The effect of 2-O-stearoyl-glycerol 1,3-bisphosphate on the demineralization of dental enamel in vitro.
Parts of the buccal and lingual enamel surfaces of sound human third molars were treated with a test compound, and the non-treated parts served as control. After the treatment both parts were demineralized, and the artificial caries lesions were analyzed by means of quantitative microradiography. Treatment during only 1 minute with an aqueous solution of 1.5 mmol/l of the surface active compound 2-O-stearoyl-glycerol 1,3-bisphosphate (Glydip) resulted in a decrease in the rate of enamel demineralization by about 60%. When Glydip was dissolved in a toothpaste/water slurry it inhibited the demineralization by about 30%. When the enamel was covered by a salivary pellicle prior to the application of the slurry, the inhibition of the demineralization disappeared. However, when Glydip was applied in an aqueous solution, the presence of a salivary pellicle did not interfere with the decreasing effect of Glydip on the demineralization. It is concluded that Glydip has promising properties for its use as an anti-caries agent, in combination with fluoride.
