    The solubility of tricalcium phosphate was studied in lactate Ringer solution at 37°C (for 5 min to 7 hours) based on thermodynamic analysis of the solution. The analysis suggested that thermodinamically most stable phase of hydroxyapatite forms as a result of tricalcium phosphate dissolution. Although X-ray diffraction of the solid showed no hydroxyapatite at standard gain, transmission electron microgram showed new solids with morphology quite different from that of tricalcium phosphate introduced into the lactate Ringer solution.

    A human oral cancer/nude mice system has been established for an anticancer agent screening system, which is expected to have higher predictability of clinical effect. In this preliminary report, the method of successive transplantation of human cancer in nude mice and the histological characteristics of the tumor were reported.
    1) 8-to 10-week-old male BALB/cA-nu mice kept in vinyl isolater were used.
    2) Human cancer in this experiment was derived from an oral floor tumor histologically diagnosed as squamous cell carcinoma in a 58-year-old man.
    3) The tumor tissue which was minced in sterilized penicilline-streptomycin PBS (-) solution (PC: 100 u/ml, SM: 100γ/ml) was sectioned in small pieces approximately 1mm 3 in volume. 2 to 3 pieces were injected into subcutaneous tissue of the back of each animal.
    4) After the fifth generation of serial transplantation, the tumors became stable, showed stable growth curves and maintained the histological features of moderately differentiated squamous cell carcinomas.

    In Le Fort type I osteotomy, separation of the pterygomaxillary suture is. dangerous process which must be carried out during the surgical procedure. Fittness of osteotomes best suited for safe separation of the pterygomaxillary suture was studied by measuring the strain distribution over surrounding bone structure and examining the direction of the fracture line. The following results were obtained:
    1) Measurement of the static strain revealed that the strain exerted on the medial and lateral plates of the pterygoid process can be reduced when the suture is initially separated with an Obwegeser's osteotome and finally with a swan's neck osteotome.
    2) Application of a straight osteotome at different angles indicated that a straight osteotome wedged into the posterior aspect of the pterygomaxillary suture at 30 degrees to the sagittal plane from reduces the static strain exerted on the medial and lateral plates of the pterygoid process.
    3) Measurement of the dynamic strain during the rupture of the pterygomaxillary suture revealed that separation of the suture initially as well as finally with a swan's neck osteotome reduces the strain exerted on the medial and lateral plates of the pterygoid process. This finding suggests that this osteotome enables safe separation of the suture.
    4) Fracture of the pterygoid process during the separation of the pterygomaxillary suture showed two fracture patterns, a horizontal fracture of the upper part and also a horizontal fracture of the lower one.
    5) In every experiment, after separation of the unilateral pterygomaxillary suture, strain increased at almost every measuring point, therefore final separation of pterygomaxillary suture is a more dangerous phase of the procedure than initial separation.
    6) In separation of the suture with an Obwegeser's osteotome, as routinely used in orthognathic surgery, safe separation cannot be accomplished unless the blade is correctly applied to the suture and infraposterior compression of the pterygoid process is avoided.

    Angiomyoma is a benign tumor of smooth muscle origin which is most frequently observed in subcutaneous tissue of the extremities. But it is rare in the oral cavity because of the paucity of smooth muscle.
    We experienced a case of angiomyoma arising from the submucosal region of the lower muco-gingival junction. A 54-year-old man was referred to our department on November 25, 1984. On March 19, 1985, the tumor was completely excised under general anesthesia. The histopathological diagnosis was angiomyoma.

    Mesenchymal chondrosarcoma is a rare malignant tumor first described in 1959 by Lichtenstein and Bernstein. Only four cases of head and neck region have been reported in the literature of this country.
    We report a case of mesenchymal chondrosarcoma, occurring in the righ maxilla of a 32-year-old man. The patient came to our clinic with a chief complaint of swelling of the right maxilla. Intraoral examination revealed a dark purple swelling of the buccal gingiva at the right molar region. The teeth were shaking at the region.
    X-ray examination demonstrated anundefinitive resorption of bone of the right maxilla and the root. The clinical diagnosis was malignant tumor of the right maxilla. A right radical maxillectomy under general anesthesia was performed.
    The 4×3×3cm tumor was greyred smooth surface, hard and elastic. The histopathological features of the specimen showed islands of well-differentiated cartilage and highly cellar zones composed of small undifferentiated mesenchymal cells.
    We finally diagnosed the tumors as a mesenchymal chondrosarcoma.
    At follow up 23 months postoperatively, the patient had no sign of recurrence or metastasis.

