About this study

The aims of this randomized control trial are:

To describe a method to chemically etch the bases of stainless steel orthodontic brackets.
To observe the changes in the micro-structure of the brackets with sandblasted bases and acid-etched bases under an electron microscope.
To compare the failure of orthodontic brackets with a chemical etched base versus a sandblasted base bonded with composite using the conventional acid etch technique, over a follow-up of 18 months

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patients about to undergo fixed orthodontic therapy

Exclusion criteria

Patients with cavities, history of fixed orthodontic therapy, recent bleaching

Treatment and study plan

Acid etched brackets

Device

The brackets will be bonded to the teeth with composite on the same patient in a split mouth design and observed for bracket debonding for 18 months

Sandblasted brackets

Device

The brackets will be bonded to the teeth with composite on the same patient in a split mouth design and observed for bracket debonding for 18 months

Primary outcomes

Bond Failure Rate

Time frame: 18 months after placement of brackets on the teeth

To compare the bond failure rates between acid etched and sandblasted brackets. Done by calculating and comparing the percentages of bracket breakages between the acid etched and sandblasted bracket quadrants.
