History of Interdental Brushes: Origins, Developments, Perspectives

Area of Science:

• Oral hygiene practices
• Dental device development
• Periodontal health research

Background:

• Interdental brushes (IDBs) have a documented history from the early 20th century.
• Early evaluations of IDBs were mixed, with evolving perceptions of their efficacy and safety.
• Despite advancements in design and standardization (ISO 16409), proper selection and use remain challenges.

Observation:

• A comprehensive historical review of IDBs reveals a lack of extensive literature compared to other oral hygiene tools.
• Twisted oral hygiene brushes were noted in the late 19th century, with interdental use emerging in the early 20th century.
• IDBs have been in documented use since at least 1960, with research publications increasing from the 1970s.

Findings:

• By the early 21st century, IDBs were often regarded as superior for interdental cleaning.
• Recent literature indicates limited evidence-based data on IDB efficacy, with some studies questioning their superiority over alternatives like dental floss.
• Consumer alternatives like rubber picks are sometimes rated higher, though conclusive assessments are pending.

Implications:

• Further research is needed to provide precise indications and scientifically supported recommendations for various IDB sizes and designs.
• IDBs must demonstrate improved oral health outcomes, widespread demand, and cost-effectiveness to align with Frugal Dentistry principles.
• Future studies should focus on ensuring IDBs are user-friendly and effective across diverse interdental spaces.
