Effect of Preoperative Oral Steroids in Comparison to Anti-inflammatory on Anesthetic Success of Inferior Alveolar Nerve Block in Mandibular Molars with Symptomatic Irreversible Pulpitis-A Double-blinded Randomized Clinical Trial.

Introduction: 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.

Methods: 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.

Inclusion Complexation of Etodolac with Hydroxypropyl-beta-cyclodextrin and Auxiliary Agents: Formulation Characterization and Molecular Modeling Studies.

The present investigation was aimed to prepare inclusion complexes of a therapeutically important nonsteroidal anti-inflammatory drug, etodolac (ETD) with hydroxypropyl-beta-cyclodextrin (HP-β-CD) and to study the effect of l-arginine (l-Arg) as an auxiliary agent on the complexation efficiency of HP-β-CD to improve aqueous solubility and the dissolution property of ETD. The binary and ternary complexes were prepared by physical mixing, coevaporation, and spray drying methods. The complexes were characterized using differential scanning colorimetry (DSC), Fourier transform-infrared spectroscopy (FT-IR), and powder X-ray diffraction (PXRD) studies.
