Purpose: This study sought to identify factors associated with dental hygienists' decisions to leave one dental office and commence practice in another. In addition to, the reasons dental hygienists stay in the profession were investigated. Demographic descriptors, including education level, marital status and age, and employment setting were also examined. Methods: Currently practicing dental hygienists in Korea were surveyed from March to May 2003. Data were collected through a questionnaire. The survey collected information concerning the 461 respondents' personal characteristics and reasons associated with changing positions and staying. Data were analyzed using frequency distributions, independent t-tests and chi-square analyses. All statistical analyses were conducted using the Statistical Package for Social Scientists(SPSS v.10, Chicago, Illinois). Results: The primary reasons for taking up another employment were found to be better offer, inadequate salary and personal conflict with dentist. Secondary reasons stated for changing their job revealed additional factors including inadequate salary, better offer, and lack of benefits. The primary influence in deciding to remaining in the practice of dental hygiene was self-development. Family responsibility, safe environment and professional collaboration were also important factors in deciding to remain in workforce. Conclusion: The position changes of dental hygienists are primarily influenced by better offer. Inadequate salary and conflict with dentist were also important factors in deciding to change employment positions. The findings suggest that dental hygienists who remain in the workforce are positively influenced mainly by self-development. Employers of dental hygienists should be aware of these factors in employing process. If more hygienists could remain longer in their positions, the manpower situation would be affected positively.

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 ${\alpha}$ of each tool was ${\geq}0.7$. 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 purpose of this study was to provide information on the development of an oral-health promotion program geared toward office workers. The subjects in this study were 240 employees at the headquarters of S construction company. After a survey was conducted in July and August 2008, the answer sheets from 208 respondents were gathered, and 191 answer sheets were analyzed except 17 unanalyzable ones. The findings of the study were as follows: 1. In regard to subjective oral health status, the largest number of the participants that accounted for 37.2% found their mouth to be neither healthy nor unhealthy. The greatest number of them that represented 58.1% had never visited a dentist's office to receive preventive treatment. 2. Regarding relationship between toothbrushing education experience and toothbrushing frequency, the most common toothbrushing frequency was three times a day( 46.5%) among the company employees who had ever received that education. In the event of the office workers without that experience, the most prevalent frequency was three times(63.6%). The toothbrushing frequency was statistically significantly different according to the toothbrushing education experience(p<0.05). As to the relationship of toothbrushing education experience to tooth- brushing method, the largest number(48.2%) of those who had ever received that education brushed their upper and lower teeth along with the gums by rotating the toothbrush downward from the top and upward from the bottom respectively. In the event of the office workers without that experience, 49.4 percent brushed their teeth and gums by rotating the toothbrush up and down. Thus, whether they had ever received education about toothbrushing made a statistically significant difference to their toothbrushing method(p<0.05). 3. As a result of evaluating their oral health belief by utilizing a five-point scale, they got a mean of 2.95. In each area of oral health belief, they got the best marks in benefit(3.66), salience(3.42), barrier(2.84), susceptility(2.58) and seriousness(2.23). Given the above-mentioned finding of the study, two sorts of oral health beliefs, which are benefit and salience, should be stressed in the development of oral health education programs that cater to company employees. And sustained research efforts should be channeled into finding out the relationship between oral health and actual oral health care.

The purpose of this study was to evaluate color change and enamel surface changes using the plasma arc light source during tooth bleaching treatments. Twenty-four extracted bovine incisors were selected and embedded in the resin blocks. All the specimens were highly polished and discolored with commercial $COCK^{(R)}$. High concentration carbamide peroxide with and without plasma arc were used for bleaching. Specimens were bleached for 1 hour per week during 3 weeks. Color and enamel surface changes were determined with colorimeter (TC-8600A), microhardness tester(MXT-a7), scanning electron microscope(S-4200). All the collected data analyzed with paired t-test, t-test and one-way ANOVA. After the bleaching, both groups showed the color changes(${\Delta}E^*$). Microhardness of two group decreased after tooth bleaching. The SEM evaluation of enamel surface of both group showed a similar morphology of decalcification after tooth bleaching. Office bleaching using the plasma arc application with 35% carbamide peroxide can increase the color change. Office bleaching using the high concentration of carbamide peroxide and plasma arc also detract the outer surface of enamel. It is recommended that careful procedures are needed during office bleaching with high concentration of carbamide peroxide and light source.

This study investigates the potential of cone-beam computed tomography (CBCT)-generated cephalograms as a replacement for conventional lateral cephalograms (LCs) in children and adolescents. This retrospective study included 60 individuals, equally divided into permanent and mixed dentition groups. Both groups underwent conventional LCs and CBCT scans on the same day. LCs were then derived from CBCT scans. The same examiner performed digital measurements twice, with a week's interval, identifying landmarks and obtaining 7 angular and 5 linear measurements. In the permanent dentition group, significant differences were observed between the two imaging modalities for 6 angular and 2 linear measurements. In the mixed dentition group, significant differences were observed for 3 angular and 2 linear measurements. However, none of these differences exceeded the clinically acceptable limit of 2.0° or 2.0 mm. No significant differences in any measurement were found between the two groups (p < 0.05). CBCT-generated LCs demonstrated comparable results with good reliability in both dentition groups, suggesting their potential as suitable alternatives for children and adolescents who require CBCT for clinical purposes.

