Summary

This study tested whether an eco-friendly toothbrush works as well as a regular nylon one for controlling cavity risk. About 44 children and adults used either brush type daily and had their cavity risk checked. The goal was to see if the brush material makes a difference in oral health.

(Tavargeri \& Banerjee, 2021)(Lodha, Saraf, \& Jawdekar, 2023) Adults' age Group: Participants must be within the age range of 18 to 35 years consider as being a high caries risk profile according to the cariogram parameters.

(Fouad et al., 2022)
