2/24. Computerized tomography in the management and follow-up of extensive periapical lesion.Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.- - - - - - - - - - ranking = 1.2keywords = periapical (Clic here for more details about this article) |
3/24. eosinophilic granuloma as a form of inflammatory reaction. A case report.eosinophilic granuloma consists of the proliferation and/or accumulation of langerhans cells in the bones, generally of the cranium and face, as a uni- or multifocal cystic lesion. It is considered to be a localized chronic form of Langerhans cell disease. The most frequent oral location is the posterior part of the mandible, where the bone lesion often gives rise to lesions of the overlying soft tissues. We report a case showing bilateral involvement of the upper jaw and unilateral involvement of the mandible. The eosinophilic granulomas arose in association with odontogenic periapical infectious processes, suggesting that this disorder may be a form of inflammatory response.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
4/24. Case report: a large radicular cyst involving the entire maxillary sinus.Cysts of the maxillary sinus of odontogenic origin have been well-documented in the literature. Most of these lesions involve the apex of the offending tooth and appear as a well-defined periapical radiolucency. Presented here is a case of an unusually large lesion, which involved the entire maxillary sinus and extended into the floor of the nose. The lesion also caused paresthesia on the affected side. The lesion was removed with conservative treatment without any postoperative complications.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
5/24. Case challenge. Chronic maxillary inflammation.A 30-year old male was referred by a dental practitioner to the Department of Oral radiology at the University of Lund, sweden, for a radiological evaluation of chronic symptoms of inflammation on the right side of the maxilla. According to the patient, at age 12 he had surgery to remove a non-erupted maxillary right second premolar. Postoperatively, a draining sinus tract appeared on the buccal aspect of the alveolar process. Thirteen years later, at age 25, surgery was again performed and the sinus tract reappeared. Intermittent discharge of exudate from the sinus tract occurred since the second surgery. Clinical and radiological examinations were conducted prior to a third surgery. The clinical examination revealed pus draining from the tract located on the buccal aspect of the alveolar process between the right maxillary first molar and first premolar. The radiological examination included periapical radiographs of the right maxillary first premolar and canine, a panoramic radiograph, and frontal tomograms of the maxillary right premolar area.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
6/24. Adenomatoid odontogenic tumor mimicking a periapical (radicular) cyst: a case report.The adenomatoid odontogenic tumor (AOT) is a benign (hamartomatous), noninvasive lesion with slow but progressive growth. A rare subvariant of the extrafollicular type of AOT may mimic periapical disease radiographically. We report on a 15-year-old girl with a periapical radiolucent lesion affecting teeth 7 and 8 initially suspicious of periapical disease, although clinical findings seemed to indicate a nonendodontic lesion. An exploratory surgical approach was chosen, and the final diagnosis of the removed noncystic tissue mass was microscopically confirmed to be an AOT.- - - - - - - - - - ranking = 1.4keywords = periapical (Clic here for more details about this article) |
7/24. 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 = 0.2keywords = periapical (Clic here for more details about this article) |
8/24. Diffuse sclerosing osteomyelitis in the maxilla: case report.A case of diffuse sclerosing osteomyelitis (DSO) in the maxilla of a 25-year-old male is presented. His chief complaint was recurrent painless swelling in the maxillary right molar region over a 3-year-period. The periapical and panoramic radiographs of the right maxilla showed diffuse sclerotic areas. Computed tomography (CT) indicated a high density area in the right maxilla. Although the tentative diagnosis was fibrous dysplasia on the basis of history, clinical symptoms and radiologic examination, the biopsy results supported chronic diffuse sclerosing osteomyelitis. The maxillary location and the painless course of the lesion in a male patient is a rare occurrence.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
9/24. Peripheral odontogenic keratocyst.BACKGROUND: An odontogenic keratocyst can develop at virtually any site in the jaws and is of concern because of its aggressive clinical behavior. It represents 3% to 12% of all odontogenic cysts. This paper describes the rare peripheral presentation of an odontogenic keratocyst localized to the maxillary anterior gingiva and its differential diagnosis. methods: A patient presented with a round yellow nodule on the maxillary gingiva between the left canine and first premolar. Clinical examination ruled out periapical abscess, periodontal abscess, and lateral periodontal cyst. A differential diagnosis included a gingival cyst, neuroma, neurilemoma, and mesenchymoma. The cyst ruptured during excisional biopsy revealing contents typical of an odontogenic keratocyst (OKC). histology confirmed the peripheral OKC diagnosis. A conservative surgical treatment was performed assuming a less aggressive clinical course for the peripheral odontogenic keratocyst. Close follow-up was planned. RESULTS: To our knowledge, only 13 cases of peripheral OKC have been reported in the literature. Presently it is unknown if the peripheral variant shares the aggressive clinical behavior and recurrence rate of intraosseous OKC. CONCLUSION: This paper may contribute to the limited clinical knowledge base for the peripheral odontogenic keratocyst and assist clinicians in the identification and management of such lesions.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
10/24. aggressive periodontitis in a 16-year-old Ghanaian adolescent, the original source of actinobacillus actinomycetemcomitans strain HK1651 - a 10-year follow up.The highly leukotoxic JP2 clone of actinobacillus actinomycetemcomitans is strongly associated with periodontitis in adolescents. Availability of the dna sequence of the complete genome of A. actinomycetemcomitans strain HK1651, a representative strain of the JP2 clone (http://www.genome.ou.edu/act.html), has provided new possibilities in basic research regarding the understanding of the pathogenesis of A. actinomycetemcomitans in periodontitis. This case report describes the periodontal treatment of the original source of A. actinomycetemcomitans HK1651, a 16-year-old Ghanaian adolescent girl with aggressive periodontitis. The bacterial examination involved polymerase chain reaction analysis for presence of JP2 and non-JP2 types of A. actinomycetemcomitans. The treatment, including periodontal surgery supplemented by antibiotics, arrested the progression of periodontitis for more than 10 years. Initially, infection by A. actinomycetemcomitans, including the JP2 clone, was detected at various locations in the oral cavity and was not limited to the periodontal pockets. Post-therapy, the JP2 clone of A. actinomycetemcomitans disappeared, while the non-JP2 types of A. actinomycetemcomitans remained a part of the oral microflora.- - - - - - - - - - ranking = 0.65454329998093keywords = periodontitis (Clic here for more details about this article) |
