Root Canal System

Videofluoroscopy was used as a radiographic technique to visualize a canine tooth during root canal therapy in a Siberian tiger. Videofluoroscopy was useful because the procedure was performed in a zoo setting with no access to an on-site darkroom. The fluoroscopic screen and videotape allowed for immediate viewing of the root 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.

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.

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.

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.

Abstract Persistent apical periodontitis (AP) is a situation involving an inflammatory and immune response caused mainly by anaerobic polymicrobial infection of the root canal system and the outcome and follow-up of the root canal treatment has been reported as intimately related to host response. The apical periodontitis repair might be associated with genetic polymorphisms. This study aimed to evaluate the association between HIF1A genetic polymorphisms (rs2301113 and rs2057482) with PAP in Brazilian patients. Subjects with at least 1 year of follow-up after root canal therapy (RCT) were recalled. Sixty-four subjects with signs/symptoms of PAP and 84 subjects with root canal-treated teeth exhibiting healthy perirradicular tissues (healed) were included. Genomic DNA was extracted from saliva and used for HIF1A genotyping by real-time PCR. Genotype and allele frequencies were compared by c2 or Fisher’s exact tests and odds ratio was implemented, using Epi Info 3.5.2. All tests were performed with an established alpha of 0.05. There was no association between allele and genotype distribution for HIF1As polymorphisms and PAP (p>0.05). The genetic polymorphisms in HIF1A were not associated with persistent apical periodontitis.

AbstractThis study aimed to analyze the root anatomy and root canal system morphology of mandibular first premolars in a Chilean population. 186 teeth were scanned using micro-computed tomography and reconstructed three-dimensionally. The root canal system morphology was classified using both Vertucci’s and Ahmed’s criteria. The radicular grooves were categorized using the ASUDAS system, and the presence of Tomes’ anomalous root was associated with Ahmed’s score. A single root canal was identified in 65.05% of teeth, being configuration type I according to Vertucci’s criteria and code 1MP1 according to Ahmed’s criteria. Radicular grooves were observed in 39.25% of teeth. The ASUDAS scores for radicular grooves were 60.75%, 13.98%, 12.36%, 10.22%, 2.15%, and 0.54%, from grade 0 to grade 5, respectively. The presence of Tomes’ anomalous root was identified only in teeth with multiple root canals, and it was more frequently associated with code 1MP1–2 of Ahmed’s criteria. The root canal system morphology of mandibular first premolars showed a wide range of anatomical variations in the Chilean population. Teeth with multiple root canals had a higher incidence of radicular grooves, which were closely related to more complex internal anatomy. Only teeth with multiple root canals presented Tomes’ anomalous root.

We aimed to analyze the morpho-geometric changes of the root canal system created by two rotary systems (TF Adaptive and BioRace) using micro-CT technology. Two concepts of rotary file system kinematics, continuous rotation and adaptive kinematics, were used in root canal preparation. Twenty mandibular molars (n = 20) were selected with the following criteria: the teeth have mesial roots with a single and continuous isthmus connecting the mesiobuccal and mesiolingual canals (Vertucci’s Type I configuration) and distal roots with independent canals. Teeth were scanned at a resolution of 14 μm. Canals were divided equally into two groups and then enlarged sequentially using the BioRace system and TF Adaptive system according to manufacturer protocol. Co-registered images, before and after preparation, were evaluated for morphometric measurements of canal surface area, volume, structure model index, thickness, straightening, and un-instrumented surface area. Before and after preparation, data were statistically analyzed using a paired sample t-test. After preparation, data were analyzed using an unpaired sample test. The preparation by both systems significantly changed canal surface area, volume, structure model index, and thickness in both systems. There were no significant differences between instrument types with respect to these parameters (p > 0.05). TF Adaptive was associated with less straightening (8% compared with 17% for BioRace in the mesial canal, p > 0.05). Both instrumentation systems produced canal preparations with adequate geometrical changes. BioRace straightened the mesial canals more than TF Adaptive.
