Summary Introduction The main objective of endodontic treatment is to eliminate infection from root canal and prevent reinfection by three-dimensional hermetic obturation of the canal system. Endodontic failure can occur due to inability of complete control and elimination of infection from the root canal. The aim of this study is to investigate, by PCR technique, microbiological status of previously endodontically unsuccessfully treated teeth immediately after the removal of obturation material. Material and Methods The analysis included 30 teeth indicated for endodontic retreatment. After removing previous root canal filling material, the bacteriological sample was taken by sterile instrument (# 15) and paper points. Standard PCR technique was used to analyze the incidence of E.faecalis, P.micros, P.intermedia, P. endodontalis and A.actinomycetemcomitans. Results Positive bacteriological findings were registered in 80% of cases, while bacteria were not identified in 20% of all samples (all taken from the root canals without significant changes in periapical tissue). From 24 canals with identified bacteria, 17 had affected apical periodontium. The most dominant microbe in root canals with positive bacteriological finding was E.faecalis (83.3% of the canals) and P.intermedia (75%). In case of teeth with chronic periapical changes, the most common was E. faecalis (94%) and P.intermedia (82.3%). Conclusion The presence of periapical lesions significantly affects microbiological status of endodontically treated teeth. The presence of bacteria was confirmed in most teeth with periapical lesions, while the most frequently identified bacteria were E. faecalis, P.intermedia and P.micros.

Introduction. The main goal of obturation is prevention of reinfection of the root canal system and consequently appearance of periapical lesion. Epidemiological studies have confirmed high prevalence of periapical lesions in endodontically treated teeth with inadequate root canal fillings. The aim of this study was to assess the quality of root canal fillings in teeth treated at students? practical sessions. Iatrogenic errors during endodontic interventions were also assessed. Methods. Two hundred dental records of the patients treated by students in the study program Dentistry at the School of Medicine in Foca during the academic year 2010/2011 were randomly chosen. The length and homogeneity of the fillings or the presence of iatrogenic errors were recorded. A root canal filling was considered adequate if it had correct length and homogeneity in the absence of iatrogenic errors. Two students? curricula V1 and V2 were evaluated for the treatment outcome. Results. Out of 128 endodontically treated teeth, adequate length of the canal filling to the physiological apex was observed in 57% of teeth, homogeneity in 78.9%, while both of these criteria were satisfied in 66 teeth (51.6%). Better quality of root canal fillings was achieved by students of the study curricula V2 and the difference between these two programs was significant (p<0.05). Better quality of root canal fillings in both study programs was recorded for incisors and canines as compared to premolars. Conclusion. The quality of endodontic treatment performed by students was considered adequate in 51.6% of cases. The type of curriculum for endodontic course had a significant impact on the quality of endodontic treatment performed by students.

ABSTRACT Objective: The purpose of this study was to evaluate the incidence of endodontic treatment and the quality of root canal fillings in Brazilian undergraduate dental students. The study was similar those conducted 10, 20, 30, and 40 years earlier. Methods: A total of 407 undergraduate dental students were evaluated by using questionnaires to identify endodontic treatments, with each treatment being radiographed for the analysis of the presence of a periapical radiolucency and the quality of the root canal filling. Results: Forty root canal fillings were found: 32 (80%) completely filled, seven (17.5%) incompletely filled, and one (2.5%) overfilled. Conclusion: This study showed a low prevalence of endodontic treatment in dentistry students, and the evaluated root canals that were filled were high quality, with few cases suggesting periapical lesions.

