Improving the Communication of Dental Findings in Pediatric Dentistry by Using Intraoral Scans as a Visual Aid: A Randomized Clinical Trial

The aim of this first randomized clinical trial (RCT) was to determine whether intraoral scans (IOS) can be used as a visual aid to improve the communication of dental findings in pediatric dentistry. Therefore, 60 children (mean age 10.1 ± 3.3 years) and their accompanying parents/primary caregivers (PGs) were examined between July 2022 and February 2023. Patients were randomly allocated to two groups: half of the participants were informed of the children’s dental findings including treatment plans by verbal explanation alone (control group, n = 30), while the other half were informed using IOS (Trios 4, 3Shape) as a visual aid to support the verbal explanation (study group, n = 30). Both groups then completed a questionnaire regarding their children’s diagnosis, treatment needs, planned therapy, and oral hygiene. Statistical analysis was performed using a t-test (p < 0.05). Overall, there was a significant difference between the two groups (p < 0.001) in terms of understanding the current oral situation of their children. While 85.5 ± 17.3% (mean ± standard deviation) of the answers were correct in the study group, only 57.2 ± 17.8% of the participants in the control group
