Clinical Trial 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

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.
