    Abstract:

    Abstract Introduction The aim of this study was to analyze and characterize root canal morphology of Maxillary Molars of the Brazilian population using cone-beam computed tomographic (CBCT) imaging. Methods Patients referred for a CBCT radiographic examination for accurate diagnosis and treatment planning were enrolled in the study. A total of 620 healthy, untreated, fully developed Maxillary first and Second Molars were included (314 first Molars and 306 Second Molars). The following observations were recorded: (1) number of roots and their morphology, (2) number of canals per root, (3) fused roots, and (4) primary variations in the morphology of the root canal systems. Results First and Second Molars showed a higher prevalence of 3 separate roots, mesiobuccal, distobuccal, and palatal, with 1 canal in each root (52.87% and 45.09%, respectively). Two canals in the mesiobuccal roots represented 42.63% of teeth, whereas mesiobuccal roots of Second Molars presented 2 canals in 34.32%. The most common anatomic variation in the Maxillary first Molar was related to the root canal configuration of the mesiobuccal root, whereas the root canal system of the Maxillary Second Molar teeth showed more anatomic variables. Conclusions Mesiobuccal roots of Maxillary Molar teeth had more variation in their canal system than the distobuccal or palatal roots. The root canal configuration of the Maxillary Second Molars was more variable than the first Molars in a Brazilian population. CBCT imaging is a clinically useful tool for endodontic diagnosis and treatment planning.

    Co-Authors: Santosh Patil, Bharati Doni, Sumita Kaswan, Farzan Rahman
    Abstract:

    Objectives: Taurodontism affects primarily Molars and preMolars in both the deciduous and permanent dentition. The aim of the study was to assess the prevalence of taurodontism in the North Indian population. Study Design: 4143 patients were studied by analyzing the panoramic radiographs for the presence of taurodontism which is defined as the presence of an apically displaced pulp chamber and the tooth lacks the usual constriction at the cementoenamel junction. The age of the patients ranged from 13 to 38 years with a mean age of 21.8 years. Results: Taurodontism was found in 17 patients with a prevalence of 0.4 % of which 0.21 % were males and 0.19% females. Taurodonts were significantly more common in the maxilla (65.6%) than in the mandible (34.4%) (p<0.05) and the Maxillary Second Molar (34.4%) was the most commonly involved tooth. According to the morphology hypotaurodonts were most common (75%) but there was no significant difference in males and females (p>0.05). Conclusion: Taurodontism is relatively uncommon in the North Indian population. Further large scale studies need to be carried out to assess its prevalence in the general population.

  • replantation of a Maxillary Second Molar after removal of a third Molar with a dentigerous cyst case report and 12 month follow up
    Journal of Clinical and Experimental Dentistry, 2014
    Co-Authors: David Penarrochaoltra, Amparo Aloyprosper, Maria Penarrochadiago
    Abstract:

    The aim of this study was to describe the replantation of a Maxillary Second right Molar, which had been removed for surgical reasons in order to remove a dentigerous cyst associated with the adjacent third Molar, and the case’s 12-month follow-up. A 51-year-old man presented swelling in the right Maxillary area. Radiographic examination showed a large radiolucency in close proximity to the third Molar, suggesting a follicular cyst. The third Molar was extracted and the cyst underwent curettage. The Second Molar had to be extracted to enable complete removal of the cyst and to achieve primary closure of the wound, which would have been impossible without repositioning the Molar. With this objective, extraoral endodontic treatment was performed, the root-end was resected and prepared with ultrasonic retrotips, and root-end filling was accomplished with MTA before the Molar was replanted. At the 12-month follow-up, the tooth showed no clinical signs or symptoms, probing depth was no greater than 3 mm and radiographic examination showed no evidence of root resorption or periapical lesion.
