    We have introduced a new technique for reconstruction of oral mucosa, naming it reversed dermis graft (RDG). In RDG the depithelialized skin is turned inside out and transplantated into the recipient bed. The surrounding mucosal epithelium gradually covers the graft while the transplanted tissue inhibits wound contracture.
    Mucosal defects in the oral cavity in 16 cases were repaired with RDG. Clinical observation was carried out to evaluate this method.
    1) In this series of cases, all oral cavity mucosal areas were reconstructed with RDG except for palatal mucosa. The maximum graft size was 9×5cm.
    2) All grafts were reepitheliarized with the surrounding mucosal epithelium within about 5 weeks. Hair growth, keratinization and formation of dermal cyst were not seen in the reconstructed area.
    3) The grafts contracted in all cases and were about 55% of their original size.
    So, compared with the usual method, RDG has many advantages. In this report the biological background of RDG and operation technique were described.

    To determine the value of the reconstructive method by the autogenous cancellous bone and marrow chip grafts to mandibular defect sites which involved upper areas from Foramen mandibulae, i.e., Ramus mandibulae, Processus condylaris and coronoideus, a study of 56 and the macroscopic, radiographic, histopathologic, and the fluorescent findings of adult dogs was done with the conclusions as follows:
    1. Although minor osteogenesis was perceived to locally exist at the end of the host bone, no bone formation was observed in nongrafting groups both under the periosteum or nonperiosteum.
    2. Normal remodelling of Processus condylaris, Caput mandibulae, Processus coronoideus and Ramus mandibulae was viewed for 4 months in grafting groups with periosteum. Caput histologic construction was nearly normal. Hardness of the new bone was sufficient and smooth bony adhesion to the host bone was observed.
    3. Only the bone grafted proximal to the host bone was fixed and that grafted far from it was absorbed, and functional morphologic recovery of Caput mandibular was found to be negative in grafting groups without periosteum.
    4. Autogenous cancellous bone and marrow chip grafts were especially efficient, when periosteum exists, and this suggests multiplicated effect between periosteum and the grafted bone. Periosteum effectively acted on inhibiting the surrounding tissue from the invading grafted bone.

    This study was performed to examine the osteogenesis-inducing capacity of hydroxyapatite (HAP) with non-sintering or sintering condition. Three HAPs, Undrying slurry HAP, drying HAP at 200°C and sintering HAP at 800°C, were used. Each HAP was filled into an osseous cavity prepared in the rat mandible. Observation periods were 3 days, 1, 3, 8 and 12 weeks after the filling of each HAP into the osseous cavity.
    Histologic sections showed osteogenesis around each HAP particle. Each HAP particle was embedded in the new bone unlike tricalcium phosphate. Also, it was difficult to determine the difference of osteogenesis between each HAP.
    In early periods of HAP filling, macrophages or multinuclear giant cells phagocytized HAP micro-particles. Thus, this study indicated that HAP had osteogenesis-inducing capacity which was not affected by sintering conditions in the synthesis process of HAP. We also proposed that the particle size of HAP had to be larger than the size of the particle phagocytized by phagocytic cells for the inducer of osteogenesis.

    We examined the effect of retinoic acid (RA), EGF and cholera toxin on the colony formation in the primary culture of the epithelial cells taken from the rabbit oral mucosa and the following results were obtained:
    1. RA showed the most stimulatory effect on squamous colony formation at the concentration of 10-6-10-7 M. RA also stimulated in part of adenocytoid colony formation by the mucous metamorphosis.
    2. The cultures containing EGF revealed about twohold to threehold increase in the colony numbers as compared with the controls. The optimal concentration for the growth of epithelial cell colonies was at around 1-10ng/ml of EGF. Inhibitory effect for the colony formation was observed at 100 ng/ml. Furthermore, it is to be noted that the induction of mucous metamorphosis by EGF was not seen.
    3. The enhancing effect of CT on the colony formation was observed in the number of colonies twice as much as that of the controls at the concentration of 10-8-10-9 M.
    4. It was clearly observed that synergetic effect in the combination of RA and EGF or EGF and CT revealed about two fold increase in the number of colonies as compared with a single addition of these reagents to the cultures.
    5. RA or the combination of RA and CT or RA and EGF did not stimulate the formation of original cell colonies which consisted of small polygonal cells. However, original cell colony formation was significantly stimulated by the addition of EGF.

