The widespread prevalence of pulp and periodontal diseases indicates the need for continuous improvement of the method of endodontic treatment and determines the relevance of the development of new methods of complex therapy. The primary etiologic agents of apical periodontitis are microorganisms and their by-products that have invaded the pulpal space and established multispecies biofilm communities in the root canal system. Biofilms are involved in all stages of root canal infection and can be found on root canal walls, in dentinal tubules, and on extraradicular surfaces. The success of endodontic dental treatment is determined by careful mechanical processing using modern instruments, drug treatment and subsequent three-dimensional hermetic obturation of the root canal. Only a high-quality and optimal solution to the three problems allows you to achieve high-quality long-term results of treatment. Instrumentation disrupts biofilms which colonize infected soft and hard tissues and provides access for irrigation and exposure to antimicrobial solutions for disinfection of the root canal system. Disinfection is achieved by the use of both antimicrobial agents and the mechanical flushing action of irrigation, with the goal being the disruption, displacement and removal of pulpal remnants, microorganisms, metabolic byproducts, debris and the smear layer created during instrumentation. The multistage, duration and laboriousness of drug treatment of root canals makes it not always effective, which can subsequently cause unsuccessful endodontic treatment. A practicing dentist should be able to rationally and efficiently utilize standard disinfection protocols in the irrigation and medication of root canal spaces.

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.

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.

Compliance with the algorithms of endodontic treatment in most cases ensures the quality of treatment. However, real, long-term and sometimes immediate results that occur in clinical practice are not always successful. In general, the main reason for the unfavorable outcome of dental treatment is an incomplete sanitation of the root canal system. Modern publications by J. F. Siqueira, I. N. Rocas, and D. Ricucci (2019) note that many issues of endodontic treatment are unresolved. It follows that improving the quality of endodontic treatment is still relevant.Aim. To compare two systems of instruments for root canal preparation with different types of rotation.Materials and methods. To identify a tool that will increase the efficiency of root canal preparation, taking into account their anatomy using CBCT, 24 teeth were removed, taken according to orthodontic or pristidintic indications, without previous endodontic treatment. Among them there were 2 incisors, 1 canine, 6 premolars, 15 molars. In total, 60 canals were examined.Results. The shape changes throughout the canal, turning into a round, oval, slit-like, complementing the configuration by the isthmuses between the canals in 13.3% of cases. WaveOne Gold showed a change in cross-sectional shape after preparation, while ProTaper Universal retained a rounded section of 6.67% after preparation of the slit-like channels.Conclusion. Identified priority technique of root canal preparation, allowing to reduce the number of instruments and, as a consequence, the possibility of technological failures in the root canal to reduce machining of the mouth of the channel, retaining dentine playing a major role in the further prosthesis and positive prediction of remote results.

The primary objective of endodontic therapy is to create a biologically acceptable environment within the root canal system that allows for the healing and maintenance of the health of the peri-radicular tissue. Bacteria are one of the main causes of pulp problems, and they have different methods of penetrating and invading the endodontic space such as through carious lesions, traumatic pulp exposures, and fractures. The types of bacteria found range from facultative anaerobes to aerobes, up to the most resistant species able to survive in nutrient-free environments; the bacterial species Enterococcus faecalis belongs to this last group. Enterococcus faecalis is considered one of the main causes of recurring apical periodontal lesions following endodontic treatment, with persistent lesions occurring even after re-treatment. The review presented in this paper was performed in accordance with the PRISMA protocol and covers articles from the related scientific literature that were sourced from PubMed, Scopus, and Google Scholar using the following terms as keywords: “endodontic treatment”, “endodontic bacteria”, “microbial endodontic”, and “endodontic failure”. Only the articles considered most relevant for the purposes of this paper were read in full and taken into consideration for the following review. The results show that Enterococcus faecalis, Actinomycetes, and Propionibacterium propionicum are the species most frequently involved in persistent radicular and extra-radicular infections.