Background: One of the key factors in successful endodontic therapy is to adequately fill the root canals. Vertical condensation technique is regarded as a high probability of three-dimensional filling of root canal space which is required to achieve long-term success. Aim: To evaluate the endodontic treatment outcomes of vertical condensation technique using Touch’N Heat device. Subjects and methods: A prospective, descriptive study was conducted across two hospitals in Hue city from 11/2016 to 5/2017. All teeth were instrumented by manual Protaper files and obturated by the vertical condensation technique with Touch’N Heat device. The radiographic evaluation for initial assessment of obturation quality was performed. Evaluation of endodontic treatment outcomes in terms of clinical symptoms and radiographic assessment were recorded after 3-month follow-up. Results: A sample of 30 patients (with 39 incisors) from 13 to 73 years old was recruited. The principal reasons for visiting were pain (30.8%), decay (20.5%) or trauma (20.5%). Most patients seeked treatment at chronic stage of diseases with chronic pulpitis (38.4%) and chronic periapical periodontitis (30.8%). In radiographical quality of obturation, there were 27 (69.3%) fulllength obturated teeth, 8 (20.5%) overfilled teeth (sealer). The percentage of homogeneity of root canal filling was 82.1%. Over 82% patients (25 patients with 32 teeth) presented after there-months followup. Clinical assessment yeiled 30 (93.7%) “adequate” teeth, 2 (6.3%) “poor” teeth. Refer to radiographical assessment, the teeth were defined as “success”, “questionable” and “failure” (29 teeth (90.6%), 3 teeth (9.4%) and zero, respectively). Conclusions: The vertical condensation using Touch’N Heat device ensure the full-length obturation, high homogenetious root canal filling, and sucessful prognosis in clinical and radiographic outcomes. Key words: vertical condensation,Touch’N Heat, endodontic outcomes

This study aimed to assess the periapical status and the quality of root canal filling of endodontically treated teeth from cone-beam volume tomography (CBCT) images.Of 66 teeth (124 root canals) that received root canal treatment, the quality of the root canal filling as well as the periapical status were assessed using cone-beam volume tomography (CBCT). Radicular obturation on an X-ray image was defined as satisfactory if it is 0-2 mm from the radiographic apex without voids. On CBCT scans, the apical end of the canal has replaced the radiographic apex.The present study showed, according to the periapical status, 87.9% (n = 109) of the canals exhibited a periapical lesion. The 1, 2, and D scores of the CBCT PAI were more met with respectively 46, 19.4%, and 8.9%. The association between the lengh of root canal filling and the presence of apical radiolucency showed a significant relationship (p = 0.02). The presence of apical radiolucency is also very significantly associated with the inadequate density of root canal fillings (p = 00003).The present study confirms, by CBCT, that the presence of periapical lesions was associated with poor quality obturation technique.

Objective: The aim of this study was evaluate radiographically prevalence of apical periodontitis (AP) in endodontically treated teeth (ETT) and relate with demographic factors, quality of endodontic treatment and coronal restoration. Material and methods: Data were collected from dental records wich contained full-mouth radiographic series. In ETT, arch, dental group and presence of AP were evaluated. Quality of root canal filling, presence and quality of coronal restoration and type of restorative material were also collected. Data were evaluated using descriptive statistics and Chi-square Test. Results: Of 70 patients included in the final sample, the majority were female (54.3%) and age ranged from 13 to 77 years (47.14 ± 13.18). Of 1,333 teeth evaluated, 73 (5.4%) had endodontic treatment, being the majority maxillary (74%) and anterior teeth (52.1%). Of teeth without endodontic treatment, 320 (25.4%) had AP. Failure rate was high (52.8%) and quality of root canal filling and coronal restoration were considered inadequate in majority cases (58.3% and 47.7%, respectively). Dental group had a statistically significant relationship with presence of AP in ETT, being more frequent in anterior teeth (p = 0.019). Conclusion: It was concluded that prevalence of AP in ETT was high and dental group was the factor that most influenced prevalence of AP in ETT.KeywordsApical periodontitis; Radiography; Root canal filling.

ABSTRACT Aim To evaluate the effectiveness of ProTaper universal retreatment system in the removal of root canal filling material with thermomechanical compaction, in comparison to manualmechanical technique, associated with orange oil or eucalyptol. Materials and methods Forty extracted lower incisors were filled with thermomechanical compaction technique. After 3 years, the root canal filling was removed by: G1 - manualmechanical technique with orange oil; G2 - manual-mechanical technique with eucalyptol; G3 - ProTaper universal retreatment system with orange oil and G4 - ProTaper universal retreatment system with eucalyptol. In sequence, all root canals were instrumented to F5 instrument. The teeth were longitudinally grooved, images of buccal half were obtained in stereomicroscope and covered area by root canal filling material was measured using image tool software, in cervical, middle and apical radicular thirds. The results were subjected ANOVA and Tukey test (p = 0.05). Results In all thirds, the manual-mechanical technique showed lower presence of root canal filling material on root canal dentin in comparison to ProTaper retreatment universal system, regardless of organic solvent used (p < 0.05). There is no difference between organic solvents in removal root canal filling material (p > 0.05). Conclusion The ProTaper universal retreatment system showed lower effectiveness in removal root canal filling material than manual-mechanical technique, regardless of organic solvents (orange oil or eucalyptol oil) used. Clinical significance Recently rotary instruments have been proposed to removal of root canal filling material. However, there are no studies evaluating its effectiveness in removal root canal filling material in association with orange oil or eucalyptol oil.

