The purpose of this study was to investigate the stress and life satisfaction of dental hygienists working in dental clinics and clinics in Gwangju and Jeonnam from September 15 to November 30,Respectively. 1. The stresses of the subjects were significantly different according to age (F=2.780, p<0.05), final academic ability (F=4.397, p<0.05) and average salary (F=4.159, p<0.01) 2. The life satisfaction of the study subjects showed significant difference according to age (F=4.075, p<0.01), final academic ability (F=9.295, p<0.001) and average salary (F=5.487, p<0.001).

The purpose of this study was to provide basic data for the continuous oral health management of university students by analyzing the influence of oral health beliefs on scaling behavior of 333 college students in Gwangju and Chonnam area. As follows. 1. The importance of oral health beliefs was found to be higher in women over 20 years old (p=0.001), in 4th grade (p=0.009), in women (p<0.001) (p=0,022), indicating a statistically significant difference. The benefit was highest in children aged 20 years or older (p=0.005) and fourth grade (p=0.006). 2. Sensitivity, severity, and disability of oral health beliefs were high (p<0.001) when the perceived subjective health status was bad (p=0.001) Respectively. (P=0.006), oral health education experience (p=0.006), scaling experience (p=0.006), and subjective oral health status (p=0.041) Respectively. 3. Subjective oral health perception was positively correlated with severity, severity, and disability (p<0.001). 4. As the perceived sensitivity of oral care products increased by one unit, the probability of using oral care products decreased 0.511 times (p<0.05), and the importance and importance of the oral care aids increased 1.689 times (p=0.034) And 1.621 times (p=0.047), respectively. 5. As a factor affecting the scaling experience, the probability of scaling increased 1.637 times (p=0.047). In conclusion, it is necessary to improve the awareness of the prevention goal scaling which is implemented from July, 2013 for college students, and to make the oral health care properly by reflecting the results of oral health beliefs.

The purpose of this study is to understand relations between dental hygienists’ subjective work environment and subjective pain symptoms in different regions and improve the environment of their treatment room and help them reduce pain in different areas. The subjects of this study are 250 dental hygienists. Data were collected from March until April, 2015 through a survey with self-administered questionnaire sheets, and the results of analysis are as written below. 1. Concerning the subjects’ general characteristics, 98.4% were females. About their age, 64.0% were ‘from 20 to 29’, and about years of service, ‘many years of service (over 6 years)’ formed 4.08%. About types of hospitals they worked for, ‘dental clinic’ formed the most as 7.08%, and about the department they worked for, ‘operative and prosthetic dentistry’ formed the biggest part as 30.4%. 2. About the subjects’ subjective health conditions, ‘I am healthy’ formed the biggest part as 39.6%, and about the areas of subjective pain, pain was felt the most in their neck as 19.4%, shoulders as 19.0%, waist as 17.5%, and legs as 16.3% in order. About ways to prevent or cure pain, ‘resting’ formed 33.2% and ‘no experience of being treated’ formed 21.6%, and about the degree of resting while working, ‘I rest sometimes’ formed 62.0%. 3. Regarding their subjective work environment, ‘physical environment’ received a low point as 2.89±0.51. About detailed items, they regarded their physical environment to be not very favorable giving low points to ‘There is little noise.’, ‘The treatment room is quite well equipped with ventilation facilities (windows or ventilators).’, and ‘An extra chair is equipped to each of the chair on the treatment room.’ in order. 4. Concerning their subjective pain symptoms in different regions, muscle symptoms received the lowest point as 2.40±0.78. About detailed items, ‘My shoulders are painful or uncomfortable.’ gained 2.20±0.92 points, and ‘My lower limbs (legs, knees, or feet) are painful or uncomfortable.’ received 2.37±1.00 points, and ‘My lumbar region (waist or back) is painful or uncomfortable.’ gained a low point as 2.38±0.97. 5. Regarding their subjective work environment and subjective pain symptoms in relation to general characteristics, there was no significant difference by years of service. About types of hospitals they worked for, dental clinics gained low points in ‘physical environment’, ‘the job system and environment’, and ‘muscle symptoms’, which indicated significant difference (p<0.05). About the degree of resting while working, ‘I hardly rest.’ was found to be low in ‘job environment and duties’, ‘skin symptoms’, ‘muscle symptoms’, and ‘psychological symptoms’, which indicated significant difference (p<0.05).

