The cemento-ossifying filbroma is a well-demarcated and occasionally encapsulated neoplasm composed of fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum, or both. The greatest number of cases are encountered during the third and fourth decades of life and there is a definite female predilection, with female-to-male ratios as high as 5 : 1 being reported. The mandible is involved far more than the maxilla, and 90 percent of all cases are located in the mandible. The mandibular premolar-molar area is the most common site. Radiographically, the lesion is most often well defined and unilocular. Depending on the amount of calcified produced in the tumor, it may appear as completely radiolucent : more often it shows varying degrees of radiopacity. Some lesions may be largely radiopaque with a radiolucent halo. On microscopic study, the tumor is composed of fibrous tissue of varying degrees of cellularity containing calcified material. This may be in the form of trabeculae of osteoid and bone or basophilic ovoid calcifications that resemble cementum-like material. Admixture of the two types of calcifications are commonly seen. On this case, large cemento-ossifying fibroma has grown in the mandible and this lesion was treated by complete surgical excision and posterior iliac bone graft. A review of literature and a report of a case of cemento-ossifying fibroma are presented.

AbstractBases have been used in order to prevent the leakage of bleachingagents through dentinal tubules in bleached teeth.But the proximal surfaces where the actual resorption takes place havenot been protected.The purpose of this study was to compare the conventional basing method with the basing of the labial and two proximal surfaces to the cementoenamel junction.The bases were placed after conventional root canal treatment. Group I : 2mm thickness bases were placed to the level of labial cementoenamel junction line. Group II : 2mm thickness bases were placed to the level of all c-e J lines including cervical area. Control : No bases were placed.After placement of sodium perborate and 30% hydrogen peroxide mixtureinto the teeth, the changes of pH were measured.The results were as follows. 1. Group II showed smaller leakage of bleaching agents and was statistically significant difference compared to Group I.(p<0.05) 2. Group I showed no statistically significant difference compared to the control group. (p>0.05) 3. There were no significant among the upper and lower teeth groups in each group and between the groups.(p>0.05)According to the above results, it was considered that basing of thelabial and proximal surfaces to the cementoenamel junction can reduce the leakage of bleaching agents during bleaching procedure of pulplessteeth.

Although the use of the antibiotics has minimized the dangers of the spread of odontogenic infection to adjacent important organs, sometimes the fatal cases, such as Ludwig's angina, mediastinitis, intracranial complications from the odotogenic infection, may be occurred. The odontogenic infections or oral and maxillofacial region may involve the intracranial area through systemic circulation or by direct spread into the intracranial cavity. Headache, malaise, loss of appetite, chills, fever, vomiting, apathy, and irritability are usually followed by more specific involvement of the nervous system. We experienced one patient who died of intracranial complication from odontogenic infection. So we report the case and the literatures about intracranial involvements following odontogenic infections and dental procedures.

This study mainly deals with joint method in the center of a column of a korean traditional gabled building in the category of Jusimpo-Gye(柱心包係). And this study also consider the difference of joint method between inside(內部) and side(側面) of the building. Consequently, as inside beam gets bigger, the posotion of 'Soro(소로)' is changed from the center of the column outward of the column(toward 外目). And dislike inside at the side of a traditional gabled building, the joint method of 'Toeryangs(退樑)' is jointed with 'Teunjangyeo(뜬장여)'. According to this fact, we suppose that the joint method at the side of a traditional korea gabled building has little difference(古式) from that of the traditional.

AbstractPeriapical lesions develop as a result of immunopathologic response to irritants from infected root canal systems. Removal of these irritants from the root canal system and sealing the root canal space may induce healing of the periapical lesions. 83 periapical lesions diagnosed as periapical abscess, periapical granuloma, chronic nons- pecific inflammation, fibrosis and periapical cyst were evaluated for the distribution of immu- noglobulin containing cells. The influence of the state of root canal treatment on the distribu- tion of immunoglobulin containing cells has evaluated. All lesions were divided into a group with no treatment, a group with canal enlargement, a group filled with gutta percha, and a group filled with VitapexC calcium hydroxide). The distribution of immunoglobulin-contai- ning cells according to the presence of pain and fistula was also evaluated.The following results were obtained. 1. Statistically significant difference in the distribution of immunoglobulin-containing cells among periapical abscess, periapical granuloma, chronic nonspecific inflammation/fibrosis and periapical cyst were found.(Kruskal-Wallis analysis, P<^0.05) The number of immu- noglobulin-containing cells in fibrosis was remarkably lower than that of periapical abs- cess, granuloma and cyst. 2. IgM and IgA containing cells were predominantly observed in periapical abscesses and periapical cysts, respectively. 3. All periapical lesions showed a large number of IgG containing cells followed by IgM, IgA and IgE containing cells. 4. There was a decrease in all Ig-containing cells in the group with canal filling compared to groups without treatment or with enlargement. That is, there is a decrease in Ig -containing cells as treatment progresses. 5. No significant correlation existed between the presence of pain and fistula and the distri- bution of immunoglobulin containing cells in periapical lesions, (t-test) Results appear to support that immune response are actively involved in the development and progress in periapical lesions. The fact that distribution of immunoglobulins differ according to the state of endodontic treatment suggests that root canal treatment may alter the humoral immune response of the periapical lesions.

1) The number of the out-and in-patients had increased year after year (Table Ⅰ & Ⅲ). 2) Schizophrenia was the greatest number of the in-patients and its rate to whole was 49.1 percent, and neurosis was the greatest number of the out-patients and its rate to whole was 41.66 per cent (Table Ⅰ & Ⅶ). 3) In in-patients, hysteria revealed relatively large in percentage as 11.8% than the other groups (Table Ⅰ). 4) The rate of the male hysteria patients to all male patients was 3.5 per cent and the rate of female hysteria was 20.5 per cent (Table Ⅱ). 5) In in-patients, all the patients of general paresis and alcoholism were only males in sex(Table Ⅱ). 6) In in-patients of schizophrenia, the ratio of the male patients to the female patients was 57.0 : 43.0, but the each rate of each total numbers of the all diseases of the both sexes was almost same (Table Ⅲ). 7) The largest age group of the all patients was between 21∼30 years old, and the next was between 31∼40 years in in-patients (Table Ⅲ). 8) The largest age group of schizophrenia patients was between 21∼30 years and that of M.D.R patients was between 31∼40 years in in-patients (Table Ⅲ). 9) In in-patients of hysteria, the largest age group was between 31∼40 years, and the next was between 21∼30 years (Table Ⅲ). 10) The results of treatment in in-patients were as followings; Recovered; 27.6% Much improved; 43.1% Slightly improved and no changed; 28.2% (Table Ⅳ) 11) The results of treatment in schizophrenia of the in-patients were as followings; Recovered; 19.1% Much improved; 48.3% Slightly improved and no changed; 32.1% (Table Ⅴ) 12) The mode of treatment had been somewhat changed during last 8 years from 1960 to 1967 in treatment of the in-patients (Table Ⅵ). (1) The combined therapy of tranquilizers and EST had been increased, but the therapy of tranquilizer alone or EST alone had been decreased, compared to 1960. (2) The therapy of ICT in the treatment of in-patients had been much decreased.
