Purpose: To investigate the impact of interdental toothbrush size on subjective satisfaction among users.
Materials and Methods: A survey was conducted among interdental toothbrush users visiting a dental clinic in Busan, South Korea. Participants were asked about their interdental toothbrush usage and satisfaction levels. The interdental spaces were measured, and appropriate toothbrush sizes were provided accordingly.
Results: A notable increase in subjective satisfaction was found when participants used interdental toothbrushes tailored to their interdental space. Statistical analysis revealed a statistically significant correlation between toothbrush size and satisfaction levels.
Conclusions: Interdental toothbrush size statistically significantly influences subjective satisfaction. To promote oral health, it is imperative to educate individuals about selecting the appropriate toothbrush size. Furthermore, standardisation of interdental toothbrush sizes is recommended to streamline educational efforts and improve user experience across populations.
