1/5. Management of arsenic trioxide necrosis in the maxilla.Historically, pulp-necrotizing agents were commonly used in endodontic treatments. They act quickly and devitalize the pulp within a few days. However, they are cytotoxic to gingiva and bone. If such an agent diffuses out of the cavity, it can readily cause widespread necrosis of gingiva and bone, which can lead to osteomyelitis of the jaws. Although the use of arsenic trioxide can cause severe damage to surrounding tissues, producing complications, it is still used in certain areas in the world. This article presents and discusses two cases of tissue necrosis and their surgical management. These cases showed severe alveolar bone loss in the maxilla, which affected the patients' quality of life and limited the restorative possibilities. As dentists, we should be aware of the hazardous effects of arsenic trioxide and should abandon its use. Because of its cytotoxicity, there is no justification for the use of arsenic trioxide in the modern dental practice.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/5. 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.- - - - - - - - - - ranking = 34.323583015542keywords = oral cavity, cavity (Clic here for more details about this article) |
3/5. Herniation of the antral membrane through an extraction site. Report of a case.A case of herniation of the antral membrane through a recent extraction site is presented. The lesion was initially diagnosed as a tumor by the referring dentist. Oroantral fistulas are not an uncommon finding after dental extractions. It is rare, however, to see herniation of the antral membrane with large polyps extending through the fistula into the oral cavity. A search of the literature revealed only two other such cases. Surgical removal of the polyps and closure of the oroantral fistula by means of a buccal sliding flap technique is discussed.- - - - - - - - - - ranking = 34.323583015542keywords = oral cavity, cavity (Clic here for more details about this article) |
4/5. A new approach for repair of oro-antral-nasal fistulae. The anteriorly based buccinator myomucosal island flap.Oral-antral-nasal fistula (OAN) is a commonly encountered clinical problem. The literature is filled with a plethora of methods described for closing a persistent OAN. Local flaps are available to close minor to moderate defects, however, large fistulae can be a very challenging reconstructive problem. Various areas of the oral cavity have been used for closure of OAN. We describe a technique to reconstruct the oral cavity, in this case an OAN. The anteriorly based buccinator myomuosal island pedicle flap (BMIP) provides an alternative method for reconstructing the oral cavity. An extensive review of the literature as well as the anatomy of the buccinator, its reconstructive capabilities, and two case reports are included.- - - - - - - - - - ranking = 102.97074904663keywords = oral cavity, cavity (Clic here for more details about this article) |
5/5. Pedicle tongue flap for closure of an oroantral defect after partial maxillectomy.The position, size, and composition of the tongue make it ideal as a potential donor site for repair of certain oral defects. Adherence to principles of sound flap design must be followed. A technique for closure of large oroantral communications with use of a pedicled graft from the lateral border of the tongue has been described. This procedure provides the patient with immediate repair of the defect, while maintaining the relatively normal anatomic architecture of the oral cavity. We believe that this technique is also applicable to closure of other types of oroantral defects in addition to those described.- - - - - - - - - - ranking = 34.323583015542keywords = oral cavity, cavity (Clic here for more details about this article) |
