Table 5 Average values (SD) of answers according to fatigue effect (Q1), treatment time (Q2), handling (Q3) and effectiveness (Q4 in %, separated for anterior teeth, premolars and molars) by the participants of the digitized training program (DTP) versus conventional training program (CTP) for Gracey curettes (GRA) and for sonic scaler (AIR)
Questions | DTP concept (Graetz et al. [11]) | CTP concept | Differences between groups of training concepts |
|---|---|---|---|
Q1 How did you feel scaling with the instrument? (1 = very tiresome/strenuous to 5 = extremely easy) | |||
GRA | 3.00 (1.05) | 2.56 (0.78) | p = 0.129 |
AIR | 3.27 (1.08) | 3.72 (1.02) | p = 0.132 |
Differences between groups of instruments | p = 0.32 | p = 0.007 | |
Q2 What was your sense of time when scaling with the instrument? (1 = highly time-consuming to 5 = highly time-saving) | |||
GRA | 3.34 (0.89) | 3.00 (0.69) | p = 0.067 |
