Analysis of Dental Personnel's Awareness and Educational Needs Regarding Digital Intraoral Scanners

Background: As the use of digital intraoral scanners (DIS) has expanded, the demand for digital capabilities is accelerating along with changes in the duties of dental hygienists. This study aimed to understand the actual use, awareness, and educational requirements of DIS among dental personnel. Additionally, it intends to provide foundational data to inform improvement plans for DIS education. Methods: This survey was conducted between March 2023 and April 2023 among 295 dental hygienists, dentists, and dental technicians working in dental institutions. The results are presented below. Results: Of the respondents, 96.3% were aware of the DIS, with 75.3% having experience with using it in various dental institutions where they worked. The response rate indicating that they received DIS training was 72.2%, but among them, only 20.7% had received training at a university, suggesting that the training experience rate is low compared to the DIS awareness rate, indicating a need for improvement. The average DIS awareness rating among respondents was 3.82 out of 5, with higher levels of awareness among dentists and dental technicians compared to dental hygienists. Furthermore, a correlation was noted where an increase in the education level corresponded to increased awareness. Among the 72.2% of respondents who had experience with DIS education, 70.0% had education provided by companies that produce and sell DIS products. The percentage of respondents who indicated that DIS education is necessary was found to be 93.2%, indicating that most research subjects recognized the need for DIS education. Additionally, 90.8% of respondents stated that a university-level curriculum related to DIS is necessary. Conclusion: In response to these developments, a digital dentistry curriculum, including the DIS, should be integrated into the dental hygiene curriculum, and continuous education should be provided post-graduation.
