In Vivo Antiplaque Effect of Three Edible Toothpastes

OBJECTIVES: The objective of this study was to analyse the antibacterial and antiplaque activity of three edible toothpastes with the widest worldwide distribution KidScents(TM), which contains essential oils; Browning B&B(TM), with medicinal plants; and Wysong Probiodent(TM), which contains probiotics. Study DESIGN: The study group was formed of twenty healthy volunteers (dental students) with a good oral health status. Using a balanced randomisation system, all volunteers performed toothbrushing with four products (the three edible toothpastes and water) at intervals of one week. Bacterial vitality in the saliva was analysed by epifluorescence microscopy and plaque regrowth was evaluated using the Turesky-Quigley-Hein plaque index.RESULTS: Bacterial vitality in the saliva was significantly higher after toothbrushing with water (positive control) than with the three toothpastes (P=0.002, P=0.003 and P<0.001, respectively). The plaque index was significantly higher after using these three toothpastes than after toothbrushing with water (P=0.047, P=0.032 and P<0.001, respectively).CONCLUSIONS: The three edible toothpastes analysed have some antimicrobial activity but favour plaque regrowth
