College of Dentistry discussed M.Sc. Thesis entitled “Effects of Incorporating
Sesamum indicum and Vitis vinifera Essential Oils in Preventive Paste after
Bracket Debonding: An In Vitro Study”, on Monday, 5 May 2025 forwarded by
Noor Natheer Abdulqader. The study aimed to evaluate the remineralization
potential of Sesamum indicum and Vitis vinifera seed oils incorporated in a
prepared paste with different concentrations and to compare it with casein
phosphopeptide-amorphous calcium phosphate fluoride paste on enamel caries
induced in bracket deboned tooth surface. The study concluded that Sesamum
indicum and Vitis vinifera seed oils incorporated into the paste with 5 %
concentration has increased the surface microhardness of white spot lesions in the
debonded enamel surface. Also, these oils exhibited some enhancement on surface
roughness of white spot lesions. While, there has been no difference in weight
percentages of calcium, phosphorus and fluoride elements in addition to calcium/
phosphate ratio among all groups, remarkable variations have been observed in
the enamel surface morphology after treatment.
