The purpose of this study was to evaluate the influence of energy drinks on the erosion of dental enamel and mouse teeth growth. Exposure of enamel surface to energy drinks stimulated the release of the calcium from enamel surface of teeth. And the surface microhardness of enamel decreased after immersion in energy drinks. Enamel demineralization effects under energy drinks were observed by scanning electron microscope. Effect of maternal energy drink intake on tooth morphology of offsprings was analyzed. We concluded that the energy drinks produced a significant erosion of dental enamel.

The purpose of this study was to enhance soldiers' oral health level and to offer basic data on controlling and preventing halitosis. It surveyed halitosis-related elements and analyzed relationship between subjective self-perception level of halitosis according to it targeting 253 soldiers in their 20s in some areas of Seoul from September 2012 to October. Thus, the following conclusions were obtained. 1. As for subjects' self-perception of halitosis, the perception status of oral health was indicated to be 'very bad' and to be shown most highly in one place. It was indicated to be high in the group of feeling Xerostomia much and the group of often feeling the white membrane of tongue. The statistically significant difference was shown(p<0.01). 2. Subjects' self-perception of halitosis was indicated to be the highest in the group with the largest intake of snacks. It was shown to be the highest in the group of having sinus infection and rhinitis. It was indicated to be the highest in the group of having a habit of oral respiration. Significant difference was shown(p<0.05). 3. Subjects' self-perception of halitosis was indicated to be lower in the group, which ever received oral health education, than the group in opposite case. Significant difference was shown(p<0.05).

In the field of oral-maxillofacial surgery, vascular malformations present in various forms. Abnormalities in the size of the tongue by vascular malformations can cause mandibular prognathism and skeletal deformity. The risk in surgical treatment for patients with vascular malformation is high, due to bleeding from vascular lesions. We report a rare case of macroglossia that was treated by partial glossectomy, resulting in an improvement in the swallowing and mastication functions in the patient. A 25-year-old male patient with severe open-bite and mandibular prognathism presented to our department for the management of macroglossia. The patient had a difficulty in food intake because of the large tongue. Orthognathic surgery was not indicated because the patient had severe jaw bone destruction and alveolar bone resorption. Therefore, the patient underwent partial glossectomy under general anesthesia. There was severe hemorrhaging during the surgery, but the bleeding was controlled by local procedures.

Objectives: This case report examines the effects of traditional Korean medicine for unspecified tremor with xerostomia caused by psychometric drug intake. Methods: A patient who suffered from unspecified tremor with xerostomia caused by psychometric drug intake was treated with acupuncture, pharmacopuncture, and traditional Korean medicine for 30 days. We provided the patient with herbal medicines including Ondam-tang-gagam (溫膽湯加減), Pumsimgieum-gagam (忿心氣陰加減), and Hoichunyanggyeok-san-gami (回春凉隔散加味). Symptoms were charted and evaluated using the Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale. Results: After treatment with Korean Medicine and pharmacopuncture, the frequency and degree of tremor has decreased, and degree of Xerostomia also improved. The Scores of Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale were also improved. And we could see reduction in the level of distribution of gastrointestinal heat at Digital Infrared Thermal Imaging test. The patient's Symtoms (Xerostomia as well as unspecified tremor) were improved after treated with Korean Medicine and pharmacopuncture. Conclusion: Korean medicine treatments may be valuable for xerostomia caused by psychometric drug intake.

Subacute toxicities of DWH-Ol(Ranitidine : Bismuth : Sucralfate=1.5:2:6) were inverstigated in Sprague-Dawley rats. After oral administration of DWH-01 with different dosages of 5 g/kg, l g/kg, and 0.2 g/kg, we examined the number of deaths, general signs, food intake, water intake, body weight and histopatholgical changes for both sexes of rats. During the adminstration period, urinalysis and opthalmological examination were also performed in the treated animals. 1) Animals were all survived for 4 weeks. 2) There were no significant differences in pathological and opthalmological findings between the control and treated animals. 3) There were no significant changes in body weight, food intake and water intake compared with control group. 4) In hematological examination and blood chemical analysis, there was no significant change compared with control group. 5) In histopathological examinations of organs and tissues, there was some hemorrhage in a lung tissue of low dose group, but it was thought to be caused by environmental factor. These data suggest that DWH-01 is not subacutely toxic in Sprague-Dawley rats.

