A mathematical model for root canal preparation using Endodontic file

Abstract

To develop the mathematical model for root canal preparation using Endodontic file. Method: The process of obturation consist of the filling of the root canal cavity using heated and softened guttapercha to get the fluid tight seal in between the canal wall and filled gutta-percha. Any obturation process to perform before it requires the preparation of the root canal which involves the removing dead tissue, substrates and debris from the decayed root canal. The various geometric parameters viz. Taper, relative angle for orientation of cross-section between two planes, pitch and polar symmetry constant of the Endodontic file etc. Geometric parameters are derived. The various performance parameters like Endodontic file life assessment, cutting force components (tangential and normal), substrate removal rate, torque exerted by Endodontic file etc are also derived successfully. The Endodontic file life is estimated based on two approaches viz. speed and volumetric wear approach. Conclusion: The mathematical model described is helpful for the Endodontic experts, researchers, design engineers etc. However the applicability of the described mathematical model limited to assumption of study. The gap between root canal to be prepared and Endodontic file is zero while preparation. The Endodontic file weight, speed of rotation and substrate removal rate is assumed to be constant. The mathematical model for Endodontic file discussed above proved to be efficient tool for studying the root canal preparation. The various geometric parameters and the various performance parameters are derived.

The quantification of percentage filling of gutta-percha in obturated root canal using image processing and analysis

“…7 The past endodontic studies performed qualitative assessment of obturated root canal (Amir moinzadeha at al., 2015; Nicola maria grande et al, 2015; Pravin R. Lokhande et al, 2020) . [8][9][10] But the assessment depends on Dentist's experience and perception. Therefore, there is need of quantitative assessment of percentage filling of obturation material in obturated root canal.…”

Flow, Filling Ability and Apical Extrusion of New Calcium Silicate-Based Sealers: A Micro-Computed Tomographic Study

“…Root canal treatment is performed aiming to save teeth [1]. Since a threedimensional root canal sealing is essential for the success of endodontic therapy, root canal sealers should present flow, aiming to fill the anatomical complexities of the root canal system [2,3].…”
