Figure 1. Preoperative view of a carious lesion on the disto-occlusal surface of a mandibular right first premolar. |
Figure 2. A glass ionomer (GI) system (Equia [GC America]) was selected as a final restorative material and shade selection was completed prior to the restorative procedure. |

Figure 3. The carious dentin was removed using No. 6 slow speed round bur and spoon excavator. The preparation design is controlled by the extent of the carious lesion with respect for maximum tissue preservation. |
Figure 4. After placement of the sectional matrix band, a conditioner (Cavity Conditioner [GC America]) was applied to the entire cavity surface for 10 seconds using an applicator tip and rinsed thoroughly. |

Figure 5. A GI cement restorative (Fuji IX GP Extra [GC America]) was injected into the cavity preparation. It is important to place the tip to the base of the proximal box and inject slowly, while removing the tip slowly. This technique prevents incorporation of voids. |
Figure 6. The material was condensed and the anatomical contours were developed using a pyramidal-shaped instrument (PKT-3A [Brasseler USA]). |
