“…Other studies using this same kind of material found shearing bond strength with values ranging from 7.5 to 10.57 MPa. 7,18 All results found in this study, including group IV, are near these values (Fig 7). The results indicate that the self-etching system could be used maintaining its characteristic of optimal shearing strength until 9 days after its activation.…”

“…10 Some studies show no statistical significant differences between conventional and selfetching systems on shearing bond strength of metallic brackets. 7,18 Some authors defend the use of bovine teeth instead of human teeth in dental researches. The use of bovine teeth became welldocumented and preferred due to its enamel composition (similar to human's enamel) and its easy acquisition.…”

Objective: To evaluate the shear bond strength of metallic brackets using the self-etching system after its activation and storage for 2, 5 and 9 day periods. Methods: A total of 64 bovine teeth were divided in four groups and prepared to receive the brackets. Initially (T1), 7 self-etching primer blisters were activated and used to bond the brackets of group I. The blisters were stored at a constant temperature of 4ºC for 2 (T2), 5 (T3) and 9 (T4) days and used to bond the brackets of groups II, III and IV, respectively. Results: No statistic difference was found in shear bond strength comparing groups I, II and III. However, a significant difference was found in group IV. Conclusion: The shear bond strength seems not to be affected by activation and storage of the self-etching primer at a mean temperature of 4°C for a 5 day period. More studies are necessary to evaluate other characteristics of the material after its activation and storage for long periods of time. AbstractKeywords: Shear bond strength. Self-etching system.

“…Mean resistance to traction was 6.25 ± 1.61 MPa, practically the same optimal values recommended in the literature 3,4 (6 MPa).Their next in vitro study of bonding to extracted human premolars compared SEP resistance to traction with that of a conventional system using Victory (3M Unitek, Monrovia, CA) metal brackets and the adhesive pre-coated (APC) system. 5 Mean values were 8.1 ± 2.7 MPa in the SEP group, and 10.3 ± 3.2 MPa for the conventional system, similar to those found by Grubisa et al 6 in another comparative study: 7.7 ± 4.2 MPa for SEP and 9.8 ± 4.2 MPa for the conventional system. These findings suggested that the clinical applicability of SEP should be confirmed in clinical trials.…”

Objective: This study compared the clinical performance of orthodontic brackets bonded with Transbond adhesive paste after two priming systems: a two-stage conventional system (acid etching + Transbond XT adhesive primer) and a singlestage self-etching primer (SEP) (Transbond Plus). Methods: The sample comprised 480 metal brackets bonded to the teeth of 24 consecutive patients treated for 36 to 48 months. A split-mouth design was used for bonding, and both systems were used in each patient. Bracket failure rates for each system were analyzed; and failure causes as reported by the patients and the quadrant of teeth for which brackets failed were recorded. Results: The conventional system group had a failure rate of 5.41%, whereas the rate for SEP was 4.58%. In this group, there were 5 failures (38.4%) in the right maxillary quadrant, 2 (15.4%) in the left maxillary quadrant, 4 (30.8%) in the right mandibular quadrant, and 2 (15.4%) in the left mandibular quadrant. In the SEP group, there were 4 (36.4%) failures in the right maxillary quadrant, 1 (9%) in the left maxillary quadrant, 3 (27.3%) in the right mandibular quadrant, and 3 (27.3%) in the left mandibular quadrant. Results of descriptive statistical analysis and odds ratio did not show any significant differences between rates (p = 0.67). Conclusion: The clinical efficiency of SEP was similar to that of the conventional system. » The author reports no commercial, proprietary or financial interest in the products or companies described in this article.original article Objetivo: o objetivo do presente estudo foi comparar o desempenho clínico da colagem de braquetes ortodônticos com resina Transbond (3M Unitek) associada a dois sistemas adesivos: convencional em duas etapas (ataque ácido + Transbond XT adhesive Primer) e Self-Etching Primer (SEP), em etapa única (Transbond Plus). Métodos: a amostra foi constituída de 480 braquetes metálicos (Victory, 3M Unitek), colados em 24 pacientes, que foram tratados durante um período de 36 a 48 meses. A colagem foi feita por meio do sistema split-mouth, utilizando os dois sistemas de colagem em cada paciente. Foi analisada a taxa de queda dos braquetes para cada sistema de colagem, descrita a causa da queda conforme relato do paciente e a posição dos dentes nas arcadas. Resultados: o sistema adesivo convencional apresentou taxa de queda de 5,41%, enquanto a do SEP foi de 4,58%. O sistema convencional apresentou 5 quedas (38,4%) no quadrante superior direito, 2 (15,4%) no quadrante superior esquerdo, 4 (30,8%) no quadrante inferior direito e 2 (15,4%) no quadrante inferior esquerdo. O SEP apresentou 4 quedas (36,4%) no quadrante superior direito, 1 (9%) no quadrante superior esquerdo, 3 (27,3%) no quadrante inferior direito e 3 (27,3%) no quadrante inferior esquerdo. Por meio da análise estatística descritiva e do teste Odds Ratio, constatou-se que não houve diferença significativa entre essas taxas (p = 0,67). Conclusão: com base nesses resultados, pode-se concluir que o sistema adesivo SEP apresentou eficácia clínica s...

“…Otros autores han utilizado temperaturas similares, [25][26][27] sin embargo, han realizado ciclos más cortos y tiempos de inmersión diferentes lo cual limitaría la interpretación del comportamiento en la práctica clí-nica. Es por eso que para futuros estudios sería interesante determinar la influencia del tiempo de tratamiento sobre la fuerza de adhesión a largo plazo mediante el desarrollo de un proyecto de investigación In vivo que compare diferentes sistemas adhesivos.…”
