The triad of endodontics is incomplete without the vital step of obturation. The success of an endodontically treated tooth vastly relies upon achieving a "fluid tight seal" carrying out an obturation adequately and accurately. Choosing a particular technique among several obturation techniques available is based upon the anatomy of the root canal and achieving certain objectives specific to each case. The two basic obturation procedures are lateral condensation and warm vertical compaction. There has been an advent of newer devices and techniques, such as those which employ heat and vibration for condensation and compaction of the obturating material, dramatically transforming the practice of endodontics and making success of an obturation more predictable. This article briefly covers the obturating materials and the techniques used for obturation along with their present status in today's endodontic practice.

This research article focuses on the design, fabrication and analysis of firewater storage tank in order to assess tank integrity and maintaining compliance with industry and regulatory standards. The storage tank is considered of fixed cone roof firewater tank considering carbon steel as the material of the tank. The analysis has been carried out using CFD and finite element analysis. The results of the study shows that the designed tank is safe from the failure mode and the seismic energy transferred and accumulated in the structure.
