Ab s t r Ac t Aim: The present study aims to assess the knowledge of some endodontic concepts, working width (WW) vs working length (WL) and variable taper vs constant taper among endodontic practitioners. Materials and methods: A descriptive study design was employed to assess the knowledge and understanding of endodontics practitioners. The questionnaire was distributed among 400 participants, which was composed of different items and was measured using different rating scales. Results: Descriptive statistics were presented in tables based on the frequency and percentages of responses from participants. Out of 400 participants, 363 responses were obtained. The results showed that the radiographic method and the electronic method were both useful for determining the WL during root canal treatment. Moreover, a majority of the participants preferred to use WL with 0.5 mm shorter than apex, while a few of them preferred 1 mm shorter than the apex. The significant factors that help in determining the WW and length included canal taper, canal morphology, and canal curvature. Conclusion: The study results have concluded that both the radiographic method and the electronic method are useful in determining the WL. Canal geometry and morphology were among the factors that influence the WL detection method.
