The College of Dentistry at the University of Mosul discussed the doctoral thesis titled “The Effect of Different Patterns of Microscopic Bone Perforations on the Rate of Tooth Movement and Associated Tooth Root Resorption in Rabbits” on Thursday, December 19, 2024. Professor Dr. Munir Salem Taha, Vice President of the University for Scientific Affairs, attended part of the discussion.

The thesis presented by researcher Banan Khazaal Yasin Mahmoud in the Pediatric and Orthodontics and Preventive Dentistry branch included a practical component that tested and compared the effect of a new pattern of microscopic bone perforations with two other previously studied patterns on accelerating tooth movement and the associated root resorption during orthodontic treatment in rabbits.

The study indicated that all groups of microscopic bone perforations could effectively accelerate the rate of tooth movement, increase the effectiveness of the periodontal area around the tooth under orthodontic pressure, and stimulate root resorption during orthodontic treatment, although to varying degrees. The group with the new pattern (two superficial horizontal microscopic bone perforations and one additional superficial vertical perforation, along with orthodontic treatment) is likely to be practically desirable for accelerating orthodontic tooth movement, as it showed intermediate rates of acceleration and was capable of stimulating root resorption, which fell between the high group (one deep vertical microscopic bone perforation and orthodontic treatment) and the low group (three superficial horizontal microscopic bone perforations and orthodontic treatment) when tested in rabbits.

The discussion committee was chaired by Professor Dr. Ali Rajeh Mahmoud, with the participation of Professor Dr. Wahda Muhammad Tayeb, Assistant Professor Dr. Mahdi Abdul Hadi Mahdi, Assistant Professor Dr. Mustafa Muadh Hamid, and Assistant Professor Dr. Raghad
