Dental chair unit (DCU) is the most essential equipment for the dental treatment in dentistry. DCU output water is used for various applications during dental treatment. DCU output water must be clean at the same level as drinking water since patients and dental staff are regularly exposed to water and aerosols generated from the DCU. Many studies demonstrated that DCU output water is frequently contaminated with microorganisms including opportunistic pathogen such as Legionella and Pseudomonas species. Thus, DCU output water may be a potential source of infection. In order to reduce microbial contamination levels in DCU output water, periodic management and continuous disinfection are necessary. Currently, there are a variety of disinfection methods for managing DCU output water and its efficacy is also diverse. We reviewed the level of microbial contamination, clinical implications of contaminated DCU output water and the various DCU disinfection methods.

One of the most critical causes in determining the clinical outcomes of dental prostheses is the validity of models. However, studies that evaluated validity of digital models are few. The objectives of this study were to evaluate validity of edentulous digital models for full denture fabrication. Twenty stone models (edentulous model) were manufactured and scanned by dental blue light emitting diode scanner. Twenty digital models were manufactured. Six linear distances (inter-canine distance, inter-molar distance, two dental arch lengths (right, left), two diagonal of dental arch lengths (right, left) were measured for validity evaluation. The measurements of distances of stone models were used by digital vernier caliper and digital models were used by computer program. The mean
deviations values of six distances were calculated. The means were compared by the Mann Whitney U test (
). All statistical analysis were performed using IBM SPSS Statistics ver. 20.0. Although digital models were smaller than stone models in six distances, there were no significant differences (p>0.05) and non exceeded the clinical acceptable range. The edentulous digital models for full denture fabrication can be considered clinically acceptable.

The purpose of this study was to investigate the performance of dental infection control. This survey was performed on 158 of the dental hygienist in certain areas. The research was performed using a self-reported questionnaire and interview method from June to July, 2014. The collected data was analyzed by PASW Statistics ver. 18.0. Guideline of infection management, infection controller, regular infection control training, Sterilization of the handpiece/per head resulted 57~74% for dental hospital. It was higher than 13~20% for dental clinics (p<0.05). Infection control guidelines and vaccination recognition of dental were more performed in dental hospital. Patient's hand hygiene performed, tooth brushing before treatment, cross infection educational experience was less than 20%, research cooperation of medical history was over 90% (p<0.05). Performing rate of the dental hospital workers were investigated higher in protective personal devices, infection control of treatment room. A correlation analysis about institutional support, infection control of dental hygienists, patients with infection control cooperation showed a positive correlation statistically significant. Infection control can be enhanced when the medical staff, the patient, the organization combined cognitive and practice. Dental hygienist is required to recognize and practice the infection control guidelines through continuing education.

This study investigated flexural properties of indirect Gum-shade composite resins for esthetic improvement. The material utilized in this study was Crea.lign, Twiny flow and Twiny paste (TP). Ten specimens were fabricated with a dimension of
according to the ISO 4049. After fabrications, specimens were stored in the distilled water for 24 hours at the temperature of
. Three-point bending test was performed in universal testing machine (Instron 3344; Instron, USA) at a crosshead speed of 1 mm/min until the failure occurred. TP exhibited a higher flexural strength (FS) and flexural modulus (FM) compared to the flowable materials. There were significant differences among the three materials in FS and FM. However, there was no significant difference in work of fracture (WOF) in all tested materials (p>0.05). In Weibull analysis, TP showed the greatest Weibull modulus which means a higher reliability of the materials. Also, Gum-shade composite resins revealed a strong correlation in all flexural properties. There was a positive correlation in FS-FM (
) and a negative correlation between FS-WOF and FM-WOF (
). Therefore, this confirmed that flexural property was important for mechanical behavior evaluation and useful information. To addition, this improved among mechanical properties correlation of materials as important factor.