    A case of mucoepidermoid carcinoma seen in the left submandibular gland of a 47-year-old male is described.
    Recurrence and distant metastasis were apparent about one month after the operation that included left radical neck dissection, resection of the left submandibular gland and dissection of the floor of the mouth. The patient died 4 months after the operation.
    At autopsy, extensive metastasis in bones, lung, liver, kidneys, pancreas, brain and lymph nodes was observed.
    Salivary gland scintigraphy with 67Ga-citrate, 99mTc-pertchnetate and 20M-chloride was performed preoperatively and an extensive up-take in the left submandibular tumor area was indicated with all of these radionucliedes.
    Only 15 reports of the mucoepidermoid carcinomas in the submandibular gland have been found in a review of Japanese literature and 3 of them were histologically classified into the highly malignant (poorly differentiated) tumor.

    Malignant melanoma is a disease arising from the melanocytes and having a tendency of distant metastasis even in the early stage. Unfortunately, the effective treatment is not established and the prognosis is unfavorable in most cases. This paper described a rare case of malignant melanoma originating from the parotid gland. The patient, a 76-year-old man, was referred to our clinic with the chief complaint of preauricular region swelling.
    A diagnosis of parotitis suppurativa was based on clinicopathological findings. The treatment was initially effective, but thereafter the parotid gland increased gradually and therefore parotidectomy was performed one year and 4 months after the initial diagosis. At this point the pathological diagnosis of malignant melanoma was established. Although the patient was treated with OK-432, BCG and N-CWS and temporarily had a favorable response, finally he died of renal insufficiency complication after 2 years and 4 months. The autopsy was made and the metastases in various parts of the body was especially reported here.

    Epidermoid cyst is a congenital cyst caused by the impaction of embryonal ectoderm and is known to occur with relatively low incidence within the oral cavity, rarely occurring in the jaw bone.
    The authors have recently experienced one case of epidermoid cyst which developed within the mandible, and report the outline of this case with further discussion in reference to the literature.
    The patient is a 44-year-old male who visited the hospital on July 14, 1984 complaining of swelling at the left mandibular molar.
    X-ray revealed a well defined oval, hen egg-sized radiolucency from the distal area of the lower first molar throught the mandibular branch. In biopsy conducted under the clinical diagnosis as mandibular cyst, it was pathologically diagnosed as epidermoid cyst.
    Accordingly, cyst extirpation was performed under general anesthesia with NLA on August 9, 1984. There was little adhesion between the cystic wall and the surrounding bones and the cyst was easily ablated. The cystic cavity was kept open in accordance to subcativity formation method. The patient has shown a favorable course for these three months following surgery. The authors will continue careful observation on the patient's prognosis.

    Chondrosarcoma of the jaws and facial region is extremely rare. We had a chance to treat and report a case of chondrosarcoma in the anterior region of the maxilla of a 22-year-old woman.
    Clinically, the painless swelling of the maxilla extended from the right lateral incisor to the left central incisor in the palatal side, but its borderline was relatively clear.
    The X-rayshowed a cotton-wool appearance.
    The histological appearance showed lobular growth of the cartilaginous tissue, with moderate nuclear atypism, pleomorphism and mitotic figures.
    Partial maxillectomy was done. The postoperative course was uneventful and during a 5-year and 6-month interval after surgery, there has been no evidence of recurrence.

    Gingivostomatitis is the most common manifestation of primary infection with herpes simplex virus (HSV).
    Since HSV has an affinity for cells of ectodermal origin, infection of the oral mucosa with HSV results in intraepithelial vesicles. These vesicles soon burst and cause erosion or shallow ulcer because the submucosal connective tissue it rarely involved in replication of the virus.
    The present paper reports the clinical and laboratory findings and interferon therapy in a case of primary herpetic gingivostomatitis having unusual deep ulcers developed on the lip.
    A 7-year-old boy came to our clinic on September 24, 1983 with chief complaint of the burnlike pains on the lower lip. About 3 days before the visit to our clinic, he had moderate general malaise and emergence of lip pain. On oral examination, deep ulcers were observed only in the lower lip mucosa. He complained of pain even by feather touch in this region. The regional submandibular lymph nodes were enlarged and painful to the touch. He had body temperature of 36.5°C. Laboratory data included red blood cells 516×104/mm3, white blood cells 5, 500/mm3, hemoglobin 13.7g/dl, hematocrit 41.8%, differential counts of leukocytes, neutrophil 62%, eosinophil 2%, basophil 0%, lymphocyte 32%, monocyte 4%, CRP positive (2+). These hematologic data seemed generally to indicate viral infection. Since HSV-1 was isolated by tissue culture work from the swabs of mucosal lesions, this patient was diagnosed as herpetic gingivostomatitis. Seven days later, numerous ulcerative lesions appeared in the oral mucosa including lower lip, tongue and gingiva, and the body temperature elevated up to 39°C. While the inflammatory reaction subsided by administration of antibiotics and anti-inflammatory drug, the mucosal lesions were treated with the gelfoam containing human interferon-ß. 2 months later, the lesions healed with linear scars at the sites of mucosal lesions. When serum of this patient was assayed for antibody level against HSV-1 by complement fixation test at various time intervals during the therapeutic period, this antibody titer in recovery period showed a four fold increase in comparison to that at onset. From these findings, this infectious disease was precisely diagnosed as primary herpetic gingiovastomatitis.

