“…The results of the studies indicate that the application of adhesive agents under amalgam restoration helps prevent microleakage (33,34). The SEM images show that the adhesion between the amalgam and the adhesive is mechanical and forms as a result of the amalgam's interlacing with the adhesive material protruding into the amalgam (35). In the current study, no significant effects were observed on the surface morphology of Panavia F and Amalgambond Plus from interactions with amalgam.…”

Aim: The purpose of this study was to evaluate the effectiveness of different adhesive systems in amalgam restorations and their effects on microleakage. Methodology: In this study, 105 caries-free extracted human permanent molar teeth were used. Teeth were randomly assigned to five groups (n=21), and class I cavities were created on the surface of each tooth. The first was a control group to which no adhesive system was applied. Amalgam Liner (VOCO GmbH, Cuxhaven Germany) was applied to Group II, Clearfil SE-Bond (Kuraray Europe GmbH, Frankfurt Germany) was applied to Group III, Panavia F 2.0 (Kuraray Europe GmbH, Frankfurt Germany) was applied to Group IV, Amalgambond Plus (Parkell Inc.Edgewood, NY USA) was applied to Group V, and then amalgam (Tytin, Kerr, California USA) restorations were placed. After the polishing process, samples were subjected to thermocycling 1,000 times. Teeth were sectioned bucco-palatinally/lingually, and microleakage scores of the occlusal walls were evaluated under a stereomicroscope at 15X magnification by a standardized scale ranging from 0 to 4. One tooth was selected randomly from each group for SEM (Scanning Electron Microscope), and SEM LEO EVO 40 (LEO Ltd., Cambridge UK) photographs of amalgam-tooth hard tissue interfaces were also taken at different magnifications. The results of the microleakage tests were statistically analyzed by both the Kruskal-Wallis Test and the Mann Whitney U Test. Results: In terms of microleakage among groups, the differences that were determined were significant (p<0.05). Microleakage within the control group was determined to be the highest, and statistically important differences were observed between the other groups. Group V (Amalgambond Plus) was determined to have the lowest microleakage scores. Conclusion: In prepared class I cavities, amalgam adhesive systems are effective in preventing occlusal microleakage but do not completely blocked it. How to cite this article: Ünal M, Atakul F.

“…Additionally, it has been and amalgam repairs are equally effective as total replacements in terms of clinical success and can therefore, increase restoration longevity following a minimally invasive treatment concept. 1,15 The bond strength of universal adhesives in composite repair is improved by conditioning with aluminum oxide powder air abrasion and silane, according to research on air abrasion by Kuşdemir et al 20 Giannini et al, 21 in a study concluded that when adhesive systems are used to repair amalgam restorations, roughening an old amalgam surface is an essential step and the simple use of a diamond bur can roughen old amalgam. Dieckmann et al 3 in their study found that air abrasion and bur abrasion seem to be equally effective as mechanical surface pretreatment, which is in accordance with the finding in this study because both mechanical surface pretreatment had acceptable results.…”

Purpose:The purpose of this in vitro study was to evaluate the effect of different surface pretreatment methods on bond strengths of aged composite and aged amalgam rerestored with composite resin. Materials and methods: A total of 72 specimens measuring 5 × 5 × 3 mm were fabricated. A total of 36 composite resin specimens and 36 amalgam specimens were fabricated using customized metallic molds. All the samples were artificially aged by thermocycling (5,000 cycles, 5°-55°C) and then stored in artificial saliva for 1 month. The specimens were divided into six groups (each having 12 specimens) based on different surface treatments (group I-aged composite treated with diamond bur; group II-aged composite treated with diamond bur and silane coupling agent; group III-aged composite treated with air abrasion and silane coupling agent; group IV-aged amalgam treated with diamond bur; group V-aged amalgam treated with diamond bur, metal bond, and silane coupling agent; and group VI-aged amalgam treated with air abrasion metal bond and silane coupling agent). All specimens were then rerestored with composite restoration and again kept for thermocycling. The specimen was tested under universal testing machine for shear bond strength. Statistical analysis was done using analysis of variance (ANOVA) and post hoc analysis. Results: Aged composite treated with air abrasion and silane coupling agent (group III) exhibited the maximum bond strength with a mean of 52.3385 ± 10.656 MPa, followed by aged composite treated with diamond bur and silane coupling agent (group II) with a mean of 50.653 ± 13.182 MPa. The least strength was displayed in aged amalgam treated with diamond bur (group IV) with a mean of 26.3 ± 9.421. One-way ANOVA showed statistically significant difference (p = 0.001) among the groups. Conclusion: Aged composite treated with air abrasion and silane coupling agents increases the bond strength of the repaired composite efficiently. Mechanical surface treatment of aged amalgam along with silane coupling agent and metal bond in cases amalgam repair with composite also improves the bond strength and can be a better alternative in such cases.

“…HEMA is a hydrophilic material which can decrease the surface tension, besides the increasing amount of HEMA result in increasing SBS, 40% of HEMA for nonprecious metal, and 30% for precious metal(1). Also, low viscosity of ABU might be related to better wettability of amalgam, and consequently higher SBS value (32).…”

background: the bond strength of bracket to the tooth substrate is a critical matter. The different surface treatments are introduced to achieve an appropriate bond strength. We aimed to investigate the shear bond strength(SBS) of metal brackets to amalgam surfaces with universal adhesive and compared the results with the enamel group. Material and methods: in this in-vitro study, eighty specimens of amalgam in four groups and sixty specimens of the enamel in three groups were prepared. In amalgam groups, the control group was sandblasted and treated with transbond Xt whilst the other three groups prepared in the following order, group 2 sandblasted and treated with All Bond Universal(ABU), group 3 using diamond bur and ABU, and group 4 using self-etch mode of ABU. In enamel groups, control group was acid-etched and using transbond XT as a primer; in other two groups, the ABU was used as a primer in etched and self-etched mode. The specimens thermocycled and prepared for the SBS test. SEM analysis and ARI index were performed. pvalue≤ was considered significantly. Results: SBS of enamel was significantly higher than amalgam. Within enamel groups, etched with ABU showed the highest SBS. In amalgam group, the highest SBS was related to surface treated with ABU only, and the lowest SBS was related to diamond bur group. Conclusion: The etched surface of enamel showed the appropriate bond strength to bracket, and in the amalgam group, using mechanical preparation can decrease the oxide layer and compromise amalgam SBS.
