“…Our findings showed that both adhesive and mixed modes of failure characterized the fractures seen with Vertise Flow, which was consistent with other studies (Juloski et al, ; Veli et al, ). However, in groups used to test the adhesive associated with Premise Flowable composite, the most frequent fracture modes were cohesive and mixed.…”

The aim of the study was to evaluate the adhesion of a self-adhering flowable composite resin to primary tooth enamel and dentin after silicon carbide paper (SiC) and laser pretreatment. Adhesive properties were evaluated as shear bond strength (SBS) and scanning electron microscopic (SEM) characteristics. A total 120 primary canine teeth were randomly divided into two groups to study enamel and dentin. Each group was divided into 6 subgroups (n = 10) according to type of surface preparation (SiC or Er:YAG laser) of enamel or dentin. Three methods were used to build cylinders of restoration on tooth surface: OptiBond All-In-One + Premise Flowable composite, OptiBond All-In-One + Vertise Flow and Vertise flow. After restoration, samples were tested for SBS and failure mode. Twenty eight samples were examined by SEM. The results of the study showed SBS of Vertise Flow was lower than others in enamel and dentin samples pretreated with SiC and in dentin samples pretreated with laser (P < 0.001). Compared to SiC pretreatment, laser pretreatment led to a significantly higher SBS with Vertise Flow on enamel (P < 0.001). Vertise Flow associated with the adhesive led to a higher SBS in enamel and dentin compared to Vertise Flow alone. Adhesive and mixed failure modes were observed more frequently in Vertise Flow groups. SEM images showed that Vertise Flow led to more irregularities on enamel and more open dentinal tubules after laser ablation compared SiC pretreatment.

“…TBLR has been developed specifically for bonding lingual retainers and is used extensively in clinical practices and recent experimental studies, commonly as the control adhesive [16,19,21,23]. TBXT is an orthodontic bonding adhesive resin used mostly for brackets but has been occasionally used for the construction of fixed retainers in the laboratory setting [5,22,23]. The rest of the three products were tested for comparison purposes.…”

“…ACC is a flowable composite, IPS-ED is a nanohybrid and ZNano a nanoparticle restorative composite. Although these materials have no indication for orthodontic bonding, restorative dental resin has been used in the past for the preparation of lingual retainers in a clinical or laboratory setting [2,23]. Recently, some flowable composites, originally created for restorative dentistry, have been used for the construction of fixed retainers [7,9].…”

“…The stipulation to achieve life-long retention after orthodontic treatment makes high adhesive forces a prime goal for an adhesive for fixed retainers, especially given that detachment has been recognized as the main cause for retainer failure [6]. Accordingly, increased shear bond strength [21,23] and wire pull out resistance [3] are required. Moreover, a greater surface area of the lingual retainer composite resin remains exposed to the oral cavity than in cases of bracket adhesives.…”

OBJECTIVE The aim of the present study was to test the mechanical properties of different adhesives used in orthodontics for fixed retainers and to investigate their possible interrelations. MA-TERIALS AND METHODS Specimens of six different adhesive resins were prepared: Transbond XT, Transbond LR and an experimental BPA-free orthodontic adhesive, as well as IPS Empress Direct (IPS-ED), ZNano and Accolade. The mechanical properties tested were Martens hardness (HM), indentation modulus (EIT), the ratio of elastic to total work, commonly known as elastic index ( IT) and Vickers hardness (HV). These properties were determined using instrumented indentation testing according to ISO 14577-2002. The results of the aforementioned properties were statistically compared with one-way ANOVA-test and Student-Newman-Keuls multiple comparison test at a=0.05, while possible correlations among the properties tested were analyzed by Pearson correlation. RESULTS Significant differences were identified among all the materials tested for HM, with Transbond LR presenting the highest value. This resin presented the highest EIT too. Significant EIT differences were identified among the materials and only ZNano and IPS-ED showed no significant differences for this property. Transbond LR and ZNano showed higher HV values. ZNano demonstrated the highest elastic index. Pearson analysis showed a strong positive correlation between HM and EIT (0.970), HM and HV (0.837), and EIT and HV (0.695), while a weak negative correlation was found between EIT and elastic index (-0.505). CONCLUSIONS The materials tested demonstrated significant differences in their mechanical properties, and thus differences in their clinical performance are anticipated.

Materials and methods: Specimens of six different adhesive resins were prepared: Transbond XT, Transbond LR and an experimental BPA-free orthodontic adhesive, as well as IPS Empress Direct (IPS-ED), ZNano and Accolade. The mechanical properties tested were Martens hardness (HM), indentation modulus (E IT ), the ratio of elastic to total work, commonly known as elastic index (η IT ) and Vickers hardness (HV). These properties were determined using instrumented indentation testing according to ISO 14577-2002.

“…Not only when measured immediately after application [28], but especially after aging [29,30], self-adhesive composites present significantly lower bond strengths than conventional composites that were applied with a bonding system in the etch-andrinse or self-etch technique. Chemical bonding of GPDM to the calcium present in hydroxyapatite has been positively demonstrated [31]. Unlike etch-and-rinse adhesives, self-adhesive composites are applied directly on the smear layer of dentin surface; etching and subsequent penetration of monomers into the demineralized dentin are carried out as a single step, which is achieved by including polymerizable acidic monomers into the formula [32].…”

Background and Aim: Improving the bond strength at the resin-dentin interface is an important challenge in adhesive dentistry. This study examined the effect of low-power, non-thermal atmospheric pressure plasma (NT-APP) treatments on the adhesion of a self-adhesive resin composite to dentin. Materials and Methods: In this experimental in-vitro study, buccal enamel of extracted bovine incisors was removed using a high-speed diamond bur. The specimens were randomly divided into two groups according to the plasma treatment and thermocycling. The non-thermal atmospheric argon plasma brush was used in this study. One subgroup was subjected to the microshear bond strength (µSBS) test after 24 hours, whereas the other subgroup was subjected to artificial aging with thermocycling for 5000 cycles before being tested. Each specimen was attached to a testing jig and loaded at a crosshead speed of 1.0 mm/minute in a universal testing machine until failure occurred. Data were analyzed using two-factor repeated measures analysis of variance (ANOVA). Results: The results of μSBS testing showed that with plasma treatment, the average μSBS increased to 34.20±12.12 MPa compared to 19.47±7.4 MPa in the controls (P=0.002). After 5000 cycles of thermocycling, the adhesive-dentin bonding strengths of the plasma-treated specimens slightly decreased from 34.20±12.12 MPa to 33.64±5.6 MPa (P=0.886), while the strengths of the untreated specimens reduced from 19.47±7.4 MPa to 19.10±5.1 MPa (P=0.461). Plasma treatment improved the µSBS compared to the control group. After thermocycling, the µSBS did not decrease in the plasma and control (non-plasma) groups. Conclusion: Plasma treatment using NT-APP improves the adhesion of self-adhesive flowable resin composites to dentin.
