Objectives: The aim of the study is to compare the effect of different natural sources on teeth whitening.

Materials and Methods: Sound (48) extracted human teeth distributed into four experimental and two control groups. Each group of 8 teeth placed in a plastic tube containing 15 ml of phosphate-buffered saline and 15 ml of tested material. Group 1 contained (15g) of turmeric. Groups 2,3 and 4 contained 15 ml of commercially available sunflower, coconut, and sesame oils respectively. For positive control group 30 ml of 9% (H2O2) was used, while 30 ml of saline used as a negative control group. Tubes placed on a rotating platform shaker for 20 minutes. Teeth are washed with saline and stored at room temperature overnight. The procedure was repeated two times a day for 7 days. Shade was determined for one crown surface using Vita Classical and Vitapan 3D- Master before and after using the rinses.

Results: Difference in means was tested using analysis of variance (ANOVA) followed by Tukey’s post hoc and independent sample t- test as necessary. Analysis was performed using the Statistical Package for Social Science version 17 (SPSS INC Chicago link). All statistical tests were two-sided, and the significance level was set at p < 0.05.

Conclusion: Regardless of the oral beneficial of coconut, sesame oils and turmeric the study shows no evidence suggest these products has role in teeth whitening. Sunflower oil shows significant improvement when compared to other oils. Further studies recommended to assess non-evidence-based teeth whitening methods.
