Two year clinical evaluation of a low-shrink resin composite material in UK general dental practices

Three-year Clinical Evaluation of Different Restorative Resins in Class I Restorations

“…Satisfactory clinical performance was reported with a rate of 84% optimal for marginal integrity and 77% for marginal discoloration at the end of two years. 8 At the two-year and three-year recalls, respectively, Filtek Silorane received 73% and 50% Alpha scores in marginal discoloration and 56% and 45% Alpha scores in terms of marginal adaptation.…”

“…7 Many laboratory studies have addressed bond strength of silorane-based restorative on tooth structure; however, it is of paramount relevance to study the clinical behavior of silorane restorative resin, as information about the clinical performance of this restorative is very limited. [8][9][10][11][12] Moreover, the results of these in vitro studies cannot always be directly extrapolated to the performance of restorative materials.…”

<sup>99m</sup>Tc in the evaluation of microleakage of composite resin restorations with SonicFill<sup>TM</sup>. An <i>in vitro</i> experimental model

“…Despite having good physical properties, the main shortcomings of composite resin materials are polymerization shrinkage [1][2][3][4][5][6][7][8] and polymerization stress [5]shrinkage stress resulting in internal microcracks within the bulk of the material [7]; separation of the bonding agent from the cavity wall with resultant gap formation, marginal microleakage and post-operative sensitivity [1,3,[7][8][9]; enamel microcracks [5,7]; marginal staining [8]; wear [9]; discoloration [9]; lower fracture resistance [1,5,9]; recurrent caries [1,3,8,9]; and deformation of tooth [5,7].…”

Effect of Using Silorane-based Resin Composite for Restoring Conservative Cavities on the Changes in Cuspal Deflection

“…The cationic ring opening of oxirane moieties in the silorane-based composite yields a reduced volumetric shrinkage 21,22 in contrast to the free radical addition reaction of the double bonds of the dimethacrylate-based composite. 4,7,23 When acidic cations attack the oxirane rings, the cleavage and opening of these rings gain space, thus counteracting the loss of volume occurring in the subsequent step when covalent bonds are formed. 7 The lower shrinkage of silorane-based material due to its alternative resin formulation was confirmed by other authors.…”
