Bone grafts are useful for the placement of implants in atrophic bone in edentulous regions. Usually, grafted bone undergoes resorption and provides inadequate support for implants. The guided bone regeneration (GBR) method can prevent resorption of grafted bone; however, GBR has some disadvantages, including exposure of the membrane and infection. Platelet rich plasma (PRP) accelerates wound healing by autologous growth factors. We consider growth factors of PRP to promote sufficient bone for implants. In this study, we used PRP gel to graft, bone harvested from the chin to the anterior maxillary region, which had undergone resorption. After 14 weeks, we decided that there was sufficient bone in the region on computed tomographic examination. After 16 weeks, implants were able to be placed, despite bone resorption. Biopsy of bone specimens revealed active osteogenesis and bone remodeling. Our results suggest that PRP could accelerate bone healing and remodeling, but could not prevent bone resorption in a similar manner to GBR. We confirmed that PRP gel is beneficial at the time of bone grafting for implants.

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.

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.

We present a case of large complex odontoma of the mandible of an 8-year-old female that showed interesting radiographic features and remarkable radioisotope uptake.<BR>The patient visited our hospital with a complaint of delayed eruption of the left mandibular first molar. Radiographic features showed a large radioopaque lesion of the left mandibular body. The tumor was successfully removed by surgical procedure and the mandibular base of the mandible and the mandibular canal were preserved without any functional disorder.<BR>The histopathological specimens suggested that maturing process of odontogenesis was occurring.<BR>We have regarded this case as an immature odontoma or developing odontoma of early stage and discussed the considerations of the clinical diagnosis, radiographic features, histopathological findings and the relationship between the usual odontoma and the other odontogenic tumors such as ameloblastic fibroma or ameloblastic fibro-odontoma and so on.

We clinicostatistically studied 102 cases of external dental fistula at the Department of Oral and Maxillofacial Surgery, Asahikawa Medical College during the past 18 years (from 1977 through 1994). The following results were obtained:<BR>1) The 102 patients comprised 49 males and 53 females. As for age, patients, in their twenties and thirties were most frequently encountered.<BR>2) The period from the onset of disease until the first visit at our clinic tended to be relatively long. The longest period was 13 years and the shortest several days. The average period was 16.9 months.<BR>3) The cheek area (48.0%) was the commonest site of external dental fistulae.<BR>4) External dental fistula arose more often in the mandibular region than the maxillary region, and was especially frequent in the mandibular molars and incisors.<BR>5) In many patients the involved teeth and the fistula were concurrently treated by surgery.

The presence of sebaceous glands in the oral mucosa is not uncommon, however, sebaceous elements are rarely found on the tongue. Only six cases of ectopic sebaceous glands of the tongue have been reported previously. And four cases of them which have formed duct-like structure were discussed in relation to the thyloglossal duct.<BR>We have recently encountered a case which was clinically and microscopically similar to the prior cases. In this article, a case report was presented with the review of the literature.

<I>Salmonella</I> enteritidis (<I>S</I>. enteritidis) often causes bacterial food poisoning. However, infection, with the exception of gastroenteritis, caused by <I>S</I>. enteritidis is very rare. This report describes a case of submandibular abscess caused by <I>S</I>. enteritidis, which we encountered recently. We believe that this is the first reported case of <I>S</I>. enteritidis infection in the oral and maxillofacial region.<BR>A 42-year-old man visited our hospital because of right submandibular swelling after the extraction of his right wisdom tooth. His general condition was good, except that he had discontinued treatment for diabetes mellitus. Surgical drainage was perfomed, and <I>S</I>. enteritidis was detected from the pus but not from feces. Therefore, he was given tosufloxacin for 2 weeks.<BR>The route of infection in this case was thought to be poisoned food. Furthermore, <I>S</I>. enteritidis directly invaded an extracted dental socket.

Angioedema is sudden local swelling of the lips, eyelids, buccal region and tongue. It is usually induced by drugs. Angioedema is a well-recognized side effect of angiotensin-converting enzyme inhibitors (ACEs), but angioedema associated angiotensin II receptors blockers (ARBs) is very rare. We report a case of angioedema of the tongue and floor of the mouth that was probably induced by an ARB.A 76-year-old man came to our emergency unit because of acute swelling of the tongue and difficulty breathing.He had a medical history of hypertension and cerebral infarction, but no allergic disease. He had severe diffuse edematous swelling of the submandibular and cervical regions, an elevated tongue making it difficult to close his mouth, and sialorrhea.Although urgent computed tomography showed marked swelling of the tongue, there was no evidence of edema in the respiratory tract. Angioedema of the tongue was diagnosed, and hydrocortisone sodium succinate was given intravenously. Within 12 hours the swelling of the tongue and floor of the mouth resolved completely.Candesartan was strongly suspected to have caused the angioedema, and we discontinued it. There has been no evidence of recurrence of the angioedema during the 18 months since candesartan was discontinued.