Recent cross-sectional studies indicate that obesity is a risk factor for periodontal disease. This study was aimed to investigate whether the four-week weight control program including caloric restriction and exercise training could have an effect on periodontal health. Forty-one obese (body mass index [BMI]
) and five overweight (
) students participated in the weight control program. Anthropometric data and oral examination data were collected at the baseline and at the 27th day. BMI, waist hip ratio (WHR), and percent of body fat (PBF) of the subjects decreased significantly, but gingival index, sites with bleeding on probing (BOP), and sites with shallow pocket depth didn't show the significant changes in paired t-test. There was no difference in the outcomes according to smoking, drinking alcohol, and sex. Nevertheless, PBF and sites with BOP (r=0.777) and WHR and sites with shallow pocket depth (r=0.444) showed positive correlations. PBF accounted for 58.9% of the variance in sites of BOP in regression analysis. We suggested that obesity might relate with periodontal health, although it was not clear whether weight control could influence on periodontal health directly.

Recently, energy drink consumption is rising. The purpose of this study was to examine the effect of energy drink on enamel erosion by measuring pH and titratable acidity in energy drink on the market. pH and titrable acidity in drink were measured by selecting 3 kinds of energy drinks with high sales volume among energy drinks on the domestic market. To evaluate the erosion level of normal enamel, the erosion level was measured by using a surface micro-hardness after soaking it in drink for 1 minute, for 3 minutes, for 5 minutes, for 10 minutes, and for 30 minutes while using 10 pieces of bovine specimens per each group. All the energy drinks were containing citric acid. As for pH in drinks, pH of Burn intense was the lowest with
. Hotsix stood at
. Redbull stood at
. In pH 5.5, the titrable acidity of Burn intense was 3.59 ml. Redbull was 3.43 ml. Hotsix was 1.92 ml. All the energy drinks were reduced the surface micro-hardness according to a rise in time of immersion. Following the 30-minute treatment in drinks, the surface micro-hardness value was indicated to be the lowest in Redbull with
VHN. It was shown to be in order of Hotsix
and Burn intense
. Hotsix and Burn intense had no statistically significant difference (p>0.05). Accordingly, all the energy drinks, which were used in the experiment, caused the tooth enamel erosion. Among them, Redbull led to the largest enamel erosion. Thus, energy drink containing citric acid and low pH can cause the enamel erosion. However, it is thought to be necessarily progressed by considering factors of influencing etching a little more diversely by additionally analyzing intraoral factors, acid kinds, and even the content in calcium, phosphate and fluoride.

DOI : 10.17135/jdhs.2015.15.4.424
The aim of this study was to investigate whether peripheral or central administration of triptolide is involved in pain modulation in inflammatory orofacial pain. The inflammatory orofacial pain was induced by the injection of 5% formalin into right vibrissa pad of rats. The pain behavioral response was measured the number of grooming or scratching on the orofacial area for 9 successive 5 minutes intervals. Triptolide was administrated into the identified vibrissa pad (12.5, 25,
) or intracisternal space (0.01, 0.1,
) 10 min before formalin injection. The nociceptive responses were reduced in the 2nd phase (11~45 minutes), particularly 20, 30 minutes after fomalin injection following administration of triptolide into vibrissa pad (25,
). Intracisternal (
) administration of triptolide alleviated the formalin-induced pain behaviors in the 2nd phase, especially 25~40 minutes after formalin injection. Triptolide could be a promising analgesic agent in the treatment of inflammatory orofacial pain.

Journal of dental hygiene science, volume 15, issue 4, 2015, Pages 430~436
DOI : 10.17135/jdhs.2015.15.4.430
This study examined the correlation of educational experience with practical behavior in infection control. Subjects were 152 dental hygienists in Gwangju from September 15 to October 5, 2015. The ratio of dental hygienists educated on infection control was higher in those worked in dental care with 2~4 dentist for 2~5 years and lower in those worked in dental cared with 1 dentist for 2~5 years (p<0.05, p<0.001). The dental hygienists with or without educational experience in infection control exhibited the highest activity rate in hand wash and the lowest in face protection. Barrier in health belief, was lower with the need for education in infection control among the factors affecting on the activity in infection control. The activity was higher with susceptibility and cue to action (p<0.05). Based on the results, education program on infection control should be developed, and applied periodically and obligatorily for dentist and all staffs of dental care to remove susceptibility and barrier, and to enhance cue to action. This will result the effective control of infection by elevating the health belief.

