1. Antibacterial Effects of Cuminum cyminum Extract Against Enterococcus Faecalis Biofilms From Clinical Isolates
Abstract Objective: To compare the antibacterial efficacy of Cuminum cyminum (cumin) extract and 2% chlorhexidine. Material and Methods: E. faecalis was isolated from non-vital teeth with chronic apical abscess. Samples were then bred in the ChromAgar medium. Subsequently, E. faecalis bacteria’s DNA extraction was performed. DNA was then amplified by con

2. 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. 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

5. 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

6. The effects of different restorative materials on periodontopathogens in combined restorative-periodontal treatment
Abstract Objective The aim of the study was to evaluate the association between subgingival restorations and the target periodontopathogenic bacteria (Pg, Td and Pi) in subgingival biofilm during one year after combined restorative-periodontal treatment. Material and Methods Seventeen systemically healthy subjects, who were positive for the presence of t

7. Predictors of clinical outcomes after periodontal treatment of aggressive periodontitis: 12-month randomized trial
Abstract Little is known about the factors that may be used in clinical practice to predict the therapeutic response of aggressive periodontitis patients. The aim of this study was to determine predictors of clinical outcomes after non-surgical treatment of aggressive periodontitis. A total of 24 patients (aged 13-26 years) received oral hygiene instructions

8. Expression analysis of Notch signaling pathway molecules in SHED cultured in keratinocyte growth medium
Aim: To detect the expression of molecules associated with Notch signaling pathway in stem cells from human exfoliated deciduous teeth (SHED) cultured in specific differentiation medium, namely, keratinocyte growth medium (KGM).
Methods: RNA was extracted from SHED harvested on day 1, 3 and 7. RNA was reve

9. Prevalence of Treponemaspp. in endodontic retreatment-resistant periapical lesions
This study investigated the presence of the Treponema species in longstanding endodontic retreatment-resistant lesions of teeth with apical periodontitis, the association of this species with clinical/radiographic features, and the association among the different target species. Microbial samples of apical lesions were collected from twenty-five adult patien

10. The use of a DNA stabilizer in human dental tissues stored under different temperature conditions and time intervals
Objective: The present study evaluated the use of a reagent to stabilize the DNA extracted from human dental tissues stored under different temperature conditions and time intervals. Material and Methods: A total of 161 teeth were divided into two distinct groups: intact teeth and isolated dental pulp tissue. The samples were stored with or without the pr

11. Microbial Reduction by Two Chemical-Mechanical Protocols in Primary Teeth with Pulp Necrosis and Periradicular Lesion - An In Vivo Study
O objetivo deste estudo foi determinar a eficácia das manobras químico-mecânicas de dois protocolos endodônticos, na redução do conteúdo séptico de canais radiculares de dentes decíduos com polpa necrosada e lesão perirradicular. Vinte e quatro canais radiculares decíduos com necrose pulpar e lesão perirradicular foram divididos em dois grupos de

12. Increased levels of Porphyromonas gingivalis are associated with ischemic and hemorrhagic cerebrovascular disease in humans: an in vivo study
OBJECTIVE: This study investigated the role of periodontal disease in the development of stroke or cerebral infarction in patients by evaluating the clinical periodontal conditions and the subgingival levels of periodontopathogens. MATERIAL AND METHODS: Twenty patients with ischemic (I-CVA) or hemorrhagic (H-CVA) cerebrovascular episodes (test group) and 60
