Purpose : The purpose of this study is to directly understand the health condition of residents of mental health sanatoriums nationwide, which has been difficult to ascertain in surveys conducted to date. The study presents specific measures for improving the health of these residents. Methods : A "physical examination questionnaire for residents of mental health sanatoriums" was developed to check the basic physical condition of residents, and 20 out of 59 mental health sanatoriums nationwide were randomly selected. Medical personnel visited the sanatoriums, interviewing and examining the residents in person. A total of 396 health surveys were completed. Results : Many of the residents were underweight but had abdominal obesity. It was confirmed that chronic diseases among the residents were not diagnosed early or were not properly managed. Among the subjective symptoms complained of by the residents, musculoskeletal symptoms were the most common. Oral examinations revealed a serious level of oral health problems among the residents, including dental caries and missing teeth. Basic physical examinations found health problems that required additional examination or medical treatment. Blood pressure abnormalities made up the highest percentage of the health problems. Conclusion : Regular health surveys are needed to determine the health condition of residents of mental health sanatoriums. Access to and quality of primary medical services within the sanatoriums need to be dramatically improved. A delivery system for severe diseases and emergency medical care in the sanatoriums should also be specifically presented. The residents should be notified upon admission and during their stay that they have the right to the enjoyment of the highest attainable standard of mental and physical health. The issue of health rights should be addressed within a larger framework of reorganizing management plans for people in the community - not only residents - with chronic mental illness.

Purpose : In recent years, essential oils have been produced using natural extracts for various uses. Their functionality is currently being tested not only for cosmetics and perfumes but also for other categories of products. Therefore, this study verified their antibacterial effects on S. mutans, P. gingivalis, and L. gasseri which are the representative strains that cause oral diseases. Methods : Eighteen types of natural essential oils were made at a concentration of 50 % (v/v) using Tween 20, and their antibacterial effects were verified by applying S. mutans, P. gingivalis, and L. gasseri. The antibacterial effects were measured with the disc diffusion method. All the experiments were repeated three times, and the mean value of three measurement values for each variable was used for data analysis. A one-way analysis of variance was conducted using these mean values. Results : Of the eighteen types of essential oils tested, sixteen types showed antibacterial effects on S. mutans, and sixteen and fifteen types exhibited antibacterial effects on P. gingivalis and L. gasseri respectively. The types of essential oils with high-level antibacterial activities were geranium, may chang, and bergamot for S. mutans, lemongrass, bergamot, and eucalyptus for P. gingivalis, and lemongrass, machan, and geranium for L. gasseri in order of antibacterial effect. This result was statistically significant (p<.001). In addition, in the case of mandarin oil, it was found that there was no antibacterial activity in all three strains. Conclusion : This study proved the antibacterial activities of essential oils, which are used for various purposes in daily life, against dental caries and periodontal diseases. The study results will likely be applied to different prevention programs for oral health and broadly used to develop products such as oral care items and dentifrices.

Xerostomia is subjective feeling of dry mouth, a symptom that may or may not be accompanied by hyposalivation, an objective decrease in salivary flow. There are many causes induced xerostomia like drugs, salivary gland diseases, radiation therapy to the head and neck region, Sjogren syndrome, emotional stress etc. Insufficient salivary flow creates complications with oral candidiasis, dental caries, periodontitis, halitosis, dysgeusia. So finally, these complications lead to an overall decline in quality of life. Managements of xerostomia are eliminating or alterating the etiologic factors, relieving symptoms, preventing or correcting the consequences of salivary dysfunction, treating underlying disease and stimulating salivation. One of the salivation stimulation agents studied to treat xerostomia was the pilocarpine muscarinic agonist. Pilocarpine is one of salivation stimulants, a parasympathomimetic drug and non-selective muscarinic receptor agonist. Systemic pilocarpine has been used to stimulate salivary secretion. But systemic administration of pilocarpine has limitations such as increased risk of side effects and contraindications. Side effects of systemic pilocarpine administration are sweating, urinary and gastrointestinal disturbance, risk of cardiovascular and pulmonary disorders. This drug must be used carefully by patients with controlled asthma, chronic bronchitis, pulmonary or cardiac disease. Patient with acute asthma, narrow angle glaucoma, iritis should not use pilocarpine. Like this, systemic pilocarpine has many limitations. So, many investigators also have looked at the effectiveness of topical pilocarpine. Here we present patients with xerostomia which was relieved by pilocarpine mouthwash.

