Attachment and growth of human osteoblasts on different biomaterial surfaces.

Objectives: To prove the biocompatibility of biomaterials applied in biomedical devices, in vitro testing is crucial to render a material fit for medical application. The material of choice for dental implants is commercially pure titanium (cp-Ti), while other materials such as zirconia and polyetheretherketone (PEEK) are considered highly promising due to their functional and esthetic properties. The aim of this study was to determine whether PEEK with defined mean surface roughness and composition could achieve results equal to titanium or zirconia.

Beneficial effect of methylprednisolone after mandibular third molar surgery: a randomized, double-blind, placebo-controlled split-mouth trial.

Objectives: Third molar (M3) removal is the model most frequently used for pain trials in oral surgery. Corticosteroids are frequently administered to reduce trismus and swelling after dentoalveolar surgical procedures. The purpose of this investigation was to evaluate the influence of a single, preoperative oral application of methylprednisolone on postoperative trismus, pain intensity, and the subjective need for analgesic medication after surgical removal of impacted mandibular M3 (LM3).
