[์˜๋ฌธ] This study was undertaken to observe histopathologic changes of periodontal tissues in dogs after ligation of silk and wire on the cervical area of front teeth, and to evaluate the effect of mechanical plaque control. In this experimental study,5 dogs were used and, in each dog, wire ligatures were placed on the cervical area of upper 1, 2 front teeth while silk ligatures were placed on the cervical area of lower 2, 3 front teeth. Then upper right 1, 2 front teeth(Gโ… B) and lower right 2, 3 front teeth (Gโ…กB) were undertaken tooth brushing, while upper left 1, 2 front teeth (Gโ… A) and lower left 2, 3 front teetn (Gโ…กA) were remained to accumulate deposits on the teeth. Thereafter, dogs were serially sacrificed on 0, 1, 2, 4, 5 weeks after ligation of wire and silk. The specimens were obtained in block and made the original slides cut with a thickness of 8ฮผ and stained with hematoxylin and eosin, Gomori's method. The result of this study were as follows: 1. The inflammatory cell infiltrate beneath the crevicular and junctional epithelium was shown in the decreasing order of Gโ…กA, Gโ… A, Gโ…กB, Gโ… B at 5th week. 2. The loss of collagen beneath the crevicular and junctional epithelium was begun at 2nd week in Gโ…กA, 4th week in Gโ… A, and this feature was remarkable at 5th week in Gโ…กA. 3. The proliferation and thickening of crevicular epithelium was begun at 1st week in Gโ…กA, 2nd week in Gโ… A, and it was shown at 5th week in all groups. 4. The breakdown of transseptal fiber was shown at 5th week in Gโ…กA only. 5. The apical shift of junctional epithelium was not induced in an experimental periods, but the thickening of junctional epithelium was resulted at 5th week in Gโ…กA.prohibitio
