1/84. Cystic management in a 10-year old child. cysts are among the most common lesions found in the oral cavity. These may be developmental in origin or secondary to chronic infections. Untreated, cysts may expand causing local tissue destruction and deformities. Basically, two treatment methods are employed. Enucleation and/or Marsupialization. The following case involves a child treated at the College of dentistry, University of the philippines, for a large cystic lesion involving the permanent cuspid and the deciduous dentition. The lesion was accidentally discovered on a panoramic radiograph. The child underwent extraction of deciduous teeth and marsupialization, which later helped in the eruption of the malposed permanent teeth. ( info) |
| 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. ( info) |
3/84. Two radicular cysts associated with endodontically treated primary teeth: rationale for long-term follow-up. Although radicular cysts are relatively rare, they do occur. In addition, it appears that these lesions present in association with endodontically treated primary teeth. As shown in this paper and previous reports, cysts can be associated with a variety of pulp therapies. These lesions can lead to bony expansion and resorption. Radicular cysts may also cause displacement and damage to the developing permanent dentition. Given the severity of these sequelae it is prudent to recommend regular radiographic examination of primary teeth that have undergone pulp therapy. ( info) |
4/84. Bilateral pneumothorax with extensive subcutaneous emphysema manifested during third molar surgery. A case report. This report describes a case of bilateral pneumothorax with extensive subcutaneous emphysema in a 45-year-old man that occurred during surgery to extract the left lower third molar, performed with the use of an air turbine dental handpiece. Computed tomographic scanning showed severe subcutaneous emphysema extending bilaterally from the cervicofacial region and the deep anatomic spaces (including the pterygomandibular, parapharyngeal, retropharyngeal, and deep temporal spaces) to the anterior wall of the chest. Furthermore, bilateral pneumothorax and pneumomediastinum were present. In our patient, air dissection was probably caused by pressurized air being forced through the operating site into the surrounding connective tissue. ( info) |
5/84. CT analysis of a complicated nasopalatine duct cyst. A study was conducted to evaluate CT imaging in differentiating nonodontogenic nasopalatine duct cysts from odontogenic radicular cysts. The patient's palatine cystic lesion was analyzed by CT and excised with postoperative microscopic identification. CT findings of a nasopalatine cyst are midline location, smooth expansion with sclerotic margins and displacement of teeth apices. Radicular cysts differ in that the teeth apices are within the cyst rather than being displaced. We concluded that differentiation is clearly demonstrated by CT images. ( info) |
6/84. Red man syndrome during administration of prophylactic antibiotic against infective endocarditis. Red man syndrome (RMS) is the occurrence flushing, pruritus, chest pain, muscle spasm or hypotension during vancomycin infusion. It usually happens as a result of rapid infusion of the drug but may also occur after slow administration. The frequency and severity of this phenomenon diminish with repeated administration of vancomycin. A case is presented whereby RMS occurred while prophylactic antibiotic against infective endocarditis was administered. ( info) |
7/84. 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.

8/84. 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. ( info) |
9/84. Delayed eruption of premolars with periodontitis of primary predecessors and a cystic lesion: a case report. Apical periodontitis after pulp therapy in a primary tooth can cause delayed eruption of the permanent successor. A case of bilateral delayed eruption of mandibular premolars is presented. The patient. a 13-year-old girl, was referred by her dentist. Oral findings showed that the right first and left second primary molars were retained. Other premolars had erupted. An orthopantomogram revealed apical periodontitis, affecting both retained primary molars. The right first mandibular premolar was impacted against the alveolar bone and root of the second premolar, and there was a large cystic lesion in close association with the left second mandibular premolar. Both primary molars were extracted, and the cystic lesion was treated by marsupialization. Fenestration and traction were performed on the right first premolar. Correct tooth alignment was achieved with orthodontic appliances. If the problem had been detected earlier, treatment of the premolars might have been easier. Clinical and radiological follow-up, therefore, of primary teeth that have undergone pulp therapy procedures should be performed until eruption of succedaneous teeth. ( info) |
| 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. ( info) |
