Orthodontic Bond Failure Rate using Light Cure Adhesive in a Tertiary institution in North Central Nigeria.

Abstract

Background: Orthodontic treatment involves many procedures including direct bonding of an orthodontic bracket to the tooth using a variety of techniques, including the acid etch technique. An orthodontic bracket bond failure is said to have occurred when the bracket attachment to the enamel surface of a tooth ceases to be attached by the adhesive bond.

The aims of this study were to determine the failure rate of Orthodontic brackets bonded using light-cure adhesive and to determine the effect of age and sex on bracket failure rate. Methods: One hundred and one patients (101) made up of forty-one males and sixty females respectively (41 M, 60 F), with a mean age of 16.52 ± 8.32 years participated in the study, using an interviewer-administered questionnaire. A total of one thousand five hundred and twenty-six brackets were bonded by a single operator using light cure adhesive. Data was analyzed using frequency, percentage, mean statistics, t-test, correlation, and multiple linear regression analyses. A p-value of 0.05 or less was considered statistically significant. Results: The orthodontic bond bracket failure rate was 10.2%.Age and sex were significant predictors of bracket failure rate ( p-values of 0.001 and 0.013) respectively.

Conclusion: The bracket failure rate was similar to other studies. In this study, age and sex had a significant influence on the bracket failure rates of orthodontic brackets.
