Introduction: endodontics employs irrigants such as sodium hypochlorite and chlorhexidine to disinfect root canals, although their inappropriate use may cause clinical accidents with significant consequences for patient health.
Objective: to analyze the prevalence, complications, management, and preventive measures regarding accidental extrusion of endodontic irrigants among dentists in Ambato, Ecuador.
Methods: a quantitative, descriptive, non-experimental, cross-sectional study was conducted in 2024. Thirty dentists participated through convenience sampling. A structured questionnaire with closed and open-ended questions was administered electronically. Data were processed using descriptive statistics, respecting bioethical principles of informed consent and confidentiality.
Results: a total of 46,6 % of dentists reported having experienced irrigant extrusion. The most frequent complications were pain (43,3 %), edema (26,6 %), and bone necrosis (23,3 %). Management measures included rinsing with water (26 %), use of anti-inflammatory drugs and antibiotics (16,7 %), and suspension of irrigation with rest (16,7 %). For prevention, participants highlighted the importance of applying proper irrigation techniques (36,6 %) and controlling volume and pressure (23,4 %). The most frequently mentioned risk factors were complex canal anatomy (36,6 %) and iatrogenic perforations (22,4 %).
Conclusions: the study shows that irrigant extrusion is a frequent and potentially serious clinical event. The findings emphasize the need for continuous training, standardized protocols, and safe technologies to reduce risks. Identifying predisposing factors helps guide preventive strategies and improve safety in endodontic procedures, thereby strengthening the quality of dental care.