The purpose of this study was to classify the courses of the dental-hygiene curricula into several categories by field, to incorporate the subjects in the same category into an integrated course, and to suggest how to ensure the successful phase-in application of integrative education according to Ronald M. Harden's 11-stage integrative ladder model. The findings of the study were as follows: 1. When the existing curricula were analyzed, it's found that many credits were provided to the courses in the area of basic dentistry that offered both theory and practice. In particular, the subjects tested by the national examination were offered by every college. In the field of public oral health, the largest number of credits was allocated to theory of oral prophylaxis and practice courses. In clinical area, clinical practice, in the area of dental office management, dental insurance course was given the largest credit. There were 31 to 61 major subjects in the colleges, which indicated that the major subjects were segmented in detail. 2. It seemed necessary to incorporate the subjects in the field of basic dentistry into oral biology, and theory of oral prophylaxis/practice, preventive dentistry/practice, preclinical stage, emergency treatment and introduction to dental hygiene should be integrated in to clinical dental hygiene. The courses in clinical area should be combined into clinical dentistry, and in the field of medical management, dental insurance, hospital management and medical relation law should be incorporated into management of dental clinic. 3. In the 11-stage integrative ladder, the subjects in the same field could perfectly be incorporated as the stages advanced. Each of the subjects was less emphasized, and communication and joint plans among teachers who were respectively in charge of the courses were increasingly considered important. Specifically, there should be a consensus among the teachers in regard to the outline of teaching programs, order of education. objects and objectives of programs and what and how to evaluate.

Purpose: This study was designed to investigate the present conditions of illumination techniques in dental clinics in order to contribute improvement of operating environment. This study also aimed exploring qualitative and quantitative luminous intensity required for color temperature in dental clinic illumination, which was a critical part of esthetic dentistry. Materials and methods: A total of forty-eight local dental clinics were selected for sampling a) luminous intensity, and b) color temperature. The author measured the luminous intensity and the color temperature with lux meter and color meter respectively between 12pm and 2pm. The dental unit chair placed in the general operation positions were kept the distance 60 cm then all dental units were measured three times and averaged. The author measured the luminous intensity and color temperature with both common dental operating light and then without operating light in different office environments. The study was conducted under three conditions: 1 artificial illumination in clear day light 2. artificial illumination in cloudy day light, and 3. artificial illumination alone. Results : The results obtained were as follows. 1. The average luminous intensity in dental clinic lighting was 425 lux which was not sufficient to produce the optimal shade of the patient's teeth. Furthermore, the average luminous intensity even in full operating lighting was 9532 lux which fell short of the required level of 10,000 lux. 2. The average color temperature of all dental clinics surveyed was 5169 K which met the optimal range. However, only 33.3% fell in the correct region between 5,000-5,500 K as 25% were over 5,500 K and 41.6% were below 5,000 K. As a result, 66.7% were under insufficient color temperature conditions. 3. The dental unit chair placed next to a window, hence exposure to natural lighting, had significantly higher luminous intensity and color temperature compared to the dental unit chair which didn't have a window or natural lighting. 4. The data analysis revealed that only 6.3% of the dental clinic were met the standard of the average luminous intensity and color temperature.

Objectives: This study was conducted by clinical dentistry hygienists to develop knowledge measurement tools and evaluate knowledge necessary to cope with emergencies related to systemic diseases occurring in dentistry. Methods: Basic questions were developed on the six most frequently occurring diseases in the dental office: diabetes, syncope, respiratory disease, coronary artery disease, cerebrovascular disease, and epilepsy. Fifty-eight preliminary questions were composed in a survey format through expert validation. The survey was then conducted on 290 dental hygienists to verify the composition validity and reliability. Factor and reliability analyses were performed using the SPSS 23.0 program, and the correct answer rate for each question was calculated. Results: 49 items of a total of 13 factors were adopted as the final items for signs, symptoms, prevention and treatment of five diseases. The question with the highest percentage of correct answers for each question was "Slowly set up the unit chair when raising the patient"(97.9%) during the prevention of unconsciousness and question with the lowest correct answer rate was "soft substances such as cloth should be put in the mouth to prevent trauma while the seizure persists" (16.6%). Conclusions: A total of 49 questions have been developed as tools to measure the knowledge of dental hygienists' first aid related to systemic diseases and it is expected that related curriculum can be operated or evaluated by using them.

This study explored the status of free time activities among the dental technicians who are working at Seoul, Gyonggido, and Gangwondo. On the basis of this research, we aim to present needs and applicable solutions to improve the working conditions and enhance the quality of life through more effective time management in free time activities that lead to their self development and far more enriched life. 500 subjects were randomly chosen and the questionary sheets were provided. Among them, 305 sheets were returned to be analysed through SPSS Win 10.0 software and the results are as follows; First, mean in the satisfaction of leisure activities was 3.44(SD=.73). Mean in sub categories was as follows; psychological factor(M=3.65, SD=.71), social factor(M=3.54, SD=.75), rest factors(M=3.52, SD=.63), physical factor(M=3.43, SD=.88), other factors(M=3.40, SD=.66), circumstantial factor(M=3.33, SD=.63), educational factor(M=3.24, SD=.73). Second, the most relevant sub categories in the satisfaction of leisure activities were social, educational, physical, and other circumstantial factors by sequence. Factors that affect leisure activities satisfaction were career and status of health, which shows statistical significance(p<.001). That is to say, contention of this study is that the general characteristics are closely related with and affect the types and the level of satisfaction in leisure activities of the subjects. Considering these results, the dental businesses and the associations of dental technicians should recognize the needs to improve the time management through more efficient cooperations between dentists and back office dental team, systemized working time, and introduction of incentive system among others. On the basis of this appreciation, the dental business should provide more time and various opportunities with the dental technicians. Dental technicians also need to reconsider their appreciations of leisure activities, that is, leisure activities are not just spending time doing something but they refresh them and enable them to be more active and faithful to home and work.