Periodontal diseases are one of major dental diseases that commonly happen in oral cavity. They tend to start with initial inflammation, and if they are not managed appropriately, they would cause the loss of teeth, which is a chronic disease. Patients should recognize their oral health for themselves. This study is to find out the relationship between the subjective recognition and objective assessment results. Therefore, the purpose of this study is to find out whether the subjective recognition is related to oral environment or not. This study was conducted in from June 2015 to October. Oral health assessment and survey were carried out to the adult subjects of this study who were over 19 years and visited dental clinics located in Seoul and Gyeonggi-do Province. The factors influencing oral environment was analyzed according to the subjects’ characteristics of social demography. In TPI(p<0.001), S-PHP(p<0.001), PMA(p<0.044), CPI(p<0.000), male’ figure is higher than female’ one. In a smoker group, the figure of both male and female is noticeably high in TPI(p<0.001), S-PHP(p<0.004), PMA(p<0.009), CPI(p<0.002). The factors influencing oral hygiene was analyzed according to the subjective recognition about periodontal diseases. For people who have suffered from periodontal diseases, their figures of S-PHP(p<0.010), PMA(p<0.011), CPI(p<0.024) are high, and for people who have suffered from tooth mobility, their figures are high in S-PHP(p<0.008), PMA(p<0.002), CPI(p<0.002). The figures of TPI(p<0.007), PMA(p<0.010), CPI(p<0.002) are noticeably high for the group who do not use dental floss. The factors influencing oral environment was analyzed according to the subjective recognition about oral hygiene care. The unhealthier oral health is, the higher the figure is in S-PHP(p<0.001), PMA(p<0.028), CPI(p<0.004). The less often brushing teeth is performed, the higher the figures in TPI(<0.001), S-PHP(p<0.008), PMA(p<0.033), CPI(p<0.004) are. The poorer ability to manage oral hygiene care the subjects have, their figures are noticeably high in TPI(p<0.001), S-PHP(p<0.001), PMA(p<0.002), CPI(p<0.000). There are 3 relevant factors between subjective recognition about periodontal diseases and oral environment: chewing difficulty(p<0.001) in S-PHP, alveolar bone resoption(p<.0001) in PMA, and tooth mobility(p<0.011) in CPI. As the results are indicated above, adults’ subjective recognition about periodontal diseases is not related to oral environment. Preventive programs effective for oral health care should be developed so that adult-centered dental health education programs can be activated.

The purpose of this study was to recognize the risk of poor oral hygiene from second-hand smoking as well as first-hand smoking. This study analyzed the oral hygiene by measuring PHP index of 211 male technical high school students according to smoking conditions. PHP index was calcualted by QLF-D and tooth surface disclosing method. 1. PHP index of first-hand smokers was significantly higher than that of non first-hand smokers(p<0.01). 2. PHP index of second-hand smokers was significantly higher than that of non second-hand smokers(p<0.05). 3. PHP index was significantly different according to smoking conditions. The index of first-hand smokers who had exposed to second-hand smoking was the highest while the index of non smokers was the lowest(p<0.01). Given the findings of the study, smoking conditions could affect the oral hygiene of youth. Especially even involuntary smoking influences the oral hygiene of youth.

There are many researches after 1960 which show water irrigation device can be used safely to intra oral tissues, remove dental plaque effectively, and reduce gingival bleeding and gingivitis. Water irrigation device can be used for every general dental patient, but also much more effective device for the patients with gingivitis, dental implant, dental crown, bridge, fixed orthodontic appliances, and mostly for those who feel difficulties in using dental floss or interdental brushes. It is necessary for the oral hygienic professionals to recommend and educate about this device to help those patients. There are still few researches about the safety and effectiveness of water irrigation device to the dental implant, we hope to get more research data soon.

By reviewing related literatures from 1989, we found some relationship between malocclusion and dental caries. Although there are some differences in terms of the degree of relationship and the interpretation of results among literatures, we can say if there is any malocclusion such as anterior malalignment, it can lead more accumulation of plaque in that maloccluded area, result in more dental caries experiences. As insisted in some researches, the actual and direct effect factor on dental caries is oral hygienic care and plaque control. This means proper oral hygienic care and education by oral hygienic professionals are necessary to the patients with malocclusion to overcome their difficulties in oral hygienic care and plaque control.

This study compared averages of opening credits and opening hours according to the educational system as to the national examination subjects such as conservative dentistry, dental prosthetics, periodontal studies, oral and maxillofacial surgery, dental materials, pediatric dentistry, orthodontics belonging to clinical dental hygiene fields on the target of 75 colleges (91.5%) carrying the curriculum in the homepages among 82 colleges with a dental hygiene department. As for the curriculum of clinical subjects opened as integrated subjects, by dividing dental clinics into I to VI, compared averages of credits and hours for integrated subjects according to the educational system, and investigated the current state of name usages of integrated subjects. Following are the results of this study. Firstly, the distribution of credits for clinical subjects with three year based schools was between 2.09 and 2.30, and the distribution of credits with four year based schools was between 2.00 and 2.55, from which periodontal studies was shown to be the highest credit among every educational system. Secondly, with a look at the current state of operation for integrated curriculum of clinical subjects, 13 schools (26.5%) with three year based system and 21 schools (80.8%) with four year based system ran the operation of integrated curriculum. Thirdly, in the curriculum of integrated subjects, dental clinics 1 in three year based system was shown to be the highest with 2.73 credits and 2.90 hours, and dental clinics 1 in four year based system was also shown to be the highest with 2.67 credits and 2.86 hours. Fourthly, in terms of the titles of integrated subjects, there were 17 schools (50%) that used the subject name of clinical dentistry, 10 schools (29.4%) using dental clinics, and 3 schools (8.8%) using clinical dental hygiene, etc., and there were diverse titles for integrated subjects that were in use. Accordingly, it is necessary to derive a consented curriculum plan through constant researches for clinical subjects of integrated curriculum more systemic and consistent in order to reinforce and improve professionalism of dental hygienists.
