Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationPatients with permanent anterior teeth suitable (i.e. with intrinsic staining) for restorations using laminate veneers112 patients (180 restorations) with permanent maxillary anterior teeth requiring 1 to 6 veneers (maximum 2 included per patient); mean age 30 years (range 14 to 74); recruited via general practitioners and the Dental School, University of Nijmegen, The Netherlands
InterventionDirect laminate veneer techniques (different composite materials)Direct resin composite (microfine; Silux Plus) (n=69 restorations); Indirect resin composite (microfine; Dentacolor) (n=54); Porcelain (fine crystalline; Flexo-ceram) (n=56)
ComparisonIndirect laminate veneer techniques (indirect restorations composite or porcelain)Not reported (three-arm trial; comparator arms not separately defined)
OutcomesRestoration failure (primary; debond, fracture, delamination or significant leakage requiring replacement); Aesthetic achievement (colour match); Patient satisfaction (e.g. visual analogue scale); Pain following treatment; Cost of treatment; Adverse reactionsAbsolute failure (n=180 restorations); Relative failure (n=180); Survival of original restoration (n=180); Functional survival (n=180); Overall survival (n=180); Patient satisfaction (n=112 patients)
Study designsRandomised controlled trials (RCTs); quasi-randomised trials eligible (sensitivity analysis)1 RCT (Meijering 1998; three publications; 2.5-year interim analysis; The Netherlands)
TimingNot specifiedBaseline (~4 weeks post-placement); ~1 year (0.9 to 1.3 years); 2 years (1.9 to 2.5 years)