    Although bone metastasis of a malignant tumor is not rare, it is generally thought that intraoral maxillary metastasis from other organs is rare.
    The authors experienced a case of mandibular metastasis of the renal cancer, on which a report is made here with literature consideration thereof.
    Patient: S.S. 49-year-old man (office man)
    Initial medical examination: November 24, 1981
    Chief complaint: Formation of a painless tumor at his left mandibular mental foramen region
    Family history: Pneumonia (20 years ago) and sciatica (12 years ago)
    Present illness: About a month ago, a thumb-sized swelling was noticed at his left cheek, and he consulted a town doctor for lower lip paresthesia. Chemotherapy was performed for 10 days without symptomatic improvement and he came to our Department of Oral Surgery.
    Present examination: The patient had moderate general physique and eutrophia. His countenance was nearly symmetrical, however, a thumb-sized elastic and hard tumor was palpable at his left mental foramen region. On the affected side intraorally, there observed a defect of the mandibular molar and a tumor at the dental root of the mandibular premolar. There was neither gingival inflammation nor swelling of its attached submandibular lymph node.
    Results of clinical examinations: X-ray exploration revealed a thumb-sized and comparatively well-defined bone resorption shadow, centering around his left mental foramen region. There were no abnormal values obtained from general blood examinations.
    Treatment: The tumor suspected of mandibular cyst was extirpated under general anesthesia.
    Results of histopathological examination: The extirpated multinodular solid tumor, covered with connective tissues, was diagnosed pathologically as a clear cell carcinoma with a honeycomb-like structure which was delimited by the abundant strome and blood vessels.
    Postoperatively, the intraoral wound showed good healing, process however, the lung or kidney was suspected as the primary site of this tumor, and a co-exploration by the Department of Surgery and the Department of Urology and a detailed examination detected left renal cancer of the patient who was then transferred to be radically operated for renal cancer.
    Literature examination of such cases revealed that intraoral bone metastasis of renal cancer was rare. The treatment of intraoral metastatic cancer is usually perfomed at its relatively early phase and its prognosis was frequency poor depending on the result of the treatment for its primary focus.

    In this paper, a 38-year-old female suffering from myxofibroma of the maxilla was referred to the clinic with chief complaint of a painless swelling in 1456 region. Intraoral examination showed an elastic-firm and nontender mass at the buccal gingiva of 456 region.
    Radiographs revealed a multilocular lesion with delicate trabeculations in 1456 region and encroaching on the antrum.
    Microscopic examination showed myxomatous-appearing fibrous connective tissues composed of spindle-shaped and stellate cells. Ultrastructurally, these cells were seen to be fibroblast-like Occasionally myofibroblast-like and histiocyte-like cells were also present in this tumor. It was impossible to clarify if the origin was odontogenic.

    For the analysis of physical configuration of facial soft tissue, an automatic system for taking standardized photographs of a face at five different angles has been developed.
    This system consists of;
    1) the head-holding unit with ear rods,
    2) the chair with height adjustment and rotation mechanisms,
    3) the electronic control system,
    4) the single-lens reflex camera, and
    5) the background screen.
    The head of a patient will be fixed by ear rods inserted to the ear holes at the position that the Frankfort horizontal plane parallels the floor level.
    The focal distance for photographing is 1. 5 meter from the center of the line connecting the ear rods which is equal to the distance from the anode to the midsagittal plane of roentgenographic cephalometry.
    Photographs are automatically taken in sequence at angles of 0 (full face), 90° & 45° to the left, and 45° & 90° to the right.
    At the front angle, when the exposure button is pressed and the photograph is taken, the chair automatically turns to the next angle. Thus, five standardized photographs in sequence at different angles can be taken.
    The comparison of pre- and post-operative facial configurations can be done by examining these photos, and quantative comparison of the face at five different angles is also available.

