ABSTRACT
This Study Was Conducted On Seven Native Dogs, Each Dog Was Injected By Ethanol Extract Of Propolis. Split Mouth Technique Was Used In Each Maxilla Of The Dogs. The Upper Left Canine Was Injected Sub Mucosal By 1 Ml Of Propolis 500 Mg/l Dissolved In Ethanol, The Right Side Was The Control Side. Two Orthodontic Attachments Were Bonded At The Canine & The Third Molar Of The Same Side, And Connected Together By A NiTi Open Coil Spring. The Distance Between Each Two Attachment Of Each Side Was Measured At Days : 0, 7, 14, 21. Propolis Was Injected Three Times At Days: 0, 7, 14. Sacrificing The Animals Was Done At Day 21 Then Histological Sections From The Canines And Surrounding Alveolar Bone Was Prepared. The Results Showed Non Significant Difference In Orthodontic Tooth Movement Between The 2 Groups. We Concluded That Injection Of Propolis (500mg/l) In Dogs Didn?t Affect The Orthodontic Tooth Movement In Dogs.
