Curriculum of gross anatomy education in Korean dental hygiene programs: Perceptions of clinical dental hygienists.

Abstract

It is essential for dental hygienists to have basic knowledge of gross anatomy to provide efficient treatment. However, gross anatomy course is relatively neglected due to their disparity from actual clinical dental practice. This study aimed to propose an effective dental hygiene gross anatomy curriculum that reflects the opinions of professional clinical dental hygienists. The study had an online-based cross-sectional design and the survey was distributed to clinical dental hygienists via social networks (n=200). The questionnaire consisted of questions on the utilization of anatomical knowledge in clinical practice, opinions on the contents and methods of gross anatomy education, and general characteristics. The present study found that 186 (93%) used anatomical knowledge at an above-average level. Qualitative analysis indicated that dental implant surgery, radiography, and extraction were the clinical procedures that required the most anatomical knowledge. The clinical dental hygienists answered that the most-necessary knowledge is that of the mandibular nerve, followed by that on the temporomandibular joint, mandible, maxilla, maxillary nerve, and masticatory muscle. The methods proposed to improvegrossanatomyeducation were (in decreasing order of importance) using videos or photographs (X-rays, CT, MRI, etc.), integrating education with clinical subjects, and using a three-dimensional visualization program. Higher education levels of respondents have increased their tendency to believe that the contents and methods of the presented education were necessary. Dental hygienists who utilized anatomical knowledge more often tended to be had a greater appreciation of the necessity of all educational contents and methods.
