The aim of this study was to determine the therapeutic effects of mineral trioxide aggregate (MTA) and methyl sulfonyl methane (MSM) on pulp damage due to pulp exposure through the RUNX2 and RANKL pathways. Seventy-two male Sprague-Dawley rats aged 4-6 months and weighing 250-300 g were divided into healthy, control, MTA, and MSM groups. After experimental applications, all rats at 2, 4, and 8 weeks were killed anesthetically with xylazine hydrochloride (Rompun, Bayer) 30 mg/kg and ketamine hydrochloride (Ketalar, Pfizer) 50 mg/kg injections (i.p.). We observed that necrotic odontoblasts, edema, inflammation, and vascular congestion findings were reduced from week 2 to week 8 in the MSM treatment group after pulp capping compared to the control group and MTA group. Similarly, we found a decrease in RUNX2 and RANKL levels in the MSM application group compared to the control and MTA groups (p < 0.05). MSM material has shown therapeutic effects on pulp capping treatment-induced pulp injury via increased RUNX2 ve RANKL expression.

In recent years, polysaccharides derived from natural sources have garnered significant attention due to their safety and potential anti-osteoporotic effects. This review provides a comprehensive overview of the sources, distribution, structures, and mechanisms of anti-osteoporosis polysaccharides, as well as an investigation into their structure-activity relationships. Over thirty distinct, homogenous polysaccharides with anti-osteoporosis properties have been extracted from natural sources, primarily categorized as glucans, fructans, galactomannans, glucomannans, and various other heteropolysaccharides.

It was assumed that only autogenous bone had appropriate osteoconductive and osteoindutive properties for bone regeneration, but this assumption has been challenged. Many studies have shown that synthetic biomaterials must be considered as the best choice for guided bone regeneration. The objective of this work is to compare the performances of nanohydroxyapatite/β-tricalcium phosphate (n-HA/β-TCP) composite and autogenous bone grafting in bone regeneration applications.

Type 2 diabetes and weight loss are associated with detrimental skeletal health. Incretin-based therapies (GLP-1 receptor agonists, and dual GIP/GLP-1 receptor agonists) are used clinically to treat diabetes and obesity. The potential effects of semaglutide and tirzepatide on bone metabolism in type 2 diabetic mice remain uncertain.

ATP-dependent chromatin remodeling protein ATRX is an essential regulator involved in maintenance of DNA structure and chromatin state and regulation of gene expression during development. ATRX was originally identified as the monogenic cause of X-linked α-thalassemia mental retardation (ATR-X) syndrome. Affected individuals display a variety of developmental abnormalities and skeletal deformities.

Background: The rapid decline in ovarian function associated with menopause promotes osteoclast differentiation and increases bone resorption, disrupting of bone homeostasis and increasing the risk of osteoporosis. Hyaluronic acid (HA) is a polysaccharide ubiquitously present in the connective tissues. Recent reports indicate that high-molecular-weight HA (HMW-HA) promotes osteoblast proliferation, enhances alkaline phosphatase activity and mineral deposition, and promotes the expression of bone differentiation markers, such as Runx2 and osteocalcin.
