Description
A non-surgical dental procedure to remove plaque, calculus, and infected cementum from tooth roots and smooth root surfaces to promote periodontal healing.
Main Uses
Primary purpose is the mechanical removal of subgingival dental plaque, calculus, and diseased cementum to treat chronic periodontitis and prevent disease progression. Clinically indicated for patients with probing depths ≥4 mm, bleeding on probing, clinical attachment loss, radiographic bone loss, and/or signs of active inflammation. Also used as part of initial periodontal therapy (Phase I), supportive periodontal therapy (SPT), and pre-surgical preparation. Not indicated for gingivitis alone (supragingival cleaning suffices).
Normal Range
Gingival scaling (subgingival scaling) is a clinical 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 plaque/calculus removal confirmed visually and tactilely with periodontal probes and explorers.
Low Values - Possible Causes
N/A — As a therapeutic procedure (not a diagnostic assay), 'low values' do not apply. However, suboptimal outcomes (e.g., residual calculus, inadequate root debridement) may result from: 1) Operator inexperience or insufficient training, 2) Inadequate patient access due to anatomical constraints (e.g., furcations, deep narrow pockets), 3) Use of dull or improperly adapted instruments, 4) Failure to achieve proper anesthesia leading to incomplete treatment, 5) Patient noncompliance with pre- or post-procedural instructions affecting visibility or healing.
High Values - Possible Causes
N/A — As a non-quantitative intervention, 'high values' are not defined. However, excessive or inappropriate application may lead to complications including: 1) Iatrogenic root surface damage (e.g., gouging, excessive cementum removal), 2) Prolonged postoperative sensitivity or dentin hypersensitivity, 3) Gingival recession due to aggressive instrumentation, 4) Increased risk of bacteremia in immunocompromised or high-risk cardiac patients, 5) Unnecessary treatment in patients with healthy periodontium (i.e., overtreatment without indication).
