“…Enamel was examined at ×10 magnification with the use of a microscope (Stereomicroscope SR, Zeiss, Oberkochen, Germany) in order to determine the amount of adhesive remaining on the enamel of each tooth after the detachment of the splints [27]. This parameter was determined according to the ARI scale ranging from 0 to 3 (0: no adhesive; 1: less than 50%; 2: more than 50%; and 3: 100% adhesive) in order to define the bond failure site [28,29].…”

The aim of this laboratory and clinical study is to determine the reliability of the flowable nanocomposite Filtek Supreme XTE (FL) for the adhesion of orthodontic retainers, compared to highly filled orthodontic resin Transbond XT (XT). Portions of a round section multistranded wire (Ortosmail Krugg) were bonded to 40 bovine incisors with Scotchbond Universal in total-etch modality. For group one (XT, 20 samples), the orthodontic resin was used, whereas in group two (FL, 20 samples), the flowable one. Specimens were placed into a universal testing machine which applied a shear force on retainers with a crosshead speed of one/minute. Shear bond strength (SBS) and adhesive remnant index (ARI) scores were calculated. In the clinical trial, 100 patients requiring a canine-to-canine palatal and lingual retainer were randomly divided into two groups, according to the resin used for bonding procedure: the orthodontic in group one (XT, 50 participants) and the flowable in group two (FL, 50 participants). Monthly visits were carried out over a 24-month follow up to assess any detachment occurring on teeth of both arches. All data were submitted to statistical analysis. In vitro, FL reported a significant lower mean SBS, whereas no significant differences in ARI were reported between the two groups which both showed a major frequency of scores "1" and "2". At the end of the 24-month follow up, FL reported significantly higher failure rates in both arches besides a significantly lower survival rate starting from the sixth month after retainers bonding. According to the results assessed in vitro and clinically, XT would be preferable to FL when performing retainers bonding procedure.

“…The pH values of the adhesives tested showed a relation with the protective effect presented by the adhesives. G-aenial bond had a more pronounced protective effect and has the lowest pH (1.5) of all the products tested, 35 while the Futurabond U, with a pH = 2.3, presented an intermediate result and the Single Bond Universal, less effective, has pH = 3.0.…”

Aim: This study evaluated the efficacy of self-etching adhesive systems associated or not associated with the neodymiumdoped yttrium aluminum garnet (Nd:YAG) laser on the protection against enamel erosive/abrasive wear. Materials and methods:Bovine enamel specimens were demineralized with 0.3% citric acid (5 minutes). The samples were randomly assigned to eight groups (n = 20): SB -Single Bond Universal (3M/ESPE); SB+L -Single Bond Universal + laser (80 mJ/10 Hz); FB -Futurabond U (Voco); FB+L -Futurabond U + laser; GEN -G-aenial bond (GC); GEN+L -G-aenial bond + laser; L -laser irradiation; and C -no treatment.The laser was applied before light curing. The samples were subjected to erosive/abrasive challenges (0.3% citric acid -2 minutes and tooth brushing four times daily for 5 days). Enamel surface loss was recovered profilometrically by comparison of baseline and final profiles. The adhesive layer thickness, retention percentage of the protective layer, and microhardness of cured adhesive were measured. Data were analyzed using one-way analysis of variance and Tukey's test (5%).Results: There were significant differences for all parameters Conclusion:The application of Futurabond U and G-aenial bond on enamel surface, as well as the Nd:YAG laser irradiation alone, was able to reduce the enamel wear. The use of laser after the adhesive systems did not improve their efficacy.Clinical significance: Erosive/abrasive wear is a prevalent condition in clinical practice affecting many patients. The association of adhesive systems and Nd:YAG laser is of considerable clinical interest because it assesses new treatments to reduce the erosive/abrasive wear that would help dentists in clinical treatment decisions to reduce enamel wear and achieve a successful treatment.

“…This finding agrees with the findings of many previous studies showing that applying acid etch in conjunction with SE adhesive systems, mainly in the enamel, is important. 30,31,[43][44][45][46] The bond strength relies mainly on the adhesive's capability to demineralize the smear layer and the underlying tooth structure. 47 Both the TNB-TE and SB-TE adhesives showed high bond strength values to unbleached and bleached enamel, likely owing to properly etched enamel surfaces and to the many micro-retentions that are achieved with phosphoric acid etching.…”

Aim:This study aimed to examine the effect of postoperative home bleaching using 20% carbamide peroxide on the shear bond strengths of different adhesives to enamel and to verify the failure mode for each test specimen. Materials and methods:One hundred sound human molars were used in this study. Bonding procedures were performed on the flattened buccal enamel surfaces according to the manufacturer's instructions. OptiBond Solo Plus adhesive (Kerr), Single Bond Universal adhesive (3M ESPE) applied with both the total-etch and self-etch techniques, and Tetric N-Bond Universal adhesive (Ivoclar Vivadent) applied with both the total-etch and self-etch techniques were used, followed by resin composite post fabrication (Filtek Z350 XT; 3M ESPE). All specimens were thermo-cycled for 5000 cycles and then divided into the control (non-bleach) and postoperative bleaching groups (20% carbamide peroxide). The shear bond strength values were measured and compared between the two groups. Data were analyzed using one-way analysis of variance with Tukey's test (p ≤ 0.05). The failure modes of debonded specimens were evaluated using a digital microscope (50×). The bonding interfaces of the resin composite posts to different enamel conditions (control and postoperative bleaching) were observed by a scanning electron microscope (SEM) before the shear bond test. Results:The shear bond strength values of all tested adhesives were lower in the postoperative bleaching group than they were in the control (non-bleach) group, particularly the bond strength values of self-etch adhesives. Conclusion:The stability of bonded resin composite restorations to enamel, using different dental adhesives, could be compromised after the bleaching procedure at varying sensitivity levels.Clinical significance: Replacement of bonded resin composite restorations to enamel might be considered after bleaching procedures, especially if these restorations were previously bonded with self-etch adhesives.
