Systemic and Psychological Disease
Recognise how general and psychological conditions alter oral health, treatment risk, adherence, self-care and outcomes.
How to prepare for LDS Part 1
Build clinically applied knowledge, then practise selecting the single best safe action from five plausible options under timed conditions.
Core concepts
Concept 1
A medical or psychological condition can change diagnosis, consent support, treatment setting, drug choice, follow-up and the need for liaison.
Exam cue: Translate each comorbidity into a concrete dental risk or management adjustment.
Concept 2
The relevant question is not merely whether a condition is present, but how it changes safe dental management for this patient.
Exam cue: Account for compliance, self-care, capacity, distress and the patient's values without making assumptions.
Risk pitfalls and guardrails
Treating the medical history as background information with no effect on the plan.
Guardrail: Do not select a technically possible option if it ignores urgency, consent, medical risk, competence, follow-up or the patient's priorities.
Equating a diagnostic label with incapacity or non-compliance.
Guardrail: Do not select a technically possible option if it ignores urgency, consent, medical risk, competence, follow-up or the patient's priorities.
Memory anchors
How should a comorbidity be used in an SBA?
Link it to diagnosis, treatment risk, medicine choice, consent support or follow-up.
What patient factors can change outcomes?
Disease severity, treatment, cognition, distress, self-care, support and access.
What is the first response to psychological distress?
Recognise its effect, communicate supportively and adapt or refer safely.
Does a condition automatically remove decision-making capacity?
No. Capacity is decision-specific and must not be inferred from a diagnosis alone.
What closes the medical-risk loop?
A documented adjustment, appropriate liaison or referral, and planned review.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
