Meanwhile, clinical dental hygienists who not completed geriatric-related courses had higher scores for, need for geriatric dental hygiene-related theoretical education, need for practice education with elderly people, and confidence in performing oral healthcare for elderly people. but, there was no significant difference (p >0.05). Conclusions: The results of this study showed that students and dental hygienists had high educational needs for geriatric dental hygiene.
