Abstract

Background:  Fixed orthodontic appliances are associated with increased risk of white spot lesions following debonding. The objective of this study was to validate the relationship between the brackets being used on the prevalence of white spot lesions.  Materials and Methods: The sample size comprised of 16 subjects (age 15-35years) divided equally into 2 groups. Immediately after debonding, pumicing for a few seconds and drying with a stream of compressed air for 10-20 seconds the carious state of the vestibular enamel of incisors, canines, premolars and first molars in both jaws were recorded under direct illumination from a dental lamp. A modification of the scoring system proposed by Gorlick et al (1982) was used for assessment of the extension of carious white spots. The number of teeth with carious white spots regardless of localization, opacity and extension, was calculated for each person. Chisquare test was used to determine any statistically significant differences among the groups in distribution of patients with teeth affected by carious white spots. Results: Both the appliances showed prevalence of white spots at the time of debonding with least number of lesions in the lingual appliances. Molars were the most affected teeth with WSLs in both the groups, with more severe lesions among mandibular (MBT) arches. Conclusion: Thus, it was concluded from the present study that WSL incidences in both maxillary and mandibular arches in subjects treated with the lingual STB appliance were distinctly reduced compared with enamel decalcification after conventional labial MBT treatment.
