Preoperative steroids enhance anesthetic effect of inferior alveolar nerve block in mandibular molars with irreversible pulpitis
Preoperative steroids increase anesthetic effect of inferior alveolar nerve block in mandibular molars with irreversible pulpitis suggests a new study published in the Journal of Endodontics
This randomized double-blinded trial aimed to compare the anesthetic success of inferior alveolar nerve blocks (IANBs) with 2% lidocaine in mandibular molars with symptomatic irreversible pulpitis (SIP) after oral premedication of prednisolone, dexamethasone, and ketorolac with placebo.
One hundred eighty-four patients diagnosed with SIP in mandibular molars randomly received prednisolone, dexamethasone, ketorolac, or placebo (n = 46 each) 60 minutes before the administration of an IANB. The access cavity preparation was initiated after successfully confirming lip numbness and two consecutive negative responses to electric pulp testing. The success of the anesthesia was clinically confirmed when pain was absent during the endodontic access or instrumentation. A one-way analysis of variance test was used to compare quantitative variables among the groups, and chi-square tests were used for comparing categorical variables. Binary logistic regression was performed to analyze the relationship of age, preoperative pain, and preoperative medications.
Results
When premedicated with oral dexamethasone, ketorolac, prednisolone, and placebo, the success rate of IANB was determined to be 60.86 %, 65.21 %, 56.52 %, and 21.73 %, respectively. Compared to the placebo, the success rate of IANB was significantly increased when patients were premedicated with prednisolone, dexamethasone, or ketorolac. However, there were no statistically significant differences among prednisolone, dexamethasone, and ketorolac. One individual in the ketorolac group reported gastritis, whereas no adverse effects were reported in the dexamethasone or prednisolone groups.
Conclusions
Preoperative use of oral ketorolac, dexamethasone, or prednisolone may increase the anesthetic efficacy of IANB in mandibular molars with SIP.