One of the most serious complications after head and neck radiation is osteoradionecrosis (ORN) of the jaw. The etiology of ORN is extraction, minor dental procedure or dental implant surgery. When ORN of the jaw progressed to stage III, free fibular flap is the most useful methods for reconstruction. In this case report, a 67-year-old ORN patient who underwent fibular free flap reconstruction using simulation surgery with 3-dimensional rapid prototype (3D RP) model was reviewed. After partial mandibulectomy, a osteocutaneous fibula flap was used for reconstruction. Oro-cutaneous fistula was resolved after operation. Patients reported improved food intake after operation without pus discharge. Functional and esthetic results showed successful reconstruction.

The most critical health effect of lead exposure is the neurodevelopmental effect to children caused by the increased blood lead level. Therefore, the endpoint of the risk assessment for lead-contaminated sites should be set at the blood lead level of children. In foreign countries, the risk assessment for lead-contaminated sites is conducted by estimating the increased blood lead level of children via oral intake and/or inhalation (United States Environmental Protection Agency, USEPA), or by comparing the estimated oral dose to the threshold oral dose of lead, which is derived from the permissible blood lead level of children (Dutch National Institute for Public Health and the Environment, RIVM). For the risk assessment, USEPA employs Integrated-Exposure-Uptake-Biokinetic (IEUBK) Model to check whether the estimated portion of children whose blood lead level exceeds 10 µg/dL, threshold blood lead level determined by USEPA, is higher than 5%, while Dutch RIVM compares the estimated oral dose of lead to the threshold oral dose (2.8 µg/kg-day), which is derived from the permissible blood lead level of children. In Korea, like The Netherlands, risk assessment for lead-contaminated sites is conducted by comparing the estimated oral dose to the threshold oral dose; however, because the threshold oral dose listed in Korean risk assessment guidance is an unidentified value, it is recommended to revise the existing threshold oral dose described in Korean risk assessment guidance. And, if significant lead exposure via inhalation is suspected, it is useful to employ IEUBK Model to derive the risk posed via multimedia exposure (i.e., both oral ingestion and inhalation).

Objectives: The aim of this study is to analyze the differences in factors related to the incidence of dental caries between children in fluoridated and non-fluoridated areas and compared the DMFT and DMFS scores to confirm the effect of water fluoridation program (WFP) in Geoje and Changwon. Methods: The oral health examination and questionnaire survey were conducted in fluoridated and non-fluoridated areas. The number of surveyed children aged 8, 10, and 12 years in the fluoridated and non-fluoridated area of two cities was 1,524 and 1,383, respectively. Self-recorded questionnaires included self-perception of their own dental health, daily toothbrushing frequency, intake frequency of cariogenic sweet snacks and beverages, experience of gingival bleeding, experience of unmet dental treatment, and use of oral hygiene device except for toothbrush and toothpaste. The prevalence of caries and fissure-sealant status were surveyed. The logistic regression analysis was used to analyze the difference in children's self-rated oral health status between the fluoridated and non-fluoridated area. The mean number of sealed teeth and surfaces, marginal means of the DMFT and DMFS scores adjusted for the difference in the samples' sex distribution, and region were compared between the fluoridated and non-fluoridated areas. Results: In the fluoridated area, the experience rate of unmet dental treatments was higher among children aged 10 years, intake frequency of cariogenic sweet snacks and beverages were higher among the whole sample, and experience rate of professional fluoride application were lower than in the non-fluoridated area. The DMFT score for permanent dentition adjusted for differences in sex, region, and mean number of fissure-sealed teeth in the fluoridated area was significantly lower among whole samples and 8-, 10-, and 12-year-olds alone than in the non-fluoridated area. Conclusions: WFP can alleviate oral health inequality because it is effective in reducing the incidence of caries among children is disadvantaged demographic, socioeconomic, and cultural contexts.

The purpose of this study is to investigate the actual state of beverage consumption, oral health concern, and oral health behavior among high school students in Daegu and Gyeongbuk. The results of the study showed that the subjects with the highest academic achievement score of 3.46(${\pm}0.43$) were 3.23(${\pm}0.59$), which was statistically significant(F=3.601, p<0.05). Oral health behaviors were 3.16 points(${\pm}0.40$) when the academic performance was 'low', which was significantly different from those of 'high' and 'middle' students(F=4.329, p<0.05). Further research is needed to clarify various related factors related to future drink ingestion and oral health behavior, and it is thought that it is necessary to continue to promote the relationship between beverage and oral health through the results of this study.
