The outcome of endodontic treatment directly depends on the high-quality instrumental and medical treatment of root canals. The most effective, widespread and well-known antiseptic used for rinsing root canals is sodium hypochlorite. Unfortunately, in the process of irrigation complications arise in the form of sodium hypochlorite of various concentrations extrusion into the periapical region. We must not forget about the anatomical and topographic features of the structure of nearby structures, such as the mandibular canal and the maxillary sinus. The aim of the clinical case is to assess the depth of irrigant penetration into the periodontal area using radiography and to develop an algorithm for actions in the event of a hypochlorite accident.

Root Canal System

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.

Effective shaping and cleaning of root canals are essential for the success of endodontic treatment. Due to the complex anatomy of root canal spaces, the use of various instrumentation techniques alone is not effective in producing bacteria-free root canal spaces. Irrigation, disinfectants, rinses, and intervisit medications are used in conjunction with the mechanical instrumentation to ensure the success of endodontic treatment. Sodium hypochlorite (NaOCl), a halogenated compound, is routinely used to irrigate the root canal during endodontic treatments. NaOCl has been known for its antibacterial action, proteolytic and dissolution capacity, and debridement properties. NaOCl, however, can alter the composition of dentin and hence its interaction with the adhesive resins used to bond the restorative materials to treated dentin. This review therefore covers in depth the action of NaOCl on dentin-adhesive resin bond strength including both enhancement and reduction, then mechanisms proposed for such action, and finally how the adverse action of NaOCl on dentin can be reversed.

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.

Success in root canal treatment is achieved after thorough cleaning, shaping, and obturation of the root canal system. This clinical case describes conventional root canal treatment of an unusual mandibular first molar with six root canals. The prognosis for endodontic treatment in teeth with abnormal morphology is unfavorable if the clinician fails to recognize extra root canals.

Background: Complete obturation of the root canal with an inert filling material and creation of a fluid-tight seal are among the major goals of successful endodontic treatment. Methods: Extracted mandibular premolar teeth were decoronated, prepared in a crown-down fashion and irrigated with 2.5% sodium hypochlorite and 17% EDTA. The specimens were randomly assigned into 4groups (n=10/each) and obturated with gutta-percha and Resilon/Epiphanywith different sealers. Horizontal sections were obtained of the coronal, middle and apical third at levels of 14-mm, 8-mm and 2-mm from the apex respectively and were viewed under magnification. The area of obturating material, sealer and voids were calculated using Image Jsoftware. Statistical comparisons between the Resilon and gutta-percha groups were made with Kruskal-Wallis Test and intergroup comparisions were made by Mann-Whitney U test with Bonferroni correction. Results: The results of this study showed that root canals obturated with gutta-percha or Resilon with Epiphany as sealer had significantly less area of sealer plus voids and voids alone as compared to root canals obturated with gutta-percha and AH Plus as sealer or gutta-percha and GuttaFlow. Conclusion: From the results of this study it can be concluded that methacrylate resin-based sealer Epiphany will lead to a better obturation of the root canals and adhesive sealers hold a better prospective.

Objectives. The aim of this study was to determine whether irrigation with sodium hypochlorite, chlorhexidine, and ozone gas, alone or in combination, were effective againstEnterococcus faecalisandCandida albicans; these are microorganisms frequently isolated from teeth with periapical lesions resistant to endodontic treatment.Material and Methods. 220 single root teeth, recently extracted, were inoculated withCandida albicansandEnterococcus faecalis. The formulations tested were sodium hypochlorite at 1, 3, and 5% chlorhexidine at 0.2% and 2% and ozone gas applied for different periods of time. The combination of sodium hypochlorite at 5% and chlorhexidine at 2%, with gaseous ozone, were also assessed. For the most active treatments the mechanism of action was assessed through flow cytometry.Results. Sodium hypochlorite, chlorhexidine, and gaseous ozone alone were ineffective in completely eliminating the microorganisms. The association of chlorhexidine at 2% followed by ozone gas for 24 seconds promoted the complete elimination ofCandida albicansandEnterococcus faecalis. Flow cytometry shows that ozone and chlorhexidine act differently, which could explain its synergic activity.Conclusions. This new disinfection protocol, combining irrigation with chlorhexidine at 2% and ozone gas for 24 seconds, may be advantageous when treating infected root canals.

