“…These variables may lead to stress on the adhesive and on the brackets, which may affect bond strength. 31 Therefore, thermocycling was used to produce a better simulation of the intraoral conditions. In this study, we used single-tooth trays.…”

Objective: To determine the influence of two adhesion boosters on shear bond strength and on the bond failure location of indirectly bonded brackets. Materials and Methods: Sixty bovine incisors were randomly divided into three groups (n 5 20), and their buccal faces were etched using 37% phosphoric acid. In group 1 (control), brackets were indirectly bonded using only Sondhi adhesive. In groups 2 and 3, the adhesion boosters Enhance Adhesion Booster and Assure Universal Bonding Resin, respectively, were applied before bonding with Sondhi. Maximum bond strength was measured with a universal testing machine, and the location of bond failure was evaluated using the Adhesive Remnant Index (ARI). One-way analysis of variance followed by the Tukey test (P , .05) was used to compare the shear bond strength among groups, and the differences in ARI scores were evaluated using the Kruskal-Wallis test (P , .05). The Pearson correlation coefficient was calculated to determine whether there was any correlation between bond strength and ARI scores. Results: The mean shear bond strength in group 3 was significantly higher (P , .01) than in the other groups. Evaluation of the locations of bond failure revealed differences (P , .05) among the three groups. There was a moderate correlation between bond strength and ARI scores within group 3 (r 5 0.5860, P , .01). Conclusion: In vitro shear bond strength was acceptable in all groups. The use of the Assure adhesion booster significantly increased both the shear bond strength of indirectly bonded brackets and the amount of adhesive that remained on the enamel after bracket debonding.

“…3 Several studies have defined the ideal concentration of orthophosphoric acid and the ideal application time to achieve effective bond strength and minimal enamel loss. 1,[8][9][10][11] However, to obtain better bond strengths and to preserve the integrity of enamel, other methods to prepare enamel surface have been suggested: different acids, [12][13][14] high-power laser irradiation, 7,15 self-etching primers, 7,16,17 and sandblasting with aluminum oxide particles. 5,7,15,16,[18][19][20][21][22] Several studies have investigated the effect of enamel sandblasting with aluminum oxide particles before orthophosphoric acid etching on bracket bond strength.…”

“…In the presented experiment, the Transbond XT was used in both test groups. It has been used in many studies, [18][19][20][21] so the results can be comparable. The bonding material Transbond SEP Plus has also been proven to be one of the best bonds used in orthodontics.…”

Background. Adhesive materials used in orthodontics have contributed to the broadening of treatment options with fixed braces. The adhesive materials physically and chemically bond to the enamel surface and orthodontic bracket base, which, apart from offering advantages, also entails the risk of enamel damage when removing these materials from the tissue surface after the treatment is complete. Objectives. The objective of this study was to assess how the bond strength of adhesive materials affects enamel thickness after removing brackets and whether the type of bonding system affects the amount of adhesive strength of the discussed materials. Material and methods. The tests were carried out on 2 groups of 40 bovine teeth in each group. In the 1 st group, the classical orthophosphoric acid and the Transbond Plus self-etching primer (SEP) were used. In the 2 nd group, the Transbond XT SEP was applied. In both groups, Transbond XT Light Cure Adhesive was used. The same metal orthodontic brackets were attached to the enamel surface. Optical Coherence Tomography (OCT) scans were made before and after removing brackets, which enabled tissue thickness measurements. The bond strength was evaluated using a universal testing machine. Parametric tests were performed on all obtained variables. Student's t-tests for independent samples and analysis of correlation with Pearson's r were carried out. Results. The bond strength between the orthodontic bracket and enamel is statistically significantly different in the 1 st group and the 2 nd group, and is higher in the 2 nd group. Conclusions. There are no significant differences in enamel thickness depending on the bonding system type and there is no correlation between the enamel thickness and the bond strength of orthodontic brackets to the enamel.
