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.

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.

The purpose of this study is to evaluate the morphological characteristics of the roots and roots canals of primary molar teeth using Cone-Beam Computed Tomography (CBCT).<br/>A total of 68 CBCT images of children aged 4 - 5 years was used for this study. A total of 160 molar teeth were analyzed. Various parameters such as the number of roots and canals, length of root and root canal, and the angulation and shape of the roots were analyzed.<br/>All maxillary primary molars had 3 roots. The presence of 2 root canals in 1 root was only observed in the mesiobuccal root of maxillary primary second molars. Most mandibular primary molars had 2 roots, and most mesial roots had 2 root canals.<br/>Concerning the length of the roots, the palatal root of the maxillary primary molar was found to be longest whereas the distobuccal root was shortest. In mandibular primary molars, the mesial root was longer than the distal root. In maxillary primary molars, the palatal root had the greatest angulation whereas the distal root has the greatest in mandibular molars. The root and root canals of maxillary primary molars were more curved in shape whereas mandibular primary molars were straight.

AIM: To analyse the root canal morphology of mandibular third molars using clearing technique. MATERIAL AND METHODS: Ninety permanent extracted mandibular third molar teeth were collected based on inclusion and exclusion criteria. Teeth were then decalcified and were made transparent Methylene Blue Dye was injected to color the pulp space. These teeth were then observed under sterio Microscope and root canal systems were identified according to Vertucci's Classification. RESULTS: The most common anatomical morphology found was having two roots. Overall type I Vertucci’s configuration was the most common pattern of canals. Other canal patterns that were found included type II, III, IV and V. In this study no canal of type VI, VII or VIII were found. CONCLUSION: The morphological variations in root patterns and canal configuration of mandibular third molar should be given consideration for successful 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.

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.

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.

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.
