The use of orthodontic treatments in patients with temporary prostheses has been increasing, the purpose of this in vitro research is to measure the adhesive bond strength between orthodontic resin and acrylic surfaces by applying different procedures. Objective. To compare the adhesive bonding strength between orthodontic resin and acrylic surfaces under different application protocols. Methodology. Transversal, experimental, prospective study. In vitro with acrylic provisions, was carried out in the laboratory of the Faculty of Dentistry of the Universidad Veracruzana region of Veracruz. In the period of February-June of the year 2019. The sample was conformed by two control groups of specimens and four experimental ones, each group conformed by 20 specimens, in total 120 provisional ones were made in acrylic Nic Tone of quick self-cure. The tests performed by the ULTRATESTER machine were expressed in MPa. Later, the data obtained were processed in Excel tables (version) for statistical processing in SPSS version 24. Contribution. When comparing the pre-cutting protocol of acrylic surfaces with fine diamond bur and the protocol without pre-cutting, no statistically significant differences were found, therefore, this step could be omitted in clinical practice.

ABSTRACT Introduction Trichloroacetic acid (TCA) is a soft tissue cauterizing agent applied to gingival margins prior to cervical tooth-colored restorations. The present in vitro study evaluated the effects of two different concentrations of TCA hydrogel as a hemostatic/preconditioning agent on the shear bond strength (SBS) of a self-etch adhesive to tooth structures. Materials and methods Thirty-six flat enamel and 36 flat dentin surfaces were prepared using human molars; each group was subdivided into three subgroups (n = 12). The groups were made ready as follows: In groups 1 (E1 and D1), the enamel (E) and dentin (D) surfaces were designated as control groups and remained intact. In groups 2 (E2 and D2), 35% TCA gel was applied to enamel and dentin surfaces for 30 seconds. In groups 3 (E3 and D3), 50% TCA gel was applied to enamel and dentin surfaces for 30 seconds. Clearfil SE Bond and Z100 composite resin were applied to the surfaces according to manufacturers¡¦ instructions. After 24 hours of incubation and thermocycling, the composite cylinders underwent an SBS test in a DARTEC test machine. Data were analyzed using the ANOVA and Scheffé's test (α = 0.05). Results The mean SBS ± SD in the study groups were 34.73 ± 5.66, 35.32 ± 7.3, 23.75 ± 9.67, 20.94 ± 9.84, 19.32 ± 6.20, 23.50 ± 6.63 MPa in the E1, E2, E3, D1, D2 and D3 groups, respectively. ANOVA revealed significant differences between the SBS values of enamel groups (p = 0.001). There were no significant differences between the dentin groups (p = 0.425). Conclusion Application of 35 and 50% concentrations of TCA to dentin had no detrimental effect on the bond produced by two-step self-etch adhesive under study; however, application of only 35% TCA to enamel did not result in a detrimental effect on the same adhesive.

Adhesive Bond Strength

A primary aim of a manufacturing company is a simplicity and a speed of a production process. This assumption makes prospects in an area of sheet bonding by quik-setting adhesives (cyanoacrylates). Owing to temperature fluctuations in various climatic environments significant changes of the temperature occur. For successful application of particular products it is necessary to investigate a temperature dependence of already hardened adhesives. The paper deals with a research of the environment temperature influence on the strength change of the quick-setting adhesives. The experiment results confirmed a fundamental negative influence of the environment temperature on the strength of the adhesive bonds. A type of the failure area has not change owing to the environment temperature. The aim of the research is to set the influence of the environment temperature on the adhesive bond strength created with different cyanoacrylate adhesives.
