Study Notes
Classification of Calculus
-
Class I:
- Light supragingival or subgingival calculus and/or stains on mandibular anterior teeth
- May include one or two additional isolated deposits
- Presence of more plaque than calculus
- Minimal to no soft debris
-
Class II:
- Moderate supragingival calculus
- Subgingival calculus detectable by explorer on at least 14 teeth, including lower anterior teeth
- Explorer detects calculus that causes a "click" sound when passed over
-
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
- Associated with periodontal involvement, exhibiting moderate to deep pockets (5-7mm)
- Moderate to severe bone loss and tooth mobility likely
- Treatment typically occurs in sextants or through non-surgical periodontal therapy (NSPT)
