Interim stabilization therapy (IST) is a temporary restorative procedure introduced by the Ontario Region First Nations and Inuit Health Branch, Children's Oral Health Initiative (COHI) in August 2010. IST may also be applicable to a much broader population who have limited access to care including adults and the elderly.

IST is an evidence-based therapeutic intervention that preserves the tooth structure and prevents pain and premature loss of teeth due to decay. The IST technique requires no anaesthetic and uses a fluoride-releasing material known as glass ionomer cement (GIC) to prevent further damage to the tooth from decay until the client can be seen by a dentist. IST can be performed easily at the time of assessment on individuals of all ages with minimal supplies. IST is a critical, timely intervention to prevent pain and infection.

Silver diamine fluoride (SDF), approved for use as a caries control agent by Health Canada, can be used in combination with glass ionomer cement. Caries control procedures such as SDF and IST are important for those who do not have regular access to oral health services as they help to prevent further tooth damage and additional health problems arising from untreated decay.


During this hands-on workshop, participants will learn about minimally invasive dental treatment procedures within the dental hygiene scope of practice. The theory behind silver diamine fluoride (SDF) and glass ionomer temporary restorations will be covered in detail. Following the theory portion, participants will have an opportunity to practise the procedure of placing interim stabilization therapy (IST) restorations using hand-mixed glass ionomer cement (GIC). All required supplies will be provided.

Learning objectives

After attending the session, participants will be able to:

  • Discuss the history of atraumatic restorative treatment and the evolution of IST in Ontario
  • Describe the effectiveness of GIC and SDF in caries control
  • Explain clinical indications and contraindications for the application of IST and SDF
  • Apply the clinical protocol for IST and SDF
  • Demonstrate the application of GIC on a model