<p><strong>Objective: </strong>Failures in endodontic treatment may occur by several reasons. Endodontic retreatment is an interesting alternative to manage this clinical problem. However, it is not possible to completely remove the root canal filling by any current retreatment technique. The aim of this study was to evaluate the presence of residual root canal filling materials after endodontic re-instrumentation. <strong>Material and Methods:</strong> Sixty extracted anterior human teeth were prepared by step-back technique with Flexofiles, K-files and Gates-Glidden (GG) burs. Between the use of each file or bur, root canals were irrigated with sodium hypochlorite (NaOCl). Smear layer was removed by irrigation with ethylenediaminetetraacetic acid and NaOCl. After drying with paper points the root canals were randomly divided into 5 groups (n = 12), according to filling material: Resilon cones/Real Seal sealer or gutta-percha cones and Endofill, Sealapex, AH Plus or MTA Fillapex sealers. After one week, root canal fillings were removed using Eucaliptol and K-files. Root canals were re-instrumented with K-files and GG burs sized larger than the first ones. The removal of root canal filling material was analyzed by radiography and scanning electron microscopy (SEM). Statistical analysis was performed using Binary Logistic Regression test (P &lt; 0.05). <strong>Results: </strong>Radiographic and SEM analysis showed that material from the<strong> </strong>MTA Fillapex group was better removed than that from Endofill, Sealapex, AH Plus and Real Seal groups. <strong>Conclusion: </strong>After re-instrumentation<strong>, </strong>MTA Fillapex group showed less remnants into the root canals than Endofill, Sealapex, AH Plus and Real Seal groups. Residual material was most often found in the apical third.</p><p><strong>Keywords </strong></p><p>Dental radiography; Endodontic retreatment; Root canal filling materials; Scanning electron microscopy.</p>

The success of endodontic treatment depends on many factors. The most important of them are the knowledge and manual skills of the dentist.Materials and methods. We analyzed the condition of teeth after endodontic treatment in 300 patients aged 20 to 70 years. Were studied 300 images of CBCT, the number of treated teeth and the number of cases of unsuccessful endodontic treatment was analyzed.Results. According to CBCT data, high-quality obturation of the root canal system was observed in 1335 (75%) endodontically treated teeth. The reasons for successful endodontic treatment are under-sealing of the root canal (16%), removal of material beyond the apex (5.6%), and missed root canals (3.4%).Conclusion. Clinical dental patient examination revealed that maxillary and mandibular molars most often undergo endodontic treatment.

ABSTRACTObjective: This study aimed to evaluate the relationship between the quality of the coronal restoration and the root canal filling on the periapical status of endodontically treated teeth using CBCT. Materials and Methods: CBCT data were obtained from the records of patients who deny any dental treatment in the 2 years prior to the CBCT examination. CBCT images (90 kVp and 7 mA, exposure time of 23 s, and a voxel size of 0.2 mm, with a field of view of 13 cm x 13 cm) of 1011 endodontically treated teeth were observed. A score was given to the quality of the root filling and the quality of the coronal restoration. Statistical Analysis Used: Data were statistically analyzed to correlate the periapical status with gender, dental group. and quality of endodontic treatment and restoration (Chi-square test with a significance level of P < 0.001). Results: Absence of periapical periodontitis was found in 54.9% of the cases. The periapical outcome was not related to gender or dental group (P > 0.05). A statistically significant factor (Chi-square test, P < 0.0001) resulted when different qualities of sealing were compared. Conclusions: CBCT showed that high-quality root canal treatments followed by an adequate coronal sealing restoration avoid the presence of periapical periodontitis in time.
