Purpose: Dental floss clip (DFC) traction-assisted endoscopic submucosal dissection (ESD) is widely performed owing to its simplicity. This study aimed to clarify the appropriate indications for the DFC traction method in early gastric cancer when ESD is performed by less-experienced endoscopists. Methods and Methods: We retrospectively analyzed 1,014 consecutive patients who had undergone gastric ESD performed by less-experienced endoscopists between January 2015 and December 2020. Gastric ESD was performed without DFC in all cases before December 2017 [DFC (-) group, 376 cases], and ESD was performed with DFC in all cases after January 2018 [DFC (+) group, 436 cases]. The procedure time and rates of en bloc resection, complete resection, and adverse events of the groups were compared. Results: The procedure time did not differ significantly between the 2 groups. However, when comparing lesions >20 mm, the procedure time in the DFC (+) group was significantly shorter than that in the DFC (-) group (95±46 vs. 75±31, P<0.01). The procedure time for lesions located in the greater curvature of the upper or middle stomach and lesions >20 mm located in the lesser curvature side of the stomach in the DFC (+) group was significantly shorter than that in the DFC (-) group. Conclusions: The indications for DFC during gastric ESD by less-experienced endoscopists include lesions located in the greater curvature of the upper or middle stomach, and lesions >20 mm located in the lesser curvature of the stomach.

Objectives: This study analyzed the relationship between dietary behavior and health-related characteristics and experiences of major oral disease symptoms using online raw data on adolescent health behavior. Methods: Using the raw data on 61,858 adolescents collected through the 13th Adolescent Health Behavior Online Survey, a complex samples logistic regression analysis was conducted to assess risks of major oral diseases. Results: The less one consumes sweet drinks and the more one eats vegetables per day, the less likely one is to experience symptoms of tooth decay and periodontal diseases. Undergoing scaling and oral health education help prevent major oral diseases. Brushing after school lunch prevents periodontal diseases and foul breath, and using dental floss and interdental brush also help prevent periodontal diseases. Conclusions: To minimize experiences of oral diseases during adolescent years, it is necessary to periodically scale teeth and provide knowledge regarding the personal management of dental plaque through school oral health education.

Objectives : The purpose of this study was to examine the awareness-perception factors and oral health promotion behavior of dental hygiene and nonhealth-related students in an effort to find out factors affecting their oral health promotion behavior. Methods : The subjects in this study were students in the three-year-course dental hygiene and students in the two-year-course nonhealth-related department in G college located in the city of Gwangju. After a survey was conducted, the collected data were analyzed and compared. Results : 1. The dental hygiene students were statistically significantly ahead of the nonhealth-related students in perceived oral health knowledge(p<0.001), awareness of the importance of oral health(p<0.001), perceived oral health status(p<0.001) and oral health interest(p<0.001). 2. Concerning the characteristics of oral health promotion behavior, the dental hygiene students were statistically significantly better at toothbrushing(p<0.001) and the use of dental floss(p<0.001) than the nonhealth-related students. 3. Regarding factors affecting oral health promotion behavior, oral health knowledge and oral health interest were identified as the factors that impacted on oral health promotion behavior. Out of the two, oral health interest exercised a greater influence on that. Conclusions : It seems that oral health education could motivate students to be concerned about their oral health, to acquire knowledge on that and eventually to change their oral health behavior and attitude. As for college students, oral health education provides a final chance for them to check their oral health knowledge, attitude and oral health promotion behavior before they start to work as full-fledged adults, and institutional measures should be taken to offer more intensive official oral health education.
