RESUMO

Posttreatment endodontic pain is still a significant problem in dentistry. The aim of this randomized double-blind study was to evaluate, in two stages, the effect of betamethasone on the control of postoperative pain in patients submitted to endodontic treatment. In the first stage, patients were asymptomatic, whereas in the second, pain was already present before the treatment. Volunteers (n=102), both genders, were submucosally injected with a single dose of a betamethasone solution (0.05 mg/body weight) or a sterile saline solution (placebo) after endodontic treatment completion. All volunteers received a vestibular injection periapically to the tooth treated. To assess pain intensity, verbal descriptive scales were given to all volunteers. Answers were given from their homes by telephone at 4, 24, and 48 hours afier endodontic treatment. The Chi-square, Mann-Whitney and Fischer s exact tests were used for statistical analysis. In the first stage, pain intensity was significantly lower for patients treated with betamethasone in the three periods tested (4 hours: p=0.0007;24 hours: p=0.0022; 48 hours: p=0.0126), when compared to placebo. In the second stage, pain was also better controlled by betamethasone at periods of 4 hours (p=0.0177) and 24 hours (p=0.0012) for patients treated with betamethasone, when compared to placebo. In conclusion, once the pain caused by endodontic instrumentation is in general more intense at the first 24 hours after treatment, betamethasone might be used as an adjuvant therapy to pain control in endodontic procedures
