Delanian et al. reported the efficacy of pentoxifylline-tocopherol-clodronate (PENTOCLO) treatment for osteoradionecrosis (ORN) of the mandible in 2011. Spontaneous sequestration and epithelialization of the mandibular lesion are induced by this method. We report a case of osteoradionecrosis of the mandible which responded to treatment with PENTOCLO. A 60-year-old man was referred to our department with persistent mandibular ORN after definitive chemoradiotherapy for oropharyngeal carcinoma (T2N0M0). Periodontitis of the right second molar caused ORN, followed by pathological fracture. PENTOCLO treatment was started following 4-week antibiotic therapy. The sequestrum spontaneously separated with mucosal epithelialization two months after the treatment started. The second molar was removed at 11 months because of its increasing mobility. The extraction socket had epithelized and computed tomography (CT) showed that the pathological fracture had healed. No adverse events occurred during this treatment course. PENTOCLO may be an organpreserving treatment option for ORN of the mandible.

A 21-year-old male was shot with a handgun in the mandible, chest, inguinal region, and upper limbs. Upon admission to the emergency room, vital signs were relatively stable.X-ray examination of the head and neck region apparently revealed that the right side of the mandible was fractured and that the bullet-shaped radiopaque object was lodged in the tongue. However, because the radiopaque object in the tongue was found intraoperatively to be a full cast crown on the mandibular firstmolar, the initial clinical impression of the route that the bullet passed through the body proved to be mistaken. The comminuted mandibular fracture was reduced and stabilized with a miniplate under general anesthesia.Five months later, after an abscess appeared in the right submandibular region, the remaining bullet fragments were surgically removed. The postoperative course was uneventful.The unique characteristics of gunshot wounds shoud be carefully considered at initial assessment.

The maxilla has an anatomically complex structure, and therefore recovery of morphology and function is not easily achieved in patients who have lost maxillary bone and surrounding soft tissue due to maxillary cancer. Prosthetic approaches have traditionally been used to treat these defect sites by using jaw dentures to achieve functional recovery. Jaw dentures are a useful means of enhancing intraoral stability by maintaining residual teeth and obturator appliances and of quickly improving chewing, swallowing, and speech functions. Meanwhile, recent advancements in reconstructive surgery have led to the active implementation of closure of defect sites by means of various skin flaps and bony reconstruction of the maxilla using grafts such as vascularized iliac flaps or vascularized fibular flaps. Various debates are ongoing over which criteria should be used to select the maxillary prosthetic treatment and reconstructive surgical method for maxillary defects after tumor resection. Due to their respective advantages and disadvantages, the treatment method should be chosen with consideration for the patient’s general condition and the state of the defects. Depending on the patient, a combination of both prosthetic treatment and reconstructive surgery may be necessary; the advantages of both treatments should be exploited as much as possible. Dental implants have been used in recent years to improve the therapeutic effects of both of these treatments with good outcomes.

We report a pseudoaneurysm that developed after tooth extraction and was treated by transcatheterarterial embolization (TAE). The patient was an 84-year-old woman. Immediately after lower second molar extraction, remarkable swelling developed in the sublingual region. Slightly prolonged bleeding from the second molarregion of the right lower jaw was noted after extraction. The bleeding was controlled by local hemostatic material.On the third day after the extraction, swelling of the sublingual region increased and extended to the floor of themouth. The site corresponding to the wound after extraction showed a pseudoaneurysm on cystographic MRI. Weperformed hemostasis by TAE. The day after TAE, the pseudoaneurysm had disappeared on cystographic CT.The postoperative course was uneventful, without further bleeding.

The initial symptoms of leukemia include oral manifestations such as gingival hemorrhage and swelling. In patients with these symptoms, attention should be paid to the early diagnosis of acute leukemia. This report describes three cases of acute myelogenous leukemia (AML) with initial manifestations in the oral cavity.Patient 1: A 32-year-old woman. Ulcer lesions of the oral mucosa were diagnosed as decubital ulcers, and symptoms did not respond to the application of steroid ointment. She also had appetite loss, general malaise, and bloody stools. Blood examination showed a low white-cell count (1,600/μl).Patient 2: A 52-year-old man. He received anti-inflammatory treatment and had pain at the mandibular third molar region and gingival swelling, but the symptoms did not improve. At the initial visit, pericoronitis of the mandibular third molar with fever and general malaise were observed. Blood examination showed a low white-cell count (2,300/μl) and remarkably increased myeloblasts (20 %) .Patient 3: A 54-year-old woman. She received medication to treat full-mouth gingival swelling. However, fever and general malaise persisted. Blood examination showed a high white-cell count (47,000/μl).All three patients were given a diagnosis of AML on bone marrow biopsy.When the patients present with oral symptoms such as gingival swelling and ulcers accompanied by fever and general malaise, blood examinations should be promptly performed for the differential diagnosis of acute leukemia.

