[2025-10-01T09:57:00.863074] [PI reasoning] **Analyzing radiographic methods**

The user wants to know about the current radiographic method for determining working length in endodontics. The options include Grossman, Ingels, and Bregman techniques. I realize that Grossman’s technique is indeed a radiographic method, but Ingle's method (not Ingels) is historically more commonly used for measuring working length. By subtracting 1 mm from the file measurement, Ingle's technique is practical. I believe the correct answer is B: Ingle's technique, but I’ll double-check.
