“…It is worth emphasizing that significantly higher values of SBS for ceramic brackets in comparison to those for metal ones in both etching protocols were observed. However, the literature's findings are ambiguous regarding this issue [6,[26][27][28][29][30][31][32][33]. The majority of studies have confirmed the advantage of ceramic brackets over metal ones in terms of the SBS value [6,[26][27][28][29][30] (Table 8).…”

“…According to the literature, specimens should be cycled a minimum of 5000 times with a 60 s dwell time [32,33]; therefore, this protocol was used in the present study. However, most researchers apply their own regimen of thermocycling [26][27][28][29][30], because the values included in ISO TR 11450 (500 cycles, 5 and 55 • C) are considered to be insufficient to achieve the proper aging effect [32,33].…”

“…Metal and ceramic brackets from AO (American Orthodontics, Sheboygan, USA), with bracket base areas of 11.3 mm 2 and 15.1 mm 2 , respectively, were also investigated [30,31]. Similarly to the present study, the ER protocol and Transbond XT were used.…”

“…Similarly to the present study, the ER protocol and Transbond XT were used. One of the above-mentioned studies revealed no statistical difference in the SBS between ceramic (14.62 MPa) and metal brackets (13.71 MPa) [30]. However, the other one proved that metal brackets exhibited a significantly higher SBS (24.92 MPa) in comparison to that of ceramic ones (10.74 MPa) [31].…”

Successful orthodontic therapy, apart from a proper treatment plan, depends on optimal bracket–enamel adhesion. Among numerous factors affecting adhesion, the type of bracket and preparation of the tooth’s surface are crucial. The aim of this study was to compare the shear bond strength (SBS) of metal and ceramic brackets to the enamel’s surface using direct bonding. Forty extracted human premolars were divided into four groups according to the etching method (etch-and-rinse and self-etch) and bracket type. The SBS and adhesive remnant index (ARI) were determined. The ceramic brackets achieved the highest SBS values both in the self-etch (SE) and etch-and-rinse (ER) protocols. Higher SBS values for ceramic and metallic brackets were found in the ER protocol. In all tested groups, the achieved SBS value was satisfactory to withstand orthodontic and occlusal forces. There was no significant difference in the ARI score between study groups (p = 0.71). The fracture occurred between the bracket base and adhesive material in both types of brackets, which decreased the risk of enamel damage during debonding.

Literature reports indicate that during bracket removal there can be enamel damage. We compare the shear bond strength (SBS) and tooth enamel loss of four adhesive systems and identify the Ca/P ratio. Then a total of 20 premolars were divided into four groups of five each. After prophylaxis, photographs were taken at 35× with a scanning electron microscope (SEM) and analyzed with X‐ray spectroscopy (EDS) at 250×. Brackets were bonded with Transbond™ MIP(G1), Transbond™ PLUS SEP(G2), Enlight(G3) and Stylus®(G4) adhesives, 24 h after were debonded with a Instron universal testing machine at 1 mm/min. All the brackets were photographed with the SEM. The amount of lost enamel was measured with AutoCad. All the results were measured with a significance level p < .05. The SBS general average at debonding was 7.94 ± 2.26 MPa, meanwhile the SBS for G1, G2, G3 and G4 was 9.38 ± 1.46, 6.28 ± 0.69, 9.08 ± 2.45 and 7.04 ± 2.64 MPa respectively. 90% of the samples had no enamel loss, 10% had enamel loss. Only two samples in G1 presented an enamel loss area of 0.34mm2 and 0.80mm2 respectively. From EDS analysis, the Ca/P ratio was 1.6 ± 0.05, 1.61 ± 0.03, 1.64 ± 0.83 and 1.59 ± 0.07 for G1, G2, G3 and G4 respectively; no statistically significant differences were found. We conclude that no association was found between the Ca/P ratio and enamel damage when brackets are removed. Highlights Where enamel is lost, we observe fractures, steps, horizontal and vertical enamel loss. There is a loss of tooth enamel from 0.34 to 0.80 mm2 with Transbond PLUS SEP. Structural loss of enamel is almost inevitable during the separation of the bracket.
