Abstract
Abstract

Backgrounds
Despite the rapid development of digital dentistry, the use of digital intraoral scanners remains limited. The aim of this study was to evaluate the changes in views on intraoral scanners among dental hygienists after training.


Methods
Thirty-four dental hygienists with >3 years of clinical experience participated and were divided into 2 groups : iTero and Trios groups. Participants of each group practiced the usage of both intraoral scanners, for total 12 times over 4 sessions, Questionnaires were given to participants at two different times; prior to and after the completion of the training sessions. The parameters of questionnaires included on difficulty of use, patient discomfort, awareness, preference, and clinical usefulness of intraoral scanners and comparison of two types of scanners.


Results
Upon the completion of the training, both iTero and Trios groups gave positive feedback on anticipated accuracy, efficiency, and clinical usefulness. More participants of the iTero group responded that the level of difficulty of use and patient discomfort was greater than Trios. Both groups preferred Trios for its clinical usefulness.


Conclusions
The perceptions of dental hygienists on usage of intraoral scanner and digital impression improved positively with the training. The participants favored Trios over iTero in terms of difficulty of use , patient comfort, and clinical usefulness. This study showed that appropriate training could change the views on the efficiency of intraoral scanners positively among dental hygienists.
