Specifications:
Minimum size for the glide path is ISO 15/.02. The BT-Race sequence requires this minimum size before use. Instruments such as BT4, BT5, BT2, and BT3 have specific size and taper specifications.

Procedures:
1. Establish a glide path before using the BT-Race sequence.
2. Use BT40 or BT50 for larger apical sizes.
3. Each instrument should be used to the full working length (WL) before switching to the next. The total working time per canal should not exceed 10 seconds.
4. Use BT1 with a long and gentle pecking motion (3-4 back and forth strokes). If the instrument does not reach WL, clean it, irrigate, and repeat until WL is achieved.
5. Recapitulate with a K-File ISO 15.
6. Use BT2 and BT3 in the same manner as BT1.

Operating Parameters:
All instruments should operate at 800 rpm (range 600-1,000) with a torque of 1.5 Ncm.

Recommendations:
For most cases, follow the BT-Race protocol to ensure effective and efficient use of the instruments.
