In most persons with disabilities had poor oral hygiene because of less attention and ability to perform a dental care. So the increased prevalence and severity of dental disease were common oral state. Although most persons with disabilities need a adequate dental treatment, it is often very difficult to treat because of noncooperativity and involuntary muscle movements. Dental treatments under sedation and general anesthesia were make to provide a high-quality dental service because of decreased anxiety and fear associated dental treatment in persons with disabilities. The dental professionals must be able to select and apply the proper sedation methods in agreement with the characteristics of the disabilities, general conditions, sedation experience and capacity of dentist, type and time of dental treatment, equipments of dental clinic, consent of patient's protector. The proshodontic treatment procedures, such as abutment preparation, dental impression taking process, try-in process of prosthesis and adjustment of occlusion, are difficult even for patients without disabilities. Those procedures are more difficult to patients with disability because it's too hard to control breathing and muscle. In this report, we performed prosthetic dentistry procedures to three patients with disabilities under dental sedation and general anesthesia.

This study was aimed to identify the diffusion of systemic disease-related knowledge among dental hygienists. Two hundreds and eleven dental hygienists were selected for the study. Data was collected between August 31, 2015 and September 20, 2015 by handing out questionnaires. Returned questionnaires were analyzed by descriptive statistics, t-test, and ANOVA. Dental hygienists showed overall mean of 0.64 on the systemic disease related knowledge. Age, education level, career, and educational experience showed significant influence on the systemic disease knowledge (p<0.01). Dental hygienists revealed overall mean of 0.61 (full mark=1) on the usefulness recognition of systemic disease related knowledge. Age (p<0.001), education level (p<0.01), career (p<0.001), and educational experience (p<0.01) showed significant effects on the usefulness recognition of systemic disease knowledge. Degree of how dental hygienists apply the systemic disease-related knowledge to the service was mean 0.86 (full mark=2). Age (p<0.01), education level (p<0.01), career (p<0.01), and educational experience (p<0.001) had significant impacts on how dental hygienists apply the systemic disease related knowledge to the service. The diffusion of systemic disease knowledge among dental hygienists was 2.17, which represented 'persuade'. These results indicated that a study is needed to understand the diffusion of systemic disease knowledge among dental hygienists and to identify obstacles in the process. Moreover, an education program should be developed to offer practical training on the systemic disease-related knowledge. Further studies should evaluate the effectiveness of the program.

The purpose of this study was to examine the awareness of dental hygienists on ethical dilemma. The subjects in this study were 356 dental hygienists who worked in dental clinics. After a survey was conducted, the collected data were analyzed with a SPSSWIN 14.0 program. The findings of the study were as follows: 1. In relation to awareness of ethical principles, 64.9 percent knew the fact that there were ethical principles to abide by, though they weren't aware of the principles in detail. When they were in ethical dilemma, most of them consulted with their colleagues(84.0%). 2. As to the necessity of ethical education, 86.8 percent felt the need for that. Concerning intention of receiving ethical education, however, as many as 41.6 percent didn't yet have any particular intention about that, and 50.0 percent intended to receive that education. 3. As for influential factors for ethical decision making, hospital policies and decision-making process were most influential(3.50), and fear for a possible loss of job exerted the smallest influence on that(2.49). 4. Regarding the cause of ethical dilemma, they fell into an ethical dilemma the most due to their own professional duties(2.56), followed by patients(2.33) and cooperators(2.28).

The purpose of this study was to obtain data necessary for guiding students in the future by grasping which rate of error is made how much depending on a shooting technique in the filming of periapical radiograph. 14,402 films, which were instructed targeting students for the Department of Dental Hygiene at D Health College and S Health College, were analyzed. The following results were obtained by conducting questionnaire survey targeting 263 students who completed the shooting practice lesson of bisecting angle technique and paralleling technique. 1. In case of having shot with bisecting angle technique, the ratio of error was the highest in both maxillary and mandibular first molar. 2. In case of having shot with paralleling technique, the ratio of error was the highest in the maxillary bicuspid and the mandibular first molar. 3. As for ratio of error in light of a shooting technique, both bisecting angle technique and paralleling technique were indicated to be the highest in inaccuracy of film position. The bisecting angle technique was indicated to have the higher ratio of error compared to the paralleling technique. 4. As for ratio of error in light of the processing technique, both bisecting angle technique and paralleling technique were indicated to be the highest in dark image and light image. The bisecting angle technique was indicated to have the higher ratio of error compared to the paralleling technique. 5. Students were indicated to feel it to be most difficult for grasping the processing level in the film-developing process. As the above results, to reduce ratio of error given the periapical radiography, a method of reducing ratio of error given the periapical radiography is considered to be what correctly understands the morphological and anatomical structure inside the mouth and what acquires the shooting technique by filming several times with having enough time.

Streptococcus mutans is the major causative factor in dental caries and has been known to induce dental caries by the process of initial attachment proliferation and acid production. The pH of Streptococcus mutans(S. mutans) media and glucosyltransferase(GTase) activity were determined to evaluate the anticariogenic activity of Dioscorea batatas and Prunella vulgaris hexane fraction. In the experiment of hexane fraction of Dioscorea batatas, the relative growth ratio(RGR) against Streptococcus mutans (S. mutans) was determined as 93% in concentration of 0.125 mg/ml, 100% in 0.25 mg/ml. The hexane fraction of Prunella vulgaris revealed relative growth ratio(RGR) against Streptococcus mutans (S. mutans) as 86% in concentration of 0.25 mg/ml, 100% in 0.5 mg/ml. The relative growth ratio(RGR) against of hexane fraction were determined as 92% in concentration of 0.25 mg/ml, 100% in 0.5 mg/ml. The acidities were pH 7.2 on Dioscorea batatas and 7.0 on Prunella vulgaris in 2.0 mg/ml in contrast to pH 5.6 on Dioscorea batatas and 5.2 on Prunella vulgaris in control. The inhibitory effect to activity revealed 35% on Dioscorea batatas and 25% on Prunella vulgaris in 2.0 mg/ml. The inhibitory effect of Dioscorea batatas was more potent than Prunella vulgaris.
