Endodontology referred to as Root Canal Treatment (RCT) is a field of science that deals with the entire chemo-mechanical cleaning and sealing of the root canal system by using restorative material used to rescue or repair severely decaying or diseased teeth. The success of the treatment depends on the seal formed between the filling material and the root cavity post-obturation. The crucial components include the energy used to clean and seal the root canal system, the material used to fill the root canal system, the process used to fill the root canal system, and the geometry of the root canal system. In the presented research, ideal operative parameters and their interaction were studied with 32 experimental trials for five operative parameters namely canal angle, canal operative length, compaction force, operative temperature, and operating frequency using central composite rotatable design (CCRD); a response optimization tool. The treatment was carried out on endo-training blocks prepared with a 6% uniform taper across the working length by using gutta-percha as filling material. A compaction force of 10N, operating temperature between 90-92° C, operating frequency in the range of 40-50 Hz, and operative length of 12mm results in maximum gutta percha compaction.
