Objectives: As the school-age population continues to decline in Korea, the consolidation and abolition of departments continues with the economic logic. This study aimed to analyze the relative competitiveness of the department of dental hygiene and to investigate the effectiveness of the YouTube platform being used to promote admission. Methods: Using the admission result data provided by the Korea council for university education, the new student competition rate and recruitment rate of the department of dental hygiene were compared with those of the departments of natural sciences and all other departments. Also, the effect of YouTube channel operation on them was analyzed. Results: The department of dental hygiene showed a slight advantage but it was not particularly the case compared to other departments of natural sciences.
The promotion using YouTube did not have any significant effects. Conclusions: Considering that the school-age population will rapidly decrease in the future, more active strategies are needed.
