Clinical researchRelationship between Postendodontic Pain, Tooth Diagnostic Factors, and Apical Patency
Section snippets
Materials and Methods
This research was conducted with the approval of the Ethics Committee of Clinical Research of Saint Carlos Hospital-Madrid.
Three hundred endodontic treatments were performed in uniradicular, biradicular, and multiradicular teeth by one endodontist, all of them in single visits. All patients were informed of the aims and design of the study, and written authorizations were obtained before their inclusion.
Exclusion criteria were the need for retreatment, pregnancy, failure to obtain patient's
Results
Results are shown in TABLE 1, TABLE 2, TABLE 3.
Discussion
One of the main problems in studying pain is the patient's subjective evaluation and its measurement. For this reason, design of the questionnaire is critical and must ensure that it will be fully understood by patients and easily interpreted by researchers.
In this report, a simple verbal categorization was used in the feedback form with 3 categories: mild, moderate, and severe. These categories were straightforwardly understood by patients and were defined by the presence or absence of the