Microbes are prevalent in the root canals of necrotic teeth, and they are the cause of primary and post-treatment apical periodontitis. Bacteria can dwell within the infected root canal system as surface-adherent biofilm structures, which exhibit high resistance to antimicrobial agents. Bioceramic materials, with their biocompatible nature and excellent physico-chemical properties, have been widely used in dental applications, including endodontics. This review focuses on the application of bioceramic technology in endodontic disinfection and the antibiofilm effects of endodontic bioceramic materials. Different bioceramic materials have shown different levels of antibiofilm effects. New supplements have emerged to potentially enhance the antibiofilm properties of bioceramics aiming to achieve the goal of microbial elimination in the root canal system.

The objectives of root canal treatment are to prevent the apical parodontitis, to heal the acute or cronic apical periodontits and to maintain the results, keeping the teeth on the arch in a functional stage. Thus, accuratelly elimination of soft and hard tissues (cleaning and shaping of the root canal system), disinfection and complete, homogeneous and tridimensional filling of the root canal system are very important to successful endodontic treatment. Modern concepts in endodontic treatment rely on technological progress and therefore many cases are successfully fulfilled, but the practitioner may be put in front of procedural erorrs both during and after endodontic treatment. Apical blockage, ledging, zipping, stripping, perforations in the floor of the pulp canal chamber or root canals perforations are the most common errors, but in many clinical situations they can be prevented and even surpassed once happened.

Subject. Pulp tissue diseases are characterized by a wide prevalence, which makes it possible to consider the quality of endodontic dental treatment one of the most urgent problems of modern dentistry. High-quality treatment of complicated forms of caries is the prevention of odontogenic inflammatory processes, which include periodontitis, periostitis, osteomyelitis, abscess and phlegmon. Therefore, new tools and methods of treatment of complicated forms of caries are proposed, aimed at long-term preservation of teeth as a functional unit of the dental system. Objective: to analyze modern laser technologies in the treatment of complicated forms of caries. Materials and methods. The study was based on the search and study of original articles on the endodontic treatment of complicated forms of caries using laser radiation in the databases: Russian state library, eLibrary, PubMed, the Cochrane Library, Google Scholar. The main selection of materials was carried out by keywords. Results. The literature review describes the positive properties of laser radiation, its mechanism of action, the basics of its use in endodontic treatment, and its application in various branches of dentistry. Conclusions. Analyzing the literature data, we can conclude that the use of laser technologies in the treatment of complicated forms of caries is promising. It is possible to achieve high-quality cleaning of the root canal system and the best long-term results. However, the literature does not sufficiently cover the use of Er, Cr:YSGG laser with a wavelength of 2780 nm in the treatment of purulent pulpitis and pulp necrosis. In addition, taking into account the possibility of using lasers at a therapeutic appointment, it is possible to significantly improve the professional level of a dentist, improving the quality of dental care, reducing the number of complications and preventing various dental diseases.

Pulp debridement and disinfection in the pulp cavity is a critical step in achieving a successful root canal therapy. Microorganisms remaining in the root canal system after endodontic treatment are a main cause of root canal failure. The challenges faced in endodontic disinfection include the complex anatomy of the root canal system, the existence of a biofilm within the root canal, and the creation of a problematic smear layer during instrumentation of the canal. Historically, sodium hypochlorite and ethylenediaminetetraacetic acid have been utilized as irrigants and still remain as the most effective disinfectants due to their synergistic abilities to eradicate microorganisms, dissolve necrotic debris, and remove the smear layer and biofilm. This article addresses challenges in endodontic disinfection, objectives of endodontic irrigants, properties of an ideal irrigant, currently used irrigants, and irrigant delivery systems utilized in veterinary dentistry.

The primary cause of a periapical inflammatory lesion is intra-radicular microbial infection. Prevention and elimination of apical periodontitis is achieved through successful endodontic treatment. Endodontic treatment is designed to maintain and restore the health of the periapical tissues and prevent periapical disease. It may be defined as the combination of mechanical instrumentation of the root canal system with bactericidal irrigation and obturation with an inert material. Technically, the goal of instrumentation and irrigation is to debride and entirely remove infected tissue debris from the root canal system and create a uniform conical shape that allows medicament delivery and adequate obturation. Microbiologically, the goal of instrumentation and irrigation is to eliminate micro-organisms, reduce their survival in the root canal system and neutralise any antigenic potential of the microbial components remaining in the canal.

ABSTRACT Aim C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. Background This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. Case report Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology. Clinical significance The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.
