Abstract |
This study three-dimensionally and histologically assessed the effect of Emdogain® on periodontal healing in replanted teeth in three beagle dogs which were 1 to 2 years old, weighing from 10 to 13 ㎏. Twelve maxillary and mandibular incisors were intentionally extracted and replanted after 15(Group I), 30(Group II) and 60(Group III) minutes of air dry storage with and without the application of Emdogain®. The following conclusions could be drawn from the present investigation. 1. Increased incidence of inflammatory healing response in periodontal tissue was proportional to air dry time in Both control and experimental group(P<0.001). 2. Treatment Group showed lower inflammatory root resorption, especially there were statically significant in Group I, III(P<0.001, Group II : P=0.093). 3. Inflammatory root resorption were mainly occurred in apical third(14, 15-16 section)(P<0.05, 0.001), and cervical third(1 section)(P<0.05). 4. In view of horizontal section of long tooth axis, Main root resorption area were 1, 4, 5 line area(bucco-lingual area)(P<0.01). |
