effect of Sodium Lauryl Sulfate Non-containing Dentifrice on Salivary Flow and Oral Malodor

다국어 초록 (Multilingual Abstract)

Objectives: The purpose of this study was to evaluate effects of salivary flow and oral malodor between dentifrice with and without sodium lauryl sulfate(SLS).

Methods: Among 98 volunteers, 39 of normal adults who had lower than average 3.7 cc of unstimulated salivary flow were examined. They were offered first experimental dentifrice(Biotenedentifrice, Laclede co., U.S.A) and second experimental dentifrice(TheraBreath dentifrice, California Breath Clinics, U.S.A.) that did not contained SLS, and control dentifrice which contained SLS. After toothbrushing, they were checked oral malodor by B/B checker(mBA-21, Taiyo, Japan) and unstimulated salivary flowtest.

Results: Before the experiment, 98 of voluteer's unstimulated salivary flow was 4.71 cc for 5 minutes of average time. Normal adult 39 volunteers were chosen which they had lower than 3.7 cc of average unstimulated salivary flow for 5 minutes. By the B/B checker measurement, it showed 32.82 B/B value by using control dentifrice was statistically higher than 25.49 B/B value of first experimental dentifrice and 24.51 B/B value of second experimental dentifrice and that of second experimental dentifrice(p>0.05). Unstimulated salivary flow for 5 minutes showed that 2.556 cc before experiment, 2.779 cc when they used first experimental dentifrice, 2.654 cc when they used second experimental dentifrice, and 2.351 cc when they used control dentifrice.

Conclusion: Precautions for oral malodor patient who has low salivary flow, avoiding dentkfrice containing sodium lauryl sulfate, should be taken.
