[Research progress on the role of calcium ion transport in dental biomineralization].

Zhonghua Kou Qiang Yi Xue Za Zhi

January 2025

Department of Operative Dentistry and Endodontics, Shanghai Stomatological Hospital & School of Stomatology, Fudan University & Shanghai Key Laboratory of Craniomaxillofacial Development and Diseases, Fudan University, Shanghai201602, China.

Tooth development is a complex biomineralization process formed through the interaction between epithelial tissue and mesenchymal tissue. The Ca transport channel is the intrinsic regulatory mechanism of this process, which regulates the concentration of Ca inside and outside the cell in time and space, thereby affecting the biological functions of various cells and the growth of extracellular hydroxyapatite. This article reviews the researches on the effects of Ca transport in tooth biomineralization and corresponding cell development in recent years, with the aim of providing ideas and basis for the prevention of tooth developmental defects, assisting in early clinical diagnosis, and improving treatment methods.

Background: Based on the recommendation of the Ministry of Education in China to differentiate between "academic" and "professional" degrees, medical schools offer both professional and academic degrees for postgraduates. In China, clinical postgraduates who are pursuing a professional master's degree also participate in standardised residency training (SRT). However, little attention has been given to feedback from students and supervisors regarding postgraduate curricula.

Background: The multi-biological barriers present in the inflammatory microenvironment severely limit the targeted aggregation of anti-inflammatory drugs in the lesion area. However, conventional responsive drug carriers inevitably come into contact with several pro-responsive stimulatory mediators simultaneously, leading to premature drug release and loss of most therapeutic effects. Breaking through the multi-level barriers of the inflammatory microenvironment is essential to improve the enrichment and bioavailability of drugs.

RANKL and its receptor RANK play a vital role in osteoclastogenesis. RANK primarily recruits TRAFs to promote osteoclastogenesis but also contains an TRAF-independent motif (IVVY), which mediates osteoclast lineage commitment in vitro. Here, we have developed knockin mice in which inactivating mutations are introduced in the IVVY motif (IVVY to IVAF).

Article Synopsis
  • This study evaluated how different jaw movements and torque adjustments during mandibular advancement with clear aligners impact biomechanics using finite element analysis.
  • Models simulated the mandible, teeth, periodontal ligament (PDL), and clear aligners, incorporating forces from specific oral muscles during various jaw movements and torque compensation angles.
  • Results showed that maintaining a mandibular advancement distance close to the occlusal opening distance helped distribute stress evenly, while excessive opening increased stress and altered tooth positioning, highlighting the need for careful torque and movement control to ensure periodontal health.

Electrochemical biosensors hold great promise for the rapid screening of viral infectious diseases. However, the recognition elements of these biosensors are typically limited to antibodies, aptamers, and molecularly imprinted polymers. In this study, acetylated sialic acids were explored as recognition elements because they serve as natural viral receptors expressed on host cells.

Titanium and its alloys are the most commonly used biometals for developing orthopedic implants to treat various forms of bone fractures and defects, but their clinical performance is still challenged by the unfavorable mechanical and biological interactions at the implant-tissue interface, which substantially impede bone healing at the defects and reduce the quality of regenerated bones. Moreover, the impaired osteogenesis capacity of patients under certain pathological conditions such as diabetes and osteoporosis may further impair the osseointegration of Ti-based implants and increase the risk of treatment failure. To address these issues, various modification strategies have been developed to regulate the implant-bone interactions for improving bone growth and remodeling .

Tumor-colonized Streptococcus mutans metabolically reprograms tumor microenvironment and promotes oral squamous cell carcinoma.

Microbiome

October 2024

Hospital of Stomatology, Guanghua School of Stomatology, Sun Yat-Sen University, 56 Lingyuan Road West, Guangzhou, 510055, China.

Article Synopsis
  • Oral squamous cell carcinoma (OSCC) is a deadly form of head and neck cancer, with unclear mechanisms behind its development, but studies indicate that saliva from OSCC patients accelerates cancer progression in rat models.
  • Metabolomic analyses show that patients with OSCC have higher levels of kynurenic acid (KYNA) in their saliva and tumor tissues, which is correlated with the presence of Streptococcus mutans bacteria that contribute to KYNA production.
  • The increased KYNA promotes a tumor microenvironment that enhances immune suppression, leading to poorer outcomes in OSCC patients and suggesting that targeting oral microbiota may offer new prevention and treatment strategies for this type of cancer.
