-
Class II:
- Moderate supragingival calculus
- Subgingival calculus detectable by explorer on at least 14 teeth, including lower anterior teeth

-
Class III:
- Moderate to heavy supragingival calculus present
- Subgingival calculus detectable by explorer throughout the mouth
- Specifically affects mesials and distals of bicuspids and molars
- Calculus spur visibility on radiographs
-
Class IV:
- Heavy supragingival and/or subgingival calculus present throughout the mouth
- May appear as a continuous band, with or without soft debris
