Abstract

Aim

The aim of the study was to evaluate and compare the shear bond strength of the brackets bonded with two different orthodontic light cure adhesives.

Material and Methods

Ten extracted human premolars were divided into 2 groups. Premolar brackets were bonded to the tooth specimens in each group with their respective adhesive according to the manufacturer's instructions. Group1-bonded with Transbond XT [3M UNITEK] and Group2-tooth specimen bonded with Grengloo[Ormco] and then examined for shear bond strength. The teeth were placed in INSTRON universal testing machine at crosshead speed of 0.5 mm/minute, and the shear force to remove the brackets was recorded.

Results

The independent test revealed that there was no significant difference between the shear bond strength of the two groups. The mean shear bond strengths of two adhesive systems showed no significant differences.

Conclusions

The mean shear bond strengths of two adhesive systems showed no significant differences
