We retrospectively studied of 20 patients who were admitted to the department of cardiovascular internal medicine of our hospital between January 2001 and March 2007 for a diagnosis of infective endocarditis. On blood cultures, oral bacteria were detected in 9 patients. Furthermore, 10 of the 20 patients visited our department. We examined the correlation of dental treatments and oral diseases with infective endocarditis in the 10 patients. The results of the blood cultures suggested correlations of dental treatments or oral diseases with infective endocarditis in 4 patients. Two patients had oral infections, while the other 2 had undergone dental treatment within 2 weeks before the onset of infective endocarditis. Currently, there are two different guidelines (AHA2007 and JCS2008) for the prevention of infective endocarditis. As stated in the JCS2008 guidelines, we believe that, it is necessary to carefully administer prophylactic antibacterial drugs to patients undergoing dental treatments. In addition, we also believe that it is necessary to improve oral hygiene conditions to prevent infective endocarditis associated with dental treatments or oral diseases.

Salivary glands secrete saliva containing fluid, electrolytes and proteins such as amylase and mucin into the oral cavity. Such salivary components are essential for the preservation of oral health. Salivary gland consists of two kinds of cells, acinar and duct cells. In salivary acinar cells, secretion of salivary components is regulated by the autonomic nervous system. When the parasympathetic neurons are stimulated, salivary fluid secretion is provoked via the increase in intracellular Ca2+ concentrations. In the case of stimulation of sympathetic neurons, salivary protein release is induced via the increase in the intracellular messenger cyclic AMP. In this paper, the mechanism of salivary secretion is discussed.

The use of Subcondylotomy procedure, the origin of Intraoral vertical osteotomy (IVRO), has been limited by concerns of potential complications. These concern include condylar position and poor bone contact. Herbert and Nickerson modified the condylotomy procedure by converting it to variation of the IVRO and utilized maxillo-mandibular fixation and rehabilitation to minimize complication. Subsequent reports have confirmed that the IVRO also relieves pain and dysfunction a high percentage of time and, in addition, markedly reduces the complication. Today, IVRO has been using for the correction of Dentofacial Deformity in the world. Because of the primary advantage of this technique compared to the sagittal split osteotomy is the much less frequent and less severe damage to the mandibular nerve. However the protective surgical management was not performed, the potential for bleeding with a vertical oblique osteotomy has been reported to be greater than with the SSRO, because the superior aspect of the osteotomy is carried into the sigmoid notch. I will introduce the safety and ensuring technique of IVRO for correction of dentofacial deformity.

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.

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.

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.

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.

Although varicella zoster virus (VZV) infection commonly occurs in the oral and maxillofacial region, tooth exfoliation and alveolar osteonecrosis are relatively rare complications. We describe two cases of tooth exfoliation and alveolar osteonecrosis caused by VZV infection of the trigeminal nerve and review the literature. A 66-year-old man and a 38-year-old man were referred to our hospital because of tooth exfoliation. The first patient had a history of spinocerebellar degeneration, and the second had a history of chronic myelogenous leukemia. Tooth exfoliation occurred on day 21 and day 25 after the onset of VZV infection, respectively. Clinicopathological examination in the first patient revealed actinomyces infection. Panorama x-ray films obtained previously in the second patient revealed no evidence of severe periodontal disease before VZV infection. These findings suggested that tooth exfoliation and osteonecrosis by VZV infection were not only caused by existing severe dental infectious disease, but also by various factors such as multiple oral bacteria, tissue reaction to VZV infection, and compromised status.

We encountered a rare case of actinomycosis in the maxillary sinus secondary to an iatrogenic foreign body.A 32-year-old man was referred to our hospital for evaluation and treatment of nasal obstruction. The clinical diagnosis was odontogenic maxillary sinuitis. Under general anesthesia, a radical sinusotomy of the right maxillary sinus and apicoectomy of the right maxillary second premolar were performed. We found necrotic tissue and an iatrogenic foreign body with sulfur granules at the bottom of the maxillary sinus. Histopathological examination revealed the presence of actinomyces. The histopathological diagnosis was actinomycosis.The postoperative course has been uneventful as of 20 months after operation.

In the oral region, traumatic neuroma is rarely encountered in daily clinical practice. As this lesion is caused by some kinds of trauma, traumatic neuroma may develop after operations such as tooth extraction. Traumatic neuroma appears to be a tumors, however, pathologically it is not thought to be a neoplasm, but nodular hyperplasia in nerve fibers. A typical case of traumatic neuroma is presented. A 32-year-old woman with a nodule arising in the left mental foramen region was referred to us. The nodule was first noted 6 years ago and persisted without any change until treatment. Before the nodule had appeared, the patient underwent surgical removal of a mucocele from the left mental foramen at another hospital. After the operation, the same region underwent surgery twice because of recurrence. The nodule was slightly tender, covered with normal mucosa, and red-bean size at presentation. A traumatic neuroma was diagnosed clinically. The tumor was removed under local anesthesia and examined histopathologically. Numerous distinct neural bundles with densely fibrous connective tissue were observed histopathologically in the specimen. The histopathological diagnosis of traumatic neuroma was established. No signs of recurrence have occurred so far.

This report describes occlusal reconstruction in a 23-year-old man with cleidocranial dysplasia (CCD).It is often difficult to perform dental treatment in patients with CCD because of complicated skeletal and alveolarabnormalities. First, endosseous implants were used to restore the mandibular molar region. After careful examinations, Le fort I type osteotomy was performed with distraction osteogenesis to advance the maxilla.Subsequently, implants were used to restore the maxillary arches with a fixed prosthesis. After the provisionalrestoration, the final prosthesis was set. The most recent follow-up, 1 year after the final treatment, confirmed asatisfactory treatment result.

Paraquat-diquat products are used as herbicicides, but are toxic to humans, even in small amounts.These products mainly damage the lungs, liver, and kidneys. To treat intoxication resulting from ingestion of paraquat-diquat products, gastric lavage, intestinal lavage, forced diuresis, and blood purification are generally performed, or a laxative or an adsorbent may be used. However the associated mortality rate is approximately 70 %. A 51-year-old woman put a paraquat-diquat product accidentally into her mouth, but immediately spit it out. Spontaneous pain developed in the oral cavity after 2 days, and she visited our hospital 4 days later with this pain as the chief complaint. Erosive lesions had developed from the oral cavity to the pharynx, and the patient had severe haphalgesia and odynophagia. The patient was given a diagnosis of oral chemical injury and was immediately hospitalized to control the pain and monitor general condition. Blood examinations revealed acute renal failure. Four sessions of hemodialysis were performed. The patient's general health status improved, and the pain in the oral cavity subsided. She was discharged after 17 days.
