About this study
Official title: Influence of Sequential Practicing for Psychomotor Skill Acquisition of Non-dominant Hand in Undergraduate Dental Students: A Randomized Controlled Trial With Qualitative Approach
To determine the influence of hand practice sequence on psychomotor skill acquisition in a glass ceramic onlay preparation among undergraduate dental students.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Glass ceramic onlay preparationProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Left: dominant - non dominant | Experimental | 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. Receives: Procedure: Glass ceramic onlay preparation |
| Left: non dominant | Active comparator | 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. Receives: Procedure: Glass ceramic onlay preparation |
| Right: dominant - non dominant | Experimental | 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. Receives: Procedure: Glass ceramic onlay preparation |
| Right: non dominant | Active comparator | 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. Receives: Procedure: Glass ceramic onlay preparation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Onlay preparation score
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
Measured: 3 hours
Secondary outcomes (1)
Qualitative measurement by focus group interview
Focus group interview based on the semi-structural questionnaire regarding individual perception on the onlay preparation during practice and test sessions.
Measured: 1 hours
