The periodontal probe is used to:
The periodontal probe is used to:
*Measure periodontal probing depth
*Measure [[Dental Indices and Criteria#Periodontal Probing Depth (PPD)|periodontal probing depth]]
*Determine degree of gingival inflammation by gentle probing
*Determine degree of gingival inflammation by gentle probing
*Measure gingival attachment loss (recession)
*Measure [[Dental Indices and Criteria#Gingival Recession|gingival attachment loss (recession)]]
*Evaluate furcation lesions
*Evaluate [[Dental Indices and Criteria#Furcation Involvement|furcation lesions]]
*Evaluate extent of tooth mobility
*Evaluate extent of [[Dental Indices and Criteria#Tooth Mobility|tooth mobility]]
The markings on the probe are either engraved rings or colour coded bands. A screening probe for example has 3 or 4mm banded block markings whilst a Williams periodontal probe is more accurate with mm markings. Before using the probe, the operator should ensure that they know what the markings represent by comparing the probe to a ruler.
