Study Notes
Radiographs in Endodontics
- Radiographs are essential for diagnosis, treatment planning, and monitoring endodontic treatment.
- They are the primary diagnostic tool for identifying pathosis and determining root and pulpal anatomy.
- A single exposure is often sufficient, but a properly positioned film and cone allow visualization of at least 3-4mm beyond the apex.
Types of Radiographs
- Pre-operative/Diagnostic radiograph: used to detect pathosis and provide general information on root and pulp anatomy.
- Working radiograph: used to establish working length, verify tooth anatomy, and monitor treatment progress.
- Obturation radiograph: used to evaluate endodontic treatment, especially obturation length and quality.
- Follow-up/Recall radiograph: used to determine the success of therapy and monitor healing.
Master Apical File (MAF)
- The MAF is the largest file that binds slightly at the corrected working length.
- It is determined by passively placing successively larger files at the correct working length until a size is reached that slightly binds at the tip.
- The MAF size is recommended to be three sizes larger than the Initial Apical File (IAF).
- For large canals, a minimum MAF size of #40-50 is recommended, and for small canals, a minimum MAF size of #35-40 is recommended.
