Abstract
This study aimed to evaluate the impact of errorless and errorful learning, on acquisition of root canal hand-instrumentation skills. Dental students prepared standardised canals of different diameters and curvatures. Learning involved minimising (errorless: n=21) or maximising errors (errorful: n=21). Students who had completed accredited pre-clinical activities provided comparative data (n=17). During testing, the distal canal of a plastic mandibular molar was prepared, first as a single task and then under multi-tasking conditions. Performance was assessed by preparation accuracy and time. Differences were assessed using anova (P<0.05). Performance in the experimental groups was similar during learning. When multi-tasking, errorful learners showed a deterioration in preparation accuracy (P<0.05). In contrast, preparation accuracy and completion times for the errorless and comparative groups remained stable when multi-tasking. Errorless learning resulted in stable performance under multi-tasking conditions. Investigation of alternative approaches to learning motor skills in dentistry is warranted as such approaches may provide better outcomes, especially under demanding conditions.
