Evaluation of the Sealing Ability of Direct versus Direct-Indirect Veneer Techniques: An In Vitro Study

Figure 6

Tooth samples demonstrating dye penetration along the laminate-tooth interface at the gingival margin. (a) One sample from group A, subgroup 1, when using nanohybrid composite with direct veneer technique. (b) One sample from group A, subgroup 2, when using microfilled composite with direct veneer technique. (c) One sample from group B, subgroup 1, when using nanohybrid composite with direct-indirect veneer technique. (d) One sample from group B, subgroup 2, when using microfill composite with direct veneer technique.
