Differential effects of natural Curcumin and chemically modified curcumin on inflammation and bone resorption in model of experimental periodontitis
(2018-07-01)
Objective: The purpose of this study was to compare the effects of the oral administration of natural curcumin and a chemically modified curcumin (CMC2.24) on osteoclast-mediated bone resorption, apoptosis, and inflammation ...
Ovariectomy-associated changes in interradicular septum and in tibia metaphysis in different observation periods in rats
(Elsevier B.V., 2015-01-01)
In order to standardize an experimental model to study the effects of absence of ovarian hormones in maxillary bones compared with long bones, the aim of this research was to analyze the influence of ovariectomy (OVX) on ...
Characterization of ligature-induced experimental periodontitis
(2018-12-01)
We sought to better characterize the progression of periodontal tissue breakdown in rats induced by a ligature model of experimental periodontal disease (PD). A total of 60 male Sprague–Dawley rats were evenly divided into ...
Comparative study of volumetric changes and trabecular microarchitecture in human maxillary sinus bone augmentation with bioactive glass and autogenous bone graft: a prospective and randomized assessment
(2018-05-01)
The aim of this study was to compare the volumetric changes and the new bone microarchitecture in human maxillary sinuses augmented with bioactive glass (Biogran) alone, bioactive glass combined with autogenous bone graft ...
Severe magnesium deficiency compromises systemic bone mineral density and aggravates inflammatory bone resorption
(2020-03-01)
We sought to evaluate the effects of magnesium (Mg) intake deficiency on bone metabolism in rats with induced periodontal disease (PD). Holtzman rats were randomly divided into two groups: Control — animals fed a standard ...
Alveolar bone resorption and TH1/TH17-associated immune response triggered during Aggregatibacter actinomycetemcomitans-induced experimental periodontitis are serotype-dependent
(Wiley-Blackwell, 2018)
BACKGROUND:
Aggregatibacter actinomycetemcomitans expresses several virulence factors that may contribute to the pathogenesis of periodontitis. Based on the antigenicity of the O-polysaccharide component of the ...
IL-22–expressing CD4+AhR+ T lymphocytes are associated with RANKL-mediated alveolar bone resorption during experimental periodontitis
(Wiley, 2019)
BACKGROUND AND OBJECTIVE: Over the past few years, the importance of interleukin-22 (IL-22) and T-helper (Th)22 lymphocytes in the pathogenesis of periodontitis has become apparent; however, there are still aspects that ...
Unusual adenomatoid odontogenic tumor
(2016-03-23)
The adenomatoid odontogenic tumor is a rare benign neoplasm. It can, however, have locally aggressive behavior. This is a case of an adenomatoid odontogenic tumor of unusual location and behavior in a 15-year-old female ...
RANKL is a mediator of bone resorption in idiopathic hypercalciuria
(AMER SOC NEPHROLOGY, 2008)
Background and objectives: This study aimed to determine the expression of osteoprotegerin, receptor activator of nuclear factor kappa B ligand, interleukin-la, transforming growth factor-beta, and basic fibroblast growth ...
