On Tuesday, June 13, 2023, a Master’s thesis entitled “Effects of Modifying Orthodontic Adhesive by Thymus Vulgaris and Lavandula Angustifolia Essential Oils on Shear Bond Strength of the Brackets” was discussed in the Department of Pedodontics, Orthodontics and Preventive  at the College of Dentistry / University of Mosul.  The thesis was submitted by the student (Reem Thamer Mosleh Muhammad) aimed to study the effects of modifying the orthodontic adhesive by the essential oils of thyme and lavender seeds on the shear bond strength of orthodontic brackets. The study concluded that lavender, especially the concentration of 1%, may not affect the shear bond strength or the compressive strength of the orthodontic adhesive. In return , thyme reduced the shear and compressive strength of the adhesive.  On the other hand, the results of infrared Fourier transform spectroscopy showed no chemical changes in the properties of the adhesive.  The discussion committee consisted of:

Prof. Dr.  Neam   Fakhri Yassin / College of Dentistry / University of Mosul – Chairman
Lect.  Enas Talab Mohsen / College of Dentistry / University of Mosul – Member
Lect.  Maha Essam Abdulaziz / College of Dentistry / Tikrit University – Member
Prof.Dr.  Ali Rajeh Mahmoud / College of Dentistry / University of Mosul – Member and Supervisor. The thesis was accepted after making  amendments to it.
