Endodontics remains a rapidly advancing branch of restorative dentistry. It is highly likely that, by the time this book is published, several new or updated endodontic file systems will have been released. Despite the fairly rapid technological advances that the profession has seen, the key principles of endodontic treatment remain the same: 1. Eliminate microorganisms from the root canal system 2. Prevent reinfection of the root canal system 3. Retain a functional natural tooth. Whilst these principles are easy to discuss, they are consistently diffi­cult to perform, due, in large part, to the complexity of the root canal system. Multiple theories, principles, and approaches have been discussed to help achieve an optimal technical and clinical outcome. However, evi­dence to favour one specific stage or system over another is lacking, and as such, a large degree of operator preference and experience will ultimately influence the treatment planning and technical strategy. Much like baking a cake, endodontic treatment relies upon a series of proced­ural steps to achieve a desirable outcome, which, for the patient, often equates to a functional, pain-free natural tooth. Good- quality magnification remains a key component of an endodontist’s armamentarium, and dental loupes or a dental operating microscope could not be recommended more highly. Key topics include: ● Endodontic case assessment, including root canal anatomy ● Pain management, including local anaesthesia ● Access and canal identification ● Vital pulp therapy, including caries management ● Canal negotiation and instrumentation ● Root canal irrigation ● Root canal obturation ● Restoration of the endodontically treated tooth.

Root Canal System

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.

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.

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.

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.

Introduction The main purpose of endodontic treatment is to clean the root canal system, eliminate the infected and toxic contents, and shape it in order to get a tridimensional obturation. The aim of this paper is to inform dental practitioners about crown-down techniques for root canal preparation using nickel-titanium rotary instruments. Root canal preparation Today most endodontists believe that root canal preparation is more officious, cleaning and shaping are better, if pre-enlargement of coronal two thirds is performed first, and shaping of the apical part later. Machine driven rotary instruments provide much quicker and better root canal preparation. Conclusion Contemporary endodontic rotary files vary in regard to their taper, cutting blades, guiding tip and material they are made of. The usage of rotary nickel-titanium files adds a new quality to root canal preparation.

The most important requirements for successful endodontic treatment are accurate diagnosis and good knowledge of canal morphology. A mandibular second premolars rarely have more than one root and one root canal. Data from the literature indicate low percentage of a mandibular premolars with three or more root canals. Unusual morphology of the root canal system is diagnostic and therapeutic challenge. It is very important to analyze preoperative radiograph and to explore thoroughly the entrance of the root canal. The aim of this study was to present two patients who had lower second premolars with three canals that required endodontic therapy.

Root Canal System

The ultimate goal of an endodontic treatment is to achieve the fluid tight seal particularly at the apex as well as in coronal aspect of the root canal system. This is mainly influenced by the cleaning and shaping of root canal system and it has been recognized as an important phase of endodontic therapy. Cleaning and shaping as well as obturation are best accomplished when the file taper claimed by the manufacturer is accurate and the taper of the canal following instrumentation corresponds to the taper of the file. Despite the most advanced technology in manufacturing of dental instruments, variations in endodontic file tapers still exist. Therefore the purpose of this study is to compare the taper variation in root canal preparations among the three different NiTi files using CBCT. Methods: 24 upper 1st molar tooth with mesiobuccal root curvature 15-30 degree were selected and divided into three groups. Mesiobuccal roots (MB1) of three groups were prepared by three different NiTi file system respectively up to size25 taper.06 and CBCT were done separately for each group. The diameter was measured at 1, 3, and orifice in mm and canal taper preparation was calculated using CBCT. Result: Of the 3 file systems, fell within the ±.05 taper variability. All preparations demonstrated variability when compared to the nominal taper .06. Conclusion: Taper preparations of the investigated size 25 taper .06 were favorable but different from the nominal taper.
