ABSTRACT
PURPOSE:
The aim of this study was to compare if there was any difference in the enamel discoloration after staining when three orthodontic adhesives and 4 enamel clean-up methods were tested.METHODS:
Three types of orthodontic adhesives were used chemically cured resin, light-cured resin and resin-modified glass-ionomer cement. A total of 120 human extracted premolars were included. Ten teeth of each orthodontic adhesive were randomly cleaned-up with 1 of 4 different procedures and stained in coffee for 7 days carbide bur (TC), carbide bur and Sof-Lex polishers (TCï¼SL), carbide bur and One Gloss polishers (TCï¼OG), carbide bur and PoGo polishers (TCï¼PG). Colour measurements were made with Crystaleye dental spectrophotometer at baseline and after storage in a coffee solution for 1 week. Two way ANOVA and Bonferroni test were used for statistical analysis with SPSS 13.0 software package.RESULTS:
The colour change values of adhesive materials in the TC group were the greatest. The lowest ΔE* values were obtained from the TCï¼SL group. However, there was no significant difference between the TCï¼SL and TCï¼PG group (P>0.05). The resin-modified glass-ionomer cement group showed the lowest colour differences and chemically cured resin group showed the highest ΔE* values among all orthodontic adhesives (P<0.05).CONCLUSIONS:
The colour change of enamel surface is affected by the type of adhesive materials and clean-up procedures.
