Introduction: Bay (Syzygium polyanthum) leaf may be used as an extrinsic stain-removing
agent in toothpaste. This study assesses the formula of bay leaf essential oil toothpaste in
terms of physicochemical and extrinsic stain removal properties.
Methods: Using a gel composition with varying quantities of bay leaf essential oil (0%,
0.125%, 0.25%, and 0.5% v/v), tubes of toothpaste were formulated. Commercial stain-removal
toothpaste was used as a positive control. Five toothpastes were evaluated based on their
organoleptic properties, pH, moisture content, foaming ability, abrasiveness, spreadability,
gritty matter, and homogeneity. Extrinsic stain removal evaluation was carried out using 20
bovine teeth that were split into five groups of toothpaste (n=4). The specimens were teastained and submitted to simulated brushing. The colour difference (ΔE) was analysed to
evaluate extrinsic stain removal using the parameter of CIE-Lab (Commision Internacional
de l’Eclairage L*a*b). Using a chromameter, the L*a*b value of the teeth before and after
brushing was used to measure the ΔE value. Data were analysed through one-way ANOVA
with a confidence level of 95%.
Results: All tubes of toothpaste tested met acceptable physicochemical parameter standards.
The bay leaf essential oil toothpaste with 0.25% and 0.5% v/v concentrations, as well as
commercial toothpaste, produced better ΔE values than the 0% v/v group. There were no
statistically significant differences between bay leaf essential oil at 0.5% v/v and commercial
toothpaste (P>0.05).
Conclusion: Results demonstrated that bay leaf essential oil toothpaste had an extrinsic
stain removal effect equivalent to positive control and promoted good physicochemical
characteristics. |
