Recently, available interests concerning the biologic significance of the extracellular matrix and proliferating cells associated with periodontal disease has been increased. The distribution or expression of cellular proliferation by PCNA, macrophage detection by ${\alpha}$-l-antichymotrypsin, fibronectin playing a important role in host defence mechanisms indirectly, and transglutaminase that cross linked to fibronectin and stimulate fibrin stabilization were studied in inflammed and healthy gingiva. The excised tissue samples were fixed neutral formalin for 24 hours, embedded with paraffin, sectioned at 4-61lffi in thickness, and immunohistochemically processed by LSAB method. The positive reaction to PCNA was localized in the suprabasal and basal layer of inflammed gingiva and an increasing reactivity was observed than healthy gingiva. ${\alpha}$-I-antichymotrypsin positive cells were localized in the basal layer of inflammed gingiva, and there was no or rare positive cells in healthy gingiva. The positive reaction to fibronectin in inflammed gingiva was more than healthy gingiva,"and shown in the connective tissue subjacent to basement membrane of epithelium and in the periphery of the collagen fiber bundles. The positive cells by transglutaminase in inflammed gingiva were noted in suprabasal, spinous, and keratin layer of epithelium, and slightly increased in the capillaries of connective tissues. But the results of this study demonstrated in vitro reaction. Therefore, the role of PCNA,${\alpha}$-l-antichyrnotrypsin, transglutaminase, fibronectin and coefficient with other growth factor and extracellular matrix were further investigated in vivo.

Antiphospholipid antibody syndrome(APS) is a well-known clinical syndrome characterized by recurrent arterial or venous thromboses, recurrent fetal loss, thrombocytopenia, together with high titers of sustained anticardiolipin antibody(aCL) or lupus anticoagulant(LA). Although systemic lupus erythematosus(SLB) and APS may coexist, a high proportion of patients manifesting the APS do not suffer from classical lupus or other connective tissue disease. The patient has been defined as having a primary antiphospholipid antibody syndrome. We experienced one case of primary APS with recurrent fetal loss, recurrent cerebral infarctions, positive anticardiolipin antibody IgG and fluttering vegetation on the mitral valve, without other connective tissue diseases including SLE. Forty-three old female had 2 out of 11 criteria for the diagnosis of SLE, such as thrombocytopenia and positive antinuclear antibody, but did not meet whole criteria. The patient was treated with ticlopidine, and anticoagulant therapy was recommended.

Regeneration of interdental papilla damaged by periodontal disease is a very challenging task. So far, many dentists have devised and introduced great surgical methods. Comparing the pros and cons of the methods introduced so far, I came up with the best way to regenerate interdental papilla. Temporarily creating space between narrow interdental papilla, which cannot be solved by periodontal surgery alone, was a great help for connective tissue graft(CTG). The CTG was performed using a microblade, and only one vertical incision was performed off the gingival margin, and the graft was performed by inserting the grafts through here. Along with the orthodontic treatment, the area between the narrow interdental papilla was widened to make it easier for the CTG was carried out. After a period of maintenance, I was able to gather the teeth again with orthodontic force and regenerate the interdental papilla. I named this method ELSA (Enlargement of space-Labial graft-Squeezing-for Augmentation of papilla) technique.

The interdental papilla area is a difficult area for connective tissue graft (CTG) due to its narrow space. So Regeneration of interdental papilla is very challenging work. It is very difficult when the teeth have contact with adjacent teeth, but if there was only 3mm of space between the teeth, CTG was not very difficult. Therefore, through the orthodontic force, a 3mm space between the teeth was intentionally created. The CTG was performed using a microblade, and only one vertical incision was performed off the gingival margin, and the graft was performed by inserting the grafts through here. After a period of maintenance, I was able to gather the teeth again with orthodontic force and regenerate the interdental papilla. I named this technique ELSA Technique (Enlargement of space - Labial graft - Squeezing - for Augmentation of papilla). If interdental papilla is lost due to periodontal disease, ELSA techniques can regenerate interdental papilla very efficiently.

Purpose: The purpose of this study was to examine the trends of disease of residents who had treatment in primary health care posts in N-county over the past seven years (1997-2003). The data will assist in planning responses to changes in the health care environment and in planning health promotion programs. Method: A retrospective descriptive survey was conducted of the computerized records of primary health care done by community health practitioners over the last seven years. Cross analysis was conducted among the data using SAS, and the results were displayed in frequencies and percentages. The data were collected from May to September 2004. Results: The results of the study are as follows: 1. The six most frequent diseases were ranked as follows: diseases of the 1) respiratory system, 2) musculoskeletal system and connective tissue, 3) digestive system, 4) skin and subcutaneous tissue, 5) circulatory system, and 6) symptoms, signs and abnormal clinical and laboratory findings. Especially in 2002, circulatory system related disease rose two steps in the ranking and digestive system related disease went a step down. 2. The patients' use of primary health care posts over the past seven years continued to increase on the whole. Conclusions: According to these results, each primary health care post should carry out special health promotion programs that fit the local society of N- county and are in accordance with changes in health care needs.

