Digital Radiography (DR) has gained popularity as a replacement for CR because it offers better image quality and enables the dentist to do radiographic exams with less radiation exposure. Conclusion: For root canal treatment, radiographic diagnostic value is essential. Additionally, this technique is utilized to find procedural errors, resorptive defects, and fractures.
