The following conclusions can be made: A glass ionomer cement mixed in preweighed capsules to restore anatomically deficient cervical contours demonstrated bonding of the total restoration to tooth tissue without undercutting or pinning the tooth or relying on geometric design of a cavity preparation in approximately 95% of 113 restorations observed postoperatively for six months. Seven restorations showed partial loss of material. Seven of the 113 restorations, showed some marginal discoloration although no stain penetrated the interface of the tooth and restoration. For most cervical restorations, the glass ionomer cement produced a mismatch in "color, shade, and/or translucency" in relationship to the tooth. The probable reason for this is the opacity of the cement. An acceptable surface of the glass ionomer cement restorations can be established at a later finishing appointment. There is little evidence that roughness increased slightly during the six months. Patients' sensitivity to temperature and direct tactile contact diminished or was eliminated after placement of the restoration.
