Objectives: The purposes of this study were to comprehend the subjective dental health status and the level of dental health knowledge in some middle school students and to analyze the correlation with dental health behaviors. Methods: A survey was conducted in some middle school students and the final 637 survey data were analysed. As the statistical analysis methods, the subjective dental health status, dental health knowledge and dental health behaviors according to the general characteristics were analyzed by independent t-test, one way ANOVA and Scheffe. The correlations among the subjective dental health status, dental health knowledge and dental health behavior were found by Pearson's correlation and multiple regression analysis. Results: Through correlation analysis of the subjective dental health status, dental health knowledge and dental health behavior, all showed a significant correlation. As a result of the factor analysis affecting dental behaviors, subjective dental health status was the highest (${\beta}=0.304$, p<0.001). Conclusions: The results of this study suggest that the improvement of subjective dental health status and dental health knowledge related to dental behaviors health in the middle school students should be considered. In addition, dental health education should focus on improving subjective dental health status through motivation rather than knowledge transfer training. Moreover, development programs appropriate for the middle school students whose behavioral changes are hard to obtain are needed.

Objectives: The purpose of this study was to investigate nail hygiene behaviors and to identify the relationship between hand hygiene beliefs and nail hygiene behaviors among dental hygienists, dental's aide and dental coordinator in South Korea. Methods: The subjects were 291 dental workers including dental hygienists, dental assistant and dental coordinator working full-time at dental clinics, dental hospitals, general dental hospitals and dental university hospitals in Seoul, Incheon, and Gyeonggi-do. The questionnaire consisted of a total 35 items, including 4 items on general characteristics, 25 items on hand hygiene, 2 items on "nail art" experience, and 4 items on nail hygiene behaviors. The collected data were analyzed using an independent t-test, one-way ANOVA, chi-square test, correlation analysis, and multiple linear regression analysis, where ${\alpha}<0.05$ was considered statistically significant. Results: The scores of behavioral beliefs, normative beliefs, control beliefs and nail hygiene behaviors were $5.15{\pm}0.58$, $5.26{\pm}0.81$, $3.69{\pm}0.96$ and $5.03{\pm}0.98$, respectively. Statistically significant relationships were detected in terms of participants' clinical experiences with respect to behavioral and normative beliefs (p<0.05 for all three belief categories). Participants working in general dental hospitals and dental university hospitals demonstrated the highest scores for behavioral, normative and control beliefs (p<0.05). Participants working in dental clinics reported the highest "nail art" experience rates in the last two years (45.5%) and at the time of the survey (15.7%; p<0.05). Nail hygiene behaviors were more likely to be observed in individuals with stronger behavioral and stronger normative beliefs (p<0.05). Conclusions: More specific infection control guidelines for "nail art" among dental workers should be established and promoted, so that both patients and dental workers can interact in a safe environment.

Background: This study analyzed the practice of dental medical dispute prevention rules of dental hygienists to present an improvement plan for improving perceived importance and practice and provide data for the development of effective medical dispute prevention programs. Methods: A self-administered questionnaire survey was conducted targeting dental hygienists who were providing assistance at dental hospitals and dental clinics in Seoul and Gyeonggi-do regions from March 22 to April 28, 2022. The questionnaire collected from 273 dental hygienists consisted of eight questions on general characteristics, 30 questions on medical dispute experience, and 14 questions on medical dispute prevention. Results: Complaints showed a high experience rate in 'Consultation & reservation', medical disputes in 'Patient handling (unkind) related', and 'Prosthesis installation and cement removal'. In both the importance and practice of medical dispute prevention rules, 'Preservation of medical records and other medical-related data' was high, and 'Management of patients on standby for a long time' was low in terms of practice. 'Lack of time' and 'Lack of manpower' were cited as reasons for not resolving dental treatment disputes. The importance of dental dispute prevention rules was found to be significant according to age and position, and it was also found to affect the level of practice. Conclusion: Seventy-six-point six percent of the respondents said that education on the prevention of medical disputes was necessary, although they lacked recognition of prevention rules compared to their perceptions and experiences. This study suggested specifying prevention rules in dental hygiene subjects and expanding education, improvement of dental treatment system, revise the law on the range of work to improve the recognition and practice of prevention rules.

