Objective:

To investigate the levels of bacterial contamination on toothbrushes and assess patient awareness regarding toothbrush hygiene.

Approach:

Key Findings:

• All toothbrushes showed contamination with tested microorganisms.
• Bacterial levels of Staphylococcus aureus and Enterobacteriaceae increased significantly in toothbrushes used for 3 months compared to 1 month.
• 93% of participants had no prior instruction on proper toothbrush care, and 73% were unaware of contamination risks.
• Storage and handling practices influenced bacterial levels, with toothbrushes stored in bathrooms showing higher contamination.
• Use of a protective bristle cover was linked to lower levels of S aureus and Enterobacteriaceae.

Interpretation:

Toothbrush contamination is prevalent and influenced by user behaviors, while patient awareness of hygiene practices is notably low.

Limitations:

• Small sample size.
• Potential variability in individual hygiene practices and environments.
• Observational nature limits causal relationship establishment.

Conclusion:

The study highlights the commonality of toothbrush contamination and the need for improved patient education on proper toothbrush hygiene.
