Knowledge regarding the morphology of the endodontic system is crucial when performing both a treatment and a retreatment which should be both efficient and predictable. The misapprehension regarding the anatomy of the root canals is one of the various issues which might occur during the endodontic treatment, as well as afterwards. The aim of this article is to emphasize, through a clinical case, the failure of a primary endodontic treatment, due to the misapprehension regarding the internal morphology of the inferior incisors, which in turn led to errors in preparing the cavity for endodontic access, to neglect the instrumentation, the lavage and the obturation of the second canal, and finally determining the occurrence of a manifest apical lesion. In order to achieve a good final result, the two canals underwent correct retreatment and tight obturation, after which the patient will be radiologically and/or computertomographical monitored for at least two years.

Background: The internal anatomy is a complex system and root canal morphology varies between teeth, especially in maxillary second premolars. Objective: The purpose of this present study is to identify the variations in root and root canal morphology of the upper second premolar. Methods: A retrospective study on 197 maxillary second premolars, which have had an endodontic treatment in Ajman University in the Academic Year 2018/2019. Intraoral periapical (IOPA) radiograph was reviewed for identifying the number of root canals. Results: The incidence of two canals in the maxillary second premolars was very high 78.7%, and the internal anatomy is complex and highly variable. Conclusion: A straightforward message to the clinicians to be careful in their evaluation and to take care whenever an upper maxillary second premolar is to be treated endodontically.

ABSTRACT Successful root canal treatment depends on having comprehensive information regarding the root(s)/canal(s) anatomy. Dentists may have some complication in treatment of third molars because the difficulty in their access, their aberrant occlusal anatomy and different patterns of eruption. The aim of this review was to review and address the number of roots and root canals in third molars, prevalence of confluent canals in third molars, C-shaped canals, dilaceration and fusion in third molars, autotransplantation of third molars and endodontic treatment strategies for third molars.

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.

A thorough knowledge and understanding of the root canal morphology including the variations is important for the successful outcome of endodontic treatment. The success of an endodontic treatment depends on the eradication of microbes from the root-canal system and prevention of re-infection [1] . The variations in mandibular first molar involves the number of roots, the number of root canals, and morphology. Radix entomolaris and the radix paramolaris are the additional root located lingually and buccally respectively [2] . This case report discusses endodontic treatment of a mandibular first molar with a radix entomolaris and pulp stone.

ABSTRACT Aim This clinical report presents a rare case of maxillary central incisor with two separate roots. Background Unusual morphology of the roots and root canals may exist in any tooth. Recognition of the dental anatomy and its variations is necessary for successful endodontic therapy. It is well known that maxillary incisors are usually single-rooted teeth. Case report The root canals were instrumented with conventional hand files and Gates Glidden and obturated by using the lateral technique. Recall radiograph after 1 year shows the healing process of the preoperative apical periodontitis. Conclusion and clinical significance Clinicians should be aware of unexpected root canal morphology when performing root canal therapy. The present case demonstrated the importance of accurate preoperative radiograph and adequate access preparation. How to cite this article Maghsoudlou A, Jafarzadeh H, Forghani M.

It is of interest to compile available information on the root canal morphology of primary maxillary molars from known literature. The literature resources used to collect data include Medline/PubMed, The Cochrane Central Register of Clinical Trials, SIGLE and Science Direct. Data consists of type of population, number of teeth per study, number of root canals, canal length and type of root canal configuration. We used data from a total of 13 studies (951 primary maxillary molars). Maxillary molars (1st and 2nd) are dominant for two roots variant. The first molar the mean root length ranges from 7.9mm – 8.1mm. The second molar ranges from 7.2mm-8.5mm. Type I (explain in a phrase) canal morphology is the common variant in both the molars. Data shows that Root Canal morphology shows variations with the diagnostic aid (example micro CT) used and in different ethnic populations.

Root Canal Morphology

Introduction. Predictable endodontic treatment depends on the dentist?s knowledge about root canal morphology and its possible anatomic variations. The majority of mandibular canines have one root and root canal, but 15% may have two canals and a smaller number may have two distinct roots. The following clinical reports describe endodontic treatment of mandibular canines with two roots and two root canals. Outline of Cases. Four clinical case reports are presented to exemplify anatomical variation in the human mandibular canine. Detailed analysis of the preoperative radiographs and careful examination of the pulp chamber floor detected the presence of two root canal orifices in all canines. Working length was determined with an electronic apex locator and biomechanical preparation was carried out by using engine driven BioRaCe Ni-Ti rotary instruments in a crown-down manner, followed by copious irrigation with 1% sodium hypochlorite. Definitive obturation was performed using cold lateral condensation with gutta-percha cones and Top Seal paste. The treatment outcome was evaluated using postoperative radiographs. Conclusion. Endodontists should be aware of anatomical variations of the treated teeth, and should never presume that canal systems are simple.

Canal Morphology

The complex root canal system of maxillary second premolars shows variations among different populations. The aim of this study was to evaluate the root canal morphology of second maxillary premolars in the romanian population. The number of roots, root canals and the root canal configuration were investigated using radiographs in both buccal-oral and mesio-distal incidence. They were categorized using Weine’s classifi cation. Among the 480 teeth, 90.83% had one root and 66.67% one root canal. The frequency of secondary maxillary premolars with two root canals (33.12%) shouldn’t be underestimated. Knowing the variations of the internal root canal morphology of maxillary second premolars in a certain population can lead the clinician to a better approach of the endodontic treatment.

Canal Morphology

A comprehensive knowledge of the root canal morphology and its variations is a basic requisite for the success of the endodontic treatment. Mandibular molars may present a third or additional root, which if located lingually is called radix entomolaris or bucally is referred as radix paramolaris. This case report shows an endodontic retreatment of a radix entomolaris and details some variations in the approach to guarantee a successful terapy.
