Description
Estimated cost for Scaling and root planing at general public hospitals in China is about ¥210-960, and at Grade 3A hospitals about ¥300-1200, varying by hospital tier and region.
Main Uses
Primary purpose is the mechanical removal of subgingival dental calculus, endotoxin-coated plaque biofilm, and diseased cementum from root surfaces to treat chronic periodontitis and prevent disease progression. Applicable in patients with probing depths ≥4 mm, bleeding on probing, radiographic bone loss, and clinical signs of active inflammation. Also used as part of periodontal maintenance therapy and pre-surgical preparation.
Normal Range
Gingival scaling (subgingival scaling) is a clinical dental procedure, not a laboratory test with numerical values; therefore, there is no 'normal range' in terms of quantitative metrics. Clinical success is assessed qualitatively using parameters such as probing depth ≤3 mm, absence of bleeding on probing (BOP), no suppuration, clinical attachment level stability, and absence of subgingival calculus or biofilm confirmed by tactile and visual inspection.
Low Values - Possible Causes
N/A — This is not a quantitative diagnostic test yielding low/high numerical values; 'low' does not apply. However, inadequate or incomplete scaling (e.g., due to operator error, poor access, or patient noncompliance) may result in residual calculus/inflammation, mimicking 'subtherapeutic' outcomes.
High Values - Possible Causes
N/A — No numerical output exists; 'high' values are not defined. Excessive or traumatic instrumentation (e.g., root surface gouging, cementum removal >100 µm, or iatrogenic recession) may occur but reflects procedural technique error—not a measurable 'high value'.
