It is going to select one X-ray generating device for diagnosis in a radiography laboratory at K university in Gangwon-do to detect bacteria on the surface contamination of tables, IP cassettes, and lead gowns for medical radiation shielding and to inform students of the need for proper disinfection control and hand hygiene. Then disinfection was carried out with tissue, tissue cleaner and 70% alchol and immediately collected with sterile cotton swabs to assess the contamination distribution status and disinfection effects of the surface. The results of measuring the degree of contamination on the surface showed that the largest number of bacteria were detected in Apron, and the evaluation of the disinfection effects according to surface contamination showed a noticeable effect at 70% Alcohol in IP Cassette, and the disinfection effect was the same for Apron. Therefore, in order to prevent bacterial infections among students, basic hand washing and regular disinfection should be performed before the practice to prevent infection.

This study aimed to investigate recognition and satisfaction toward Korean herbal foods according to dietary lifestyle as well as the actual status of using ingredients for Korean herbal foods while looking for methods to improve use. The general characteristics of the respondents included relations with foods such as learning or working on them, and the correlations with the examined items were analyzed by grouping according to dietary lifestyle. Five significant dietary lifestyle groups were derived by analyzing the groups using the factor scores from the analysis. Recognition of Korean herbal foods was higher with older respondents and more cooking experience. Regarding experience related to Korean herbal foods, the housewives showed higher satisfaction when the ingredients of foods were bought and cooked. And satisfaction with price differed significantly by dietary lifestyle. With regard to experience of using ready-to-cook or ready-to-eat products, the groups with more cooking experience indicated relatively lower satisfaction with the taste of such products. When visiting restaurants, the groups with less cooking experience showed higher satisfaction with taste and nutritional values. Regarding the actual status of using ingredients for Korean herbal foods, most of the respondents answered that hygiene and quality management, distribution and marketing, and the promotion of ingredients are all essential.

Failure of fixed implant supported prosthesis is caused by biomechanical factors such as excessive occlusal stress and biological factors such as bacterial infections and inflammation. Implants with severe bone resorption that have worsened without being resolved due to implant complications should be removed and then new treatments should be planned, taking into account remaining teeth, remaining implants, and residual alveolar. The patient of this case removed some of fixed implant prosthesis of mandible. The condition of the remaining alveolar bone was reassessed for further implant replacement and a few implants were placed. Then implant assisted removable partial denture (IAPRD) treatment is performed using implant surveyed bridge as abutment. Through this treatment, the clinical results were satisfactory on aspect of masticatory function recovery and oral hygiene management.

Multimodal cancer therapy including surgery, chemotherapy, and radiotherapy could not only improve the prognosis of malignancy but also reduce the dosage and toxicity of cancer drug for treatment of malignant tumor. The effects of radiotherapy are generally localized, additive, and accumulative, and depend on dosage, site and cell sensitivity. However, in growing individuals, the dental and skeletal sequelae to radiotherapy result in dental or facial abnormalities that are irreversible : arrested root development, disturbances in enamel formation, microdontia, anodontia, altered tooth eruption and mandibular or maxillary hypoplasia. Especially, the teeth which are developing is affected according to the stage. We report three cases of developmental disturbance of permanent teeth after radiotherapy. These children had received radiotherapy for malignant tumor at the age of 3 to 4 years, in which root hypoplasia, short tapered root and early apex closure were observed. For the management of radiation caries and radiotherapy-related teeth, periodic recall check and oral hygiene instruction are required.

The dental caries can be recovered or worse depending on the velocity of de- and remineralization of tooth. It is possible to remineralize the lesions by fluoride agent, but the results can be distinguished according to one's salivary flow rate, quantity of ion contents, and pH of the saliva. This article presents good results after applying the CPP-ACP paste for the patients who have incipient enamel caries. We instructed the patients to apply the paste everyday in the customed tray. We observed the white spot lesions without getting worse and reducing the size of lesions. After applying the CPP-ACP paste for 6 weeks, we concluded that; 1. It was possible to remineralize the incipient caries without preparation of the teeth. 2. CPP-ACP paste was successful for recovery of the demineralized lesions, especially for mild and moderate caries lesions, not for the severe developemental defects or chronic lesions. 3. CPP-ACP paste was efficient for pediatric patients, and the custumed tray was very useful for patients to apply the paste. 4. The ability of the patients for caring their oral hygiene was improved by routine check up and instructions.

