TOOTH DİSCOLORATİON AFTER ROOT CANAL TREATMENT WİTH AH PLUS AND BİOROOT RCS

he purpose of this clinical study is to compare tooth color changes after root canal treatment using two different root canal sealers, AH Plus and BioRoot RCS, in upper front teeth. The main questions this study aims to answer are: Does the amount of tooth color change differ between teeth treated with AH Plus and those treated with BioRoot RCS? Does tooth color change over time or differ between the cervical, middle, and incisal regions of the tooth crown? Researchers will compare 66 upper front teeth requiring root canal treatment. Thirty-three teeth will be treated using AH Plus and 33 teeth using BioRoot RCS. Both groups will receive the same root canal treatment protocol, including the cold lateral condensation technique. Participants will: Receive root canal treatment in one visit. Have the color of the treated tooth measured before treatment. Return for color measurements at 1 week, 1 month, 3 months, 6 months, and 12 months after treatment. Tooth color will be measured with a digital device called a spectrophotometer. Measurements will be taken from three areas of the tooth crown to determine how tooth color changes during the one-year follow-up period.
