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, the region's COHI team identified the need to provide a caries control procedure like that of atraumatic restorative treatment (ART), which is provided by COHI Health Canada dental therapists in all regions other than Ontario and Quebec.

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 these minimally invasive dental treatment procedures that are within the dental hygiene scope of practice. The rationale for offering these types of interventions, to which client groups, and in which settings will be discussed along with an introduction to their combination and compatibility. The theory behind silver diamine fluoride and glass ionomer temporary restorations will be covered in detail.

Following the theory portion of the workshop, there will be an opportunity to practise the procedures for placing IST restorations using hand-mixed glass ionomer cement. All supplies will be provided.

Learning Objectives:

After attending the session, participants will be able to:

  • Understand the history of ART and the evolution of IST in Ontario
  • Describe the clinical differences between ART and IST
  • 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
  • Understand the compatibility and indications for using a combination of SDF and IST interventions
  • Document the dental hygiene care provided
