Interim Stabilization Therapy (IST) is a temporary restoration procedure and an important therapeutic
intervention that is used to free a client from pain and prevent further damage to a tooth until the client can
get the tooth addressed by a dentist. IST requires no anaesthetic and uses a fluoride-releasing material known
as glass ionomer cement. The fluoride in the glass ionomer cement helps to remineralize the affected lesion.
In IST the affected tooth is prepared by removing any soft debris (plaque and/or food particles) from the lesion.
A conditioner is then added and a glass ionomer is placed in accordance to the manufacturer’s instructions.
