Background: The number and curriculum of dental hygienists in Korea have dramatically increased. Controversies have since resulted from insufficient job descriptions of the work performed by a dental hygienist. A dentist's perception was examined to legally reflect the actual work of dental hygienists. Methods: Four hundred and nineteen dentists were surveyed about the duties of a dental hygienist. Their views on the career and availability of each job were examined. The duties of the dental hygienist include 13 items in dental treatment preparation, 14 items of radiography, 21 items of preventive dentistry, 6 items of periodontal treatment, 12 items of oral medicine, 12 items of conservative dentistry, 8 items of prosthetics, 10 items of orthodontics, 7 items of oral and maxillofacial surgery, 6 items of implantation, 6 items of impression taking and model fabrication, 5 items of anesthesia and injection, 11 items of management and administrative, and 3 items of self-development. Results: Most of the duties were doable by a dental hygienist. Many dentists reported that managing implants, oral hygiene of special patients, some duties in oral medicine, teeth brightening, making temporary crowns, making individual trays, selecting shades, ligaturing, and precision impressions need ≥3 years of experience. Duties perceived by dentists not to be performed by dental hygienists were reading radiographs (55.4%), suture and stitch out (48.0%), intramuscular injection (36.0%), root planning (27.2%), cementation and removal of prostheses (23.2%), and examining pulp vitality (22.0%). Conclusion: Current laws are to be revised to include, the care provided by dental hygienists and under a physician's supervision. Flexibility is also needed to cope with rapidly changing dental technology.
Purpose: This study conducted a survey on the elderly with physical debilities, who are in a medically vulnerable social class, to examine closely their demo-sociological characteristics, unmet needs, dental states, and living qualities and satisfaction levels relating to oral health and social supports to them, and also to prepare the basis for effective public medical policies and health improvement programs aimed at improving the quality of life for the elderly with physical debilities. Methods: Twenty-two elderly care facilities within Jeju Special Self-Government Province participated in the survey. Between 11 January and 5 March 2010, a total of 250 elderly persons(65 and over) with physical debilities were interviewed and their dental health was checked. Results: The results of the survey are as follows. The need for social support for dental care of the elderly with physical debilities was high in the medical institution-supported service (49.6%). The unmet needs for physical care were high in bathing (49.6%) and using public transportation (71.6%). More than half of these surveyed had ten or fewer teeth. The survey found that 31.6% of the participants experienced problems eating, due to poor dental health. Concerning quality of life, 30.5% of those surveyed experienced physical pain. Conclusion: In summary, the ages of the survey participants directly relates to the degree of behavioral debility experienced. The more debility a participant exhibits, the greater is the need for social support and dental care. The dental health of a participant directly relates to a higher quality of life. Good dental health of a participant translate to better quality of life. In light of the fact that the elderly with physical debilities suffer from a lack of accessibility to medical care and worse oral health than do other elderly persons, it is essential to increase accessibility to medical institutions that can provide such services as door to door dental care. Current insurance policies, funding for denture insurance, and free denture and denture-upgrade programs desperately need to be expanded. Therefore, to improve effectively the quality of life for the elderly with physical debilities civil dental medical resources should be encouraged to provide inclusive and prevention-focused medical care. In the public domain, door to door dental care services and cooperation with civil dental care resources need to be improved to increase impartial accessibility to dental medical institutions.

The aim of this retrospective study was to evaluate the demographic characteristics of pediatric dental patients who underwent dental treatment under general anesthesia (DTGA) at the Seoul National University Dental Hospital from January 2011 through December 2020 and compare the patterns of repeated DTGA between dental patients with severe disabilities (DSD) and non-DSD (healthy or medically compromised patients without DSD). There were 1,857 DTGAs among 1,719 patients (mean age = 5.1 years; males = 59.3%; ASA 2 or above = 52.9%; DSD = 26.8%). Overall, 6.6% of patients underwent repeated DTGA, and the rate of repeated DTGA over a 10-year period was 7.4%. ASA 2 or above (p < 0.0001) and DSD (p < 0.0001) were more likely to undergo repeated DRGA compared to ASA 1 and non-DSD. At both GA1 and GA2, DSD received significantly more restorative treatment on permanent teeth than non-DSD (p = 0.002, p < 0.0001, respectively). There has been an increasing demand for DTGA in pediatric dentistry over the last 10 years. Regular check-ups and preventive oral health care are necessary for pediatric dental patients with severe disabilities to reduce the possibility of repeated DTGA.
