Methods: Forty human premolar teeth were utilized and randomly divided into four groups based on the type of brackets and finishing technique: (1) Gemini((R)) brackets were used for orthodontic bonding. After debanding, adhesive remnants were cleaned using a 12-blade tungsten carbide bur. (2) Gemini((R)) suspenders were used for orthodontic bonding. After debanding the brackets, adhesive remnants were cleaned using12-blade APC(TM) Flash-Free brackets were used for orthodontic bonding. After debanding, adhesive remnants were cleaned a 12-blade tungsten carbide bur and polished with Sof-Lex disks. (4) APC(TM) Flash-Free brackets were used for orthodontic bonding. After debanding, the adhesive remnants were cleaned using a 12-blade tungsten carbide bur. A Vita Easyshade spectrophotometer was used to measure the color change values of the 40 teeth. Results: The color change of the enamel surface in the Flash Free bracket group was significantly less than that in the conventional groups (p=0.003 p < 0.05). The mean.E values obtained from the Sof-Lex groups were lower than those obtained from the groups without Sof-Lex, but these results were not statistically significant (p=0.280 p > 0.05). Conclusion: It is recommended to use Flash-Free brackets and polish with Sof-Lex disk following the clean-up procedures to minimize the possibility of discoloration of the teeth during orthodontic treatment.eninfo:eu-repo/semantics/openAccessTeeth discolorationadhesive precoated bracketsspectrophotometerArticle36424825310.4274/TurkJOrthod.2023.2022.154381640122-s2.0-85181513761Q21242639WOS:001167607600005Q4