Lesch-Nyhan syndrome is a rare X-linked, recessively inherited disorder of purine metabolism, caused by complete absence of the enzyme hypoxanthine-guanine phosphoribosyl transferase. This syndrome is characterized by 3 major features: neurological dysfunction, hyperuricemia, and cognitive and behavioral disturbances (e.g., self-mutilation, which begins at 2 to 3 years of age). Uncontrollable self-mutilation begins with biting of the perioral tissues and extends into patterns such as finger biting and head hitting. This report describes the case of a 31-month-old boy who was diagnosed with Lesch-Nyhan syndrome with severe lip injuries caused by self-mutilative behaviors. The behaviors were blocked with a semi-fixed lip bumper for a short period. The device was applied to the patient on the day of the visit without the requirement for an oral impression. It was easy to manage oral hygiene and adjust the device because it was detachable by clinicians and guardians. Therefore, a semi-fixed lip bumper may be useful as an interim appliance to block selfmutilative behaviors in children with Lesch-Nyhan syndrome.

목적 : 본 연구는 업무형태에 따른 측두하악장애의 유병률과 업무 시 노출되는 직무스트레스 및 구강 내 악습관이 측두하악장애와 어떠한 연관성이 있는지 알아보아 보건학적 기초자료를 제공하고자 실시되었다. 방법 : 본 연구의 자료 수집을 위하여 서울과 경기 일부지역에 근무하고 있는 일반사무직, 서비스직, 교직원으로부터 편의 추출된 452명을 대상으로 2010년 1월부터 2010년 4월까지 설문조사를 실시하였고, 수거된 353명을 연구대상으로 하였다. 설문지는 측두하악장애의 증상, 하악사용에 관한 구강 내 악습관, 직무스트레스, 인구사회학적 특성으로 구성되었다. 측두하악장애의 증상의 정도를 구분하기 위해 설문지의 양성응답 수의 빈도에 따라 무증상인 1단계에서 양성응답 수가 가장 많은 4단계 까지 총 4그룹으로 나누었다. 측두하악장애의 유병률을 알아보기 위하여 빈도분석을 시행하였고, 측두하악장애의 증상의 정도에 따른 여러 요인들 간의 연관성 및 관련요인을 알아보기 위하여 교차분석 및 경향성 분석과 다항로지스틱회기 분석을 시행하였다. 결과 : 측두하악장애의 유병률은 75.4%였고, 측두하악장애에 대한 주관적 증상으로는 관절잡음이 56.4%로 가장 주된 증상 중 하나였으나 남녀 간의 차이는 통계적으로 유의하지 않았다. 다음으로는 두통이나 목의 통증이 36.5%이었고, 귀, 관자놀이, 볼 주위의 통증이 22.1%로 높았다. 측두하악장애의 주관적인 증상 수에 따른 인구사회학적 특성은 증상이 없는 경우 여성에서 19.1%, 남성에서 36.6%로 여성에서 더 높은 유병률을 보였다. 연령별로는 40세 이상의 그룹보다 20 - 30대그룹에서 측두하악장애 증상수가 높아지는 경향을 보였다. 하악 사용과 관련된 악습관 및 직무스트레스는 측두하악장애 증상수와 유의한 관련성이 있는 것으로 나타났는데, 하악 사용과 관련된 습관의 개수가 많아질수록 측두하악장애의 증상의 개수도 많아졌고, 습관이 한 가지씩 늘어날수록 측두하악장애 증상이 없는 1단계보다 3단계가 될 위험이 1.45배, 4단계가 될 위험이 1.57배 높아졌다. 스트레스 수준도 가장 하위단계에서 한 단계 높아지면 측두하악장애 1단계에서 4단계가 될 위험이 2.49배, 두 단계 높아지면 3.43배 높아졌다. 결론 : 본 연구의 결과 측두하악장애와 업무특성에 따른 연관성은 설명하지 못하였지만, 직무스트레스가 높은 경우 측두하악장애 증상의 개수 또한 높아짐을 확인할 수 있었다. 이는 측두하악장애의 주관적인 증상을 발생시키는데 있어서 업무형태 보다는 심인적인 부분이 더 중요한 인자임을 의미한다. 그러므로 측두하악장애 평가 시 신체적인 문제뿐 아니라 행동적, 심리 사회적 문제로 예측인자를 폭넓게 인식함으로써 다각적인 접근을 하는 것이 필요하며, 측두하악장애 증상이 발생된 경우 임상적 치료뿐 아니라 행동요법 및 심리 치료와 자가 관리 등이 함께 수반되어 기여요인 조절을 조절하는 것이 중요하다 하겠다.

