A comparison of white spot lesion formation between a self-ligating bracket and a conventional preadjusted straight wire bracket.
OBJECTIVE
Demineralization following removal of orthodontic appliances is a common problem. Presence of archwires, especially those with loops and different types of ligatures, complicate cleaning around bands and brackets during orthodontic treatment. These factors led clinicians to develop self-ligating brackets. The purpose of this study was to compare the incidence of white spot lesion formation with the use of a self-ligating bracket with conventional preadjusted straight wire brackets.


METHODS
Twenty patients were randomly divided into 2 groups. In the first group (aged 13.4 ± 2.5 years), the teeth were bonded with In-ovation brackets; the second group's (aged 14 ± 3.34 years) teeth were bonded with conventional preadjusted straight wire brackets. The patients were followed throughout treatment, and the number of white spot lesions was noted at debonding.


RESULTS
The results revealed no statistically significant differences in white spot lesion development between conventional straight wire and self-ligating brackets.


CONCLUSIONS
No differences in terms of white spot lesion formation were found between conventional straight wire and self-ligating brackets, and white spot lesion formation does depend largely on patients' oral hygiene status, not the type of bracket or ligation used.
