studies _ comparison of three methods of therapy I Table7 The drop-out rate was determined by the follow- ing parameters characterising a re-intervention and the end of observation: 258 cases of EX, 65 cases of RER, 37 cases of TR, and 15 cases of RV—seven of which were in connection with RER and five with TR. The last appointment was relevant for patients who did not undergo re-intervention. While EXs were distributed evenly over the obser- vationperiod,theotherfactorsdeterminingdrop-out accumulated in the first year post-RCT. The drop-out rate over the period and across the three therapies is shown in Table 7. _Discussion The present study has attempted to establish av- erage success and survival rates based on the same patients. The analysed cases were collected from the author’s general practice. Therefore, under the same research and evaluation conditions, the results of cross-sectionalstudiesasmirrorimagesofendodon- tic work in other practices, as described in literature, maybeexpectedfromthissuccessandsurvivalanaly- sis.
