Study Overview
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.

Arms & Interventions
Left: dominant - non dominant
The left-handed participants in this arm started practicing a tooth preparation for a glass ceramic onlay using their dominant left hand during the first practicing session, followed by non-dominant right hand during the second practicing session. Each practice session is limited to 2 hours.
Intervention: Glass ceramic onlay preparation (Procedure)
Left: non dominant
The left-handed participants in this arm practicing a tooth preparation for a glass ceramic onlay using their non-dominant right hand for both the first and second practicing sessions. Each practice session is limited to 2 hours.
Intervention: Glass ceramic onlay preparation (Procedure)
Right: dominant - non dominant
The right-handed participants in this arm started practicing a tooth preparation for a glass ceramic onlay using their dominant right hand during the first practicing session, followed by non-dominant left hand during the second practicing session. Each practice session is limited to 2 hours.
Intervention: Glass ceramic onlay preparation (Procedure)
Right: non dominant
The right-handed participants in this arm practicing tooth preparation for glass ceramic onlay using their non-dominant left hand for both the first and second practicing sessions. Each practice session is limited to 2 hours.
Intervention: Glass ceramic onlay preparation (Procedure)
Outcomes
Primary Outcomes
Onlay preparation score
Time Frame: 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 Outcomes
- Qualitative measurement by focus group interview(1 hours)
