In vivo evaluation of tooth color alterations during orthodontic retention: A split-mouth cohort study.

OBJECTIVES: To assess in vivo color alterations of teeth following removal of fixed orthodontic appliances during retention.

SETTING AND SAMPLE POPULATION: The Department of Orthodontics at XXXXXX University of XXXXX. Forty eight patients after orthodontic treatment.

MATERIAL AND METHODS: Debonding and cleaning procedures after orthodontic treatment were performed using two different carbide burs attached to a low or high-speed handpiece, respectively, in a non-blinded cohort study with split-mouth design. Spectrophotometric color data of teeth was recorded; (a) after debonding, (b) three months later, prior to and following finishing with Soflex discs, and; (c) after one year. The CIE Lab color parameters were measured for each tooth and the corresponding ΔΕ differences were calculated. The effect on color was assessed with 3-Way Mixed ANOVA and Bonferroni's comparisons test (a<0.05).

RESULTS: Orthodontic debonding and cleaning procedures have statistically significant effects on the CIE color parameters of treated teeth, since the L* values decreased 0.6 units (p<0.001), a* values were stable (0.0 units) and b* values increased 1.4 units (p<0.001), during the first retention year. Finishing temporarily decreased the enamel color differences. Total ΔΕ differences for all types of teeth measured ranged from 1.4 to 2.1 units. The greatest changes were exhibited during the first three months in teeth on which high-speed rotary instruments were used (1.6 units).

CONCLUSION: The clinical relevance of this study notes that the color of natural teeth following removal of fixed orthodontic appliances changes in long-term. This article is protected by copyright. All rights reserved.
