Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Effect of antibiotics against Mycoplasma sp. on human embryonic stem cells undifferentiated status, pluripotency, cell viability and growth [PDF]

open access: yes, 2013
Human embryonic stem cells (hESCs) are self-renewing pluripotent cells that can differentiate into specialized cells and hold great promise as models for human development and disease studies, cell-replacement therapies, drug discovery and in vitro ...

Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.

Docking studies on novel analogs of quinolones against DNA gyrase of Escherichia coli [PDF]

open access: yesJournal of Pharmacy & Pharmacognosy Research, 2018
Context: Bacterial resistance to antibiotics is the inevitable consequence of the use of antimicrobial agents. Thus, quinolones are an important class of antibacterials; these agents generally consist of a 1-subtituted-1,4-dihydro-4-oxopyridine-3 ...

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Safety of sulfamethoxazole–trimethoprim for the treatment of bacterial infection in outpatient settings: A systematic review and meta‐analysis with active comparator disproportionality analysis

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Sulfamethoxazole–trimethoprim (SMX‐TMP) is a widely used antibiotic for treating bacterial infections, but its safety in adult outpatients remains understudied. This systematic review and meta‐analysis evaluated the safety profile of SMX‐TMP and identified critical research gaps.
