Bone regeneration following trauma, tumor resection, infection, or congenital disease is challenging. Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia. It can result in complications affecting multiple systems including the musculoskeletal system. The increased number of diabetes-related fractures poses a great challenge to clinical specialties, particularly orthopedics and dentistry. Various pathological factors underlying DM may directly impair the process of bone regeneration, leading to delayed or even non-union of fractures. This review summarizes the mechanisms by which DM hampers bone regeneration, including immune abnormalities, inflammation, reactive oxygen species (ROS) accumulation, vascular system damage, insulin/insulin-like growth factor (IGF) deficiency, hyperglycemia, and the production of advanced glycation end products (AGEs). Based on published data, it also summarizes bone repair strategies in diabetic conditions, which include immune regulation, inhibition of inflammation, reduction of oxidative stress, promotion of angiogenesis, restoration of stem cell mobilization, and promotion of osteogenic differentiation, in addition to the challenges and future prospects of such approaches.

Oscillatory fluid flow enhanced mineralization of human dental pulp cells.

Department of Preventive Dentistry, Division of Pediatric Dentistry, Faculty of Dentistry, Naresuan University, Phitsanulok, Thailand.

The purpose of this study is to evaluate the optimum frequency of oscillatory fluid flow (OFF) for increasing osteogenesis in human dental pulp cells (DPCs) in an incubating rocking shaker. DPCs from 3 donors were cultured in an osteogenic induction medium (OIM) and mechanical stimulation was applied using an incubating rocking shaker at frequencies of 0 (control), 10, 20, 30, and 40 round per minute (RPM) for 1 h/day, 5 days/week. Cell proliferation was measured using total protein quantification, and osteogenic activity was measured by alkaline phosphatase (ALP) activity, calcium deposition, and collagen production on days 7, 14, and 21 of culture.

Bone remodeling, a continuous process of resorption and formation, is essential for maintaining skeletal integrity and mineral balance. However, in cases of critical bone defects where the natural bone remodeling capacity is insufficient, medical intervention is necessary. Traditional bone grafts have limitations such as donor site morbidity and availability, driving the search for bioengineered scaffold alternatives.

Cartilage repair remains a significant challenge due to the tissue's limited innate regenerative capacity. Despite advances in techniques such as microfracture, autologous chondrocyte implantation (ACI), and osteochondral grafting, long-term outcomes are often compromised by complications, including suboptimal tissue integration, graft resorption, and mechanical instability. Recently, biologically augmented scaffold-based cartilage repair has emerged as a promising approach for full-thickness osteochondral lesions.

Chirality is one of the basic characteristics of living matter, yet the effect of chiral polymers on osteogenesis is seldom studied. Thus, it is necessary to deeply recognize the behaviors of chiral polymers in osteogenic processes, which can be beneficial for the development of bone repair materials. In this work, chiral hydroxyapatite (HAP) was constructed simply using poly(levorotatory/dextral-tartaric acid) as the guest of the chiral transfer system.

In modern dentistry, prosthetic approaches such as implants and dentures have been developed as symptomatic solutions for tooth loss. However, the complete regeneration of teeth and periodontal tissue, an ultimate aspiration of humanity, remains unachieved. Recent advancements in fundamental scientific technologies, including single-cell RNA sequencing and spatial transcriptomics, have significantly advanced our molecular understanding of tooth development, paving the way toward achieving this goal.