Objectives: The purpose of the study is to evaluate the effect of continuing dental care program by elementary school dental clinic in Gimcheon from 2008 to 2013. Methods: The subjects were experimental group of 152 students from three elementary schools having dental clinics and control group of 136 students from three elementary schools of no dental clinics. The six dentists in Gimcheon community health center carried out the regular dental checkups in the elementary schools and four dental hygienists recorded the dental examination results. After receiving WHO dental survey guideline education, the examiners used dental mirror and dental probe under the natural light. The contents of the survey included dental caries in the deciduous and permanent teeth, malocclusion, remaining ratio of sealant, treatment, and follow up. Results: DFT index by grade showed that 3.71 in experimental group and 4.56 in control group and it was remarkable in the 3rd grade. Thus. DFT index in the experimental group was lower than that of control group (p<0.05). DT index by grade was 0.63 in experimental group and 1.28 in control group marked in the 6th grade. DT index in the control group was higher than that of the experimental group (p<0,001). DFT index and DMFT Index by grade showed no significant difference between the control group and the experimental group. DFT and DMFT Index of the control group in the 3rd and 6th grade were lower score than those of experimental group. DFT and DMFT index in the third and 6th grade showed no significant difference between the control group and the experimental group. The remaining ratio of the sealant was 4.89 experimental group in the 6th grade. The remaining ratio of the sealant in the experimental group was higher than that in the control group. Conclusions: The continuing dental care program in the elementary school is very effective method in the treatment of oral disease in the elementary school children. The oral health care and prevention for the elementary school children should be implemented and carried out continuously.

Cypress woods treated individually with boric acid (BA4), ammonium pentaborate (APB4), or BA4/APB4 additives were examined for combustion gases. Each of the specimens was painted with a 4 wt% solution of boron compounds three times. Dried at room temperature, the combustion gas was analyzed using a cone calorimeter (ISO 5660-1). Consequently, the second maximum oxygen consumption rate of the specimen treated with boron compounds was 0.1067 to 0.1246 g/s, which was 5.3 to 18.9%, respectively lower than that of the blank specimen. The specific extinction area of specimens treated with BA4 and APB4 was also 2.0 to 19.0% lower, respectively. However, treated with BA4/APB4 showed 21.2% higher than that of the blank specimen. The maximum carbon monoxide concentration of the specimens with boron compounds was reduced by 0 to 25%. It was estimated to be 1.6 to 2.2 times higher than the permissible exposure limits by Occupational Safety and Health Administration (OSHA), indicating a fatal toxicity. The boron compounds were effective in reducing carbon monoxide, but didn't meet the OSHA limit. The boron compound inhibited the burning behavior of the cypress wood, which suppressed the second maximum oxygen consumption rate by 5.3 to 18.9% and the maximum carbon monoxide generation by 0 to 25%.