    Recently we encountered a patient complaining of sore throat and pain on swallowing due to hypertrophy of the styloid process.
    Styloidectomy was performed with a good result. We described a brief report of the case with some discussion.
    This patient was a 40-year-old man who visited our hospital with chief complaints of sore throat and pain on swallowing.
    Examination of the oral cavity revealed slight reddishness of the area near the bilateral amygdaloid fossa in which bone-like processes was palpable with severe pain.
    The X-ray film revealed that the bilateral styloid processes abnormally extended to the lower inside, the tip of which extended near the mandible angle. Under a clinical diagnosis of bilateral hypertrophy of the styloid processes, bilateral styloidectomy was performed. From 1 week after operation, the patient complained of radiating pain of the right ear which subsided spontaneously without any special procedure.
    Within 1 month after operation, pain on swallowing and sore throat completely disappeared.
    At present, about 6 months after operation, the patient remained symptomless without recurrence.

    Mucoepidermoid tumor was first decribed as a distinctive entity by Stewart, Foote and Becker, who reported 45 cases in some 700 major and minor salivary glands tumors. Stewart and his colleagues originally considered that benign and malignant varieties of the mucoepidermoid tumor could be distinguished, but subsequently felt that all tumors of this type bear malignant potentialities. A distinction, however, can be made in a very general way between tumors likely to be of a low grade of malignancy and those that will probably be of higher grade malignancy; many low grade tumors are locally invasive only; they do not metastasis or recur if adequately excised.
    Generally, the prognosis for mucoepidermoid tumor is good. Except for those few tumors that grow rapidly and invade widly, the vast majority that display the characteristic indolent growth pattern may be cured by radical removal. In case of distant spread, the cervical lymph nodes are the usual site of metastasis. Visceral metastasis may also occur.
    The essential diagnosis features for mucoepidermoid tumor are epidermoid cell presence and mucus secretion. Mucoepidermoid tumor in which clear cells are present may cause difficulty. However, only when almost the entire tumor shows clear cells among cells of otherwise usual epidermoid appearance is the confirmation of the diagnosis helped since this type of hydropic change, when it occurs is very characteristic. When the tumor consists almost entirely of clear cell types monomorphic adenoma and acinic cell tumor as well as metastasis of renal carcinoma must be considered.
    We recently experienced one case of mucoepidermoid tumor considered to have occurred in the maxilla tuberosity in a 52-year-old man and reported on it which some comments based on the literature.

    We experienced an advanced oral cancer with a total resection of upper lip and partial maxillectomy, including nasal floor. Local flap was found to be inadequate to cover the large defect of lip and maxilla.
    The free forearm flap which contained brachioradialis muscle was used, and this offered an ideal solution for improving thickness and muscular function in the reconstructed lip.
    Postoperative condition of the flap was excellent, and healing of donor site was satisfactory. The follow up study of nearly 25 months found no recurrence or metastasis.

    There have been several reports concerning ectopic tooth in the maxilla, but eruption into the nasal cavity is rare.
    A case of tooth eruption into the nasal cavity was presented and previous reports were reviewed.
    Etiology of intra-nasal teeth is unclear, however developmental disturbance such as a cleft palate, dislocation by trauma, syphilis and maxillary infection were said to be etiological factors.
    Our case which developed in a 62 year-old female revealed a eruption of the tooth into the right nasal cavity due to osteomyelitis of maxilla in childhood.
    Roentogenographic and computed tomographic examinations confirmed presence of a tooth-like structure in the nasal cavity. As treatment, the tooth was extracted according to Partsch's approach under local anesthesia and it was found to be the right permanent canine tooth from morphological structure.

    A case of histiocytosis X with mandibular bone involvement in a 10-year-old boy was reported. The diagnosis was rather easily established not only from feature of other bone and chest findings, but also biopsy from the oral region. The final diagnosis was mandibular manifestation of histiocytosis of Hand-Schiiller-Christian type.
    The patient was treated with extirpation for the lower anterior lesion, and with 3, 000 rad irradiation for the ramus lesion of the mandible. Before the treatment of the oral maxillofacial surgery, combination chemotherapy of prednisolone, 6-mercaptopurine vincristine, and methotrexate had been carried out.
    The extirpated material was carefully examined histopathologically, immuno-enzyme histochemically (S-100 protein), and electron microscopically. These findings were also described in this paper.

    Chronic osteomyelitis of the mandible is a protracted disease often resistant to both antibiotics and surgical therapy.
    Four patients suffering from intractable chronic osteomyelitis of the mandible were treated with antibiotic irrigation-perfusion treatment and the results were as follows. In all patients, clinical symptoms disappeared and there was no evidence of recurrence during follow-up period from 18 to 33 months. In addition, radiographs indicated that the affected area tended to be restored normal bone.
    It is concluded that this therapy was very effective not only in chronic suppurative osteomyelitis of the mandible but also in intractable sclerosing type.

    Oral candidiasis has greatly increased in compromised hosts for an opportunistic fungus infection. Chronic mucocutaneous candidiasis (CMCC) is a chronic and persistent infection of the skin, the nails and mucous membranes associated with a selective defect in cell-mediated immunity.
    The case of a 60-year-old man with concurrent late-onset CMCC, myasthenia gravis and thymoma was reported. This late-onset CMCC is unique in that the infection begin after the third decade and almost each patient has thymoma. To the best of our knowledge, about 30 patients with CMCC and tymoma have reviewed. However some evidence of impaired cell-immunity were found in these patients, in the case reported here, no immunological defects were demonstrated except neutrophil dysfunction.

