170 - Speed Learning, Back to Basics: Restorative Principles & Materials

There are many tried and true approaches and materials used to manage the diverse restorative needs of pediatric dental patients. Composite resins and glass-ionomer cements were introduced over 50 years ago and since then modifications to both materials, as well as newer versions (e.g., bioactive) claiming intermediate properties are now available. These changes coupled with multiple adhesive strategies can lead to confusion regarding materials and selection problems. While these materials are tooth-colored, there is a considerable difference in their properties, and it is important that each is used appropriately. Composite resin materials are esthetic and now show acceptable physical strength and wear resistance. However, they are hydrophobic, and therefore more difficult to handle in the oral environment and cannot support ion migration. On the other hand, glass ionomers are water-based and therefore have the potential for ion migration, both inward and outward from the restoration, leading to several advantages. However, they lack the physical properties required for use in load-bearing areas. This presentation is intended to update the classification, material selection, and material application so that clinicians can make appropriate and evidence-based choices when selecting restorative materials. We will discuss materials for both direct and indirect restorations, treatment options and the advantages and disadvantages of various techniques. The evidence related to different restorative approaches and reported clinic outcomes will be reviewed. Cases illustrating digital workflows for restorative care of both anterior and posterior teeth will be presented providing information that you can adopt in your pediatric dental practice.
