Effects of the Different Orthodontic Fixed Retainers on Enamel Colour Change

Not Applicable

• Conditions: Tooth Color
• Interventions: Other: Bond-a braid; Other: EverStick-Ortho; Other: Ribbond

• Registration Number: NCT04105829
• Lead Sponsor: University of Gaziantep

Brief Summary

The aim of this study is to compare the tooth colour changes caused by retainers made of stainless steel wires and fiber reinforced in long term

Detailed Description

30 patients who were planned to use lower fixed retainer after fixed orthodontic treatment, were included in the study and divided into 3 groups. (n=10) (Group 1: Bond a braid retainer, Group 2: Ribbond retainer, Group 3: EverStick Ortho retainer). Colour measurements will be made with spectrophotometer (Vita easyshade) after debonding (T1), after retainer application (T2), in 1 month, 3 month, 6 month and finally 1 year from 6 lower anterior teeth. The Commission Internationale de I'Echairage L\*a\*b\* system will be used to determine the tooth colour. ∆E values measured at different times will be compared.
