Effect of pretreatment medication on postendodontic pain: A double-blind, placebo-controlled study.

Background: Posttreatment endodontic pain has been reported in 25%-40% of all endodontic patients. Effective management of endodontic pain represents a continuing challenge.

Aim: To evaluate and compare the efficacy of preoperative single dose of nonsteroidal anti-inflammatory drug, piroxicam (20 mg), with two types of corticosteroid drugs - dexamethasone (4 mg) or deflazacort (30 mg) - for the prevention and control of postendodontic pain.

Comparative evaluation of fracture resistance of root dentin to resin sealers and a MTA sealer: An in vitro study.

Background: Endodontic obturating materials should form monoblocks, reinforcing the treated teeth against fracture.

Aim: To evaluate and compare the effect of two resin sealers and a MTA sealer on the fracture resistance of endodontically treated teeth.

Materials And Methods: Fifty single-rooted mandibular premolars, decoronated at cemento-enamel junction, were divided into 5 groups (n = 10 each).
