Abstract :
Background: Orthodontic Treatment Can Be Related to Various Pulp Reactions Such As Hyperemia, Loss of Pulp Life Due to Secondary Dentin Formation, Internal Root Analysis, Bleeding and Pulp Necrosis. The Purpose of this Study is to determine the changes in pulp response to EPT Test in Different times were constant in patients undergoing orthodontic treatment. Materials and Methods: This Prospective Descriptive-Analytical Study on the Maxillary and Mandibular Incisor Teeth of 22 Patients, Before the Start of the Treatment and Bonding of the Brackets, the Response to the EPT Test was Recorded, the Tooth Surface was Divided Into 6 Squares and The Middle Third of the Surface of the Incisors was Chosen for the Reproducibility of the Measurement. At Intervals of 9 Months after the Start of Treatment and 3 Months after Opening the Brackets, The Patients were called to repeat the Electric Pulp Sensitivity Test, and the Response was recorded. The Data were analyzed with Chi-square and Friedman statistical tests Results: There was no significant difference in the response to EPT in incisors teeth 9 months after the start of treatment (P = 0.141) and three months after opening the brackets (P = 0.585). Comparison of the EPT test results between 9 months and 3 months after opening the brackets had a significant difference in all the studied teeth (P < 0.001). Conclusion: Based on the Results of this Study, Most of the Central and Lateral Teeth of the Upper and Lower Jaw Had an Increased Response to the Electrical Test in Both Intervals, Although the Difference in the Recorded Response was not Significant. Also, The Position of the Teeth Does Not Differ in the Recorded Response
