Systemic Antibiotics in the Surgical Treatment of Peri‐Implantitis: Impact on the Salivary Microbiome

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To exploratorily compare the shifts in the salivary microbiome composition after administration of two combined systemic antibiotic regimens used in the surgical treatment of peri‐implantitis. Materials and Methods A subset of 27 patients treated surgically for peri‐implantitis with an adjunctive 7‐day course of systemic antibiotics were ...

Autogenous Demineralized Dentin Graft–Based Strategies With or Without I‐PRF and Metronidazole for Ridge Preservation in Infected Sockets: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This randomized controlled trial evaluated the efficacy of demineralized dentin graft (DDG) combined with injectable platelet‐rich fibrin (I‐PRF) and metronidazole (MTZ) versus DDG with or without I‐PRF in alveolar ridge preservation (ARP) of infected extraction sockets.

Preparation of 10B-enriched nitroimidazole derivative by click reaction as a functional drug for hypoxia-targeting boron-neutron capture therapy

Results in Chemistry
We report a novel drug that can be used for the treatment of tumor hypoxic cells by boron neutron capture therapy. We attempted to modify p‑boronophenylalanine, a agent for this therapy in practical use, with a hypoxia-accumulating functional group, 2 ...

Nitroimidazoles for imaging hypoxic myocardium

Journal of Nuclear Cardiology, 1995
A series of radiopharmaceuticals that incorporate nitroimidazole moieties have been synthesized to detect decreased local tissue pO2. In contrast to agents that localize in proportion to perfusion, these agents concentrate in hypoxic tissue. Myocardium with an intracellular pO2 < 3 mm Hg (about 25% of normal), which has lost its contractile ability but

Coupling of C-nitro-NH-azoles with arylboronic acids. A route to N-aryl-C-nitroazoles

Beilstein Journal of Organic Chemistry, 2013
A method for the synthesis of N-aryl-C-nitroazoles is presented. A coupling reaction between variously substituted arylboronic acids and 3(5)-nitro-1H-pyrazole catalyzed by copper salt has been carried out in methanol in the presence of sodium hydroxide ...

Some nitroimidazole derivatives as antibacterial and antifungal agents in in vitro study

Journal of Medical Science, 2019
Nitroimidazoles have wide range of therapeutic uses mainly as anaerobic antibacterials and antiprotozoal agents. Some bicyclic nitroimidazodihydrooxazoles and nitroimidazotetrahydrooxazines are found to be antituberculosis agents.

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...
