1. Synergic effect of simvastatin in combination with amphotericin B against environmental strains of Cryptococcus neoformans from northeastern Brazil: a prospective experimental study
BACKGROUND: Statins are used as cholesterol-lowering drugs and may also have direct antimicrobial effects. OBJECTIVE: To evaluate synergic interactions between simvastatin and both amphotericin B and fluconazole, against environmental strains of Cryptococcus neoformans isolated from captive birds’ droppings. DESIGNAND SETTING: Experimental study cond

2. Effect of passive ultrasonic activation on microorganisms in primary root canal infection: a randomized clinical trial
Abstract Objective: This clinical study sought to evaluate the effectiveness of passive ultrasonic activation (PUA) in eliminating microorganisms in primary endodontic infection (PEI) after instrumentation of root canals using microbiological culture and checkerboard DNA-DNA hybridization. Methodology: Twenty root canals with PEI and apical periodontitis w

3. Microbial profile of symptomatic pericoronitis lesions: a cross-sectional study
Abstract Objective: The microbial composition of pericoronitis (Pc) is still controversial; it is not yet clear if the microbial profile of these lesions is similar to the profile observed in periodontitis (Pd). Therefore, the aim of the present study was to describe the microbial profile of Pc lesions and compare it directly with that of subjects with Pd.

4. Microbial Profile and Endotoxin Levels in Primary Periodontal Lesions with Secondary Endodontic Involvement
Resumo Este estudo foi realizado para investigar o perfil microbiano e os níveis de endotoxina de lesões endoperiodontais de origem periodontal. Amostras periodontais e endodônticas foram obtidas de bolsas periodontais e canais radiculares necróticos de 10 dentes com lesões endoperiodontais. A investigação de 40 espécies bacterianas diferentes foram

5. Plant Extracts Display Synergism with Different Classes of Antibiotics
Abstract: One manner in which plant-derived compounds exert their antibiotic potential is the synergism, a positive interaction between two compounds. Studies indicate that the use of plant extracts combined with antimicrobials may promote a significant reduction of the minimum inhibitory concentrations of antibiotics for bacterial strains. This study aimed

6. Microbial species associated with dental caries found in saliva and in situ after use of self-ligating and conventional brackets
Abstract Objectives Enamel demineralization is among the main topics of interest in the orthodontic field. Self-ligating brackets have been regarded as advantageous in this aspect. The aim of this study was to evaluate the break homeostasis in the oral environment and the levels of microorganisms associated with dental caries among the different types of b

7. Correlation Between Volume of Root Canal, Cultivable Bacteria, Bacterial Complexes and Endotoxins in Primary Infection
Resumo Este estudo clínico foi conduzido para correlacionar os níveis de endotoxinas e bactérias cultiváveis encontradas na infecção endodôntica primária (IEP) com o volume do canal radicular determinado pelo uso da Tomografia Computadorizada de Feixe Cônico (TCFC); e avaliar a diversidade bacteriana correlacionada com características clínicas.

8. Interaction study between vancomycin and liposomes containing natural compounds against methicillin-resistant Staphylococcus aureus clinical isolates
ABSTRACT The treatment of infections caused by resistant microorganisms is limited, and vancomycin (VAN) treatment failures for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia are not uncommon, even when MRSA clinical isolates are susceptible to VAN. Thus, this study proposed the association of VAN with usnic acid and β-lapachone encapsulated

9. Successful and failed mini-implants: microbiological evaluation and quantification of bacterial endotoxin
Abstract Objectives Using two groups of mini-implants (successful and failed) the objectives of this in vivo study were: to evaluate the microbial contamination by the checkerboard DNA-DNA hybridization technique and to quantify the bacterial endotoxin by the limulus amebocyte lysate assay. Material and Methods The 15 successful and 10 failed mini-implan

10. Avaliação das espécies Enterococcus faecalis, Staphylococcus warneri e Staphylococcus aureus em adultos com periodontite crônica generalizada
RESUMO Objetivo: Identificar e quantificar os níveis de três espécies bacterianas que foram recentemente apontadas como possíveis “novos” patógenos periodontais (Enterococcus faecalis, Staphylococcus warneri e Staphylococcus aureus), em indivíduos periodontalmente saudáveis e com periodontite crônica generalizada. Métodos: A amostra foi compos

11. Clinical trial for evaluation of Ricinus communis and sodium hypochlorite as denture cleanser
Abstract The development of opportunistic infections due to poor denture hygiene conditions justified the search for effective hygiene protocols for controlling denture biofilm. Objective This study evaluated Ricinus communis and sodium hypochlorite solutions in terms of biofilm removal ability, remission of candidiasis, antimicrobial activity, and partici

12. Effectiveness of a pre-procedural mouthwash in reducing bacteria in dental aerosols: randomized clinical trial
Abstract The aim of this randomized, single blinded clinical trial was to evaluate the effect of a pre-procedural mouthwash containing cetylpyridinium chloride (CPC), zinc lactate (Zn) and sodium fluoride (F) in the reduction of viable bacteria in oral aerosol after a dental prophylaxis with ultrasonic scaler. Sixty systemically healthy volunteers receiving
