Efeito de cimentos endodônticos na dor pós-operatória: ensaio clínico randomizado

Abstract

There are several endodontic sealers available for clinical use, however little is known about the influence of these materials may have on pos operative pain. Thus, the main of this study was to compare was to compare the occurrence and intensity of postoperative pain using AH Plus, MTA Fillapex and EndoFill as endodontic sealers through a randomized clinical trial. Sixty patients with a need for endodontic treatment with a diagnosis of pulp necrosis were selected, divided into three groups (n = 20) according to the endodontic sealer used: AH Plus; MTA Fillapex; EndoFill. All teeth were instrumented with WaveOne Gold system and irrigation was performed with 2.5% sodium hypochlorite. After using intracanal dressing with calcium hydroxide, the root canal filling was performed with gutta-percha and endodontic sealer. The postoperative pain evaluation was performed after 24h, 48h and 7 days using a numerical scale (0 to 10), 0 being "no pain", 5 equivalent to "moderate pain" and 10 being "worse pain possible ". The intensity of the pain was considered as follows: 0 - no pain; 1 to 4 - mild pain; 5 to 8 - moderate pain, 9 and 10 - severe pain. The need for analgesic intake was also observed. No difference between the groups was detected in the incidence and intensity of postoperative pain or the need for analgesics during the periods observed. We also found no association between patient and tooth factors included in a regression analysis (p> 0.05). It can be concluded that Ah Plus, MTA Fillapex and EndoFill present similar results in the occurrence and intensity of postoperative pain after endodontic treatment.