Due to the attractive benefits with regard to bone health, digestion, and hydration, carbonated water consumption have rapidly grown over the past few years. However, the acidic drink has latent potential for enamel erosion. The most experimental studies about the enamel erosion have focused on the carbonated beverages with sugar and artificial sweeteners. Here, we determined the enamel erosion potential by commercially available carbonated waters with bovine teeth. The erosion was verified by pH value, calcium concentration, and scanning electron microscope. Then plaque accumulation by bacterial adhesion was determined on the enamel erosion surface to measure roughness. In the present study, we observed that the increased calcium content after being immersed in carbonated waters result from the overall enamel erosion. There were no significant differences between general carbonated waters and mineral waters for erosive capacity. Therefore, commercially available carbonated waters are potentially erosive. In addition, oral bacteria strongly adhered to the erosive enamel surfaces thereby facilitating the development of dental plaque. Thus, it is urgently necessary to provide food safety information on the carbonated water as acidic drink to prevent the enamel erosion.

The aim of this study was to identify an effective control method of metabolic syndrome (MS) and oral diseases by investigating relationship between of MS and periodontal disease, tooth loss of the adult men and woman. We analyzed and concluded as follows, using a nationwide representative sample, in 8,225 middle senior citizens based on raw data of the 5th National Nutrition Survey in 2010, 2012. The data were analyzed by descriptive statistics, chi-squared test, and logistic regression using SAS ver. 9.2 program. The results are as follows, for correlation of metabolic component to periodontal disease, it was found that in men, the periodontal disease odds ratio of the group with abnormal fasting blood glucose increased 1.27 fold (95% confidence interval [CI], 1.04~1.54), and in woman, the odds ratios of the group with abnormal high density lipoprotein cholesterol increased 1.45 fold (95% CI, 1.22~1.72) and the odds ratio of the group with abnormal obesity increased 1.44 fold (95% CI, 1.17~1.77). For correlation of MS to periodontal disease, it was found that the odds ratio of periodontal disease in the woman at-risk group increased 1.55 fold (95% CI, 1.19~2.01) and that of the group with MS increased 2.25 fold (95% CI, 1.68~3.02). For correlation of woman's metabolic component to missing teeth, it was found that the odds ratio of group with abnormal blood pressure increased 1.41 fold (95% CI, 1.10~1.82). For correlation of woman's MS to missing teeth, it was found that the odds ratio of missing teeth in the group with MS increased 1.48 fold (95% CI, 1.07~2.04). It is considered that a public health project comprising preventive and systematic disease management is necessary for controlling MS and oral disease. The findings of the study are expected to lay the foundation for the development of oral health promotion programs.

The purpose of this study was to examine the relationship between image of dental hygienists and clinical practice satisfaction of dental hygiene students. The subjects in the study were 706 female students who majored in dental hygiene at randomly selected colleges, which were located in Daejeon, Ulsan, and North Chungcheong province. Data were gathered using structured questionnaires from October 20, 2014 to April 13, 2015. The major findings of the study were as follows: The average of satisfaction with clinical practice was 3.32, The average of image of dental hygienists was 3.55. As for clinical practice satisfaction by general and practice characteristics, there were statistically significant difference according to degree of satisfaction for major, as for image of dental hygienists, there were statistically significant difference according to grade, degree of satisfaction for major, number of clinical experience, practice organization and admission motive. The relationship of image of dental hygienists and clinical practice satisfaction was analyzed, and clinical practice satisfaction had a significant positive effect on image of dental hygienists. As a result of analyzing which variables affected image of dental hygienists, it's found that image of dental hygienists were under the influence of number of clinical experience, practice organization and clinical practice satisfaction. Clinical practice satisfaction influenced image of dental hygienists. Therefore, dental hygiene students are given a chance to have positive image through well-structured clinical practice.

