of effectiveness of abrasive and enzymatic action of whitening
toothpastes in removal of extrinsic stains – a clinical trial.
Abstract
Objective
To
compare the effectiveness of abrasive component (perlite/calcium
carbonate) and enzymatic component (papain and bromelain) of whitening
toothpaste in removal of extrinsic stains.
Methods
This
study is a randomized, triple blind and parallel group study in which
90 subjects aged 18–40 years were included. At baseline, stains scores
were assessed by Macpherson's modification of Lobene Stain Index and
subjects were randomly assigned to two groups with 45 subjects in each.
Group 1 used whitening toothpaste with enzymatic action and group 2 with
abrasive action. After 1 month, stain scores were assessed for the
effectiveness of the two toothpastes and 2 months later to check the
stain prevention efficacy. Wilcoxson's test was used to compare between
baseline 1 and 2 months stain scores, and Mann–Witney U-test was applied for intragroup comparison.
Results
The
mean baseline total stain score for the subjects allocated to the
enzymatic toothpaste was 37.24 ± 2.11 which reduced to 30.77 ± 2.48 in
1 month, and for the abrasive paste, total stain reduced from
35.08 ± 2.96 to 32.89 ± 1.95. The reductions in total stain scores with
both the pastes were significant compared with baseline stain scores (at
1 month Group 1, P = 0.0233 and Group 2, P = 0.0324; at 2 months, Group 1 P = 0.0356).
Both the toothpastes proved to be equally good in removal of extrinsic
stains; however, the enzymatic paste showed better results as compared
to abrasive toothpaste.
Conclusion
Whitening
toothpaste with abrasive action and enzymatic action are equally
effective in removal of extrinsic stains; however, whitening toothpaste
with abrasive action needs to be used with caution.
