Objective: To evaluate the effect of the toothpaste containing ε-poly-L-lysine (ε-PL) and funme peptide (FP) as key components on oral microbial composition and oral health.

Methods: An oral microbiome study was initially carried out to analyze the variation in the oral microbiota before and after use of antimicrobial peptide (AMP) toothpaste. Subsequently, a clinical trial was independently performed to assess the efficacy of AMP toothpaste by measuring the dental plaque index (PLI), volatile sulfur compounds (VSCs) levels, modified bleeding index (mBI), and bleeding on probing rate (BOP%).

Photothermal Coating on Zinc Alloy for Controlled Biodegradation and Improved Osseointegration.

Adv Sci (Weinh)

January 2025

Department of Prosthodontics, Peking University School and Hospital of Stomatology, No.22, Zhongguancun South Avenue, Haidian District, Beijing, 100081, China.

Zinc (Zn) and its alloys are promising biomaterials for orthopedic applications due to their degradability and mechanical properties. Zn plays a crucial role in bone formation, but excessive early release may cause cytotoxicity and inhibit osseointegration. To solve this, we developed a near-infrared (NIR) light-controlled polycaprolactone/copper-sulfur (PCL/CuS) coating that slows degradation and enhances osseointegration of Zn alloys.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease which afflicts about nearly 1% of global population. RA results in synovitis and cartilage/bone damage, even disability which aggravates the health burden. Many drugs are used to relieve RA, such as glucocorticoids (GCs), non-steroidal anti-inflammatory drugs (NSAIDs), and disease-modifying anti-rheumatic drugs (DMARDs) in the clinical treatment.

Background: Fibrous dysplasia (FD), caused by activating mutations of GNAS, is a skeletal disorder with considerable clinicopathological heterogeneity. Although prevalent mutations such as R201C and R201H dominate in FD, a limited number of rare mutations, including R201S, R201G, and Q227L, have been documented. The scarcity of information concerning these uncommon mutations motivates our investigation, seeking to enhance comprehension of this less-explored subgroup within FD.

Article Synopsis
  • Oral mucosal wounds are susceptible to inflammation and complications due to exposure to microorganisms, which can hinder daily activities and diminish quality of life.
  • A novel therapeutic nanoplatform, DATS@Arg-EA-SA, has been developed to target these wounds by combining guanidinated dendritic peptides with diallyl trisulfide (DATS), providing both antimicrobial and anti-inflammatory effects.
  • This nanoplatform effectively eliminates various bacteria, including drug-resistant strains like MRSA, and enhances healing by promoting the transition of inflammatory cells and alleviating pain, making it a promising solution for oral wound treatment.
