1/52. Case report of regional alveolar bone actinomycosis: a juvenile periodontitis-like lesion.BACKGROUND: Cervicofacial actinomycosis infection most often involves the mandibular bone and rarely the alveolar crest. methods: We describe a 14-year-old patient who had actinomycosis involving the alveolar bone at the left lower dental quadrant region. Resembling juvenile periodontitis, it was difficult to diagnose properly and resulted in devastating dental and periodontal consequences: loss of one tooth with most of its adjacent regional alveolar bone, severely compromising the support of two other teeth. RESULTS: With the diagnosis came successful treatment, including surgical removal of the soft and hard tissues with concomitant prolonged penicillin administration. CONCLUSIONS: We feel that this case should raise the interest and concern of both the periodontist and the general practitioner so that early diagnosis can be obtained, significantly improving the clinical outcome.- - - - - - - - - - ranking = 1keywords = periodontitis (Clic here for more details about this article) |
2/52. actinobacillus actinomycetemcomitans-associated peri-implantitis in an edentulous patient. A case report.BACKGROUND: peri-implantitis is a risk factor for implant loss. Late bacterial infection of the peri-implant tissues and loss of alveolar bone in edentulous patients is caused by commensal oral anaerobic bacteria. In partially edentulous patients, porphyromonas gingivalis and occasionally actinobacillus actinomycetemcomitans are associated with peri-implantitis lesions. AIMS: To investigate the microbiology of a peri-implantitis case in an edentulous patient. methods: Anaerobic culture techniques and selective culture techniques for A. actinomycetemcomitans were used to study the peri-implant microflora at sites with and without bone loss. RESULTS: An anaerobic peri-implant microflora with several putative periodontal pathogens was found at sites with bone loss. Furthermore, a metronidazole-resistant A. actinomycetemcomitans was isolated. The A. actinomycetemcomitans infection did not respond to systemic doxycycline therapy, despite good susceptibility in vitro. CONCLUSIONS: The present case of severe A. actinomycetemcomitans-associated peri-implantitis shows the importance of pre-operative infection control. The findings in this case show that remaining teeth affected by periodontitis can be a serious risk factor for peri-implantitis.- - - - - - - - - - ranking = 0.2keywords = periodontitis (Clic here for more details about this article) |
3/52. hemangioma of the mandible presenting as a periapical radiolucency.A case of an hemangioma of the mandible in a 53-yr-old female patient is presented. The lesion was removed, and no atypia or mitotic cells were found. The excision was curative, and the overall prognosis was excellent. A differential diagnosis of radiolucent periapical lesions of the mandibular symphysis is presented.- - - - - - - - - - ranking = 0.50391493577708keywords = periapical (Clic here for more details about this article) |
4/52. Garre's osteomyelitis of an unusual origin in a 8-year-old child. A case report.Garre's osteomyelitis is a type of chronic osteomyelitis that primarily affects children and adolescents. Although the disease is well described in the dental literature and is usually associated with an odontogenic infection resulting from caries, a number of other causative factors have been occasionally reported, such as a dental extraction or a mild periodontitis. There have also been cases of unknown aetiology. This paper describes a case of Garre's osteomyelitis in an 8-year-old child, in whom the condition arose following a local periodontal infection in an ectopically erupting first permanent molar that was in infraocclusion. The lesion remained unresolved for a period of over 6 months as a result of misdiagnosis, following a number of unsuccessful treatment attempts. Identification of the true cause and treatment through periodontal surgery resulted in lesion resolution and resolved the diagnostic problem. dentists should be aware that the periodontium may be a potential source of infection for Garre's osteomyelitis in children, particularly in the presence of ectopically erupting posterior teeth. In such cases, periodontal treatment should be sufficient to treat the disease and extraction of the tooth involved may not be necessary.- - - - - - - - - - ranking = 0.2keywords = periodontitis (Clic here for more details about this article) |
5/52. Treatment of a human transosseous mandibular defect by guided bone regeneration.The treatment of through-and-through human periapical lesions by barrier membrane techniques has not been reported in the periodontal literature. However, periodontists frequently perform this treatment. The authors present a case that demonstrates radiopacity after regeneration surgery of a human periapical transosseous mandibular defect, suggesting local bone regeneration. The surgical technique performed in this case was based on the principles of guided bone regeneration using a demineralized freeze-dried bone membrane (DFDBM). The bone membrane acted as an efficient barrier that excluded the nonosteogenic tissue. Radiographic findings demonstrated bone fill after 8 months.- - - - - - - - - - ranking = 0.20156597431083keywords = periapical (Clic here for more details about this article) |
6/52. Central (intraosseous) adenoid cystic carcinoma of the mandible: report of a case with periapical involvement.Primary intraosseous salivary gland tumors are rare, with mucopidermoid carcinoma being the most frequent histotype. The authors present a case of adenoid cystic carcinoma, located in the mandibular incisor region, associated with pain. Endodontic treatment resulted in increased pain and progressive mandibular expansion. An apicoectomy was conducted, and an intraosseous adenoid cystic carcinoma was diagnosed at histological examination. The patient was treated by wide surgical resection, and is alive and well without recurrences or distant metastases 14 yr after the original diagnosis. The case presented herein calls attention to the preoperative clinical diagnosis of periapical lesions. Radiologically, focal sclerosing osteitis, cementoblastoma, cementifying and ossifying fibroma, periapical cemental dysplasia, complex odontoma, and calcifying epithelial odontogenic tumor should be considered in the differential diagnosis. In addition the unusual occurrence of salivary gland tumors in intraosseous location stresses the importance of systematic histological examination of any tissue sample obtained after endodontic procedures.- - - - - - - - - - ranking = 0.60469792293249keywords = periapical (Clic here for more details about this article) |
7/52. 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 = 0.10078298715541keywords = periapical (Clic here for more details about this article) |

9/52. Facial sinus of dental origin: a case report.Sinus tracts of dental origin opening on the skin can be a diagnostic challenge. A delay in correctly diagnosing these lesions can result in ineffective and inappropriate treatment; however, if recognized early, the sinus tract usually resolves after appropriate endodontic therapy or extraction. We report a case of a cutaneous sinus tract secondary to a periapical abscess of the mandibular first molar tooth. The case was successfully treated by extraction and the sinus tract healed.- - - - - - - - - - ranking = 0.10078298715541keywords = periapical (Clic here for more details about this article) |
10/52. Proliferative periostitis of Garre: Report of a case.Proliferative periostitis of Garre is described as a productive and proliferative inflammatory response of periosteum to infection or other irritation. This can be odontogenic or non-odontogenic in nature. This is a case report of an odontogenic periostitis resulting from periapical inflammation of endodontic origin. It was successfully treated by nonsurgical endodontics. Antibiotic therapy was not used during the treatment of this patient.- - - - - - - - - - ranking = 0.10078298715541keywords = periapical (Clic here for more details about this article) |
