The job of dental hygienists is specialized, and they have to be capable of performing their primary duties including prevention of oral diseases, oral prophylaxis, and oral health education. To ensure their successful job performance, dentists should have an accurate understanding of their duties and need a change of mind-set about them. And there should be written legal and concrete regulations on the coverage of their work in order to let them boost their job performance with pride and a sense of responsibility. The purpose of this study was to examine the actual roles and job performance of dental hygienists in clinical field in an attempt to discuss the substantial job performance of dental hygienists and their job enlargement. It's basically meant to help enhance the efficiency and quality of medical services. The subjects in this study were 471 dental hygienists in dental clinics, dental hospitals, university hospitals and general hospitals across the nation, on whom a survey was conducted in person from March 2 to 25, 2005. The collected data were analyzed with SPSS Win 12.0 program, and the findings of the study were as follows: 1. The major jobs they currently performed included oral health education, hospital management, simple duties, extensive dental hygiene duties and joint treatment assistance. They hoped to continue to be responsible for oral health education, preventive treatment and extensive dental hygiene duties. 2. As for their current job by age, extensive dental hygiene duties, preventive treatment, joint treatment assistance, preserving treatment, prosthetic treatment and pediatric treatment were most conducted by the dental hygienists who were at the age of 26 to less than 31, and those who were at the age of 31 and up were most responsible for hospital management and simple duties. 3. As to job awareness by workplace, their workload was statistically significantly different according to their workplace. The hospital employees took care of more work than those in clinics. 4. Concerning job awareness by age, the younger dental hygienists suffered more role conflicts and were given a less free hand in work handling, the middle-aged group's job was uncertain. Legal regulations about the coverage of their work should be prepared in detail as a measure to stir up their responsible job performance and pride. In order to take advantage of experienced dental hygienists, their duties should be more differentiated and specialized, and their working conditions should be improved to boost their job satisfaction. That is, they should be given ample chances for promotion and serving as a middle manager and be given fair treatment according to their career. If their work is accurately darified and specialized based on career, it will boost the efficiency of dental treatment. Dental hygienists also should direct sustained efforts into self-development in order to become a skilled and professional oral health personnel.

The purpose of this study was to evaluate the effects of Photochemotherapy using a combination of erythrosine and standard halogen dental curing lights on the viability of Streptococcus mutans in the biofilm phase. To investigate the optimum treatment parameters, the researchers controlled the concentration of erythrosine, light irradiation time and the treatment time of erythrosine. The higher concentration of erythrosine (0, 10, 20, 40, 80 M) in the presence of light irradiation created greater effects in reducing the viability of S. mutans. The results showed a statistically significant difference among the antimicrobial effects in 20, 40, 80 M erythrosine. The higher irradiation time of light (0, 5, 15, 30, 60, 75s) in the presence of erythrosine showed greater effects in reducing the viability of S. mutans. There was statistically significant difference in 30, 60, 75 seconds. The higher treatment time of erythrosine (0, 1, 2.5, 5min) in the presence of erythrosine created greater effects on reduction of S. mutans viability. Statistically significant differences were found between 2.5 and 5 minutes of erythrosine treatment time. The results of this study showed that the photochemotherapy on S. mutans using erythrosine and the halogen dental curing lights conventionally used in dental clinics is effective in the condition of 20-40 M erythrosine concentration, irradiation time over 30 seconds, and erythrosine treatment time over 2.5 minutes.

Due to increasing demand for aesthetics, zirconia crowns have become a popular choice for treating primary molars. However, there is limited literature available comparing the survival rates of zirconia crowns with those of other restorative materials. The objective of this study was to compare the 36-month survival rates of zirconia crowns and stainless steel crowns for proximal caries, as well as to analyze failure types associated with each crown type. Electronic medical records and radiographs of 1,061 primary molars from 498 patients treated with 2 types of prefabricated crowns at Chosun University Dental Hospital and 2 private dental clinics between 2017 and 2019 were collected and analyzed. The survival rate of zirconia crowns was found to be lower compared to that of stainless steel crowns. Regarding the groups without pulp treatment, the survival rate of stainless steel crowns was significantly higher than that of zirconia crowns. However, in the groups that received pulp therapy, no significant difference in the survival rates was observed between the two preformed crowns. Notably, abnormal root resorption or periapical lesions were identified as the primary cause of restorative failure in stainless steel crowns, whereas loss of restoration was the predominant cause in zirconia crowns. This study holds valuable implications for clinicians when selecting preformed crowns for primary molars.

This study proposed a registered dentist model for the disabled based on consumer in-depth interview and supplier survey. This study proposed that dental clinics in the community take role as registered dentists for the disabled. Qualification screening and facility prerequisites are required to be selected as the registered dentists for the disabled and patients of the registered dentists were restricted to the disabled who can cooperate to dental treatment services with or without the aid of physical bondage. In order to encourage the participation in the program, subsidies for the registered dentists were necessary. Also, this study proposed financial supports for the medical expenses for patients at the same level as the current dental care center for the disabled. The registered dentist program for the disabled meets the needs of disabled consumers, such as accessibility of medical institutions, expertise of medical staff, and ongoing treatments with familiar medical staff. The registered dentist program for the disabled is expected to provide prevention and ongoing management for oral health promotion of disabled people and it also contribute to lower economic burden of oral health care of the disabled.
