Tooth related criteria: - Deciduous teeth; as the study was targeting only permanent teeth. - Teeth with previous restorations, which might add another variable to the study (type of old restorative material, extent of recurrent caries). This could also affect the bond of laminate veneers to tooth structure. - Patients with parafunctional habits, large restorations, or excessive tooth wear. - Initially, scaling and polishing was performed. Patients were instructed on improving their oral hygiene and maintaining effective plaque control. However, if their gingival health did not improve, they were excluded from the study. |

Primary | Survival of laminate veneers using modified USPHS | Patients were called back after 1 week as the baseline to assess the veneer restorations. Assessment was carried out by an experienced observer blinded to the assigned study group for each patient. Laminate veneers were examined at baseline, after 3, 6 and 12 months according to the modified United States Public Health Service (USPHS) criteriae and the USPHS scores of Alfa, Bravo and Charlie were used for rating . Patients were also questioned about possible post-operative complaints. Digital photographs were made after placement of the veneers and during follow-up sessions. | 1 year |
