Brief summary

The study will test the effectiveness and feasibility of applying silver fluoride by an Aboriginal Health Practitioner to decayed baby tooth surfaces to stop the decay process among young Aboriginal children in remote communities. The outcomes will be compared against treatments provided by dental therapists using minimally invasive approaches. the hypothesis tested is that the application of silver fluoride to decayed baby teeth will be as effective as standard minimally invasive restorative treatments in managing baby-tooth decay.

Interventions

Test participants will have silver fluoride (AgF) solution, 0.05 ml, sufficent to treat 5 teeth (38% or 40% AgF, randomly selected to receive either the 38% or 40% AgF) applied onto decayed tooth surfaces on primary molars and surfaces at risk of decay by an Aboriginal Health Practitioner. The solution will be applied using a micro-brush and applied for 60 seconds per lesion, once only. Teeth treated with silver fluoride will be further randomly allocated to receive additional application of pot

The solution will be applied using a micro-brush and applied for 60 seconds per lesion, once only. Teeth treated with silver fluoride will be further randomly allocated to receive additional application of potassium iodide (0.10 ml) applied with a micro-brush or no additional treatment. Potassium iodide will be applied until the white creamy precipitate which forms turns clear to test for the stain reducing effects of potassium iodide. The lesions will be monitored annually for 2 years and silver fluoride and potassium iodide re-applied, if necessary. Participant dental records will be reviewed for attendance and receipt of treatment.
