Analysis Of Scanning Electron Microscopic Examination Of The Apical Zone Of Teeth With Chronic Apical Periodontitis - An Ex Vivo Study

Key stages in the treatment of chronic apical periodontitis (CAP) are the assessment of the status of the periapical zone, effective decontamination and subsequent sealing of the root canal space. The aim of this article is to analyze electron microscopic results from periapical zones examination in extracted teeth. The apices of 43 teeth (n = 43) were examined, allocated in two groups. After resection, the apices were fixed to stands for SEM-examination. Based on the analysis of the results, the following conclusions can be drawn: an external resorption around the apical foramen is established in 97.6% of cases in the teeth with radiographically diagnosed CAP.