Inferior alveolar nerve and lingual nerve injury is common in the field oral surgery. Nerve injuries are induced by extraction of impacted teeth, and implant impaction, and many cases require surgical nerve repair. Partial amputation injury case and the nerves complete amputation case are adaptation of the nerves surgical repair for severe nervous part equivalent to neurotmesis of the Seddon classification, but when nerves surgical repair is not performed immediately, traumatic neuroma can develop and cause neuropathic pain; accordingly, early diagnosis and treatment are important. The gold standard of nerve surgical repair was nerve end-to-end suturing, and autologous nerve graft. Nerve repair surgery can provide a reasonable result in improving sensation in the inferior alveolar and lingual nerve. More than 80% of patients experienced some improvement in sensation, and dysesthesia did not develop after surgery in any patient who did not have it before surgery. This article will be explained not only surgical therapy but also basic research on peripheral neuropathy to clinical practice.

Patients with jaw deformities frequently have psychological and social problems. There have been many reports on psychological status and satisfaction following orthognathic surgery as determined by quantitative methods. However, only limited information can be obtained by using a quantitative method because the patient’s psychological problems are complex. On the other hand, qualitative studies are suitable for clarifying the hypothetical construction of the phenomenon and patients’ experiences and processes. The purpose of this study was to examine the process by which patient’s psychological and social problems change from pre-treatment to post-treatment. The subjects were 6 female patients who had undergone orthognathic surgery 18 months ago. We conducted semi-structured interviews and performed analysis by a grounded theory approach. The patient’s anxiety started from the period of adolescence and was affected by the patient’s friends. Information on orthognathic surgery gave the patients hope and reduced their anxiety. The processes of psychological and social changes during and after treatment were affected by friends, family, and patients with the same disease. Patients had feelings of accomplishment, happiness, and confidence because they overcame various hardships, and they acquired active attitudes in social life.

We report a case in which an impacted supernumerary tooth migrated from the mandibular ramus to the mandibular coronoid process. A 19-year-old male underwent a panoramic X-ray for orthodontic treatment at the age of 14 years. An opaque region with a well-defined border was seen at the front edge of the right mandibular ramus. Since the right lower third molar was also present, the opaque region was diagnosed as an impacted supernumerary tooth. Imaging examinations, performed every 2 years, showed that the impacted supernumerary tooth gradually moved from the mandibular ramus to the mandibular coronoid process. Thus, the patient visited our department to undergo detailed examinations and treatment. On panoramic X-ray and CT performed at the patient’s first visit to our department, the impacted supernumerary tooth had a total length (root axis) of about 10 mm, the tooth axis was located at the upper end of the right mandibular coronoid process, and part of the tooth was located outside of the tip of the mandibular coronoid process. Under general anesthesia, the impacted supernumerary tooth was extracted. Since the mandibular coronoid process was thin, it was resected during removal of the supernumerary tooth. There was no trismus or mandibular deviation 1 year after the operation.

Carcinoma ex pleomorphic adenoma mainly occurs in the major salivary gland, and a tissue type of myoepithelial carcinoma is extremely rare in the minor salivary gland.<br>We report a case of myoepithelial carcinoma ex pleomorphic adenoma of the hard palate in a 65-year-old man. At presentation, a tumor measuring 23 × 16 mm, which had a painless elastic hard, smooth surface and clear border, was found in the right side of the hard palate. Computed tomographic scanning and magnetic resonance imaging indicated the suspicion of malignancy. Histological examination suggested a myoepithelial carcinoma. A partial maxillectomy combined with a supraomohyoid neck dissection was performed. The histological diagnosis of the resected specimen was a myoepithelial carcinoma ex pleomorphic adenoma. There has been no sign of recurrence as of 2 years postoperatively.

