The causes of periodontal disease have been descried as malocclusion, trauma from occlusion, local irritants and poor oral hygien. The systemic factor has also been considered as a etiologic factor of periodontal disease. On the other aspect systemic condition could be affected by periodontal disease. For the study of relationships between periodontal disease and systemic condition, twenty patients with periodontal disease and twenty persons with no periodontal involvement were evaluated for inorganic elements and organic materials in the blood. The results of the blood analysis of the two groups were as follows. : Phosphorus and alkline-phoshatase in the group with periodontal disease showed slightly increased phenomenon compared to the control group, and on the other hand calcium and calcium-phosphorus ratio decreased phenomenon. But there is no any significant alteration in the content of each element between the two groups.

This study conducted a 'specialist tooth brushing' method against the severely disabled once every other week. The purpose of this study is to analyze and validate the effectiveness of maintaining healthy periodontal management when consistent oral hygiene lasts with minimum stimuli for 24 - months. The conclusions were as follows. Table 2 compares the difference between group 1 and 2 from the 1^st to 11th management and verifies the actual difference in measurement of each index. Group 1 used a professional tooth brush while Group 2 used a general brush. There were found many significant differences in dental index. As for PHP, Oral Malodor index and gingival bleeding, it was found that one or two times of dental care can make substantial differences in dental health condition. These results show that as the number of toothbrush method has been increased, gingival bleeding and periodontal index are significantly improved, not to mention the improvement of gingivitis and periodontal disease. This is because periodontal tissue is affected by brushing method, brushing time and consistency of dental care. During the 6-month period, 20 minutes of active periodontal care was intensively conducted, and for 18-months the effect of consistent care was verified by 10-minute periodontal care once every other week. As a result of the test, it was found that there was no complete regression in the basic periodontal treatment and the periodontal health condition had been maintained for 24 months. Also this test shows that, despite of inconsistent dental hygienic care, regular plague control can prevent dental diseases and maintain the dental health. This study proved that periodontal condition can be maintained by periodontal care once every other week as the tooth brushing properly stimulates the gums with positive effect. Therefore, professional dental healthcareworkers should be designated for each facility for the disabled, and dental health of the disabled should be professionally cared on a regular basis, and consistent and repetitive management by the dental care specialist are required.

There were few reports about the fluoride concentration in bone and osteoporotic women. This study was designed to evaluate the relationship between the urinary fluoride concentration and periodontal condition in osteoporotic old women. Twentyeight postmenopausal women(Test group) and twenty-one premenopausal women(Control group) were examined. Bone mineral density(BMD) of lumbar spine(L2-L4) was measured by dual energy X-ray absorptiometry(DEXA). The urine samples were collected at early morning and determined with the help of a fluoride-specific electrode and Tisabbufferd samples. The results were as follows. 1. The mean urinary fluoride concentration in test and control group showed statistically no difference. 2. The bone mineral density(BMD) of the spine in test group was significantly lower than control group(p<0.05). 3. The significant negative correlation was found between BMD level and age after menopause $(p<0.001,\;{\gamma}=-0.526$. 4. The urinary fluoride concentration was not correlated with age, age after menopause and bone mineral density. 5. The urinary fluoride concentration was not correlated with periodontal condition.

The present study examines the effects of orthodontic treatment of surgically exposed impacted upper canines or ectopically erupted upper canines to periodontal condition and whether various opening procedures have significant difference in postoperative periodontal status. The subjects included 23 orthodontic patients(7 men, 16 women) with unilateral upper canine impaction treated either with closed eruption technique(group I), with apically positioned flap procedure (group II), and those with canines ectopically erupted through keratinized gingiva (group III). In each subject, the ectopic canine was orthodontically aligned, and changes in periodontal tissue were assessed by measuring keratinized gingival width, attached gingival width, probing depth and bone probing depth. In all three groups, the width of keratinized gingiva was preserved while showed no signs of detrimental periodontal condition such as gingival recession. In all three groups, no significant difference in periodontal pocket depth from control was observed. The width of attached gingiva was significantly greater in patients treated with apically positioned flap procedure(group II) than in patients on other groups.

The purpose of this study was to evaluate the relationship between the osteoporotic condition and periodontal condition in postmenopausal women with periodontitis. Forty three female postmenopausal patients with no systemic disease were grouped into 3 groups by their periodontal conditions; 12 mild periodontitis, 11 moderate periodontitis and 20 advanced periodontitis. From each patient, age of menopause was taken, alkaline phosphatase(ALP) and osteocalcin (OC) in blood and deoxypyridinoline (DPD) in urine were measured. Bone mineral density (BMD) of lumbar spine (L2-L4) was measured by dual energy X-ray absorptiometry. Periodontal and osteoporotic parameters were compared among the groups and correlation coefficient between them was evaluated. The blood ALP and OC levels were similar among the groups with different periodontal condition, whereas the urine DPD level and BMD were significantly lower in advanced periodontitis group than the other groups(p<0.01). Probing depth was negatively related with BMD (r=-0.5, p<0.01) and positively related with patient age and the duration of menopause (r= 0.32 and 0.35 respectively, p<0.05). Clinical attachment loss was negatively related with BMD (r=-0.66, p<0.01), and positively related with urine DPD (r= 0.37, p<0.05). These results showed that postmenopausal women with advanced periodontitis had significantly decreased bone mineral density and suggests that decreased bone mineral density in postmenopausal women could be associated with periodontal tissue breakdown.

Objectives: The purpose of the study is to investigate the influencing factors of metabolic syndrome on the periodontal disease in the Korean adults over 40 years old. Methods: The data were extracted from the Fifth National Health Nutrition Survey 2010. The subjects were adults over 40 years old. The periodontal diseases were examined by direct survey. The questionnaire consisted of the general characteristics of the subjects, oral health behavior, metabolic syndrome, and relation to periodontal diseases. CPI(community periodontal index) was measured. CPI indicates periodontal condition and classified into alveolar arch of the upper jaw and the lower jaw. A periodontal disease is defined as $CPI{\geq}3$(over 4 mm). The variables for metabolic diseases included hypertension, diabetes mellitus, dyslipidemia, and obesity measured as BMI. Results: Diabetes mellitus is closely related to periodontal diseases prevalence. Low level of HDL increase the periodontal diseases. Number of toothbrushung, use of dental floss and interdental toothbrush as for the number of toothbrushing, more than twice toothbrushing a day, and use of dental floss and interdental toothbrush reduced periodontal diseases. Conclusions: The risk factors of periodontal disease in Korean adults over 40 years old were sex, age, residence, monthly income, education level, smoking, diabetes and low HDL cholesterol.

A tooth with primary endodontic disease that demonstrates a periodontal defect might be extracted because of misdiagnosis as severe periodontal disease or a vertical root fracture. The aim of this case report was to demonstrate the long-term survival of endodontically treated teeth, which had been initially considered unsavable. With meticulous evaluation including the patient's dental history, clinical and radiographic examinations, teeth with primary endodontic lesions could be differentiated and saved after proper root canal treatment. Pain history, vitality test, and radiographic examinations, as well as a general periodontal condition check with periodontal probing on an affected tooth, might be the key methods to differentiate endodontic pathosis from that of periodontal disease.
