【 摘 要 】

Introduction

It was aimed to assess the retention of caries-associated microorganisms on two different manual toothbrushes (conventional and tapered) and to evaluate the influence of multibracket appliances (MB) on the microbial contamination of the brush head.

Methods

50 MB-patients and 50 subjects without MB received a toothbrush (elmex® interX medium short head or meridol®) plus toothpaste (elmex®) for exclusive use and an information sheet with standardised brushing instructions. After 14 days of regular tooth brushing, the brushes were collected and sluiced in Sputasol solution. The suspension was incubated on selective agar plates and the amount of Streptococcus mutans, lactobacilli and Candida albicans for each brush head was assessed.

Results

Regarding the retention of microorganisms, no differences could be detected between the two bristle designs. However, the amount of S. mutans was significantly higher on brushes used by MB-patients (p < 0.005) than on the brushes of subjects without MB. The number of Lactobacilli and C. albicans was minimal in all cases and below statistical evaluation.

Conclusions

During treatment with MB appliances, toothbrushes were contaminated more intensely with S. mutans independent of bristle design. A more frequent replacement of toothbrushes may thus be recommended for patients undergoing MB-treatment.
