A total of nine oral health educators for 17 persons with developmental disabilities conducted oral health education once a week for four weeks. The oral health educators provided oral health knowledge education and individual toothbrushing teachings. The developmentally disabled people in their 20s and 30s conducted oral health education without a guardian. Ten people who completed all the four pieces of training had no significant improvement in the toothbrushing method and the recommended number of toothbrushing sessions a day, as well as a lack of growth in oral health knowledge. However, 58.8% of the individuals expressed satisfaction with the oral health education program, whereas, 52.9% expressed the desire for a re-education. Although the ratio of teachers to students was 1:2, and the oral health education conducted four times, it was insufficient to promote a successful oral health behavior or knowledge for people with developmental disabilities. Therefore, as a suggestion, oral health education for people with developmental disabilities ought to proceed with their guardians to promote the success of the training.

Objective: The purpose of this study was to analyze the Cone-beam computed tomograghy(CBCT) scan of endodontically treated maxillary first molars and investigate how second mesiobuccal (MB2) canal is treated, how the prognosis of mesiobuccal (MB) root is different compared to other roots and the prognosis factor on apical periodontitis. Methods: Subjects were endodontically treated maxillary first molars whose were collected from CBCT scans taken from January 2018 until December 2019. A total of 525 maxillary first molars were analyzed by an endodontist to determine the presence of the MB2 canal, the quality of the root canal filling, and the presence of apical periodontitis. The chi square test and Fisher's exact test was used to examine the relationship between each variable. Results: MB2 canals were found in 46.3%, of which 76.5% were not treated. The more main canal of mesiobuccal root (MB1 canal) was well filled, the more significantly MB2 canal was well filled (p<0.001). The apical periodontitis of MB root was not related to the filling quality of MB1 canal (p=0.370) and was related to the filling quality of MB2 canal (p=0.004). The apical periodontitis of MB root was related to the quality of canal filling of MB2 canal and the apical periodontitis of DB and P root. Conclusions: It was found that the majority of MB2 canals were not treated. The apical periodontitis of MB root was analyzed to be related to the quality of canal filling of MB2 canal. The apical lesion of the MB root was not correlated with the treatment of the MB1 canal, but it was significantly related to the quality of filling of MB2 canal.

Introduction: The legal duties of Korean dental hygienists are different from the actual tasks. These factors cause dental hygienists to experience work stress. Therefore, it is necessary to investigate what tasks the dental hygienist expects to perform. Methods: This study examined the perception of dental hygienists' work on 158 prospective graduates of the 3rd-year and 4th-year course of dental hygiene. The questionnaire about the dental hygienist's duties was prepared based on the job description of dental hygienists by the Korea Health Personnel Licensing Examination Institute. Results: More than 84% said that all of the work in the second job description was possible as dental hygienists. subjects responded that the following items were not dental hygienists' duties: treatment plan based on medical history and dental history, treatment plan based on an intraoral and extraoral examination, treatment plan based on the results of teeth and periodontal examination, analysis of oral health data in community, planning of oral health promotion in community, planing of water fluoridation, reading of radiography, root planing, physical treatment on head and neck, using an ultrasonic device on head and neck, dealing with laser devices, making a temporary crown, suture and stitch-out, and intramuscular injection. Conclusions: Most graduates of dental hygiene departments have recognized that the tasks described in the second job description are dental hygienists' work; therefore, it is necessary to improve the gap between expected work and legal work.

Although tobacco use has been known as one of the biggest risk factors on periodontal health, little is known about the effect of smoking cessation on it. The aim of this study was to investigate the change of concentration of matrix metalloproteinase (MMP)-8, MMP-9 and interleukin (IL)-1꺬 in gingival crevicular fluid (GCF) of 11 quit-smokers for 1 year after smoking cessation. Eleven male subjects to maintain quit-smoking for 1 year participated the oral examination, GCF and saliva collection without periodontal treatments at baseline, after 2 weeks, 2 months, 4 months, 6 months and 1 year. To confirm quit-smoking, nicotine and cotinine concentrations in saliva were measured by high performance liquid chromatography. MMP-8, MMP-9 and IL-1꺬 concentrations in GCF of upper anterior teeth area were measured by enzyme-linked immunosorbent assay. Change of MMP-8 in GCF during smoking cessation showed fluctuation with decrease (5 subjects) or increase (2 subjects) or maintenance tendency (4 subjects). Changes of MMP-9 were decrease (6 subjects), or increase (2 subjects), or maintenance (3 subjects). Change of IL-1꺬 also showed fluctuation with decrease (5 subjects) or increase (3 subjects) or maintenance tendency (3 subjects). The subjects with increase tendency had the relatively smaller amount concentration of MMP-8 and MMP-9 at the baseline. It was unclear smoking cessation without periodontal treatment could affect MMP-8, MMP-9, and IL-1꺬 in GCF. Fluctuation of periodontal biomarkers during smoking cessation might result from feedback interaction between environmental factors and periodontal cells.

This study focused on examining the aesthetic aspects of Eungje-Eobyong-sixty-two poems(應製御屛六十二詠) by Jebong, Go Gyong-myong. It is a collection of pictorial poetry, poetry of spiritual beings, and poetry written by the order of the king. King Myongjong showed 62 scrolls of paintings he had collected to Jebong and ordered him to write poetry about them. That is, it was a solo project executed by the order of the king. The paintings show flowers, grass, trees, insects, fish, birds, and other animals. In particular, as many of them display birds, the poetry described diverse types of birds dynamically. The following is a summary of it: First, this study examined the background and meaning of the poetry focusing on its epilogue. As a result, the characteristics and meaning of the poetry as pictural pieces were discovered. In particular, the royal family's interest in the aesthetic aspects and relationships between the king and Jebong were understood. Then, through expressive methods, the aesthetic aspects of poetry by Jebong were revealed. Through this content the descriptions of spiritual beings, nobles and solemn beauty was examined. The dynamic status, which was well-captured in the paintings, was properly detailed in the poetry. The vivid realism was well layed out in it. Therefore, the natural aestheticism in poetic expression was impressive. Finally, the parodic beauty was made vivid through innovative concepts. Jebong's poetry was not only faithful only to the paintings but he also reinterpreted the paintings through his aesthetic sense. That is, he exerted his aesthetic emotions as well as expressive power for the paintings with the addition of creative ideas. Therefore, he criticized the contemporary status of his society sharply and was aware of it through parody. In conclusion, this study explained solemnity, nature, and parody as aesthetic characteristics of Eungje-Eobyong-sixty-two poems(應製御屛六十二詠) by Jebong.
