Plenty variants of the teeth endodontic structure requires a thorough study of the root canal anatomy and morphology peculiarities, which will make it possible to estimate the volume and complexity of future endodontic intervention, make a prediction of the treatment result, and forecast possible complications. For an objective assessment of the tooth root system anatomical and morphological features, the main method is x-ray examination. Endodontic treatment planning requires the doctor to estimate his capabilities (in difficult cases, it is necessary to refer the patient to a specialized clinic), calculate future working time (it takes more time to treat a tooth with complex anatomy), and to have all the necessary set of endodontic instruments. If endodontic treatment is impossible, then it’s necessary to consult with a dental surgeon to select a combined approach for treatment (root apex resection, root amputation, tooth hemisection). Purpose of the study. To analyze different variants of roots and root canals anatomical structure of the lower jaw teeth according to literature sources and by X-ray pictures of the authors’ own observations. Materials and research methods. Variants of the anatomical and morphological features of the lower jaw teeth’ roots and root canals structure were analyzed according to literature sources and 405 x-rays of our own observations. The results of the study. The information presented in this article allows to deepen the clinician knowledge concerning the tooth cavity size and shape, the roots and root canals anatomy, the presence of additional channels, as well as the degree of the root canal curvature, and to choose the right channel instrumentation technique and the necessary tools. Often, the proper full working length root canal treatment depends on the degree of curvature and its location. The X-ray analysis of anatomical and morphological features of the lower jaw teeth’ roots and root canals, enables us to identify both common and individual features of a tooth anatomy. When analyzing radiographs of the lower jaw teeth, it is necessary to take into account the projection of the tooth cavity on the outer surface of the crown, as well as signs that may change due to age, caries, non-carious lesions, restorations, and trauma; also anomalies of the position of the tooth in the arch, individual anatomy of the roots, the number of roots and type of root canals, the shape of their cross section (from the orifice to the apex), the direction and length of the roots, the angle of curvature, the number of bends, their localization. For the right choice of the root canal treatment technique and the necessary tools, it is important for the clinician to know the degree of bending of the root canal. Each case requires an individual and skilled approach. Therefore, to assess the possible structural features of the tooth root system, it’s efficiently to use the most modern tools, equipment, and X-ray tactics. The literature data and the analysis of our own radiographs allow us to solve successfully and predictably difficult clinical problems of both primary treatment and retreatment endodontic cases.

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.

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.

ABSTRACT Introduction A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing occurring after endodontic therapy in patients with C-shaped root canals in mandibular molars. Materials and methods The present study was conducted in the Department of Conservative Dentistry of the institution and included assessment of all the patients who underwent root canal treatment of the mandibular first and second molars. Endodontic therapy was performed in all the cases by experienced endodontist. Final postoperative radiographs were taken. Recording of the data of the personal and clinical details of a total of 250 patients was done. All the clinical and radiographic details of the patients, such as tooth location in the jaw, presence or absence of C-shaped canals, status of the pulp tissue, presence or absence of the fractures, and other details of the patients were recorded. Radiographic and clinical examination of the tooth of the patients was done during the baseline visit and further during the follow-up visits. The presence of C-shaped root canals was confirmed using the radiographs. Periapical index (PI) scoring system was used. Categories defined for enlisting the healing after the root canal treatment with the assessment of the PI score. All the results were analyzed by Statistical Package for the Social Sciences software. Results Vital pulp tissue was encountered in majority of the cases. C-shaped root canal configuration was observed in 40% of the cases included in the present study. After completion of the endodontic therapy, complete crown placement was done in only 22% of the cases. In cases of vital teeth with C-shaped root canals configuration, most of the teeth showed complete healing. Significant results were obtained while comparing the complete coverage crown parameter in relation to the healing process in teeth with C-shaped root canals. Conclusion In the present study, no significant effect of the C-shaped root canal configuration was found on the healing rate of the endodontic therapy in mandibular molars. Clinical significance Meticulous endodontic therapy with special techniques should be done while preparing teeth with C-shaped root canals.

