OHDR PERIODONTAL™
Learn how periodontal findings interact with systemic and behavioural context
Periodontal complexity is more than a pocket measurement. This module teaches how findings, systemic context, behaviour, medications, treatment phases and supportive care connect into structured clinical reasoning.
Learning areas
Tissues, biofilm, host response and what a periodontal assessment is for.
Recognising inflammation and distinguishing it from attachment loss.
Attachment loss, pattern, extent and the meaning of unresolved findings.
How stage, grade and extent are reasoned by a clinician — never from one number.
Tobacco, adherence, stress and self-care capacity as modifiable clinical factors.
How diabetes, cardiovascular and immune context interact with periodontal findings.
Why medication groups matter for bleeding, immune and healing reasoning.
Mucositis, peri-implantitis and maintenance-dependent outcomes.
Risk-factor control, active care, reassessment and supportive care.
Comparing records and reasoning about response.
Individualized intervals, adherence and recurrence signals.
When and why another professional must be involved.
Fictional educational cases for structured reasoning.
Versioned evidence entries linked from the module.

How the factors interact
Each interaction category below maps onto an existing OHDR Clinical Risk Domain™. Learning to name the domain is part of learning to reason.
- · Diagnosis context
- · Plaque / biofilm profile
- · Tobacco context
- · Diabetes context
- · Patient education
- · Modifiable factors
- · Professional-selected interventions
- · Sites
- · Dates
- · Response
- · Unresolved findings
- · Previous measurements
- · Current measurements
- · Stability
- · Response
- · Residual pockets
- · Unresolved concerns
- · Individualized maintenance
- · Adherence
- · Recurrence signals
- · New medical context
- · Review triggers
- · Next review date
No universal maintenance interval is appropriate for all patients. The interval is individualized and documented by the responsible clinician.
Stage and Grade are clinician-entered classification context with the clinician's rationale. OHDR never infers a stage or grade from a single measurement.
Educational case library
All cases are fictional and created for education. They never represent real patients and never produce a professional clinical output.
- · Widespread bleeding on probing recorded
- · Plaque distribution recorded
- · No attachment loss recorded
- · Full probing chart
- · Self-care routine detail
- · Date of last professional cleaning
- · Irregular self-care
- · Irregular attendance
- · High stress period reported
- · None required — periodontal context owns this case.
- · Not indicated at this stage; risk-factor control and re-measurement come first.
- · Inflammation after a documented period of supported self-care.
Inflammation without recorded attachment loss belongs in risk-factor control. The learning point is that a pathway can be structured only after the missing measurements exist.
Structured reasoning & knowledge checks
- 1. What information is available?
- 2. What information is missing?
- 3. Which factors may modify the clinical context?
- 4. What additional information would you want?
- 5. Which existing OHDR module may be relevant?
- 6. Why might coordination be required?
- 7. What would you reassess?
- 8. How would you explain your reasoning?
- · Reading a single pocket depth as a diagnosis.
- · Assuming reduced bleeding in a person who smokes means improvement.
- · Inferring stage or grade without radiographic or historical evidence.
- · Blaming the patient instead of documenting a modifiable factor.
- · Treating a universal maintenance interval as appropriate for everyone.
- · Proceeding to restorative or implant planning before periodontal stability is documented.
