Instrumentation kinematics had no impact on the intensity of postoperative pain. |
| Krithikadatta et al., 2016 | 152/152* | 147/147 | F and M | 18-55/36.5 | 33 | 114 | Two visit/Intracanal medication with Calcium Hidroxide | WaveOne/49/49* | Group 1: ProTaper/49/49 Group 2: Mtwo/49/49* | 5% NaOCl; Final irrigation: 17% EDTA and 2% Chlorhexidine | Teeth were not obtured | Teeth were not obtured, was temporary sealed with Cavit | Ibuprofen 400mg, if necessary | 2, 4, 6, 8, 12, 36 and 48h | WaveOne reciprocating files cause more postinstrumentation pain followed by ProTaper and MTwo. Reciprocating motion had a negative impact on immediate postoperative discomfort. |

Instrumentation kinematics had no impact on the intensity of postoperative pain. |
| Zand et al., 2016 | 90/90 | 90/90 | F and M | 19-59/33.5 | 90 | - | Single | Reciproc/45/45 | RaCe/45/45 | 17% EDTA gel-form + Saline Solution; Final irrigation: 2.5% NaOCl + saline solution | AH 26 Sealer | Lateral condensation/Temporary filling material | Unclear | 4, 12, 24, 48, 72h and 7 days | RaCe Rotary systems, resulted in less severe postoperative pain compared to the Reciproc files. Reciprocating motion had a negative impact on immediate postoperative discomfort. |
