Abstract
OBJECTIVE: To investigate the influence of the selective etching in the survival rates of indirect restorations cemented with self-adhesive resin luting. MATERIALS AND METHODS: The eligibility criteria were formulated based on PICOS strategy. The search without restrictions was performed in PubMed/Medline, the Cochrane Library, Web of Science, Scopus, LILACS databases and gray literature until May 2018. Cochrane Collaboration's tool was performed for assessing the risk of bias. According to the bias risk analysis, the studies were classified as low risk of bias and high quality of evidence. The systematic review was conducted according to PRISMA and registered in PROSPERO (CRD42018091202). The meta-analysis was performed using RevMan 5.3 software (RevMan, Copenhagen, Denmark) and the risk ration and confidence interval was obtained (p < 0.05). RESULTS: After database screening, removal of duplicates and eligibility criteria application, two studies were selected for this systematic review, with 65 participants (34 in one and 31 in the other). The pooled meta-analysis demonstrated no statistically significant difference in clinical longevity for selective etching in indirect restorations (P > .05; I2 = 0%) and risk ratio of 0.46 [0.19-1.09]. CONCLUSIONS: Based on the findings, the results of this systematic review suggest that the selective enamel etching prior to application of self-adhesive luting cements systems for indirect restoration do not influence the clinical longevity of indirect restorations. CLINICAL SIGNIFICANCE: The knowledge of the clinical steps of adhesive procedures is fundamental to the success of adhesive restorations and their longevity. Self-adhesive resin cements simplify the luting procedure of indirect restorations. However, adding a step that could significantly improve long-term survival would be of great value. Thus, the results of this systematic review will provide data so that the decision making regarding materials used for adhesive cementation is conducted based on scientific evidence.
