Brief summary

The primary aim is to determine, over a 12 month period, the relative dental caries (tooth decay) arrest and prevention abilities on the primary teeth of children aged one to eight years of a once-only treatment of 38% silver diamine fluoride, compared to three-monthly applications of 5% sodium fluoride varnish in the Tasmanian clinical situation. The secondary aims are to compare: 1/ The dental caries prevention and arrest abilities of once-only treatments of silver diamine fluoride, silver diamine fluoride/potassium iodide, and silver diamine fluoride/potassium iodide/glass ionomer fissure sealant . 2/ The effectiveness as measured by relative cost, patient and clinician acceptability of treating tooth decay on the primary teeth of children of silver diamine fluoride, silver diamine fluoride/potassium iodide, silver diamine fluoride/potassium iodide/glass ionomer fissure sealant, and the standard dental treatment of restorations and extractions as determined by calibrated dentists if it were feasible to do the care under local anaesthetic.

Interventions

All treatments will be undertaken by an oral health therapist and applied using a micro brush at the time of entering the study. There will be three treatment groups (and one control group): 1/ A once-only treatment of 38% silver diamine fluoride, 2/ A once-only treatment of 38% silver diamine fluoride followed by an application of potassium iodide. 3/ A once-only treatment of 38% silver diamine fluoride followed by an application of potassium iodide then covered by a glass ionomer fissure seal

All children will also receive three-monthly oral health promotion in twice daily tooth brushing with a fluoride-containing toothpaste.
