25. Antibacterial activity of (-)-cubebin isolated from Piper cubeba and its semisynthetic derivatives against microorganisms that cause endodontic infections
Abstract Recent publications have highlighted the numerous biological activities attributed to the lignan (-)-cubebin (1), Piper cubeba L. f., Piperaceae, and ongoing studies have focused on its structural optimization, in order to obtain derivatives with greater pharmacological potential. The aim of this study was the obtainment of (1), its semisynthetic de

26. Frequency of periodontal pathogens and Helicobacter pylori in the mouths and stomachs of obese individuals submitted to bariatric surgery: a cross-sectional study
ABSTRACT Objectives This cross-sectional study compared the frequency of oral periodontopathogens and H. pylori in the mouths and stomachs of obese individuals with or without periodontitis submitted to bariatric surgery. Material and Methods One hundred and fifty-four men and women aged 18-65 were conveniently distributed into four groups. Two groups we

27. Comparison of Fusobacterium nucleatum and Porphyromonas gingivalis Lipopolysaccharides Clinically Isolated from Root Canal Infection in the Induction of Pro-Inflammatory Cytokines Secretion
Resumo O objetivo deste estudo foi comparar a atividade biológica de lipopolissacarídeos (LPS) purificados a partir de linhagens de Fusobacterium nucleatum e Porphyromonas gingivalis, ambas isoladas de infecções endodônticas primárias (IEP) nos níveis de IL-1β e TNF-α produzidos por macrófagos. Adicionalmente, LPS foi purificado de F. nucleatum e P

28. Lactobacillus rhamnosus could inhibit Porphyromonas gingivalis derived CXCL8 attenuation
ABSTRACT An increasing body of evidence suggests that the use of probiotic bacteria is a promising intervention approach for the treatment of inflammatory diseases with a polymicrobial etiology. P. gingivalis has been noted to have a different way of interacting with the innate immune response of the host compared to other pathogenic bacteria, which is a rec

29. Presença de espécies de Porphyromonas e Prevotella na microbiota oral de bovinos com periodontite
Resumo: A periodontite bovina é um processo infeccioso purulento e progressivo associado à presença de biofilme subgengival anaeróbio estrito e facultativo e de incidência em extensas áreas geográficas do Brasil. O trabalho teve por objetivo detectar espécies dos gêneros Porphyromonas e Prevotella presentes na bolsa periodontal de bovinos com lesõe

30. Host response mechanisms in periodontal diseases
Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia and Treponema denticola that trigger innate, inflammatory, and adaptive immune respon

31. Antimicrobial and cytotoxic effects of phosphoric acid solution compared to other root canal irrigants
Phosphoric acid has been suggested as an irrigant due to its effectiveness in removing the smear layer. Objectives : The purpose of this study was to compare the antimicrobial and cytotoxic effects of a 37% phosphoric acid solution to other irrigants commonly used in endodontics. Material and Methods : The substances 37% phosphoric acid, 17% EDTA, 10% citric

32. Association between periodontal condition and subgingival microbiota in women during pregnancy: a longitudinal study
Objectivo In this study, the gingival conditions and the quantitative detection for Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis and Prevotella intermedia in pregnant women were determined. Material and Methods Quantitative determinations of periodontal bacteria by using a SyBr green system in women during pre

33. Effects of stress hormones on the production of volatile sulfur compounds by periodontopathogenic bacteria
Little is known about the effects of stress hormones on the etiologic agents of halitosis. Thus, the aim of this study was to evaluate in vitro the effects of adrenaline (ADR), noradrenaline (NA) and cortisol (CORT) on bacteria that produce volatile sulfur compounds (VSC), the major gases responsible for bad breath. Cultures of Fusobacterium nucleatum (Fn),

34. Bacteriological analysis of necrotic pulp and fistulae in primary teeth
Objectives: Primary teeth work as guides for the eruption of permanent dentition, contribute for the development of the jaws, chewing process, preparing food for digestion, and nutrient assimilation. Treatment of pulp necrosis in primary teeth is complex due to anatomical and physiological characteristics and high number of bacterial species present in end

36. Avaliação clínica e microbiológica do protocolo one-stage full-mouth disinfection: estudo de curto prazo
RESUMO INTRODUÇÃO: Os pacientes parecem aderir melhor ao tratamento periodontal de curto prazo. Além disso, tratamentos de tempo curto possuem melhor custo-benefício. No entanto, os benefícios associados a este tipo de tratamento ainda requerem investigações adicionais. OBJETIVO: O presente estudo avaliou longitudinalmente indivíduos com periodontite
