To Evaluate The Clinical Efficacy Of Modified Root Canal Filling Technique With GuttaFlow2

Objective: To evaluate the clinical efficacy of modified root canal filling technique with Gutta Flow2. Materials and Methods:seventy-five teeth with single root canal and fully formed apices were included in the study. The samples were instrumented using ProTaper rotary file system SX-F3. Following instrumentation the samples were randomly divided into three different groups of 25 root canals each. At the obturating time, The root canals were obturated with cold laterally compacted techniques as the control group, Gutta Flow2 technique and modified Gutta Flow2 technique as the treatment groups. The time consuming during root filling, quality of root filling, postoperative pain responses in one week, and the short time clinical efficacy were chosen as the observation indexes. Results: The root canal filling time of the experimental groups was significantly less than the control group. There were statistically significant differences of postoperative pain response(P = 0.003) and root filling quality(P = 0.021) in the 3 groups,but no statistical significant differences(P = 0.086) were found among the three groups on the short-term clinical efficacy. Conclusion: Root canal filling with Improved Gutta Flow2 obturation technique showed a superior clinical efficacy compared with cold laterally compacted technique concerning improving work efficiency, alleviating postoperative pain response, improving quality of root filling. Improved GuttaFlow2 system is promising in reducing overfilling of the paste when filling with Gutta Flow2, alleviating postoperative pain, which deserves clinical recommending. However,before any definite conclusion can be drawn further studies should be encouraged.