    In the two years following the inception of the department of oral surgery at Saga Medical School in October, 1981, 1, 446 patients were referred to us and 277 patients were hospitalized. The system of recording medical histories which we use in our hospital is the one developed by L.L. Weed in 1968, which he named the problem-oriented system (POS).
    1. All the cases have been classified into the following 10 groups according to disease: inflammation (305 cases, 21.1%), disease of teeth (297 cases, 20.5%), malformation (275 cases, 19.0%), cystic disease (133 cases, 9.2%), trauma (113 cases, 7.8%), benign tumor (89 cases, 6.2%), temporomandibular joint disease (66 cases, 4.6%), oral mucosa disease (50 cases, 3.5%), malignant tumor (24 cases, 1.6%), and others (95 cases, 6.5%)
    2. In terms of age distribution, patients in their twenties were the most numerous.
    3. In terms of geographical distribution, 1, 292 patients (89.3%) were from Saga Prefecture.

    Among 309 patients with the squamous cell carcinoma of the oral cavity treated at Department of Oral Surgery, Kyushu University during a period of twenty years, from 1963 to 1983, 11 patients (3.6%) with retromolar cancer were examined with regard to their clinical and histological findings and the causes for poor prognosis
    Chief complaints of the patients at the time of the first visit were pain and trismus. Most cases were in advanced condition as nine cases were classified into stage II and IV (4 and 5, respectively). In most instances the lesions were ulcerated and roentgen examination revealed mandibular bone destruction in 4 cases.
    Five cases were only treated by radiation and 4 of them died due to recurrence of the primary lesion. One died of other illness.
    Six cases in the last five years received surgical treatment combined with preoperative radiation and chemotherapy and another recent case received only surgical treatment. Radical neck dissection was performed on 6 patients and 4 had histologically positive lymph nodes. More than three metastatic lymph nodes were noted over multiple levels in all cases.
    Five of the surgically treated cases had primary lesion recurrence and the pterygomandibular region was the most frequent recurrence site. Of 4 fatal cases, two died of primary lesion recurrence and the other two died of lung metastasis and pneumonia, respectively. The crude survival rate in all cases was 37.5% (3/8) for 2 years and 12.5% (1/8) for 3 and 5 years.
    This poor prognosis of retromolar cancer patients could be accounted for by the difficulty in control of the primary lesion. Several possible reasons are as follows:
    1. Most cases rapidly develop to the advanced stage.
    2. It is difficult to determine an exact border of tumor invasion and accordingly difficult to get an adequate surgical margin and exposure.
    3. Radiation therapy is less effective on the retromolar cancer.
    4. There is difficulty in early detection of recurrence.

    A 41-year-old female with a painless mass in the right subauricular region had first noticed the mass 20 years ago but was not treated. The mass was circumscribed and superfacial. Past and family histories were negative.
    We diagnosed a benign tumor of the subauricular region and enucleated it under local anesthesia. It was easily removed, and the tumor was a hard mass 19×22×7mm in size, 1.9g in weight, yellow and gray in color.
    Histologically it was composed of nests or a mass of shadow cells that did not stain with haematoxylin but appeared as sheets of eosinophile in which the outline of the individual cells and of their nuclei were visible as slightly darker areas and ossific tissue. More darkly stained basophilic cells appear adjoining shadow cells.

    Clinical significances of intravenous hyperalimentation (IVH) were evaluated on 10 patients, who suffered from terminal stage of oral carcinoma or radiation stomatitis, or who need nutritional management before and after surgical operation.
    Clinical status, weight gain, and biochemical tests before and after IVH method application were compared.
    The results have comfirmed that IVH was one of the very effective and significant methods for general nutritional management of oral and maxillofacial surgery.

    A case of peripheral osteoma occurred in the ascending ramus to just below in a 26-year-old man is presented. The patient noticed a painless swelling mass in the right side of buccal region followed by contusion in the age of 14. The localized hard mass had been growing gradually, and showed no symptoms except for facial asymmetry. Radiographic examination revealed a pigeon egg-sized, rounded, dense and radiopaque mass which protruded from the lateral surface of the mandibular ramus. Histopathological examination showed a finding of compact osteoma characterized by a dense lamellar bone mass with few stroma.

