1/25. Focal cemento-osseous dysplasia in the maxilla mimicking periapical granuloma.A case of focal cemento-osseous dysplasia of the maxilla in a 19-year-old man is reported. Clinically, the lesion resembled periapical pathosis of odontogenic origin. The clinical and histopathologic features of cemento-osseous dysplasia are reviewed.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/25. Reddening of the upper central incisors associated with periapical granuloma in lepromatous leprosy.Four years after starting treatment for lepromatous leprosy in england a male Pakistani aged 26 was found to have red discoloration of the upper central incisor teeth. A radiograph suggested periapical abscess on the right with haziness in a corresponding area on the left. Right apicectomy was performed with removal of a solid mass attached to the apex, sections revealing a lepromatous infiltrate with acid-fast fragments of mycobacterium leprae in the cytoplasm of foamy macrophages. Clinical and archaeological evidence for the frequent involvement of these teeth in lepromatous leprosy is reviewed. The upper incisor area is relatively cool, a factor which may be of critical importance for the lodgement and multiplication of this bacillus, as it is in other body sites in lepromatous leprosy.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
3/25. A conservative biopsy technique for periapical lesions.This paper presented a conservative technique for biopsy of periapical lesions. The case report demonstrated the insertion of a flexible microsurgical biopsy forceps through a labial sinus tract into a lesion for removal of specimens for histopathological evaluation. This limited tissue removal seemed to induce a change from a cyst to a granuloma, as well as stimulate a degree of repair.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
4/25. Development and treatment of retrograde peri-implantitis involving a site with a history of failed endodontic and apicoectomy procedures: a series of reports.Osseointegrated implants provide predictable restorative support for crowns, restorations, prosthesis abutments, and removable dentures. Their widespread use in recent years has produced different types of complications. Retrograde peri-implantitis, a lesion occurring at the periapical area of an osseointegrated implant, has recently been described. This paper presents a series of reports describing the occurrence and management of retrograde peri-implantitis involving implants replacing teeth with histories of failed endodontic and apicoectomy procedures.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
5/25. Charcot-Leyden crystals within a periapical lesion.Transmission electron microscopy revealed the presence of Charcot-Leyden crystals within a periapical lesion, which was assessed histopathologically as consistent with a periapical granuloma that failed to resolve after conventional endodontic treatment. This paper presents the clinical, radiographic, histological, and ultrastructural findings of this case and discusses their potential clinical significance.- - - - - - - - - - ranking = 1.2keywords = periapical (Clic here for more details about this article) |
6/25. 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) |
7/25. The horizontally impacted maxillary canine situated in a labial position.Surgical management of unerupted teeth depends upon a thorough understanding of anatomic, physiologic and pathologic factors. attention has been given to problems of eruption in the maxillary anterior region. It is a region where a variety of anomalies occur. Since the maxillary anterior region influences appearance so greatly, early detection of difficulties and careful planning and treatment can be extremely beneficial to patients. The purpose of this case report is to present a case of maxillary permanent canine impaction in a horizontal displacement that developed after loss of the deciduous canine to chronic apical periodontitis, and incomplete root resorption of the deciduous canine.- - - - - - - - - - ranking = 0.011228673577855keywords = periodontitis (Clic here for more details about this article) |
8/25. Focal cemento-osseous dysplasia involving a mandibular lateral incisor.AIM: To report a case of focal cemento-osseous dysplasia (FCOD) affecting a single tooth misdiagnosed as an inflammatory periapical lesion.SUMMARY: The patient, a black 47-year-old woman complained of pain affecting the right side of the mandible. Routine X-ray examination discovered a periapical radiolucency on the mandibular left lateral incisor (tooth 32), which was otherwise normal and not carious. As the response of this tooth to a vitality test was doubtful, the lesion was diagnosed as a periapical granuloma or cyst secondary to pulpal necrosis. Endodontic treatment and curettage of the periapical lesion were performed, and histological examination of the curettage material revealed a localized osseous dysplasia. KEY learning POINTS: FCOD may rarely affect only one tooth, resembling a periapical granuloma or cyst. Careful diagnosis is of paramount importance in cases of questionable periapical lesions affecting normal-looking teeth, before beginning treatment. FCOD generally requires no treatment. biopsy is warranted in case of doubt.- - - - - - - - - - ranking = 1.2keywords = periapical (Clic here for more details about this article) |
9/25. Periapical radiolucency mimicking an odontogenic cyst.AIM: To present a clinical case of a giant cell lesion located in an unusual site, initially misdiagnosed and treated as an odontogenic cyst. SUMMARY: Periapical radiolucencies often suggest the presence of odontogenic pathosis, usually inflammatory granulomas or cysts. The high frequency of such lesions tends to lead clinicians to arrive at a diagnosis without completing a comprehensive assessment of the patient or carrying out the full range of available diagnostic tests. A case report of a giant cell lesion, which was misdiagnosed and treated initially as an odontogenic lesion because of its unusual location, is presented. KEY learning POINTS: Clinical signs and radiographic appearance are usually sufficient to reach a diagnosis of periapical pathosis. When traditional treatment does not lead to success, a biopsy should be considered to ascertain the diagnosis and allow the correct treatment to be provided. Histological examination of soft tissue removed during endodontic surgery is essential.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
10/25. Echographic evaluation of bone lesions of endodontic origin: report of two cases in the same patient.We report on two periapical lesions of endodontic origin detected in the maxillary bone of the same patient, whose echographic examination was used to address a tentative differential diagnosis between a granuloma and a cystic lesion. The patient on whom two periapical lesions were diagnosed with clinical and conventional radiographic findings and scheduled for endodontic surgery, was also examined using echography and color power doppler at the site of the lesions. The lesions were echographically described in each case according to a scheme from a previous work. A tentative differential diagnosis between a cystic lesion and a granuloma was made. One lesion was described as a cyst, the other as a granuloma. After surgical excision, the lesions were examined under light microscopy. In both cases the two echographic diagnoses were confirmed by the histopathologic examination.- - - - - - - - - - ranking = 0.4keywords = periapical (Clic here for more details about this article) |
