Direct versus indirect veneer restorations for intrinsic dental stains

The effect of bleaching, varying the shade or thickness of composite veneers on final colour: An in vitro study

“…17 This guideline also recommended that composite veneers were not generally used above the age of 16 as they tend to discolour and fracture more readily than porcelain. 18 However, a subsequent systematic review has concluded that there was insufficient evidence to produce a guideline. 18 Therefore, the choice of material for veneer use should be assessed on an individual patient basis.…”

Is the Evidence Supporting Dental Procedures Strong? A Survey of Cochrane Systematic Reviews in Oral Health

“…Yengopal et al 2009 There was insufficient evidence from the 3 included trials to make any recommendations about which filling material to use for the treatment of caries in the primary dentition I 20. Wakiaga et al 2004 There is no reliable evidence to show a benefit of one type of veneer restoration (direct or indirect) over the other with regard to the longevity of the restoration I 21. Rickard et al 2004 Given the high risk of bias in the available studies and lack of consistency between different outcome measures, there is no reliable evidence that application of ozone gas to the surface of decayed teeth stops or reverses the decay process Fabbro et al 2007 There is currently scarce evidence for a sound decision-making process among alternative treatments for re-treatment of a periradicular pathosis I RCT, randomized controlled trial; QI, quality of evidence; I, inadequate; A, adequate.…”
