Objectives. The purpose of this study was to assess and compare the amount of toothpaste used by varying opening diameter and squeezing methods in children aged 3∼5 to prevent the excessive use of fluoride toothpaste. Methods. The amount of toothpaste per brushing was measured from a sample of 176 infants aged 3∼5 in 6 nurseries located in Jecheon City, Chungbuk Province, Korea. We tested two squeezing methods, pea-size and transverse technique, and two openings, 0.6 cm and 0.9 cm. We compared the amount of toothpaste used relative to opening diameter and squeezing methods through paired t-test using SPSS 14.0. Results. For 0.6 cm or 0.9 cm diameters with the pea-size method, the amount of toothpaste used was 0.22 g or 0.51 g, respectively (p<0.001). For 0.6 cm or 0.9 cm diameters and the transverse technique, the amount of toothpaste used was 0.20 g or 0.46 g, respectively (p<0.001). In case of 0.9 cm diameter, the amount of toothpaste showed significant difference according to squeezing methods (0.9 cm: p=0.045, 0.6 cm: p=0.121). Conclusions. Smaller openings restrict the amount of toothpaste used and would reduce unnecessary fluoride ingestion.

Objectives: The purpose of this study was to evaluate abrasion of Icon® infiltrated, sound bovine enamel by using confocal laser scanning microscopy (CLSM) after toothbrush abrasion tests. Methods: Sound bovine enamel specimens whose Vickers Hardness Number ranged from 280 to 320 were prepared. To measure abrasion, specimens were allocated to groups on the basis of tooth brushing stroke frequencies. Tooth brushing stroke frequencies were categorized into 5 groups: 1,800, 5,400, 10,800, 21,600 and 43,200 strokes. Both infiltration depth of Icon® and the abrasion depth were measured by CLSM. Results: Mean infiltration depth of Icon® for sound bovine enamel was 98.6 μm. There was no statistically significant difference in enamel abrasion depth between groups with 5,400 strokes and 10,800 strokes, but the abrasion depth increased with further increase in tooth brushing stroke frequencies ( P<0.001). The mean abrasion depth of resin infiltrated bovine enamel after 43,200 tooth brushing strokes was 17.45 μm. Conclusions: The magnitude of abrasion after 43,200 tooth brushing strokes, which corresponds to brushing 3 times a day for 4 years, was less than 20 μm. This result suggests that abrasion by tooth brushing would not be a clinical problem for resin infiltrated enamel.

Objectives: In this study, we aimed to analyze draft regulations for home dental care services by evaluating focus group interview data and applying the five supply-side dimensions of the Levesque accessibility framework from the perspective of the provider. We also sought to identify key issues and suggest improvements to enhance the appropriateness of the draft and inform future implementation. Methods: Interview data were analyzed based on the five supply-side dimensions of the Levesque framework: approachability, acceptability, availability and accommodation, affordability, and appropriateness. Key themes were extracted and comparatively analyzed among the three participant groups: academics, clinicians, and stakeholders. The findings were interpreted in alignment with the operational definitions of the framework, and representative quotations were included to emphasize the core messages. Results: The analysis indicated that public sector leadership is essential for effective home dental care services. There was a particular emphasis on enhancing service outcomes through community engagement and addressing care gaps. However, participants identified the need for improved public-private collaboration, clarification of roles for public officials, workforce expansion, financial burden reduction, and the establishment of clear regulatory guidelines. Conclusions: This study highlights the necessity of establishing legal and institutional frameworks for home dental care services, including enforcement decrees, health insurance coverage, and financial support. To reduce regional disparities, policy measures should support the expansion of professional personnel, under the responsibility of local governments. These findings provide foundational evidence for the development and sustainable implementation of home dental care services.

The purpose of this study was to examine the validity of the content of an educational curriculum by understanding the opinions of experts in the development of weekly educational content for dental communication or communication-related subjects. It was composed of educational content on how to communicate with patients by cultivating a professional attitude through basic contents and a self-understanding of communication. Three experts were asked to evaluate the feasibility of educational contents and their appropriateness in order to evaluate the criteria for certification as a dental hygienist. The validity of the weekly educational contents and the period of education were awarded 4 points out of a maximum of 5 points; overall, the curriculum was evaluated to be valid and to be acceptable for use as criteria for certification evaluation. On the other hand, it was confirmed that not only should the contents be made appropriate for the grade level, but it should be complemented so that theoretical and practical learning can be achieved in a gradual and interrelated manner rather than as a one-time curriculum. Therefore, the result of this study can be considered for use as background data for curriculum development, and for standardization of the communication course in the dental hygiene department.

