Abstract
A systematic approach to endodontic clinical assessment, case complexity evaluation and precise diagnosis is essential for achieving successful endodontic management and favourable treatment outcomes. Neglecting these foundational elements can jeopardise the entire treatment process. This article is part of a themed issue dedicated to endodontics and serves as a practical guide for clinicians, outlining the comprehensive process of endodontic assessment. It will encompass clinical examination, radiographic interpretation and diagnostic testing, ultimately providing clinicians with the necessary tools for accurate diagnosis and effective treatment planning.
