Iranian Endodontic Journal , 2012,
Abstract: : The aim of this study was to report the endodontic management of right maxillary central incisor having two canals with type IV Vertucci canal configuration. Internal morphology of root canals is variable and often complex. Therefore, to achieve a technically satisfactory endodontic outcome, the clinician must have adequate knowledge of the internal canal morphology and its variations in order to debride and obturate the root canal system thoroughly.

Abstract: Introduction: The knowledge of the complex anatomy of maxillary molars and location of extra canals are essential for diagnosis and endodontic treatment success. Objective: The purpose of this study was to report a clinical case showing a varying number of palatal roots in a second maxillary molar with the aid of operating microscope (OM). Case report: A four-rooted maxillary permanent second molar with 2 separated palatal canals undergone endodontic therapy. After endodontic access, examination of the chamber floor using an operating microscope revealed two distinct palatal canals orifices. A radiograph was taken after the working lengths of each canal were estimated by means of an electronic apex locator which clearly identified the four roots with independent four canals. The canals were instrumented with ProTaper rotatory instruments under irrigation with 5% sodium hypochlorite, obturated with Pulp Canal Sealer and continue wave technique. After completion of root canal treatment, the tooth was restored with composite resin. Results: After endodontic access, the presence of two different palatal canals was found in a second maxillary molar, resulting from a variation in the number of palatal roots of this tooth. Conclusion: The high magnification and clear illumination quality provided by the dental operating microscope increase endodontic treatment success of the variations in the internal anatomy of the tooth.

Open Journal of Stomatology (OJST) , 2015, DOI: 10.4236/ojst.2015.54015
Abstract: Maxillary first molar usually exhibits a radicular anatomy of three roots and three or four canals. However, different anatomic variations like extra number of roots and canals are possible. For a successful treatment, clinicians must have well equipment and a thorough knowledge of the external and internal anatomy of teeth and its variation. Using of CBCT may help to locate extra canals by giving a chance to clinicians to see the root canal anatomy in 3-D view. The aim of this study was to present a case report about a diagnosis and treatment in maxillary first molar with three roots and five canals. It is concluded that the diagnosing and the treatment of unusual cases are key factors for successful endodontic treatment of these teeth.

RSBO , 2012,
Abstract: Introduction: The knowledge on the complex anatomy of the maxillary first molar and location of extra canals are essential for diagnosis and endodontic treatment success. Objective: The purpose of this study was to report a clinical case showing a varied number of root canals in maxillary molars with the aid of the operating microscope (OM). Case report: The endodontic retreatment of the right maxillary first molar with unusual anatomical variation was performed, displaying three canals in the mesiobuccal root (MB), a root canal in the distobuccal root (DV) and a root canal in the palatal root (P). To remove the resin core inside pulp chamber with and without the aid of dental operating microscope, a high-speed drill and ultrasonic tip (diamond round) was used, respectively, for the refinement of the pulp chamber walls. The dental operating microscope was used during the access surgery, operating microscope was used during the access surgery, was used during the access surgery, location, negotiation of canals and checking of the completion of all stages of the retreatment. Subsequently, the cleaning, shaping and filling of the root canal system was completed. The presence of three canals in the mesiobuccal root, one in the distobuccal root and one in the palatal root was found. Conclusion: Variations in the number of canals could be confirmed during the surgery access in endodontic retreatment cases with the aid of dental operating microscope.

Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2010,
Abstract: Unusual root canal morphology in multirooted teeth is a constant challenge for diagnosis and successful endodontic treatment. Presence of extra canals, lateral canals, deltas is commonly encountered but the possibility of existence of fewer number of roots and canals also exists. This clinical report presents a maxillary first molar with an unusual morphology of single root with single canal. This report also highlights the role of spiral computerized tomography as a method to confirm the three-dimensional anatomy of teeth.