Root Canal System

Successful outcome of endodontic treatment depends on the identification of all root canals which in turn guarantee complete extirpation of pulp tissue, proper chemo-mechanical cleaning and shaping and three dimensional obturation of the root canal system with an inert filling material. However endodontic treatment can fail for many reasons, such as diagnostic errors, persistence of the infection in the root canal system, errors in debridement and shaping of the root canal systems, instrument fractures, poor restorations and extra roots or canals if not detected are the reasons for failure. Undetected extra roots or root canals have been considered as a major reason for failure of root canal treatment. Many of the challenges faced during root canal treatment may be directly attributed to an inadequate understanding of the canal morphology of teeth. A broad knowledge of both the external and internal anatomy of teeth is of great importance for adequate endodontic treatment. We present a case report of 2 roots in mandibular lateral incisor.

The use of nickel-titanium instruments have become an important part of the root canal treatment, in order to facilitate the cleaning and shaping of root canals, because the incorrect utilization of the endodontic files during endodontic treatment may produce unwanted procedural errors. The aim of this study was to evaluate on simulated curved root canal models the cleaning efficiency and the apical transportation in three reference areas of the root canal files, ProTaper (Dentsply Maillefer), K3XF (Sybron Endo) and HyFlex (Coltene Endo) systems, compared to the hand K-files (DentsplyMaillefer). According to our results, rotary file systems are more efficient than the hand files, in cleaning the root canal.

Objectives. The aim of this study was to investigate the number of roots and root canals in the maxillary second premolar in a group of Jordanian population.Materials and Methods. A total of 217 patients, 100 female (46%) and 117 male (54%), received root canal treatment of maxillary second premolar from January 2012 to January 2014. The mean age of the patients was 32.7, ranging from 18 to 60 years. The teeth included in the study were examined clinically and radiographically for the number of roots and root canals using magnifying loupes.Results. Out of the total of 217 maxillary second premolars, 120 teeth had one root (55.3%), 96 teeth had two roots (44.2%), and one tooth had three roots (0.46%). Regarding root canal configuration, 30 teeth (13.8%) had one canal, 54 teeth (24.9%) had two canals shared in one apical foramen, 132 teeth (60.8%) had two canals with two separate apical foramina, and one tooth (0.46%) had three canals with separate apical foramina.Conclusion. The incidence of two canals (either with shared or separate apical foramina) is very high in the maxillary second premolars in Jordanian population; therefore inspection should be done for the presence of second canal whenever endodontic treatment is planned for this tooth.

Mandibular First Molar

Undetected extra roots or root canals are a major reason for failure of endodontic treatment. Failure to recognize an extra distolingual (DL) root in mandibular first molar may lead to incomplete debridement of the root canal system and eventually treatment failure. Therefore, it is crucial that atypical anatomy is identified before and during dental treatment. Spiral computed tomography (SCT) images can show 3D images, and therefore much detail can be used when traditional methods prevent adequate endodontic treatment. The overall incidence of DL roots on the mandibular first molars was 6.40% for all patients and 5.00% for all teeth, respectively. The occurrence of DL roots on the right side and on the left side showed a statistically significant difference. The bilateral incidence of symmetrical distribution of DL roots was 56.25%. The DL root canal orifice was separated from DB canal orifice by2.79±0.34 mm, from the MB canal orifice by4.23±0.81 mm, and from the ML canal orifice by3.29±0.52 mm. The high prevalence of the DL root in permanent mandibular first molars among the Indian population by using SCT and estimations of the interorifice distance of such teeth might be useful for successful endodontic treatments.

Endodontic treatment of the teeth with severe root canal curvatures has become one of the greatest problems in clinical practice. Recently, new instruments and techniques have been introduced in the endodontic procedure. The aim of this study was, on the basis of clinical practice, to show the possibilities of the endodontic treatment in the teeth with severely curved root canals, after dependable decision about endodontic instruments and techniques. This article presents a complete endodontic procedure in two teeth with different curvature shape of the root canal in patients that were treated at the Department of Restorative Dentistry and Endodontics, School of Dentistry, Belgrade. Coronal to apical 'crown down' technique was used for the root canal preparation with hand NiTi ProTaper instruments with progressive multicone design. The main reasons for choosing manual technique were complexity, shape of presented curvatures and better tactile sensation control of canal instruments in order to avoid possible mistakes and complications. Clinical X-rays of the teeth with permanent obturation clearly showed that extremes of the root canal morphology could be successfully solved by the right choice of all factors during endodontic procedure.
