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 similar to 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 which 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), which prevents further damage to the tooth from decay, until such time as 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.

Caries control procedures such as IST are important for those who do not have regular access to oral health services as they provide immediate care, reducing further damage and preventing additional health problems.

Learning Objectives:

After attending the orientation session, participants will be able to:

  • Understand the history of ART and the evolution of IST in Ontario.
  • Reference the research and documentation that support the procedure and products used to provide IST.
  • Describe the clinical differences between ART and IST in relationship to the College of Dental Hygienists of Ontario's (CDHO) dental hygiene scope of practice.
  • Assess clinical indications and contraindications for the application of IST
  • Apply the clinical protocol for IST
  • Provide appropriate documentation as required by dental hygiene process of care and CDHO guidelines
  • Mix and apply glass ionomer cement as indicated to temporarily control caries
