Access Cavity and Working Length Determination. Hands-On Course with Arnaldo Castellucci

Successful endodontic treatment begins long before instrumentation — it begins with precision. The accuracy of working length determination and the quality of the access cavity dictate everything that follows: cleaning, shaping, irrigation, Obturation, and ultimately the prognosis of the tooth.

Under the guidance of world-renowned endodontist Arnaldo Castellucci, participants will explore the refined use of ultrasonic tips to perfect the endodontic access cavity, as well as the clinical power of next-generation apex locators to correctly interpret readings, understand measurement behavior within complex canal systems, and confidently determine the true working length.

Practical training includes:

— Clinical use of next-generation apex locators
— Determination and interpretation of working length measurements
— Understanding apex locator signals and readings in different clinical situations
— Ultrasonic refinement of the endodontic access cavity
— Improving visibility and precision through ultrasonic instrumentation
— Access correction for safer and more controlled canal treatment.

This is not just about using devices — it is about understanding what the numbers mean, what the signals hide, and how subtle refinements in access design can transform the entire outcome of endodontic treatment.
