RADIOGRAPHIC OUTCOMES AND ETIOLOGIC FACTORS OF APICAL PERIODONTITIS AFTER ROOT CANAL THERAPY

Aim of the study This study aimed to evaluate the incidence of radiographically evident apical periodontitis following conventionally performed endodontic treatments, with a focus on the role of clinical experience and the identification of contributing iatrogenic and diagnostic factors. Materials and methods A cross-sectional study was conducted on a sample of 100 dental professionals, including both practicing dentists and dental students. Data were collected through a structured questionnaire addressing clinical experience, incidence of apical periodontitis, common iatrogenic errors, and the role of radiologic follow-up. The psychometric validity of the questionnaire was assessed, and statistical analysis was performed on collected responses. Results The majority of experienced practitioners (>5 years) reported more frequent encounters with apical periodontitis and better healing outcomes after conventional treatment. Incomplete endodontic treatments were more commonly observed among less experienced clinicians, with key errors including inaccurate working length determination, overfilling, and presence of foreign objects. Radiographic follow-up, particularly with CBCT, was more prevalent among experienced dentists and correlated with improved diagnostic accuracy and post-treatment assessment. Conclusions Clinical experience is a key determinant of successful endodontic outcomes. Apical periodontitis remains a prevalent issue, particularly in complex root canal systems. Technical proficiency and the use of advanced imaging tools like CBCT are crucial in preventing treatment failures and ensuring adequate periapical healing.
