Oral examination ensures early detection and treatment of oral diseases and improvement of quality of health-related life. This is imperative as it reduces individuals' dental medical expenses and social costs caused by diseases. However, as the low oral examination acceptance rate continues to be a problem, this study was conducted to identify the factors that influence the oral examination of an economically active population. In this study, 4,836 economically active individuals between the ages of 20 and 65 years were studied using data from the 7th National Health and Nutrition Survey in 2018. Logistic regression analysis was performed to determine the factors influencing demographic and sociological characteristics on oral examination after adjusting for complaints of mastication and speech discomfort. As a result of confirming the factors influencing the oral examination, increase in age tended to be inversely proportional to the oral examination. Income level, type of job, and job position were identified as factors that influenced oral examinations. Compared to the group with a high socioeconomic status, which is represented by a group with a high income level or a stable job type or job position, the group with low economic status was found to have a negative effect on oral examination. Oral management of vulnerable groups, who might not be considered while devising oral health management policies, should be promoted through the development and provision of oral health management policies that consider employment status and environment.
Objectives: To investigate the perceived quality of classes, academic emotions, and learning achievement levels associated with the non-face-to-face classes of health science students, and to analyze the factors related to class satisfaction. Methods: Using a questionnaire, 238 health science students were surveyed regarding the quality of classes, academic emotions, and learning achievement levels. Factors related to calss satisfaction were analyzed using stepwise multiple regression. Results: Lecture types that the students were most satisfied with were 'video lectures using PPT' and 'recorded lectures provided by LMS', while 'real-time video lectures' were scored the lowest (p=0.005). Factors affecting non-face-to-face class satisfaction were perceived achievement (β=0.425, p<0.001), learning content (β=0.265, p<0.001), learning emotion (β=0.171, p<0.001), and learning environment (β=0.137, p=0.012). The adjusted explanatory power for this model was 63.9%. Conclusions: To increase the satisfaction of health science students with non-face-to-face classes, it is necessary to prepare an institutional foundation and to develop an educational program that can increase perceived achievement.
This study was the study verifying dental technicians' motivation and job satisfaction in Seoul through the positive method as well as its purposes were to investigated the effect of dental technicians manpower supply/demand prospect on motivation, job satisfaction and the effect of other job satisfaction factors on dental technicians motivation and job satisfaction. For then, general characteristics of study objects were classified by sex, married/unmarried, age, career, salary, highest level of education, working place, position and job as well as job satisfaction factors were classified with future supply/demand prospect, future prospect, working hours, working environment and salary. We conducted a frequency analysis, crossing analysis and multi-linear regression analysis about the effect of the classified articles on motivation and job satisfaction. Also, for verifying the relationship of motivation and job satisfaction, we conducted correlation analysis and its result is as followed. First, it showed that the job related with making orthodontic appliance influenced on motivation, among the age, career and job of the general characteristics, and other jobs between working place and job influenced on job satisfaction. Second, the dark future prospect was showed to influence on motivation and job satisfaction highly so we could grasp that negative opinions are included in that. And low-paying was showed to highly influence on job satisfaction s fall so we could grasp the subjective low-salary standard at the present. But we expected that the manpower supply/demand prospect would influence on motivation and job satisfaction but there was little influence. Third, the correlation between motivation and job satisfaction was showed to be somewhat high, motivation had the standard which is above average and job satisfaction had the standard which is below the average. So with a little improving of job satisfaction, it s possible that motivation can be very high. Therefore, in rapidly changing generation, we think that the dental technicians are actively coping with the reality of low-paying and high-working. But it's implying that anxiety for uncertain future was reflected. Furthermore, because institutional strategies for dental technicians' efficient management are insufficient in relation with policies so it's necessary the policy consideration for solve the job-unsatisfying factors actively.

To investigate the correlation between the perceived symptom of musculoskeletal diseases and psychosocial factors in dental professionals in Chungcheong province, a self-administered survey was conducted on 206 dental professionals in Chungcheong province from March 9th, 2009 to March 28th, 2009. SPSS WIN 12.0 software was used to analyze the data and the following results were obtained. 1. As for the perceived symptom degree of musculoskeletal diseases based on measured body parts, the frequency of 'high' was the highest in all the parts of the body. 2. As for gender, females showed higher interest in musculoskeletal diseases than males (p=.000). As for age, subjects ranged 26~30 years showed the highest interest in musculoskeletal diseases, which was statistically significant (p=.000). 3. Work satisfaction showed a positive correlation with the perceived symptom of musculoskeletal diseases in lumbar group and lower extremity group. Work stress showed a weak negative correlation with the perceived symptom of musculoskeletal diseases in lumbar group and lower extremity group. Coworker satisfaction showed a positive correlations with the perceived symptom in upper extremity group and lower extremity group. Hospital satisfaction showed a positive correlations with the perceived symptom in upper extremity group, lumbar group and lower extremity group. Working environment satisfaction showed a positive correlations with the perceived symptom in neck group, shoulder group, upper extremity group and lower extremity group. This study showed a correlation between psychosocial factors and the perceived symptom of musculoskeletal diseases based on body parts. Therefore, psychosocial factors should be considered when the prevention and management program of musculoskeletal diseases are developed.
