Finally, each block was bonded on the enamel surface with the corresponding sealant; and light-cured with Ortholux Luminous Curing Light (3 M Unitek) for 20 s. The bonded samples were stored in water at 37 °C for 24 h, previous to the SBS test.

Fifty extracted mandibular premolars were randomly divided into five groups (n=10). Each was treated with the traditional pre-bonding method to enamel as follows: pumiced for 10 seconds, rinsed thoroughly, etched with 35% phosphoric acid gel for 30 seconds, rinsed thoroughly for 20 seconds, air dried, applied Transbond XT light-cure adhesive primer (3M Unitek, CA, USA) for 5 seconds, air dried for 5 seconds. Then, each group of adhesive was applied to the bracket base and the resin was pressed onto the enamel surface. The excess of adhesive was removed with an explorer and light-activated for 40 seconds (3M Unitek Ortholux™ Luminous Curing Light). All bonding procedures were performed according to the manufacturer’s instructions. The shear bond strength was tested on each group using an Instron 5566 Universal Testing Machine (Norwood, MA, USA) at a crosshead speed of 1mm/minute. The SBS was calculated into megapascals (MPa) using the formula MPa = F/A; where F is the maximum load, and A is bracket base area in mm2. The brackets used were mandibular premolar brackets, 0.022-in slot (Orthos, Ormco, Orange, CA, USA). Each tooth was embedded in self-cured acrylic resin with its long axis perpendicular to the horizontal plane.

In strict accordance with the protocol described by Alessandri Bonetti et al.,19 (link) the labial enamel surfaces were cleaned, polished, and etched. A thin uniform coat of primer (Transbond XT; 3M Unitek, Monrovia, CA, USA) was applied by using a microbrush. Adhesive pre-coated metallic brackets (APC II adhesive coating on Victory Series brackets; 3M Unitek) were then placed on the teeth, adjusted to their final positions, and pressed firmly. After removing excess resin from the periphery of the bracket base with a dental probe, the adhesive was cured by using a light-emitting diode light source (Ortholux luminous curing light; 3M Unitek) for 6 s (3 s mesially and 3 s distally), according to the manufacturer's instruction.

The buccal surface of each tooth was cleaned with non-fluoridated pumice using a rubber prophylactic cup for 10 s and then rinsed with sterile water for 10 s.17 After the teeth were etched with 37% phosphoric acid for 15 s, they were rinsed with sterile water for 15 s and then dried for 5 s using an oil-free air syringe. Bonding primer was applied to the etched surface, and the brackets were bonded with composite resin. Excess composite was gently removed with a scaler before curing. Composite resin was light-cured using either VALO® (Ultradent Products Inc.) or an Ortholux luminous curing light (3M Unitek, Monrovia, CA, USA). All brackets were bonded by one clinician. The same curing mode was used for all applications in order to compare the shear bond strengths of the metal and ceramic brackets. Each sample was stored in 100% relative humidity for 24 h prior to the experiment.18 20 Additional details about the materials used in this study are provided in Table 1 .

A total of 150 sealant blocks (25 p/g) 3 × 2 × 1.5 mm was made and filled into a Teflon mould, covered with a micro-slide glass and polymerised 20 s with Ortholux Luminous Curing Light (3 M Unitek, Monrovia, Calif., U.S.A.)

The buccal enamel surface of each premolar was etched with 37% phosphoric acid (Scotch Bond, 3 M ESPE, St. Paul, MN, USA) for 30 s, rinsed with water for 30 s, and then properly dried with oil- and moisture-free air. As prescribed by the manufacturer, experimental primers were applied to the buccal surface of the premolars. A thin, uniform layer of the experimental orthodontic primers was applied to the etched surface. The adhesive was applied to the base of the brackets before insertion. The orthodontic metal brackets (Geousis Mini Roth, ORMCO, CA, USA; lot number: 120114) were then lightly placed on the tooth surface and firmly pressed into their final position. A half-kg customized metallic tool was used to apply standard, uniform pressure to the top of the brackets during the bonding process, resulting in uniform adhesive thickness. An explorer was used to remove the excess adhesive. The entire adhesive resin was polymerized for 12 s in two directions (6 s each) using the Ortholux Luminous Curing Light (3 M Unitek; Monrovia, California, USA; light output: 1600 mW/cm2) [2 (link)]. Subsequently, the bonded premolars were stored in distilled water at 37 °C for 24 h to allow proper polymerization of the bonding process.

The buccal surface of the teeth was etched with 37% phosphoric acid (Master-Dent, Dentonics, USA) for 30 s, rinsed by air and water spray for 30 s, and dried by oil-free air spray until a chalky white appearance was achieved.
After surface treatments, Transbond XT adhesive primer (3M Unitek, Monrovia, USA) was applied to the surface of specimens in Groups 1, 3, 5, and 7, while All-Bond Universal (Bisco, Schaumburg, IL, USA) was applied to the surface of specimens in Groups 2, 4, 6, and 8, followed by gentle air spray for 1–2 s. The maxillary premolar brackets (Ortho Organizers, Inc, Carlsbad, USA) with a mean base surface area of 9.76 mm2 were bonded with Transbond XT (3M Unitek, Monrovia, USA). Excess composite was removed, and light curing was performed by a light-curing unit (Ortholux Luminous Curing Light, 3M Unitek, USA) with a power of 450 mW/cm2 for 20 s from both sides. After bracket bonding, the specimens were immersed in distilled water and incubated at 37°C for 24 h (Pars Azma Co., Tehran, Iran). Samples were thermocycled 1000 times (Delta Tpo2, Nemo, Iran) at 5–55°C with a dwell time of 30 s and a transfer time of 15 s.
Finally, the bracket debonding was done by a universal testing machine (K21,046, Walter + bai, ohningen, Switzerland) at a crosshead speed of 1 mm/min. Shear load was applied to the bracket-tooth interface. SBS was calculated in MPa.

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