Case Reports in Dentistry , 2013, DOI: 10.1155/2013/406923
Abstract: The case reports present the endodontic management of two maxillary first molars with six canals. The diagnosis of morphology of multiple canal systems was identified under magnification of the dental operating microscope and was confirmed with the help of cone beam computed tomography. This paper discusses the variations in the canal morphology and the use of the latest adjuncts in successfully diagnosing and treating unusual canal anatomy. 1. Introduction A thorough knowledge of the root canal anatomy, its variations, the presence of additional roots, and unusual root canal morphology is essential, as it determines the successful outcome of endodontic treatment [1]. To ensure the long-term success of root canal treatment, it is essential to access, clean, and fill all of the canal spaces. However, the anatomic complexities and variations are constant challenges for successful endodontic therapy [2]. The morphology of the maxillary first molar has been extensively studied and reported in the literature. Traditionally the maxillary first molar exhibits three roots and three canals. The occurrence of a fourth canal ranges from 50.4% to 95% [3–7] and a fifth canal 2.25% [8], and a few authors have also reported cases with 6 canals [9, 10]. The occurrence of 2 canals in distobuccal root has been less frequent and has been reported in 3.6% of maxillary molars [4, 10, 11]. Palatine root canal variations were well established by Christie et al. [8, 12], who reported the endodontic treatment of maxillary molars with 2 palatine roots and classified these teeth as types I, II, and III, according to root degree of divergence. Others reported cases of maxillary first molar with two canals in each of the three roots [9, 10, 13–15]. The present cases report the successful management of maxillary first molars with three roots and six canals. The clinical findings were confirmed with the help of operating microscope and cone beam computed tomography (CBCT). 2. Case Report 1 A 43-year-old female patient presented with the chief complaint of pain in the left upper back tooth. The pain was continuous and aggravated on heat stimulation. The patient also complained of pain at night. The patient’s medical history was noncontributory. Clinical examination revealed the left maxillary first molar with a deep carious lesion which was tender on percussion. Electric pulp testing gave a premature response, indicative of inflammatory pulpal changes. The radiographic examination revealed a radiolucent lesion on the mesial aspect of the crown extending to the pulp (Figure 1(a)).

Case Reports in Dentistry , 2012, DOI: 10.1155/2012/767582
Abstract: A thorough knowledge of root canal morphology is a prerequisite for the endodontic therapy. The maxillary molars, especially the second molars, have the most complicated root canal system in permanent dentition. There are many variations in canal number and configuration in maxillary molars. Treatment may be unsuccessful because the dentist may fail to recognize the unusual canal configuration. The present paper describes a case of a right maxillary second molar with a canal configuration rarely reported in the literature. The tooth had four roots with four root canals, two individual palatal roots (mesiopalatal and distopalatal) with their own separate canals. The mesiobuccal and distobuccal root had normal anatomy. This paper may intensify the complexity of maxillary molar variation and is intended to reinforce clinician’s awareness of the rare morphology of root canals.
Solitary median maxillary central incisor (SMMCI) syndrome

Orphanet Journal of Rare Diseases , 2006, DOI: 10.1186/1750-1172-1-12
Abstract: The name originally given to this syndrome by Hall et al. [1], "Solitary median maxillary central incisor, short stature, choanal atresia/midnasal stenosis syndrome", is now customarily shortened to the first part of this name: "Solitary median maxillary central incisor syndrome" or SMMCI syndrome, as the other features are not necessarily present in all cases. The use of the full description of the single incisor tooth in the name is important, as it emphasises the unique form and position of this tooth, which is the characteristic and most readily observed feature or trait of the condition.The early observations of this condition [2-8] merely referred to the congenital and hereditary absence of one central incisor. When the association with short stature was recognised in 1976, the name Monosuperoincisivodontic dwarfism was given by Rappaport et al. [9], but it was soon recognised that short stature was not always present in the disorder [10]. The names "single central incisor syndrome" or "single maxillary central incisor" or "single incisor" suggested by other authors [11-15], do not adequately describe the peculiarly formed incisor tooth.To accurately describe the characteristic tooth present in this syndrome, it is necessary to specify:? Solitary: the tooth present exists as the only central incisor tooth in the maxilla.? Median: this tooth is present precisely in the midline of the maxillary alveolus (a single central incisor tooth present to one or other side of the midline indicates that the contralateral tooth has been lost from trauma or disease, or did not continue to develop beyond the cellular stage, the tooth germ being resorbed).? Maxillary: this characteristic tooth occurs only in the maxilla and not in the mandible.? Central Incisor: the tooth is a central incisor tooth, although of unusual crown form and is not a supernumerary tooth (mesiodens).Hence, the acronym SMMCI syndrome.The following circumstances where only one central incisor tooth is pr
