Comparative effects of aqueous single-phase and oil-water two-phase mouthrinses containing bamboo salt, magnolia bark and Centella asiatica extracts on reducing gingivitis: a randomized clinical trial / 대한구강보건학회지

OBJECTIVES: The aim of this study was to assess the antiplaque and antigingivitis effectiveness of aqueous single-phase and oil-water two-phase mouthrinses, containing bamboo salt, magnolia bark, and Centella asiatica extracts, in Korean adults. METHODS: In this double-blinded clinical trial, a total of thirty-four participants aged over 19 years were randomly allocated to three experimental groups: 1) control group; 2) aqueous single-phase mouthrinse (ASM) group, and; 3) oil-water two-phase mouthrinse (OTM) group. The experimental mouthrinses all contained sodium fluoride, and the ASM and OTM contained additional ingredients of bamboo salt, magnolia bark, and Centella asiatica extracts. For the OTM, 50% essential oil was added to create an oil-water two-phase mouthrinse. A two-week randomized crossover design with a two-week washout period was applied. Following a complete dental prophylaxis, participants were instructed to use the prescribed mouthrinse twice daily for two weeks as an adjunct to their usual mechanical oral hygiene procedures. Pre- and post-experiment clinical examinations were performed to measure the plaque index (PI) and bleeding on probing (BOP) for the full mouth. Paired t-test was applied to compare the intergroup differences for all clinical variables. RESULTS: Compared to the control group, ASM showed a significantly reduced BOP (P<0.05). However, there was no statistically significant difference in the effects of the three mouthrinses on reducing the PI. CONCLUSIONS: The results of this study indicate that the use of an aqueous, single-phase mouthrinse containing bamboo salt, magnolia bark and Centella asiatica extracts could help alleviate gingivitis.

Effects of Oral Health Education for Occupational Health Nurses / 치위생과학회지

The purpose of this study was to evaluate effects of oral health education for occupational health nurses. The subjects were 300 occupational health nurses which participated in continuing education of Korean Association of Occupational Health Nurses. Oral health education contents consisted of basic knowledge about oral health, prevention of periodontal disease, oral health care for workers, and oral health program for workers. In order to evaluate the effects of oral health education, we performed questionnaire surveys before and after the education regarding their perceived oral health status and concern for oral health, knowledge about prevention of periodontal disease, attitude about oral health promotion, and needs for implementation of oral health promotion program. The data were analyzed by paired t-test to compare the change of knowledge and attitude according to the education. Linear regression analysis was carried out to assess the factors related to the improvement of their knowledge and attitude. The findings indicated that oral health knowledge and attitude of occupational health nurses were significantly improved by oral health education. A factor of the improvement of knowledge and attitude was concern for oral health. And they would like to be provided primarily oral health education for occupational health nurses. Finally, this study suggested that oral health education for occupational health nurses had significantly effects on improving oral health knowledge and attitude.

Focus Group Interview on Opinion about the Design and Management of Toothbrushing Facilities / 치위생과학회지

This study collected opinions about the design and management of toothbrushing facilities from schoolteachers and the people in charge of public centers, through a focus group interview (FGI), for the development of guidelines. Four moderators conducted eight FGIs of 32 subjects in charge of toothbrushing facilities across all the regions. The qualitative data was analyzed by constant comparative analysis. The findings indicated that more students utilized the facility and brushed their teeth after the installation of toothbrushing facilities. To enhance students' accessibility and safety, guidelines for design and management guidelinesfor toothbrushing facilities need to be developed; the location, sink height and depth, drain size, etc. should be comprehensively considered in the development of the guidelines. This study can help to improve students' satisfaction by enhancing the accessibility, safety, and functionality of toothbrushing facilities, and by providing fundamental data for toothbrushing facilities' development. Finally, this study can maximize the effects of management of toothbrushing facilities management on the improvement of students' oral health and behaviors.

Effectiveness of a baking soda dentifrice on gingivitis and tooth surface / 대한구강보건학회지

OBJECTIVES: To evaluate the effectiveness of sodium bicarbonate dentifrices in reducing gingivitis and tooth abrasiveness and improving tooth gloss, as compared to a conventional fluoride/silica-containing dentifrice. METHODS: In this double-blinded, randomized clinical study with a paralleled design, 73 healthy adult volunteers (age, 18-39 years), with more than 20 teeth were selected and randomly allocated to the following groups: a control group, a 35% baking soda group, and a 65% baking soda group. Professional plaque controls were provided to all subjects and the same control dentifrice was used for 14 days. At baseline, all subjects received an assigned dentifrice and were instructed to brush three times daily. The tooth gloss and gingival bleeding index were measured at baseline, 45, and 90 days. For measuring surface roughness, toothbrushes were replaced with electronic tooth-brushing machines, and the bovine specimen was brushed via 10,000 horizontal shuttle movements. The surface roughness was measured by a confocal laser scanning microscope (CLSM; Carl Zeiss, LSM-5 Pascal, Germany) Each variable was analyzed by the paired t-test, and change in each variable among groups was analyzed by analysis of variance (ANOVA). Reliability of the gloss was analyzed by an intra-class correlation coefficient. RESULTS: Compared to the controls, the 65% sodium bicarbonate dentifrice group showed significant improvement with regard to the tooth gloss for 90 days as well as a significant inhibitory effect on gingivitis; the 35% sodium bicarbonate dentifrice group, however, showed no inhibitory effect on gingivitis. The relative roughness of the tooth surface in the dentifrices of both the sodium bicarbonate dentifrice groups was significantly low. Further, there was no significant difference with the distilled water group. CONCLUSIONS: The sodium bicarbonate dentifrice has an inhibitory effect on gingivitis. Further, this dentifrice showed low abrasiveness and a glossing effect on teeth.

Expert's opinions on the National Oral Health Examination evaluation system / 대한구강보건학회지

OBJECTIVES: The Delphi study was performed in Korea to develop a consensus opinion for the quality improvement in National oral health examination, and to obtain a basic data on how to improve the evaluation system of the National health examination. METHODS: Consensus was developed through two rounds of assessment in September and October, 2011. Seven professors and six dentists, recommended by Korean Dental Associations, were chosen as the Delphi experts. The Delphi questionnaire collected data in the following categories; management of facilities, preparation before oral screening, notice, certification of human resource, preservation of oral screening sheets, charge for oral screening, notification of agreement with using oral screening data, and the notification of oral screening results. To develop new criteria, the additional delphi questionnaire collected data in the following categories; human resource for dental screening, relevancy of instruments and facilities, a dental screening process. Respondents were asked to indicate their level of agreement with the questionnaire statements on a scale from 0 to 9 (0 indicating total disagreement and 9 indicating total agreement). The mean, coefficient of variation, median and agreement level were calculated. Agreement level was calculated by the proportion of respondents who chose more than 7. Consensus was considered to be defined when the agreement level was more than 45% in each section. RESULTS: Consensus was achieved in every criterion except for management of facilities, charge for oral screening and notification of agreement with using oral screening data. In new criteria, consensus was achieved in every criterion except for human resource for dental screening. CONCLUSIONS: Experts for the National Oral Health Examination in Korea achieved a consensus on certain aspects of the evaluation system of the National Oral Health Examination. It is needed to consider an improvement of the evaluation criteria on the National Oral Health Examination program.
