The aim of this study was to clarify the factors which influenced the successful of bony bridging following bone grafts into the alveolar cleft with autogenous particulate cancellous bone harvested from iliac bone.<BR>The bone bridge build up in the alveolar cleft was assessed by periapical radiographs taken before and 18-23 months after the operation. Successful bony bridging defined as a bone bridge with a vertical height of greater than about 11mm, was observed in 123 of all 202 clefts. The frequency of successful bony bridging decreased with increasing severity of cleft type. Successful bony bridging was achieved in 81.8% of unilateral cleft lip and alveolus patients and in only 45.2% of bilateral cleft lip and palate patients. Moreover, the frequency of successful bony bridging was significantly negatively correlated with the width of the cleft. The present study has clearly shown at least two major determinants of successful bony bridging: 1) the cleft type, and 2) the width of the cleft.

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.

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.

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.

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.

Odontogenic keratocyst has been reported by many authors as a specific entity of odontogenic cysts since first described by Philipsen.<BR>Histopathologically, keratinization of the epithelial lining and formation of micro cyst; clinically, higher incidence of recurrence are characterized. Three hundred and sixty odontogenic cysts operated in the Department of Oral Surgery from 1966 to 1984 were studied. A representative histopathologic section from each cyst was screened, using the criteria for odontogenic keratocysts as stated by Pindborg.<BR>Of the 360 cases, 24 fullfilled the histologic criteria for odontogenic keratocysts, for a 6.7 per cent incidence. Of the twenty-four patients, one was diagnosed as basal-cell nervous syndrome, and had five cysts. Of the 24 patients, six had cyst recurrence for a rate of 32 per cent. One patient each had recurrence after one year five months, after three years, after three years four months, after three years five months, after four years six months and one four years ten months after the primary operation. Recently, some investigators have pointed out that odontogenic keratocyst may be benign cystic epithelial neoplasia. In our study, this opinion has been taken into account in view of the higher incidence of recurrence, but no histologically precise feature was obtained.

The tumor extension of T4 cases of upper gum carcinoma (UG-Ca) is clinically similar to T2 cases of maxillary sinus carcinoma (NIS-Ca). However, the prognosis of the former is remarkably unfavorable compared with the latter. A comparative study between 16 cases of UG-Ca (T4) and 14 cases of MS-Ca (T2) was undertaken in order to assess the difference in their prognosis.<BR>The 5 year accumulative survival rate of UG-Ca (T4) was 36.5% and MS-Ca (T2) was 92.3%. While the control rate of the primary lesion after initial therapy, the former was 50% and the latter was 78.6%. As for the rat of cervical metastases noted clinically, it was 75% and 35.7% respectively. Bilateral cervical metastases was noted in 6 cases of UG-Ca (T4) and none in MS-Ca (T2). With respect to the 5 year accumulative survival rate of the cases with pathologically confirmed nodal involvement, it was 0% for UG-Ca (T4) but MS-Ca (T2) was 66.7%.<BR>The unfavorable prognosis for UG-Ca (T4) cases was attributed to failure to control primary and cervical metastases. Therefore, it is necessary to reexamine the margin of the primary resection and the timing for carrying out RND.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with immunologic abnormalities. Although the temporomandibular joint (TMJ) can be involved, early changes of the TMJ affected by RA are unclear, and the treatment for temporomandibular disorders (TMD) in patients with RA is not established yet. Physiotherapy is effective for general joints with RA but its effect for RA of the TMJ is unknown. The clinical effects of physiotherapy for TMD in RA patients was investigated. Five patients with RA visited our department with complaints of the TMD. Physiotherapy, including exercises of TMJ movement and mastication training were stasted, bilaterally and simultaneously. Clinical findings showed an increase in maximal interincisal distance with no pain after therapy in 4 patients. No patient had anterior open bite or TMJ ankylosis in the follow-up period (2.5 to 5.3 years). These results suggest that physiotherapy is also effective for the TMD in RA patients.
