The aim of this study is to determine the changes in taste perception that may occur before and after the initiation of treatment in patients undergoing fixed orthodontic treatment. A total of 128 patients from Biruni University Faculty of Dentistry, Orthodontics Clinic, were randomly selected to either a fixed orthodontic treatment group (n=64) or a control group (n=64), Taste sensation was assessed using nine solutions representing different taste modalities (sweet, salty, sour and bitter), with evaluations conducted via a Visual Analog Scale (VAS) before treatment and six weeks post-treatment. Statistical analyses were performed using the Mann-Whitney U test, Wilcoxon Signed-Rank test and Pearson Chi-Square test. The study found statistically significant differences in sweet taste perception between the first and second sessions in the low-dose experimental group and in bitter taste perception in the high-dose experimental group (p\<0.05). However, no statistically significant differences were observed between the experimental and control groups across all taste types and time points (p\>0.05). While orthodontic treatment resulted in some changes in sweet and bitter taste perception, no overall significant differences were found between the experimental and control groups. Increased salivary flow rate during treatment and good oral hygiene may help minimize potential effects on taste perception.
