Abstract

In earlier studies, a combination of 0.25mg/ml green tea and 7.82mg/ml Salvadora persica L. aqueous extracts (Co) had been found to exhibit anti-bacterial and anti-adherence effects against primary plaque colonizers biofilm in vitro and antiplaque effect as a mouthwash for a period of 24h in vivo. The aim of current study was to evaluate anti-plaque efficacy of Co mouthwash for a longer period of 4 days in vivo.

A 4-day plaque re-growth double-blinded randomized crossover trial was carried out. A week after receiving polishing and scaling, all participants (n=14) received polishing at base line and rinsed with 15ml of randomly allocated mouthwashes (either Co, 0.12% chlorhexidine or placebo) twice daily without oral hygiene measures for 4 days. After 24h and 4 days’ time points, plaque index was recorded, and then the participants entered a 6-day washout period with regular oral hygiene measures. The same protocol was repeated for the next 2 mouthwashes.

The Co mouthwash significantly reduced plaque accumulation as compared to Placebo and chlorhexidine).

The Co mouthwash has antiplaque activity for a 4-day period and might be a potential alternative to synthetic mouthwashes.
