There is doubts about the endodontic morphology of the buccal region of the upper second molar when it showed the buccal roots fusioned. This paper was performed to determine the number of root canal when the tooth presents the buccal roots fusioned. Fifthy nine upper second molars that presented the buccal roots fusioned, extracted for different reasons without atention to age, sex or race, was used. After the cross-cuting at the anatomic neck the root canal was opened by endodontic instruments and painted with black ink, for best visualisation. Finaly the roots were sliced with burs in the cervico-apical direction. We found four groups of teeth based in the number of root canal and/or apex foramen.

Background: Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. Case Report: Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up. Conclusion: Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

Intentional replantation is a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this article, intentional replantation is described and discussed as a treatment approach for failed root canal treatment with broken instrument periapically in mandibular second molar.

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.

ABSTRACT Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

Objectives: Cone-Beam Computed Tomography is an alternative imaging technique which has been recently introduced in the field of Oral & Maxillofacial Radiology. It has rapidly gained great popularity among clinicians due to its ability to detect lesions and defects of the orofacial region and provide three-dimensional information about them. In the field of Endodontics, CBCT can be a useful tool to reveal tooth morphology irregularities, additional root canals and vertical root fractures. The objective of this study is to evaluate the root and root canal morphology of the maxillary permanent molars in Greek population using Cone-Beam Computed Tomography.Materials and Methods:273 cone-beam computed tomography (CBCT) images were examined. The number of roots and root canals of the first and second maxillary molars were evaluated. Root canal configuration was classified according to Weine’s classification by two independent examiners and statistical analysis was performed.Results:A total of 812 molars (410 first and 402 second ones) were evaluated. The vast majority of both first and second molars had three roots (89.26% and 85.07%, respectively). Most first molars had four canals, while most second molars had three. In the mesiobuccal roots, one foramen was recorded in 80.91% of all teeth. Other rare morphologic variations were also found, such as fusion of a maxillary second molar with a supernumerary tooth.Conclusion:Within the limitations of this study, it can be concluded that more attention should be given to the detection of additional canals during root canal treatment in maxillary permanent molars. Towards this effort, CBCT can provide the clinician with supplemental information about the different root canal configurations for successful Root Canal Treatment.

The C-shape configuration in molars it’s an anatomical variation that difficult the diagnosis and treatment. The aim of this study was to report a case of C-shape endodontic configuration in mandibular second molar. The radiographic examination of one patient revealed the extent of caries in the mesial aspect of mandibular second molar, without the presence of periapical lesion and was clinically noted the C-shape configuration of the root canal, extending from the mesiobuccal to the distal canal. Endodontic therapy was performed and after the root canal obturation with gutta-percha cones and endodontic cement the tooth was restored. We conclude that the anatomical condition in C-shape, although it brings many difficulties for the endodontic treatment, does not preclude the tooth rehabilitation.

Objectives:Determination of Root canal configuration of maxillary first and second molar teeth was the aim of this study.Study design: An in vitro experimental study.Place and duration of the study:Study was conducted in Gandhara University for a period of six month.Materials and Methods:Specimens were analyzed by sectioning and clearing techniques for evaluation of the pattern and configuration of roots. Dye penetration was the criteria which were then evaluated through microscope.Results:In clearing group, type-I canals are 18% more than sectioning group. While type-II was reversely i.e. 19% more in sectioning group than clearing group.Conclusion:Difference in both the study groups could be mainly due to failure of dye to pass through sclerosed or minute diameter secondary canal in clearing group. This study verifies that method of research has great influence on the results.
