The DPEX V is the Fifth Generation Apex Locator from DBA, designed for accurate and simple electronic measurement of the root canal length in dentistry.

Key Features:

• Advanced Technology: It incorporates a new digital circuit, an industry-recognized U.S. central processing chip, and high-precision components from Japan. It features multi-frequency apex positioning technology combined with a DSP data processing system and clinical big data to eliminate interference and ensure accurate measurement, even with residual pulp and blood present.

• Intuitive Display: The device has an optimized and upgraded LCD display with bright, glare-free light, presented in a "Black gold" aesthetic. It offers a clear view of the file's position in the root canal, including a zoom on the apical $1/3$ narrow part for more intuitive measurement.

• Acoustic Guidance: The system provides three distinct sound prompts to guide the user:

  • Low-frequency "beep" when the file is approximately 1/3 of the way into the canal or less than 2mm from the apical foramen.

  • Continuous high-frequency "beep" when the tip reaches the preset position of the apex stop.

  • No sound, with a red indicator, when the file exceeds the apical foramen (0.0 mark).

• Usability: It features an automatic calibration during a 0.5s booting time, a preset apical stop function (settable from 0.0 to 1.0), adjustable alarm volume, and a short-circuit test reminder.
