Biofilms

1.9K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Development of the Oral Microbiota

38
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

The Oral Microbiota01:27

The Oral Microbiota

41
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Area of Science:

  • Biomaterials Science
  • Dental Research
  • Microbiology

Background:

  • Orthodontic treatment can increase dental biofilm development on brackets.
  • Biofilm accumulation poses challenges for oral hygiene during orthodontic care.

Purpose of the Study:

  • To investigate differences in dental biofilm formation on orthodontic brackets based on material composition.
  • To test the hypothesis that bracket material affects biofilm accumulation.

Main Methods:

  • Evaluation of three bracket types: metallic, composite, and ceramic.
  • In situ assessment using custom orthodontic appliances worn for two 3-day cycles.
  • Quantification of biofilm using spectrophotometry after NaOH extraction and scanning electron microscopy.

Main Results:

  • Composite brackets exhibited significantly higher dental biofilm formation compared to metallic and ceramic brackets.
  • Metallic and ceramic brackets showed comparable levels of biofilm accumulation.
  • Statistical analysis (Three-way ANOVA and Tukey's test) confirmed significant differences among materials.

Conclusions:

  • The in situ model effectively evaluated biofilm accumulation on orthodontic brackets.
  • Composite brackets are more prone to biofilm adhesion than metallic or ceramic alternatives.
  • Material selection may influence biofilm management strategies in orthodontics.