This study was conducted to provide basic data on the relationship between the happiness and job satisfaction of dental hygienists. The research subjects were 264 dental hygienists in Busan and Gyeongsangnam-do. The study was conducted using structured questionnaires and the collected data were analyzed using IBM SPSS software, ver. 20.0. The happiness index, which was based on general characteristics, showed the greatest significant differences in life satisfaction (p<0.05) among adults over 36 years of job experience, negative emotions (p<0.01) among adults under 25 years of job experience, and negative emotions (p<0.05) among adults with 4~10 years of job experience. The factors that improved the job satisfaction of dental hygienists were life satisfaction, prime duty at the work place, and a positive effect. On the contrary, negative emotions lowered the job satisfaction. The happiness of the dental hygienist is an important factor not only for the improvement of the hygienist's personal quality of life, but also the patient's health. It is necessary for dental hygienists to maintain good relationships with coworkers during in the workplace, as well as employers, to have an administrative system that offers proper compensation, improvement of the work environment, and opportunities to improve professionalism at the workplace.
Dental caries is induced by organic acids produced by oral bacteria. In order to prevent dental caries, therefore, it is essential to maintain neutral pH in the oral cavity. Urea plays a major role in oral pH homeostasis. Urea is hydrolyzed by bacterial ureases to ammonia, causing a pH elevation. Streptococcus salivarius has been shown to be a major contribution to oral ureolysis. Synthesis of urease by S. salivarius appears to be constituitive, but can be greatly enhanced by low pH. It is, therefore, conceivable that ureolytic activity of S. salivarius from a carious lesion is greater than that of the bacterium from a healthy tooth. In the present study, urease activity of S. salivarius isolates from dental plaque of carious lesions was compared with that of the isolates from plaques of the teeth and the dorsum of the tongue; 45 S. salivarius strains were isofated from carious lesions(>C2) of 21 individuals with dental caries and 30 strains from 10 individuals without dental caries. The results were as follows: 1. All the 21 individuals with dental caries harbored ureolytic S. salivarius whereas 3 of 13 individuals without dental caries harbored non-ureolytic strains of S. salivarius. 2. All the 45 S. saliuarius isolates from carious lesions showed urease activity. In contrast, of 30 isolates from individuals without dental caries, 17 isolates(56.7%) did not demonstrate urease activity, or if any, very little(<5${\mu}mol$/min/mg). 3. Urease activity of the isolates from carious lesions was greater than that of the isolates from individuals without dental caries : the urease activity ranged from 42 to $381{\mu}mol$/min/mg and from 0 to $208{\mu}mol$/min/mg, respectively. 4. At acid pH(5.5), the isolates which showed intermediate urease activity at pH 7.0 demonstrated even higher activity whereas the isolate with no or lower urease activity did not show any significant difference in their activity. However, the isolates with the greatest urease activity from both individuals with and without dental caries, exhibited a rather much lower urease activity at pH 5.5. The overall results suggest that isolates may have their own urease activity but the isolates exposed to chronic acidic environment of the carious lesion might elevate urease activity of S. salivarius, which in turn, might influence on survival of S. salivarius itself and other bacteria, establishing a new oral bacterial ecosystem.
In conclusion, so far, the researcher took into account the correlativity between Patient Hygiene Performance Index and Simplified Oral Hygiene Index in order to diagnose the oral environment of smoker group and nonsmoker group. From the above results, there showed some difference between each indexes, but hadn't significant difference statistically, which means that hadn't significant difference between two groups on account of selecting the groups(smoker group, nonsmoker group) having a similar ability with regard to Patient Hygiene Performance. With regard to the effect of smoking period, smoking quantity, smoking quantity per year on Patient Hygiene Performance and Simplified Oral Hygiene Index, the researcher knew that smoking has a marked effect on patient's oral environment management.

Dental implants using titanium have greatly advanced through the improvement of designs and surface treatments. Nonetheless, the anatomical limits and physiological changes of the patient are still regarded as obstacles in increasing the success rate of implants further, even with the enhancement of implant products. So there have been many efforts to overcome these limits. The intrinsic potential for bone regeneration can be stimulated through adjuvant treatments with the continuous improvement of implant properties, and this can play an important role in achieving optimum osseointegration toward peripheral bone tissue and securing ultimate long-term implant stability in standard surgical procedures. For this purpose, various chemical, biological, or biophysical measures were developed such as bone grafts, materials, pharmacological agents, growth factors, and bone formation proteins. The biophysical stimulation of bone union includes non-invasive and safe methods. In the beginning, it was developed as a method to enhance the healing of fractures, but later evolved into Pulsed Electromagnetic Field, Low-Intensity Pulsed Ultrasound, and Low-Level Laser Therapy. Their beneficial effects were confirmed in many studies. This study sought to examine bone-implant union and its latest trend as well as the biophysical stimulation method to enhance the union. In particular, this study suggested the enhancement of the function of cells and tissues under a disadvantageous bone metabolism environment through such adjunctive stimulation. This study is expected to serve as a treatment guideline for implant-bone union under unfavorable circumstances caused by systemic diseases hampering bone metabolism or the host environment.
