1/5. Maxillary cyst associated with an invaginated tooth: a case report and literature review.Dental invagination or dens in dente is a rare malformation with a widely varied morphology. Radiographically, the affected tooth shows an infolding of the enamel and dentin that can extend to within the pulp cavity and the root and sometimes to the root apex. It can occur in both primary and permanent teeth, and its prevalence is reported to be 1.7% to 10%. The dental anomalies observed in association with dental invagination include taurodontia, microdontia, supernumerary teeth, gemination, and dentinogenesis imperfecta. This article presents a clinical case in which a radiographic finding could be compatible with the presence of a nasopalatine or globulomaxillary cyst and a dens in dente. It was decided to extract the invaginated tooth, and by 15 days postextraction, the radiolucid area had completely disappeared. The complex surgery that would have been required to remove the patient's supposed cyst was thus avoided. Clinical and radiographic examination is suggested before making further decisions that could complicate treatment when a lesion is associated with other dental anomalies.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/5. Diagnostic dilemma: an unusual presentation of an infected nasopalatine duct cyst.The pertinent literature on nasopalatine duct cysts is reviewed. A case is reported in which a nasopalatine duct cyst infected by actinomyces presented clinically with unusual features. The clinical findings could have been confused with an early acute periapical abscess arising from an incisor tooth. The relevant aspects of diagnosis are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
3/5. A diagnostic case involving an incisive canal cyst.An incisive canal cyst was misdiagnosed as an endodontic lesion. The patient's chief complaint was pain on mastication with increasing intensity for the last 2 days. The single original periapical radiograph revealed a well-circumscribed radiolucency related to the apex of the maxillary right central incisor. The patient was referred with a request for endodontic therapy. A subsequent angled radiograph revealed an interroot location of the lesion, and pulp testing showed a normal response. The patient was then referred for surgical treatment. Following removal of the lesion, the histopathologic examination confirmed the diagnosis of an incisive canal cyst. One-year follow-up showed complete healing and maintained tooth vitality, and the patient was asymptomatic.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
4/5. Adenomatoid odontogenic tumor mimicking a globulo-maxillary cyst.A case of an adenomatoid odontogenic tumor (AOT) simulating a globulo-maxillary cyst is described. Clinical, radiographic and microscopic findings as well as the differential diagnosis are discussed. The present case brings the number of AOT cases without any relationship to an impacted tooth to 23; the number of cases resembling a globulo-maxillary cyst to 6.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
5/5. Median palatine cyst.Median palatine cysts are rare, nonodontogenic lesion of the hard palate that do not involve the palatine papilla or incisive canal and that usually present as asymptomatic, fluctuant swellings. They may involve the floor the nasal cavity but are treated by simple enucleation, without recurrence. They are composed histologically of a fibrous collagenous tissue wall, with infiltration of chronic inflammatory cells, and lined by stratified squamous and/or respiratory epithelium. They are differentiated from the nasopalatine and other anterior maxillary cysts by the following diagnostic criteria: Appears grossly to be symmetrical along the midline of the hard palate. Located posterior to palatine papilla. Radiographically ovoid or circular in appearance. Not intimately associated with a nonvital tooth or found to have any communication with the incisive canal. Shows no histologic evidence of nerve trunks, large vascular spaces, hyaline cartilage, or accessory salivary gland tissue in the cyst wall.- - - - - - - - - - ranking = 0.16666666666667keywords = tooth (Clic here for more details about this article) |
