In vitro genotoxicity of nitroimidazoles as a tool in the search of new trypanocidal agents

Memorias do Instituto Oswaldo Cruz
BACKGROUND Only benznidazole (Bnz) (1) and nifurtimox (Nfx) (2) are licensed for the treatment of Chagas disease although their safety and efficacy profile are far from ideal. Farmanguinhos from Fiocruz has developed seven nitroimidazole compounds (4-10)

Management of Periodontal Abscesses and Endodontic‐Periodontal Lesions—A Systematic Review

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate the management of periodontal abscesses and endodontic‐periodontal lesions (EPLs). Methods Seven focused questions addressed outcomes such as pocket depth (PD), bleeding on probing (BOP), tooth loss or ovoid elevation. The literature search covered three electronic databases and manual sources for intervention studies.
