Pain Index after endodontic treatment

[摘要] Introduction: Predicting the onset of pain after endodontic treatment favors the professionals'clinical judgment regarding this procedure. Objective: To construct an index that combines the factors associated to pain afterendodontic treatment in the study population. Methods: A study was carried out in two stages, in Santo Domingo City, Villa ClaraProvince. The first stage was a cross-sectional analytic study over a randomsample of 94 endodontic treatments, collected in the period of March to Decemberof 2015, for the construction of the index. The second stage was also a cross-sectionalstudy over a sample of 62 treatments, carried out between January and May, 2016,with the purpose of assess the discriminatory ability of the obtained index.The information was collected through interrogation, clinical and radiographicexamination; the presence of pain after therapy was recorded. The data wereanalyzed using descriptive and inferential statistics. For the constructionof the index, we obtained the Cramer's V statistic values ​​ofeach variable. Results: Among the factors associated with pain after endodontic treatment pain,the most were described such as preoperative pain or inflammation, pain duringtreatment, the number of appointments, and a reduced root canal, with Cramer'sV values of 0.848, 0.605, 0.595 and 0.592, respectively. The sensitivity ofthe proposed index was 83.3 %. Conclusions: In the studied population, a multi-causal relationship was observed inthe factors associated with the presence of pain after endodontic treatment.The preoperative pain or inflammation was the most influential factor. Thisfactors were synthesized by means of an index. The proposed index presents anadequate sensitivity, which contributes to establish more accurate judgmentsregarding the subsequent onset of pain.