This article discusses accomplishments and historical implications of American missionary dentist W.J. Scheifley and the first Korean dental department, which was established in 1915 in Korea. W.J. Scheifley, with Christian service mind and mission as a dentist, applied to American Protestantic missionary dentist overseas. The dental department in the Severance Union Medical College introduced the scientistic dental education of America, facilitated research on the dental condition of the Korean people, and ran independent dental clinic. W.J. Schiefley criticised the profit-seeking attitude of Japanese dentists and denturist(="IPCHISA", in Korean pronunciation) and emphasized on the significance of Oral Health. He did all kind of dental treatments with advanced equipments like X-ray machine, and managed the collective oral health care for missionaries overseas. He trained medical students and assistants of the dentists with the goal of producing Korean dentists, but he failed due to the Dentist law introduced by Japanese colonial administration that interfered with producing Korean dentists. However, O.R. Avison's proposal of the establishment of dental schools stimulated the establishment of Kyungsung dental school, which provided the basis for the Dental department in the Severance Union Medical College becoming special training institution for Korean Dentists.
Although there are many different ways that restorations can be made, it can be said that the biocompatibility of abutment and crown is very important in this experiment. When placed in the actual oral cavity, the differences were obvious. Compared to In-ceram Aluminium, the structure that is obtained after firing reveals a particularly homogeneous distribution of the crystal and glass phase. The In-ceram aluminium system had many problems, such as having weak tensile strength, and having low bonding strength due to the shrinking that occurs after firing. Because of the opaque finish of the metal frame, the two may look similar from the outside, but it is evident that there are differences between using a metal frame and In-ceram. VITA VM9 has been designed as a special ceramic featuring a fine structure or stabilized Zro2 substructures, and so the VITA VM9 excels in its light refraction and reflection behavior, which is similar to natural teeth. It also has outstanding chemical balance, which presents advantages such as considerably reduced accumulation of plaque on the ceramic surface.? This ultimately results in easier care and cleaning for the patient.
To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.
This study was done to recognize the importance of errors in measurements of cephalometric radiograph and to find the anatomical structures those need special care to select as a reference points through the detection of the systematic errors and estimation of random errors. For this purose, 100 cephalometric radiographs were prepared by usual manner and 61 reference points, and 130 measurement variables were established. Measurement errors were detected and estimated by the comparison of the 25 randomly-selected samples for repeated measurements with the main sample. The following results were obtained : 1. In comparison of the repeated measurements, there were statistical significant differences in 24 variables which were 18.4% of 130 total variables. 2. The frequency of the difference in identification of the reference points between the repeated measurements was very high in the root apex of upper incisor(as), the most posterior wall of maxilla(tu), soft tissue nasion(n'), soft tissue frontal eminence(ft), and ad3 in airway. 3. After correction of reference points marking until the level of below 5% significance, the range of random errors were from 0.67 to 1.71 degree or mm. 4. The variable shown the largest random error was the interincisal angle(ILs-ILi). 5. Measurement errors were mainly caused by the lack of precision in anatomic definitions and obscure radiographic image. From the above results, the author could find the high possibility of errors in cephalometric measurements and from this point, we should include error analysis in all the studies concerning measurments. In is essential to have a concept of error analysis not only for the investigator but also for a reader of other articles.
Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.
Objectives: The present study was undertaken to study the maternal risk factors for preterm birth (PTB) and low birth weight (LBW) with a special emphasis on assessing the proportions of maternal genitourinary and periodontal infections among Indian women and their association with adverse pregnancy outcomes. Methods: A hospital-based prospective study comprising 790 pregnant women visiting the obstetrics clinic for a routine antenatal check-up was undertaken. Once recruited, all study participants underwent clinical and microbiological investigations for genitourinary infections followed by a dental check-up for the presence of periodontitis. The study participants were followed up until their delivery to record the pregnancy outcomes. Infectious and non-infectious risk factors for PTB and LBW were assessed using univariate and multivariate Cox regression analysis. Independent risk factors for PTB and LBW were reported in terms of adjusted relative risk (ARR) with the 95% confidence interval (CI). Results: Rates of PTB and LBW in the study population were 7.6% and 11.4%, respectively. Previous preterm delivery (ARR, 5.37; 95% CI, 1.5 to 19.1), periodontitis (ARR, 2.39; 95% CI, 1.1 to 4.9), Oligohydramnios (ARR, 5.23; 95% CI, 2.4 to 11.5), presence of Nugent's intermediate vaginal flora (ARR, 2.75; 95% CI, 1.4 to 5.1), gestational diabetes mellitus (ARR, 2.91; 95% CI, 1.0 to 8.3), and maternal height <1.50 m (ARR, 2.21; 95% CI, 1.1 to 4.1) were risk factors for PTB, while periodontitis (ARR, 3.38; 95% CI, 1.6 to 6.9), gestational hypertension (ARR, 3.70; 95% CI, 1.3 to 10.8), maternal height <1.50 m (ARR, 2.66; 95% CI, 1.3 to 5.1) and genital infection during later stages of pregnancy (ARR, 2.79; 95% CI, 1.2 to 6.1) were independent risk factors for LBW. Conclusions: Our study findings underscore the need to consider screening for potential genitourinary and periodontal infections during routine antenatal care in developing countries.
