Efeito dos cimentos à base de silicato de cálcio e resina epóxica na dor pós-operatória em endodontia: ensaio clínico randomizado

Abstract

This double-blind randomized clinical trial evaluated the occurrence of postoperative pain by comparing two root canal filling material protocols, one using calcium silicate-based sealer and the other using epoxy resin-based sealer, after endodontic treatment. Seventy teeth from adult patients were selected, with 36 teeth obturated using calcium silicate-based sealer and 34 with resin-based sealer. Endodontic treatment was performed using the reciprocating system WaveOne Gold®. During the root canal filling stage, patients were randomized into one of the groups, and the obturation technique employed was thermocompaction. Postoperative pain assessment was conducted at intervals of 6, 12, 24, 48, and 72 hours after endodontic treatment, using the Numeric Rating Scale (NRS 0-10). The results demonstrated that there was no statistically significant difference in the occurrence of pain between the groups during the studied periods: 6h (p=0.632), 12h (p=0.673), 24h (p=0.318), 48h (p=0.913), and 72h (p=0.736). Regression analysis revealed a 4.5-fold increase in the risk of postoperative pain in the presence of extrusion of root canal filling material (RR=4.55 [1.25-16.62]), independent of study groups and other variables in the model. However, older individuals reported less pain at 24 hours (RR=0.92 [0.89-0.97]). In conclusion, there was no difference in the occurrence and intensity of pain between the studied groups.
