Brief Summary

To determine the influence of hand practice sequence on psychomotor skill acquisition in a glass ceramic onlay preparation among undergraduate dental students.

Detailed Description

Effect of bilateral transfer practice on psychomotor skill acquisition among dental students remains unresolved. Bilateral transfer assumed that training one side of the body can also improve performance on the other side. Eligible participants are fourth- to sixth-year undergraduate dental students at the Faculty of Dentistry, Chulalongkorn University during the 2024 to 2025 academic year. The participants were categorized as left- or right-handed based on self-reporting. Participants enrolled two-day study with one-week separating inverval. On the first day, they learn a video presentation on glass ceramic onlay preparation followed by two practice sessions with 2-hour within each session. The practice start with either using non-dominant or dominant hand, followed by the use of non-dominant hand. One week later, they enroll two-hour practical examination on glass ceramic onlay preparation using their non-dominant hand. No practice is allowed during one-week separating interval.
