Abstract
The effects of electrosurgery, retraction cord, and the rotary gingival curettage technique were tested clinically and histologically in dogs. Postoperative periods analyzed ranged from 6 hours to 14 days. All methods induced some kind of minor damage. Recession of clinical magnitude was induced only by rotary gingival curettage. Apical migration of the junctional epithelium was not seen.
摘要
在犬类动物身上对电外科手术、排龈线和旋转式牙龈刮治术的效果进行了临床和组织学测试。分析的术后时间段为6小时至14天。所有方法均引起了某种程度的轻微损伤。只有旋转式牙龈刮治术导致了临床上明显的牙龈退缩。未观察到结合上皮的根尖迁移。