Total RNA extracted from human temporomandibular joint (TMJ) discs of patients with temporomandibular disorders (TMD) were examined by RT-PCR. The expressions of decorin, biglycan and aggrecan mRNA in the disc were demonstrated. These results suggest that human TMJ discs of patients with TMD contain decorin and biglycan. The expression of aggrecan mRNA was confirmed in calcified disc tissue.

To assess the malignant potential of tongue cancer by intraoral ultrasonography, we examined 22 patients with squamous cell carcinoma of the tongue. Ultrasongraphic findings of the lesions were evaluated with respect to shape, border, internal echo, marginal echo, and depth of invasion (usD). Except for 3 tumors with a pathologic depth of invasion (pD) of less than 1 mm, 19 of 22 tumors (86.4%) were detected as hypoechoic lesions on intraoral ultrasonography. When the ultrasonographic and clinicopathologic findings were compared, tumors with diffuse invasion exhibited irregular shapes and diffuse borders on ultrasonography. Tumors with neck metastasis showed irregular shapes, diffuse borders, and hyperechoic marginal echoes. In addition, there was a significant correlation between usD and pD. Seven (58.3%) of 12 tumors with invasion of 8.0mm or more on ultrasonography were associated with neck metastasis.<BR>In conclusion, intraoral ultrasonographic examination of tongue cancer provides information useful in evaluating tumor extent and malignant potential.

Children often play with foreign objects such as a toothbrush in their mouths and sustain intraoral lacerations. Rarely, the objects penetrate into the parapharyngeal space and have to be surgically removed in cooperation with other specialties. We report a case of an intraoral penetration injury caused by a toothbrush entering the parapharyngeal space. A 2-year-old girl who was brushing her teeth before bedtime was intraorally impaled with a toothbrush after falling from an indoor jungle gym for infants. The patient was transferred to the emergency room in our hospital. CT scanning showed the toothbrush head near the internal carotid artery in the parapharyngeal space. Antibiotics were intravenously administered, and the foreign body was removed under general anesthesia, followed by wound suturing. The patient was discharged on the 7 day without any complications such as post-traumatic thrombosis of the internal carotid artery or deep neck abscess. It is important to adequately educate parents and their children about the dangers of a toothbrush as a foreign body that can cause serious penetration injuries.

We studied soft tissue injuries of the oral cavity caused by a toothbrush in 59 children younger than 7 years from 1983 through 2003. There were 35 boys and 24 girls aged 9 months to 6 years 7 months, with a peak incidence at 1 year. Falling down was the cause of injuries in 46 children. Forty-one children visited us directly, whereas others were referred to us by surgeons, emergency specialists, dentists, otolaryngologists, and others. Thirty-one children presented within 3 hours after injury and 15 the following day. The soft palate and palatoglossal arch, buccal mucosa, hard palate, oral floor, retromolar region, upper lip, gingiva, and tongue were involved in 25, 20, 6, 3, 2, 1, 1 and 1 child, respectively. Lacerations greater and less than 10 mm long were seen in 20 and 16 hildren, respectively. Submucous bleeding was present in 13 children, and scratches were present in 10 children. In 3 children, the wound was associated with herniation of the buccal fat pad. The wound was sutured and antibiotics were given to 23 children. Twenty children were observed without antibiotic treatment, and 16 children were given antibiotics. Local infection occurred in 3 children.

Major salivary glands, parotid, submandibular and sublingual glands, secrete serous and mucous saliva via the proper excretory ducts connecting between oral cavity and glandular bodies. Discovery of the salivary ducts in 17th century established the concept of exocrine secretion as well as salivary glands. In more recent investigations have revealed the endocrine functions of salivary glands by a variety of cell growth factors produced by granular ducts. In the present review describes the macroscopic findings of human major salivary glands and the microscopic differences of human and rodent salivary glands.

We examined 13 cases of primary oral aspergillosis in adult leukemia patients.Although the patients received systemic and local antifungal treatment in laminar air-flow rooms, primary oral aspergillosis generally developed in about 20 days in association with adrop in leukocyte count to under 1, 000/mm3 after chemotherapy. The initially involved area was the marginal gingiva which was associated with necrosis and severe pain. At the same time, spiking fever of about 39°C was observed. Necrotic changes of the gingiva progressed rapidly and invasively extended from the mucosa to muscle and bone. Local aspergillosis basically disappeared when the hematologic status of the patients returned to normal levels under antifungal treatment. The prognosis of primary oral aspergillosis was relatively good. However, damaged oral tissues were easily reinfected with aspergillus during chemotherapy.These findings suggest that oral hygiene plays an important role in the development of oral aspergillosis in adult leukemia patients.
