Drugs in oral surgery. Brief guidelines for adult patients.

Drugs administrable in oral surgery for adult patients are antiseptics-antibiotics, antiinflammatory-analgesics and sedative-hypnotics. Such drugs can be administered before, during or after oral surgery. Sedative-hypnotics can be administered before or during oral surgery in order to control the patient's anxiety. Anti-inflammatory-analgesics, on the other hand, can be administered before or after oral surgery to lower edema and pain. For this purpose, FANS are the most commonly used drugs but, in more traumatic oral surgery, the administration of a single pre-surgery dose of corticosteroids is suitable. As regards, antibiotics have to be given from 15 min to 1 h before oral surgery and continued or otherwise for 24-48 h depending on the dosage. post-surgery infection onset, in fact, is higher within 3 h after oral surgery.

Synthesis and binding mode of heterocyclic analogues of suramin inhibiting the human basic fibroblast growth factor.

The design, synthesis, and biological evaluation of a series of pyrrole and pyrazole congeners 2 of suramin, directed toward the development and identification of new ligands that complex the human fibroblast growth factor (bFGF), thereby inhibiting tumor-promoted angiogenesis, is reported. Compounds 2 were evaluated for their ability to inhibit binding of bFGF to its receptor, in vivo bFGF-induced angiogenesis, and neovascularization of the chorioallantoic membrane in comparison with suramin. These assays showed that ligands 2 exhibit moderate to good activity, comparable to that of suramin, and are less toxic than suramin itself. In this study, affinity data of ligands in combination with the crystal structure of bFGF were used to explain structure-affinity relationships and to gain an insight into the possible mode of ligand-protein interaction. Due to the lack of experimental structural data on the ligand-bFGF complexes, molecular mechanics techniques were used to obtain putative bioactive conformations and to generate docked complexes with the three-dimensional structure of bFGF. These experiments led to suggest that compounds 2 give rise to 1:1 complexes with bFGF through an unprecedented, bidentate attachment of their naphthylsulfonate groups to two main domains, commonly referred to as the heparin binding site and the receptor binding site, on bFGF, thus preventing the interaction of the growth factor with its receptor.

Implant surface and osseointegration.

Oral rehabilitation by means of osteointegrated implants is gaining more and more importance, in particular due to the improved characteristics of the fixture: among these, the superficial microscopical morphology plays a role of primary importance, since it can influence the evolution of the osteointegrative process. Therefore, this led to many surface treatments which can improve the quality and the speed of formation of the bony tissue. The aim of this paper is a review of the literature on this topic in order to find out which processes of characterization of the surface implant are now available and which results can be obtained.
