摘要

Purpose: To evaluate the extrinsic stain removal efficacy of a new Pro-Argin? formula whitenii dentifrice containing 8.0% arginine, a high cleaning calcium carbonate and 1450 ppm fluoride, as monofluor phosphate, after brushing twice daily for 4 and 8 weeks. Methods: At the baseline visit, 92 adult subjects were stratifi< based on their Lobene Stain Index scores and randomized into two treatment groups; one using the new Pro-Arg formula whitening dentifrice (test group) and the other using the original Pro-Argin formula dentifrice (control group Subjects were instructed to brush twice daily for the duration of the study. Tooth stain evaluations were conducted ; stain area and stain intensity according to the Lobene Stain Index. Results: All 92 enrolled subjects complied with tl protocol and completed the 8-week study. Baseline scores demonstrated no significant differences between the tv treatment groups for the evaluated area and intensity parameters of stain (P> 0.05). At both the 4- and 8-week post-u evaluations, subjects brushing with the test dentifrice demonstrated significant reductions for all stain parameters vers the control (P< 0.05). Relative to the control group, the test group demonstrated reductions in mean stain intensi scores of 9.7% and 17.9% at the 4- and 8-week evaluations, respectively. Corresponding reductions in mean stain an scores for the test group relative to the control were 11.7% and 20.8% at the 4- and 8-week evaluations, respectivel.
