Introduction: apical locators represent a fundamental innovation in endodontic practice, allowing a more precise determination of working length and reducing clinical complications associated with root canal treatment.
Objective: to analyze scientific evidence on the importance, functions, and limitations of apical locators in dental practice.
Methods: a bibliographic review was conducted through the implementation of a search algorithm across different databases, applying established selection criteria. The analysis focused on reported accuracy, advantages, and limitations.
Development: apical locators have evolved from systems based on electrical resistance to multi-frequency devices with high clinical accuracy. Advantages include reduced radiographic exposure, ease of use, and the ability to measure in moist canals. However, limitations are reported in teeth with open apices, metallic crowns, pacemaker interference, and morphological variations. Comparative studies show that devices such as root zx and apit provide reliable results, although influenced by irrigants and specific clinical conditions. Current trends highlight the integration of these devices as indispensable complements to endodontic treatment.
Conclusions: apical locators are electronic tools of great value for improving diagnostic and therapeutic precision in endodontics. Their use complements radiography, reduces risks of over-instrumentation, and strengthens professional training, consolidating them as an essential resource in contemporary dentistry.
