The odontogenic keratocyst (OKC) was originally classified as a developmental cyst, and OKC is histologically divided into orthokeratic and parakeratic types. According to revised histopathological classification of odontogenic tumors by the World Health Organization (2005), the term, keratocystic odontogenic tumor (KCOT) has been adopted to describe parakeratic OKC. The KCOT is noted for its capacity to recur after treatment. The aggressive, or potentially aggressive, nature of KCOT has led to alternative treatments. Among the treatments is noted the use of Carnoy's solution as adjunctive intralesional therapy having a low rate of recurrence. This study suggests a possible benefit of Carnoy's solution against recurrence of KCOT.

The purpose of this study was to examine the oral health state of the elderly in an effort to pave the way for dental health project planning for the elderly for the city of Jeonju and to help promote the oral health of the elderly population to which health care services weren't accessible a lot. The subjects in this study were 300 elderly people who were in their 60s and up and used 10 different welfare establishments for the elderly in Jeonju. A survey was conducted from May 3 through 13, 2005, by interviewing them in person, and the collected data were analyzed. The findings of the study were as follows: 1. In terms of the period of oral health examination, 44.1 percent of the 66-70 age group, 48.1 percent of the elementary school graduates and 39.4 percent of the house owners had their teeth examined whenever they had a toothache. So their cycle of oral health examination was statistically significantly different according to age(p<.05), education(p<0.001) and form of residence(p<0.001). 2. Regarding the necessity of prosthesis, prosthesis was needed by 52.1 percent of the age group from 71 to 80, 44.3 percent of the women, 48.9 percent of the men, 60.0 percent of the community college graduates and 55.9 percent who rent a house on a deposit or monthly basis. But there was no statistically significant gap among the groups. 3. As for the necessity of oral health education, the necessity of it was absolutely supported by 89.7 percent of the 66-70 age group, 76.0 percent of the women, 87.2 percent of the men, 95.3 percent of the middle school graduates and 87.7 percent of the house owners. Their age(p<.0.01), gender(p<0.05) education(p<0.05) and form of residence(p<0.01) made a statistically significant difference to that. 4. Concerning oral health education experience, 79.3 percent of the high school graduates and 79.8 percent of the house owners had never received oral health education, and that experience statistically significantly varied with education(p<0.001) and form of residence (p<0.001). 5. As to the biggest reason for oral health care, 50.0 percent found it necessary to take care of their teeth to ensure their own perpetual oral health, and 33.7 percent felt the need for that because they had a toothache. The above-mentioned findings indicated that the elderly people were definitely in want of oral health education. Dental hygienists in public dental clinics should serve as dental health educators to address their needs, and regular oral health care programs should be prepared to spread awareness about the importance of oral health among elderly locals.

Areca nut (AN) chewing is a habit in many countries in Central, Southern, and Southeast Asia. It is strongly associated with the occurrence of oral, pharyngeal, and esophageal cancer as well as systemic inflammation. However, the association between AN intake and the development of gastric lesions has not yet been identified. The aim of this study was to investigate the effect of AN on gastric diseases using a mouse model for Helicobacter pylori infection. We studied four groups of mice: those fed a normal diet (ND), those fed a diet containing 2.5% AN (AD), those fed ND and infected with H. pylori PMSS1 strain (ND/HP), and those fed AD and infected with H. pylori PMSS1 strain (AD/HP). Food intake and body weight were monitored weekly during the experiments. At 10 weeks, the mice were sacrificed, and the stomach weight, H. pylori colonization, and gastric inflammation were evaluated. The stomach weight had increased significantly in the ND/HP and AD/HP groups along with increases in H. pylori colonization; however, there was no significant difference between these two groups with respect to stomach weight and colonization. On histological grading, mononuclear cell infiltration was severer in the AD/HP group than in the ND/HP group. These data suggest that chronic gastric inflammation was aggravated by AN treatment in the mice with H. pylori-induced gastric lesions. Furthermore, as previously suggested, this animal model is useful to determine the effect of potential carcinogens on gastric lesions induced by H. pylori infection.

