Woodpecker Woodpex III Dental Apex Locator

Woodpex III Professional Apex Locator Core Advantages

• Adopts advanced multi-frequency apical positioning technology to maintain precise measurement even with blood or residual pulp tissue inside root canals
• Measurement data remains stable and accurate without interference from different tooth types, suitable for all anterior and posterior teeth

Upgraded Chip & Algorithm Boost Accuracy To 97.71%

Woodpex III is equipped with an upgraded high-speed processing chip for instant real-time data response, doubling overall detection sensitivity. The innovative multi-frequency algorithm delivers powerful anti-interference performance, lifting clinical measurement accuracy rate up to 97.71% for reliable endodontic treatment.

Clinical Comparative Test Against US & Japanese Brand Apex Locators

A rigorous controlled clinical test was conducted to compare measurement accuracy between Woodpecker Woodpex III, mainstream American brand D and Japanese brand S apex locators. The test materials contained 97 teeth diagnosed with pulpitis and apical periodontitis, totaling 175 independent root canals. After standard initial canal shaping, three devices measured working lengths separately, with X-ray imaging as the reference standard to verify measurement precision. The test results fully prove Woodpex III’s outstanding positioning accuracy among mainstream apex locator products.

Limitations of Traditional Manual Working Length Measurement

Traditional hand-feel measurement relies entirely on the dentist’s subjective judgment and patient pain feedback to judge when the file reaches the apical foramen, leading to severe inaccuracy. According to authoritative international dental literature, manual measuring only achieves a 42% accuracy rate within the ±0.5mm acceptable error range, which greatly raises risks of apical perforation or under-preparation.

Shortcomings of Single X-Ray Film Length Measurement

• X-ray captures complex 3-dimensional root canal structures onto a flat 2D plane; shooting angle deviation easily causes false length data
• Over 80% of natural apical foramens open on the lateral root wall instead of the root tip, making them invisible on standard X-ray films and resulting in misjudgment of true working length
