Clinical Performance of Adhesive Systems and Composite Resins in Restoration of Noncarious Cervical Lesions: Systematic Review of Randomized Clinical Trials from 2004 to 2014

The aim of the present study was to compile a systematic review of the best available evidence on the clinical performance adhesives and composites used for the restoration of noncarious cervical lesions. Several electronic databases such as Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline and Embase were interviewed. In addition, some studies were identified by hand searching. Thus randomized controlled trials comparing at least two adhesives or two composite resins with at least 12 months follow-up were selected. Criteria for quality assessment included: random sequence generation; allocation concealment; blinding of outcome assessment; and information on withdrawals. Two hundred and fifty eight writings were found by the search strategy, but only 8 articles were finally selected. These studies demonstrated a good clinical performance for the four accession strategies and evaluated the different composite resins. However, they showed great variation between the adhesives of the same category. Thus, subject to the design and the quality of studies included in this systematic review, we can conclude that there is not enough evidence to support the superiority of an adhesive or a composite resin to another for the restoration of non-carious cervical lesions.
