| dc.description.abstract | Although there have been many studies concerning endodontically treated teeth (ETT) and the factors affecting prognosis, many have reported different findings. This retrospective study aimed to support the hypothesis that the initial pulpal diagnosis and restorative factors can help determine the prognosis of ETT. The University of Manitoba’s data collecting software was used to assess 1,360 ETT from January 2011 to June 2021, a period of 10 years. A Kaplan-Meier survival estimate with an associated P value comparing different prognosis, types of posts, and restorations, respectively, was performed using SPSS statistical software. From this data pool, there was a 94.4% survival rate of ETT with only 5.6% failing. A pre-operative necrotic pulp diagnosis was determined to be clinically significant in affecting prognosis. In descending order, a full coverage crown proved to improve prognosis, then permanent restorations, then temporary restorations. Other factors such as the presence of a post, type of post, amalgam vs composite, and type of crown did not affect prognosis. In descending order of causing failure in ETT, reasons were: 33.33% non-restorable crown fractures, 25% vertical root fractures, 14.29% inadequate restorations, 10.71% periodontal reasons, 9.5% endodontic failure, and 7.14% non-restorable caries. Based on these results, it was concluded that just as the quality of endodontic treatment is important, so is the quality/type of restorations that follows. Based on this paper, patients should be recommended full coverage crowns after endodontic treatment to ensure the best prognosis. | en_US |
