Disclosing Agent

A liquid or tablet that stains plaque on teeth, making it visible. This helps patients understand where they need to brush better.

Purpose of Disclosing Agents

Disclosing agents help patients visualize plaque, understand where to brush better, and motivate them to improve their oral hygiene. They also serve as a tool for self-monitoring and provide visual support for oral health advice.

Types of Disclosing Agents

Disclosing agents come in different colors: pink for 24-hour-old plaque and aqua for very acidic plaque. Some agents also show different colors based on the plaque's age and acidity.

Bleeding Index

A measure of gum health assessed by gently probing the gum pocket. Immediate bleeding indicates gum inflammation, while delayed bleeding suggests periodontitis.

Signup and view all the flashcards

Delayed Bleeding

Bleeding occurs a few seconds after the probe is inserted at the base of the gum pocket. This indicates potential periodontal disease progression and early signs of gingivitis.

Plaque & Bleeding Index Calculation

This index helps assess the severity of plaque and bleeding on teeth. It involves counting the number of teeth with plaque or bleeding and calculating a percentage.

Signup and view all the flashcards

Steps for Calculating Plaque & Bleeding Index

  1. Exclude missing teeth. 2. Count the total number of surfaces on remaining teeth. 3. Mark and count teeth with plaque or bleeding. 4. Divide the number of affected teeth by the total number of surfaces. 5. Multiply by 100 to get the percentage.

Study Notes

Full Periodontal Assessment

  • Probing Depth: Distance from gingival margin to periodontal pocket bottom.
  • Light Probing Force: 25g.
  • BPE (Bleeding on Probing Examination): Screening tool only.
  • Ball End Sizes: 0.5mm and 3.5-5.5mm.
  • Marking: 1-15mm.
  • UNC-15: Specific marking system.
  • Gingival Margin Levels: Measured from the cementoenamel junction (CEJ).
    • Natural Position: 0
    • Gingival Margin Covers CEJ: Negative value.
    • Gingival Margin Apical to CEJ: Positive value.
  • Clinical Attachment Levels (CAL): Estimate of periodontal stability and loss of support, measured from CEJ.
  • Gingivitis: Inflammation without attachment loss.
  • Periodontitis: Inflammation with attachment loss.

Furcations

  • Classification (Glickman 1953):
    • Grade 1: Probe detects just above the furcation entrance.
    • Grade 2: Probe can partially enter the furcation.
    • Grade 3: Probe passes completely through the furcation.
    • Grade 4: Same as grade 3, clinical entrance is visible.
  • Nabers Probe: Used to measure furcations.

Mobility

  • Classification (Miller 1950):
    • Grade 0: Normal mobility (0.1-0.2mm).
    • Grade 1: Slight mobility (up to 1mm).
    • Grade 2: Moderate mobility (greater than 1mm).
    • Grade 3: Severe mobility (greater than 1mm, horizontal and vertical).

Plaque Index

  • Contrast: Vegetable dye or other agents.
  • Disclosing Agents:
    • Single-Toned: Pink (plaque <24 hours), Blue (plaque >24 hours), Aqua (very acidic).
  • Disclosing Agent Types: Tablets, liquid, pre-loaded pellets.
  • Equipment: PPE, disclosing solution, cotton wool, eye protection, scribe, easy removal mechanism e.g., aspiration.
  • Important note: Use vaseline to prevent staining of the lips.

Bleeding Index

  • Immediate Bleeding: Bleeding as soon as probe is inserted.

  • Delayed Bleeding: Bleeding few seconds after probe insertion.

  • WHO probe: Used to evaluate bleeding.

  • Calculation: 4 or 6 point chart, similar to plaque index.

    • <10% Bleeding: Considered clinically healthy.
    • 10-30% Bleeding: Considered localised.
    • >30% Bleeding: Considered generalised.
