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.

Determining the Relationship among Organizational Commitment, Occupational Stress, and Interpersonal Relations according to Adult Attachment Styles of Clinical Dental Hygienists / 치위생과학회지

BACKGROUND: This study aimed to identify the types of adult attachment and determine the relationship between adult attachment and job factors in dental hygienists. Ultimately, it was necessary to identify the need for a secure attachment to improve the quality of clinical dental hygienist's services. METHODS: Data of 454 clinical dental hygienists working in dental hospitals or clinics were collected. The research tools consisted of items related to the general and work characteristics of dental hygienists (9 items), adult attachment styles (36 items), organizational commitments (12 items), occupational stress (15 items), and interpersonal relations (18 items). Cronbach's α of each tool was ≥0.7. RESULTS: Most of the participants had fearful attachment styles, followed by dismissing-avoidance, security, and preoccupation. Security was the highest level of organizational commitment according to the adult attachment style, although the differences of the levels were insignificant. For occupational stress, preoccupation was the highest, followed by fearful, security, and dismissing-avoidance, and the differences were significant (p<0.001). For interpersonal relations, security was the highest, followed by preoccupation, dismissing-avoidance, and fearful in order, and the differences were significant (p<0.001). CONCLUSION: Job stress and interpersonal relation ability according to the adult attachment style of clinical dental hygienists had significant results. Thus, the development of attachment improvement programs by personal style, development of differentiated clinical education and its application, and improvements in the adult attachment styles of clinical dental hygienists would be required rather than simply presenting the needs to collectively improvement the working environment.

The Effect of Children's Beverages on Degradation of Dental Resin-Based Pit and Fissure Sealant / 치위생과학회지

The consumption of beverages among children is rising. The purpose of this study was to examine the effect of kid's drink on dental resin-based pit and fissure sealant. Pororo, I-kicker, Sunkist kids were included in the experimental groups, and Samdasu was included in the control group. A conventional dental sealant material (Clinpro™Sealant®) was selected for this study. Resin specimens (8 mm in diameter and 1 mm in thickness) were prepared according to manufacturers' instructions and the initial roughness (Ra) was then measured. The pH of all the four groups was measured using a pH meter. The specimens were individually immersed in 5 ml of the experimental solutions and stored at 37℃ for 72 hours. Following this, the surface roughness of the resin specimens was measured by Surftest. The concentration of residual monomer released was determined by high performance liquid chromatography (HPLC). The surface morphology of the resin specimen was evaluated before and after storage by scanning electron microscopy (SEM). Data were statistically analyzed using Kruskal-Wallis and Duncan's test. The results showed that all the children's beverages examined in this study contained citric acid. The pH of I-kicker was the lowest (3.03±0.01), followed by that of Sunkist kids (3.26±0.02) and Pororo (3.47±0.02). We observed an increase in the surface roughness of resin specimens after 72 h of immersion in all the beverages tested (p < 0.05). There was matrix degradation after immersion, visualized on SEM image, in all the beverage groups. Bisphenol-A-glycidyl methacrylate was not detected after 72 hours, but triethylene glycol dimethacrylate levels were increased in all the beverages tested during the 72 hours by HPLC. These results suggest that intake of beverages containing acid can cause degradation of the resin-based pit and fissure sealants in children.
