Effect of a mouthwash containing cetylpyridinium chloride and zinc acetate / 대한구강보건학회지

Objectives@#This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. @*Methods@#A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. @*Results@#Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). @*Conclusions@#Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

The effect of quality of life and interpersonal relationship satisfaction on academic achievement in dental hygiene students / 대한구강보건학회지

Objectives@#This study was conducted to investigate the effect of quality of life and interpersonal relationship satisfaction on academic achievement among dental hygiene students. @*Methods@#A survey was conducted on 210 dental hygiene students from Chungcheong, Jeolla, and Gyeongsang. @*Results@#The factors affecting the academic achievement of dental hygiene students were interpersonal relationship satisfaction (β=0.489), quality of life (β=0.243), and grade_dum3 (<2.5/≥3.5; β=0.206). The most significant factor was interpersonal satisfaction, with an explanatory power of 37%. @*Conclusions@#As a result of the above, it was found that quality of life and interpersonal satisfaction were closely related to the academic achievement of dental hygiene students. Further research on ways to improve academic achievement is needed.

Oral health status depending on the type of national health insurance: the 7th Korea National Health and Nutrition Examination Survey (KNHANES Ⅶ) / 대한구강보건학회지

Objectives@#This study was conducted to analyze dental caries and periodontal diseases in Korean adults depending on types of national health insurance, using data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES Ⅶ). @*Methods@#From 2016 to 2018, the final analysis included a total of 12,601 adults over 19 years of age, who had undergone dental inspections for dental caries and periodontitis, and whose national health insurance was verified. @*Results@#Among all the subjects, the ratio of employees was highest (67.4%), followed by the self-employed (39.4%), and then medical care recipients (3.3%). The prevalence of dental caries and periodontitis was 93.0% and 30.5%, respectively, among all subjects. The former was highest for medical aid recipients (95.9%), followed by employees (93.1%), and was lowest for the self-employed (92.2%) (P<0.001). The latter was highest for medical aid recipients (40.7%), followed by the self-employed (35.9%), and was lowest for employees (27.7%) (P<0.001). The prevalence of dental caries in the self-employed group was significantly lower (0.52 times) than that of medical care recipients (95% CI: 0.28-0.94), while no significant difference was seen between the latter and employees. There were also no significant differences among them, depending on the types of national health insurance and periodontitis. @*Conclusions@#It is necessary to develop oral health promotion programs that are not biased toward specific types of health insurance subscriptions, and to establish a business plan for oral prevention of subscribers of medical benefits.

Preliminary study for the development of a visiting oral health care intervention program for the elderly based on community healthcare / 대한구강보건학회지

Objectives@#We evaluated the level of oral health status and oral health behavior in the elderly prior to their participation in a visiting oral health care intervention program as part of a community healthcare project in Cheonan city, South Korea. @*Methods@#The oral hygiene conditions, oral health behaviors, and oral senility of 64 elderly people subject to community care were measured during the period January 1 to February 15, 2020 using dental health surveys and questionnaire-based interviews conducted in line with World Health Organization standard criteria. @*Results@#The systematic disease retention rate of the elderly in this study was 90.6%, followed by hypertention (70.7%), and diabetes (51.7%). Scores were 1.69 out of 5 for subjective health evaluation, 1.8 out of 5 for subjective awareness of oral health, and the number of natural teeth was 14.9 per person (average mean for elderly people 18.38-19.34). During the day, 94.9% practiced brushing, after dinner 58.9%, and before bedtime 26.8%, which shows a diminished rate of practice. The percentage of participants dissatisfied with dental treatment was high at 67.2%, and the six measures of oral sensitivity, masticatory discomfort, pronunciation discomfort, and tongue pressure, presented less than average scores. @*Conclusions@#The level of oral health and oral health behavior of the elderly prior to the visiting oral health care community intervention program, was very poor. Therefore, the results of this study suggest that there is a need to develop a more systematic and thorough strategy to activate visiting community oral health care intervention programs.

Inhibitory effect of the probiotic bacteria, Weissella cibaria CMU on halitosis: a randomized placebo-controlled study / 대한구강보건학회지

Objectives@#Previous studies have suggested that the lactic acid bacterium, Weissella cibaria CMU has beneficial effects on halitosis, but its precise effects have not been evaluated in human subjects. We evaluated the efficacy and safety of W. cibaria CMU for reducing halitosis in adults (20-70 years old) whose exhibited volatile sulfur compound (VSC) concentrations exceeded 0.015 ng/mL and who scored ≥2 points in a halitosis sensory evaluation test. @*Methods@#A total of 60 participants were assigned to an experimental group (treated with W. cibaria CMU) and a control group (placebo). In total, 58 out of 60 participants (experimental group, 29; control group, 29) were ultimately included in gas chromatography (OralChroma) analyses of VSC concentrations and halitosis sensory evaluation tests. @*Results@#We found that the VSC concentration decreased by 0.030±0.062 ng/ml in the experimental group after 8 weeks (P=0.0138) and increased by 0.005±0.124 ng/ml in the control group (P=0.8198). However, the difference between groups was not statistically significant (P>0.05). In a sensory evaluation test, a significantly lower score was obtained for the experimental group than for the control group. @*Conclusions@#Overall, VSC concentrations and sensory evaluation scores were lower in the experimental group than in the control group, but only the latter was statistically significant. Thus, we conclude that W. cibaria CMU is involved in the reduction of halitosis.
