Abstract Background: Dental caries remains a major public health issue worldwide, particularly among children. Pit and fissure sealants represent a high-quality, evidence-based preventive measure. However, ensuring the reliability of their application by newly graduated intern dental students trained through tele-education remains an emerging area of growing interest. Objective: To evaluate the clinical success rate of pit and fissure sealants placed by intern dental students following tele-demonstration training versus traditional training approaches. Methods: This randomized controlled trial involved 100 mandibular first permanent molars in 50 children aged 7 to 9 years, treated by 20 dental interns assigned to two groups using a split-mouth design. One group received direct clinical demonstration, while the other received tele-education via a pre-recorded video. Sealant retention and marginal discoloration were assessed after a 3-month period.
