“…It has been the subject of many studies examining its adhesive strength [ 9 , 12 , 15 – 17 ]. In the present study, a mean value was measured for the Transbond XT primer that was comparable to that reported in other studies for the bracket-adhesive bond [ 18 , 19 ]. From the authors' point of view, Transbond XT primer with a conventional acid etching technique can still be regarded as the gold standard for bonding brackets on enamel, except in special clinical situations, as mentioned below.…”

Objective. The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of two self-etching no-mix adhesives (iBond™ and Scotchbond™) on different prosthetic surfaces and enamel, in comparison with the commonly used total etch system Transbond XT™. Materials and Methods. A total of 270 surfaces (1 enamel and 8 restorative surfaces, n = 30) were randomly divided into three adhesive groups. In group 1 (control) brackets were bonded with Transbond XT primer. In the experimental groups iBond adhesive (group 2) and Scotchbond Universal adhesive (group 3) were used. The SBS was measured using a Zwicki 1120™ testing machine. The ARI and SBS were compared statistically using the Kruskal–Wallis test (P ≤ 0.05). Results. Significant differences in SBS and ARI were found between the control group and experimental groups. Conclusions. Transbond XT showed the highest SBS on human enamel. Scotchbond Universal on average provides the best bonding on all other types of surface (metal, composite, and porcelain), with no need for additional primers. It might therefore be helpful for simplifying bonding in orthodontic procedures on restorative materials in patients. If metal brackets have to be bonded to a metal surface, the use of a dual-curing resin is recommended.

Background:There is necessary of dry operating field for bonding of orthodontic brackets. The presence of moisture can alter the bond strength. Hence, the aim of the present study was to evaluate the shear bond strength of orthodontic brackets with different adhesives.Materials and Methods:In this in vitro study, a total of 100 orthodontically extracted premolars with sound crown structure were divided into 4 equal groups of different primers. Bonding on the buccal surface of all teeth was done after acid etching with upper premolar brackets using different primers followed by light curing. Shear bond strength was evaluated with or without salivary contamination with both adhesives. A shear force for deboning the bracket was done with universal testing machine. The debonded specimens were examined at ×10 magnification to check site of bond failure and remaining adhesive on tooth using adhesive remnant index (ARI). The obtained data were statistically evaluated using SPSS 20 for Windows (SPSS Inc., Chicago, IL, USA) using ANOVA, Kolmogorov–Smirnov, and Levene's test at the statistical significance of P < 0.05.Results:Transbond Plus showed higher shear bond strength of 8.92 MPa under dry and 5.65 MPa with saliva contamination over Transbond XT of 7.24 MPa under dry and 2.43 MPa with saliva contamination, respectively. Higher ARI score was found without contamination in both adhesives.Conclusion:Transbond Plus hydrophilic resin had good shear bond strength under both dry and contamination condition compared to hydrophobic Transbond XT resin material.

“…Existen en el mercado diferentes sistemas de adhesión para la fijación de brackets en ortodoncia, entre los cuales se encuentran los sistemas con primer-adhesivo hidrofílicos (mip) y sistemas de resina hidrófila que se han introducido recientemente en la práctica odontológica, los cuales pretenden proporcionar una mejor adhesión al esmalte (Anand et al, 2014). El mip más comúnmente utilizado es Transbond mip (3M Unitek, Monorovia, California, EUA) Transbond mip permite la adhesión en un entorno húmedo sin comprometer su fuerza de adhesión.…”

El objetivo de este estudio fue evaluar el efecto antibacteriano y la citotoxicidad de un adhesivo de uso ortodóncico con nanopartículas de plata (Ag np’s). Se determinó la actividad antimicrobiana mediante una prueba de difusión en disco para Staphylococcus aureus, Escherichia coli, y Enterococcus faecalis a diferentes concentraciones de nanopartículas de plata en un adhesivo ortodóncico. También se evaluó la citotoxicidad de dicho adhesivo al ser incorporadas Ag np’s, mediante el método de mtt. Los resultados mostraron que las bacterias en estudio, S. aureus, E. coli y E. faecalis fueron susceptibles tanto a las Ag np’s como al adhesivo mip ortodóncico adicionado con Ag np’s a concentraciones de 10, 5 y 3 v/v%. El efecto antibacteriano de las nanopartículas de plata es dosis dependiente. La citotoxicidad del adhesivo mip ortodóncico en sí mismo exhibe una citotoxidad ligera a moderada, así como al incorporarle las Ag np’s a las concentraciones antes mencionadas. Las nanopartículas incorporadas en el adhesivo de uso ortodóncico muestran efecto antibacterial así como mantienen una citotoxicidad ligera.
