This study aimed to evaluate the effects of a community-based oral hygiene service on general and periodontal health indicators of patients with hypertension and type 2 diabetes mellitus visiting a community health centre in Korea. The study used a one-group pretest-posttest and interrupted time-series design. A total of 151 participants (45% male), with a mean age of 63 ± 8.4 years, were included in the study; these included patients with hypertension (62%), diabetes (12%) and both hypertension and diabetes (26%). Two dental hygienists dedicated 2 days per week to this project, providing oral hygiene services to 10-13 participants per day. Four oral hygiene service sessions were provided per patient. The objective oral hygiene status and subjective self-reported periodontal status were compared before and after the service. The changes in blood pressure and glycosylated haemoglobin levels were also assessed. A lower frequency of subjective swelling was reported at the fourth session (37.9%) compared to the first (55.6%) session. Further, significantly fewer cases of calculus and bleeding were observed (p < .05), and significantly more patients reported having no gum problems at the fourth session (43.1% vs. 27.2%; p < .05) than at the first session. Finally, the participants maintained stable blood pressures at each of the four sessions, and their glycosylated haemoglobin levels were significantly lower at the fourth session. In conclusion, the findings of this study suggest that community oral hygiene services provided by dental hygienists can promote objective oral hygiene and subjective periodontal status in the local community, and may help in the control of hypertension and diabetes.

The purpose of this study is to propose learning objectives in social dental hygiene by analyzing and reviewing learning objectives in oral health administration area of the existing public oral health. This study is a cross-sectional study. The subjects of the study selected with convenience extraction were 15 members of the social dental hygiene subcommittee of the Korean Society of Dental Hygiene Science. Data collection was conducted by self-filling questionnaire. The research tool is from 48 items of A division in the book of learning objectives in the dental hygienist national examination, and this study classified each of them into 'dental hygiene job relevance', 'dental hygiene competency relevance', 'timeliness', and 'value discrimination of educational goal setting' to comprise 192 items. Also, to collect expert opinions, this study conducted Delphi survey on 7 academic experts. Statistical analysis was performed using the IBM SPSS Statistics ver. 23.0 program (IBM Co., Armonk, NY, USA). Recoding was performed according to the degree of relevance of each learning objective and frequency analysis was performed. This study removed 18 items from the whole learning objectives in the dental hygienist national examination in the oral health administration area of public oral health. Fifteen revisions were made and 15 existing learning objectives were maintained. Forty-five learning objectives were proposed as new social dental hygiene learning objectives. The topics of learning objectives are divided into social security and medical assistance, oral health care system, oral health administration, and oral health policy. As a result of this study, it was necessary to construct the learning objectives of social dental hygiene in response to changing situation at the time. The contents of education should be revised in order of revision of learning objectives, development of competency, development of learning materials, and national examination.

Objectives:The purpose of the study is to evaluate the contents analysis of the community dental hygiene practice in the dental hygiene students and suggest the outcome based evaluation index of community dental hygiene practice. This study will provide the basic data for the community nursing and social welfare practice. Methods: A self-reported questionnaire was completed by 82 dental hygiene professors and 254 dental hygienists in community health centers after receiving informed consent based on institutional review board from 5th Dec 2014 to 30th Jul 2015. A total of 49 professors and 134 dental hygienists gave the complete answers. The study instrument was adapted from the literature review. The questionnaire consisted of evaluation, purpose of evaluation, and evaluation format. Data were analyzed using SPSS 20.0 program. The contents analysis was carried out through input, process, output, and outcome. Results: The practice outcome evaluation was conducted in 62.9% of the dental hygiene departments and 32.9% of the community health centers. Most of the dental hygiene professors chose "To know what students learned(27.3%)" and "To ensure student's role and behavior in practice(27.3%)." as the purpose of evaluation. The public dental hygienists chose "To score the practice grade(42.1%)." The evaluation method was done anonymously. Conclusions: The outcome based evaluation in community dental hygiene practice was the best method to evaluate the practice education for the competency of the dental hygiene students.

Objectives: To evaluate the Community-Based Participatory Research (CBPR) professional periodontal care program model for patients with hypertension and diabetes. Methods: This descriptive case study included 151 participants of the professional periodontal care program. The CBPR-based professional periodontal care program consists of 5-steps: 'Issue identification and prioritization' (Step 1), 'Strategy development' (Step 2), 'Entry into community' (Step 3), 'Implementation' (Step 4), and 'Transition' (Step 5). Quantitative data were analyzed using frequency analysis, and descriptive data with PASW 23.0 (SPSS Inc., Chicago, IL, USA). The results of the Focus group interview (FGI) were classified as 'general opinions regarding the program planning and operation receptiveness', 'sustainability', 'potential spread of the program', and 'improvement of program'. The interviews were qualitative research involving seven people. Results: 1. Participants increased their interest in health and oral health by managing their hypertension, diabetes, and periodontal disease using community resources. Through this, healthy practices and improved awareness helped to prevent complications and manage periodontal diseases. 2. Community organizations actively cooperated, resulting in positive changes in oral health practices (increased registration of patients in education centers for hypertension and diabetes, and increased number of patients visiting the local dental clinic). In the future, it was positive to participate in the program continuously. Conclusions: The most important step is 'Entry into community', which has led to active participation and cooperation of community organizations and participants. Therefore, community organizations and strategy development should be discussed, and the role of community leaders should be emphasized to build cooperative relationships. In addition, participation in and collaboration with health-based projects should be achieved through a search of various community organizations.
