The effect of herbal mouthwash on oral malodor, plaque and papillary bleeding index
Abstract:
The objectives of this randomized, double-blind clinical study were to determine
the effects of herbal mouthwash on volatile sulphur compounds (VSCs) level, plaque
index (PI) and papillary bleeding index (PBI) in gingivitis subjects and the recurrence
of all parameters after scaling and root planing. Sixty gingivitis subjects who had over
80 parts per billion (ppb) of VSCs were included in the study. Subjects were
distributed into herbal and placebo group. At baseline, VSCs level, PI and PBI were
recorded. Then, they were asked to rinse with the assigned mouthwash. VSCs level
was measured at 30 minutes and 3 hours post-rinsing. For the following 2 weeks,
subjects were rinsed with the assigned mouthwash twice daily after toothbrushing. All
parameters were recorded again at Day 15. In the wash out period, subjects stopped
rinsing with any mouthwash and received scaling and root planing. Then, all baseline
parameters were determined again (Day 0). Following randomized redistribution,
subjects were rinsed with the new assigned mouthwash in the same manner as before
scaling and root planing. All parameters were recorded again at next Day 15.
The results showed that, at 30 minutes and 3 hours post-rinsing, VSCs levels
were significantly different when compared to baseline in both groups. However, no
significant differences were found between groups. At Day 15, significant differences
of VSCs level, PI and PBI were found in both groups when compared to baseline.
VSCs level in herbal group was significantly different from placebo group (p<0.05).
VSCs level at Day 15 after scaling and root planing was not significantly different
when compared to baseline in both groups. However, there was a significant
difference between groups (p<0.05). PI of the placebo group and PBI of herbal group
were significantly different when compared to baseline. No significant differences in
clinical parameters were found between groups.
Conclusion: Herbal mouthwash can significantly reduce oral malodor after
one rinse up to 3 hours in gingivitis subject (p<0.05). Additionally, the herbal
mouthwash can significantly reduce malodor in gingivitis subjects and prevent the
recurrence of VSCs in subjects after scaling and root planing when compared to the
placebo mouthwash after 2 weeks-rinsing (p<0.05).
