The purpose of this study was to examine the impact of the oral health behavior and self-rated oral health of workers on their happiness indexes in an attempt to provide information on oral health planning geared toward industrial workers. The subjects in this study were 294 workers in North Gyeongsang Province. As a result of analyzing the relationship between their health behavior and happiness indexes, the workers who got regular health checkups had higher happiness indexes for both single items(p=0.002) and entire five items(0.012), and those who had their teeth cleaned over the past year had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.003). As for a toothbrushing frequency, the respondents who brushed their teeth more frequently had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.023), and those who had ever received oral health education had higher happiness indexes for both single items(p=0.041) and entire five items. The workers who kept their toothbrushes at work had higher happiness indexes for both single items(p=0.001) and entire five items, and the respondents who could afford to visit a dental clinic immediately in case of having a toothache had higher happiness indexes for both single items(p<0.001) and entire five items(p<0.001). The findings of the study suggest that the preparation of systematic oral health programs is required to boost the happiness indexes of industrial workers.

The purpose of this study was to evaluate the abrasion-resistance of root surface after NaF iontophoresis, Nd:YAG laser irradiation and combined treatment 50 anterior teeth with flat interproximal root surface that had been extracted due to periodontal destruction were selected. All teeth were treated by the same procedure as conventional periodontal root treatment, such as scaling and root planing, root conditioning with tetracycline HCI(lOOmg/ml, 5min). The pre-treatment weight of each tooth was measured by a dial scale(SHIMADEU Co, LIBROR EB-220HU, capacity 220.000 g, Japan). All teeth were divided into 5 groups as follows: Nd:YAG laser irradiation(group 1, 1 W, 100 mJ, 10Hz, fiberoptic-root surface distance=5mm, $10\;sec.{\times}6times$, EL.EN.EN060, Italy): NaF iontophoresis(group 2, $150{\mu}A$, 4 min}: Nd:YAG laser irradiation following NaF iontophoresis(group 3): NaF iontophoresis following Nd:YAG laser irradiation(group 4): No treatment(control group). Electric toothbrushing (Oral-B, Brown Co, Germany) was conducted during 1 hour($lO\;min.{\times}6\;times$). Subsequently post-treatment weight was remeasured by the same method as pre-treatment weight measurement. The difference of abrasion rate among all groups was statistically analyzed by ANOVA(SAS program). Following results were obtained: 1. The abrasion rate was significantly lower in Nd:YAG laser irradiation group than NaF iontophoresis group(p < 0.001). 2. The abrasion rate was significantly lower in combined groups of Nd:YAG laser irradiation and NaF iontophoresis than either Nd:YAG laser irradiation group or NaF iontophoresis group(p < 0.001). 3. There was no significant difference in abrasion rate according to application order in the combined groups(p > 0.05). 4. The abrasion rate was significantly lower in all experimental groups than control group(p < 0.001). The results suggest that combined treatment of Nd:YAG laser irradiation and NaF iontophoresis on exposed root surface after periodontal therapy can enhance the abrasion-resistance of root surface and may inhibit the root caries development.

With the change of medical environment, people are taking interest not just in treatment but in the prevention of oral diseases. As people's interest in oral diseases increases, the number of dental institutions is increasing continuously and this is heightening the necessity and importance of professional dental hygienists equipped with expert knowledge of oral health. Thus the present study purposed to survey and analyze the current state and weight of works carried out by dental hygienists, and to propose dental hygienists' works desirable in the medical environment changing its focus from treatment to prevention. The results of this study are as follows; 1. In the results of dividing dental hygienists' works into oral examination and preliminary examination, preventive works, assistance to dental treatment, oral health education, hospital administration and management, and surveying the performance rate of these works, the work of the highest performance rate in preliminary examination was collection of patients' systemic history (87.6%). It was also scaling (96.9%) in preventive dental treatment, preparation for treatment (96.5%) in assistance to dental treatment, education on the toothbrushing method (92.3%) in oral health education, and tool disinfection and management (72.2%) in hospital administration and management. 2. When the performance rate was surveyed according to age, institution, and work experience, the performance rate by work area was highest in dental hygienists aged between 27~28, those working at a dental clinic, and those with 4~6 years' work experience. 3. The weight of dental hygienists' works was high in order of assistance to dental treatment (59.1%), observation of oral health condition and preliminary examination (12.4%), oral health education (12.4%), hospital administration and management (10.4%), and preventive dental treatment (5.8%), but in the results of surveying perception on the importance of works, the importance was high in order of oral health education (34.7%), preventive dental treatment (29.0%), observation of oral health condition and preliminary examination (19.3%), assistance to dental treatment (11.2%), and hospital administration and management (5.8%), showing that the weight of works carried out current was different from perception on the weight of works regarded as important. 4. To the question on parts to be developed in response to the change of medical environment, the most frequent answers were the establishment of their roles as preventive dental practitioners (75.7%), and the establishment of their roles as oral health educators (74.9%). This was consistent with the works that dental hygienists gave the highest weight to, and suggested that dental hygienists regarded preventive dental treatment as most important. Development of abilities to give counsel to patients was 55.2%, acquisition of theoretical knowledge of dental treatment 42.1%, improvement in quality as a hospital manager 28.2%, and acquisition of skills to assist dental treatment 23.2%. These show that, even with regard to the development of future oriented dental hygienists' capacities, assistance to dental treatment was perceived less important as it was with regard to the importance of work.

Objectives : The purpose of this study was to examine factors affecting the effective demand of workers for dental treatment in a bid to provide some information on the improvement of oral health. Methods : The subjects in this study were 255 workers who were engaged in the pharmaceutical industry. A self-administered survey was conducted, and the collected data were analyzed by a spss(statistical package for the social science) win 12.0 program to find out their demographic characteristics, oral health awareness, oral health behavior and factors for the choice of a dental institution. Results : 1. Concerning the level of oral health awareness, 47.0 percent were at a low level(0 to three scores), and 35.2 percent were at an intermediate level(four to six scores). 2. As to oral health behavior involving a daily mean toothbrushing frequency, they brushed their teeth 2.65 times per day on the average. The most widely utilized oral hygiene supply was mouth rinse. Regarding oral health status, 53.7 percent weren't in good dental health, and just 23.0 percent got a dental checkup on a regular basis. 45.8 percent of those who didn't get a dental checkup cited time constraints as the reason. 26.0 percent received oral health education, and 91.4 percent were aware of the necessity of a corporate incremental dental care system. 3. Marital status, age and the reliability of dental institutions made differences to their choice of a dental institution. 4. As for the relationship between oral health awareness and the factors for the choice of a dental institution, oral health awareness had a statistically significant positive correlation to the reliability of dental institutions. Conclusions : The above-mentioned findings suggest that oral health education enables workers to have a correct knowledge on oral health, to change their own oral health behavior and to make the right choice of a dental institution in consideration of their oral characteristics. They should be urged to get a regular dental checkup not to develop chronic oral diseases so that they couldn't have to receive first-aid dental treatment. To promote the oral health of workers, oral health care personnels available should be utilized, and the incremental dental care system should be more vitalized to cut down on their effective demand for dental treatment.
