Minimum intervention oral care: staging and grading dental carious lesions in clinical practice

Developmental staging of carious lesions is pivotal for appropriate ethical clinical decision-making in contemporary caries management. Accurate assessment of lesion extent/severity (staging) and activity (grading) allows practitioners to provide the most appropriate preventive advice and suitable interventions, enabling the implementation of evidence-based, person-focused, prevention-based, team-delivered and susceptibility-related phased minimum intervention oral care. Minimally invasive dentistry remains an important operative interventive option for cavitated lesions, but intervening at the right stage ensures patients are not started on an irreversible, destructive restorative cycle unnecessarily. This article provides an update on recommended practical methods for staging the extent/severity and grading the activity of dental carious lesions, especially for those clinical teams delivering primary care and needing to navigate remuneration systems.
