Abstract: This study aimed to assess the cyclic fatigue resistance of Genius and EdgeFile X1 reciprocating instruments compared with WaveOne Gold Primary. Twenty Genius (Ultradent) 25.04, 20 Genius 30.04, 20 EdgeFile X1 (EdgeEndo) and 20 WaveOne Gold Primary (Dentsply Maillefer) instruments were included...

Adipokine gene variability and plasma levels in patients with chronic periodontitis -a case-control study

Abstract: Specific variants in genes that encode adipokines and their mRNA and protein expression were previously studied in type 2 diabetes mellitus (T2DM) and obesity, and similar studies have been performed for chronic periodontitis (CP). The aim of this case-control study was to investigate the possi...

Macrophages subpopulations in chronic periapical lesions according to clinical and morphological aspects

Abstract: The aim of this study was to evaluate macrophage M1 and M2 subpopulations in radicular cysts (RCs) and periapical granulomas (PGs) and relate them to clinical and morphological aspects. M1 macrophages were evaluated by the percentage of CD68 immunostaining associated with the inflammatory cytok...

Brittleness index and its relationship with materials mechanical properties: Influence on the machinability of CAD/CAM materials

Abstract: The aim of this study is to evaluate the machinability of four CAD/CAM materials (n = 13) assessed by brittleness index, Vickers hardness, and fracture toughness and interaction among such mechanical properties. The materials selected in this in vitro study are Feldspathic ceramic [FC], Lithium...

Effects of astragaloside IV on inflammation and immunity in rats with experimental periodontitis

Abstract: This study aimed to investigate the effects of astragaloside IV (AsIV) on inflammation and immunity in rats with experimental periodontitis. Periodontitis was established in 48 Wistar rats, which were then randomly divided into model and 10, 20 and 40 mg/kg AsIV groups, with 12 rats in each gro...

Immunohistochemical evaluation of HLA-G and FoxP3+ T regulatory cells in oral cavity and lower lip squamous cell carcinomas

Abstract: Human Leukocyte Antigen G (HLA-G) is a molecule involved in the tumor immunosuppression and also in the generation of regulatory T (Treg) cells, thus leading to evasion to the immune system host, and consequently, contributing to tumor progression in several cancers. The aim of this study was t...

Color stability and surface roughness of chitosan- and nanodiamond-modified bisacrylic resin

Abstract: The aim of this study is to evaluate the effect of chitosan or nanodiamond incorporation on the color stability and surface roughness of a bisacrylic resin subjected to artificial aging. Four bisacrylic resins were evaluated, namely, control, chitosan-modified material, nanodiamond-modified mat...

In vitro evaluation of Eugenia dysenterica in primary culture of human gingival fibroblast cells

Abstract: Eugenia dysenterica is a Brazilian tree investigated for its properties and bioactive compounds, which are believed to have both pharmacological and phytochemical therapeutic effects. The leaves of this tree contain tannins, flavonoids, terpenes, and saponins, with reportedly beneficial effects...
