“…6 Cross sectional studies have reported 20%-60% of treatment failure and 52% of endodontic failure in Iranian population. [7][8][9][10] Existence of intracanal microorganisms would lessen the treatment outcomes of endodontic re-treatment comparing to primary endodontic treatment. 2 Based on the previous studies, bacterial microflora in teeth with failed endodontic treatment is different from the microflora of the primary endodontic infection.…”

IntroductionMicrobial infection plays an important role in persistent periapical lesions.1 Insufficient disinfection of root canals could lead to treatment failure and persistent periapical pathology. 2Conventional techniques of root canal treatments such as mechanical instrumentation and chemical debridement with antimicrobial irrigants, such as sodium hypochlorite (NaOCl), chlorhexidine and calcium hydroxide do not always suffice to predictably render root canals free of bacteria.3,4 Factors such as anatomical complexities, bacterial growth as biofilm, render complete disinfection of the root canal system almost impossible. 5Studies have revealed a success rate of 94% with a negative culture before obturation has decreased to 68%, with a positive culture.2 Resolution of periapical lesions is more achievable when there is negative culture before obturation. 6Cross sectional studies have reported 20%-60% of treatment failure and 52% of endodontic failure in Iranian population.7-10 Existence of intracanal microorganisms would lessen the treatment outcomes of endodontic re-treatment comparing to primary endodontic treatment. 2Based on the previous studies, bacterial microflora in teeth with failed endodontic treatment is different from the microflora of the primary endodontic infection. All culture and PCR based methods have shown that primary endodontic infection is a polymicrobial infection involving fully anaerobic microorganisms, 5,11 while the failure AbstractIntroduction: The aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (PDT) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. Methods: In this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. After conventional chemo mechanical preparation of root canals, microbiological samples were taken with sterile paper point (PP), held in thioglycollate broth, and then were transferred to the microbiological lab. In the first group, PDT with methylene blue (MB) and diode laser (810 nm, 0.2 W, 40 seconds) was performed and in the second group diode laser (810 nm, 1.2 W, 30 seconds) was irradiated. Then second samples were taken from all canals. Results: CFU/ml amounts showed statistically significant reduction in both groups (P < 0.001). CFU/ml amounts were compared between the two groups and there was no statistical difference. Conclusion: PDT and diode laser 810 nm irradiation are effective methods for root canal disinfection. PDT is a suitable alternative for diode laser 810 nm irradiation, because of lower thermal risk on root dentin.

“…In the evaluation of the quality of RF, various criteria were used in the selected studies: three studies used the distance of the endodontic filling from the root apex, 16,21,23 three studies used the filling density and its distance from the apex, 17,18,25 three studies defined the parameter as being the presence of filling material in the root canal 1,9,19 four studies preferred criteria proposed by other authors 20,22,26,27 and in one article the authors created their own guidelines 24 ( Table 1). …”

The aim of this study was to investigate the relationship between root fillings and the presence of apical periodontitis in studies with samples containing elderly patients. The data were obtained by means of a systematic review of studies that evaluated the quality of root fillings and their relationship with periapical health. 1,376 potentially relevant articles were selected, of which 667 were repeated and 16 were duplicates. 693 abstracts were analyzed, with 608 of these being excluded and 85 selected for reading in full. Fourteen (14) articles were included, totaling data of 135,566 teeth. Of these, 13,704 (10.1%) had endodontic fillings, with 6,455 (47.1%) being considered adequate and 7,249 (52.9%) inadequate. Among the teeth with apical periodontitis, 2,084 (32.3%) had adequate endodontic fillings and 3,749 (51.6%) had inadequate fillings. There was a significant correlation between the quality of endodontic fillings considered adequate and lower frequency of apical periodontitis in elderly patients.

“…However, some studies have reported an increased prevalence of apical periodontitis in teeth restored with clamps [9]. In a study carried out by Tavares et al [19], out of 458 teeth with dental post, 315 (65%) teeth were involved with chronic apical periodontitis.…”

“…The data obtained from Scandinavian and other European countries has shown a high prevalence of apical periodontitis due to the poor quality of root canal treatment [5][6][7][8][9][10][11]. On the other hand, apical periodontitis usually occurs as a chronic disease and has few or no clinical symptoms [5,12].…”

Since the discovery of the high prevalence of chronic apical periodontitis in many countries as an important risk factor for public health, numerous epidemiologic studies have been conducted to analyze its prevalence and the factors associated with it [1][2][3][4]. Generally, it has been accepted that the result of endodontic treatment is positively associated with the quality of root canal filling techniques, which consequently leads to sealing and preventing the penetration of bacteria into the root canal system. Epidemiologic studies have associated the prevalence of apical periodon- AbstractBackground. A lot of research has been done on the prevalence of apical periodontitis in different populations, but there is no data on its prevalence in Iranian population, so there is not enough data about this condition and the factors associated with it. Objectives. The current study was aimed to evaluate the prevalence of chronic apical periodontitis among the patients visiting the Department of Endodontics at the Kermanshah School of Dentistry. Material and Methods. This descriptive cross-sectional study was carried out on 595 patients (252 men and 343 women) who were referred to the Kermanshah School of Dentistry in 2014-2015. First, the patients' demographic data was taken using a checklist. Then, an OPG x-ray of each patient was observed carefully and the location of chronic apical periodontitis in the jaws, the history of endodontic treatment, the presence of dental post, adequate and inadequate restorations and periapical index (PAI) were recorded on a checklist. The collected data was analyzed using SPSS-18 software.Results. The prevalence of chronic apical periodontitis was reported to be 4.4%, which increased with age. It was higher in men than in women. The most common site of apical periodontitis was the maxilla and the highest incidence was reported for posterior teeth. Conclusions.The findings of the current study indicate a high prevalence of chronic apical periodontitis due to the presence of post and a history of inadequate root canal treatment (Dent. Med. Probl. 2016, 53, 4, 496-500).