최용금 ( Yong-keum Choi ),신보미 ( Bo-mi Shin ),손정희 ( Jung-hui Son ),박덕영 ( Deok-young Park ) 한국치위생과학회 2016 치위생과학회지 Vol.16 No.2
The purpose of this study was to develop a dental communication course in dental hygiene schools that included theory, practice, and skill for effective dental communication. Thirty-six senior dental hygiene students in a dental hygiene school took a dental communication course and responded to a questionnaire. The instrument used in the study was a modified form of Kim’s communication skill self-assessment sheet. The self-assessment questionnaire about communication competencies was administered before and after the class, and the difference between scores at each time point was analyzed using the Wilcoxon signed rank sum test. Among seven elements of dental communication competencies, the competency of “information gathering” was significantly improved (p=0.008). Students’ scores on perception of the importance (p=0.019) and necessity (0.016) of a communication course significantly increased after the course. Competencies in communication are essential requirement for dental hygienists. This study showed the possibility of communication skill training. An objective evaluation tool regarding students’ communication competencies should be developed. Further studies with larger samples size are needed to develop a standardized comprehensive communication course in dental hygiene schools.

The purpose of this study was to analyze the effects of perceived stress on dietary habits and oral health behaviors in Korean adolescents. Data were from the Korea Youth Risk Behavior Web-based Survey (KYRBS) in 2011. A total of 74,186 adolescents were surveyed using the self-administered questionnaire. Logistic regression analyses were performed to elucidate the effects of perceived stress on dietary habits and oral health behaviors. Statistical analyses were conducted, and p<0.05 were considered significant. We found that adolescents with higher stress were more likely to increase the risk of adverse dietary habits (low consumption of fruits, vegetables and milk, high consumption of carbonated soft drinks, fast food and cookie) compared to those with lower stress. Regarding the relationship between perceived stress and oral health behaviors, adolescents with higher stress were less likely to practice oral health behaviors such as brushing teeth after snack consumption and brushing teeth before sleep compared to those with lower stress. This result indicates that adolescents` perceived stress might play a significant role in the negative dietary habits and oral health behavior.

To find out the effect of commercially available energy drinks on tooth enamel erosion, analyzed pH, buffering capacity, and the content of some of the inorganic components selecting 4 energy drinks that has high affinity of the products currently being sold. In addition, by observing the degree of erosion before and after immersion in energy drink by surface microhardness and scanning electron microscope (SEM) the results were as follows: Acidity of energy drink ?Burn Intense? was the lowest as 2.78±0.01 highest on distilled water as 6.475±0.01. ?Burn Intense? buffering capacity was 3.48±0.155 at pH 5.5, 1.88±0.15 at pH 7.0 which is the highest, and ?Hot6? was 1.71±0.37, 1.23±0.35 on each of it showing the lowest points. Ca content on energy drink was the highest at ?Volt Energy? as (77.21±2.70 mg/kg), the lowest at ?Hot6? as (0.98±0.05 mg/kg). P content was the highest on ?Hot6?(1.34±0.05 mg/kg) and detected at ?Red Bull?. Enamel surface hardness variation of the energy drinks before and after immersion showed rapid decrease at ?Red Bull? (66.65±35.60), and ?Volt Energy? (61.96±31.42), ?Burn Intense? (58.53±24.84), ?Hot6? (53.99±60.26) was in order. Distilled water, the control group, showed significant difference with the experimental group (p<0.05). But there was no significant difference between energy drinks. At SEM observation and analysis, ?Burn Intense? was the most severe demineralization, ?Volt Energy?, ?Hot6?, ?Red Bull?, distilled water was in order. In the above results, taken together there were no statistically differences between energy drinks but significant difference in comparison with distilled water. In addition, at SEM observation and analysis all energy drink caused dental erosion, especially ?Burn Intense?, has the lowest acidity, was serious. Thus, it is believed to provide a variety of oral health education and information about energy drinks that can affect the erosion of the teeth so public have the right to be recognized and reasonable dental care.
