“…24,26,29,30 The ARI assessment is subjective and can be affected with the mode of observation; however, previous studies found the system of value and found that interobserver and intraobserver variability was low. 21,30 Scarring of the enamel after resin removal is welldocumented for the different methods of resin removal 31,32 and may partially explain the increase in bond strength and ARI scores that were observed in this study after the second and third debondings. These increases may also be attributed to the presence of residual adhesive on the surface to which the adhesive used in the second or third bonding can be mechanically or chemically bonded.…”

Objective: To compare rebonding of orthodontic brackets based on the hypothesis that no difference would be found between the adhesive systems with respect to shear bond strength, mode of failure, and clinical failure rates. Materials and Methods: The three adhesive systems included two self-etch primers (Transbond and M-Bond) and a conventional phosphoric acid etch (Rely-a-Bond). The sample size was 20 premolars for each adhesive system. The shear bond strength was tested 24 hours after bracket bonding with the bonding/debonding procedures repeated two times after the first debonding. Bond strength, adhesive remnant index (ARI), and failure sites were evaluated for each debonding. Statistical analysis consisted of a two-way analysis of variance (ANOVA) followed by Scheffè analysis. The clinical portion evaluated 15 patients over a 12-month period. Results: The mean shear bond strengths after the first, second, and third debondings for Relya-Bond were 8.4 Ϯ 1.8, 10.3 Ϯ 2.4, and 14.1 Ϯ 3.3 MPa, respectively; for Transbond 11.1 Ϯ 4.6, 13.6 Ϯ 4.5, and 12.9 Ϯ 4.4 MPa, respectively; and for M-Bond 8.7 Ϯ 2.7, 10.4 Ϯ 2.4, and 12.4 Ϯ 3.4 MPa, respectively. After the three debondings the mean shear bond strength increased significantly from the first to the third debonding for Rely-a-Bond and M-bond (P Յ .001), but did not change for Transbond (P ϭ .199). Conclusions:The original hypothesis is not rejected. The two self-etching primers showing higher or comparable bond strength to the conventional phosphoric etch with less adhesive remnant on the enamel surface after the first debonding. With repeated bonding/debonding, the differences in the bond strength, ARI, and failure site were not significantly different. There was no difference in the clinical performance of the three adhesive systems (P ϭ .667).

“…These sealant materials require three different agents: an enamel conditioner, a primer solution, and an adhesive resin. Although most clinicians accept 37% phosphoric acid as the standard enamel conditioner, some authors argue that acid etching produces an iatrogenic effect that results in enamel surface loss, estimated at between 10 and 30 μm [13][14][15] . Furthermore, the resin tag can penetrate up to 50 μm into the enamel.…”

“…Furthermore, the resin tag can penetrate up to 50 μm into the enamel. Cleanup of the adhesive after bracket removal produces a total enamel loss of between 50 and 55.6 μm [13][14][15][16][17] . To reduce enamel loss and simplify bonding, selfetching primers have been introduced in orthodontics 18) .…”

This in vitro study compared the shear bond strength (SBS) and adhesive remnant index (ARI) of two systems for bonding orthodontic brackets to enamel. The first system involved a self-etching primer (Beauty Ortho Bond, BO) containing surface pre-reacted glass filler. The second involved a primer applied with phosphoric acid etching (Transbond XT, TX). Ninety-six extracted human premolars were divided into eight groups: Group I (TX/direct bonding), Group II (TX/indirect bonding), Group III (BO/direct bonding), and Group IV (BO/indirect bonding). Groups V-VIII were identical to Groups I-IV, respectively, but were also subjected to 1,500 thermal cycles between 5 and 55°C. ARI was scored by binocular microscopy. SBS was analyzed by three-way ANOVA and the Bonferroni test. ARI was analyzed by the chi-squared test. The BO groups showed lower SBS and ARI results than the TX groups. SBS was significantly influenced by the primer material, bonding technique, and thermal cycling.

“…Care to preserve the enamel surface is necessary during orthodontic treatment, to keep the initial surface roughness and smoothness, especially during removal of accessories, when the risk of fracture is higher 8 . Removal of brackets and subsequent cleaning of teeth enamel can be time-consuming for the dental surgeon.…”

Descritores: Resistência ao cisalhamento; braquetes ortodônticos; descolagem dentária; adesividade. AbstractObjective: The Primekote  (TP) polymer was incorporated to the of Orthodontic Bracket mesh base to improve bond strength and make it more efficient. The purpose of this study was to assess the shear bond strength and adhesive remnant index (ARI) of these brackets. Material and method: The test sample consisted of thirty bovine incisors divided into 2 groups: with a group with TP  brackets (n=15), and a control group with Morelli  brackets (n=15) without Primekote  technology. The TransbondTM XT was used as adhesive system in both groups, following the same protocol and manufacturer's instructions. Specimens were stored in distilled water for 24 hours and then submitted to shear bond strength test in a universal testing machine (EMIC DL2000). The assessment of ARI was performed under stereomicroscope by two calibrated examiners. Result: No significant differences (p>0.05) in shear bond strength were found between the two groups according to the independent t-test. The Wilcoxon test was used to assess ARI data and statistical difference was found between Morelli  and TP  Nu-Edge brackets; the last one left less remaining adhesive on tooth surface. Conclusion: TP  brackets had higher adherence to the adhesive system as shown by lower ARI scores, but this does not improve its clinical performance.
