1. Dental Charting Chapter 14

2. Dental Charts Two areas: Dental charting Record treatment Anatomical versus geometric Computerized

3. Dental Charts Charting is a part of the patient’s legal record and must be done correctly. The initial charting is normally done on the first exam. Anatomical charts show the crown of the tooth, the crown and a portion of the tooth, or the crown and the complete root. Geometric charts show the teeth as circles. Computerized charting helps standardize. It’s more efficient, fewer mistakes are made, and it’s easier in many ways. Light pens are used to highlight and color.

4. Numbering Systems The Universal/National system was developed in 1968 and is most commonly used in the United States. FDI was developed to provide an international system for coding teeth. Canada and European countries use this the most. In 1996, the ADA adopted this system and the universal system for tooth numbering. The Palmer system is not very common, but it’s still used in some offices.

5. Cavity Classifications Six standard classes Cavity is caries The classifications of cavities were developed by G. V. Black. These are still the classifications being used today.

6. Cavity Classifications Class I Developed cavities in pit and fissures They are found in the occlusal surfaces of posterior teeth (premolars and molars), buccal or lingual pits on molars, and lingual pit near the cingulum of the maxillary incisors.

7. Cavity Classifications Class II Proximal surfaces on posterior teeth MO restoration MOD restoration

8. Cavity Classifications Class III Interproximal surface of anterior teeth They can be found on canines, lateral incisors, and central incisors.

10. Cavity Classifications Class V Cervical third of facial Lingual surface of tooth Often this class of cavity occurs because the patient often sucks on sweets. You may also find an entire quadrant with this type of cavity because a patient takes medications, chews gum, or drinks soft drinks over long periods of time.

11. Cavity Classifications Class VI Worn away due to abrasion This type is not part of the original five standard classification of cavities developed by G.V. Black. It was later classified to better label those cavities that involve the incisal or occlusal surface that has been worn away due to abrasion.

12. Dental Check Which type of caries commonly occur in a patient that regularly sucks on sweets? Class V

13. Charting When a dental assistant is documenting the chart to record the surfaces of the teeth that need restoration, abbreviations for single-surface restorations are used. Each surface is abbreviated using the first letter of the surface, capitalized.

14. Abbreviations of Tooth Surfaces Simple involves one tooth surface I: incisal M: mesial D: distal B: buccal O: occlusal F: facial

15. Charting If two or more surfaces are restored, then a combined abbreviation is used. For example, to identify the restoration on the distal and occlusal surfaces, the term is disto -occlusal restoration or DO restoration.

16. Abbreviations of Tooth Surfaces Compound involves two surfaces DO: disto -occlusal MO: mesio -occlusal MI: mesio -incisal DI: disto -lingual LI: linguo -incisal DL: disto -lingual OB: occluso -buccal

17. Charting If three surfaces are combined, the same principle is applied to the second word, as well (e.g., mesial- occlusor -distal or MOD restoration). If a mesial surface of the tooth is restored with another surface, it is always used first. Occlusal and lingual normally fall in the last position.

18. Abbreviations of Tooth Surfaces Complex involves more than two surfaces MOD: mesio - occluso -distal MODBL: mesio - occluso - disto - bucco -lingual

19. Basic Charting Terms Abscess- a localized area of infection. Bridge- prosthetic device placed between teeth covering space created by a missing tooth Abutments-attaching sides Pontic - middle area

20. Basic Charting Terms Cantilever bridge- attached to only one side

21. Basic Charting Terms Maryland bridge-has wings on the pontic that are attached to lingual sides of adjacent teeth

22. Basic Charting Terms Crown (cap)-A crown can be made from gold, porcelain, steel, or plastic. Full crowns cover the complete tooth, while you can also have three-quarters covering three-fourths of the tooth. Permanent Temporary

23. Basic Charting Terms Denture Complete Partial Dentures are needed if all natural teeth in one arch are missing. A partial denture is needed if only some natural teeth are missing.

24. Basic Charting Terms Diastema-space between the maxillary central incisors It could also refer to the space between two adjacent teeth in the same dental arch.

25. Basic Charting Terms Drifting- opposing teeth move or erupt into space after a tooth has been removed

26. Basic Charting Terms Gold foil- when several layers of pure gold are placed in preparation for restoration

27. Basic Charting Terms Incipient-is beginning decay that has not broken through the enamel yet. Some dentists will denote these areas in charts to carefully watch.

28. Basic Charting Terms Mobility when a tooth moves in the socket due to periodontal disease or trauma. A numbering system is used to record how many millimeters the tooth moves

29. Basic Charting Terms Overhang is excessive restorative material found interproximally near the gingiva.

30. Basic Charting Terms Periodontal pocket is space in the gingival sulcus created by periodontal disease. A healthy depth is 1 to 3 mm; beyond that is considered a pocket.

31. Basic Charting Terms Restoration is where replacing the tooth structure occurs, which is also known as fillings.

32. Basic Charting Terms A root canal is where the pulp is removed and filled with other suitable materials.

33. Basic Charting Terms A sealant is a resin material used to seal pits and fissures to prevent decay.
