When is it assigned?
After diagnostic assessment.
← All explanationsPeriodontitis staging
What does stage II or III periodontitis mean?
Staging assigns diagnosed periodontitis to stages I to IV. It describes accumulated tissue loss and complexity of care. It is not simply a pain scale or an automatic decision about individual teeth.

Record accumulated damage
Findings include attachment and bone loss and teeth lost because of periodontitis. Other reasons for missing teeth must be distinguished.
Consider complexity
Deep pockets, furcation involvement and functional problems can complicate care. Stage IV includes complex situations, such as impaired chewing function.
Plan beyond initial treatment
Stage informs treatment and maintenance. It is not simply reduced after successful treatment because the disease history remains relevant.

Often confused
Staging versus grading
Staging concerns accumulated damage and complexity of care. Grading adds an assessment of progression.
Quick answers
Does stage III mean losing every tooth?
No. Stage describes the case, not a certain outcome for each tooth. Individual tooth prognosis requires separate assessment.
Is stage the same as grade?
No. Stage concerns severity and complexity; grade estimates progression.
Why keep the stage after improvement?
Previous tissue loss and complexity still influence ongoing care. Clinical improvement remains possible.

Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Which findings determine my stage, and how do they affect my care?
Understanding the stage can make the next steps clearer.