The purpose of this study was to investigate the effects of educational training and psychosocial characteristics such as self-efficacy and social support on job involvement in dental hygienists. A total of 418 dental hygienists who were working in S, I and G area were recruited in this study. A self-administered questionnaire was used to evaluate individual and job characteristics, educational training, self-efficacy and social support of the study subjects. Hierarchical regression analysis was performed to examine the relationship of individual and job characteristics, educational training, self-efficacy and social support to job involvement. All statistical analyses were performed using the IBM SPSS Statistics ver. 20.0 for Windows, and p<0.05 was considered significant. The results show that learning experiences of liberal arts or social sciences as a part of college curriculum (t=-2.406), self-efficacy (t=3.728) and social support at work (t=4.391) were significantly associated with job involvement in dental hygienists. Dental hygienists who were having experiences of liberal arts or social sciences as a part of college curriculum, showing higher levels of self-efficacy, and receiving adequate social support from supervisors or coworkers at work were more likely to feel job involvement. They explained 17.4% of total variance of job involvement. This result suggests that experiences of liberal arts or social sciences as a part of college curriculum, higher levels of self-efficacy, and adequate social support from supervisors or coworkers at work might play an important role in increasing job involvement of dental hygienists. It is strongly required to develop individual and organizational program or training to promote a positive attitude to their job as a key professionals in the field of dental health, and to increase job involvement of dental hygienists.

DOI : 10.17135/jdhs.2015.15.4.472
The purpose of this study is to examine musculoskeletal disorders and grasp the relationship between working environment factors and stress and musculoskeletal disorders in dental hygienists. The self-administered questionnaire survey was conducted with 483 dental hygienists working in Gwangju who were selected by convenience sampling. Frequency analysis, crosstab analysis, t-test, and multiple logistic regression analysis were made. Subjects' musculoskeletal disorders that complain of severe pains were 29.8%. The relationship between working environment factors and stress and musculoskeletal disorders were examined. As a result, work break frequency of working environment factors and stress were found to influence musculoskeletal disorders. For working environment factors, the odds ratio of musculoskeletal disorders of the two breaks group was 0.29 (95% confidence interval [CI], 0.11~0.73), compared with the no break group, indicating less musculoskeletal disorders. However, no significant difference was found in one break and more than three breaks groups. The odds ratio of musculoskeletal disorders of stress was 0.44 (95% CI, 0.27~0.70), indicating negative correlation. As break frequency was moderate (two breaks), musculoskeletal disorders became decreased. Stress showed negative correlation with musculoskeletal disorders.

The purpose of this study was to examine the association between oral health status and health related quality of life (HRQoL). The study used a nationally representative sample of Koreans (2013 Korea National Health and Nutrition Examination Survey) aged 19~64 years (n=3,252). Dependent variable was HRQoL, which was assessed with each component of EuroQol-5 dimension (EQ5D). Independent variable was oral health status (oral pain, chewing problem, speaking problem, and perceived oral health). After adjustment for confounders (socio-demographic factors, oral health behaviors, health behaviors, and physical conditions), the risk of having poor HRQoL was greater in adults with poor oral health status. The odds ratio (OR) of having pain/discomfort were 1.50 (95% confidence interval [CI], 1.22~1.86) for respondents with oral pain, 1.72 (95% CI, 1.33~ 2.22) for respondents with chewing problem, 1.79 (95% CI, 1.22~2.62) for respondents with speaking problem, and 1.36 (95% CI, 1.09~1.70) for respondents with poor perceived oral health. The OR of having anxiety/depression were 1.74 (95% CI, 1.28~2.38) when having a chewing problem, 1.72 (95% CI, 1.12~2.64) when having a speaking problem, and 1.54 (95% CI, 1.14~2.08) when rating his/her oral health poor. Among Korean adults, two of the EQ5D components were associated with oral health status. Future study is needed to examine the detailed causal relations between oral health status and HRQoL longitudinally.

