Non-restorative caries care packages these with diet counselling, professional plaque removal, fluoride varnish and, where sealing is more practical than cleaning, the Hall technique and atraumatic restorative treatment — a medical management serving young children avoiding general anaesthesia, special-needs patients and the elderly with root caries. ## What you must remember - The philosophical shift: from the surgical model (every cavity is filled) to the medical model (the disease is treated, the lesion is arrested) — frameworks such as ICCMS and CAMBRA formalise risk assessment and lesion-activity decisions. - Silver diamine fluoride: 38 per cent solution, applied twice yearly, commonly arresting around 70-80 per cent or more of active lesions; arrests stain black (consent is essential); avoided on ulcerated mucosa and in silver allergy; painless, quick and ideal where cooperation is limited. - Toothbrushing is the treatment: supervised twice-daily brushing by an adult, with lesions physically brushed clean — arrest is impossible where plaque sits undisturbed on the cavity floor — supported by 5 per cent sodium fluoride varnish (22,600 ppm) every three to six months. - Non-restorative cavity control: cavities are opened and edges smoothed so the brush can reach the base, converting an uncleanable lesion into a cleanable one without restoration. - The Hall technique: preformed metal crowns cemented with glass ionomer over carious primary molars without any caries removal — sealing arrests the lesion, with trial evidence at least matching conventional care; unsuited to teeth with pulpitis signs. - Atraumatic restorative treatment: hand excavation of softened caries and high-viscosity glass ionomer placement — the WHO-endorsed community technique where electricity and rotary instruments are unavailable, and still a legitimate minimal-intervention option anywhere. - Boundaries: pulp involvement, swelling, sinus or pain convert the plan to restorative or surgical care; lesions the family demonstrably cannot clean also fail non-restorative management. - Monitoring is definitive: activity is re-assessed at recall by texture, colour and margins — arrested lesions are hard, dark and shiny. ## Building a plan for a family refusing GA A four-year-old presents with multiple active lesions across molars and upper incisors; the parents decline general anaesthesia after counselling. The plan is layered. Session one is prevention: diet diary and counselling (frequency of sugars, no sweetened bottle at night), supervised brushing coaching with the parent's hand on the brush, 1000 ppm fluoride toothpaste twice daily, and fluoride varnish applied to every lesion. Session two applies 38 per cent silver diamine fluoride to the active cavitated lesions, after explicit consent for the black staining it produces. Cavities too deep for brush access are opened for cleaning and their sharp edges smoothed; one molar with sound margins but deep caries is managed with a Hall crown cemented with glass ionomer, sealing the lesion beneath. Two pulp-threatening lesions are restored with ART-style hand excavation and glass ionomer. Recall at one and three months checks brushing quality — the actual engine of arrest — and re-varnishes at three to six months. The lesions that arrest are hard and dark; the family that brushes has converted an operation into a habit, which was always the better trade. ## Where students slip The framing error comes first: calling non-restorative care "no treatment" or "watchful waiting" — it is active treatment with defined agents, techniques and review intervals, and the viva punishes the distinction. The second is consent: the SDF conversation must name the black staining before the first drop is applied, since aesthetics is the technique's only frequent casualty. The third is boundary-keeping — SDF and the Hall technique applied to a tooth with pulpitis signs delays necessary pulp care and damages trust. Finally, know the Hall technique's mechanism (sealing, not excavation) and ART's definition precisely — both reduce to one-line differentiators in examinations. ## Frequently asked questions ### What is silver diamine fluoride and its arrest rates? A 38 per cent solution applied twice yearly, arresting commonly 70-80 per cent or more of active lesions, staining arrested dentine black. ### What is the Hall technique? A preformed metal crown cemented with glass ionomer over a carious primary molar without caries removal; the seal arrests the lesion. ### How does non-restorative cavity control work? The cavity is opened and margins smoothed so the brush reaches the base — a stagnant lesion becomes cleanable and arrests. ### When is non-restorative care inappropriate? Pulpal involvement, pain, swelling or sinus; lesions the family cannot clean; informed families preferring restoration. ### What distinguishes an arrested lesion? Hard, dark, glossy surfaces with smooth margins — active lesions are soft, matt and plaque-covered. ### What is atraumatic restorative treatment? Hand excavation restored with high-viscosity glass ionomer — the WHO-endorsed community and field technique.
