1/72. Unusual dental injuries following facial fractures: report of three cases. We report 3 cases of unusual dental injuries following facial fractures. The first patient sustained intrusion of a maxillary incisor into the nasal cavity following a mandibular fracture. The tooth dislocated into the pharynx and was found lodged in the piriform fossa during surgery. The second patient sustained intrusion of molars into the maxillary sinus following maxillary and mandibular fractures. His treatment was delayed due to life-threatening hemorrhage. The third case involved ingestion of multiple avulsed teeth into the alimentary tract following severe maxillofacial fractures. Although the diagnosis was made more than a week after the injury, the patient did not suffer any complications as a result of the dental avulsion. The aim of this report is to emphasize the possibility of associated dental injuries in patients with facial fractures. The trauma surgeon should be cognizant of the importance of carrying out a thorough intraoral examination during the initial evaluation. Any missing tooth should be considered as possibly displaced into other tissue compartments, and must be routinely searched for with x-rays of the skull, cervical spine, chest, and abdomen. If full intrusion injury is suspected, further diagnostic investigation with facial computed tomography scanning may be worth while. ( info) |
2/72. The intubating laryngeal mask for maxillo-facial trauma. We report the successful use of the intubating laryngeal mask airway in a patient with maxillo-facial trauma for whom the facemask and laryngoscope were relatively contraindicated and the fibreoptic scope potentially difficult to use.

3/72. Prosthetic rehabilitation of a warfare facial trauma. This case report presents the prosthetic treatment of a warfare facial trauma patient with the aim of providing satisfactory function, esthetics, and alleviation of deformities. Veneer crowns with rests, root coping, and metal-base partial prostheses were used for the patient therapy and treatment. ( info) |
4/72. Cemental tear treated with guided tissue regeneration: a case report 3 years after initial treatment. Cemental tear is a rare but probably underdiagnosed condition that may be a factor in rapid periodontal breakdown. The present case report describes the regenerative treatment of a periodontal lesion around a mandibular canine in a 50-year-old woman. The preoperative radiograph revealed a small cemental tear within an intrabony lesion. The three-wall bony lesion was treated with a barrier membrane and followed for 3 years. periodontal pocket reduction was 5.5 mm, and attachment gain amounted to 3.5 to 4.5 mm Standardized radiographs showed remarkable, 1.6-mm bone fill of the intrabony lesion. Also, a band of keratinized tissue had formed. ( info) |
5/72. Dilacerated incisors and congenitally displaced incisors: three case reports. Three cases of dilacerated incisors and congenitally displaced incisors are reported. Dilaceration of central incisors occurs following trauma to the deciduous dentition. Generally these teeth are so severely malformed that they have to be extracted. Congenital displacement of the central incisors is an idiopathic condition with a generally favourable prognosis for orthodontic alignment. ( info) |
6/72. A case of dental mutilation. A case of ritual mutilation in a fourteen-year-old Ethiopian girl is described. When the girl was three years old she had frequent stomach problems. According to tribal tradition her illness was thought to arise from her mandibular primary canines and these teeth were removed by a medicine man. The extraction damaged the tooth germs of the succedaneous teeth and resulted in deformed permanent canines. This is the first report of a case of dental mutilation from ethiopia. ( info) |
7/72. Treatment of root perforation by intentional reimplantation: a case report. Intentional reimplantation is defined as a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this paper, intentional reimplantation is described and discussed as a treatment approach to root canal instrument separation in conjunction with root perforation. An 8-year follow-up case report is presented. The reimplanted tooth is now a fixed bridge abutment. Although successful in this case, the intentional reimplantation procedure should be considered a treatment of last resort, that is, when another treatment option is not viable for the treatment of root perforation/instrument retrieval.

8/72. Apex formation during orthodontic treatment in an adult patient: report of a case. This clinical report describes an apexification procedure on a maxillary left central incisor in a 34-year-old male who was also receiving active orthodontic treatment. The pulp of the tooth had become necrotic following a traumatic injury when the patient was 8 years of age. Despite the tooth undergoing active orthodontic repositioning with fixed appliances, root-end closure occurred uneventfully and within 3 years. ( info) |
9/72. Furcation involvement in posterior teeth. This article presents two cases in which different treatments were used for mandibular molars with furcation lesions. In the first case, a conventional amputation treatment of the distal root was performed to save the mesial root as a terminal tooth, which was used as a partial denture abutment. The second case describes a relatively new technique in which a root perforation was filled with graft material (synthetic bioglass) and covered with a resorbable membrane to treat an iatrogenic furcation lesion adjacent to the mesial root. Twelve months after surgery, periapical radiographs of both treated cases showed increased bone density. Follow-up in both cases--30 months in the first case and 12 months in the second--showed no pathological recurrence or clinical dysfunction. Root amputation may provide an alternative to extraction in periodontally involved molars. Synthetic bone replacement materials combined with guided tissue regeneration may also help to correct osseous defects incurred by recent furcation perforations with associated bone loss. ( info) |
10/72. Enhanced fixed prosthetics with a connective tissue ridge augmentation. Augmentation of the partially edentulous ridge can significantly improve the final prosthetic result. The subepithelial connective tissue graft is the treatment of choice to enhance soft tissue contours. The major advantage of the connective tissue graft is the preservation of the existing gingival coloration and tissue characteristics. A case is described that utilizes the subepithelial connective tissue graft for augmentation of a maxillary anterior ridge prior to prosthetic rehabilitation. ( info) |
