Simpifil type for canal enlargement by NiTi in:
- a- Universal protaper
- B- Reciprocal ***
- c- Revers S.
The correct answer is B- Reciprocal.
Here's an explanation of the options and why Reciprocal is the most suitable:
- Universal ProTaper:
While a popular NiTi rotary system for canal shaping, it's not designed specifically for canal enlargement. It's more commonly used for full canal preparation.
- Reciprocal:
This system is specifically designed for canal enlargement. It employs a unique back-and-forth motion that effectively removes dentin while minimizing the risk of canal transportation or ledging. This makes it well-suited for shaping curved and narrow canals.
- Revers S:
This system is also designed for canal enlargement, but it uses a different motion pattern (alternating clockwise and counterclockwise rotations). It's a newer system and its long-term clinical outcomes are still being evaluated.
In summary:
- SimpliFill is a technique for root canal obturation that utilizes a single-cone approach.
- For canal enlargement prior to SimpliFill, the Reciprocal NiTi system is generally preferred due to its specialized design and motion pattern that optimizes dentin removal and canal preservation, especially in challenging cases.
Always consult with a qualified dental professional for specific recommendations based on individual patient needs and canal anatomy.
