Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.

The purpose of this study is to evaluate oral health status, caries-inducing bacterial activity of the mental retardation students, and developing motivation method for improving oral hygiene management by clarifying the relationship between caries-inducing bacterial activity and oral health status of mental retardation students. Caries experience indices, caries susceptibility test, gingival health evaluation, and oral hygiene management and oral health survey were performed. Results were as follows : 1. The DMFT index of disabled students(12 years) was 2.07. 2. The gingival inflammation was occurred more frequently in older ages. 3. There also was a high positive correlation between caries incidences and the results of caries-inducing bacterial activity test especially in deciduous teeth. This result suggested that the Dentocult SM mutans test as a caries activity test is a reliable method for measuring the status of dental caries in mental retardation students. Because it would motivate the mental retardation students to care more actively for their oral hygiene if they learn how much dental caries-inducing bacteria are living in their mouth by observing the bacterial colony on the cultured test strip, it can become a possibly efficient educational tool for the mental retardation students.

The purpose of this study was to evaluate the efficacy of the newly-developed $Qraypen^{TM}$ (All In One Bio, Korea) system for the diagnosis of early proximal caries by comparing it with the conventional methods of visual inspection and periapical radiography. This study was carried out from July 2015 to April 2016 targeting 32 children aged 7~12 years who visited Y-Dental Clinic for school oral health examinations. Two investigators selected and examined a total of 153 primary molars that had not undergone restorative treatment. Comparisons were carried out between visual inspections, readings of posterior periapical radiography images, and readings of $Qraypen^{TM}$ images. This study revealed that the percentage of interproximal surfaces of primary molar teeth without caries incidence was 83.7% using $Qraypen^{TM}$ imaging and 84.9% using visual inspection and periapical radiography. The differences between the two methods were not statistically significant. Thus, $Qraypen^{TM}$ is expected to be a useful and convenient auxiliary diagnostic device that can facilitate the detection of hidden proximal caries in primary molars.

This study investigated the current oral health conditions of the elderly at home and welfare facilities in their age over 65 years around some rural areas in Gangwon province, which would expect the fewer medical benefits even with lower interest than urban areas, despite of relatively high ratio of elder populations, so that it could prepare a basic document necessary to determine certain planned quantification for the benefit of elder's oral healthcare. As of the end of December 2004 both 50 elders at home and 50 elders at welfare facilities were randomly sampled in their age over 65 years in Samcheok city. As a result of this study, it was found that the elders at welfare facilities scored 15 pts. in DMFT index level typical of oral health conditions, which was higher than the elders at home. In addition, the elders at welfare facilities scored 26.0% in the coexistence of immobile bridge and partial denture higher than the elders at home with regard to the presence of intraoral prosthetic appliance. The results of analyzing the difference in the one-year dental visiting experience of respondents hereof showed that the elders at home were relatively more in ratio(62.0%) than those at welfare facilities, while many of the former group(38.0%) had relatively more handicap in masticatory movement than the latter one with regard to the conditions of dental prosthesis in use. Besides, many of the elders at facilities(30% or more) felt subjective symptoms of periodontal disease including bleeding or swelling, which indicates higher ratio than the elders at home. Finally, the elders at home used to brush their teeth at more frequency on a daily basis than those at facilities, while the latter group suffered general body disease more than the former group. Summing up, it is concluded that a formulated oral healthcare system will become more needed in near future than now for the benefit of the elderly living in welfare facilities, while nationwide policy-level supports would be urgent for them in the aspect of national welfare.
