1/19. The treatment of mandibular cysts associated with osteogenesis imperfecta.A fifteen-year-old boy with osteogenesis imperfecta (OI) and dentinogenesis imperfecta also had a big cyst in the mandible and needed surgical therapy. Six months postoperatively we saw a complete regeneration of the bone-structures. We came to the conclusion that cysts which appear independently from the disease of OI can heal after surgical intervention.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/19. myxoma of the jaws. Report of three cases.Odontogenic myxoma is a locally aggressive, uncommon benign tumour which arises from mesenchymal tissues normally present in developing teeth. The most frequent locations of odontogenic myxoma are the posterior regions of the mandible, as well as the condylar region. Since odontogenic myxomas are not associated with any specific clinical or radiological sign, a histopathological examination of the specimen is required for confirmation of the primary diagnosis. We report three cases of myxoma diagnosed during the last 18 years. Two of them were located in atypical regions of the mandible and one was located in the maxilla. Presence of a slow-growing swelling associated with expansion of the bone plates raised suspicion of a tumour in two cases, while in the third patient the myxoma was an incidental finding during radiological examination. Due to the unspecific nature of these lesions, in every case a histopathological examination of the surgical specimen was required for diagnostic confirmation. In one of the three reported cases, we shall underline the need to follow a correct diagnostic work-up of all radiolucent lesions of the jaws, in order to avoid contraindicated therapeutic procedures.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
3/19. radicular cyst associated with a primary molar following pulp therapy: a case report.A radicular cyst arising from the primary second molar and causing displacement of the permanent successor to the lower border of the mandible, with accompanying buccal expansion, was examined clinically and radiographically. Extraction of the primary molar and extirpation of the cyst led to uneventful healing. The primary molar had received pulp treatment with therapeutic agents approximately 1.5 years prior to the patient's first visit. The relationship between pulp treatment and rapid growth of the radicular cyst is discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/19. Malignant pleural mesothelioma metastasis to the mandible.Malignant mesothelioma is a rare tumor arising from the pleura or peritoneum. Distant hematogenous metastasis is seen in more than half of cases, preferentially to the brain, lung, bone and soft tissues [Br. J. Dis. Chest 70 (1976) 246]. There has been only one previous report of this tumor metastasizing to the jaw bone [Pathologica 92 (2000) 273].- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
5/19. Unicystic ameloblastoma: a possible pitfall in periapical diagnosis.AIM: To report a clinical case of unicystic ameloblastoma previously misdiagnosed as radicular cyst. SUMMARY: A 49-year-old white male was referred to a private practitioner complaining of an asymptomatic bony hard swelling of the left posterior mandible. The patient's dental history indicated that his left mandibular first molar had been extracted approximately 10 years previously. At that time, preoperative radiographic examination demonstrated a radiolucent area of 1.5 cm diameter with well-defined margins involving the distal root of tooth 36. The lesion was diagnosed as cystic and surgery for its removal was advised, but not performed. At presentation, radiography demonstrated a well-defined 3 cm diameter radiolucency extending from the second premolar to the second molar. The lesion was enucleated and histopathological examination confirmed a diagnosis of unicystic ameloblastoma. KEY learning POINTS: *Despite a clinical diagnosis of periapical disease of endodontic origin, a nonendodontic lesion may be present. *Unicystic ameloblastoma located on the periapical area of a tooth can lead to a pulp-periapical misdiagnosis, and should be considered in differential diagnosis. *All tissue specimens recovered in apical surgery should be submitted to histopathological analysis.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/19. Paraesthesia of the lip and chin area resolved by endodontic treatment: A case report and review of literature.Lower lip numbness is a symptom that may be due to entirely benign causes, or it may be the first sign of a more sinister problem. It has been reported as being the sole symptom of pathological lesions and metastatic tumours in the mandible.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
7/19. Central neurilemmoma of the jaw in concurrence with radicular cyst: a case report.We report the features of a central neurilemmoma in the mandible of a patient having an inflammatory apical dental (radicular) cyst in the same region. A 29-year-old woman complained of numbness on the right side of the lower lip of 3 months duration and noted following endodontic therapy to the right mandibular first molar tooth. Panoramic radiography revealed a bilocular radiolucency in the right body of the mandible. Excisional biopsy was performed. The histopathology revealed neurilemmoma of the mandible in concurrence with inflammatory apical dental (radicular) cyst. No recurrence was detected during a 1-year follow-up.- - - - - - - - - - ranking = 3keywords = mandible (Clic here for more details about this article) |
8/19. Obturator after marsupialization of a recurrence of a radicular cyst of the mandible.The radicular cyst is the most common odontogenic cyst. We present the case of a 51-year-old man with an extended recurrence of a radicular cyst of the mandible that was treated with marsupialization. Subsequently, an obturator was fitted, and in 10 months a resolution (clinically and radiographically) of the cystic cavity was noticed without any signs of recurrence. The marsupialization is a well-established, nonaggressive treatment of large odontogenic cysts and shows advantages in preserving vital structures, with reduced risk of pathological mandibular fractures. The patient, however, must be compliant and accept the prolonged treatment of marsupialization.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
9/19. Calcifying odontogenic cyst presenting as a lateral periodontal cyst--a case report.We report a case of the calcifying odontogenic cyst occurring on the left anterior mandible of a 41-year-old male with clinical and radiographic features which made it initially to be a lateral periodontal cyst. This unusual presentation of a calcifying odontogenic cyst is discussed and its significance for the clinician is reviewed. A calcifying odontogenic cyst may present some problems for the differential diagnosis both clinically and histopathologically. The differential diagnosis of a lesion occurring in a lateral periodontal location should include the calcifying odontogenic cyst.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
10/19. decompression of a large periapical lesion utilizing an improved drainage device.A decompression device constructed of plastic intravenous tubing attached to an acrylic base and ligated into position with orthodontic ligature wire was used to successfully reduce a large periapical lesion in the anterior mandible.
