Factors affecting the periapical status of root-filled canals – a cross-sectional study at the undergraduate level
Cross-sectional studies aim to evaluate the health status of a population as well as to measure the prevalence of disease or efficacy of the treatments [1]. In therapeutic terms, the oral functions of billions of teeth are preserved through root canal treatment [1, 2]. After shaping, root canal filling, and coronal restoration, the tooth should resume its functions within the oral cavity [3, 4]. At the same time, the previous periapical lesions should be repaired, and this normality should be maintained for a long time [5, 6]. However, no contemporary endodontic treatment protocol ensures 100% clinical and radiographic success [7-10]. In addition, several oral cavity factors may put the success of endodontic treatment at risk [5, 9-11].
In epidemiological terms, the predominance of low technical-quality endodontic treatments is associated with a high prevalence of apical periodontitis [6, 11-13]. Thus, deficient root canal instrumentation would lead to filling failure and, consequently, to the continuity of periapical lesions [11, 13, 14]. Adequate coronal restoration blocks microorganisms and the access of fluids to the root canal in endodontically treated teeth [10]. Coronal-sealing disruption favors microbial recolonization in the root canal and leads to endodontic treatment failure [3, 15]. However, other studies have found no correlation between the quality of coronal restorations and periapical status [14, 16]. With regard to dental caries, an [...]
