The Importance of Pericervical Dentin in Endodontics
Modern endodontics aims to save pericervical dentin (PCD) to keep teeth strong and prevent fractures. However, saving too much can block file movement, make apical shaping harder, and reduce irrigation. As a result, treatment may fail more often.
Challenges of Narrow Access Cavities
Narrow access cavities also make cleaning harder by limiting disinfection and increasing tool difficulties. This makes proper shaping and cleaning difficult. Too much dentin near the cervical area can also block file control. As a result, cleaning deep inside the canal becomes less effective.
The Role of Master Apical File (MAF) Size in Treatment Success
Research shows that master apical file (MAF) size affects treatment success. Canals shaped to size 30 or larger heal better. Larger MAF sizes also improve cleaning, especially in necrotic cases with infections. They help irrigation work better and remove more debris. Apical enlargement beyond size 30 improves long-term results by removing bacteria more effectively.
Balancing Dentin Preservation and Effective Shaping
A balanced approach is key in endodontics. Saving dentin is important, but not at the cost of proper shaping and cleaning. Good access and enough enlargement keep teeth strong and improve long-term success.
