“…Studies involving Clearfil SE Bond, a self-etching adhesive, showed that this material provided greater bond strength than other types of adhesive systems. The authors attributed those results to the presence of 10-MDP (18,23). Clearfil SE Bond, unlike Single Bond Universal, is a two-step system.…”

“…Water absorption has a negative effect on composite restoration, causing a reduction in resistance to wear, residual monomers and hydrolytic degradation of chemical reactions (17). According to some authors, the highest water absorption occurs in the first week, and in up to two weeks, it is still possible to obtain chemical adhesion of new composite increments due to the presence of free radicals available in the old composite (18).…”

Repair bond strength of bulk fill composites after different adhesion protocols

Background: Repairs in composite resin restorations are common procedures in clinical practice. Many surface treatment options have been proposed to improve the adhesion between the old and new composite. The objective of this study was to evaluate the microtensile bond strength of repairs performed on aged bulk fill and conventional composites after different adhesion protocols. Material and Methods: First, 84 specimens (8x8x4 mm 3 ) of a microhybrid composite and a high-viscosity bulk fill composite were prepared and aged. Afterward, they received a mechanical surface treatment by means of abrasion with a diamond bur, followed by division into six groups according to the adhesion protocol employed: PSAetching with 35% phosphoric acid + silane + etch-and-rinse adhesive; SA -silane + etch-and-rinse adhesive; PA -etching with 35% phosphoric acid + etch-and-rinse adhesive; A -etch-and-rinse adhesive; PU -35% phosphoric acid + universal adhesive; and U -universal adhesive. The repairs were performed with a microhybrid composite. Repaired resin blocks were cut into sticks (8x1x1 mm 3 ) and submitted to a microtensile test. Fractured specimens were evaluated to determine the failure pattern (adhesive or cohesive). Data were analyzed by two-way ANOVA. Results: No statistically significant differences were found in bond strength values among different adhesion protocols and composite types. Conclusions: The repair bond strength of a bulk fill composite was similar to that found in a conventional composite, with no distinction among adhesion protocols.

“…In the no water storage groups, BE2 and APX, there were no significant differences in µSBS between with and without the application of one-step selfetch adhesive (Clearfil SE One). The application of an adhesive agent could improve the surface wettability on the cured-composite and enhance monomer diffusion into the cured-composite, leading to an increase in repair bond strength 20) . However, in the no waterstorage group, the existence of un-reacted monomers in the cured-composite would not require the diffusion of further additional monomers with adhesive application into the cured-composite to obtain composite-composite adhesion.…”

“…Clearfil SE One contains the hydrophilic monomer, HEMA. Therefore, adhesive application could enhance monomer diffusion into the water-aged cured-composite with few unreacted monomers and improves surface wettability for application of the hydrophobic composite 20) .…”

The repair bond strength to resin matrix in cured resin composites after water aging

et al. 2019

The repair microshear bond strengths (µSBSs) to resin matrices in 4 different cured-composites after water storage (0, 60 s, 1 week, 1 month) were evaluated. Three different adhesive application methods to the cured-composites were performed; (1) none, (2) onestep self-etch adhesive application, and (3) one-step self-etch adhesive application with a silane coupling agent. Degree of conversion (DC) of the composite discs was determined using ATR/FT-IR with a time-based spectrum analysis. Initially, the amount of unreacted resin monomers in the repaired cured-composite contributed to the bonding performance of newly-filled uncured-composite to resin matrix of the cured-composite. Adhesive application could not improve their repair µSBS. After 1-month of water-storage, the repair µSBS was dependent on material, which either reduced or did not and was not influenced by their amount of un-reacted resin monomers. When repairing aged composite resin, the appropriate adhesive application procedures were different among resin composites.

“…The success of these procedures mainly depends on the composite resin adhesion to the artificial teeth [7]. Various methods have been reported to improve the reactivity of highly converted composites; these methods include acid etching [9], air abrasion [10] and the use of adhesives [11]. There is no consensus on the results obtained with the different procedures.…”

Effect of surface treatments on the bond repair strength of resin composite to different artificial teeth

Full arch prosthesis is one alternative to rehabilitate edentulous patients. This prosthesis consists of artificial teeth mounted on a mucus supported acrylic resin base with the purpose to restore aesthetics, phonetics and mastication [1]. During chewing, the stresses induced in the denture may cause injury to the support tissue, if equilibrium conditions suitable for occlusal adjustment are not created [2]. The most common material used for artificial teeth is acrylic resin with acceptable mechanical properties and
