To educate the technique performing oral health care by oneself, four times individualized oral instruction was introduced to patients and control marks of plaque on sex, age, occupation, monthly average income, academic career were measured respectively. Through analysis of it's results and evaluation of oral health care grade on patients, this study arranged for basic data about individualized oral instruction to improve public oral health. 1. As individualized oral instruction was processed, control mark of dentalplaque improved greatly. 2. Control mark of dentalplaque on sex, female's control mark was higher than male's it. But, a gap of control mark was small. 3. Control mark of dentalplaque on age, control mark of patients in their 50s to 59s and 30s to 39s was higher than average of the whole. 4. Control mark of dentalplaque on occupation, control mark of inoccupation and professional was highly appeared. 5. Control mark of dentalplaque on monthly average income, control mark of patients whose monthly average income was below 2.5 million was highly appeared. 6. Control mark of dentalplaque on academic career, control mark of patients who graduated of university was highly appeared at first and second evaluation. On the other hand, control mark of patients who graduated of college or dropped out of university was highly appeared at third and fourth evaluation. According to the above statements, to effectively take care of oral health, our felt keenly the necessity of the individualized repeated instruction.

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.

Gingivitis is the most prevalent type of periodontal disease and the dental plaque is considered as a major contributory factor. As the poor oral hygiene is firmly related to the occurrence of periodontal disease, pediatric dentist should make every effort to promote the oral health and control the plaque effectively for the high risk patients, especially for those who are under orthodontic treatment. P.M.T.C.(Professional Mechanical Tooth Cleaning), introduced by Dr. P. Axelsson in 1969, is a very effective method of plaque removal and can be performed by specially trained personnel. Two pediatric orthodontic patients were treated by P.M.T.C. for the elimination of gingivitis and gingival swelling. Signi ficant improvements of gingival condition were achieved in both cases but additional preventive programs and home care along with professional office care seem to be necessary for the best result.

Objectives: Smoking is related to periodontal disease and periodontal therapy. So the aim of this study was to investigate the effects of professional tooth cleaning and plaque control instruction (PT & PCI) for smoking behavior. Methods: A total of 151 adults were investigated using the O'Leary Plaque Index (PI), $L\ddot{o}e$ & Silness gingival index (GI) and the number of sextants possessing periodontal pocket (SPP). And adults were given a through dental scaling and Watanabe method for dental plaque control. Follow up examination were conducted after 3 months and compared the pre and post- status. The collected data were analyzed with t-test, paired t-test and one-way analysis of variance. Results: Regardless of smoking behavior, improving effects were identified after PT & PCI on PI, GI and SPP in the whole population. However, the effects of GI improvement were significant in the smoking group alone; those of PI improvement were most significant in the non-smoking group; and those of SPP improvement were more significant in non-smoking and pre-smoking groups than in the smoking group. The shorter period of smoking and the smaller amount of smoking, the greater effects of PT & PCI by smoking-related characteristics. Conclusion: Smoking cessation instruction should necessarily be included in oral health education in that smoking is an important factor to consider in prevention of periodontal diseases and periodontal therapies.

To investigate the necessity of periodontal treatments, and the association of the health lifestyle with periodontal treatments, the data of 11,488 adults targeted in the 5th (2010, 2012) National Health and Nutrition Examination Survey were used in this study. Chi-squared test was conducted to compare the subjects' general features with the health lifestyle of the patients who needed periodontal treatments. Logistic regression analyses were conducted to confirm the variables that could affect the necessity of periodontal treatments. As a result of verifying the necessity of periodontal treatments according to the general features and health lifestyle, the necessity decreased with the higher income level and education level, and in the cases of nonsmokers, frequent toothbrushing, and using oral hygiene products. When the subjects who did not had oral examinations, their necessity for periodontal treatments significantly increased (p<0.01). The variables that affected the necessity of periodontal treatments included residence, gender, education level, obesity, and oral examinations (p<0.01). Therefore, health lifestyle was thought an important variable that had affected the oral health status. Professional dental hygienists must provide people with action programs of health lifestyle to promote the national oral health status.

Background: This study aimed to identify the present level and needs of clinical dental hygienists and to present the Borich needs assessment and the locus for focus model as integrated priorities. Methods: The participants of this study were dental hygienists working in dental clinics (hospitals). The final data of the 194 participants were analyzed using frequency analysis and a paired sample t-test. To analyze the need for clinical dental hygienists to perform work, the Borich priority determination formula was used. The x-y plane consisting of four quadrants was used to analyze the need using the locus for focus model, which helps to determine the priority while showing visual effects. Results: "Scaling" was the highest required level for clinical dental hygienists, and "panorama taking" was the highest present level. The priorities of educational needs were systematically and visually derived from dental hygienists who were currently working through the Borich needs assessment and the locus for focus model for each task performed in the clinical field. Through the priorities of these two models, a total of 13 items appeared in the common high-level area; "oral health care (disability)," "oral health care (systemic disease)," "applying a rubber dam," "professional mechanical tooth cleaning," "root planing," "taking vital signs," "medication counseling," "wire cutting," "removing cement after removing band/bracket," "delivering bracket," "preparing mini-screw implantation," "dental insurance claim," and "patient reception." Conclusion: Based on the results, the department of dental hygiene should maintain and improve the standardized clinical practice curriculum and clinical dental hygienists' practical skills and contribute to the realization of the legal scope of dental hygienists, reflecting the requirements of clinical fields.

Objectives: As medical history before surgery is often based on patient reporting, there is the possibility that patients intentionally hide underlying diseases or that dentists cannot recognize abnormal health states. Therefore, more professional and reliable treatment processes are needed under the Korean dental specialist system. The purpose of this study was to elucidate the necessity of a preoperative blood testing routine prior to office-based surgery under local anesthesia. Patients and Methods: Preoperative blood lab data for 5,022 patients from January 2018 to December 2019 were assembled. Study participants were those who underwent extraction or implant surgery under local anesthesia at Seoul National University Dental Hospital. Preoperative blood tests included complete blood count (CBC), blood chemistry, serum electrolyte, serology, and blood coagulation data. Values outside of the normal range were considered an "abnormality," and the percentage of abnormalities among the total number of patients was calculated. Patients were divided into two groups based on the presence of underlying disease. The rates of abnormalities in the blood tests were compared between groups. Chi-square tests were performed to compare data from the two groups, and P<0.05 was considered statistically significant. Results: The percentages of males and females in the study were 48.0% and 52.0%, respectively. Of all patients, 17.0% (Group B) reported known systemic disease, while 83.0% (Group A) reported no specific medical history. There were significant differences between Groups A and B in CBC, coagulation panel, electrolytes, and chemistry panel (P<0.05). In Group A, the results of blood tests that required a change in procedure were identified even though the proportion was very small. Conclusion: Preoperative blood tests for office-based surgery can detect underlying medical conditions that are difficult to identify from patient history alone and can prevent unexpected sequelae. In addition, such tests can result in a more professional treatment process and build patient confidence in the dentist.