    Macroglossia is a clinical term denoting partial or general thickening of the tongue. This disease is known to affect jaw and facial development, occlusion, and articulation especially during patient's growth period.
    We recently encountered a 4-year-old female with lymphangiomatous macroglossia who visited us with the chief symptom of thickened tongue. At the initial examination, occlusion was possible but after 90 days of conservative treatment open bite was observed. Since the tumor extended diffusely throughout the entire tongue, the tongue size was surgically reduced according to the Rheinwald and Thoma method. Immediately after the operation, the open bite with a maximum distance of 10 mm between the anterior teeth disappeared.
    Lingual angiography performed in this patient demonstrated the usefulness of the procedure in differential diagnosis of this disease from hemangioma.

    Based on the data from sagittal splitting osteotomies (Obwegeser-Dal Pont's method) for 19 cases and from body ostectomies for 14 cases, each method was evaluated by clinical assessment to elucidate the distinct characteristics of two methods. The clinical problems about body ostectomy will be especially discussed.
    These two methods were almost the same in the amount of mandibular displacement, but the sagittal splitting osteotomy seemed to be preferable for the cases which had the transverse deviation deformity. Body ostectomy consisted of the two procedures of bone cut and bone resection Bone cut procedure included vertical cut and step cut, and bone resection procedure included Vshaped, rectangular and reverse V-shaped resection. Bone resection in the body ostectomy was not performed on the second nor third molars. This fact suggested that the body ostectomy method was indicated for the cases which had stable occlusion of the teeth on proximal segments. The assessment of postoperative disturbance of temporomandibular joint indicated a less incidence for the body ostectomy than the sagittal splitting osteotomy. Both methods had the same incidence in paresthesia of the lip and mental region 3 months postoperatively, however the body ostectomy showed a more delayed recovery from paresthesia. A less incidence of paresthesia was observed in the vertical cut procedure on the first premolar or in the step cut procedure. U1, L1, and Pog were found to change more anteriorly in the sagittal splitting osteotomy and more superiorly in the body ostectomy.
    Consequently, the body ostectomy was demonstrated to have the following advantages: This method could reposition the mandible to the same extent as sagittal splitting osteotomy, disturbed temporomandibular joint in remarkably fewer cases, produced superior postoperative changes of the skeletal landmarks on the contrary to anterior changes with sagittal splitting osteotomy, and could avoid postoperative paresthesia with the proper bone cut procedure.
    We concluded, therefore, that body ostectomy could present a satisfactory result in the case of stable occlusion on a proximal segment, no steep mandibular plane, lesser transverse deviation of mandible and no considerable amount of displacement.

    Two cases of Apert's syndrome were presented. The manifestations of Oxycephaly, Syndactyly, Frontal bossing, and Midfacial retrusion with some intraoral minor anomalies were associated with the patients.
    The craniofacial forms in both patients were examined by the measurement analysis of x-ray cephalograms.
    Discussions were mainly focused on the relation between the cranial forms and the maxillary retrusion, and on the role of the cranial base synchondrosis and synostosis concerning the maxillary growth.

    Blood eosinophil and eosinophilic infiltration of tumor tissues in patients with oral squamous cell carcinoma and no allergic diseases were investigated. The patients with blood eosinophilia (>6.0%) were 10/85 (11.8%), and the patients showing increase of % blood eosinophil more than 5% as compared to that of the preirradiated state within 2 months postrirradiation were 20/72 (27.8%). On the other hand, high grade eosinophilic infiltration (>50 cells in 400 field) to tumor tissues was observed in 7/76 of biopsy specimens and in 3/50 of operated materials.
    In a case with eosinophilia and eosinophilic infiltration of both biopsy and operated materials, the correlation of eosinophilia with tumor growth and regression was strongly suggested.
    These results indicate that although eosinophilia is induced by oral cancer as well as irradiation, tumor cells may produce an eosinophil chemotactic factor (ECF) in tumor-induced eosinophilia.

    The sagittal split mandibular ramus osteotomy, established b Obwegeser in Europe, is recognized and utilized internationally as an useful procedure fo orthognathic surgery of mandibular prognathism.
    However, as indicated by the anthropologist, the skeletal architecture of Orientals including Japanese is not consistent with those of the Caucasions. The authors have modified the sagittal split mandibular ramus osteotomy so it can be applied for the maxillomandibular structures of Orientals. The present article demonstrates the newly modified surgical procedure with a report of 3 cases treated by this technique.

