Dens Invaginatus

AbstractA 14-year female presented with an atypical looking tooth #7 with a sinus tract on tooth #8. A gutta-percha point inserted into the sinus tract confirmed the affected tooth #7. A radiographic examination of tooth showed a lateral radiolucency with respect to tooth #7. Cone-beam computed tomographic imaging was done for the three-dimensional reconstruction analysis. Dens invaginatus (Oehler’s type III) with pulp necrosis and chronic apical periodontitis was the definitive diagnosis. Use of the dental operating microscope and ultrasonics helped in the removal of the invaginated structure. At the two year follow-up, no clinical and radiographic evidence of infection was observed.

SummaryBackground/Aim: Dens invaginatus is a developmental anomaly of teeth. The endodontic treatment of these teeth may be difficult because of adversity in accessing the root canals and also complicated variations of internal structure. In this case, the report is presented the nonsurgical management and follow-up of a tooth with class II dens invaginatus with an open apex and sinus tract.Case Report: In the radiographic examination, there are two root canals; a primary (main) canal and an invaginated canal. The main canal wide-open at the portal of exit and associated with a large chronic periapical lesion extending to the apex of the maxillary left central incisor. An invaginated canal was not reaching the apex. In a clinical examination, a sinus tract was detected in the labial gingiva. After apexification with using MTA was applied, the endodontic treatment was completed. In 12 month recall, a gray discoloration was detected and internal bleaching with 35% hydrogen peroxide was applied. Finally, the tooth was restored using composite resin. 12 months follow-up radiographs revealed resolution of periapical radiolucency, trabecular bone formation, and closure of the root apex with the totally asymptomatic tooth.Conclusions: The case report shows that tooth with DI that has wide apex and sinus tract can be treated with non-surgical methods, such as immature tooth without anomalies.

SummaryThis report describes the treatment of traumatic carpal hyperextension in a giant breed dog by pancarpal arthrodesis using a custom- made Fixin locking plate, created with the aid of a three-dimensional plastic model of the bones of the antebrachium produced by rapid prototyping technology.A three-year-old 104 kg male Mastiff dog was admitted for treatment of carpal hyperextension injury. After diagnosis of carpal instability, surgery was recommended. Computed tomography images were used to create a life-size three-dimensional plastic model of the forelimb. The model was used as the basis for constructing a customized 12-hole Fixin locking plate. The plate was used to attain successful pancarpal arthrodesis in the animal.Radiographic examination after 74 and 140 days revealed signs of osseous union of the arthrodesis. Further clinical and radiographic follow-up examination three years later did not reveal any changes in implant position or complications.

This paper presents a case report of a left mandibular second premolar with three canals and three different apical foramina. A 39-year-old male patient presented to our clinic with pain in the mandibular left second premolar. Initially, pain was caused by cold stimulus and later was spontaneously. The intraoral clinical examination revealed a fractured amalgam restoration with occlusal caries. Percussion and cold (Endo-Frost) tests were positive. The radiographic examination showed the presence of two roots. The probable diagnosis was an acute pulpitis. After access cavity, it was observed remaining roof of the pulp chamber and mild bleeding in the tooth lingual area, indicating the possible presence of a third canal. The endodontic treatment was completed in a single session using Root ZX apex locator and K3 NiTi rotary system with surgical diameter corresponding to a .02/45 file in the three canals and irrigation with 1% sodium hypochlorite. The canals were obtured with gutta-percha cones and Sealer 26 using the lateral condensation technique. After 1 year of follow-up, the tooth was asymptomatic and periapical repair was observed radiographically. Internal alterations should be considered during the endodontic treatment of mandibular second premolars. The correct diagnosis of these alterations by the analysis of preoperative radiographs can help the location of two or more canals, thereby avoiding root therapy failure.

Reconstruction of mandibular defects following tumor resection in infants is a particular challenge. Although autogenous rib grafts have no relevance in the restoration of mandibular bone defects occurring after ablative tumor surgery due to limited bone stock and the availability of other donor areas, they are a useful surgical alternative following tumor surgery in infants. We here report on a 2, 5, 8, and 15-year follow-up of four children who were diagnosed with benign tumors of the mandible with osseous destruction at the age of 4, 6, 15, and 18 months, respectively. Histologic diagnoses were melanotic neuroectodermal tumor ( n=2), hemangioendothelioma of the mandible ( n=1), and ameloblastoma ( n=1). Following continuity resection of the mandible, lateromandibular bone defects were restored using autogenous rib grafts. Both clinical and radiologic follow-up visits were performed for all children to assess growth of the facial skeleton and the mandible. One child was already further reconstructed using bone augmentation at the age of 15 years. Cephalometric measurements on panorex films and three-dimensional computed tomographic scans revealed a slight vertical growth excess and transversal growth inhibition of the reconstructed mandible compared with the nonoperated side. Although further growth of rib grafts is difficult to predict and occlusal disharmony may occur due to physiologic maxillary growth and growth of the unaffected mandible, we believe that autogenous rib grafts can be ideally used for the restoration of mandibular continuity defects in newborns and young children. Clinical follow-up visits on a yearly basis and orthodontic controls are useful for early orthodontic treatment of growth deficits. Further corrective surgery with bone augmentation or osseous distraction is required following completion of growth of the facial skeleton.

Background: To overcome disadvantages of the older surgical model, we invented a new three-dimensional (3D) correction surgery design after studying computer-aided 3D model analysis. Methods: Three-dimensional reconstruction was carried out for computed tomographic (CT) scans of patients with normal bilateral lower extremities; an anatomical model was established; and the normal values of 3D anatomic parameters of the lower-extremity joints were measured with computer assistance. An osteotomy procedure was simulated using a computer, appropriate osteotomy site, and osteotomy angle, and an osteotomy method was selected. Computer-assisted design (CAD) was used to produce an individualized auxiliary osteotomy template for guiding the osteotomy and an auxiliary correction template for guiding correction surgery. Finally, we accurately performed surgery according to the preoperative design. Results: All surgeries were performed successfully and postoperative x-ray films showed satisfactory deformity correction. Conclusions: Computer-aided lower-extremity joint correction surgery is more accurate and convenient than conventional surgery.

Internal root resorption is a chronic inflammatory process initiated within the pulp space with the loss of dentin. This condition demands a comprehensive understanding of the pathologic process, so as to identify the cause and arrest the resorptive phenomena. It is a rare occurrence, asymptomatic, with slow progression, detected through routine radiographic examination, where it appears as a radiolucent lesion. This paper reports a clinical case of inflammatory internal root resorption in the premolar tooth. Because it is asymptomatic, internal root resorption needs an early diagnosis in order to institute the endodontic treatment before the process compromises the remaining mineralized structures of the tooth. Biodentine was used to reinforce the weaker structures in the root. Thermoplasticised gutta-percha was used to completely obturate the defect. Ten-month follow-up showed arrest of internal root resorption.
