ABSTRACT Cleaning and shaping of root canal system forms the most important step in root canal root canal therapy. Unfortunately most of the instruments and techniques advocated are unable to remove residual debris and bacteria, ultimately resulting in pain and failure. To eliminate the causes of pain, and ensure success, we must use instruments and employ a technique that can best accomplish proper cleaning and shaping. Virtually all canals have parallel walls, and are curved and oval in shape. Hence tapered instruments are unable to clean the canal effectively and increase the chances of ledges and transportation and extrusion of debris beyond the apex. With the introduction of Light Speed technology primary goal of endodontics which includes removal of debris safely and effectively can be achieved. This article focuses on the use of Light Speed technology to overcome the difficulties posed by the other instrumentation and techniques to achieve debris and bacteria free canal system.

Apical periodontitis is an inflammation of dental periapical tissues developed as a response to colonization of microorganisms in root canal system. Etiology of periapical pathology is associated with different species of microorganisms that are not fully defined yet. The changes in the composition of root canal microbiota as well as other factors, such as host resistance to various infections and concomitant viral infection, etc., can influence development of the symptomatic apical periodontitis. Etiology of disease is reviewed in this article. The purpose of treatment of symptomatic apical periodontitis is to eliminate the infection in root canal system and to obtain relief of symptoms. It can be done by conventional root canal therapy, which can be combined with anti-inflammatory medication. Indications for antibiotic therapy in such cases are limited to particular occasions, which are considered in article. Nevertheless, findings show that usually dentists prescribe antibiotics improperly in clinical practice. It can render drugs ineffective against diseases of dental origin as well as against potentially fatal infectious diseases. Selection of antibiotics for the treatment of root canal infections is reviewed in this article. Importance of antimicrobial susceptibility testing is emphasized. There is a need for more research on microbial causes and interactions in different forms of apical periodontitis to improve diagnosis and treatment.

Necrotic Debris

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.

Micro Organisms

The presence of micro-organisms within the root canal system is the critical aetiological factor in peri-radicular periodontitis. During root canal treatment (RCT) it is imperative that this infection and other organic debris are removed from the root canal system. This is challenging because complex tooth anatomy, the presence of a biofilm and the smear layer complicate the process. There are a number of irrigant chemicals and adjunctive systems available in contemporary endodontic practice that are used to disinfect the root canal system during root canal preparation. This article reviews the available evidence concerning these disinfection methods and concludes by presenting a clinical protocol supported by the literature. CPD/Clinical Relevance: A clinical protocol, supported by the literature, is presented for effective decontamination of the root canal system during root canal therapy.

The study determined the antiseptic activity of modern drugs in the form of liquids presented on the territory of the Russian Federation, drugs were used for long-term antiseptic treatment of the root canal system of teeth. The need to use these drugs is justified by the microbial insemination of the root channels and the presence of various branches at all levels of the root channel. Thus, the obtained results make it possible to state that the degree of antiseptic activity of the preparations depends on the exposure time. The study established the strong antiseptic effect of the drug Kresotin No. 2. As follows from the analysis of the above materials, the antiseptic activity of Pulpevit No. 2, Gwayafen forte, Camforfen showed minimal results with respect to the microflora of the experimental part of the study.

ABSTRACT The complex anatomy of the root canal system takes up many configurations and variations are not uncommon. A clinician should be aware of the normal, so as to recognize these aberrations in the anatomy. Successful root canal therapy is achieved by thorough shaping and cleaning of the root canal system followed by obturation of the radicular space. The aim of the present article is to describe a case of a mandibular second molar with an unusual anatomy of having a single mesial canal and two distal canals which is in reverse to usually seen, encountered during routine endodontic treatment. The clinician should always keep in mind that anatomic aberrations can occur in any tooth and the recognition of these is achieved by thorough examination of the internal anatomy of the tooth and its radiographs.

Evaluating morphology of a root canal is important in determination of a successful endodontic therapy. This article highlights the need to be aware of different morphologies, which can exist in the root canal system of upper molars. This is usually associated with buccal root and has been documented in several studies in literature. On the other hand, it is not often that we come across variations in the palatal roots. These cases discuss such a case where two canals were discovered in palatal root during root canal treatment of maxillary first molar. It is essential to evaluate pre-operative radiographs and have proper knowledge of anatomy of the root canal system before initiating the treatment. All roots must be explored carefully to ensure that all canals are negotiated, debrided and obturated to ensure successful endodontic outcome. This case report shows a case series in endodontic management of a maxillary first molar with two palatal canals.

Brief Background: The main requisites for an endodontic treatment to succeed are adequate cleaning and shaping of the root canals. Several conventional root canal irrigants are in use to decrease the number of microbes in the root canal system. Enterococci are the most frequently isolated organisms in failed root canals. Aim: To compare the anti-bacterial efficacy of herbal root canal irrigating solutions with conventional irrigants. Materials and Methods: The test solutions and tooth samples were prepared. The sectioned tooth samples were inoculated in the bacteria, incubated for 24 hours and biofilm collected. Another sample of biofilm was collected after delivering of the irrigating solutions. Bothe the biofilm samples were checked for the reduction in the bacterial growth. Results: The present study was conducted to evaluate the anti-microbial efficacy of herbal irrigating solutions and compare them with the conventional irrigating solutions. Chlorhexidine (CHX), Ocimum sanctum (OS) and Sodium hypochlorite (NaOCl) showed no statistical significance whereas the other intergroup differences were statistically significant. Summary and Conclusion: OS showed a similar anti-bacterial efficacy to CHX and NaOCl, however, further research needs to be conducted in the area. The use of herbal alternatives may prove to be advantageous given the several unfavourable adverse effects of NaOCl and CHX. Key Words: Antibacterial, Chlorhexidine, Herbal irrigants, Ocimum, Root canal irrigants.
