Root canal treatment if analyzed mechanically found to be resembling with Injection molding but with high amount of precision. In order to ensure complete success of treatment/manufacturing process, material wastage should be as minimum as possible. In Root canal Treatment (RCT), Gutta-Percha (GP) is used as common filling material which is available in form of solid phase transforming cones which changes its morphology and topology on application of heat and force. Thus, it becomes an uttermost need to determine exact volume of phase changing material with respect to varied geometrical parameters associated with RCT, viz. Canal Curvature, and Canal Operating Length. In this article, author made an effort to develop a methodology to estimate/quantify mass of filler material, GP, and its corresponding specific volume inside the canal using known volume cylindrical canals and standard Endo training blocks having Class II curvatures. The proposed methodology will ensure definite relationship between geometry and material parameters to quantify the specific volume of GP. Thus, the result of this study will be beneficial for the experts from dental fraternity. Also, according to the current study the operational range of force and temperature during obturation can also differ from dentist to dentist. The outcome of presented study clearly indicates that 30% of the cylindrical cavities are under-filled wherein in Endo training blocks almost 100% canals are under-filled which may results due to high amount of process parameters and can lead to irreparable damage of canal. The existence of unfilled cavities at the coronal aperture is due to variances in clinical technique across specialists, as indicated by the obturated cylindrical cavities. © 2022
