Area of Science:

  • Oral microbiology
  • Biomaterials science
  • Immunohistochemistry

Background:

  • Fibronectin is known to bind to oral bacteria and various biological components.
  • Fibronectin is present in salivary flow, acquired pellicle, and dental plaque.
  • Dental prosthetics, such as acrylic resin dentures, can accumulate oral bacteria and biofilms.

Purpose of the Study:

  • To investigate the presence and location of fibronectin on used acrylic resin dentures.
  • To understand the interaction between fibronectin and denture surfaces.
  • To explore potential implications for oral hygiene and denture colonization.

Main Methods:

  • Direct immunohistochemical fluorescent technique was employed.
  • Antihuman fibronectin goat serum labeled with fluorescein isothiocyanate (FITC) was used for detection.

  • Samples were obtained from used acrylic resin dentures.

    • Main Results:

    • Fibronectin was frequently detected on the surface of acrylic resin dentures.
    • The findings indicate fibronectin's affinity for denture materials.
    • Immunohistochemical analysis confirmed fibronectin's presence in this environment.

    Conclusions:

    • Fibronectin is a common component found on the surface of used acrylic resin dentures.
    • This presence may influence bacterial adhesion and biofilm formation on dentures.
    • Further research is warranted to explore the clinical significance of fibronectin on denture surfaces.
