Microbial Colonization on Elastomeric Ligatures during Orthodontic Therapeutics: An Overview

Area of Science:

• Dental materials science
• Microbiology
• Orthodontics

Background:

• Fixed orthodontic appliances are linked to increased plaque accumulation, bacterial colonization, and enamel decalcification.
• Studies show varied microbial counts on newer orthodontic materials like elastomeric ligatures during treatment.

Purpose of the Study:

• To review existing research on microbial colonization of orthodontic ligatures.
• To identify the need for further studies on material-based data for elastomeric ligatures.
• To guide the development of oral health-friendly orthodontic ligatures.

Main Methods:

• Literature review of studies on microbial colonization of orthodontic ligatures.
• Analysis of research on elastomeric ligatures and their associated microbial counts.
• Identification of research gaps regarding material properties and microbial biofilm formation.

Main Results:

• Orthodontic treatment with fixed appliances increases microbial colonization on ligatures.
• Elastomeric ligatures show evidence of increased microbial counts, but conclusive material-based data is lacking.
• Current data is insufficient to establish acceptance criteria for elastomeric ligatures based on microbial colonization.

Conclusions:

• There is a need for more research into the microbial colonization of orthodontic ligatures, particularly elastomeric types.
• Future studies should focus on surface chemistries of elastomers and modifications to inhibit microbial biofilms.
• Developing oral health-friendly orthodontic ligatures requires a deeper understanding of material-microbe interactions.
