Injury by a bear attack mostly occurs in the head and neck region and can be fatal, requiring immediate treatment. In addition to first-aid treatment, preventive measures against infectious and parasitic diseases are also necessary. We report two cases of multiple facial lacerations caused by the same black bear. Patient 1: A 51-yearold woman was attacked by a black bear while trekking and sustained multiple facial lacerations. She was successfully treated under general anesthesia 3 hours after the injury. Patient 2: A 65-year-old man was attacked by the same black bear when he tried to rescue the woman and sustained multiple facial lacerations as well. He was also successfully treated under general anesthesia 5 hours after injury. The clinical course of both patients was uneventful with no infection or sensory or motor nerve dysfunction.

According to the classification of the World Health Organization (WHO), primary intraosseous carcinoma (central carcinoma) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium.We report a case of central carcinoma occurring in a 69-year-old man. Marsupialization was performed under the diagnosis of residual radicular cyst.Histopathological examination revealed a moderately differentiated squamous cell carcinoma with atypical lining epithelium. A combination of radiation and chemotherapy was given, followed by a partial maxillectomy. Unilateral total neck dissection was performed 3 months after the initial operation. Five years later, the patient has been free of recurrence and distant metastasis.

Sweet’s Syndrome is a disease characterized by multiple nodules or edematous erythema elevatum of the face, neck, and skin, accompanied by acute fever and peripheral leukocytosis. This disease is considered one of the paraneoplastic syndromes of blood tumors. A 50-year-old Japanese man was referred to our department because of oral mucosa hyperplasia. The patient who had the various condition and we performed various examination, but needed long time for definitive diagnosis. In this article, we report a case of oral mucosa hyperplasia caused by Sweet’s Syndrome that was difficult to diagnose.

Regarding the open surgery of temporomandibular joint mobilization for the removal of adhesive pseudwalls assisted by arthroscopy, this summary explained the surgical approach by Al-Kayat and Bramley, anatomically important points to remember, indications and treatment results, and procedures and the importance of postoperative rehabilitation.This introduced the diagnostic procedures and treatment algorithm for temporomandibular joint disorders (types IIIb and IV) patients with severe mouth-opening disturbance (mouth-opening distance was less than 30 mm) in the Second Department of Oral and Maxillofacial Surgery, Osaka DentalUniversity. Furthermore, regarding intractable cases whose disease period was more than 6 months and adhesion lesions in the temporomandibular joint were suspected, we evaluated the clinical significance of the open surgery of temporomandibular joint mobilization for the removal of adhesive pseudwalls assisted by arthroscopy as a salvage operation.

Loxonin® is one of the non-steroidal anti-inflammatory analgesics of the phenylpropionic acid group. It is known that its side effects on digestive organs are less than those of other analgesics because of “prodrug” A clinical evaluation of Loxonin® on pain controlafter minor oral surgery is here reported in regard to time course of effectiveness, side effects, its availability and related points reflect, c1 in pain control.The number of test cases was 233 comprising 178 cases with single dose (120mg) only at pain onset and 55 cases with 3-divided doses (total 180mg). Of them, 23 cases were omitted because of no Loxonin® without postcperative pains.The benefit of the pain control method in the former cases reached 94.4% and the latter showed 96. 0%. The final availability was certainly more than 90% regardless of surgical treatments and inflammation degree before operation.From the results, it turned out Loxonin® was safe in the clinical use and highly effective in the pain control following minor oral surgery.

We report a rare case of rhinogenous optic neuritis(RON)that was induced by odontogenic maxillarysinusitis in a 34-year-old woman. The patient was referred to our hospital because of visual disturbance of the left eye, gradually developing over the course of 1 month. On presentation to the Department of Ophthalmology, the corrected visual acuity and central critical flicker frequency of the affected left eye was 1.0 and 24Hz, respectively (1.2 and 45 Hz for the right eye). The left eye also showed paracentral scotoma. Computed tomography and magnetic resonance imaging revealed left sphenoid and maxillary sinus opacification, which indicated thickening of these sinus membranes. For a clinical diagnosis of RON in the left eye, a otolaryngologist performed endonasalsphenoid and maxillary sinusotomy under general anesthesia. After sinusotomy the patient came to our department for further evaluation. A panoramic radiograph showed projection of root canal filling material to the left maxillary sinus from the apex of the left maxillary second premolar. We extracted this tooth and the projecting material. Visual symptoms completely resolved 3 months after diagnosis by collaboration among the patient’s ophthalmologist, otolaryngologist, and oral and maxillofacial surgeon.

