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.
Interventions
PROCEDUREGlass ceramic onlay preparation
The participants engaged in two practice sessions, each lasting two hours. They either started with their dominant hand followed by non-dominant hand or practiced solely with their non-dominant hand. Each participant prepared a mandibular left first molar resin typodont fixed to the table for a glass ceramic onlay restoration. Preparation was conducted extraorally.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Onlay preparation score | 3 hours | Onlay preparation criteria using Rubic scale, assessed by the student self-assessment and one prosthodontic staff. The higher score indicates better performance of the student |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Qualitative measurement by focus group interview | 1 hours | Focus group interview based on the semi-structural questionnaire regarding individual perception on the onlay preparation during practice and test sessions. |