Purpose: the study aimed to compare the quality of life (QOL) and radiotherapy complications among Chinese nasopharyngeal carcinoma (NPC) patients at different 3-dimensional conformal radiotherapy (3DCRT) stages adjusting for other variables. Methods: 511 NPC patients at different 3DCRT stages were enrolled. They were interviewed regarding SF-36, complications and socio-demographic variables and cancer- or treatment-related variables. Analysis of covariance (ANCOVA) based on SF-36, complications scores as dependent variables, 3DCRT stages as independent variables, and other variables as covariate were established. Results: The influencing factors of PCS included 3DCRT stages and age group. The influencing factors of MCS included 3DCRT stages and income. Most QOL scores of NPC patients were significantly associated with 3DCRT stage, after accounting for other variables. QOL scores of the patients receiving 3DCRT were the lowest, QOL scores of people after 3DCRT gradually increased. PCS scores of people greater than 5 years after 3DCRT was improved to or even better than the level before 3DCRT. The complications with significantly different scores of patients at different 3DCRT status included xerostomia, throat ache, hypogeusia, caries, hearing loss, snuffles. Conclusions: Clinicians should pay more attention to older NPC patients and patients with lower income. When patients receive 3DCRT, measures should be taken to reduce radiation injury to improve the patients' QOL.

Purpose: Fibrillar collagens like type I collagen, are the major constituent of the extracellular matrix and structural protein of bone. Also, it can be a scaffold for osteoblast migration. The purpose of this study is to estimate the effects of absorbable atelo-collagen sponge (Teruplug$^{(R)}$, Terumo biomaterials Co., Tokyo, Japan) insertion in tooth extraction sites on periodontal healing of the second molar, healing of the fractured mandibular bone and new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Methods: In our study of six cases of mandibular angle fractures, all of them underwent the extraction of the third molar tooth & absorbable atelo-collagen sponge insertion in tooth extraction site. Three of them had a intraoral infection & oral opening to fracture site, two of the six had dental caries, and only one had reduction problem due to third molar position. Six consecutive patients with noncomminuted fractures of the mandibular angle were treated by open reduction and internal fixation using one noncompression miniplates and screws placed through a transoral incision. Results: All of the patients have showed good postoperative functions and have not experienced complications requiring second surgical intervention. There was well healing of the mandibular bone and the most new bone formation of third molar socket after the extraction of the impacted third molar with mandibular angle fracture. Conclusion: The results of this study suggest that absorbable atelo-collagen sponge is relatively favorable bone void filler with prevention of tissue collapse, food packing, and enhance periodontal healing. Thus, the use of atelo-collagen sponge and one noncompression miniplate seems to be relatively easy, safe, and effective for the treatment of fractures of the mandibular angle and third molar extraction.

