Description
Laura Glevitzky and co-authors compare, in 2026, spread-out versus block-scheduled practical training for dental students learning to clean below the gumline. A German licensing reform compressed the training, so the team compared 102 students across old and new curricula on manikin teeth after training and again after their first real patient course.
Students on the older, distributed schedule removed simulated plaque about five percentage points better and calculus at twice the adjusted odds, with equal treatment time. Both groups later worked about a minute per tooth faster in clinic while accuracy slipped, a speed-accuracy trade-off confirmed in the subgroup measured twice. Magnification users, concentrated in the new cohort, did not explain the gap; removing them widened it. Pass rates still exceeded 86 percent under both schedules.
