1/4. Atypical migration of an impacted lower third molar.This report describes the atypical migration of an impacted lower third molar tooth in a 42-year-old woman. Serial radiographs showed that, over a period of 13 years, the tooth migrated from its original disto-angular position posterior to and beneath the roots of the adjacent second molar to a more horizontal position beneath the roots of the first permanent molar. The tooth was surgically removed under general anaesthesia, with biopsy and curettage of soft tissue found in the bone posterior to the tooth along the path of migration. This pattern of tooth movement is highly unusual in an adult patient.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/4. Gingival fibromatosis and significant tooth eruption delay in an 11-year-old male: a 30-month follow-up.This case report describes the dental management of an unusual case of idiopathic gingival fibromatosis with multiple impacted primary teeth, and the absence of eruption of permanent teeth, in an 11-year-old boy and at the 30-month follow-up. The patient presented with severely enlarged gingival tissues affecting both arches and multiple retained and non-erupted primary teeth. He had already been subjected to localized gingivectomies at the ages of 7 and 9 years. He had no known syndrome and there was no family history of any similar disorder. The patient was treated under general anaesthesia to remove the excessive gingival tissues using apically positioned flaps. During the surgical procedure, over-retained and unerupted impacted primary teeth were extracted in order to facilitate the eruption of the permanent successors. Two years postoperatively, there was no recurrence of the gingival enlargement. Overdentures were then constructed because none of the permanent teeth had yet erupted. Furthermore, pre-eruptive coronal resorption was detected radiographically affecting the crown of the unerupted 36. Thirty months postoperatively, no recurrence of gingival enlargement was seen, but the permanent teeth had still not erupted.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
3/4. Large central osteoma of the maxillary antrum.The aim of this report is to describe a case presenting with complaints of orbital pain, altered facial sensation, nasal obstruction and unilateral spontaneous nose bleeding. Panoramic radiography and computerized tomography disclosed a large pedunculated heterogeneous mineral opacity with two impacted molar teeth invading the maxillary sinus. The patient was operated on under general anaesthesia. Microscopic examination of the surgical specimen revealed relatively dense, compact bone with sparse marrow tissue that was diagnosed as osteoma. Clinical characteristics and biological behaviour of this lesion were evaluated with special regard to the reliability of imaging modalities and surgical procedures.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
4/4. facial nerve paralysis after impacted lower third molar surgery: a literature review and case report.facial nerve paralysis (FNP) is the most common cranial nerve disorders and it results in a characteristic facial distortion that is determined in part by the nerves branches involved. With multiples etiologies, these included trauma, tumor formation, idiopathic conditions, cerebral infarct, pseudobulbar palsy and viruses. FNP during dental treatment is very rare and can be associated with the injection of local anesthetic, prolonged attempt to remove a mandibular third molar and subsequent infection. We report a case of a 21 years-old black woman who developed a Bell's palsy after an impacted third molar surgery under local anaesthesia, present a FNP classified like a grade IV by the House-Brackmann's grading system. The treatment was based of prescription of a cytidine and uridine complex (NUCLEO CMP tm) one tablet twice per day and a close follow up. Three months later that had beginning the treatment, the patient recovery her normal facial muscle activity.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