Objectives : Because elementary school children are sensitive and prevalent to dental caries, oral health care program for the elementary school children (ESOHCP) should be met the first priority for the national oral health care program. This study was performed to proposed the guidelines for executing the efficient ESOHCP through the evaluation of present oral health care and education status based on the attitudes and opinions of health teachers. Methods : Subjects were 181 health teachers those are a part of the total 273 elementary school health teachers in Busan. From April to June 2001, questionnaire survey on the teacher's attitude and opinion, present status of oral health care and education in their own school was done. Data was analyzed by $\chi^2$-test, t-test, ANOVA using SAS (ver 6.21) program. Results : Mean age of the teachers was 40 years (24~58 years) and mean scale of the subject school was 32 classes (5~58 classes). Above 90% of them agreed with the necessity and importance of ESOHCP, but actual level of concerning was lower. They gained the informations about oral health mainly from media (33%), PC net (26%), academic society (25%), and more used internet (p=0.012) in younger generation. Though most of them (96%) had a specified school dentist, only 58% had the experience of periodic oral health examinations in their own school. The major experienced ESOHCP was fluoride brushing and contest to choose the best healthy teeth. Oral health education given by the teachers was not professional but their own. About half (42%) of the teachers had never taken education during last one year. Major education materials were VTR tape (79%), teeth model (64%), CD (55%), booklet (50%), etc., and the teachers' preference was also VTR tape (43%) and CD (41%). When they need education materials, they frequently request to dentist's association (36%), academic society (35%), but rarely to dental clinics or dentists (6%). They prefer that two times (46%) of annual oral health education, with the contents of regular brushing (53%), but lower regular visit to clinics (13%). The interest to oral health care (p=0.016) increased with teacher's age. And, they agreed regular students education in case of higher interest(p=0.044). Intention about join in the model school program was decreased with scale of school (p=0.002). Conclusions : This result showed that the present status of ESOHCP is still insufficient. It considered that the health teachers' interest and role is most important for the maintenance and success of ESOHCP. The professional and efficient education program would be focused on the health teachers to induce drive on ESOHCP.

This study was designed to determine the most effective concentration of fluoride and levels of laser irradiation for the remineralization of decayed teeth. After irradiation with a pulsed Nd:YAG laser and the topical application of fluoride, phosphate and fluoride concentration in enamel were measured. And then the changes on surface enamel using an scanning electron microscope were observed. Samples by extraction healthy, permanent, mandibular bovine teeth with no caries were obtained. Among them 371 healthy samples were selected and artificial carious lesions were made. 20 samples were assigned to each experimental group. After irradiation with a pulsed Nd:YAG laser with total energy densities of 10J/$\textrm{cm}^2$, 20J/$\textrm{cm}^2$ for each group. On the teeth, 2% NaF, 1.9% NH4F, 1.6% TiF4 Elmex gel(amine fluoride) and 1.23% APF gel were applied. After pH circulatory procedures, concentrations of fluoride with and Ionalyzer (Orion Research, Model 901, USA) and phosphates with an Uv/V is spectrophotometer (Uvikon 860, Kontrom Co, Switzerland) were measured. By etching the teeth in layers and measuring fluoride concentrations, a profile of fluoride penetration according to depth could be developed. And also the changes on the surface of the enamel using an electron scanning microscope were observed. The comparative analysis yielded the following results : 1. Phosphate concentration was low in all groups compared with the control group except for teeth treated Elmex gel, irradiated with 10J/$\textrm{cm}^2$ and 30J/$\textrm{cm}^2$ energy densities. Teeth treated with APF gel and 30J/$\textrm{cm}^2$ irradiation gad the lowest phosphate concentration. 2. Among all groups, fluoride concentrations in tooth enamel were highest in APF gel and NaF groups irradiated at 30J/$\textrm{cm}^2$. The APF gel group had the highest fluoride concentrations across all energy densities. 3. In the APF gel group, and the NaF group, the greater the energy density of the laser, the higher the fluoride concentrations in the enamel. 4. In all groups, the concentration of fluoride in the enamel by depth tended to decrease with depth. 5. Under the scanning electron microscope, under the condition of irradiation with 20J/$\textrm{cm}^2$, enamel crack was detected for the first time. In the NH4F group, spherical deposits were found on the surface of the enamel, and in the TiF4 group the surface of enamel was covered with an irregular, thin membranous mass in places. In the APF gel and NaF groups irradiated with 10J/$\textrm{cm}^2$, spherical and irregular particles covered the teeth. When these groups were irradiated at 20J/cm2, they were covered with amorphous crystals. These results suggest that one could obtain more effective anticariogenic effects without damage to teeth when less than 20J/$\textrm{cm}^2$ energy densities and APF gel are used.

