Objective: This study aims to investigate the causes of endodontic complications, develop evidence-based preventive strategies, and assess their impact on treatment outcomes to enhance the quality and success of endodontic procedures Methods: A cross-sectional study design will be implemented to examine the etiology of endodontic complications, identify preventive strategies, and evaluate their effect on treatment outcomes. This approach facilitates the collection of data from a diverse sample at a single point in time, offering a snapshot of the current situation. Results: The study comprised 667 participants. The most represented age group was over 45 years (n=157, 24%), followed by those aged 25-30 years (n=142, 21.3%). Females were the majority among the participants (n=364, 54.6%), with males constituting 45.4% (n=303). The highest educational level was a diploma or bachelor's degree (n=455, 68.2%), and the next was high school (n=126, 18.9%). When it came to income, most participants were in the middle bracket (n=507, 76%), with the high-income bracket next (n=85, 12.7%), and the lowest income bracket was the least common (n=75, 11.2%). Regarding satisfaction with their root canal treatment, most participants reported being very satisfied (n=226, 34%), with a neutral response as the next most frequent (n=202, 30%). In terms of complications, the largest group of respondents did not know which complications they encountered (n=334, 46.3%), followed by those reporting pain after surgery (n=242, 33.6%). The most cited source of information was the dentist (n=285, 42.7%). Conclusion: The results suggest that the study's participant demographic primarily included middle-income individuals with at least a diploma or bachelor's degree. Information about endodontic treatments was predominantly provided by dentists. Participants generally reported high satisfaction with root canal treatments and demonstrated robust social communication.