Bisphosphonates are used for the management of bone metastatic disease and hypercalcemia caused by malignancy, as well as the treatment of osteoporosis. Recently, a number of patients with bisphosphonate-associated osteomyelitis and osteonecrosis of the jaws have been reported in the English-language literature. This report describes patients with bisphosphonate-related osteomyelitis and osteonecrosis of the jaws in Japan. The subjects were enrolled using questionnaires sent to 239 institutions certified as training facilities by the Japanese Society of Oral and Maxillofacial Surgeons in 2006. Thirty patients (4 men and 26 women) from 18 different institutions (mean age at diagnosis, 66.9 years) were studied. As for local features, pain with or without swelling was the most common symptom and sign. The mandible was affected in 22 patients, the maxilla in 6, and both jaws in 2. Twenty patients received intravenous bisphosphonates, 8 received only oral bisphosphonates, and 1 received both types of treatment. The reasons for bisphosphonate treatment were bone metastasis from breast carcinoma (13 patients), multiple myelomas (6 patients), osteoporosis (8 patients), and hypercalcemia related to malignancy. More than 50 % of the patients underwent oral surgery including tooth extraction just before or during treatment with bisphosphonates, while 5 patients received no dental treatment. In addition to antibiotic therapy, surgery, including sequestrectomy and curettage, was performed. As for outcome, 8 of the patients were completely cured, while 17 patients remained under treatment at the time of this writing.

Arsenic trioxide used to be used as an effective endodontic treatment. However, domestic production of arsenic trioxide for mortal pulpectomy was discontinued in 2005, because it is a toxic agent that has the risk of injuring periodontal tissues. We report a case of mandibular osteonecrosis caused by leakage of arsenic trioxide in a child after 2005. The patient was a 6-year-old boy who presented with swelling of the right buccal region, after arsenic trioxide had been used for mortal pulpectomy in the mandibular right second primary molar. The condition was diagnosed as mandibular osteonecrosis. The mandibular right first primary molar and mandibular right second permanent premolar were extracted, and a sequestrectomy was performed with the patient under local anesthesia. We still should consider that leakage of pulp devitalizing agents can cause osteonecrosis.

Cancer occuring in the dorsum of the tongue is very rare. Several reports indicate that the rate of cancer occurrence in the dorsal tongue ranges from 2.8% to 7.2 % of all tongue cancer.<BR>In our clinic, there has been only one case of dorsal tongue cancer among 89 cases of tongue cancer from 1979 to 1992.<BR>The patient was a 68-year-old male who visited our clinic with a chief complaint of a tumor mass in the left dorsum of the tongue in November 1983.<BR>The tumor was a round, circumscribed, raised, and centrally depressed mass with a red surface. It was 15 mm in diameter and elastic but firm in consistency.<BR>Macroscopically, the tumor was doughnut-shaped.<BR>Pathologically, the tumor was diagnosed to be a squamous cell carcinoma.<BR>He was treated by intraoral electron therapy, one time (10 Gy) per week. The total dose amounted to 40 Gy. Clinically and pathologically, the tumor disappeared at that time.<BR>Nine years after intraoral electron therapy, he is still alive without primary recurrence or distant metastasis.

Although mouthguards are used to protect the stomatognathic region in contact sports, their biomechanical efficacy has not been proved. The finite element method (FEM) is widely used in biomechanical studies involving static stress analyses. Studies of mouthguards especially require dynamic analyses. We performed an impact analysis of the maxillofacial region with the use of a pseudo 3 -D FEM model consisting of the head and neck in order to verify the efficacy of two mouthguard models against impact on the chin.The effects of impact on the maxillary central incisors and the neck of the condyle increased remarkably when the mouth was open. With the use of a mouthguard, the efficacy of impact absorption extended to the maxillary central incisors and the lateral margin of the aperture. A soft-type mouthguard was more effective than a hard-type one. With the use of a mouthguard, stress was concentrated at the neck of the condyle. The use of a mouthguard decreased stress to regions adjacent to the cerebrospinal area. These results suggest that mouthguards are effective in preventing brain concussion.