    Generally it is more difficult to treat adult patients suffering from open-bite because of relapse occurrence. Recently we had a good result in treatment of open bite by application of intermaxillary elastic traction with bite splint. For treatment of three cases diagnosed as arthrosis of the temporomandibular joint with open bite, this method was indicated.
    Intermaxillary elastic traction was made for 28 days to 2 months. Improvement in open bite was attained in 10 to 21 days. To prevent the relapse after closing open bite, we instructed them to use a chin cap during the night at least for half a year. None of these cases had relapse of open-bite or TMJ arthrosis.
    As improvement mechanism, it was considered that open bite closing was obtained by inclination of upper anterior upward.
    So we can conclude that this method was useful for treatment of the open-bite patient with a normal molar occlusion.

    The method of intraoral oblique sagittal splitting oseotomy, a new modification of the sagittal splitting osteotomy, is presented. This procedure is distinct from Obwegeser-Dal Pont method in the following two points; 1. Horizontal osseous incision is made through the cortex medially, extending just only posterior and superior to the lingula. 2. Lateral bone cut is performed down the anterir border of the ascending ramus along the external oblique ridge directly to the inferior border of the mandible with slight oblique direction to the sagittal plane, not extending to the second molar.
    Thirty-two mandibular prognathism patients with or without anterior open bite have been corrected by this procedure. The advantages of this technique are reduction of operating time, less blood loss and fewer complications. This osteotomy is indicatd for mandibular prognathism with less than 15mm set back required.

    The patient was a 51-year-old housewife with the chief complaint of contact pain in the hard palate. The past history disclosed tuberculosis of the pulmonary, the uvula, the tonsils and the larynx.
    Intraoral examination revealed a deep ulcer in the center of the hard palate. It's surrounding mucosa was markedly reddening, but not indurated. The ulcer was about 13×10mm in size, circular in shape. The edge was uneven, and partially undermined. The base was covered with grayish-white coating.
    The clinical and histopathological diagnosis was tuberculosis of the hard palate.
    Isonicotic acid hydrazide was administered for 6 months. The ulcer was completely healed.

    A 76-year-old male, patient with lower jaw pain was studied.
    Though the patient had no history of angina pectoris and no chest pain, ambulatory electrocardiography showed the elevation of ST segments in early morning, which followed lower jaw pain. This transient elevation of ST segments was reduced by coronary vasodilator and at that time, the lower jaw pain was completely relieved.
    In this way, a careful history and long-recording electrocardiography established a diagnosis of the variant form of angina pectoris and it reffered pain in the lower jaw.

    Now, we had a chance to use Calcitite (Calcitek, Inc.) on clinical cases.
    Cacitite is a rounded, particulate form of synthetic polycrystalline hydroxylapatite. It is a dense, 100% pure radiopaque ceramic and is not resolved after implantation. Calcitite is classified two different particle sizes. One is 20-40 mesh (1.5g or 4g per ampul), and the other is 40-60 mesh (0.5g per ampul). The former is used for alveolar ridge augmentations and the filling of bone defects in the field of oral surgery. The latter is used for the filling of very small bone defects such as periodontal lesions. Calcitite in each ampul is already sterilized. For using Calcitite, the material wetted with sterile saline is easily applied to the affected area with an insertion syringe. Then, we may mix Calcitite particles with the autogenous cancellous bone.
    In this study, 72 patients (Cyst in maxillary and mandiblar bone (31 cases), Chronic marginal periodontitis (20 cases), Cleft of lip, jaw and palate (7 cases), Progenia (4 cases), Benign tumor (4 cases) and Others (6 cases)) were treated with this material, and were recorded on the protocol.
    As the result, the following evaluation were obtained:
    1. Markedly useful 6 cases (8.3%)
    2. Moderately useful 34 cases (47.3%)
    3. Slightly useful30 cases (41.6%)
    4. Not so useful2 cases (2.8%)
    5. Undesirable0 cases (0%)
    Two problems were found in a few cases. One was marked post operation inflammation and the other problem was a small amount of Calcitite which was naturally discharged from bone defects. But we supposed they were related to the method or technique of operation.
    Calcitite was considered to be the useful material for bone defects of oral surgery and periodontal lesions.
