RESUMEN
INTRODUCTION: Undergraduate dental curriculum consisting of digital tools is essential in today's era of modern dentistry. The aim of this study was to evaluate final-year undergraduate dental students' perception of using intraoral scanners and the feasibility of increasing exposure to intraoral scanners in their undergraduate programme. MATERIALS AND METHODS: Forty students volunteered to complete one maxillary conventional and optical impression (TRIOS 3, 3Shape A/S). Questionnaires were used to assess their familiarity, perceived confidence levels, difficulties and user-friendliness of each technique using a visual analogue scale prior to and after experiencing each impression technique. RESULTS: Students felt more familiar with conventional (C) than digital (D) impressions (P = .00). Their pre-confidence level was also higher with the conventional method (C: 80.9 ± 15.5; D: 39.6 ± 25.5); however, the post-confidence level significantly increased for the digital impression technique (P = .00). Participants perceived conventional technique to be easier (P = .02) and faster than optical impressions (P = .03). User-friendliness of the intraoral scanner scored moderate (67.7 ± 22.9). The difference in the mean total working time was not significant (P = .05). Forty per cent of participants indicated that they preferred using the digital impression technique. CONCLUSIONS: Although final-year undergraduate students still perceived the conventional impression technique to be easier and faster than digital scanning, there was a significant increase in the level of confidence by this cohort after only one occasion of clinical optical impressions. Undergraduate dental students are ready to uptake new technology, and it should be strongly considered to incorporate more digital scanning during their training.