    Two cases of Basal Cell Nevus Syndrome (BCNS) are reported. They were diagnosed as BCNS because multiple jaw cysts, skeletal anomalies, and many other symptoms accompanied although basal cell nevus was lacked. Cleft lip or cleft palate (bifid uvula) was associated with each case.
    Accordingly the ratio of association of cleft lip and/or palate is 15.6%, and this is far more than the ratio in the normal population. This fact supports the conclusion by Gorlin and Sedano that association of orofacial clefting does not appear to be due to chance.

    Generally, the treatment of sialolithiasis aims at removal of the salivary stone, either intraorally and extraorally. It is thought that many cases of sialolithiasis can be cured by removing the salivary stone, except for some cases in which it is necessary to remove the salivary gland. The authors therefore devised a nonsurgical method by which a salivary stone could be removed safely and with certainty using endoscopy, and applied it clinically. So far 39 cases have been treated by this method and in 33 (84.6%) only the salivary stone has been successfully removed. With regard to extirpation of the salivary stone, this method could be emoloyed regardless of the location of the stone and was effective with stones up to 5mm diameter. The success of this method was affected by the degree of adhesion between the salivary duct and the stone, occlusion of the salivary duct or severe damage to the submandibular gland. It was confirmed that this method is a safe nonsurgical method with a high extirpation rate and should be considered before attempting the usual surgical procedure.

    A case of relatively large lipoma of the right neck is reported and thirty-three cases of lipomas treated in our department from 1965 to 1986 are reviewed.
    A 64-year-old man was admitted to our department complaining of a right neck swelling. The preoperative diagnosis was lipoma based on clinical findings as well as the image findings of CT scan and echogram. The tumor was excised through a cervical skin incision under general anesthesia. It lied between the platysma and the superficial layer of the cervical facia. The enucleated yellow and soft specimen was 12×7×6.5cm in size, and covered with a thin fibrous capsule. The histopathological diagnosis was lipoma. The prognosis has been good for about one year. From our statistical study the distribution by site of 33 lipomas is as follows: eleven cases in the check, five in the lower lip, five in the tongue, three in the submandibular region, two in the gingiva, the floor of the mouth, the soft palate, the preauricular portion each other and one in the neck.Males are more affected than females.76% of the patients are over 40 years of age.

    The non-Hodgikin, “extranodal” lymphoma is often found in the oral cavity. However, this type of lymphoma is seldom found in the jaws. Here we report a case of malignant lymphoma located centrally in the mandible.
    The patient, a 37-year-old woman, came to us because of a bonehard swelling of the mandible in the left side. Roentgenographically, a diffuse bone rarefaction was observed in relation with the swelling area. Histopathological findings of two biopsy specimens taken at different times were compatible with a granulornatous lesion. However, after total curattage under general anesthesia, the whole tissue was examined. This time the histopathological findings were in agreement with those of a malignant lymphoma. The patient received chemotherapy and radiotherapy, and has been under observation for 11 months without showing signs of clinical complications.

    The glycogen-rich clear cell adenocarcinoma of minor salivary gland is a very rare tumor. This entity, originally reported in 1975 by Mohamed and Cherrick, was distinguished from other recognized clear cell neoplasms of salivary gland origin metastatic adenocarcinomas, and glycogen-rich clear cell adenocarcinoma under a light microscopic, and by histochemical, and ultrastructural analysis. We experienced a case of glycogen-rich clear cell adenocarcinoma originating in the minor salivary gland of the left buccal mucosa, and reported the clinical course of a patient, and histopathologic findings and ultrastructural findings.
    The patient, a 56-year-old man admitted to Higashi-Nippon-Gakuen University Hospital in January, 1982 complaining of a tumor lesion of the left buccal mucosa. Oral examination revealed a lesion the size of a small finger, which was elastically hard and movablelesion. A tentative clinical diagnosis of malignant neoplasm of the minor salivary glands was made. An incisional biopsy was performed and the microscopic diagnosis was clear cell tumor. the tumor of left buccal mucosa was extirpoted, left upper neck dissection was conducted, and metastasis to the cervical lymph nodes was seen.
    A one year follow up showed evidence of left neck metastasis. Left radical neck dissection was conducted, and treated with chemotherapy.
    But 6 months later metastasis to the lungs was seen, and evidence of recurrence was noted at the interior of the mandiblular angle. The patient died March, 1986. Microscopic examination revealed an encapsulated, infiltrating tumor composed of nests, cords, and sheets of clear cells. The cytoplasma of the tumor cells was PAS-positive, diastase soluble, and Mucicalmin and Alcian blue negative. Electron microscopic examination revealed a glycogen. rich clear cell adenocarcinoma which is said to consist of two types of cells. One is rich organella, it seemed to have dark cells. The other had less organella with glycogen granule and appeared to have light clear cytoplasma.
