SBI+Index


 * Sulcus Bleeding Index**

This is an assessment tool used to evaluate the existence of gingival bleeding in individual teeth and/or regions of the oral cavity upon gentle probing which allows the clinician to recognize and record early signs of inflammatory gingival disease.
 * Sulcus bleeding index description:**

Four gingival units are scored systematically for each tooth:
 * Areas examined:**
 * Labial and lingual marginal gingiva (M units)
 * mesial and distal papillary gingiva (P units)


 * Procedure:**
 * Use your lighting while probing each of the four areas
 * Hold the probe parallel with the long axis of each tooth for M units and direct the probe toward the col area for P units
 * Wait 30 seconds after probing before scoring each area
 * Dry the gingiva gently if necessary to observe color changes
 * Scoring is determined by the following:
 * score 0-for healthy appearance of P and M, no bleeding on sulcus probing
 * score 1- apparently healthy P and M, no bleeding from sulcus on probing
 * score 2 - bleeding on probing AND change in color caused by the inflammation. No swelling or macroscopic edema
 * score 3- bleeding on probing AND change in color and slight edematous swelling
 * score 4- either:
 * (a) bleeding on probing, AND change in color, AND obvious edema; or
 * (b) bleeding on probing, and obvious edema;
 * score 5- bleeding on probing and spontaneous bleeding, AND change in color, marked swelling with or without ulceration.


 * Scoring:**
 * SBI for area
 * Each of the four gingival units (M and P) is scored 0 to 5
 * SBI for tooth
 * Scores for the four units are totaled and divided by four
 * SBI for individual
 * By totaling scores for the individual teeth and dividing by the number of teeth, the SBI is determined. Indices range from 0-5

Gingivitis
 * Category-**

When gathering periodontal assessments.
 * When used-**

The operator will probe the patients teeth getting the probe into M and P unit areas. After probing wait 30 seconds to check for the scoring. The operator may have to dry the gingiva gently in order to see color changes. Then the operator will assign a number 0-5 based on the above criteria.
 * How it is used-**

Reversible
 * Reversible or irreversible?**
