“…The results from this study are consistent with those of Krifka et al [31], who analyzed microleakage in class V comparing methacrylates and siloranes. They observed that silorane-based composites exhibited the best marginal seal.…”

Self-etching adhesive (SEA) systems were recently introduced to simplify the bonding procedure, reducing the number of operative steps, and were initially considered a good replacement for the etch-and-rinse adhesive system that uses orthophosphoric acid (H₃PO₄) (PA) for enamel and dentin etching [1]. However, the recent literature underlines that the effectiveness of the enamel bonding with SEA is questionable [2]. This technique in fact provides a bond strength of compos- AbstractBackground. Self-etching adhesive (SEA) systems were recently introduced to simplify the bonding procedure and were initially considered a good replacement for the etch-and-rinse adhesive system that uses orthophosphoric acid (PA) for enamel and dentin etching. Siloranes, a new class of ring opening monomers, were synthesized to overcome the problems related to polymerization shrinkage. This new type of monomer is obtained from the reaction of oxirane and silorane molecules with a volumetric shrinkage determined to be 0.99%. Objectives. To assess the influence of preliminary phosphoric acid etching on the sealing ability of silorane-and methacrylate-based composites. Material and methods. Standard class V cavities were prepared on the buccal side of 48 extracted, sound, human premolars. The specimens were randomly divided in two groups: A) Silorane System ® /Filtek Silorane ® ; B) Scotchbond Universal ® /Filtek Supreme ® . Each group was divided in two subgroups. A1) and B1): no preetching was performed. A2) and B2): selective, enamel pre-etching was performed. The interfacial sealing ability of the materials was evaluated by scoring the depth of methylene blue penetration through optical microscope observations. The differences in infiltration scores recorded for the tested materials were evaluated for statistical significance (Kruskal-Wallis ANOVA, Mann-Whitney U test, p < 0.05).Results. No groups showed a "0" score, and group B2 had the lowest individual score, reaching at least a "2" score.In the silorane groups, pre-etching decreased the infiltration score but the result was not statistically significant. No statistically significant differences emerged among the tested materials except for the Bis-GMA composite restored group where the pre-etching significantly reduced the interfacial leakage (p < 0.05).Conclusions. Selective enamel pre-etching significantly reduced the marginal infiltration in class V cavities, restored with Bis-GMA composite and a self-etching adhesive system. The low-shrinking silorane composite achieved better sealing ability (Dent. Med. Probl. 2016, 53, 3, 365-372).

“…Use of lasers for cavity preparation has not shown any improvement in microleakage sealing when compared to the conventional diamond bur preparation, highlighting the importance and need of suitable restorative material [26]. The use of silorane based composites has also been suggested for restoration of class V cavities in a recent study [27].…”

“…Numerous studies show that even when attempting to bond the material to a cavity preparation, the marginal seal is typically compromised, resulting in marginal gaps, stains, or leakage [49,50]. This deficiency remains true even with current "improved" adhesive systems [51][52][53]. In fact most in vitro leakage studies have shown that dental composites do not provide a perfect seal to either enamel or dentin, independent of bonding or placement method [54].…”