To provide basic data necessary to develop an efficient sealant project as a public oral health project, this study applied a sealant through a photodimerization method to first-graders from public primary schools in the Dong-gu Health Center in Incheon and conducted a survey on favor and knowledge of the sealant project with their parents and, consequently, obtained the following results. 1. 84.7% of the parents knew a sealant and most of them got the knowledge from a dental clinic (35.7%) or a school (31.6%). 2. A large majority of respondents (86.2%) were satisfied with sealant application; many parents (75.8%) checked for maintenance of the sealant; and 75.6% demanded reexamination after sealant application. 3. As factors associated with acceptance of a sealant, high recognition of a sealant, much experience of visiting a dental clinic, and parents' great concern about children's dental health were related to high sealant application. To put the results together, it is desirable to develop the sealant project by the Dong-gu Health Center in Incheon actively as a public oral health project.

Background: The establishment of a strategy for the reduction and prevention of oral disease, a global pervasive disease, is considered one of the important national health policy strategies. In Korea, the 5th Comprehensive National Health Promotion Plan is currently in progress, but there is insufficient research on the transition process or improvement direction in the field of oral health. Methods: Changes in Comprehensive National Health Promotion Plan's Oral health sector in three countries were compared, and the direction of the three countries (Korea, the United States, and Canada) in accordance with the recent Oral health paradigm was confirmed. In this study, we reviewed the existing literature using the narrative review method to draw implications for strategies and directions for oral health promotion in Korea. Results: In Korea, the oral health promotion strategy is included in the 5th Comprehensive National Health Promotion Plan, and the project is being led by the government. The United States prepared a national-led oral health promotion strategy and suggested multi-disciplinary cooperation to improve overall oral health and reduce the oral health inequality. For more active intervention, Canada established an oral health-related department and assigned experts, while emphasizing cooperation between the government and the private sector. Conclusion: As a result of this study, Korea is also making efforts to improve oral health, but more active government intervention is needed to reduce the inequality in oral health by population group. To this end, it is necessary to establish a strong multi-sectoral cooperation system and prepare a strategy for implementation.

Objectives : The purpose of the study is to obtain the basic data for an industrial oral health project enhancing the quality of life and oral health. Methods : Questionnaire consisted of 17 questions including 7 questions of general characteristics, 5 questions of oral health awareness, and 5 questions of the behavior of oral health. A self-reported questionnaire was carried out from September 1 to September 28, 2012, The subjects were 400 male and female sanitation workers in private corporations in Jeonju. A total of 354 questionnaires were analyzed using SPSS windows ver. 12.0 (SPSS Inc. Korea). Results : The majority of the subjects were male in 50's. Temporary contract workers are older aged and 2 to 5 years of career workers were the majority of the cleaners. Average monthly income was less than 2 million Korean Won. Those who had a higher academic background and permanent position tended to have oral health knowledge (p<0.05). Female workers had healthier subjective oral health status than male workers. Those who were in older age, single, temporary position, and 2 to 5 years of career tended to have healthier subjective oral health status (p<0.05). Those who were in older age, married, and long period of employment were worrying about their health (p<0.05). The subjective oral health knowledge was high in 49.7% of the workers because they were not able to brush teeth during work hours. They were able to brush their teeth only after dinner. It was low in female and older aged workers (p<0.05). The brushing method included a combination of top to bottom and from the side to side. Conclusions : This study showed the influencing factor of oral health in street workers. Work environment, education, age, monthly income, and types of employment were the important factors to oral health care. It is necessary to provide the right oral health care program for the workers in the near future.

Purpose: This study was to investigate the types of imaging modalities, analytical methods for age estimation, and the age of the subjects in research on age estimation using dental radiography through a scoping review, and to investigate the overall trends in age estimation studies. Materials and Methods: A scoping review was designed according to the Arksey and O'Malley guidelines and the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Three electronic databases were used as search sources (Medline, Embase, and Cochrane Library). Studies were classified according to the three main components of the research question. "What are the imaging modalities, analytical methods, and target age in dental imaging-based age estimation studies?" Result: The final 198 studies were selected by two reviewers. The most common imaging modality used in studies was panoramic radiography (69.7%), and studies using cone-beam computed tomography have increased over time. Analytical methods for age estimation were 62.6% in studies based on tooth development and 26.3% in studies using pulp/tooth ratio. The subject age was 27.8% for children and 27.3% for adults. Studies conducted in all age groups comprised the smallest category (5.2%). Conclusion: Panoramic radiography has been the most used types of imaging modalities for age estimation, and the most common analytical method was analysis of tooth development. Most studies targeted specific ages, and very few involved all age groups. Dental age estimation studies should be carried out with appropriate consideration of the imaging modality that is analyzed, the methods that are used, and the age that is targeted.