In recent years, our country has seen positive trends in improving the effectiveness of endodontic dental treatment due to the introduction of modern technologies that allow predicting the results of dental treatment. However, in clinical practice, the number of unsuccessful treatment outcomes for caries complications has not decreased. It is known that the key to the effectiveness of endodontic treatment is the "three whales": cleaning, sterilization and obturation of the root canal system. However, at each stage of endodontic treatment, a significant number of errors are obtained. Thus, according to x-ray examination, it was found that only in 13.4% of cases the root canals were filled satisfactorily. But even with high-quality obturation, in 5-8% of cases, there is inflammation in the periodontium.

Endodontic lesions take leading positions in the structure of modern dentistry. General areas of the displacement of filling material or instruments because of the poor quality of endodontic treatment have been established, and the features of clinicoroentgenological and neurological manifestations of the complications of endodontic dentistry have also been determined. Due to the poor quality of endodontic treatment, general areas of the displacement of filling material or instruments have been identified, they are the mandibular canal, the maxillary sinus and periapical bone tissue. We have performed the examination of 32 patients with various complications after endodontic treatment during 2017 to 2018. The majority of patients were adults – 28(87,5%), over the age of 60 – 4(12,5%), there were 84,4% females and 15,6% males within the group. The patients were divided into 3 groups according to localization of foreign bodies: the first group contained patients with foreign bodies present in the area of mandibular canal – 5(15,6%); the patients represented by the material in the maxillary sinus cavity made up the second group – 9(28,1%); the group of patients whose material was localized behind the tooth apex in the bone tissue included 18(56,2%)persons. The greatest number of complications after endodontic therapy was observed during the treatment of molars– 67,9%. Duration of disease (from the end of endodontic treatment to the hour of addressing the clinic) varied from 1 to 6 months. For the purpose of identification, the foreign material localization along with traditional clinic examination, which includes complaints analysis, anamnesis data, estimation of general health status and local manifestations of the disease, the dental intraoral X-ray, plain roentgenography and computed tomography of the bones of the jaws were performed. Assessment of the tissues sensitivity was conducted by the method of comparative palpation of the skin and mucosa at the areas of innervation of the trigeminal nerve branches. As a result of the investigation we have determined that regardless of exact localization of the foreign material, surgical complications after endodontic treatment were always accompanied with pain syndrome of different intensity, reduction of sensitivity during the placement of the filling material in the area of mandibular canal (extra- or intracanal), signs of inflammation development (bounded or generalized adjacently to mucosa of maxillary sinus) or persistent pain syndrome during displacement of filling material into the bone tissue behind the tooth apex. To specify areas and borders of the localization of the foreign body, the findings of the roentgenological investigations, in particular computed tomography, were critical.

Successful and predictable endodontic treatment requires knowledge of root canal anatomy and morphology variations. In cases where X-ray images do not help to clarify the anatomy of the root canals, it is recommended to use magnifying devices. The second premolar of the lower jaw is one of the most diffcult teeth for endodontic treatment due to variations in internal morphology, additional root canals, apical deltas, and lateral canals. Diagnostic radiographs in different projections are important for getting an idea of the number of existing root canals. The purpose of root canal treatment is to clean the root canal of pathogenic microbes and infected pulp, prevent the formation of toxic products, and protect the periapical tissue. The presence of root canal variability increases the complexity of endodontic treatment. The complex anatomy of the root canals, the presence of additional channels, unnoticed by the dentist, can cause the failure of endodontic treatment.
