Abstract
This study was conducted to investigate the treatment outcomes of root canal treated teeth with apical periodontitis which were treated either non-surgically or by means of endodontic microsurgery and assessment of factors such as presence/absence of intra-radicular posts, clinical and demographic factors on outcome of treatment modality adopted. The data comprising of clinical and radiographic record of 398 patients with previously root filled teeth and periapical periodontitis with follow-up period of more than 11 months were included in the study. Non-Surgical cases were evaluated using the peri-apical index (PAI) sub-divided into 3 groups i.e., success, uncertain and failure at control. Similarly, surgical cases were assessed using Molven/Rud’s criteria distributed into 3 sub-groups i.e., success, uncertain and failure at control. The results of present study showed that the patient’s underage of 50 years (88.67%) and above 50 years (76.96%) preferred NSRT over EMS (11.3% & 23.04%) whereas, the percentage of EMS was greater in patients >50 years (23.04) compared to <50 years (11.33). The success rate of surgical endodontic procedures was significantly higher than that of non-surgical treatment (p =.035). Conversely, the subgroups of teeth that had posts tended to do somewhat better following non-surgical therapy as opposed to surgical treatment (p =0.111). There was a significant difference (p =.018) favouring surgical treatment for subgroups without a post. These results concluded that compared to non-surgical retreatments, this study indicated that surgical retreatments had a better success rate. On the other hand, non-surgical retreatments, as opposed to surgical retreatments, typically yielded superior results for teeth with intra-radicular posts.