A recent report showed that nuclear factor of activated T cell (NFATc) 1 is a member of the NFAT family and is strictly implicated osteoblast differentiation and bone formation. Furthermore, the precise expression and function of NFATc1 in periodontal tissue remains unclear. Therefore, the purpose of this study was to investigate the function of NFATc1 in osteoblastic differentiation, and the underlying mechanism regulating periodontal regeneration in human periodontal ligament cells (hPDLCs). NFATc1 messenger RNA (mRNA) and protein levels were accessed by reverse transcription-polymerase chain reaction (RT-PCR) and western blot assay, respectively. Cell proliferation determined using MTT assay. Differentiation was evaluated by alkaline phosphatase activity and formation of calcium nodule with alizarin red S staining. The mRNA expression of osteoblastic differentiation related genes were examined by RT-PCR. Marked upregulation of NFATc1 mRNA and protein was observed in cells grown in osteogenic medium (OS). NFATc1 transactivation was detected in hPDLCs that had been incubated in OS for 14 days. Treatment with
cyclosporine A (CsA), a known calcineurin inhibitor, reduced the proliferation of hPDLCs, while
CsA had no effect. Inhibition of the calcineurin/NFATc1 pathway by CsA, attenuated OS-induced osteoblastic differentiation in hPDLCs. In summary, this study demonstrates for the first time that NFATc1 plays a key role in osteoblastic differentiation of hPDLCs and activation of NFATc1 could provide a novel mechanism for periodontal bone regeneration.

Journal of dental hygiene science, volume 15, issue 4, 2015, Pages 503~508
DOI : 10.17135/jdhs.2015.15.4.503
The purpose of this study was to examine factors related to the oral health by stress in college women. This survey was conducted between June 16, 2014 and July 18, 2014 to investigate the correlation between stress and oral health Data were obtained from 393 women students of 5 colleges in Gwangju and Jeollanam-do. The oral health of college students is related with the stress which has a correlation between oral condition satisfaction(-) and inconvenient(+) of mastication and pronunciation (p<0.01). Also, factors affecting stress are discomfort during mastication and oral state satisfaction and discomfort during mastication. The discomfort during mastication showed the highest stress while the higher status of oral satisfaction showed lower stress (p<0.05). Therefore, college women stress is related with oral health. Colleges should consider developing a program which can appropriately manage and regulate stress to relieve their stress.

Journal of dental hygiene science, volume 15, issue 4, 2015, Pages 509~517
DOI : 10.17135/jdhs.2015.15.4.509
This study attempted to identify the entrance exam stress levels in high school students and analyze the relationship this entrance exam stress and perceived oral health status. Self-administered survey was conducted in total 304 students attending in academic high schools in Bucheon. For analysis, SPSS was used to perform t-test and one-way ANOVA. As a result of the study, the entrance exam stress level of academic high school students was 2.71. The level of sub-factors were that tension for exam/poor result was highest by 3.08 and the next were future uncertainty (2.81), parents pressure (2.56), and insufficient free time (2.52). The group with high entrance exam stress showed significantly high perceived degrees of temporomandibular disorder, oral mucosal disease and xerostama. Among sub-factors of stress, the group with high tension for exam/poor result stress had significantly high perceived degrees of dental caries, teporomandibular disorder, oral mucosal disease and xerostama. Because perception on oral health issues increased with high entrance exam stress in high school students, it is necessary to seek some ways to decrease oral health problems even though entrance exam stress is intensified. To do so, it is inferred that it will be very important to promote oral health education to develop ability of high school students to practice correct oral management method.
