Analysis of Microbiological Results in Teeth with Chronic Apical Periodontitis
Angela Gusiyska, Stefan Peev
Abstract: The invasion of the living microorganisms and their toxic products in endodontium and periapical structures is a significant problem in chronic apical periodontitis (CAP). This study analyzed the microbiological results of teeth with CAP. Microorganisms were isolated from the infected root canals of teeth with chronic apical periodontitis (primary or secondary) with or without the absence of clinical signs and symptoms. The microbiological diagnosis was made based on 79 teeth from 79 patients who fulfilled the inclusion criteria (n=79, 38 single-rooted and 41 multi-rooted teeth/36 females and 43 males) with an average age of 40 years (age range = 1862). The study investigated teeth with CAP with or without an endodontic treatment. The data was inputted and processed using statistical package SPSS 15.0.1. E. faecalis was the most frequently isolated microorganism (68.6 %). The analysis of microbiological results in primary CAP (Group II) showed that there were no isolated microorganisms in 78.6 % of the cases (22 cases). In contrast, in Group I, the first microbiological sample results were positive, with bacterial growth at 92.2 % (47 cases). E. faecalis is a typical microflora in persistent CAPs performed with unsatisfactory endodontic treatment, and it is not isolated from teeth with primary CAP. E. faecalis is a resistant microorganism even after the application of chemomechanical preparation of the endodontic space.
