Comparison of Postoperative Pain Management after Third Molar Extraction with Two Anti-Inflammatory Drugs.

Background: The present study was aimed to investigate the pre-emptive analgesia attained with oral celecoxib compared with oral acetaminophen post mandibular third molar surgery.

Methodology: A double-blinded, randomized, placebo-controlled clinical trial was performed in order to examine patients having a mandibular third molar for extraction under local anesthesia. The patients were randomized for receiving a preoperative oral dosage of celecoxib or acetaminophen as the predictor parameter.

Effect of four different surface treatments on shear bond strength of three porcelain repair systems: An in vitro study.

Background: Ceramic fracture in metal ceramic restorations are serious and pose an aesthetic and functional dilemma both for the patients and the dentist. This has created a demand for the development of practical repair options which do not necessitate the removal and remake of entire restorations.

Aim: To evaluate and compare the effect of four different surface treatments on shear bond strength of metal ceramic specimens with three commercially available porcelain repair systems.
