1. Influence of genetic regulatory effects modified by environmental immune activation on periapical disease
Abstract: The objective of this study was to compare the periradicular responses in endodontic infections among members of two populations: an urban Brazilian population and a non-mixed indigenous population. Samples were collected immediately and 7 days after the cleaning and shaping procedures (after reducing the intracanal microbial load) in an attempt to

2. Comparison of rRNA-based reverse transcription PCR and rDNA-based PCR for the detection of streptococci in root canal infections
Abstract Objective The rDNA-based method is unable to distinguish between alive and dead cells. Alternatively, bacterial viability can be assessed by molecular methods based on ribosomal RNA (rRNA). Therefore, this study aimed to detect viable streptococci in root canal samples using rRNA-based reverse transcription polymerase chain reaction (RT-PCR), comp

3. Comparison of two rotary systems in bacteria/lps removal from endodontic infections: randomized clinical trial
Abstract: This clinical study compared the effectiveness of two rotary systems: HyFlex CM (Coltene-Whaledent, Altstetten, Switzerland) and ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland) on the removal of cultivable bacteria and endotoxins from primarily infected root canals. This study was designed as a randomized single-blinded, 2-arm, clinical tr

4. Endodontic medicine: interrelationships among apical periodontitis, systemic disorders, and tissue responses of dental materials
Abstract: Endodontic medicine, which addresses the bidirectional relationship between endodontic infections and systemic diseases, has gained prominence in the field of endodontics. There is much evidence showing that while systemic disease may influence the pathogenesis of endodontic infection, endodontic infection can also cause systemic alterations. These

5. Etiologic role of root canal infection in apical periodontitis and its relationship with clinical symptomatology
Abstract: Evidence shows the polymicrobial etiology of endodontic infections, in which bacteria and their products are the main agents for the development, progression, and dissemination of apical periodontitis. Microbial factors in necrotic root canals (e.g., endotoxin) may spread into apical tissue, evoking and supporting a chronic inflammatory load. Thus,

6. Culture-dependent approaches to explore the prevalence of root canal pathogens from endodontic infections
Abstract: Endodontic infections are considered to be caused by the presence of various microorganisms within the root canal system. Recognition of this microbiota contributes to the successful treatment of infected root canals. This study investigated the microorganisms associated with primary and secondary endodontic infections via culture methods, biochemi

7. 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

8. Sickle cell anemia in Brazil: personal, medical and endodontic patterns
Abstract Sickle cell anemia (SCA) is the most prevalent genetic disease worldwide. Recurrent vaso-occlusive infarcts predispose SCA patients to infections, which are the primary causes of morbidly and mortality. This study aimed to evaluate the relationship between SCA and endodontic diseases. Personal information, medical data (hematological indices, virolo

9. A new improved protocol for in vitro intratubular dentinal bacterial contamination for antimicrobial endodontic tests: standardization and validation by confocal laser scanning microscopy
Objectives To compare three methods of intratubular contamination that simulate endodontic infections using confocal laser scanning microscopy (CLSM). Material and Methods Two pre-existing models of dentinal contamination were used to induce intratubular infection (groups A and B). These methods were modified in an attempt to improve the model (group C).

10. Saliva, supragingival biofilm and root canals can harbor gene associated with resistance to lactamic agents
This study aimed to determine the presence of Prevotella strains and genes associated with resistance to lactamics in different oral niches from patients with/without primary endodontic infections. Saliva (S) and supragingival biofilm (SB) were collected from three patient groups: Group I – no endodontic infection (n = 15); Group II – acute endodontic in

11. 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

12. An investigation of the presence of specific anaerobic species in necrotic primary teeth
Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs) and root canals (RCs) of infected primary teeth using PCR methods. Paired PC and RC samples were collecte
