Submucosal injection of dexamethasone or betamethasone for postoperative pain management in patients with symptomatic irreversible pulpitis: a randomized controlled clinical trial
Introduction: We evaluated the effect of apical submucosal infiltration of dexamethasone or betamethasone for postoperative pain management in symptomatic irreversible pulpitis. Methods:Ninety patients with symptomatic irreversible pulpitis in mandibular molars were randomly divided into three groups after single-visit endodontic treatment (n=30): control group (CG) received a sham injection, while dexamethasone (DG) and betamethasone (BG) groups received apical submucosal infiltration of 0.7 mL (4 mg/mL) dexamethasone or betamethasone.
