Stannous-containing positive control, palm oil and oily Vitamin E were able to protect enamel against the erosive challenge performed in an in vitro study recently conducted at the Department of Pediatric Dentistry, Orthodontics and Public Health, Bauru School of Dentistry, University of São Paulo, Bauru, São Paulo, Brazil
The study is published in the Journal of Dentistry.
DanielaRios and colleagues evaluated the in vitro effect of different components of palm oil on enamel in a short-term erosive challenge.
The acquired enamel pellicle (AEP) was previously formed in situ for 2 h. Subsequently, the bovine enamel blocks were treated in vitro according to following solutions: G1–palm oil; G2–85% tocotrienol solution; G3–oily vitamin E; G4–oily vitamin A; G5–deionized water (negative control); G6-stannous-containing solution (Elmex® Erosion Protection Dental Rinse) (positive control).
After application of the treatment solutions (500 µl, 30 s), the blocks were immersed in 0.5% citric acid (pH 2.4) during 30 s (initial erosion). The response variable was the percentage of surface hardness loss. Data were analyzed by one-way ANOVA and Fisher's Test (p < 0.05)
The following findings were analyzed and noted-
- The positive control (G6), palm oil (G1) and oily vitamin E (G3) groups presented the lowest percentage of surface hardness loss, and were statistically different from the negative group (G5) (p < 0.05), and no differences were found between these three groups.
- The 85% tocotrienol solution (G2) and oily vitamin A groups (G4) were not different to the negative control group.
Hence, the authors concluded that "Vitamin E presented similar preventive effect to a commercial mouthwash stannous-containing solution (Elmex® Erosion Protection) against initial erosion and, it can be considered as a promising natural alternative for the formulations of solutions aiming to prevent erosive tooth wear."
The authors further inferred the following-
- Palm oil showed protective effect against enamel erosion as previously published.
- Vitamin E presented similar anti-erosive effect to palm oil and stannous solution.
- Vitamin E is probably the main component of palm oil in preventing enamel erosion.
- Vitamin E can be a natural option for the development of anti-erosive products.