Thermotherapy by 2450 MHz microwaves was performed on oral cancer patients and its effectiveness was analyzed and evaluated.Subjects were 7 primary oral cancer patients (4 lower gum cancer, 2 buccal mucosa and 1 oral floor) and 5 recurrent cancer patients (3 with cheek lesion and 2 with neck lesion). Heat was generated by a microwave apparatus of 2450 MHz.Seven cases which received intraoral thermotherapy on primary lesions were treated in combination with radiation and bleomycin. Thermotherapy was performed twice a week, up to 5-8 times in total, applyied immediately after the radiation therapy. Intraoral applicator was a flexible leakage-type coaxial applicator 2-4 mm in diameter and 40-90 mm in length. It was modified depending on each tumor size and shape. Tumor surface was heated to 42-45°C for 30-50 minutes and the heat distribution pattern of each modified applicator was checked using Phantom Model. Of the seven lesions, 6 (85.7%) showed complete regression (CR) and one showed partial regression (PR). Histological examination was made on five cases which received surgical tumor resection. Among them, one was grade III and the rest were grade IIb by Simosato's criteria. Tumor necrosis and mucosal reaction were seen at the heated site from the early stage of treatment and the thermotherapy was obviously effective.Five recurrent cancer patients received extraoral thermotherapy without radiotherapy on the cheek or neck lesions using the non-contact type applicator. Tumor necrosis was limited to the surface area and the regression effect was minimum which might be due to the lack of combination therapy of radiation.Thermotherapy seemed effective for the oral cancer when used in combination with radiation. However, more clinical experience is needed to evaluate the usefullness of this treatment.

A case of non-clostridial gas gangrene with sepsis in the maxillofacial region and neck caused byodontogenic infection is reported.A 74-year-old woman consulted our department because of painful swellingof the head and neck region.She had been treated for depression for about 20 years.Her general conditionwas classified as I-2 coma according to the Japan coma scale.Blood examination revealedleukocytosis, hepatopathy, nephropathy, hypoalbuminemia, and hyperglycemia.A computed tomographicscan showed gas accumulation with abscess formation in the temporal, buccal, submandibular, and cervicalregions.Administration of antibiotics (PAPM/BP) and gamma-globulin was followed by emergencysurgical drainage under general anesthesia. Microbiological examinations revealed Streptococcus pneumoniae in the abscess and Peptococcus asaccharolyticus in venous blood on the 1st disease day. Aftertreatment, the swelling disappeared and the results of blood tests became normal.However, a secondmicrobiological examination of venous blood also revealed Peptococcus asaccharolyticus on the 9 th diseaseday. Antibiotics (CLDM) were given from the 17th to 20th disease days.Hyperglycemia was controlledby insulin.She was discharged on the 53rd disease day.Rapid diagnosis by computed tomography, rapid surgical drainage, appropriate chemotherapy, and examinationsof blood cultures and for DIC are required to save patients'lives.

We studied the cause, status, and treatment of temporomandibular joint (TMJ) dislocation in patients with psychic and cerebral diseases. These diseases were present in 11 (26.2 %) of 42 patients with TMJ dislocation. Psychic disease included 2 cases of mental retardation and 3 of schizophrenia. Cerebral diseases included 1 case of cerebral infarction, 3 of cerebral hemorrhage, 1 of epilepsy, and 1 of Parkinson disease. There were many old patients among those with cerebral diseases. Convulsions characteristically led to TMJ dislocation. There was prolonged dislocation of the TMJ. A reliable treatment was required in patients with these diseases. Therefore, augmentation of the articular tubercle was indicated. It was suggested that incoordination of the masticatory muscles induced TMJ dislocation. Furthermore, extrapyramidal disorders may have been caused by antipsychotic drugs, Parkinson disease, and cerebrovascular disease; convulsions due to epilepsy may lso have been involved.
