In vitro antibacterial activity of a silicone-based endodontic sealer and two conventional sealers

open access: yesBrazilian Oral Research, 2016
The aim of this study was to evaluate whether the modification in the silver component is capable of providing GuttaFlow 2 with antibacterial activity against Enterococcus faecalis compared with epoxy resin-based (AH Plus) and zinc oxide and eugenol ...

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

open access: yesMolecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Characterizing epithelial‐mesenchymal transition‐linked heterogeneity in breast cancer circulating tumor cells at a single‐cell level

open access: yesMolecular Oncology, EarlyView.
In over 50% of non‐metastatic breast cancer patients, circulating tumor cells (CTCs) along the whole epithelial‐mesenchymal transition spectrum are detected. Total CTC number and individual phenotypes relate to aggressive disease characteristics, including lymph node involvement and higher tumor proliferation. At the single‐cell level, mesenchymal CTCs

Antimicrobial Efficacy of Medicated Root Canal Filling Materials

open access: yesJournal of Endodontics, 2006
Bacteria remaining within the root canal system are a significant factor in endodontic failures. The aim of this in vitro study was to evaluate the antimicrobial efficacy of commercially available gutta-percha formulations against common endodontic pathogens. Standard, tetracycline, or iodoform (also called medicated gutta-percha; MGP) containing gutta-

3D In Vitro Models of Breast Cancer: Current Challenges and Future Prospects Toward Recapitulating the Microenvironment and Mimicking Key Processes

open access: yesAdvanced Biology, EarlyView.
In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.

Root filling bond strength using reciprocating file-matched single-cones with different sealers

open access: yesBrazilian Oral Research, 2016
The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers.

Clinical and radiographic evaluation of pulpectomies using three root canal filling materials: an in-vivo study.

open access: yesJournal of Indian Society of Pedodontics and Preventive Dentistry, 2010
Various root canal filling materials are used to preserve a pulpally involved carious primary tooth. But there is no single material so far available to fulfill all the requirements of an ideal root canal filling material for a primary tooth.
