Premolarized double dens in dente in albinism--a case report. (2/21)

Dens in dente are known to be associated with many dental abnormalities such as taurodontism microdontia, gemination, and dens evaginatus. This paper describes a rare case of double dens in dente in a lateral incisor with crown morphology similar to a premolar present in a patient with features of albinism. Problems associated with this condition and their management is discussed.  (+info)

Nonsurgical management of two unusual cases of dens in dente. (3/21)

The management of two unusual cases of dens invaginatus in a maxillary and a mandibular lateral incisor with a periradicular lesion are reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus, nonsurgical root canal treatment was performed successfully. Furthermore essential clinical considerations and treatment options are suggested. Early diagnosis and management are important to avoid complications.  (+info)

Combined endodontic therapy and surgery in the treatment of dens invaginatus Type 3: case report. (4/21)

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively and should be treated by both endodontic therapy and surgery. A case of dens invaginatus Type 3 in a maxillary lateral incisor with a periapical lesion and its successful treatment by these combined methods is reported.  (+info)

Unicystic ameloblastoma of the maxilla: a case report. (5/21)

Unicystic ameloblastoma is believed to be less aggressive and responds more favorably to conservative surgery than the solid or multicystic ameloblastomas. This report is a rare case of unicystic ameloblastoma of the maxilla that was treated by enucleation under suspicion of a radicular cyst related to a dens in dente. The neoplastic nature of the lesion became evident only when the enucleated material was available for histologic examination. With this report, the authors illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the maxilla, among them - inflammatory radicular cysts, odontogenic keratocysts, adenomatoid odontogenic and unicystic ameloblastoma. Relevant diagnostic problems and choice of treatment of unicystic ameloblastoma are presented along with a review of the literature.  (+info)

Impaction of permanent mandibular second molars in ethnic Chinese schoolchildren. (6/21)

OBJECTIVE: To investigate the prevalence of impaction of permanent mandibular second molars and associated dental and radiographic characteristics of Chinese children in Hong Kong. MATERIALS AND METHODS: Dental and radiographic records of a group of Chinese schoolchildren were studied retrospectively. Cases of impaction of 1 or both permanent mandibular second molars were selected. Demographic data and dental and radiographic findings were recorded and analyzed. The angle of the impacted second molars was measured on panoramic radiographs. RESULTS: Among the 3,053 records reviewed, 32 cases of impaction of permanent mandibular second molars were identified and studied. Mesial impaction was found in all but 1 case. The angle of the mesially impacted teeth ranged from 13 degrees to 75 degrees . Mandibular crowding and the presence of third molars were common. Dens evaginatus, taurodontism and Class III malocclusions were significantly more prevalent in the study group than in the general population of Chinese children of similar age. CONCLUSIONS: The prevalence of impaction of permanent mandibular second molars in Chinese children was estimated to be 1%. Thorough and regular examination of the child"s developing dentition is recommended to diagnose dental impaction promptly.  (+info)

Double dens invaginatus in an impacted molariform supernumerary tooth: a unique case. (7/21)

Dens invaginatus is a relatively rare developmental anomaly affecting usually the permanent maxillary lateral incisor. Various factors have been put forward regarding its pathogenesis. Involvement of crown/root has been reported as the coronal and radicular variety of dens invaginatus. One of the rarest variant is the Double dens invaginatus and only a few cases have been reported in the literature.This article focuses on a case of double dens invaginatus in an impacted maxillary anterior supernumerary tooth, the associated complications and its management.  (+info)

Nonsurgical treatment of periapical lesion associated with type III dens invaginatus using calcium hydroxide: a case report. (8/21)

Dens invaginatus is a developmental malformation of teeth, probably resulting from an infolding of the papilla during tooth development. It predisposes the tooth to develop caries and periapical pathosis. Root canal therapy may present many problems because of the complex anatomy of the teeth. The purpose of this case report is to describe the endodontic treatment of an Oehlers type III dens invaginatus that perforated into the apical area. Calcium hydroxide powder mixed with normal saline, was used as an intracanal medicament. This eradicated the pathogenic microorganisms in the invagination and preserved the vitality of the tooth, allowing gutta-percha obturation in the invagination.  (+info)
