Outline the crown portion of the tooth that is missing and draw the wing-like extension over the lingual surfaces of the abutment teeth Circle the occlusal portion of the tooth and indicate the temporary material with a Z Outline the crown portion of the tooth and fill in with wavy lines Draw 2 straight lines in between the teeth where the diastema is Outline the root portion of the tooth and fill in with horizontal lines

Whenever possible, charted decay/restorations should resemble the size, shape, the decay/restoration in the mouth Chart all restorations/decay on the facial surface of the tooth, unless it involves the Class III decay/restorations should not touch the incisal edge, and should be the Chart all Class I decay/restorations in the pit or cingulum area of the tooth on the both the facial and All class IV decay/restorations involving the lingual surface should be charted on lingual portion of the tooth, and should be a mirror image of each other Fractures should be charted on the facial surface only, from the Interproximal surface to the incisal edge on an angle (diagonal) Posterior teeth: Class I decay/restorations should be charted in the occlusal, buccal and lingual pits only and should never touch the edges of the tooth, or it will appear that it involves the Interproximal surface the tooth, unless the Class II decay/restorations should be charted entirely on the occlusal surface of buccal or lingual surfaces are involved Class II decay/restorations should be charted in a triangular or dumbbell/bow- mesial, occlusal, and distal surfaces. Class II decay/restorations involving the buccal or lingual surfaces should be developmental grooves. tie shape on the charted along the Anterior and Posterior teeth: Class V decay/restorations should be contained to the cervical/gingival one third of the tooth, to the
