Why X-rays Are Vital In Root Canal Treatments | BEFORE & BEYOND EP46

Dr Ho Ying Yao explains why X-rays are essential in root canal treatment. He demonstrates how 2D and 3D imaging guide cleaning, detect hidden canals, and ensure complete disinfection

About The Video

In this video, Dr Ho Ying Yao uses a home plumbing analogy to describe root canal treatment. Just as a clogged pipe can be cleaned instead of replaced, a tooth with internal infection can be preserved by cleaning and sealing its root canal. He explains how X-rays are used before and during treatment to identify canal shape and number, helping dentists plan an accurate and thorough procedure.

Dr Ho Ying Yao presents a case showing how a suspected second canal was confirmed using angled X-rays. He highlights how 3D imaging, such as CBCT scans, provides a clearer view of complex root structures, particularly when canals branch or diverge. These tools make treatment more predictable and improve long-term outcomes. The video emphasises that detailed imaging is key to achieving complete disinfection and preventing reinfection

Root canal treatment is designed to save a tooth with internal infection by cleaning out bacteria and sealing the space to prevent reinfection. Successful treatment relies on accurately locating all canals, as missed branches can lead to persistent pain or failure. Traditional 2D X-rays help identify the main canal structure, but certain teeth, especially premolars and molars, often contain hidden or curved canals that are difficult to detect.

Advanced imaging like 3D cone-beam computed tomography (CBCT) provides a more complete picture, revealing complex canal systems and divergences. This allows for more precise instrumentation and filling, reducing the likelihood of missed infection. X-rays taken before, during, and after treatment also guide length measurement and ensure full cleaning to the root tip. By combining modern imaging with skilled technique, dentists can preserve natural teeth more reliably and with better long-term results.
