1/10. Use of third molar transplantation for closure of the oroantral communication after tooth extraction: a report of 2 cases.

    OBJECTIVE: This clinical report introduces a promising and unique method for the immediate closure of the oroantral communication (OAC) after tooth extraction: the use of the transplanted third molar with closed apices. STUDY DESIGN: In 2 adult patients, OAC caused by the extraction of an upper molar was immediately closed by using a transplanted third molar with complete root formation. After tooth extraction at the recipient site, OAC with perforated mucosa of the sinus floor was confirmed and the donor third molar was transferred to the prepared recipient socket. Endodontic therapy of the transplanted third molar began at 3 weeks after surgery, and prosthetic treatment was completed at 5 months after the operation. These 2 patients were carefully observed both clinically and radiographically. RESULTS: Closure of the OAC was successfully performed, and the transplanted teeth became fixed with the passage of time in these 2 patients. root resorption did not occur, and good functional results were obtained without any complications. CONCLUSIONS: Tooth transplantation of a mature third molar for closure of the OAC is a simple and excellent method because the transplanted tooth not only closes the communication to the maxillary sinus, but it also satisfactorily functions at the recipient site during mastication, even in adult patients.

2/10. An unusual giant cell lesion in a child with vitamin d-resistant rickets.

    This paper reports the presence of a focus of giant cells in a sinus tract associated with an abscessed primary tooth in a patient with vitamin d-resistant rickets. The relevance of this giant cell lesion to the systemic disorder is discussed.

3/10. An iatrogenic foreign body (dental bur) in the maxillary antrum: a report of two cases.

    Two cases of foreign bodies of the antrum are reported. One was a turbine bur which presumably entered through an oro-antral fistula after a tooth extraction. The other was also a turbine bur where the mode of entry was not clear (lack of oro-antral fistula), but it presumably entered through the socket of the extracted tooth. The mucosa of the antrum appeared normal in spite of the lengthy presence of the foreign body.

4/10. Ectopic eruption of a maxillary third molar tooth in the maxillary sinus: a case report.

    Ectopic eruption of teeth into regions other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin, and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar tooth that caused chronic sinusitis in the maxillary sinus.

5/10. Orbital abscess: visual loss following extraction of a tooth--case report.

    OBJECTIVE: It is the purpose of this article to alert the general practitioner to the severe consequences that may result from a tooth extraction, including the loss of vision, despite the use of antibiotics. CONCLUSIONS: Early and aggressive treatment is critical in obstructing the spread of infection toward the orbits, the eyes, and eventually the brain.

6/10. maxillary sinusitis and periapical abscess following periodontal therapy: a case report using three-dimensional evaluation.

    BACKGROUND: maxillary sinusitis may develop from the extension of periodontal disease. In this case, reconstructed three-dimensional images from multidetector spiral computed tomographs were helpful in evaluating periodontal bony defects and their relationship with the maxillary sinus. methods: A 42-year-old woman in good general health presented with a chronic deep periodontal pocket on the palatal and interproximal aspects of tooth #14. Probing depths of the tooth ranged from 2 to 9 mm, and it exhibited a Class 1 mobility. Radiographs revealed a close relationship between the root apex and the maxillary sinus. The patient's periodontal diagnosis was localized severe chronic periodontitis. Treatment of the tooth consisted of cause-related therapy, surgical exploration, and bone grafting. A very deep circumferential bony defect at the palatal root of tooth #14 was noted during surgery. After the operation, the wound healed without incidence, but 10 days later, a maxillary sinusitis and periapical abscess developed. To control the infection, an evaluation of sinus and alveolus using computed tomographs was performed, systemic antibiotics were prescribed, and endodontic treatment was initiated. RESULTS: Two weeks after surgical treatment, the infection was relieved with the help of antibiotics and endodontic treatment. Bilateral bony communications between the maxillary sinus and periodontal bony defect of maxillary first molars were shown on three-dimensional computed tomographs. The digitally reconstructed images added valuable information for evaluating the periodontal defects. CONCLUSION: Three-dimensional images from spiral computed tomographs (CT) aided in evaluating and treating the close relationship between maxillary sinus disease and adjacent periodontal defects.

7/10. An enigmatic sinus tract origin.

    diagnosis of the origin of a sinus tract is very complex. In this case report, a sinus tract stoma appeared above the left maxillary incisor, but the causative tooth was the right maxillary incisor. Incorrect diagnosis led to endodontic treatment of a healthy tooth followed by apicoectomy, which was also ineffective. An endodontic consultation revealed the true origin of the sinus tract. Five days after completing conservative endodontic treatment of the right maxillary incisor, the sinus tract disappeared. This case confirms the need to include a diagnostic tracing radiograph as part of routine diagnostic procedures.

8/10. Alveolar bone necrosis and tooth loss. a rare complication associated with herpes zoster infection of the fifth cranial nerve.

    Eleven case reports involving herpes zoster infection associated with alveolar bone necrosis and tooth loss were reviewed in order to develop a patient profile for this rare combination of physical findings. The clinical course of a 56-year-old white woman with herpes zoster infection of the fifth cranial nerve and related alveolar bone necrosis, tooth loss, and oroantral fistula development is reported. The etiology and management of herpes zoster infection associated with destructive oral sequelae are discussed.

9/10. Application of Ca-beta-glycerophosphate for artificial apical barrier formation.

    This case demonstrates an artificial apical barrier formation by using calcium-beta-glycerophosphate paste in a nonvital permanent tooth with an open apex communicating with the maxillary sinus. The long-term satisfactory outcome of this case depended on the resolution of periapical pathosis and root canal obturation without overextension.

10/10. Sinus obliteration for chronic oro-antral fistula: a case report.

    This report describes a patient with chronic oro-antral fistula resulting from tooth extraction. Several local flap procedures failed to close the fistula, which was complicated by chronic sinusitis. Ultimately, cure was achieved via antral obliteration using vascularised temporoparietal fascia, sparing remaining maxillary alveolar bone. Total, trans-buccal maxillary sinus obliteration with fascia should be considered for the treatment of oro-antral communications refractory to treatment with intraoral tissues.
