Figure 3: Evolution of drilling outcomes with simulator training. (a) Mean position difference. (b) Mean angulation deviation (mean of deviations for both buccolingual and mesiodistal angulations). (c) Mean drilling depth. (d) Perforation (percentage) per trial. (e) Mean drilling duration. (f) Mean total duration. Results are expressed as m ± SEM, . versus 1st trial.
