This randomized controlled trial compared pit and fissure sealants placed by dental interns after direct clinical demonstration or tele-education using a pre-recorded video. The split-mouth study included 100 mandibular first permanent molars in 50 children aged 7 to 9 years. At 3 months, sealant retention and marginal discolouration did not differ significantly between training groups (p = 0.766 and p = 1.000, respectively). The tele-education group had a slightly higher relative risk, which the authors judged not clinically significant.
Key findings
- Sealant retention showed no statistically significant difference between direct demonstration and tele-education (p = 0.766).
- Marginal discolouration did not differ significantly between groups (p = 1.000).
- The tele-education group had a slightly higher relative risk, but the difference was not clinically significant.
Why it matters
The findings suggest that a pre-recorded tele-demonstration can support intern training in a preventive dental procedure without an observed short-term disadvantage in sealant retention or marginal discolouration. This is relevant to educational settings considering remote instructional tools, while the results concern a specific procedure, trainee group, and follow-up period.
What to keep in mind
Outcomes were assessed after only 3 months, so the study does not establish longer-term sealant performance.