The purpose of this study was to serve as a basis for the planning of oral health education and the development of an oral health-promotion program for patients who visited dental clinics by examining how much dental hygienists offered oral health education to adult patients at dental clinics. A parent group was selected, being made up of 1,600 dental hygienists who registered with the Dental Hygienist Association and worked in Seoul. The questionnaire survey was carried out and an ${\chi}^2-test$ was made using the data collected from 218 subjects to determine how their practice of oral health education was different according to certain general characteristics(the sort of organization for which they worked, age, the term of their service, and the mean number of patients per day). As a result, the following findings were obtained: 1. Thees general characteristics made the following differences to the content of oral health, education: The sort of organization for which the subjects worked made a significant difference in the following tooth brushing instruction (p<0.05), the effect of oral prophylaxis or education about aftereffects (p<0.05), the regular examination of prosthesis (p<0.05), smoking-prohibition education (p<0.05), and the prevention poor-quality fillings (p<0.01). The mean number of patients per day made significant differences to the regular examination of prosthesis (p<0.05) and the prevention poor-quality fillings (p<0.01). But no significant disparity was generated by age or the term of service. 2. The general characteristics made the following differences to education about nutrition and diet counseling: The sort of organization for which the subjects worked had a significant effect just on the importance of a balanced menu (p<0.05). Age made significant differences in advice for vitamin, mineral, protein or other nutrients (p<0.01), and the importance of balanced menu (p<0.001). The term of service made significant differences in the importance of balanced menu (p<0.01), and advice for nutrients including vitamin, mineral or protein (p<0.01). 3. The general characteristics made the following differences to the recommendation and use of oral hygiene aids: The sort of oragnization for which they worked made significant differences only to a gingival massager and water pick (p<0.05). No significant difference was produced by age, the term of service or the mean number of patients per day. 4. The use of educational media for oral health was different according to the general characteristics: The use of pamphlets or booklets significantly varied depending on the organization for which they worked and with the mean number of patients per day (p<0.05). The use of slides or slide projectors was significantly affected by age (p<0.05). But no significant disparity was yielded by the term of service. 5. The general characteristics made the following difference as to whether a continued oral management system was carried out or not: The sort of organization for which they worked had very a significant effect on this result (p<0.001), and no significant disparity was made by age, the term of service or the mean number of patients per day. 6. The place where oral health education was giver differed according to the following general characteristics: The sort of organization for which they worked made very a significant difference as to the use of an examination room's dental unit chair or waiting room (p<0.01), and to the use of an oral health education room or reception counter (p<0.001). The term of service had a significant effect on the use of a counseling room (p<0.01). And the mean number of patients per day made significant differences in the use of a dental unit chair or reception counter (p<0.05), and to the use of an oral health education room or waiting room (p<0.01).

An overall reduction in the horizontal and vertical dimensions occurs following tooth extraction and the resorption of the buccal part of the ridge is more pronounced than the lingual part. Thus, the resulting morphology of the healed alveolar ridge is often presenting with a discrepancy in bone height between the buccal and lingual aspects of the ridge. The implant with a sloped marginal configuration that is designed to match the sloped contour of the alveolar ridge provides the opportunity to maintain the buccal-lingual bone discrepancy and soft tissue around the implant. This paper introduces the OsseoSpeed TX Profile implants with sloped marginal configuration and explains the characteristics and clinical meanings of those implants.

Titanium implant is used as the most popular dental material for replacement of missing teeth recently. A lot of studies on the surface modification of titanium implant have been carried out for enhancing osseointegration. The surface modification techniques could be classified as follows; topographic modifications which provide roughness and porosity, chemical surface modificationss or deposition of osseoconductive materials, and biochemical modifications to immobilize bone growth factors on titanium surface. In this study, the current and ongoing surface modification techniques and its typical characteristics used in clinics were reviewed. In the future, study and implication about biochemical modifications including patient' s individual characteristics will be important.

Objectives: The purpose of the study was to investigate the related factors to dental fear in some adults. Methods: A self-reported questionnaire was filled out by 320 adults in Seoul and Gyeonggi-do from April to June, 2013. Except 14 incomplete answers, data were analyzed by SPSS 18.0 program. The questionnaire consisted of general characteristics of the subjects(7 questions), dental fear related factor(18 questions), distrust for dentist(15 questions), and distrust for dental hygienist(11 questions). The instrument for dental treatment fear was Dental fear Survey(DFS) adapted from Kleinknecht and partly modified by Choi. Out of 20 questions, 18 questions were reconstructed and score by Likert 5 scale. Higher score means higher dental fear. Cronbach alpha was 0.959 in the study. The distrust for dentist and dental hygienist was adapted from Choi and reconstructed and score by Likert 5 scale. Higher score means higher distrust for dentist and dental hygienist. Cronbach alpha was 0.937 in distrust for dentist and 0.874 in distrust for dental hygienist in the study. Results: Those who experienced dental pain tended to have dental fear. The reasons for dental fear were as follows; bad breath(2.96 out of 5 points, hereafter represented as of 2.96/5), dental caries(2.88/5), missing teeth(2.87/5) and tooth pain(2.77/5). The distrust for the dentist was the main dental fear in the adults. Conclusions: The dental fear was closely related to gender, experience of dental pain, oral symptoms and distrust for the dentist. As the psychological pain in the patients was mainly influenced by the trustful atmosphere, it is necessary to make the patient easy before treatment.
