About this study

Official title: Comparison of Shear Bond Strength of Different Commercial Brands of Stainless Steel Orthodontic Brackets: An in Vitro Study

some orthodontic brands are more expensive than others, one of the primary outcomes of this study is to know if is it worth using expensive brands? will it provide better quality treatment, in particular, bond strength? The treatment duration is long therefore it is expensive, either for the orthodontist and/or the patient.

This study will be comparing the bond strength of different commercial brands of stainless steel brackets.

Read the detailed description

There are a plethora of studies in the science of orthodontics discussing different massive advances in the orthodontic adhesion concepts that allowed orthodontists to successfully bond brackets and tubes to teeth. the bond strength between the bracket and tooth should be sufficient to withstand the forces of mastication and the aggressive conditions of the oral environment. a commonly encountered problem is the failure of the bond between the bracket and tooth during treatment.

There are a lot of orthodontic in vitro studies that discussed bond failure and strength. multiple studies have studied the bracket-enamel bond strength with different curing systems and found that there was no significant difference in terms of bond strength. Several other studies discussed the effect of different adhesive systems on the bond strength to the enamel.

There are many studies that debated the shear bond strength of different metal bracket base shapes and sizes concluding that no differences in SBS for the surface area within the range of 6.82-12.35mm2 as well as the shape of the bracket base had no effect on shear bond strength.

The effectiveness or the success of the orthodontic treatment is arbitrated by achieving better aesthetics, better function, and better judgment for the patient too.

Even if there was a plethora of studies comparing the bond strength of different bracket shapes and sizes and also between metal and ceramic brackets, however, none have considered comparing shear bond strength of different bracket brands to enamel, Considering its cost and repeated failure which has its implication on both patient and orthodontist.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Estimation of Shear Bond StrengthOther

    Also called Evaluation of Adhesive Remnant Index

    Measuring shear bond strength between the different bracket brands and the enamel will be estimated by aiming the edge of the blade of the universal testing machine at bracket-enamel interface. The force required to debond each bracket will be registered in Newtons (N), and converted to Megapascals by dividing the force registered in newtons on each bracket base area (mm2).

    After bond failure, the brackets and the enamel surfaces will be examined and assessed for the amount of adhesive remaining on the bracket bases by using digital microscope at 35x magnification. this will identify the site of bond failure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Estimation of Shear Bond Strength

    Measuring shear bond strength between the different bracket brands and the enamel will be estimated by aiming the edge of the blade of the universal testing machine at bracket-enamel interface. The force required to debond each bracket will be registered in Newtons (N), and converted to Megapascals by dividing the force registered in newtons on each bracket base area (mm2).

    Measured: 24 hours

Secondary outcomes (1)
  1. Evaluation of Adhesive Remanent Index

    ARI scale is used to asses site of bond failure After bond failure, the brackets and the enamel surfaces will be examined and assessed for the amount of adhesive remaining on the bracket bases by using digital microscope at 35x magnification.

    Measured: 24 hours