To evaluate the utility of subperiosteal tissue expansion (STE) for mandibular augmentation with hydroxylapatite (HA) particles, two experimental studies in adult mongrel dogs were performed. One was to observe histologic changes following STE and to compare the tissue response to STE with that to subcutaneous expansion. The other was to observe clinical and histologic changes following implantation of HA particles in the subperiosteal expanded bed. In the first experiment, small tissue expanders were placed and inflated subperiosteally in the mandible and subcutaneously in the breast. A fibrous connective tissue capsule was formed surrounding the implanted expanders. Periosteum was replaced by simple connective tissue during expansion. Capsule formation during STE was much more rapid than the subcutaneous expansion. In the subperiosteal group, a thick fibrous capsule consisting of coarse collagen fibers was observed one week after full inflation. Leaving the fully inflated subperiosteal expanders in place more than one month accelerated the resorption of the underlying bone. In the second experiment, one week after full expansion of the mandibular subperiosteal expander, the expander was removed and HA particles were implanted in the expanded bed. Despite marked augmentation with excessive amounts of HA particles, there was no deformity or infection of the grafts, which maintained their designed controur. The firm fibrous capsule formed by STE permitted consolida tion of HA particles easily and effectively, and prevented migration of the particles. Immobilization of the grafts was achieved within two months following implantation of the HA particles.

Bisphosphonates (BPs) are widely used as effective anti-resorptive agents in the treatment of osteoporosis. Although BP-related osteonecrosis of the jaws (BRONJ) is a well-known adverse effect, BP-related oral ulcers are not common. Here we report such a case of BP-related oral ulceration probably caused by an error in how to take the drug. A 91-year-old woman was referred to our department because of oral ulcerations. Her medical history revealed articular rheumatism, dementia, dermatomyositis, and osteoporosis. Clinical examination revealed several ulcerations on the left buccal mucosa, upper lip, soft palate, and tongue. She had been receiving treatment for osteoporosis with alendronate for approximately 10 years and suffered from recurrent oral ulcerations. It was revealed that the patient was inhaling the tablet or placing it in the mouth for an extended period, rather than immediately swallowing the tablet with water. We suspected BPs-related oral ulcerations, so we contacted her prescriber to change the medication. Three weeks after alendronate treatment cessation, the ulcerations had completely epithelialized. In addition, the patient exhibited no clinical evidence of recurrence 4 months after withdrawing alendronate treatment. This outcome confirmed that other forms of treatment may be more suitable for patients who have difficulty in swallowing BP tablets.

The present paper analyzed Chinese medical staff (including stomatologists, pharmacists, and nurses), comprising a total 1782 persons who visited Japan from 1987 through 2006 and were sponsored by the Sasagawa Medical Fellowship. Chinese stomatologists accounted for 88 persons among the total of 1782. Among the 88 stomatologists, 15 were from the 4th Military Medical University, 9 from Jilin University, 8 from Beijing University, and 6 from China Medical University; a total of 25 were from North East China. The departments of Japanese universities attended by Chinese stomatologists included 17 departments of in periodontology and conservative dentistry, 16 departments of oral surgery, 12 departments of prosthetics, 11 departments of orthodontics, and 8 departments of pedodontics at dental and medical schools. Stomatologists who had learned major specialties in Chinese stomatological colleges also majored in similar specialties at the Japanese universities or hospitals.Chinese administrators have been investigating Japanese health science systems, including not only medical technology and clinical medicine, but also several administrative specialties such as medical law, public health, provention of infection diseases, cancer, population research, and budgets from both research and clinical perspectives.Medical staff from central administration in the Government of China have also learned considerably from his or her experience during investigations in Japan. No administration staff of stomatologists were supported by the Sasagawa Fund.

Sixty dentigerous and 10 primordial cysts were examined clinically and pathologically. Fifty-six of the dentigerous cysts had non-keratinizing epithelium and 9 of the dentigerous cysts had keratinizing epithelium. However, 5 keratinizing dentigerous cysts and 1 non-keratinizing primordial cyst were observed as exceptions.Radiographically, the dentigerous cysts were generally of unilocular round shape with a well-defined border. However, the well-defined border was often lost due to severe infection. In contrast, the primordial cysts were more frequently shown to be of irregular and multilocular shape, and the well-defined border was well preserved even with severe infection. Thus, keratinizing epithelium was suggested to be involved in the formation of irregular and multilocular shape and to be more resistant to infection.Pathologically, non-keratinizing epithelium often showed proliferation, a lacy appearance, and ridge elongation in association with inflammatory cell infiltration. In contrast, such changes in keratinizing epithelium were rarely observed even with heavy inflammation. Interestingly, ameloblastoma-like epithelial proliferation and calcification in the absence of inflammation were partially observed in 6 and 7 cases, respectively, independent of keratinization of epithelium. Thus, odontogenic epithelial cells were suggested to have high proliferative and differentiative activities.
