Periodontal Disease Staging and Grading (2017 Classification)
Classifies periodontitis severity (stage) and progression rate (grade) to guide treatment complexity and prognosis
- Highest activation tier
- Mandatory
- How it is scored
- Scored in code; a stated value is compared only from the structured summary or a supplied value
- Scoring type
- classification
- Care settings
- Outpatient
When it activates
Scribeable activates a calculator from the encounter. The Periodontal Disease Staging and Grading (2017 Classification) can activate when the transcript or pasted chart context documents any of these:
- Periodontal disease classification
- Periodontitis staging
- Periodontal treatment planning
- Gum disease severity assessment
- Periodontal prognosis evaluation
A coded diagnosis can also activate it. ICD-10 prefixes carried by the registry: K05.3, K05.4, K05.5.
Note-type scope: it activates on notes whose subject resolves to dental. A note that resolves to another subject does not carry it even when the clinician's specialty matches; a note with no resolvable subject (a generic consultation) falls back to the specialty match.
Inputs the note needs
2 inputs. Each is resolved from the transcript, the pasted chart context and charted labs; an input marked "asks you" is requested as a clarification when it is undocumented.
| Input | Type | Unit / options | Guidance |
|---|---|---|---|
| Periodontal stage (1-4): based on clinical attachment loss, radiographic bone loss, tooth loss due to periodontitis, and case complexity | exam | ||
| Periodontal grade (A, B, or C): rate of progression based on direct/indirect evidence and risk factor modification | exam |
Scoring
Stage I: Initial — CAL 1-2mm, bone loss coronal third (<15%), no tooth loss. Stage II: Moderate — CAL 3-4mm, bone loss coronal third (15-33%), no tooth loss. Stage III: Severe — CAL >=5mm, bone loss extending to mid/apical third, <=4 teeth lost. Stage IV: Advanced — CAL >=5mm, bone loss extending to mid/apical third, >=5 teeth lost, masticatory dysfunction. Grade A: Slow progression (<0.25mm/year bone loss). Grade B: Moderate (0.25-1.0mm/year). Grade C: Rapid (>1.0mm/year or specific risk factors like smoking, diabetes).
Interpretation
Stage I-II: Non-surgical therapy (scaling and root planing) usually sufficient. Stage III: Surgical therapy often needed (flaps, regeneration, implants). Stage IV: Complex rehabilitation — multidisciplinary approach, possible full-mouth reconstruction. Grade A: Stable, routine maintenance sufficient. Grade B: Standard risk, 3-4 month recall. Grade C: High risk — aggressive management, smoking cessation, diabetes control essential, 2-3 month recall. Staging determines complexity; grading determines urgency and prognosis.

How Scribeable handles it in the note
When an encounter activates the Periodontal Disease Staging and Grading (2017 Classification) at the mandatory tier, Scribeable resolves its inputs from the transcript, the pasted chart context and any charted labs, and asks you for a missing input you can supply before the note is finalised. Bedside-exam and separately ordered study values are not requested one input at a time; a calculator that carries a combined clarification question may still put that single question to you.
The score is computed in code from the resolved inputs, not recalled by the language model. A stated Periodontal Disease Staging and Grading (2017 Classification) value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.
Classified as a staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