Mucous membrane pemphigoid is uncommom disease in oral cavity and synonymous with cicatricial pemphigoid. This disease is caused by autoimmune reaction that autoantibody reacts antigen located in basement membrane and epithelium is separated from underlying connective tissue. It affects female over sixth decade, commonly. Oral mucosa, especially gingiva is common site but conjunctival, nasal, pharyngeal, laryngeal, esophageal, varginal mucosa and skin are involved. Intraoral findings show Nikolsky sign, irregular erythema, erosion, vesicle, and ulceration at mucous membrane. To differentiate from diseases of positive Nikolsky sign, should perform histologic, immunologic test. Histologic features show subbasilar cleft and direct immunologic features show IgG, C3 deposits at basement membrane in linear pattern. Mucous membrane pemphigoid is incurable disease because symptoms are repetitively improved or worsed for several years. Patiens are commonly managed with topical and systemic steroid. To avoid side effects of prolonged steroid therapy and to maintain immunosupressive effects, combination therapy of azathioprine with steroid is effective. This case reports that mucous membrane pemphigoid is diagnosed based on clinical and histologic features, is treated with topical, systemic steroid and azathioprine therapy.

The purpose of laboratory tests in the field of oral medicine can be divided into two categories: (1) medical evaluation of patients with systemic diseases that are planning to receive dental care and (2) diagnosis of patients with certain oral diseases. First, laboratory tests are commonly used to evaluate patients with systemic diseases who need dental management. A combination of multiple tests is usually prescribed as a test panel to diagnose and assess a specific disease. Test panels closely related to oral medicine include those for rheumatoid arthritis, connective tissue disease/lupus, liver function, thyroid screening, anemia, and bleeding disorders. Second, laboratory tests are used as auxiliary diagnostic methods for certain oral diseases. They often provide crucial diagnostic information for infectious diseases caused by bacteria, fungi, and viruses that are associated with pathology in the oral and maxillofacial regions. Laboratory tests for infectious diseases are composed of growth-dependent methods, immunologic assays, and molecular biology. As the field develops, further application of laboratory tests, including synovial fluid analysis in temporomandibular joint disorders, salivary diagnostics, and hematologic biomarkers associated with temporomandibular disorders and orofacial pain conditions, is currently under scrutiny for their reliability as diagnostic tools.

Hunter syndrome or mucopolysaccharidosis type II (MPS-II) (OMIM 309900) is a rare lysosomal storage disorder caused by deficiency in the activity of the enzyme iduronate-2-sulfatase. This enzyme is responsible for the catabolism of the following two different glycosaminoglycans (GAGs): dermatan sulfate and heparan sulfate. The lysosomal accumulation of these GAG molecules results in cell, tissue, and organ dysfunction. Patients can be broadly classified as having one of the following two forms of MPS II: a severe form and an attenuated form. In the severe form of the disease, signs and symptoms (including neurological impairment) develop in early childhood, whereas in the attenuated form, signs and symptoms develop in adolescence or early adulthood, and patients do not experience significant cognitive impairment. The involvement of the skeletal-muscle system is because of essential accumulated GAGs in joints and connective tissue. MPS II has many clinical features and includes two recognized clinical entities (mild and severe) that represent two ends of a wide spectrum of clinical severities. However, enzyme replacement therapy is likely to have only a limited impact on bone and joint disease based on the results of MPS II studies. The aim of this study was to review the involvement of joints in MPS II.

Purpose: This study investigated the validity of the Charlson comorbidity index (CCI) as a predictor of periodontal disease (PD) over a 12-year period. Methods: Nationwide representative samples of 149,785 adults aged ${\geq}60$ years with PD (International Classification of Disease, 10th revision [ICD-10], K052-K056) were derived from the National Health Insurance Service-Elderly Cohort during 2002-2013. The degree of comorbidity was measured using the CCI (grade 0-6), including 17 diseases weighted on the basis of their association with mortality, and data were analyzed using multivariate Cox proportional-hazards regression in order to investigate the associations of comorbid diseases (CDs) with PD. Results: The multivariate Cox regression analysis with adjustment for sociodemographic factors (sex, age, household income, insurance status, residence area, and health status) and CDs (acute myocardial infarction, congestive heart failure, peripheral vascular disease, cerebral vascular accident, dementia, pulmonary disease, connective tissue disorders, peptic ulcer, liver disease, diabetes, diabetes complications, paraplegia, renal disease, cancer, metastatic cancer, severe liver disease, and human immunodeficiency virus [HIV]) showed that the CCI in elderly comorbid participants was significantly and positively correlated with the presence of PD (grade 1: hazard ratio [HR], 1.11; P<0.001; grade ${\geq}2$: HR, 1.12, P<0.001). Conclusions: We demonstrated that a higher CCI was a significant predictor of greater risk for PD in the South Korean elderly population.

The diagnosis of juvenile rheumatoid arthritis (JRA) is based on patient's age at disease onset, symptom duration, gender, and clinical manifestations. JRA is of unknown origin, begins under the age of 16, and persists for a minimum of 6 weeks. JRA is categorized into three principal types, systemic, oligoarticular and polyarticular. Infection, other connective tissue diseases, malignancy, trauma, and immunodeficiency are discussed as differential diagnoses for JRA. Because of joint damage, focusing on early diagnosis and intervention, a vigorous initial therapeutic approach must be taken in patients who have poor prognostic factors. A multidisciplinary team approach is also important for the care of patients with JRA.