In order to obtain the basic data concerning the optimal lasing conditions in using Nd:YAG laser as an adjunctive modality of periodontal therapy of root planing without irreversible structural deterioration of cervical cementum, the author selected 36 human teeth having no cervical abrasion and caries (; 12 anteriors, 12 premolars. 12 molars) extracted due to periodontal diseases, and divided them into 4 groups as Group I, II, III and IV (; each group of 3 anteriors, 3 premolars, 3 molars), and prepared a cementum specimen with thickness of $1.0mm{\pm}0.2mm$ sectioned longitudinally at the middle of mesio-distal thickness (; Group I) or horizontally at 1mm-2mm below the cemento-enamel junction (; Group II, III, IV) from each tooth of each group by low speed diamond wheel saw, and treated them with 0.5 M ethylene diamine tetraacetic acid (; EDTA, pH=7.4) for 2 minutes for elimination of remnants during tooth-sectioning. And the author applied the laser energy from a fiberoptic delivered, free running, pulsed Nd:YAG laser (; wavelength 1064nm. pulse duration $120{\mu}sec$, fiber diameter $320{{\mu}m}$) to cementum surfaces in triplicates of one experiment under the following lasing conditions: 1. stationary mode of fiber in contact to cementum surfaces without air-spray (; Group I )/with air-spray (; Group II), 2. unidirectional moving mode of fiber in contact to cementum surfaces under speed of 3mm-4mm/sec without air-spray (; Group III)/with air-spray (; Group IV), 3. energy per pulse (mJ/pulse) [; energy density ($J/cm^{2}$)] in order of 1.0W/10Hz (100J/pulse); $124J/cm^{2}$, 0.5W/10Hz (50mJ/pulse); $62J/cm^{2}$, 0.4W/10Hz (40mJ/pulse); $50J/cm^{2}$, 0.3W/10Hz (30mJ/pulse); $37J/cm^{2}$, 4. exposure time of 1 second. And the author applied the platinum coating on surfaces of cementum specimens, and evaluated the characteristics of ultrastructural change on surfaces of cementum using the scanning electron microscopy. In general the ultrastructural loss of cervical cementum irradiated under the same lasing condition of laser energy density occurred least in specimens of Group IV. And especially, the ultrastructural loss of cervical cementum irradiated under the laser energy density of $37J/cm^{2}$ almost did not occur in specimens of Group IV. Therefore, it is considered that the pulsed Nd:YAG laser should be applied with the lasing conditions of unidirectional moving mode of fiber in contact to cementum surfaces under speed of 3mm-4mm/sec with air-spray and of laser energy density within $37J/cm^{2}$ as an adjunctive modality of periodontal therapy of root planing without irreversible structural deterioration of cervical cementum.

This study was conducted to investigate the health behavior and the oral health status of workers engaged in a manufacturing business, and to analyze the related factors that affect their number if teeth loss. References for the study involved the materials of 526 individuals whose occupational categories are of a manufacturing business, amongst the survey participants in seven city or gun (county) area including Gyeongsan-si, Gyeongju-si, Mungyeong-si, Chilgok-gun, Yecheon-gun and Sangju-gun for the Community Health Survey (CHS) conducted in 2008. The CHS 2008 was conducted for three months from September to November 2008, and the survey details utilized in the study included the number of loss of teeth and teeth-brushing frequency, which was a part of CHS questionnaires and also additionally included for the study. The analysis with respect to the number of teeth loss on sociodemographic factors, was found to be significantly related to the age, educational status, average monthly income and occupation (p<.01). In the $x^2$-test in terms of the oral health status and the number of teeth loss, it was found that the teeth-brushing after lunch (p<.05) and an experience in an oral examination were statistically significant factors (p<.01). According to the multiple-regression analysis with the number of teeth loss being a dependent variable, the age, educational status, marital status and subjective oral health status were the statistically significant (p<.01). In conclusion, it is important to provide education on the teeth-brushing subjected to workers engaged in a manufacturing business with many dental caries and low educational status, and to recommend a regular scaling as well as to establish policy for creating conditions upon an oral health check-up and a tooth scaling and thus allow the maintenance of an oral health.
