Class I Cavity: Restorations with Composite Resin

Class I Composite Restorations

These include pits and fissures that can be easily, quickly, and esthetically restored by composite resins. As an added bonus, the bonding of small grooves, defects, or pits in individual teeth is an excellent means of preventing either initial or further caries with little or no risk of tooth discoloration as the case may be with amalgam.

When matching an exact shade is important to your patient, be sure to make your shade selection before placing a rubber dam. In the event the tooth is discolored due to an old amalgam restoration, it may be necessary to remove the amalgam first—then make your color selection.

Use a “stock” shade guide supplied by the manufacturer only to select several of the closest shades with which to do your actual shade trial bonding. To achieve the closest match, remove all of the old restorative material plus any stained tooth surface that might mar your esthetic result. Have all your materials ready, including a mylar strip and GCI#3 (Hu-Friedy). Place a small amount of composite resin on the tooth to be matched. Quickly apply the mylar strip using more pressure on one end of the composite so you will achieve a good range of color from thick to thin on the labial surface after polymerization. Then let the tooth regain its moisture until its normal color has returned. Make your shade comparison as quickly as possible, avoiding any long periods of tooth desiccation.
